1,668,033 | 1 | null | null | 10 | 3,598 | I have a scenario where I need to localized values of objects in my database.
Let's say you have an application that can create animals, if the user is english the value of the "Name" property of an animal would be entered as "Cat" in the UI whereas it would be entered as "Chat" in french.
The animal culture table would contain 2 records pointing to the same animal in the parent table.
When reading values back, if the value of "Name" does not exist in the user culture the default value (value the object was originally created with) would be used.
The following diagrams demonstrate how the data is stored in SQL:
I'm trying to map this schema to an object model using the Entity Framework, I'm a bit confused as to what the best way to approach the problem.
Is EF appropriate for this? Should I used EF4?
This EF model will be used by .NET RIA Services.
Thanks,
Pierre-Yves Troel

1,670,970 | 1 | 3,933,416 | null | 1,391 | 894,445 | I have two branches. Commit `a` is the head of one, while the other has `b`, `c`, `d`, `e` and `f` on top of `a`. I want to move `c`, `d`, `e` and `f` to first branch without commit `b`. Using cherry pick it is easy: checkout first branch cherry-pick one by one `c` to `f` and rebase second branch onto first.

1,671,210 | 1 | 1,703,359 | null | 1 | 10,178 | I am working on an ongoing project where I want to align the links of a chain so that it follows the contours of a Bezier curve. I am currently following the steps below.
1. Drawing the curve.
2. Use a display list to create one link of the chain.
3. Use a FOR loop to repeatedly call a function that calculates the angle between two points on the curve, returns the angle and the axis around which the link should be rotated.
4. Rotate by the angle "a" and translate to new position, place the link at the new position.
Edit: I should also say that the centres of the two half torus must lie on the Bezier curve.
Also I am aware that the method I use to draw the torus I tedious, I will use TRIANGLE_FAN or QUAD_STRIP later on to draw the torus in a more efficient way.
While at first glance this logic looks like it would render the chain properly, the end result is not what I had imagined it to be. Here is a picture of what the chain looks like.
I read that you have to translate the object to the origin before rotation? Would I just call glTranslate(0,0,0) and then follow step 4 from above?
I have included the relevant code from what I have done so far, I would appreciate any suggestions to get me code work properly.
```
/* this function calculates the angle between two vectors oldPoint and new point contain the x,y,z coordinates of the two points,axisOfRot is used to return the x,y,z coordinates of the rotation axis*/
double getAxisAngle(pointType oldPoint[],

axisOfRot->x= oldPoint->y * newPoint->z - oldPoint->z * newPoint->y;
axisOfRot->y= oldPoint->z * newPoint->x - oldPoint->x * newPoint->z;

normA=sqrt(oldPoint->x * oldPoint->x + oldPoint->y * oldPoint->y + oldPoint->z *

tmpPoint[1] = oldPoint->y * newPoint->y;
tmpPoint[2] = oldPoint->z * newPoint->z;
for(i=0;i<=2;i++)
AB+=tmpPoint[i];
AB /= (normA * normB);
return angle = (180/PI)*acos(AB);
}
/* this function calculates and returns the next point on the curve give the 4 initial points for the curve, t is the tension of the curve */
void bezierInterpolation(float t,pointType cPoints[],

}
/* the two lists below are used to create a single link in a chain, I realize that creating a half torus using cylinders is a bad idea, I will use GL_STRIP or TRIANGLE_FAN once I get the alignment right
*/
torusList=glGenLists(1);
glNewList(torusList,GL_COMPILE);
for (i=0; i<=180; i++)
{
degInRad = i*DEG2RAD;
glPushMatrix();
glTranslatef(cos(degInRad)*radius,sin(degInRad)*radius,0);
glRotated(90,1,0,0);
gluCylinder(quadric,Diameter/2,Diameter/2,Height/5,10,10);
glPopMatrix();
}
glEndList();
/*! create a list for the link , 2 half torus and 2 columns */
linkList = glGenLists(1);
glNewList(linkList, GL_COMPILE);

The problem is, that I want to fill my hint list (see picture below) with data, which I will receive via a HTTP/JSON query. So I'm not sure if using a [ContentProvider](http://developer.android.com/guide/topics/providers/content-providers.html) as used in the above example is the right thing to do. Can I access the hint list of the SearchBox in some way more direct?

1,676,882 | 1 | 1,752,092 | null | 2 | 1,426 | I'm making a sample GUI for a new application we are developing at work. The language has already been decided for me, but I am allowed to use any 3rd party DLLs or add-ins or whatever I need in order to make the GUI work as seamlessly as possible.
They want it very mac/ubuntu/vista/Windows 7-like, so I've come up with some very interesting controls and pretty GUI features. One of which are some growing/shrinking buttons near the top of the screen that increase in size when you mouse over them (it uses the distance formula to calculate the size it needs to increase by). When you take your mouse off of the controls, they shrink back down. The effect looks very professional and flashy, except that there is a ghosting effect as the button shrinks back down (and the buttons to the right of it since they are fixed-at-the-hip).
Here is what the buttons look like in the designer:
Here are some code snippets that I am using to do this:
pops child buttons underneath when parent is hovered
```

