• Game Technologies: DirectX, XNA, XACT, etc. Using AudioVideoPlayback in c#

  Hello I try to display the FileCopy.avi file that comes with VisualStudio (in the graphics library). I did some searching and found that the (only) way to display avi files in c# is to use the Video class in the AudioVideoPlayback namespace that comes in the DirectX 9.0 sdk. ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/directx9_m/directx/audiovideoplayback/audiovideoplayback.asp ) The problem is that FileCopy.avi file (and all the rest of the AVIs that comes with VS) has a background color that needs to be transparent (a purple color in the FileCopy.avi). In VisualBasic 6 there is an AnimationControl that display AVI files and its have the BackStyle property for the transparent option (if transparent i ...Show All

• Smart Device Development How to register COM object on Windows Mobile device?

  Ok so I know on the desktop you can create a COM component and register it so it's in the registry and sorta globally visible to all applications - but how would one do it on Windows Mobile I got Platform Builder and Visual Studio 2005 if anyone wants to know what I'm working with here. I need to access the COM component remotely, so I'd need to do this for that to work. If you have platform builder, there is a tool called regsvrce. See item 13. here http://msdn.microsoft.com/library/default.asp url=/library/en-us/dncenet/html/buildxml.asp That assumes that your com DLL implements DllRegisterServer(). Any ATL project will have this done for you. If you have a vanilla Win32 project check out the Dvo ...Show All

• Windows Forms Hyperlink as a treenode?

  Is it possible to have a tree sub-node as a hyperlink, or at least to make the treenode behave like one (change the cursor to a hand etc). Try using the MouseMove event. You can find out what node it is pointing at with the GetNodeAt() method, change the cursor accordingly. A simple example that uses the Hand cursor at nested nodes: Private Sub TreeView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseMove Dim node As TreeNode = TreeView1.GetNodeAt(e.Location) If node IsNot Nothing AndAlso node.Level > 0 Then TreeView1.Cursor = Cursors.Hand Else TreeView1.Cursor = Cursors.Default End If End Sub ...Show All

• .NET Development data reader already open error occuring

  Hi , I'm writing an application in which i'm using a datareader to reader the data of the table after reading each row i have to update that records into another table.I'm using the same connection for both datereader and the execute nonquery. Is there any other way to do this without using a second connection to open.Please respond ,any little help is appreciated. -regards GRK The best thing to do is to perform all of the updates in a single sql statement or stored procedure. i.e. UPDATE tablename SET field = 0 WHERE field2 = 1 If the logic requires many complicated checks you can set up a cursor in a stored procedure, loop through each record and perform the updates in the stored procedure. This reduces the number of ...Show All

• SharePoint Products and Technologies Users NOT listed in portal site are able to login (after upgrade)

  Hi there, Some time ago I upgraded our SPS portal site to MOSS 2007.

• SQL Server Logging dynamic SQL variable when EvaluateAsExpression=TRUE

  I am trying to use the idea as mentioned by Jamie at: http://blogs.conchango.com/jamiethomson/archive/2005/12/09/2480.aspx which is to build dynamic SQL using a variable evaluated as an expression. Set Expression= "SELECT * FROM MyTable WHERE MyColumn = " + @[VariableContainingFilterValue] Everything works fine. The entire package works. My next step is to log the variable so that I know, after package execution, exactly what SQL statement the package is executing. I tried to do it by a couple of ways in a Script task: 1) Dts.Events.FireInformation(0, String .Empty, String .Format( "SQL: {0}" , Dts.Variables( "SourceSQL" ).Expression), String .Empty, 0, False ) ...Show All

• Visual Studio "Entering break mode failed for the following reason: Source File XXX does not belong to the project being debugged

  I get this modal message box if I copy a solution with multiple projects from one folder to another and try to run it. This never happened with the previous version. I have tried everything I can think of: rebuilding, deleting all the dlls/pdbs to force them to be recreated, editing the csproj & sln files with notepad looking for references to the old folder structure... Somewhere vs.net is picking up the old folder path because it appears in the message box but I can't discern where this information is stored.
