2,589,948 | 1 | 2,593,883 | null | 6 | 6,011 | When hosting WPF user controls within a WinForms MDI app there is a drawing issue when you have multiple forms that overlap each other that causes very distinct visual artifacts. These artifacts are mostly visible after dragging one child form over another one that also hosts WPF content or by allowing the edges of the child form to be clipped by the main MDI parent when dragging it around. After the drag and drop of the child form is completed the artifacts stay around generally but I've found that setting focus to a different application's window and then refocusing back on to my application window that it is redrawn and all is good again until the child forms are moved once again. Please see the image below which demonstrates the problem.
Those at Microsoft insist that the WinForms MDI is already a sufficient solution for MDI and doesn't need reinventing in WPF although I find it hard to believe they tried creating a WPF app this way because of the obvious shortcomings.
A few extra notes that I left out is that if I create these Forms without setting the MdiParent they are created as regular forms and this issue doesn't happen. This issue seems unique to the WinForms MDI scenario. Also I've currently running on Windows 7 Enterprise and I'm aware the results may be quite different on Windows XP but I haven't been able to test this.
I've found a few other related resources on this issue that I thought I should share.

2,590,470 | 1 | 2,651,851 | null | 6 | 2,007 | I have a CATiledLayer into which I render content in the following method
```
- (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx
```
I used the QuartzDemo code to draw a pattern. This works very well until I apply a rotation transform to the layer's parentLayer (a UIView):
rotated:
These zigzag artefacts become worse when I start drawing lines and texts into the CATiledLayer.
I applied the transform as follows (I also tried using an affine transform on the view itself):
```
self.containerView.layer.transform = CATransform3DMakeRotation(angleRadians, 0.0f, 0.0f, 1.0f);
```
I transform the containerView rather than the layer itself, as I have several layers in that view that I would like to rotate at the same time without changing the relative positions.
I did not have problems when rotating UIImageViews in the past.
Is there a way that I can rotate the CATiledLayer without these problems?
Any help would be greatly appreciated.
Yours,
Felix

2,591,694 | 1 | 2,592,032 | null | 2 | 919 | I am rendering textured quads from an orthographic perspective and would like to simulate 'depth' by modifying UVs and the vertex positions of the quads four points (top left, top right, bottom left, bottom right).
I've found if I make the top left and bottom right corners y position be the same I don't get a linear 'skew' but rather a warped one where the texture covering the top triangle (which makes up the quad) seems to get squashed while the bottom triangles texture looks normal.
I can change UVs, any of the four points on the quad (but only in 2D space, it's orthographic projection anyway so 3D space won't matter much). So basically I'm trying to simulate perspective on a two dimensional quad in orthographic projection, any ideas? Is it even mathematically possible/feasible?
ideally what I'd like is a situation where I can set an x/y rotation as well as a virtual z 'position' (which simulates z depth) through a function and see it internally calclate the positions/uvs to create the 3D effect. It seems like this should all be mathematical where a set of 2D transforms can be applied to each corner of the quad to simulate depth, I just don't know how to make it happen. I'd guess it requires trigonometry or something, I'm trying to crunch the math but not making much progress.
here's what I mean:
Top left is just the card, center is the card with a y rotation of X degrees and right most is a card with an x and y rotation of different degrees.

I was successfully able to print my monochrome bitmap to my printer, however there is a large black stripe along the right of the image when the item prints.
Here is the original
(Scanned in)What the printer printed
Code to generate binary blob
```
Rectangle rect = new Rectangle(0, 0, Bitmap.Width, Bitmap.Height);
System.Drawing.Imaging.BitmapData bmpData = null;
byte[] bitVaues = null;
int stride = 0;
try
{
bmpData = Bitmap.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadOnly, Bitmap.PixelFormat);
IntPtr ptr = bmpData.Scan0;
stride = bmpData.Stride;
int bytes = bmpData.Stride * Bitmap.Height;
bitVaues = new byte[bytes];
System.Runtime.InteropServices.Marshal.Copy(ptr, bitVaues, 0, bytes);
}
finally
{
if (bmpData != null)
Bitmap.UnlockBits(bmpData);
}
string str = String.Format("GW{0},{1},{2},{3},", X, Y, stride, Bitmap.Height);
byte[] ascii = Encoding.ASCII.GetBytes(str);
byte[] buffer = new byte[ascii.Length + bitVaues.Length + 1];
Buffer.BlockCopy(ascii, 0, buffer, 0, ascii.Length);
Buffer.BlockCopy(bitVaues, 0, buffer, ascii.Length, bitVaues.Length);
buffer[buffer.Length - 1] = (byte)'\n';
return buffer;
```
My initial theory is the BMP format is adding that line as a end of line marker and is not viable when rendered. I am thinking I may have to reparse the file after I have the binary array and take out the 00 00 00 at the end of every line. But I am posting here in case anyone thinks of a better way.

