4,073,296 | 1 | 4,082,095 | null | 4 | 1,392 | I created a custom UserControl that functions much like a numbericUpDown but with various enhancements. For example, it can display fractions. However, this control does not scale as well as some of my other controls on my form, forcing my UI to look awkward.
I played around with the AutoScaleMode of both the control and it's parent control. Nothing seems to work, though setting the AutoScaleMode to None seems to have less impact than the other settings. I also tried manually to lessen the size of the control in relation to the dropdown next to it. It didn't work. I'm pretty much stuck and I don't know how to counter this.
Any suggestions?

```
local function Line (buf, x1, y1, x2, y2, color, pitch)
-- identify the first pixel
local n = x1 + y1 * pitch
-- // difference between starting and ending points
local dx = x2 - x1;
local dy = y2 - y1;
local m = dy / dx
local err = m - 1
if (dx > dy) then -- // dx is the major axis
local j = y1
local i = x1
while i < x2 do
buf.buffer[j * pitch + i] = color
if (err >= 0) then
i = i + 1
err = err - 1
end
j = j + 1
err = err + m
end
else -- // dy is the major axis
local j = x1
local i = y1
while i < y2 do
buf.buffer[i * pitch + j] = color
if (err >= 0) then
i = i + 1
err = err - 1
end
j = j + 1
err = err + m

do return end
end
```
Edit: Oh I just realized something. 0,0 is in the lower left-hand corner. So the function's sort of working, but it's overlapping and slanted.
Edit2:
Yeah, this whole thing's broken. I'm plugging numbers into Line() and getting all sort of results. Let me show you some.
Here's `Line (self.buffer, 0, 0, 23, 23, 0x00ffff, 24 * 2)`
And here's `Line (self.buffer, 0, 1, 23, 23, 0x00ffff, 24 * 2)`
Edit: Wow, doing `Line (self.buffer, 0, 24, 24, 24, 0x00ffff, 24 * 2)` uses way too much CPU time.
Edit: Here's another image using this algorithm. The yellow dots are starting points.
```
Line (self.buffer, 0, 0, 24, 24, 0xff0000, 24)
Line (self.buffer, 0, 12, 23, 23, 0x00ff00, 24)

4,074,017 | 1 | 4,074,825 | null | 2 | 5,061 | I've found the solution, it was more simple than I could have hoped. Thanks for your time. =) (Answered my own question with full solution)
My apologies that my post was not transparent enough.. I will try to iterate for a little more clarity. I am not simply trying to contain things and have the container resize without the contents resizing. I would just use a simple MovieClip for that.. . I'm trying to make a repeating background image for a container; thus far I'm able to draw my BitmapFill sprite to the size I want. (Which is the stage's height) but when the stage is resized, I want to re-size my container but have my containers BitmapFill crop or add more as the window is resized bigger or smaller. Allow me to illustrate what I mean:
I hope this clears up any confusion and helps with any straighter answers.
I've got a simple rectangle sprite that fills with a bitmap from the library and a simple resize handler function that detects when the window has been resized.
What I would like to do is have my rectangle resize to the height of the stage.stageHeight maintaining its bitmap fill, but the bitmap fill or any children within the sprite.
From what I've read, this is a little tricky because the sprite resizes in relation to what it contains.. or.. something like that.. I really don't know any more.. I saw one example where a person extended the sprite class but I don't know why or how..
in my library there is an image called 'pattern' and my code looks like this:
```
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.addEventListener(Event.RESIZE, resizeHandler, false, 0, true);
var bgData:pattern = new pattern(0,0);
var bg:Sprite = new Sprite();
bg.graphics.beginBitmapFill(bgData, null, true, false);
bg.graphics.drawRect( 0, 0, 80, stage.stageHeight);
bg.graphics.endFill();
addChild(bg);
function resizeHandler(e:Event=null):void
{
trace("dimensions are: " + stage.stageWidth + " x " + stage.stageHeight);
bg.height = stage.stageHeight; //simply makes the fill resize also
}
```

[Read/Write 'Extended' file properties (C#)](https://stackoverflow.com/questions/220097/read-write-extended-file-properties-c)
Does anyone know how to get the information contained in the tab of a File's properties window? Any .NET library I'm overlooking?
This is the window/information I'm talking about:
It seems like there would be a better way to access these data rather than having to employ various methods to extract metadata of various file types, since there's certainly some overlap on the categories of information available under this tab, even for different file types. But search as I might, I haven't come across anyone wanting to do this for any (or many) file types -- quite a few discussions on grabbing metadata for specific file types though.
Any suggestions you may have would be most welcome :)

Similar question have been asked ([This one](https://stackoverflow.com/questions/2982985/algorithm-to-zoom-into-mouseopengl) for example), but all the solutions i found used the
1. Translate to origin
2. Scale to zoom
3. Translate back
approach. While this works in principle, it leads to objects being clipped away on high zoom levels since they become bigger then the viewing volume is. A more elegant solution would be to modify the projection matrix for the zooming.
I tried to implement this, but only got a zoom to the center of the window working.