control.Visible = True
End If
Next
End Sub

What I know:
1. If the form didn't have a background image, I wouldn't have the ghosting problem.
2. If this were just a normal button I am drawing, I probably wouldn't have the ghosting problem.
What I've done, and how I've tried to fix it:
1. Ensuring the form's doublebuffering is turned on (it was)
2. Manually doublebuffering using the bufferedGraphics class (did not help or made it worse)
3. Convince the designers that it doesn't need background images or the pretty glass buttons (no go)
4. Run Invalidate() on the rectangle containing the form (did not help)
5. Run Refresh() on the form (fixed the ghosting, but now the entire screen flashes as it reloads image)
6. Sit in the corner of my cubicle and cry softly to myself (helped the stress, but also did not fix issue)
What I am looking for are the answers to these questions:
1. Does anyone have any idea how to get rid of the ghosting I'm describing? Should I focus on changing the size less often? should I be focusing on buffering the background image?
2. Are there other technologies I should be using here? Are there ActiveX controls that would be better at this than .NET user inherited ones? Is it possible to make a DirectX user-control to use the graphics card to draw itself?
3. Is there something else I'm not thinking of here?
~~~~~~~~~~~~~~~~~~~~~~~~~ Update 1: 11/17/2009 9:21 AM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I've improved the efficiency of the draw methods by first checking to see if they need to be redrawn by checking what the new values will be vs what they already are(code changed above). This fixes some of the ghosting, however the core problem still remains to be solved.

1,678,068 | 1 | 1,678,189 | null | 6 | 1,496 | I would like to understand why on .NET there are nine integer types: `Char`, `Byte`, `SByte`, `Int16`, `UInt16`, `Int32`, `UInt32`, `Int64`, and `UInt64`; plus other numeric types: `Single`, `Double`, `Decimal`; and all these types have no relation at all.
When I first started coding in C# I thought "cool, there's a `uint` type, I'm going to use that when negative values are not allowed". Then I realized no API used `uint` but `int` instead, and that `uint` is not derived from `int`, so a conversion was needed.
What are the real world application of these types? Why not have, instead, `integer` and `positiveInteger` ? These are types I can understand. A person's age in years is a `positiveInteger`, and since `positiveInteger` is a subset of `integer` there's so need for conversion whenever `integer` is expected.
The following is a diagram of the type hierarchy in XPath 2.0 and XQuery 1.0. If you look under `xs:anyAtomicType` you can see the numeric hierarchy `decimal` > `integer` > `long` > `int` > `short` > `byte`. Why wasn't .NET designed like this? Will the new framework "Oslo" be any different?

```

+(id) newData {
DataPoint *myNewData;
myNewData = [[DataPoint alloc] init];
return myNewData;

```

DataPoint *myData;
myData = [DataPoint newData];

Also should
```
myNewData = [[DataPoint alloc] init];

be (or does it not matter)
```
myNewData = [[self alloc] init];

# EDIT_002:
Strange, when I add the autorelease I get ...
# EDIT_003:
@Dave DeLong, one final question, what your saying is its perferable to:
```
+(id) dataPoint {
return [[[self alloc] init] autorelease];
}
```
rather than (where you would release in main)
```
+(id) new {

1,684,004 | 1 | 1,684,521 | null | 8 | 6,800 | I'm having trouble with memory fragmentation in my program and not being able to allocate very large memory blocks after a while. I've read the related posts on this forum - mainly [this](https://stackoverflow.com/questions/60871/how-to-solve-memory-fragmentation) one. And I still have some questions.
I've been using a memory space [profiler](http://hashpling.org/asm/) to get a picture of the memory. I wrote a 1 line program that contains cin >> var; and took a picture of the memory:
Where on the top arc - green indicates empty space, yellow allocated, red commited. My question is what is that allocated memory on the right? Is it the stack for the main thread? This memory isn't going to be freed and it splits the continuous memory that I need. In this simple 1 line program the split isn't as bad. My actual program has more stuff allocated right in the middle of the address space, and I don't know where it's comming from. I'm not allocating that memory yet.
1. How can I try solve this? I was thinking of switching to something like nedmalloc or dlmalloc. However that would only apply to the objects I allocate explicitly myself, whereas the split shown in the picture wouldn't go away? Or is there a way to replace the CRT allocation with another memory manager?
2. Speaking of objects, are there any wrappers for nedmalloc for c++ so I can use new and delete to allocate objects?

As you can see, "Blambo" is a JLabel with an opaque, red background. The label sits on top of a little grey bar that has a single pixel blackish border all the way around it. I'd like my red warning to match the bar it's sitting on more nicely, i.e. I either need to make it two pixels shorter and move it down a pixel or I need to apply the same single pixel border to the top and bottom only. Of those two, the first is probably preferable as this piece of code is shared with other labels.
The code in question:
```
bgColor = Color.red;
textColor = Color.white;
setBackground(bgColor);
setOpaque(true);
// This line merely adds some padding on the left
setBorder(Global.border_left_margin);
setForeground(textColor);
setFont(font);

```

There will be an image taken of the ceiling. The ceiling will have markers placed on it so the orientation of the camera can be determined. The pictures will always be taken facing straight up. My goal is to detect one of these markers in the image and determine its rotation. So rotation and scaling(to a lesser extent) will be the two primary factors used in the image detection. I will be writing the software in either C# or matlab(not quite sure yet).
For example, the marker might be an arrow like this:
An image taken of the ceiling would contain markers. The software needs to detect a single marker and determine that it has been rotated by 170 degrees.
I have no prior experience with image analysis. I know image processing is a fairly broad topic and was hoping to get some advice on which direction I should take and which techniques would be best for my application. Thanks!