2,598,827 | 1 | 2,598,913 | null | 4 | 9,906 | I'm trying to create a pretty simple WPF interface, and from what I know this should be mostly possible using pure XAML.
I have a pretty basic understanding of WPF so far, however I have a decent grasp on XAML.
I know or can work out how to put content in these panels. This isn't the topic of this question.
I don't know how to animate this interface.
I'm not very proficient at binding, however again, that's not the topic of this question.
The topic of this question is what would be the best way to animate panels 1-4 (images below) so that they may be dragged (via touch) into view. The number of panels here may be static for the purpose of this question.
The panels (1-4) can be stack panels, grids or whatever; their content isnt important. What is important is the container that would contain all 4 panels. The complication in this animation is the other two containers here (Item One/TODO), as they're in the way of a smooth animation.
If it makes this question simpler, the touch features can be ignored for now, and a simple button push can slide the containers across.

But now we have a question: what if our system needs to implement some business logic, only for our application (like some maintenance data for the system itself) that we don't need to share with other systems. Based on this graphic:
As it seems, it will be unnecesary to implement a service layer just for that; it will be more practical to avoid the service layer, and just go from User Interface to the Business Layer (for example). What should be the right way in this case to implement the Service Layer Pattern? What do you suggest us for a scenario like the one I told you?

2,606,554 | 1 | null | null | 1 | 1,149 | Is it possible to use `Maven deploy:deploy-file` or similar to deploy your `main src jar snapshot` and the `test src jar snapshot` to `Archiva` so that it `results in a single entry?`
Currently I have an `Ant` project which has jars I want publishing to Archiva and here is how I am doing it:
```
<!--Main Src Jar-->
<exec executable="${maven.bin}" dir="../lib">
<arg value="deploy:deploy-file" />
<arg value="-DgroupId=com.xxx.gt" />
<arg value="-DartifactId=${ant.project.name}" />
<arg value="-Dversion=${manifest.implementation.version}-SNAPSHOT" />
<arg value="-Dpackaging=jar" />
<arg value="-Dfile=../lib/${ant.project.name}-${manifest.implementation.version}-SNAPSHOT.jar" />
<arg value="-Durl=http://archiva.xxx.com/archiva/repository/snapshots" />
<arg value="-DrepositoryId=snapshots" />
</exec>
<!--Test Src Jar-->
<exec executable="${maven.bin}" dir="../lib">
<arg value="deploy:deploy-file" />
<arg value="-DgroupId=com.xxx.gt" />
<arg value="-DartifactId=${ant.project.name}" />
<arg value="-Dversion=${manifest.implementation.version}-SNAPSHOT" />
<arg value="-Dpackaging=jar" />
<arg value="-Dfile=../lib/${ant.project.name}-${manifest.implementation.version}-SNAPSHOT-tests.jar" />
<arg value="-Durl=http://archiva.xxx.com/archiva/repository/snapshots" />
<arg value="-DrepositoryId=snapshots" />
<arg value="-Dclassifier=tests" />
</exec>
```
The above Ant script will result in `two` snapshots on `Archiva`, 1 with the `main src jar` and the other with the `test src jar`.
Using mvn deploy on a typical Maven project will group the artifacts together.
Has a sanpshot entry per deploy:deploy-file command
Has a single sanpshot entry grouping src and tests jars.
[Here's my earlier post](https://stackoverflow.com/questions/2606106/maven-deploydeploy-file-not-found-due-to-version-timestamp-appended-to-jar) which will help explain how I got to this point.

## Update
I don't think I was clear enough when I originally posted this quesion.
Take a look at these screenshots.
([Link to bigger screenshot here](https://dl.dropbox.com/u/674358/INotifyPropertyChanged1.jpg))
Notice the portions I've boxed in red. The class displayed here implement `INotifyPropertyChanged`, but the VB compiler seems to think that the `PropertyChanged` event as declared does not match the signature of `INotifyPropertyChanged.PropertyChanged`.
([Link to bigger screenshot here](https://dl.dropbox.com/u/674358/INotifyPropertyChanged2.jpg))
Here I've selected the offending line of code. Between this and the next screenshot I literally just the back into the file (i.e., I hit + followed by + ).
([Link to bigger screenshot here](https://dl.dropbox.com/u/674358/INotifyPropertyChanged3.jpg))
Now behold! After cutting and pasting the line back in, the error goes away.
---
## Original question
I have this happen sometimes, particularly with the `INotifyPropertyChanged` interface in my experience but I have no idea if the problem is limited to that single interface (which would seem bizarre) or not.
Let's say I have some code set up like this. There's an interface with a single event. A class implements that interface. It includes the event.
```
Public Interface INotifyPropertyChanged
Event PropertyChanged As PropertyChangedEventHandler
End Interface
Public Class Person
Implements INotifyPropertyChanged
Public Event PropertyChanged _
(ByVal sender As Object, ByVal e As PropertyChangedEventArgs) _
Implements INotifyPropertyChanged.PropertyChanged
' more code below '
End Class
```
Every now and then, when I build my project, the compiler will suddenly start acting like the above code is broken. It will report that the `Person` class does not implement `INotifyPropertyChanged` because it doesn't have a `PropertyChanged` event; or it will say the `PropertyChanged` event can't implement `INotifyPropertyChanged.PropertyChanged` because their signatures don't match.
This is weird enough as it is, but here's the weirdest part: `Event PropertyChanged` The project builds.
Does anybody have any clue what could be going on here?