```
glGetIntegerv(GL_VIEWPORT, @fViewport);
//convert window coordinates of the mouse to gl's coordinates
zoomtoxgl := mouse.zoomtox;
zoomtoygl := (fviewport[3] - (mouse.zoomtoy));
//set up projection matrix
glMatrixMode(GL_PROJECTION);
glLoadidentiy;
left := -width / 2 * scale;
right := width / 2 * scale;
top := height / 2 * scale;
bottom := -height / 2 * scale;
glOrtho(left, right, bottom, top, near, far);
```
My questions are: Is it possible to perform a zoom on an arbitrary point using the projection matrix alone in an orthographic view, and if so, How can the zoom target position be factored into the projection matrix?
I changed my code to
```
zoomtoxgl := camera.zoomtox;
zoomtoygl := (fviewport[3] - camera.zoomtoy);
dx := zoomtoxgl-width/2;
dy := zoomtoygl-height/2;
a := width * 0.5 * scale;
b := width * 0.5 * scale;
c := height * 0.5 * scale;
d := height * 0.5 * scale;
left := - a - dx * scale;
right := +b - dx * scale;
bottom := -c - dy * scale;
top := d - dy * scale;
glOrtho(left, right, bottom, top, -10000.5, Camera.viewdepth);
```
which gave this result:
Instead of scaling around the cursor position, i can know shift the world origin to any screen location i wish. Nice to have, but not what i want.
Since i am stuck on this for quite some time now, I wonder : Can a zoom relative to an arbitrary screen position be generated just by modifying the projection matrix? Or will I have to modify my Modelview matrix after all?

4,076,091 | 1 | 6,643,208 | null | 4 | 2,177 | I have a very strange issue and I have no idea how to debug it. (Side note: I hate creating GUI's! Anyway... :)
I have been following [this](http://timheuer.com/blog/archive/2009/10/19/silverlight-toolkit-adds-drag-drop-support.aspx) guide to using drag 'n drop on Silverlight.
Right now, what I'm interested in is the reordering in a list.
If I follow the example from the site exactly, everything is fine. It works as expected.
Consider the following XAML:
```
<toolkit:ListBoxDragDropTarget AllowDrop="True">
<ListBox Width="200" Height="500" x:Name="FromBox" DisplayMemberPath="Label">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
</toolkit:ListBoxDragDropTarget>
```
aside from the DisplayMemberPath which is here "Label", this is the same as in the article I'm following.
In the code-behind I now do the following:
```
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
FromBox.ItemsSource = GetElements();
}
public static ObservableCollection<Element> GetElements()
{
ObservableCollection<Element> Elements = new ObservableCollection<Element>();
var Label = new Label();
Label.Label = "Label me";
Elements.Add(Label);
var IntegerBox = new IntegerBox();
IntegerBox.Label = "Størrelsen på en gennemsnits svale:";
IntegerBox.Description = "cm";
Elements.Add(IntegerBox);
var TextBox = new TextBox();
TextBox.Label = "QTTextBox";
Elements.Add(TextBox);
return Elements;
}
```
(Apologies for containing special Danish characters in this bit, but I thought it was better to show the exact code I'm using than editing it out)
As you can see, I return an ObservableCollection of Element's, each of which has a Label property (and they all inherit from the Element class, obviously).
To me, this ought to work the same as the code provided in the link.
But it doesn't. It's as if I can no longer drop items!?
This is how it looks in the article:
And this is how it looks with my elements:
Is there some demand on the kind of things that can be reordered? The article uses Person-objects, but these are ultra simple and do not implement any further interfaces. I'm also, as you can see, making sure to use an ObservableCollection with the right type. Is it just because it can't handle inheritance?!
... Or have I simply been stupid? :-)
Thanks in advance!
EDIT:
I've narrowed down the problem to having to do with inheritance.
The following code cannot be reordered either:
```
public class People
{
public static ObservableCollection<Person> GetListOfPeople()
{
ObservableCollection<Person> ppl = new ObservableCollection<Person>();
for (int i = 0; i < 15; i++)
{
if (i % 2 == 0)
{
SomePerson p = new SomePerson() { Firstname = "First " + i.ToString(), Lastname = "Last " + i.ToString() };
ppl.Add(p);
}
else
{
OtherPerson p = new OtherPerson() {Firstname = "First " + i.ToString(), Lastname = "Last " + i.ToString()};
ppl.Add(p);
}
}
return ppl;
}
}
public class Person
{
public string Firstname { get; set; }
public string Lastname { get; set; }
public string FullName
{
get
{
return string.Concat(Firstname, " ", Lastname);
}
}
}
public class SomePerson : Person
{
}
public class OtherPerson : Person
{
}
```
WTF?!
It seems you can only reorder elementes that have the type declared as the type-parameter on the ObservableCollection. Thus, if I declare it contains "Person" objects and mix in Person-objects rather than SomePerson and OtherPerson, I can move .

I'm using Local_resources to get my aspx files in Spanish and english.
If a use my aspx in the root of the website the Local_resources folder find the aproppiate resx for my aspx (because both have the same name). But if i put all my aspx into a folder created in the root directory, everything stop working:
as you can see i have a folder named "Inventario" and inside that folder i have Productos.aspx.
In App_LocalResources i have two files, one for spanish and one for english.
If i put Productos.aspx in the root directory they work fine, but i need them like in the image and like that is not working.
What should i do to the resx files to point to Inventario/Productos.aspx ?

I'm trying to write an algorithm that will detect the space between 'RF' and 'WOOLF in the image below.
I need something like Scanline for COLUMNS not rows.