The file I'm having problems with is named:

When I pass it to `WebView`, and it shows the error page, it shows it as:
```
"file:///android_asset/ContentRoot/Photos/XXX%20Software%20Logo%20-%20jpg%20-%2075%.JPG"

I then tried running `URLEncoder.encode()` on it and got the error page with the URL presented as:
```
"file:///android_asset/ContentRoot/Photos/XXX+Software+Logo+-+jpg+-+75%.JPG"

Neither of these URLs were able to open the file (and they both look okay to me). Anyone have any ideas?
If I encode the `%` by hand (using `%25`, as commonsware.com suggested) then it loads the image, but it tries to parse it as text, not as an image, so I just get a lot of (basically) garbage.
Also, referring to the image in an HTML document with a relative URL isn't working (probably because it's not being parsed as an image?):

But I can't debug any dynamic loading JavaScript. Because all of the loaded JavaScript will be evaluated by the "eval" function.
I found one way to create new JavaScript by using the following script to dynamically create the script into the header of current document. All loaded scripts will be displayed in the HTML DOM (and you can use any debugger to find it).
```
var script = document.createElement('script')
script.setAttribute("type","text/javascript")
script.text = "alert('Test!');";
document.getElementsByTagName('head')[0].appendChild(script);
```
By the way, most debuggers (IE8 Developer Toolbar, Firebug and Google Chrome) can’t set breakpoints in any dynamic script. Because debuggable scripts must be loaded the first time after the page is loaded.
Do you have an idea for debugging when using dynamic script content or a dynamic file?
You can use the following xhtml file for trying to debug someVariable value.
```
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

script.text = "var someVariable = 0;\n" +
"someVariable = window.outerWidth;\n" +
"alert(someVariable);";
document.getElementsByTagName('head')[0].appendChild(script);
}
</script>
</head>
<body onload="page_load();">
</body>
</html>
```
From answer, I just test it in FireBug. The result should be displayed like below images.
Both of the above images show inserting "debugger;" statement in some line of the script can fire a breakpoint in the dynamic loading script. However, both debuggers do not show any code at breakpoint. Therefore, it is useless to this

1,707,620 | 1 | 1,711,158 | null | 89 | 25,148 | I've been implementing an adaptation of [Viola-Jones' face detection algorithm](http://scholar.google.com/scholar?cluster=6119571473300502765). The technique relies upon placing a subframe of 24x24 pixels within an image, and subsequently placing rectangular features inside it in every position with every size possible.
These features can consist of two, three or four rectangles. The following example is presented.
They claim the exhaustive set is more than 180k (section 2):
> Given that the base resolution of the detector is 24x24, the exhaustive set of rectangle features is quite large, over 180,000 . Note that unlike the Haar basis, the set of rectangle
features is overcomplete.
The following statements are not explicitly stated in the paper, so they are assumptions on my part:
1. There are only 2 two-rectangle features, 2 three-rectangle features and 1 four-rectangle feature. The logic behind this is that we are observing the difference between the highlighted rectangles, not explicitly the color or luminance or anything of that sort.
2. We cannot define feature type A as a 1x1 pixel block; it must at least be at least 1x2 pixels. Also, type D must be at least 2x2 pixels, and this rule holds accordingly to the other features.
3. We cannot define feature type A as a 1x3 pixel block as the middle pixel cannot be partitioned, and subtracting it from itself is identical to a 1x2 pixel block; this feature type is only defined for even widths. Also, the width of feature type C must be divisible by 3, and this rule holds accordingly to the other features.
4. We cannot define a feature with a width and/or height of 0. Therefore, we iterate x and y to 24 minus the size of the feature.
Based upon these assumptions, I've counted the exhaustive set:
```
const int frameSize = 24;
const int features = 5;
// All five feature types:
const int feature[features][2] = {{2,1}, {1,2}, {3,1}, {1,3}, {2,2}};
int count = 0;
// Each feature:
for (int i = 0; i < features; i++) {
int sizeX = feature[i][0];
int sizeY = feature[i][1];
// Each position:
for (int x = 0; x <= frameSize-sizeX; x++) {
for (int y = 0; y <= frameSize-sizeY; y++) {
// Each size fitting within the frameSize:
for (int width = sizeX; width <= frameSize-x; width+=sizeX) {
for (int height = sizeY; height <= frameSize-y; height+=sizeY) {
count++;
}
}
}
}
}
```
The result is .
The only way I found to approximate the "over 180,000" Viola & Jones speak of, is dropping assumption #4 and by introducing bugs in the code. This involves changing four lines respectively to:
```
for (int width = 0; width < frameSize-x; width+=sizeX)
for (int height = 0; height < frameSize-y; height+=sizeY)
```
The result is then . (Note that this will effectively prevent the features from ever touching the right and/or bottom of the subframe.)
Now of course the question: have they made a mistake in their implementation? Does it make any sense to consider features with a surface of zero? Or am I seeing it the wrong way?