I've looked at all the [relevant MSDN tutorials](http://msdn.microsoft.com/en-us/library/dd207034.aspx) but they talk about 'data field drop zones' and how a 'Add Calculated Series' menu option should be there but , and no screenshot is provided to show what a 'data field drop zone' is. This is the menu I get when I "right-click on a field in the data field drop zone":
The frustrating thing is I know I've seen this calculated series stuff before, but I can't find it again, it's not in the 'Series Properties' dialog that I can see, and I can't find a tutorial showing how to find this feature.

Can you tell me how I can add a line showing the median of my data to a chart in Report Builder 2.0? I think I can do this by adding a 'Moving Average' via a 'Calculated Series', but I can't find how to add that.
on a different chart, the 'Add Calculated Series' menu option was available. It was a stacked column chart and the series I right-clicked on was an expression that used `RunningValue`.

using a RelativeLayout or something other than AbsoluteLayout which is what this was created with. I'm coming from a Windows programming background where the device adjusts the 'absolute' positioning for you and GUI layout was a non-issue.
The first layout works great in the emulator, but doesn't format for my Nexus One or any other screen that differs from the emulator size. I expected this because it's absolutely positioned, but haven't found a solution that will format correctly for different screen sizes. My goal is to have the layout work for different screen sizes and in portrait / landscape.

2,618,861 | 1 | 2,619,054 | null | 2 | 3,875 | I'm writing an an application in C# that will record audio files (*.wav) and automatically tag and name them. Wave files are RIFF files (like AVI) which can contain meta data chunks in addition to the waveform data chunks. So now I'm trying to figure out how to read and write the RIFF meta data to and from recorded wave files.
I'm using NAudio for recording the files, and asked on [their forums](http://naudio.codeplex.com/Thread/View.aspx?ThreadId=208116) as [well on SO](https://stackoverflow.com/questions/2543335/reading-writing-wav-riff-tags) for way to read and write RIFF tags. While I received a number of good answers, none of the solutions allowed for reading writing RIFF chunks as easily as I would like.
But more importantly I have very little experience dealing with files at a byte level, and think this could be a good opportunity to learn. So now I want to try writing my own class(es) that can read in a RIFF file and allow meta data to be read, and written from the file.
I've used streams in C#, but always with the entire stream at once. So now I'm little lost that I have to consider a file byte by byte. Specifically how would I go about removing or inserting bytes to and from the middle of a file? I've tried reading a file through a FileStream into a byte array (byte[]) as shown in the code below.
```
System.IO.FileStream waveFileStream = System.IO.File.OpenRead(@"C:\sound.wav");
byte[] waveBytes = new byte[waveFileStream.Length];
waveFileStream.Read(waveBytes, 0, waveBytes.Length);
```
And I could see through the Visual Studio debugger that the first four byte are the RIFF header of the file.
But arrays are a pain to deal with when performing actions that change their size like inserting or removing values. So I was thinking I could then to the byte[] into a List like this.
```
List<byte> list = waveBytes.ToList<byte>();
```
Which would make any manipulation of the file byte by byte a whole lot easier, but I'm worried I might be missing something like a class in the System.IO name-space that would make all this even easier. Am I on the right track, or is there a better way to do this? I should also mention that I'm not hugely concerned with performance, and would prefer not to deal with pointers or unsafe code blocks like [this guy](http://www.codeproject.com/KB/files/riffparser.aspx).
If it helps at all here is [a good article](http://www.sonicspot.com/guide/wavefiles.html#wavefileheader) on the RIFF/WAV file format.

