• Visual Studio Express Editions Problem installing VB.NET 2005 express.

  Whenever I try to install VB.NET 2005 Express Edition on my machine, setup displays following error: Error 1304: Error writing to file: Microsoft.VSDsesigner.dll.

• Visual Studio Express Editions Table only updates once during runtime...

  I have a dataset that i am updating during runtime of my program.  To do this, I first delete all of the data in a datatable using "DELETE * FROM Table1" command, and then updating the dataset.  To initiate the update, i double click on a datagrid.  The first time i double-click on the data grid, the program works exactly as planned--i step through the code and verify that first all the records in the datatable delete, and then is updated with all the new records.  The problem i'm having is that the next time i double-click on the datagrid, the table doesn't delete!   Why would this happen   Here's my code: Sub UpdateTeamTable() Dim dt As New DataTable Dim strSQL As String Dim int1 ...Show All

• .NET Development Reducing memory usage with XslCompiledTransform

  I've currently been using and XslCompiledTransform in my software to apply an XSL stylesheet to a user-provided XML file and then bulkloading the resulting file into a SQL table. This worked great until an XML file larger than 100 MB is thrown into the mix. The RAM usage jumps off the charts and for most users, my program exits will an OutOfMemory Exception. I've looked for ways to get around this and cannot seem to find any solutions. What can I do differently or what other alternatives do I have other than physically parsing through the XML file line by line (or node by node) and performing the operations the XSL file does myself... which is my LAST option considering I am sometimes dealing with 2GB and 3GB XML files. Oh.. and here's ...Show All

• Visual Basic Create a class that disables specific controls

  Hi guys, I am considering creating a class that disables certain controls on my form when it loads. Opposed to setting each 'enabled' property to false, i think a class that executes when the form does, is the most efficient. Am i right, is this efficient If so, how exactly would i go about coding it Many thanks in anticipation for your help. Kyle Well it depends upon what your overall objective is...If it is to just disable controls on load of a form then you can do that in the designer or you can do it in the load event of the form. kitsch wrote: Opposed to setting each 'enabled' property to false What method would your class use to disable the controls ...Show All

• Visual Studio How to integrate custom DSL with Class Designer?

  Hello, at PDC 05, Jochen Seemann demonstrated that a custom DSL can be integrated with the Class Designer that is part of Visual Studio 2005. I'm doing a quick research on this topic but found no good resources. Can somebody please point me to the appropriate documentation or samples I would be very graceful. Thank you, Borek Hi, my concrete situation is that I want to build a DSL that is more abstract than Class Diagram. In my top-level DSL, I want to be able to click on some diagram element, select "Drill down into Class Diagram" and to show appropriate objects in CD. But your response was informative, thank you.

• Game Technologies: DirectX, XNA, XACT, etc. Reset or not reset a IDirect3DDevice9?

  Hi @ all, i'd want know if calling IDirect3DDevice9::reset() is the correct way after switching from windowed mode to fullscreen. In PresentParameters there are some attributes that have sense only in fullscreen mode, as well as FullScreen_RefreshRateInHz or MultiSampleType. Have I to call reset() function Is it the correct way What do I have still to check Thx ;) Yes Reset() is the right way to switch to full screen, it's also the way to change any present parameter. Take care that windows style often need to be modified when moving to fullscreen : see Dx tutorial Step 1-"Creating a Window" for more details about that. You could also have a look to DXUT code which does that well. ...Show All

• Visual C# Versatility/Practicality of C#?

  Hey all, new to posting but ive been reading here for a few weeks. Anyway, on with my question (which probably has been asked in some way already)- How versatile is VC# compared to VC++ All I generally see are simple (*duck/cover* ) desktop applications. I've read that its possible to do game dev (including DX and OpenGL), but I have yet to find any engines done in C#. I have just looked at API's/engines/SDK's for games, but I have not gotten actually into manipulating/programming in them yet. I've done some basic reading on C# and I sort of want to get into it, but I plan on in a few years down the line working for Lockheed (or a defense contractor of some sort) or EA-Tiburon. I've been programming since I was probably around 10, ...Show All