1,711,784 | 1 | 1,712,019 | null | 6 | 5,871 | I'm currently working on writing a version of the MATLAB [RegionProps](http://www.mathworks.com/help/images/ref/regionprops.html) function for [GNU Octave](http://www.gnu.org/software/octave/). I have most of it implemented, but I'm still struggling with the implementation of a few parts. I had [previously asked](https://stackoverflow.com/questions/1532168/what-are-the-second-moments-of-a-region) about the of a region.
This was helpful theoretically, but I'm having trouble actually implementing the suggestions. I get results wildly different from MATLAB's (or common sense for that matter) and really don't understand why.
Consider this test image:
We can see it slants at 45 degrees from the X axis, with minor and major axes of 30 and 100 respectively.
Running it through MATLAB's `RegionProps` function confirms this:
```
MajorAxisLength: 101.3362
MinorAxisLength: 32.2961
Eccentricity: 0.9479
Orientation: -44.9480
```
Meanwhile, I don't even get the axes right. I'm trying to use [these formulas](http://en.wikipedia.org/wiki/Image_moments#Central_moments) from Wikipedia.
My code so far is:
### raw_moments.m:
```
function outmom = raw_moments(im,i,j)
total = 0;
total = int32(total);
im = int32(im);
[height,width] = size(im);
for x = 1:width;
for y = 1:height;
amount = (x ** i) * (y ** j) * im(y,x);
total = total + amount;
end;
end;
outmom = total;
```
### central_moments.m:
```
function cmom = central_moments(im,p,q);
total = 0;
total = double(total);
im = int32(im);
rawm00 = raw_moments(im,0,0);
xbar = double(raw_moments(im,1,0)) / double(rawm00);
ybar = double(raw_moments(im,0,1)) / double(rawm00);
[height,width] = size(im);
for x = 1:width;
for y = 1:height;
amount = ((x - xbar) ** p) * ((y - ybar) ** q) * double(im(y,x));
total = total + double(amount);
end;
end;
cmom = double(total);
```
And here's my code attempting to use these. I include comments for the values I get
at each step:
```
inim = logical(imread('135deg100by30ell.png'));
cm00 = central_moments(inim,0,0); % 2567
up20 = central_moments(inim,2,0) / cm00; % 353.94
up02 = central_moments(inim,0,2) / cm00; % 352.89
up11 = central_moments(inim,1,1) / cm00; % 288.31
covmat = [up20, up11; up11, up02];
%[ 353.94 288.31
% 288.31 352.89 ]
eigvals = eig(covmat); % [65.106 641.730]
minoraxislength = eigvals(1); % 65.106
majoraxislength = eigvals(2); % 641.730
```
I'm not sure what I'm doing wrong. I seem to be following those formulas correctly, but my results are nonsense. I haven't found any obvious errors in my moment functions, although honestly my understanding of moments isn't the greatest to begin with.
Can anyone see where I'm going astray? Thank you very much.

binary region of interest (ROI) mask,
BW, from an ROI polygon, represented
by the vectors x and y. The size of BW
is m-by-n. `poly2mask` sets pixels in BW
that are inside the polygon (X,Y) to 1
and sets pixels outside the polygon to
0.
Given such a binary mask `BW` of a convex quadrilateral, what would be the most efficient way to determine the four corners?
E.g.,
Use `edge` to find the bounding lines, the Hough transform to find the 4 lines in the edge image and then find the intersection points of those 4 lines or use a corner detector on the edge image. Seems complicated, and I can't help feeling there's a simpler solution out there.
Btw, `convhull` doesn't always return 4 points (maybe someone can suggest `qhull` options to prevent that) : it returns a few points along the edges as well.
[Amro's answer](https://stackoverflow.com/questions/1711916/find-the-corners-of-a-polygon-represented-by-a-region-mask/1713400#1713400) seems quite elegant and efficient. But there could be multiple "corners" at each real corner since the peaks aren't unique. I could cluster them based on and average the "corners" around a real corner but the main problem is the use of `order(1:10)`.
Is `10` enough to account for all the corners or will this exclude a "corner" at a real corner?

1,713,335 | 1 | 52,612,432 | null | 183 | 216,045 | I can write something myself by finding zero-crossings of the first derivative or something, but it seems like a common-enough function to be included in standard libraries. Anyone know of one?
My particular application is a 2D array, but usually it would be used for finding peaks in FFTs, etc.
Specifically, in these kinds of problems, there are multiple strong peaks, and then lots of smaller "peaks" that are just caused by noise that should be ignored. These are just examples; not my actual data:
1-dimensional peaks:
[](https://i.stack.imgur.com/eJvFQ.jpg)
2-dimensional peaks:
The peak-finding algorithm would find the location of these peaks (not just their values), and ideally would find the true inter-sample peak, not just the index with maximum value, probably using [quadratic interpolation](https://ccrma.stanford.edu/~jos/sasp/Quadratic_Peak_Interpolation.html) or something.
Typically you only care about a few strong peaks, so they'd either be chosen because they're above a certain threshold, or because they're the first peaks of an ordered list, ranked by amplitude.
As I said, I know how to write something like this myself. I'm just asking if there's a pre-existing function or package that's known to work well.
I [translated a MATLAB script](http://gist.github.com/250860) and it works decently for the 1-D case, but could be better.
sixtenbe [created a better version](https://gist.github.com/1178136) for the 1-D case.

1,729,596 | 1 | 6,602,701 | null | 10 | 7,922 | I've been trying to figure out a decent way to smoothly animate a frame size change on a UILabel, without a weird starting jump redraw. What happens by default is that when I do something like this:
```
// Assume myLabel frame starts as (0, 0, 100, 200)
[UIView beginAnimations:@"myAnim" context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:1.0];
myLabel.frame = CGRectMake(0.0, 0.0, 50, 100);
[UIView commitAnimations];
```
I get a smooth animation with the label, the way that it does it is that it takes the redrawn image layer for the destination size of the label and streches the content to fit the current then animates to the destination rect. This ends up with a very bizarre jump in the text display. Here are two images showing the pre-animation look, and then just after the animation starts:
Pre-Animation
Post-Animation
I have tried to use just the layer to animate this, but I still get the same issues.
So the question is, how can I avoid this?
Thanks for any help,
Scott