My algorithm will be scanning each column for the presence of black pixels, if it finds any it will store '1', else it will store '0', so for example the image above might be:
000001111111111111111111100000000000000000000000011111111111111111111111111111111111111111111111111

How can i do that? How can i know which language is being used in the Website so i can use the aproppiate language in the ModeloInventarioLogica.cs class?

Now what I want is as follows: for each dialog in an app, I want to create a separate `UserControl` (not a full-blown `Form`) and then "host" it inside this generic dialog. To do so, I need to somehow make this dialog self-adjustable so that it would shrink or grow depending on the size of a control hosted inside it.

The condition however does not fulfill its purpose as the same rows are selected multiple times.
The actual aim here is to retrieve the whole cluster of connections to which the selected user (in the example user b) belongs.
I tried to modify the query the following way:
```

(SELECT calling_party CALLING, called_party CALLED, link_strength FROM dbo.monthly_connections_test WHERE link_strength > 0.1),
related_users1 AS
(
SELECT c.CALLING, c.CALLED, c.link_strength, CONVERT(varchar(max), '.' + c.CALLING + '.' + c.CALLED + '.') path from combined_users c where CALLING = 'a1'

from combined_users c
join related_users1 r
ON (c.CALLING = r.CALLED) and CHARINDEX(c.CALLING + '.' + c.CALLED + '.', r.path)= 0
),
related_users2 AS
(
SELECT c.CALLING, c.CALLED, c.link_strength, CONVERT(varchar(max), '.' + c.CALLING + '.' + c.CALLED + '.') path from combined_users c where CALLED = 'a1'
UNION ALL
SELECT c.CALLING, c.CALLED, c.link_strength,
convert(varchar(max),r.path + c.CALLING + '.') path
from combined_users c
join related_users2 r
ON c.CALLED = r.CALLING and CHARINDEX('.' + c.CALLING + '.' + c.CALLED, r.path)= 0
)
SELECT CALLING, CALLED, link_strength, path FROM
(SELECT CALLING, CALLED, link_strength, path FROM related_users1 UNION SELECT CALLING, CALLED, link_strength, path FROM related_users2) r OPTION (MAXRECURSION 30000)
```
To test the query I created the cluster below:
The query above returned the following table:
```
a1 a2 1.0000000 .a1.a2.
a11 a13 1.0000000 .a12.a1.a13.a11.
a12 a1 1.0000000 .a12.a1.
a13 a12 1.0000000 .a12.a1.a13.
a14 a13 1.0000000 .a12.a1.a13.a14.
a15 a14 1.0000000 .a12.a1.a13.a14.a15.
a2 a10 1.0000000 .a1.a2.a10.
a2 a3 1.0000000 .a1.a2.a3.

a3 a6 1.0000000 .a1.a2.a3.a6.
a4 a8 1.0000000 .a1.a2.a3.a4.a8.
a4 a9 1.0000000 .a1.a2.a3.a4.a9.
```
The query obviously returns connections toward the selected node and the connections in the opposite direction. The problem is the change of direction: for example the connections a7, a4 and a11, a10 are not selected because the direction is changed (relative to starting node).
Does anyone know how to modify the query in order to include all connections?

I'm using carrierwave to upload images to S3.
My gallery page ('show' action) displays thumbnails for each image in that gallery.

This tends to although I've noticed it happening with images I've not clicked on in over an hour or so too. The problem goes away if I click on the thumbnail again immediately after the failure.... I never have any trouble with the thumbnails, they all load fine. It seems as though the large (original) version of the image is not getting downloaded on the first attempt.

4,081,811 | 1 | 4,082,220 | null | 158 | 59,302 | I'm using [_viewstart.cshtml to automagically assign the same Razor Layout](http://weblogs.asp.net/scottgu/archive/2010/10/22/asp-net-mvc-3-layouts.aspx) to my views.
It's a dead simple file in the root of my Views folder that looks like this:
```
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
```
This is more DRY than adding the @Layout directive to every single view.
However, this poses a problem for Razor views, because they run the contents of _viewstart.cshtml and therefore incorrectly assign themselves a layout, which makes them, um, no longer partial.
Here's a hypothetical project, showing the _viewstart.cshtml file, the shared _layout.shtml file, and a partial view ("AnonBar.cshtml").
Currently, the way that I'm getting around this is by adding the following line to every partial view:
```
@{
Layout = "";
}
```
This seems like the wrong way to denote a view as a partial in Razor. (Note that unlike the web forms view engine, the file extension is the same for partial views.)
Other options I considered but that are even worse:
- -
Is this something that is still being fleshed out by the Razor view engine team, or am I missing a fundamental concept?

4,083,542 | 1 | 4,085,108 | null | 0 | 224 | Previously, we have a legacy system, which we are using C++ code to generate reports in Text file and Excel file. However, it is a pain to perform manual coding to perform all the raw data processing and report format rendering.
Recently, we had success to migrate all the raw data into SQL database.
To avoid writing manual code, we decide to evaluate the following tool.
1. JasperReports - Able to help us perform report format rendering?
2. OpenReport - Provides us web access to the generated report?
Currently, our raw data looks something like :
Based on the demo provided by OpenReport and JasperReports, I believe we can generate a report like
```
Summary Report for Lot 2
------------------------
Measurement Type Value
----------------------------------
Lead 1 Average 1.30
Lead 1 StdDev 0.16
.
.