[Do I need to disable NSLog before release Application?](https://stackoverflow.com/questions/2025471/do-i-need-to-disable-nslog-before-release-application)
I wonder if someone could help me setup a number of NSLog statements so they print to console when executing in "Debug Mode" but don't print in "Release Mode". I understand I need to add something like `DEBUG = 1` to the debug config in Xcode but I can't find where. Also how do I utilise this in my code?
```
NSLog(@"Print Always");
if(DEBUG) NSLog(@"Print only in debug");
```
Is there a simple way of doing this?
I tried following [this](http://iPhoneIncubator.com/blog/debugging/how-to-create-conditional-log-statements-in-xcode) but the keys now seem to be only listed under "All Settings", and are presenting as nice names. The one I should be using is GCC_PREPROCESSOR_DEFINITIONS, so I needed to find "Preprocessor Macros", select edit and add `DEBUG=1`
When you come to use this its simply a case of adding (see below) or some marco to remove the messy #ifdef / #endif tags.
```
NSLog(@"You always see me?");
#ifdef DEBUG
NSLog(@"Only in DEBUG");
#endif

2,630,492 | 1 | 2,640,535 | null | 10 | 7,122 | I’m in the situation that I have to design and implement a rather big system from the bottom. I’m having some (a lot actually) questions about the architecture that I would like your comments and thoughts on.
I don’t hope that I’ve written too much here, but I wanted to give you all an idea of what the system is.
The applications will be built on Microsoft .NET Framework 4, with a MS SQL Server 2008 database. There will be a few applications that have to access this database, such as:
- - - - -
Now my big problem is what .NET parts I should use for such a system. For the “backend” I’ve considered using Windows Communication Foundation:
Would WCF be a good choice?
The intranet application will be an application that has to edit lots of records in the database. It has to be easy to navigate using the keyboard (fast to work with). Has a feature such as “find customer, find that, lookup this, choose this and update that”. What would be the best choice to develop this application in? Would it be WPF or good old Windows Forms? I don’t need all of the fancy graphics features in WPF, like 3D, but the application has to look nice (maybe something like the new Visual Studio/Office tools).
And the same question goes for the web pages. They have much the same work to do, but not as many features as the intranet application, and not the same amount of data (much less).
That is my questions for now. I’m hoping to get a discussion going that will open my eyes to some of these technologies, helping me decide architecture to go with.
I would like to say thanks in advance, and let you all know that any thoughts will be much appreciated.
---
It seems like many agree that we should use WCF. When introducing an ORM mapper in the data layer, and a service layer using WCF, there must be a performance hit? Do you have any comments on this?
Another question that keeps popping up is how we handle authentication and roles. The intranet application has “master” access (no limitations). However, when a customer retrieves information from the web application about their users, what is returned depends on what their “service level” is and a few other parameters related to the customer. What is the best way to handle this? Are there any patterns/ best practices?

So now the question is: How is it best to separate the data?
This is the only alternative I see:
-
But I feel an extra join (We have around 20 tables that needs extra join) is quite costly.
I hope there are some other best practices or solutions we can consider.
PS: This is a Web application developed using Java/JSF/Seam (but I don't know if that is relevant)
I want to clarify something. My consurn is not security but performance. We have added the foreign key to organization to all relevant tables that has shared data, and we are using user's logged in organization to filter the data.
All I want to know is if this is a good architectural solution (inner join) or if we should do something else (ie: Load all shared data, and filter in memory instead of sql join).

2,638,586 | 1 | 2,638,609 | null | 3 | 578 | My google search skills have failed me, and I am not a database expert by any means! I have a very simple database schema that looks like this:
[database schema http://bit.ly/adeUVL](http://bit.ly/adeUVL)
properties_id in the CANDY table is a foreign key to id in the EXPENSIVE_PROPERTIES table. The properties_id is only set the candy is expensive. If it is expensive, then the corresponding values in the EXPENSIVE_PROPERTIES table will get filled in.
When I want to get a list of the candies, I basically want to do this:
- -
In the past, I have done two queries, but this is silly since I should be able to create a view that aggregates all of the properties into one table, and just leaves the other fields blank if there isn't a corresponding id in the EXPENSIVE_PROPERTIES table.
Can anyone tell me how to create this view in SQLite? I assume it's possible, but couldn't figure it out [from the docs](http://www.sqlite.org/lang_createview.html):
The IF NOT EXISTS elements don't seem to have anything to do with the existence of a particular field value.
The question has been answered, but one thing I find weird is that in some cases I see duplicate entries. I'm using SQLite Administrator, and when I execute the CREATE VIEW statement and look in the results tab, I get unique entries. If I just do a SELECT statement, I get duplicate rows. If I create the view, and then do a SELECT * FROM myview; I also see duplicate rows. Can anyone shed some light on this? Should I create a new question?