1,730,824 | 1 | 1,731,170 | null | 1 | 1,806 | I am currently using Q-Learning to try to teach a bot how to move in a room filled with walls/obstacles. It must start in any place in the room and get to the goal state(this might be, to the tile that has a door, for example).
Currently when it wants to move to another tile, it will go to that tile, but I was thinking that in the future I might add a random chance of going to another tile, instead of that. It can only move up, down, left and right. Reaching the goal state yields +100 and the rest of the actions will yield 0.
I am using the algorithm found [here](http://people.revoledu.com/kardi/tutorial/ReinforcementLearning/Q-Learning-Algorithm.htm), which can be seen in the image bellow.
Now, regarding this, I have some questions:
1. When using Q-Learning, a bit like Neural Networks, I must make distinction between a learning phase and a using phase? I mean, it seems that what they shown on the first picture is a learning one and in the second picture a using one.
2. I read somewhere that it'd take an infinite number of steps to reach to the optimum Q values table. Is that true? I'd say that isn't true, but I must be missing something here.
3. I've heard also about TD(Temporal Differences), which seems to be represented by the following expression: Q(a, s) = Q(a, s) * alpha * [R(a, s) + gamma * Max { Q(a', s' } - Q(a, s)]
which for alpha = 1, just seems the one shown first in the picture. What difference does that gamma make, here?
4. I have run in some complications if I try a very big room(300x200 pixels, for example). As it essentially runs randomly, if the room is very big then it will take a lot of time to go randomly from the first state to the goal state. What methods can I use to speed it up? I thought maybe having a table filled with trues and falses, regarding whatever I have in that episode already been in that state or not. If yes, I'd discard it, if no, I'd go there. If I had already been in all those states, then I'd go to a random one. This way, it'd be just like what am I doing now, knowing that I'd repeat states a less often that I currently do.
5. I'd like to try something else than my lookup table for Q-Values, so I was thinking in using Neural Networks with back-propagation for this. I will probably try having a Neural Network for each action (up, down, left, right), as it seems it's what yields best results. Are there any other methods (besides SVM, that seem way too hard to implement myself) that I could use and implement that'd give me good Q-Values function approximation?
6. Do you think Genetic Algorithms would yield good results in this situation, using the Q-Values matrix as the basis for it? How could I test my fitness function? It gives me the impression that GA are generally used for things way more random/complex. If we watch carefully we will notice that the Q-Values follow a clear trend - having the higher Q values near the goal and lower ones the farther away you are from them. Going to try to reach that conclusion by GA probably would take way too long?

1,741,806 | 1 | null | null | 0 | 394 | with my Repository classes, I use `LinqToSql` to retrieve the data from the repository (eg. Sql Server 2008, in my example). I place the result data into a `POCO` object. Works great :)
Now, if my `POCO` object has a child property, (which is another `POCO` object or an IList), i'm trying to figure out a way to populate that data. I'm just not too sure how to do this.
Here's some sample code i have. Please note the last property I'm setting. It compiles, but it's not 'right'. It's not the POCO object instance .. and i'm not sure how to code that last line.
```
public IQueryable<GameFile> GetGameFiles(bool includeUserIdAccess)
{
return (from q in Database.Files
select new Core.GameFile
{
CheckedOn = q.CheckedOn.Value,
FileName = q.FileName,
GameFileId = q.FileId,
GameType = (Core.GameType)q.GameTypeId,
IsActive = q.IsActive,
LastFilePosition = q.LastFilePosition.Value,
UniqueName = q.UniqueName,
UpdatedOn = q.UpdatedOn.Value,
// Now any children....
// NOTE: I wish to create a POCO object
// that has an int UserId _and_ a string Name.
UserAccess = includeUserIdAccess ?
q.FileUserAccesses.Select(x => x.UserId).ToList() : null
});
}
```
Notes:
- -
### Update
I've now got a suggestion to extract the children results into their respective `POCO` classes, but this is what the `Visual Studio Debugger` is saying the class is :-
Why is it a `System.Data.Linq.SqlClient.Implementation.ObjectMaterializer<..>`
`.Convert<Core.GameFile>` and not a `List<Core.GameFile>` containing the `POCO's`?
Any suggestions what that is / what I've done wrong?
### Update 2:
this is what i've done to extract the children data into their respective poco's..
```
// Now any children....
UserIdAccess = includeUserIdAccess ?
(from x in q.FileUserAccesses
select x.UserId).ToList() : null,
LogEntries = includeUserIdAccess ?
(from x in q.LogEntries
select new Core.LogEntry
{
ClientGuid = x.ClientGuid,
ClientIpAndPort = x.ClientIpAndPort,
// ... snip other properties

1,743,331 | 1 | 1,748,752 | null | 1 | 1,162 | I need a functionality to have optional columns in a LINQ to SQL definition. So that LINQ to SQL normally ignores this column within selects and updates etc.
But if a select contains a value for this column it should use this value.
Long version:
## The Scenario
I've the following tables:
If Field.FieldViews.Count() greater than 0 than should this field be visible.
### The Problem
If I check the visibility as mentioned above with:
```
Field.FieldViews.Count()
```
Than it makes a single query to the database for every field.
So in my project sometimes up to 1000x
## My Solution
I wrote a stored procedure:
```
SELECT
f.*,
(SELECT COUNT(*) FROM [fieldViews] v WHERE v.fieldId = f.fieldId) AS Visible
FROM [fields] f
WHERE
f.X BETWEEN @xFrom AND @xTo AND
f.Y BETWEEN @yFrom AND @yTo
```
To use this additional column I added the following code:
```
public partial class Field
{
private bool visible = false;
[Column(Storage = "Visible", DbType = "INT")]
public bool Visible
{
get
{
return visible;
}
set
{
visible = value;
}
}
}
```
But ...
### The Problem
If I fetch entries from Fields table without the stored procedure:
```
from d in DataContext.Fields select d;
```
I got the following error:
> `Bad Storage property: 'Visible' on member 'Models.Field.Visible'.`
So I added the column "Visible" to the database table:
```
ALTER TABLE dbo.Fields ADD
Visible int NOT NULL CONSTRAINT DF_Fields_Visible DEFAULT 0
```
But …
### Next problem
I have fetched some Field objects using the stored procedure.
Now I make some changes to some of these objects.
If I now try to submit these changes it doesn't work. Looking at the generated query unveils the reason:
```
UPDATE [dbo].[Fields]
SET [X] = @p3
WHERE ([FieldId] = @p0) AND ([X] = @p1) AND ([Y] = @p2) AND ([Visible] = 3)
```
The problem here is, that it uses the "Visible" column in the where statement. But the "Visible" column is always 0.
Visible is only greater than 0 if I fetch data using the stored procedure...
## What I need
Something like the ColumnAttribute where the column is not required
or
a way to remove a column from the where statement when updating.

## Happy Tuesday everyone :)
I noticed I was using the same fonts over again in several of my Sub Classes, so I figured I'd just make a to handle all those.
Anyways I'm scratching my head around how to get those TextFormats created in my into my other Classes cleanly. I don't believe I'm doing this the correct way, but currently I'm getting this error msg:
I want to pass the avant97 TextFormat into my Frame Class to style the Footer text
## Below is my Fonts Class.
```
package src.model
{
import flash.text.*;
public class Fonts
{
public static var data:Object = {};
public static var avant97 = new TextFormat(); // Footer copy
public static var avantFF = new TextFormat(); // Navigation Copy
public static var avant0s = new TextFormat(); // Thumbnail Titles
avant97.font = (new AvantGrande() as Font).fontName;
avant97.size = 16;
avant97.color = 0x979797;
avant97.align = TextFormatAlign.CENTER;
avantFF.font = (new AvantGrande() as Font).fontName;
avantFF.size = 16;
avantFF.color = 0xFFFFFF;
avantFF.align = TextFormatAlign.CENTER;
avant00.font = (new AvantGrande() as Font).fontName;
avant00.size = 16;
avant00.bold = true;
avant00.color = 0x000000;
avant00.align = TextFormatAlign.LEFT;
}
}
```

## Here is my Frame class where I'm trying to attach avant97 to a TextField:
```