Lead 2 Average 2.08
Lead 2 StdDev 0.55
```
However, this is a little far than what we want. What we want is to able
1. Take the multiple rows of Lead 1, 2, 3... under Average category, and have a logic code function to recalculate them into a single Lead row.
2. Do the same for rest of the statistics like StdDev...
3. Have a report format like :
---
```
Summary Report for Lot 2
------------------------
Measurement Average StdDev
----------------------------------
Lead 2.33 1.23
```
---
So far for the demo that I had seen, most of them are just `1 to 1 mapping` from raw database to report. In the middle of `1 to 1 mapping`, I know there can be some simple SQL statement for filtering and manipulation. I haven't seen an example which can perform a `sophisticated` processing.
The reason I call it `sophisticated`, as in C++ code, we require to perform std::string processing, making use of std::vector, std::map data structure and arithmetic operation. I am doubt SQL statement can perform similar.
Based on my listed requirement, is it possible that I can use available reporting tool in the market to generate report? Or we need to develop our own middle-ware to perform such task? (Perl/ Python/ ... whatever)

I tend to use the first approach, although I am not too sure why. I guess maybe it is because there may be some concrete implementation of IBonus that might not need a dependency at all, while the second approach is tieing me to something. A stub/mock class, for example.

4,083,882 | 1 | 4,084,164 | null | 1 | 1,966 | This post is actually divided in two questions:
## Which kinds of associations classes/interfaces usually have?
I'd say there are at least 3 kinds of dependencies:
- - `class A``class B``class A``class B`- `class A``class B``class B``class A`
Are these the only kind of associations between classes? Are my interpretations of what they mean correct?
## Which kind of dependencies are of our interest to show on UML diagrams (mostly class/package diagrams)?
Up until now, I've mostly only put in class diagrams arrows depicting dependencies associations. But now that I think of it, most of the time I look at class diagrams, I'll find something along the lines of
where only `Inherits` and `Uses` associations are shown. But those `Uses` in the class diagram aren't really the same kind of `Uses` I've defined above. They are just a way of telling you there's a getter on a class of a type that's not a primitive.
I guess that if I had to look to some system's documentation I'd like to know how different classes in the system depend on each other. I'd definetely like to have some sort of `Dependency Graph` to look at.
Would it better to restrict class diagrams to `Inherits/Uses` associations and then have other diagram/graph that shows `Depends/Uses` associations?
How do you prefer it, and why?
Thanks

4,084,013 | 1 | 4,084,475 | null | 18 | 17,558 | So one of my coworkers accidentally made a merge that actually only kept one side of the tree. So he started a merge, deleted all the changes introduced by the merge, and then committed the merge.
Here is a simple test case I did on a test repo. This repo has three branches. idx is the topic branch that was accidentally merged, and master is the mainline. dev is just a test of how revert -m works so you can ignore it.
What I want to do is revert the faulty merge. So from master I try to run `git revert -m 1 <sha1sum of faulty merge>` but then git responds with:
```
# On branch master
nothing to commit (working directory clean)
```
So it doesn't actually create a revert commit that undoes the merge. I believe that this happens because the merge didn't actually contain any real changes.
Is this a git bug, or am I missing something?

Does anyone know why this happens and where I'm going wrong?
I've read about using [ASIHTTPPost](http://allseeing-i.com/ASIHTTPRequest/) instead but I can't get the demo to run in iOS4 :(
Thanks
EDIT:
I've just used to [CharlesProxy](http://www.charlesproxy.com/) to sniff out what's happening when I call from the iPhone (Simulator) and this is what it gave me:
(This also happens in my working windows client).
I've just ran this on my windows client and the only thing that is different is the Request and Response text which is encrypted. Am I missing something in order to use a secure HTTP connection to do this?
NEW EDIT:
This works with a non-HTTPS request such as:
[http://maps.googleapis.com/maps/api/geocode/json?address=UK&sensor=true](http://maps.googleapis.com/maps/api/geocode/json?address=UK&sensor=true). So I guess the problem is getting the iPhone to send the POST properly over SSL?
I am also using these methods:
```
- (void) connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
forAuthenticationChallenge:challenge];
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
- (void) connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust])
{
return YES;
}
}
```
This allows me to get this far. If I don't use them I get an error sent back saying:

my rounded rectangle's corners have an ellipseWidth and ellipseHeight of 40. since they are equal i'm confident in assuming that the curvature of each corner begins at minus half of the corner size. so instead of drawing my stroke all the way to the corner i will end the stroke at 20 pixels before the corner and curve it to 20 pixels after the corner. clear as mud?
interestingly, if i draw my stroke all the way around the rounded rectangle following the same code, the stroke is only inaccurately drawn around these two corners. additionally, if the stroke is increased to 2, the gaps are no longer visible.
```
//Rounded Rectangle
var rectWidth:uint = 300;
var rectHeight:uint = 100;
var rectCorners:uint = 40;
var rect:Shape = new Shape();
rect.graphics.beginFill(0);
rect.graphics.drawRoundRect(-rectWidth / 2, -rectHeight / 2, rectWidth, rectHeight, rectCorners, rectCorners);
//Stroke
var stroke:Shape = new Shape();
stroke.graphics.lineStyle(1, 0xFF0000, 1, true, "normal", "none", "miter", 3);
//Stroke Around Top Right Corner
stroke.graphics.moveTo(rect.x + rectWidth / 2 - rectCorners / 2, rect.y - rectHeight / 2);
stroke.graphics.curveTo(rect.x + rectWidth / 2, rect.y - rectHeight / 2, rect.x + rectWidth / 2, rect.y - rectHeight / 2 + rectCorners / 2);
//Stroke Around Bottom Right Corner
stroke.graphics.lineTo(rect.x + rectWidth / 2, rect.y + rectHeight / 2 - rectCorners / 2);

//Add To Display List
addChild(rect);
addChild(stroke);
```

## UPDATE
the larger the round rect and its corners become, the more displaced my stroke becomes. i am no longer confident that my curvature/anchor points for my curveTo() functions are correct. any thoughts?