Never mind, I found my mistake -- I had two tables after FROM, which causes the duplication.

1. overflow: hidden; doesn't do the trick because I need to set the width wider than the page.
2. float won't work because the text can't escape the width of the inner DIV.
3. I can't set it outside the inner DIV and just position it there as the same problem will still exist.

Basically, a form needs to go through (exactly) 7 people, one by one. Each person can either agree or decline a form.
If one declines, the chain stops and the following people don't even get notified that there a form.
Right now I have thought of those 3 tables: FORM, PERSON, and RESPONSE inbetween. However, my first solution sounds too heavy because each form could have up to 7 responses.
Here we are with the table inbetween. That means that each successful form has 7 rows in the table RESPONSE.
Here we have the responding information directly inside the form. It looks ugly but at least keeps everything as singular as possible. On the bad side I can't track the response dates, but I don't think it is crucial for that matter.
What is your opinion on this? I feel like both of them are wrong and I don't know how to fix that.

2,647,570 | 1 | 2,648,439 | null | 3 | 367 | Our application allows administrators to add “User Properties” in order for them to be able to tailor the system to match their own HR systems. For example, if your company has departments, you can define “Departments” in the Properties table and then add values that correspond to “Departments” such as “Jewelry”, “Electronics” etc… You are then able to assign a department to users.
Here is the schema:
[mindgravy.net](http://www.mindgravy.net/wp-content/uploads/2010/04/image.png)
In this schema, a User can have only one UserPropertyValue per Property, but doesn’t have to have a value for the property.
I am trying to build a query that will be used in SSRS 2005 and also have it use the PropertyValues as the filter for users. My query looks like this:
```
SELECT UserLogin, FirstName, LastName
FROM Users U
LEFT OUTER JOIN UserPropertyValues UPV
ON U.ID = UPV.UserID
WHERE UPV.PropertyValueID IN (1, 5)
```
When I run this, if the user has ANY of the property values, they are returned. What I would like to have is where this query will return users that have values BY PROPERTY.
So if PropertyValueID = 1 is of Department (Jewelry), and PropertyValueID = 5 is of EmploymentType (Full Time), I want to return all users that are in Department Jewelry that are EmployeeType of Full Time, can this be done?
---
Here's a full data example:
- - -
My query should only return User A using the above query
### UPDATE:
I should state that this query is used as a dataset in SSRS, so the parameter passed to the query will be @PropertyIDs and it is defined as a multi-value parameter in SSRS.
`WHERE UPV.PropertyValueID IN (@PropertyIDs)`

2,648,079 | 1 | null | null | 1 | 440 | I'm currently struggling with implementing text floating in TLF. It does not support it natively, and the only solution I've found so far is to use linked containers and then combine controllers using flowComposer for single textFlow.
However, I need to implement Dropped Initial letter feature in my column layout. Initial is just a first big letter in paragraph, floated by the rest of the text. It looks like this -
The issue here is that for that big letter, the resulting TLF textFlow sprite is bigger than the actual letter. It's because of the baselines (small q vs big A for example). But I don't want these extra gaps. After textFlow is rendered, I would like to learn how big the resulting letter exactly is (in pixels) so that I can crop/shift baseline, etc.
ContainerController.getContentBounds().height or
ContainerController.compositionHeight
gives me height of whole sprite with gaps added, not the letter.
Is there some kind of measure method for this?
Can this be solved differently?

2,648,838 | 1 | 2,648,919 | null | 2 | 5,913 | We are building a new SharePoint 2007 web site to replace our intranet website for the company I work for, and a common debate keeps coming up. Specifically, should we be using multiple document libraries (ex. 1 for each department), or one document library with multiple folders within (ex. 1 library with 1 folder for each department).
I know the benefits of using one document library and using custom views to organize the documents by utilizing custom columns (like department, purpose, location, etc).
Also, authorization can be set at either the document library or the folder level, so that does not seem to benefit either choice.
It would also seem that a single document could appear in multiple views in the same document library, but the document would have to be copied to other document libraries if that strategy is used.
The current plan is to use one document library for all organization documents, and then put a bunch of folders within, that symbolize the organization's structure. This would make it easy for a user to upload a document to their own organizational folder (with privileges assigned to that folder before hand). Then, when adding the document, they would choose custom column fields to identify the document and "tag" it, that will enable the custom views to filter the document into multiple views (like departmental, purpose, etc).
I don't think views are applicable for linking multiple document libraries to show their contents.
Anyway, the main question is:
Is there any benefit of using multiple document libraries vs. 1 document library with multiple folders?

2,649,544 | 1 | 2,649,560 | null | 59 | 24,057 | I want to build a Python function that calculates,
and would like to name my summation function Σ. In a similar fashion, would like to use Π for product, and so on. I was wondering if there was a way to name a python function in this fashion?
```
def Σ (..):
..
..
```
That is, does Python support unicode identifiers, and if so, could someone provide an example for it?
Thanks!
---
Original motivation for this was a piece of Clojure code I saw today that looks like,
```
(defn entropy [X]
(* -1 (Σ [i X] (* (p i) (log (p i))))))
```
where Σ is a macro defined as,
```
(defmacro Σ
... )
```
and I thought that was pretty cool.
---
BTW, to address a couple of comments about readability - with a lot of stats/ML code for instance, being able to compose operations with symbols would be really helpful. (Especially for really complex integrals et al)
```
φ(z) = ∫(N(x|0,1,1), -∞, z)
```
vs
```
Phi(z) = integral(N(x|0,1,1), -inf, z)
```
or even just the lambda character for lambda()!

OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes.
I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing >50k pixels wide and also let's the svg converter fail(only renders about the half of the graph).
I went through the [docs](http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick.
So the question is:
Is there a simple way to do this or do I have to layout the whole thing by myself? :/
Thanks to Andrews comment I've got the right layout, the only problem now is that it's a bit to "compact"... so the question now is, how to fix this?

S = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 }
Now, what I want to do is shuffle them to create a new instance of the puzzle. However, I know that if I create a board with an "odd permutation" than it is unsolvable.
Wikipedia says I need to create the puzzle with an even permutation. I believe this means that I simply have to do ensure I do an even number of swaps?
How would I modify Fisher-Yates so I ensure I end up with an even permutation at the end? If I do a swap for every element in the array that would be 16 swaps which I believe would be an even permutation. However, do I need to be concerned about swapping with itself? Is there any other way to ensure I have a valid puzzle?

2,653,812 | 1 | null | null | 10 | 3,178 | I am using Dundas Maps and attempting to draw a map of the world where countries are grouped into regions that are specific to a business implementation.
I have shape data (points and segments) for each country in the world. I can combine countries into regions by adding all points and segments for countries within a region to a new region shape.
```
foreach(var region in GetAllRegions()){
var regionShape = new Shape { Name = region.Name };
foreach(var country in GetCountriesInRegion(region.Id)){
var countryShape = GetCountryShape(country.Id);
regionShape.AddSegments(countryShape.ShapeData.Points, countryShape.ShapeData.Segments);
}
map.Shapes.Add(regionShape);
}
```
The problem is that the country border lines still show up within a region and I want to remove them so that only regional borders show up.
Dundas polygons must start and end at the same point. This is the case for all the country shapes. Now I need an algorithm that can:
- - -
Below is where I have gotten to so far with the map. You can see that the country borders still need to be removed. For example, the border between Mongolia and China should be discarded whereas the border between Mongolia and Russia should be retained.
The reason I need to retain a regional border is that the region colors will be significant in conveying information but adjacent regions may be the same color. The regions can change to include or exclude countries and this is why the regional shaping must be dynamic.
I now know that I what I am looking for is a UNION of polygons. David Lean [explains how to do it](http://blogs.msdn.com/davidlean/archive/2008/10/25/sql-2008-spatial-samples-part-n-2-on-n-geometric-set-theory-methods.aspx) using the spatial functions in SQL Server 2008 which might be an option but my efforts have come to a halt because the resulting polygon union is so complex that SQL truncates it at 43,680 characters. I'm now trying to either find a workaround for that or find a way of doing the union in code.

2,655,155 | 1 | 2,655,270 | null | 1 | 650 | I have a function that takes longitude and latitude and converts it to x and y to be plotted. The conversion to X and Y is working fine and that is not what I have the problem with.
I want to ensure that two points are not plotted in the same place. In one set of results there are about 30 on top of each other (because they have the same latitude and longitude), this number could be a lot larger.
At the moment I am trying to achieve this by moving points to the left, right, top or bottom of the point to make a square. Once a square made up of points has been drawn, then moving to the next row on and drawing another square of points around the previous square.
The code is Javascript but it is very generic so I guess it's slightly irrelevant.
My code is as follows:
```
var prevLong, prevLat, rand = 1, line = 1, spread = 8, i = 0;
function plot_points(long, lat){
// CODE HERE TO CONVERT long and lat into x and y
// System to not overlap the points
if((prevLat == lat) && (prevLong == long)) {
if(rand==1) {
x += spread*line;
} else if(rand==2) {
x -= spread*line;
} else if(rand==3) {
y += spread*line;
} else if(rand==4) {
y -= spread*line;
} else if(rand==5) {