import flash.events.Event;
// ☼ --- Imported Classes
import src.events.CustomEvent;

}
// ☼ --- Init

footer.graphics.beginFill(0x000);
footer.graphics.drawRect(0,0,800,56);
footer.graphics.endFill();
footer.y = stage.stageHeight - footer.height;
var footText:TextField = new TextField();
footText.defaultTextFormat = footFont; // Fail x 2!
footText.antiAliasType = flash.text.AntiAliasType.NORMAL;
footText.selectable = false;
footText.mouseEnabled = false;
footText.wordWrap = true;
footText.width = 800;
footText.height = 30;
footText.text = footCopy;
// ☼ --- Place Footer & Copy
footer.addChild(footText);
addChild(footer);
trace("Frame added --- √"+"\r");
this.removeEventListener(Event.ADDED_TO_STAGE, init);
}
}
```
}
Basically I got the [idea for the static var data object from here][2]
But maybe his example only works for actual data? Not TextFormats?

Also, how could I reproduce this effect in C#/VB.NET? (preferably WinForms as I don't really know WPF yet.)
I also noticed that the origin of the "fade" is based on the cursor position within the image (go ahead, try it now, you'll see what I mean!)
I suppose I could delve into the source [over at MDC](https://developer.mozilla.org/en/download_mozilla_source_code), but I thought someone here might already be familiar with this technique.

1,755,591 | 1 | 1,756,398 | null | 17 | 8,107 | I'm trying to create a django database that records all my comic purchases, and I've hit a few problems. I'm trying to model the relationship between a comic issue and the artists that work on it.
A comic issue has one or more artists working on the issue, and an artist will work on more than a single issue. In addition, the artist has a role relating to what they did on the comic – creator (all the work on that issue), writer (wrote the script), drawer (drew the complete comic), pencils, inks, colours or text, and there may be several artists in a given role.
This gives me a database model like: 
I then translate this into the following Django model.
As I require additional data on the relationship, I believe I have to use a separate class to handle the relationship, and hold the additional
```
class Artist(models.Model):
name = models.CharField(max_length = 100)
def __unicode__(self):
return self.name
class ComicIssue(models.Model):
issue_number = models.IntegerField()
title = models.TextField()
artists = models.ManyToManyField(Artist, through='IssueArtist')
def __unicode__(self):
return u'issue = %s, %s' % (self.issue_number, self.title)
class IssueArtist(models.Model):
roles = ( (0, "--------"),
(1, "Creator"),
(2, "Writer"),
(3, "Drawer"),
(4, "Pencils"),
(5, "Inks"),
(6, "Colours"),
(7, "Text"),
)
artist = models.ForeignKey(Artist)
issue = models.ForeignKey(ComicIssue)
role = models.IntegerField(choices = roles)
```
My questions are:
1) Does this seem a correct way of modelling this?
2) If I don't use the `through='IssueArtist'` feature, I can add relationships by using the `artists.add()` function. If I do use this, I get an error `'ManyRelatedManager' object has no attribute 'add'`. Do I have to manually manage the relationship by creating `IssueArtist()` instances, and explicitly searching the relationship table?
NB. I am using Django 1.0, at the moment

1,758,484 | 1 | 1,758,551 | null | 11 | 31,389 | I'm creating a website for my schools "Math Relay" competition.
I have a "Container" div (with a white background), then a top-bar, left-bar, and right-bar div inside the container.
left-bar and right-bar are both floated inside "Container".
However, if you look in the image below you can see the right-bar has the grey background showing beneath it. If "Container" is truly containing both top, left and right bar then it should be the containers background which shows through and the bottom should all be at a uniform level with a white color.
Instead, it seems that container isn't fully containing the left & right bar and therefore the actual body background shows through on the bottom of the right bar.
Here is my CSS:
```
#container {
margin: 0 auto;
width: 750px;
background-color: #ffffff; }
#top-panel {
background-color: #000000;
text-align: left;
width: 100%;
height: 88px;
float: left; }
#left-panel {
clear: left;
text-align: center;
background-color: #ffffff;
border-right: 1px dashed #000000;
float: left;
width: 250; }
#right-panel {
background-color: #ffffff;
float: left;
width: 499; }
```
How can I make the "container" truly contain the divs inside it so the grey background will not show up underneath my right-panel and create my uneven level at the bottom?

I want to track groups and group members via SQL.