4,087,919 | 1 | 4,092,160 | null | 202 | 15,369 | After my previous question on [finding toes within each paw](https://stackoverflow.com/questions/3684484), I started loading up other measurements to see how it would hold up. Unfortunately, I quickly ran into a problem with one of the preceding steps: recognizing the paws.
You see, my proof of concept basically took the maximal pressure of each sensor over time and would start looking for the sum of each row, until it finds on that != 0.0. Then it does the same for the columns and as soon as it finds more than 2 rows with that are zero again. It stores the minimal and maximal row and column values to some index.
As you can see in the figure, this works quite well in most cases. However, there are a lot of downsides to this approach (other than being very primitive):
- Humans can have 'hollow feet' which means there are several empty rows within the footprint itself. Since I feared this could happen with (large) dogs too, I waited for at least 2 or 3 empty rows before cutting off the paw. This creates a problem if another contact made in a different column before it reaches several empty rows, thus expanding the area. I figure I could compare the columns and see if they exceed a certain value, they must be separate paws.- The problem gets worse when the dog is very small or walks at a higher pace. What happens is that the front paw's toes are still making contact, while the hind paw's toes just start to make contact within the same area as the front paw!With my simple script, it won't be able to split these two, because it would have to determine which frames of that area belong to which paw, while currently I would only have to look at the maximal values over all frames.
Examples of where it starts going wrong:
(after which I'll get to the problem of deciding which paw it is!).
I've been tinkering to get Joe's (awesome!) answer implemented, but I'm having difficulties extracting the actual paw data from my files.
The coded_paws shows me all the different paws, when applied to the maximal pressure image (see above). However, the solution goes over each frame (to separate overlapping paws) and sets the four Rectangle attributes, such as coordinates or height/width.
I can't figure out how to take these attributes and store them in some variable that I can apply to the measurement data. Since I need to know for each paw, what its location is during which frames and couple this to which paw it is (front/hind, left/right).
I have the measurements I used in the question setup in my public Dropbox folder ([example 1](http://dl.dropbox.com/u/5207386/Examples/Normal%20measurement), [example 2](http://dl.dropbox.com/u/5207386/Examples/Grouped%20up%20paws), [example 3](http://dl.dropbox.com/u/5207386/Examples/Overlapping%20paws)).

4,088,066 | 1 | 4,088,949 | null | 0 | 686 | Right, so I'm new to Castle and I'm trying to figure out how far I need to go to wire up a service. Below is a sample of the classes I'm working with and where they sit in the world I've created.
What I'm trying to accomplish it to properly wire up Castle so that I can call the TemplateEmailViaSalesforce class to do the work, and have the dependent classes wired up via DI from Castle. But I'm unsure of how far I have to go when registering components. Below is my first attempt (I'm registering via code as a trial, and this is a mashup of a couple methods to create the container)
```
IWindsorContainer container = new WindsorContainer();
container.AddFacility<FactorySupportFacility>();
// add the DAL mapper factory
container.AddComponent<ITemplateMapperFactory>();
// individual mappers
container.Register(Component.For<ICSGEmailTemplateMapper>().UsingFactory((ITemplateMapperFactory f) => f.CSGEMailTemplate));
container.Register(Component.For<IUserMapper>().UsingFactory((ITemplateMapperFactory f) => f.User));
container.Register(Component.For<IGoupMapper>().UsingFactory((ITemplateMapperFactory f) => f.Group));
container.Register(Component.For<IAccountTeamMapper>().UsingFactory((ITemplateMapperFactory f) => f.AccountTeam));
container.Register(Component.For<ISalesTeamMapper>().UsingFactory((ITemplateMapperFactory f) => f.SalesTeam));
container.Register(Component.For<ICSGFormulaMapper>().UsingFactory((ITemplateMapperFactory f) => f.CSGFormula));
container.Register(Component.For<ISFObjectDefinitionMapper>().UsingFactory((ITemplateMapperFactory f) => f.SFDCObjectDefinition));
container.Register(Component.For<ISFObjectValueMapper>().UsingFactory((ITemplateMapperFactory f) => f.SFDCObjectValue));
container.Register(Component.For<ISalesforceTemplateMapper>().UsingFactory((ITemplateMapperFactory f) => f.Template));
container.Register(Component.For<IRecipientMapper>().UsingFactory((ITemplateMapperFactory f) => f.Recipient));
// BLL stuff (domain components)...general
container.AddComponent<CSGEmailTemplateRepository, CSGEmailTemplateRepository>();
container.AddComponent<RecipientRepository, RecipientRepository>();
container.AddComponent<SFObjectDefinitionRepository, SFObjectDefinitionRepository>();
container.AddComponent<SFObjectValueRepository, SFObjectValueRepository>();
container.AddComponent<TemplateRepository, TemplateRepository>();
container.AddComponent<UserRepository, UserRepository>();
container.AddComponent<ITemplateService, TemplateService>();
// specific for this action
container.AddComponent<TemplateEmailerViaSalesforce>();
container.AddComponent<TemplateParse>();
// Aspects
container.AddComponent<TraceAspect>();
```
Now, I get an error later at: `container.Resolve<TemplateEmailerViaSalesforce>();`
```
AssemblerTests.ShouldCreateTemplateService : FailedTest method Tests.AssemblerTests.ShouldCreateTemplateService threw exception: Castle.MicroKernel.Facilities.FacilityException: You have specified a factory ('Castle.MicroKernel.Registration.GenericFactory`1[[CSG.Salesforce.TemplateEmailer.DAL.Access.IUserMapper, CSG.Salesforce.TemplateEmailer.DAL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' - method to be called: Create) for the component 'CSG.Salesforce.TemplateEmailer.DAL.Access.IUserMapper' CSG.Salesforce.TemplateEmailer.DAL.Access.IUserMapper that failed during invoke. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Castle.MicroKernel.ComponentRegistrationException: Type CSG.Salesforce.TemplateEmailer.DAL.ITemplateMapperFactory is abstract.