} else if(rand==7) {

} else if(rand==8) {
x -= spread*line;
y += spread*line;
// x = double
} else if(rand==9) {
x += spread*line;

} else if(rand==10) {
x += spread;

} else if(rand==11) {

} else if(rand==18) {

} else {
line = 1;
i = 0;
}

return [x,y];
}
```
This is the output: 
It isn't working correctly and I don't even know if I am approaching the problem in a correct way at all.
Has anyone had to do this before? What method would you suggest?

The scene looks OK with two different light sources, but when both lights are in the scene, there are dark shadows where the lit area from one ends, even if in the middle of a lit area from the other light source (particularly noticeable on the green ball). The transition from the 'area lit by both light sources' to the 'area lit by just one light source' seems to be slightly darker than the 'area lit by just one light source'.

Because there is only one element in the page with a given ID, there’s

Instead of qualifying class selectors for specific tags, extend

2,658,717 | 1 | 2,658,947 | null | 7 | 1,180 | Greetings,
I'm working on a game project that uses a 3D variant of hexagonal tile maps. Tiles are actually cubes, not hexes, but are laid out just like hexes (because a square can be turned to a cube to extrapolate from 2D to 3D, but there is no 3D version of a hex). Rather than a verbose description, here goes an example of a 4x4x4 map:
I have a struct type to represent tiles, and maps are represented as a 3D array of tiles (wrapped in a `Map` class to add some utility methods, but that's not very relevant).
Each tile is supposed to represent a cubic space, and they are all the same size. Also, the offset between adjacent "rows" is half the size of a tile.
That's enough context; my question is:
`A``B``A``B`
That would later be used for a variety of purposes, such as determining Line-of-sight, charge path legality, and so on.
BTW, this may be useful: my maps use the (0,0,0) as a reference position. The 'jagging' of the map can be defined as offsetting each tile `((y+z) mod 2) * tileSize/2.0` to the right from the position it'd have on a "sane" cartesian system. For the non-jagged rows, that yields 0; for rows where `(y+z) mod 2` is 1, it yields 0.5 tiles.
I'm working on C#4 targeting the .Net Framework 4.0; but I don't really need specific code, just the algorithm to solve the weird geometric/mathematical problem. I have been trying for several days to solve this at no avail; and trying to draw the whole thing on paper to "visualize" it didn't help either :( .
Thanks in advance for any answer

I've been having a problem where for some reason my message that I pass from one process to another only displays the first letter, in this case "M".
My application based on a [MSDN sample](http://msdn.microsoft.com/en-us/library/aa366551(v=VS.85).aspx) so to make sure I hadn't missed something I create a separate solution, added the MSDN sample (without any changes for my needs) and unsurprisingly it works fine.
Now for the weird bit, when I run the MSDN sample running (as in debugging) and have my own application running, the text prints out fine without any problems. The second I run my on its own without the original MSDN sample being open it fails to work and only shows an "M".
I've looked in the debugger and don't seem to notice anything suspicious (it's a slightly dated picture, I've fixed the data type inconsistency).
Can anyone provide a solution as to this? I've never encountered anything like this before.
To look at my source code it's easier to just look at the link I posted at the top of the question, there's no point in me posting it twice.
Thank you for any help.
After further investigation it almost seems that my own application is somehow reading the other applications memory by accident. If I "poll" for the message without even sending it via the producer window, it still gets the message which must mean it's reading it from the other (MSDN) process, this would also explain why it only works properly when I run the MSDN sample first.
I still don't understand why this happens, how to stop it and how to fix it, this is possibly the strangest thing I've come across.
****Solution:****
Although it does not fix the problem of both applications affecting each other I have managed to fix the text problem. I did not add the necessary #include to both files, adding this fixed it without any warnings.
It's always the little things.

The font used by the ribbon does not match the font the user has chosen as their Windows preferences - which is the preference my application uses. This means that as the font in Windows gets bigger, the ribbon gets smaller.
Notice how the ribbon gets smaller in each screenshot:
## Segoe UI 9pt (Windows default)
## Segoe UI 12pt (what i use)
## Segoe UI 16pt (what customer's use)
You can see by the time we get to 16pt, the text on the ribbon is quite hard to read.
## Background
The user can configure Windows to use their preferred , e.g.:
- - -
and their preferred , e.g.:
- - - - -
but the by default uses a font that is the user's preference.

The ribbon does allow customizing the of the ribbon.
The following code fragment is used to set the `UI_PKEY_GlobalBackgroundColor` of the ribbon. In this case i use a color that is the user's currently select Aero color scheme:
```
IUIFramework framework;
...
TColor glass = Dwm.GetColorizationColor();
VarCast(v, ColorToUIHSB(glass), UI_PKEY_GlobalBackgroundColor.pid);
IPropertyStore ps = framework as IPropertyStore;
ps.SetValue(UI_PKEY_GlobalBackgroundColor, PROPVARIANT(v));
ps.Commit;
```
And now the ribbon is now colored to match the color scheme of Windows:
[](https://i.stack.imgur.com/H2EoH.png)
But i can't find the option to change the font face/size.
While the ribbon honor the user's DPI settings, that isn't question.

## It works in Outlook 2010
It might be helpful to note that Outlook 2010's ribbon does honor the user's (menu) font preferences. You can get the user's menu font by calling `[SystemParametersInfo][6]`:
```
SystemParametersInfo(SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS), &ncm, 0));

```
## 9pt Outlook 2010
## 12pt Outlook 2010
## 12pt Outlook 2010
Notice the ribbon increases in size with the font size? (Which, in these resized screenshots, means that the ribbon does not get perceptually smaller.)
There are two possibilities:

## Windows 7 Paint doesn't work
It's also useful to note that Windows Paint in Windows 7 does honor the user's font preferences. This leads me to believe that it (mspaint) does use the Windows Ribbon Framework, and that the Windows Ribbon Framework doesn't support setting a font size. If if you've actually tried to be helpful, and read all the way down to here, you'll realize this is the correct answer: it's not possible. So if you want a free 300 rep, you add that as an answer.

P(i,j) = \sum_{x=|N(V_i) \cap V_j|}^{\min\{|V_j|, |N(V_i)|}

```
class Node {
Node next;

