• Visual Studio 2008 (Pre-release) Example accessing controls

  Does anyone have any pointers on accessing form controls with LINQ In the video with Anders he talks about doing just that but what is the best way of doing it Lets say I can logically group my controls (with controls in multiple groups). How would you differentiate them - with tags Could someone post a sample that accesses controls Thanks! I'm not sure if this is what you are refering to, but I threw together a quick sample that might help. The below example queries the form's controls collection and only returns the textboxes leveraging the .OfType query operator. On additional consideration to note, you need to use the Cast extension method to convert the ControlCollection (me.controls) in ...Show All

• Visual Studio 2008 (Pre-release) 3D Scatter Graph in WPF - Ideas?

  Hey folks, We're building a 3D scatter graph control and are having performance issues when adding lots of points (3000+). I don't suspect it is a WPF problem per say but rather, we are not very efficient in the manner which we are doing the graph. In short, our app adds 3D cubes into the viewport at specific coordinates. // 1. Make the 3D object (mesh and material) GeometryModel3D cube = new GeometryModel3D (( MeshGeometry3D )Resources[ "ZPlane" ], ( Material )Resources[ "SteelBlue" ]); // 2. Define how the 3D object will be positioned in space ModelVisual3D model = new ModelVisual3D (); model.Content = cube; Transform3DGroup myTg = new Transform3DGroup (); myTg.Children.Add(( Tran ...Show All

• .NET Development MSXML2 vs .NET

  I've been having a little bit of succes employing my past knowledge of MSXML2 to create and send requests to an Axis based webservices. But clearly there must be a .NET way to achieve the same result. Currently I read request from a file sub the proper fields and parse the result with MSXML2.DOMDocument. This seems like a pain considering that in some point in time I need to select nodes and find values in these responses. What I have in MSXML2 (and works) is found below. How do I get this done in the .NET FW static public string sendRequest( string message ) { output.WriteLine( string.Format( @"{0:yyyy\/MM\/dd HH\:mm\:ss.ff (zz)} > {1}", DateTime.Now, message ) ); // // create request // MSXML2.XMLHTTPClass http; ...Show All

• SQL Server Report Builder and NULL values

  Hi, I am trying to create a report with Report Builder, using a simple data model residing on SQL2005 reporting server. The problem that literally drives me crazy is that I can't find any way to handle NULL values in my report. Say, a table has 3 numeric columns, and I need to create a formula to make a sum of those 3 columns. This would be an ordinary sum for the same entity, not an aggregate. So I create a new formula with following body: Field1 + Field2 + Field3 The problem is, each one of the 3 columns can have NULL values, and if any column actually is NULL, I end up with empty sum value, instead of having sum of those columns that do have values. What I need is one of the following: - a way to check for NULL values ...Show All

  Hello, I've just installed the Windows Vista Beta 2 (Build 5384) and so far so good, except for one thing: somehow i can't activate the option to show the power icon on the "notification are" of the "taskbar".

• Visual Studio Stop VS from showing last used files when opening a solution.

  Hello everyone! When I start Visual Studio by double-clicking on a solution file it always opens up the files that I had open when I last closed the solution. How can I stop Visual Studio from doing this I don't want any files to be opened so I can select which one I want in the solution explorer. Thanks in advance! Thats not what I was looking for.

• Visual C++ Best approach for IPC...? Confusion about what to use...

  Dear all I have been thinking the last few days of a best way to achieve this task: I have two pieces of software. They are both independent application and are final products.(i cant modify the soure).But they both provide an API listing methods that i might want to use to extend some functionality. What i would like to do is as follows: If i am in PROGRAM A and i click the mouse i would like to transfer the mouse click to PROGRAM B.Or if i drag the mouse in PROGRAM A i would like to do the same event in PROGRAM B and vice versa. The API specifies how to do the clicks and drags in both applications but the problem is how to initiate those functions...... I was doing some work and i can identify the window handles and thought that i can s ...Show All

• Software Development for Windows Vista XP Compatibility

  I recently started going to school for Game Design and we are learning C++ and using Visual Studio to do our program. Right now, we're only doing simple "Hello World" programs or some with a little bit of user input, but nothing fancy. They just run in the console. Well I'm the only one in the class that has Vista, we're suppose to use XP, but Vista's sweet. I was wondering if my simple apps will have any compatibility issues with running on XP. They're simple and dont use any of Vista's sweet features or anything, so they should be backwards compatible, right Thanks it depends what .NET Framework you are using to develop in. Currently it's .NET 2.0 but Vista will ship with .NET 3.0. If you ar ...Show All