```
The failure seems to be with IUserMapper which is defined as `class UserMapper:BaseSalesforceMapper<UserData>,IUserMapper`
The other mappers work but I get an error that not all dependencies were satisfied, which I need the IUserMapper registration to satisfy fully.
How far down the rabbit hole do I have to go to get this wired? At this point I'm looking though the BLL into the DAL and into a base class that app mappers are built from and it doesn't seem right. I'm struggling with figuring out what I have to get registered and what will be implicitly done with DI by Castle itself.
Any help at all would be appreciated. Thanks.`enter code here`

4,089,717 | 1 | null | null | 4 | 11,085 | Can anyone explain why Nimbius treats the setOpaque() differently than other java LaF's. Its breaking my code because components that are normally transparent no longer are.
EDIT: The problem seems to only deal with JTextAreas (which is what I need) or similar components.
EDIT EDIT: This is a screen of the actual application. When applying trashgod's solution, the background still does not show through.
EDIT EDIT EDIT: I tried trashgod's suggestion to override the paint(). I toiled with this for hours, and could not get it to work. I was able to get the background to show through, but the JinternalFrame was unable to be moved, resized, and have its text selected. Calling super.paint(g) failed to solve the solution. Is there an easy way to do this that I might be missing?
Ive taken a new approach to this. Inside the JInternalFrame is a JLayeredPane.
Layer 0 - JLabel
Layer 1 - JTextArea
When the JInternalFrame is moved or resized:
1. Makes itself invisible
2. Takes a screen shot of where it was in the container its contained in
3. Paints the JLabel with the image it took
4. Makes itself visible again.
Since I could not get the JInternalFrame to be transparent at all. I simulated its transpaency. The only issue is, there is a lot of overhead associated with this. Any thoughts?

Next I'm using Libnoise to a heightmap cube using 3D Perlian noise. I am able to generate a seamless cubmap. I have checked this in photoshop and though I had to rotate the heightmap images to get them to fit in the net I think they are the correct orientation.
I have tried getting the perlin value for the co ordinates before they are mapped to a sphere and after, but I am unable to make the edges match up:
At the moment I am creating geometry between -0.8 and +0.8 and then adding 0.2 * heightmap percentage.
Either I am making use of the heightmap data wrongly or the heightmaps are not orientated correctly (I suspect it is a little of both).

4,090,139 | 1 | 4,100,576 | null | 2 | 103 | I have a host application that controls various factory classes which produce implementations of a common data contract. Also, all the factories derive from a particular factory contract. The factories may need particular implementations of the data contract to generate their own objects... so the host can generically pass data via a function in the factory contract that has one argument of the data contract type. The factories then try to cast it to the type they are interested in... ignoring it if it doesn't match. This all works ok so far.
I wanted to extend this to allow users to create add-in factories using the .NET add-in framework, but I'm concerned about the isolation boundaries... For instance, if a factory produces an IData instance, can another factory cast objects produced by the add-in to the shared concrete implementation type? It looks like the need for adaptors in the add-in pipeline may screw this up?
For instance, in the diagram below, the concrete class DataA would be shared between PluginA and PluginB, and the concrete class DataB would be shared between PluginB and PluginC.
---
So far I only knew about the System.Addin functionality for creating add-ins... and the older methods involving direct reflection. I've just discovered MEF, which supposedly doesn't concern itself with the isolation boundaries that are core to the System.Addin stuff. Does anyone with experience with MEF know how this might impact my scenario?

Implement a function that searches for a null point of the sinus function in a interval between a and b. The search-interval[lower limit, upper limit] should be halved until lower limit and upper limit are less then 0.0001 away from each other.
1. Find a condition to decide in which halved interval the search has to be continued. So after cutting the interval into two intervals we have to choose one to get on with our search.
2. We assume that there is just one zero point in the interval between a and b.
I am struggling with point 1. I already had some questions on that topic that helped me a lot but now I need to implement it in java but it is not working yet.
