• Visual C++ Handling exceptions thrown from a DLL compiled with /clr within a pure C++ host application

  Greetings! I have an application that needed to be compiled in pure C++ to support some statically linked libraries that my company has written, but I wanted to take advantage of the ease of C# programming with VS2005 and .Net 2.0. My application has three components then: a managed assembly with the bulk of the application code, a DLL used for marshalling the few calls that the application will make, and the host executable itself. The problem I'm having is with regards to how to throw exceptions from code within the managed DLL to be caught by pure unmanaged code in my application. Every time I try to do this, I get the following message: "An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in (my m ...Show All

• Visual Studio Team System Working folder is already in use

  Just migrated from VSS to TFS and its fantastic! Having a problem on my PC when trying to get source code for a project. I get the message ' The working folder is already in use by another workspace on this computer'. I have cleared all the work spaces for all users on my machine (as far as I can tell) by clearing down the C:\Documents and Settings\[user]\Local Settings\Application Data\Microsoft\Team Foundation\1.0\Cache\VersionControl.config files. I have also had a poke around in the tbl_Workspace and tbl_Workingfolder on the server to make sure there are no stray workspaces defined. Does anyone have any ideas on how to resolve this One thing that may be causing the problem is that our development team is working on vir ...Show All

• Visual Basic Recent Projects List on Start Page is not being Populated

  The Projects List on my Start Page is not being populated with the Projects I open. It's empty. Does anyone know what could be the problem I can see the entries being recorded in the Registry key: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList But VS isn't reading them in for some reason. I'm running Visual Studio 2005 Professional. Thanks. Right, I had to modify the group policy for my users: User Configuration/Administrative Templates/Start Manu and Taskbar Do not keep history of recently opened documents -> disable or no config. This policy had been set long ago and I pretty much forgot about it. So, here is a follow-up question: Where can I find a document ...Show All

• Visual Studio Express Editions Database Connectivity: Too Much VBA Experience I think

  ok... I'm pulling my hair out at this point. I have been developing EVERYTHING in VBA for MS Access since 95. SO, I am new to VB.NET AND to VB Express. I went through the Add Data Source Wizard and added my Access Database out on my network. I am trying to write some necessary classes for working with and manipulating the data that I want to pull and manipulate. In my old VBA Applications, I would write Class Modules. One for each table. Each Class would have a LOAD Public Function that well... let me show you...

• Game Technologies: DirectX, XNA, XACT, etc. Fullscreen problems.... (SOLVED)

  EDIT: I am using Beta 2. I use this as the constructor method... public Game1() { graphics = new GraphicsDeviceManager(this); graphics.PreferredBackBufferWidth = 640; graphics.PreferredBackBufferHeight = 480; graphics.PreferMultiSampling = true; graphics.ToggleFullScreen(); content = new ContentManager(Services); } Works great. But when I change the resolution to 800x600, all I get is a black screen. The loop is still running because I can still quit the program. I have also tried 1024x768, that works too. Thought maybe it was an aspect ratio problem, but they are all the same, 1.3333... I have tried turning the multisampling off to no avail. Didnt think that would be it anyways, I play World of Warcraft at 800x60 ...Show All

• Windows Forms DataGridView: New row not added when edited programmatically

  I have a DataGridView that displays a DataTable to the user. If the user presses the F3 key while in a cell, I show a popup window that allows the user to enter detailed information for the cell. When the ok button on the popup is pressed, the total of the details is put into the cell. This works fine, except when this is done in a cell on the new row. As soon as the user types a character in one of these cells on the new row, the DataGridView automatically adds the row to the DataTable and another empty new row is displayed in the DataGridView. But, if the user presses F3 and I programmatically set the cell's value in the DataGridView_KeyDown event, the row is not commited to the DataTable and another empty new row is not displayed in ...Show All

• Visual C++ position of combobox in an toolbar.

• Windows Forms DataGrid Master/Detail... close but not right

  I am using a DataGrid, not the Datagridview, to create a Master/Detail Grid. When I run it, it displays the Master data with a expand button on each row, which is great. When I click to expand it simply gives me a clickable hyper-link to another table containing the child row. Any way of just having that child row display in place of the hyperlink I realize I can go out and get a custom 3rd party DataGrid, but I would like and use the regular good old fashioned one if possible... thanks. Sorry you can not show more than one table at a time in the datagrid.

• Game Technologies: DirectX, XNA, XACT, etc. surfaceformat question

  Hi guys, I have what is hopefully a simple problem. Maybe I am just missing something obvious, but I can't seet to initialize a rendertarget2D on the xbox360 with the SurfaceFormat.Rgba64 format. Every time I specify this format, I get a "Cannot Create Resource" error when the program runs. Is there some parameter I need to set in the device properties in order to create these targets Or is this format just not supported on the 360 As far as I could tell, you generally need to use this format for HDR lighting, if I am wrong and I could easily be using some other format, then I guess I will do that instead. Thanks for the help I don't believe that format is supported, though I could be wrong ...Show All