and each Node points to the next node, except for the last Node, which has null for next. Say there is a possibility that the list can contain a loop - i.e. the final Node, instead of having a null, has a reference to one of the nodes in the list which came before it.
What's the best way of writing
```
boolean hasLoop(Node first)

which would return `true` if the given Node is the first of a list with a loop, and `false` otherwise? How could you write so that it takes a constant amount of space and a reasonable amount of time?

I had thought that one must use the resize event of the form and them force each element in the form to resize.
But then I saw some sample code which, even when I am editing the form, the elements seem to adhere to a percentage of the space they take up in the form rather than a set diminsion. In other words, when I am editing the form and resizing it, the panels and the parts inside the form bend their shape such that the edges remain a few pixels from the edges.

2,669,080 | 1 | 2,669,183 | null | 3 | 3,591 | Greetings, Overflowers!
I am writing an application in PHP that will allow for editing various blocks of content via a button that loads a CKEditor Instance inside a jQuery-UI Modal Dialog box.
I've got the button working to launch the Dialog, as shown in these screenshots:
The example shows the 'Main Content' content inside the Dialog ready to edit. The way I'm doing this presently is a hack simply for demo purposes - I have duplicate content hard-coded into the hidden #dialog div.
What I'd like to be able to do is have it so that when the 'Edit Main Content' button is pushed, all content (HTML, Styling, Etc) gets passed by jQuery into the CKEditor instance for edit, and when a 'Save/Submit' button is pressed inside the dialog, the changes are saved via Ajax as well as passed back into the page being edited.
I'm not too concerned about the Ajax bit at this point, as I'll be needing to use the WordPress Ajax API, which is outside the scope of this question.
The main thing, though, is to pass data from the 'Main_Content' div -into- the #dialog when the 'Edit Main Content' button is clicked, and then pass the edited data from the #dialog window back into the 'Main_Content' div after a 'Save Changes' button is pressed.
Any help will be greatly appreciated! I'm totally stuck.
Thanks!

Even some high profile application icons such as Google Chrome look terrible while Firefox, Skype and MS Office icons look sharp:
(example)
I suspect that most icons look blurry because a lower resolution icon is scaled up rather than using a higher resolution icon.
I want to give my application a high quality icon and can't seem to convince Windows to use the higher resolution icon. I have created a multi-resolution icon with the icon editor [IcoFX](http://icofx.ro/). The icon is provided in (all in 32 bit including alpha channel) yet Windows seems to use the 48x48 version of the icon on the desktop and scale it up which looks terrible. (I am using Windows 7 - 64 bit - the icon is placed by means of setting up a shortcut in the msi (created via Visual Studio 2008 Setup Project) and pointing it to the .ico file that contains the multi-resolution icon)
I have tried removing the 128x128 icon but to no avail. Interestingly in Windows Explorer the icon looks great even when using the Extra Large Icon setting.
EDIT: I tested removing the 128x128 option, then both the 48x48 and 128x128 option and tried Axialis IconWorkshop to create the icon - nothing worked.
EDIT: After much trial and error I think When setting the icon for the link in the editor it only gives me one option (index 0) which seems to be the 48x48 icon. I have tried manually adjusting the IconIndex in the .vdproj but had no luck.

When I use `System.Windows.Forms.TextRenderer.MeasureText(...)` to measure the text, I get dimensions that include font padding. When the text is rendered, it seems to use the same padding.
Is there any way to determine the size of a string of text and then render it without any padding?
This is the code I've tried:
```
// Measure the text dimensions
var text = "Hello World";
var fontFamily = new Font("Arial", 30, FontStyle.Regular);
var textColor = new SolidBrush(Color.Black);
Size textSize = TextRenderer.MeasureText(text, fontFamily,
Size.Empty, TextFormatFlags.NoPadding);
// Render the text with the given dimensions
Bitmap bmp = new Bitmap(textSize.Width, textSize.Height);
Graphics g = Graphics.FromImage(bmp);
g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;
g.DrawString(text, fontFamily, textColor, new PointF(0, 0));
bmp.Save("output.png", ImageFormat.Png);
```
This is what currently gets rendered out:

This is what I want to render:

I also looked into `Graphics.MeasureString(...)`, but that can only be used on an existing `Graphics` object. I want to know the size before creating the image. Also, calling `Graphics.MeasureString(...)` returns the same dimensions, so it doesn't help me any.

2,679,698 | 1 | null | null | 10 | 10,756 | So I'm have a hard time figuring out when I should be attaching to an object and when I shouldn't be attaching to an object. First thing's first, here is a small diagram of my (very simplified) object model.
In my DAL I create a new DataContext every time I do a data-related operation. Say, for instance, I want to save a new user. In my business layer I create a new user.
```
var user = new User();
user.FirstName = "Bob";
user.LastName = "Smith";
user.Username = "bob.smith";
user.Password = StringUtilities.EncodePassword("MyPassword123");
user.Organization = someOrganization; // Assume that someOrganization was loaded and it's data context has been garbage collected.
```
Now I want to go this user.
```
var userRepository = new RepositoryFactory.GetRepository<UserRepository>();
userRepository.Save(user);
```
Neato! Here is my save logic:
```
public void Save(User user)
{
if (!DataContext.Users.Contains(user))
{
user.Id = Guid.NewGuid();
user.CreatedDate = DateTime.Now;
user.Disabled = false;
//DataContext.Organizations.Attach(user.Organization);
DataContext.Users.InsertOnSubmit(user);
}
else
{
DataContext.Users.Attach(user);
}
DataContext.SubmitChanges();
// Finished here as well.
user.Detach();
}
```
So, here we are. You'll notice that I comment out the bit where the DataContext attachs to the organization. If I attach to the organization I get the following exception:
>
Hmm, that doesn't work. Let me try it attaching (i.e. comment out that line about attaching to the organization).
>
WHAAAAT? I can only assume this is trying to insert a new organization which is obviously false.
So, what's the deal guys? What should I do? What is the proper approach? It seems like L2S makes this quite a bit harder than it should be...
I just noticed that if I try to look at the pending change set (dataContext.GetChangeSet()) I get the same NotSupportedException I described earlier!! What the hell, L2S?!

2,682,144 | 1 | 12,956,923 | null | 38 | 17,178 | R has a useful function `pairs` that provides nice matrix of plots of pairwise connections between variables in a data set. The resulting plot looks similar to the following figure, copied from [this blog post](http://statisticsr.blogspot.com/2009/12/r-pairs-plot.html):
Is there any ready to use function based on python's matplolib? I have searched its [gallery](http://matplotlib.sourceforge.net/gallery.html), but couldn't find anything that resembles what I need. Technically, this should be a simple task, but proper handling of all the possible cases, labels, titles, etc is very tedious.
see below my answer with a quick and dirty approximation.

2,682,546 | 1 | 2,682,580 | null | 0 | 137 | I am just putting the finishing touches to an iPhone app that I have written, signed up to the developer program and installed Xcode 3.2.2 (1650) My question is which version of the SDK should I be using to build my application? I was thinking I should be using the latest 3.2 but when I select that I can only access the iPad simulator ...
Should I be using 3.1.3 which runs the iPhone simulator. (NB: I originally developed the app in 3.1.2