Here is my code so far:
```
private static double nullstelle(double a, double b){
double middle = (a + b)/2;
double result = middle;
if(Math.abs(a-b) > 0.0001){
double sin = Math.sin(middle);
if(sin > 0){
result = nullstelle(a, middle);
}else{
result = nullstelle(middle, b);
}
}
return result;
}
```
I tried to implement using recursion but maybe an other way would be better, I don't know.

This works mostly well, but for some avatars the initial download fails (I suppose it times out) and you don't see the lower part of the player picture:

And my even bigger problem is, that I can't pass variables like $img or $cached into the callback or I can't set a $length variable in the callback on a STREAM_NOTIFY_FILE_SIZE_IS event and then compare it with filesize($cached) in the main script (I could detect the mismatch and delete the file):
```

Does anybody have a solution for my problem?
I've looked at the PHP curl library, but don't see how could it help me here.

I don't use any file locking in my script: it's ok for a read from cache to return an incomplete file (because it is still being downloaded) once in a while. But I want to keep my cache free of any partially downloaded images. Also if you look at my script I use "xb" which should prevent from several scripts writing into 1 file, so this simultaneous writing is not a problem here.

4,090,329 | 1 | null | null | 2 | 97 | I'm trying to implement a multiline textbox on a website. The textbox should offer a kind of autocompletion while the user is typing. The autocompletion should work similar to what is known as 'Intellisense' in ms visual studio (see screenshot below) and display the autocompletion selection (the list containing "bar", and "foo_bar") just below the textcursor.
I have started with a simple html textarea. I have found several jQuery-Plugins that help me in manipulating the textarea but one very basic problem remains.
How can I know where to position the autocompletion selection (the list containing "bar", and "foo_bar" in the screenshot)?
What html-element,text-editor,technique or plugin could help me to position the autocompletion selection right below the text cursor?
Thanks a lot

4,090,734 | 1 | null | null | 2 | 15,061 | I'm creating an inventory system with Ruby on Rails as the application server and having java clients as the frontend.
Part of the project mandates that we create an integrated class diagram (a class diagram that includes all classes and shows the relationships). The way the class has been designed and what we've been taught before was to use the (BCE) pattern to create appropriate classes, however, since we're using Rails which uses an MVC architecture, they directly conflict since there is not a 1:1 correlation between the two patterns, especially considering that the 'views' in our case is just XML, so there will be no class diagram for the views and a class shares the of the controller and the of a view.
So far, our class diagram just features the Rails related classes (since the client classes are mostly just UI). Here is the result of what we've done so far (ignore the fact that we have a million getters and setters -- it's a requirement for the project that we won't actually be implementing in that way; we'll use `attr_accessor`):
So, are we on the right track? Anything to add/edit/move? How exactly do we model correctly the built in ActiveRecord validator methods that we'll be using (such as `validates_numericality_of :price`)?
Any help is greatly appreciated! Thanks.

Obviously, there is some issue with my implementation. The above code returns:
> Original image ... Black:21 White:4After learning the network thinks ...
Black:25 White:0
It does the same thing if I try to use larger training set (I'm testing just 25 pixels from the image above for testing purposes). It returns that all pixels should be black after learning.
Now, if I use a manual training set like this instead:
```
trainingInputs = [
[0.0,0.0],
[1.0,0.0],
[2.0,0.0],
[0.0,1.0],
[1.0,1.0],
[2.0,1.0],
[0.0,2.0],
[1.0,2.0],
[2.0,2.0]
]
trainingOutputs = [
[0.0],
[1.0],
[1.0],
[0.0],
[1.0],
[0.0],
[0.0],
[0.0],
[1.0]
]
#------------------------------ let's train
for i in range(500):
for j in range(len(trainingOutputs)):
network.train(trainingInputs[j], trainingOutputs[j])
network.learn()
for w in network.weights:
w.delta = 0.0
#------------------------------ let's check
for inputs in trainingInputs:
print network.calculateSingleOutput(inputs)
```
The output is for example:
```
0.0330125791296 # this should be 0, OK
0.953539182136 # this should be 1, OK
0.971854575477 # this should be 1, OK
0.00046146137467 # this should be 0, OK
0.896699762781 # this should be 1, OK
0.112909223162 # this should be 0, OK
0.00034058462280 # this should be 0, OK
0.0929886299643 # this should be 0, OK
0.940489647869 # this should be 1, OK
```
In other words the network guessed all pixels right (both black and white). Why does it say all pixels should be black if I use actual pixels from the image instead of hard coded training set like the above?
I tried changing the amount of neurons in the hidden layers (up to 100 neurons) with no success.
This is a homework.
This is also a continuation of my [previous question](https://stackoverflow.com/questions/3988238/help-me-with-my-backprop-implementation-in-python) about backprop.

4,093,139 | 1 | 4,102,354 | null | 1 | 1,276 | I have this code to get the caller of my function's file name, line number, and function. It seems to be leaking frames though and I don't understand why. Is this just throwing me off and my leak must be elsewhere?
```
rv = "(unknown file)", 0, "(unknown function)"
for f in inspect.stack()[1:]:
if __file__ in f:
continue
else:
rv = f[1:4]
break
return rv
```
I'm not saving a reference to the frame anywhere. But it's definitely frames that are leaking:
:
My frames are definitely being leaked. I did the suggestion about gc.set_debug() and frames are very slowly going into the gc.garbage list. Not even close to how many are being created though as show in show_most_common_types(). I have a question about scope though, in the above, doesn't `f` go out of scope after the for loop? Because I just tried this:
```
for f in range(20):
l = 1
print f
```
and it printed 19. So could it be my `f` in the for loop leaking? This is a reference graph of a frame reference that was in my gc.garbage list:
:
It looks like the inspect module itself is holding references to the frames. This is an objectgraph of a backreference from a live frame, not one on the garbage list.