```
select * from Table where GroupID=1
```

My problem is I have millions of rows added to this table and I would like it to do some sort of presorting about GroupID to make lookups as fast as possible.
I'm thinking of a scenario where it would have nested tables, where each sub table would contain a groupID's members. (Illustrated below)
This way when I wanted to select each GroupMembers, the structure in SQL would already be nested and not as to expensive look up as would trolling through rows.
Does such a structure exist, in essence, a table that would pivot around the groupID ? Is indexing the table about groupID the best/only option?

Hi all !
I want to create a small round static percent indicator in CSS but I can't find the solution.
The squared indicator at left is ok, but so ugly, I want it round !
I have tried with rounded corner (cf indicators at the right of the screenshot), and I wonder if there is possibility to add a rounded mask to hide the corners (cf. css3 mask : [http://webkit.org/blog/181/css-masks/](http://webkit.org/blog/181/css-masks/)), but it seems like it's only for img...
The solution can works only on webkit browsers, because it's for a mobile webapp.
Here is my code to create the (ugly) indicator in the image above :
```
<div class="meter-wrap">
<div class="meter-value" style="background-color: #489d41; width: 70%;">
<div class="meter-text"> 70 % </div>
</div>
</div>
```
And the css :
```
.meter-wrap{
position: relative;
}
.meter-value {
background-color: #489d41;
}
.meter-wrap, .meter-value, .meter-text {
width: 30px; height: 30px;
/* Attempt to round the corner : (indicators at the right of the screenshot)

}
.meter-wrap, .meter-value {
background: #bdbdbd top left no-repeat;
}
.meter-text {
position: absolute;
top:0; left:0;
padding-top: 2px;
color: #000;

1,767,952 | 1 | 1,774,992 | null | 0 | 217 | Suppose you have several functions y1 = f1(x), y2 = f2(x), etc. and you want to plot their graphs together on one plot.
Imagine now that for some reason it is easier to obtain the set of x for a given y; as in, there exists an oracle which given a y, will return all the x1, x2, etc. in increasing order for which y = f1(x1), y = f2(x2), etc.. In essence, it computes the inverse functions given a y. Suppose you uniformly sample in y, so you have a list of lists of x's. If you plot this data treating all the first x in each sublist as a function of y, and all the second x's in each sublist as a different function of y, etc., you obtain a plot like below.
In the above plot, the horizontal axis is y, and the vertical axis is x.
Note that the navy blue "curve" is the set of smallest x as a function of y (the set of points you would see looking up from underneath the plot), while the magenta curve is the set of second smallest x, etc. Obviously, the far left navy blue and magenta curves belong to a single function and should be connected. As you move towards the right, there are ambiguities and cross-overs. In those cases, it doesn't matter how the curves of the functions are connected, as long as it "looks" reasonable (there is a proper way, but I'll settle for this for now).
Now, the algorithm output should be samples of y as a function of x for each function, which when you plot it would look like:
(Apologies for the poor Paint edit job :)
I was thinking I proceed going one column at a time in the first pic and trying to match adjacent values based on slopes and how close they are to each other, but I'm not sure if there is a better way. Also, if this is a solved or documented problem, then I have no idea what to Google for, so any pointers would be helpful.
The actual application is in the computation of band structures of crystals, for anyone who is curious. The functions are the bands of the crystal, with the horizontal axis of the first plot being frequency, and the vertical axis is the k-vector. It turns out solving an eigenvalue problem for each frequency to get the eigenvalues (the k's) is easier in this case. It is fairly common to need to "prettify" and connect the resulting band structure plots, and I was wondering if there is an algorithmic way of doing it instead of having to do it by hand.