Link [here](https://i.stack.imgur.com/UfjQ4.png) because it's too wide.
Is there a way to clear the inspect module? Where the hell are these frames being saved =\

Original Image:

The original image is 100x100 pixels, made in paint and saved as a 24 bit bitmap.
Here is my opengl initialization code:
```
_hdc = GetDC(_hwnd);

ZeroMemory( &pfd, sizeof( pfd ) );
pfd.nSize = sizeof( pfd );
pfd.nVersion = 1;
pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER;
pfd.iPixelType = PFD_TYPE_RGBA;
pfd.cColorBits = 24;
pfd.cDepthBits = 16;
pfd.iLayerType = PFD_MAIN_PLANE;
int iFormat = ChoosePixelFormat( _hdc, &pfd );
SetPixelFormat( _hdc, iFormat, &pfd );
_hrc = wglCreateContext(_hdc);
wglMakeCurrent(_hdc, _hrc);
GLHelper* helper = GLHelper::get();
helper->initialize(_hwnd, _hdc, _hrc);

_settings.sceneWidth, _settings.sceneHeight);

I use the library FreeImage, which looks pretty well tested and widely used.
Here is the image loading code:
```
//image format
FREE_IMAGE_FORMAT fif = FIF_UNKNOWN;
//pointer to the image, once loaded
FIBITMAP *dib(0);
//pointer to the image data
BYTE* bits(0);
//image width and height
unsigned int width(0), height(0);
//OpenGL's image ID to map to
GLuint gl_texID;
//check the file signature and deduce its format
fif = FreeImage_GetFileType(filename, 0);
//if still unknown, try to guess the file format from the file extension
if(fif == FIF_UNKNOWN)
fif = FreeImage_GetFIFFromFilename(filename);
//if still unkown, return failure
if(fif == FIF_UNKNOWN)
return false;
//check that the plugin has reading capabilities and load the file
if(FreeImage_FIFSupportsReading(fif))
dib = FreeImage_Load(fif, filename);
//if the image failed to load, return failure
if(!dib)
return false;
//retrieve the image data
bits = FreeImage_GetBits(dib);
//get the image width and height
width = FreeImage_GetWidth(dib);
height = FreeImage_GetHeight(dib);
//if this somehow one of these failed (they shouldn't), return failure
if((bits == 0) || (width == 0) || (height == 0))
return false;
//if this texture ID is in use, unload the current texture
if(m_texID.find(texID) != m_texID.end())
glDeleteTextures(1, &(m_texID[texID]));
//generate an OpenGL texture ID for this texture
glGenTextures(1, &gl_texID);
//store the texture ID mapping
m_texID[texID] = gl_texID;
//bind to the new texture ID
glBindTexture(GL_TEXTURE_2D, gl_texID);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
//store the texture data for OpenGL use
glTexImage2D(GL_TEXTURE_2D, level, internal_format, width, height,

4,093,640 | 1 | 4,094,772 | null | 1 | 601 | Is there a standard way to add a to a , in which I can add a to make the selected option the default one?
Similar to the context menu that comes up when choosing the default home screen for example.
From the Api docs for ContextMenu I see that you can set a header view, but not a footer view. Also the `setCheckable` / `setGroupCheckable` methods don't seem to help much here.
Does this need to be done via a custom (alert) dialog? I would be wondering if nobody has yet developed such a component yet in case it's not possible through the standard SDK api. Any standalone open source component out there (beside the Android source itself)?

4,093,685 | 1 | 4,095,728 | null | 1 | 5,195 | I want a simple filter form, and a table below it. When the user changes the option on the select form, the table automaticaly changes. I think thats done with ahah.
I want this (some things can change, like the fieldset containing the table, and other stuff):
But working.. of course..
I'm currently showing that page using one function. It's a complete mess and something like "NEVER DO THIS", but i'm researching and trying some stuff as i'm a drupal learner.
This is the relevant code:
```
form = array();
ahah_helper_register($form, $form_state);
//query here, build $options for the select
$form['listar_veics'] = array(
'#type' => 'fieldset',
'#prefix' => '<div id="listar-veics-wrapper">',
'#suffix' => '</div>',
'#tree' => TRUE,
);
if (!isset($form_state['values']['listar_veics']['filial']))
$choice = 1;
else
$choice = $form_state['values']['listar_veics']['filial'];
$form['listar_veics']['filial'] = array(
'#type' => 'select',
'#title' => "Listar veículos da filial",
'#options' => $filiais,
'#default_value' => $choice,
'#ahah' => array(
'event' => 'change',
'path' => ahah_helper_path(array('listar_veics')),
'wrapper' => 'listar-veics-wrapper',
'method' => 'replace',
),
);
//query for the rows i wanna show
//building $data array, the rows array
//building $header, as an array of strings
$table = theme_table($header, $data);
$page = drupal_render($form);
$page .= $table;
return $page;
```
So in this code, drupal will only replace the form itself, when i change the option on the select, it shows the new value on the select, but the table isnt rendered again thus not changing.
Thanks, apreciate every suggestion.