1,770,791 | 1 | 1,800,088 | null | 1 | 4,788 | Using standalone SWT Scrollbars is something of a hack (using [this workaround](https://stackoverflow.com/questions/1675514/swt-standalone-scrollbar-widget)), but it can be done. Here's a snippet:
```
ScrolledComposite scrolledComposite = new ScrolledComposite(
parent, SWT.V_SCROLL);
ScrollBar scrollbar = scrolledComposite.getVerticalBar();
Shell tip = new Shell(UserInterface.getShell(), SWT.ON_TOP
| SWT.NO_FOCUS | SWT.TOOL);
// ..stylize and fill the tooltip..
```
Now what I'm trying to do is monitor when the user is interacting with the scrollbar. In particular, I want to know when the user is dragging the scrollbar—and when it has been released—in order to display an Office 2007-style tooltip revealing which page the position of the scrollbar corresponds with.
Presently, I have the following code which displays the tooltip:
```
scrollbar.addSelectionListener(new SelectionListener() {
public void widgetDefaultSelected(SelectionEvent event) {}
public void widgetSelected(SelectionEvent event) {
tip.setVisible(true);
}
}
```
It would seem logical then to have the tooltip disappear when the mouse button is released:
```
scrollbar.addListener(SWT.MouseUp, new Listener() {
public void handleEvent(Event event) {
tip.setVisible(false);
}
});
```
However, neither `scrollbar` nor `scrolledComposite` seem to respond to the `SWT.MouseUp` event when the user interacts with the scrollbar.
I presently have a workaround that hides the tip after a timeout, but I'm not satisfied with this. Any insights would be most appreciated!

How can I take two 3D points and lock them to a single axis? For instance, so that both their z-axes are 0.
I have a set of 3D coordinates in a scene, representing a a box with a pyramid on it. I also have a camera, represented by another 3D coordinate. I subtract the camera coordinate from the scene coordinate and normalize it, returning a vector that points to the camera. I then do ray-plane intersection with a plane that is behind the camera point.
```
O + tD
```
Where O (origin) is the camera position, D is the direction from the scene point to the camera and t is time it takes for the ray to intersect the plane from the camera point.
If that doesn't make sense, here's a crude drawing:
I've searched far and wide, and as far as I can tell, this is called using a "pinhole camera".
The problem is not my camera rotation, I've eliminated that. The trouble is in translating the intersection point to barycentric (uv) coordinates.
The translation on the x-axis looks like this:
```
uaxis.x = -a_PlaneNormal.y;
uaxis.y = a_PlaneNormal.x;
uaxis.z = a_PlaneNormal.z;
point vaxis = uaxis.CopyCrossProduct(a_PlaneNormal);
point2d.x = intersection.DotProduct(uaxis);
point2d.y = intersection.DotProduct(vaxis);
return point2d;
```
While the translation on the z-axis looks like this:
```
uaxis.x = -a_PlaneNormal.z;
uaxis.y = a_PlaneNormal.y;
uaxis.z = a_PlaneNormal.x;
point vaxis = uaxis.CopyCrossProduct(a_PlaneNormal);
point2d.x = intersection.DotProduct(uaxis);
point2d.y = intersection.DotProduct(vaxis);
return point2d;
```
My question is: how can I turn a ray plane intersection point to barycentric coordinates on both the x and the z axis?

Second:
I have a portion of my database the looks like the following diagram:
I have contributors on the system, each write to many sources, and a source can have many working contributors. Users can subscribe to as many contributors as they like and as many sources as they like. Now, what I want to do is simply retrieve all the articles for certain user. These articles are either coming through a contributor or a source the user subscribes to. To make it easy, when a user subscribes to a source I simply copy all the sources contributors to the users_contributors table. One tricky piece, when I retrieve the user's articles I retrieve all the articles that he his contributors write, and all the articles that were published in the sources he follows where those articles doesn't have a valid contributor on the system. (I.E contributorID is null).
I created the following query:
```
Select Articles.ArticleID, Articles.ContributorId, Contributors.Name,
Sources.Name, Articles.ArticleTitle
From Articles
Inner Join Contributors On Articles.ContributorId = Contributors.ContributorId
Inner Join Sources On Articles.SourceId = Sources.SourceID
Where Articles.ContributorId in (
Select ContributorId from Users_Contributors
Where UserID = 3
)
OR (
Articles.SourceId in (
Select SourceId from Users_Sources
Where UserID = 3
)
and
Articles.ContributorId is null
)
```
The problem with the above query is that, it doesn't return any article with contributorID null. I understand this is because of the join on the contributors table. What should I do in such a case?
1. Should I consider denormalization?
2. What are the prober fields to index on each table for this query to run fast (Rowset returned are approximately 10000)?
3. I need to support paging on this query, will "With { }" clause be appropriate to me, or should I consider another strategy? Thanks in advance. Ps: I'm using SQL Server 2008

1,790,631 | 1 | 1,942,562 | null | 17 | 6,645 | On the Includes tab of the Paths and Symbols section of the Project Properties dialog in the Eclipse CDT, there is an "Export" button:
The best documentation I have found says that this "toggles whether the selected include path is exported or not." If I click it, it changes to "Unexport" and "[exp]" is appended to the selected include path.
What exactly does this do? What does it mean to "export an include path?"

1,791,041 | 1 | 1,791,356 | null | 3 | 2,803 | After the user goes through the Setup Wizard, and makes a few choices, the usual thing is to display the [VerifyReadyDlg](http://www.wixwiki.com/index.php?title=VerifyReadyDlg) to say "Are you ready to install?"
The built-in VerifyReadyDlg is static. It does not present a summary of the choices he made previously. I'd like to modify it so that it does.
How can I do that?

I don't believe I can modify the Control table in the MSI, because mods during the installation process are not allowed. I found [MsiViewModifyInsertTemporary](http://www.bing.com/search?q=msiviewmodifyinserttemporary&form=QBRE&qs=n), but I don't think that will work either. The relevant row in the Control table is already present, and it contains static data. I want to modify the data, just before VerifyReadyDlg is displayed.
