• Visual Studio Express Editions Help Clearing All Textboxes and All Comboboxes

• Visual Studio Team System Who wants a FxCop VS2005 add-in?

  Hello, I have written a simple add-in for VS 2005 to enhance integration with the IDE for those who are not using the Team System version of the product. I am planning to release it to the open source community but I'm wondering whether there is much interest in doing so. Currently the add-in does the following things: Select one or more FxCop warnings in the Error List then right-click to copy C# code for SuppressMessage attributes to the clipboard. Select one or more FxCop warnings in the Error List then right-click in the code editor window to insert C# code for SuppressMessage attributes at the current insertion point. (Saves the work of copying to clipboard, then clicking back to the editor and pasting.) Double-click on ...Show All

• SQL Server Merge Replication not replicating updates

  I have an issue that is only occurring in a production environment. The architecture is filtered merge replication between two SQL Server 2000 SP4 databases. The publisher is standard edition and the subscriber is personal edition. The issue is that is I update certain rows on the subscriber the data is not replicated to the publisher. Inserts and deletes seem to replicate correctly. The issue is specific to certain rows in some tables. If I update other rows the updates replicate correctly. The subscription has been re-initialized once and it did not fix the issue. The replication process indicates that there was not data to merge and the subscriber updates remain and are at that point different form the publisher row values af ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Translating C# DirectX example to C++/CLI

  Hi,   I try to convert/use a DirectX C# sample in C++/CLI but got stuck on following C# statement:        vb = new VertexBuffer(typeof(CustomVertex.PositionColored), 3, device, Usage.Dynamic | Usage.WriteOnly, CustomVertex.PositionColored.Format, Pool.Default); How would you convert this statement to C++/CLI   I couldn't go farther than this.          vb = gcnew VertexBuffer(CustomVertex::PositionColored::GetType, 3, device, Usage::Dynamic | Usage::WriteOnly, CustomVertex::PositionColored::Format, Pool::Default);   Seems that I don't have the right equivalent expression for "typeof"...

• Visual Basic New Printform 1.0 Powerpack question

  My company currently uses NTsvr.ocx to run a window's form's application as a service. In these applications we have some form that are printed as Batch sheets for our printers to run jobs. This is done with the old vb6 printform method. Yes, this ocx no longer supported by Microsoft. Yes, this is not a good implementation. That is not my problem. My problem is I'm trying to upgrade the services into a VS 2005 Windows service and in doing so I'm losing the ability to use the VB6 printform method without the powerpack. I've installed the powerpack but I am still having issues. So far I've only been able to get the powerpack to print an active and open form. The problem is if the application is installed as a Windows service. There ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. kW X-porter is updated for 3ds Max 9

  I have finally had time to build and test the kW X-porter plug-in to export .X files from 3ds Max 9. This exporter does better than the DirectX SDK exporter (like, it actually does multiple animations), and has a few more bells and whistles than the PandaSoft exporter. Also, with 3ds max 9, the stock IGame.dll file is not overwritten, as the right version is included from Autodesk. http://www.mindcontrol.org/~hplus/graphics/kwxport.html Note: most users claim kW works fine for them, and some users get crashes. I can look at the crashes and fix them if I get a copy of the .max file. The e-mail for questions is found in the installed documentation. OK Mr. Watte, anyway thanks for the attention. I did the update with the version ...Show All

• SQL Server stored procedures, compile or not

  I am writing stored procedures to retrieve data from an OLTP application that will be adding several hundred thousand transactions a day. The user will be presented a screen to select up to a dozen or so search criteria; date range, color, size, processing plant, etc. They may select all criteria, one or two, or none. Currently I am creating a stored procedure "on the fly" by replacing temp vars with search criteria, compiling and executing. My option would be to compile the stored procedure, pass it parameters, and run the precompiled stored procedure. I am wondering, as the database is changing so much, if I am better off to compile the procedure every time it is run. Or if stored procedures are always the best way to ...Show All

• Windows Forms Can't sign assembly (ClickOnce: Publisher cannot be verified)

  I'm attempting to deploy a ClickOnce app and realize that I must sign the assembly as well as the ClickOnce manifests (AFAIK) to get rid of that "Publisher cannot be verified" and the Install and Don't Install buttons.  (someone correct me if I'm wrong here). The problem is, I am using the famous "Microsoft.Msdn.Samples.BITS" dll found here ( http://msdn2.microsoft.com/en-us/library/ms997639.aspx ) in the application.  When I sign the assembly within VS2005 and go to do a build, I get the following error: Error 1 Unable to emit assembly: Referenced assembly 'BackgroundCopyManager' does not have a strong name  This occurs in the BITS project that contains a reference to 'BackgroundCopyManager.dll'.  Unde ...Show All

• SQL Server WSUS MSDE Problem

  Hi All Im a new comer to the site and wsus. I inherited a functional wsus server it was great but due to a demand for improved reporting features I attempted to install the Wsus rollup reporting sample. Im uncertain as to how but I hashed up the installation to the extent that it corrupted the MSDE installation. It was suggested I remove wsus and reinstall. At this point I made another error. I was told that WSUS 3 had improved reporting features (and indeed it does, its infinitely better in that respect) so I signed up with Microsoft and downloaded the installation file. WSUS 3 uses SQL 2005 for Windows so my back up of the MDF & log files were rendered useless. I have since removed WSUS 3 reinstalled a fresh copy of WSUS Sp1 and run ...Show All

• Visual C# DLL shared by two application instances - How does this work?

  I'm fairly new to C#. I am developing an application that uses a multiport communication board that is supported by an older style DLL. The application code uses a statement : [DllImport("PCIDX.dll")] when declaring the DLL function prototypes. The application .exe and DLL's are located in the same directory. We plan to load an instance of the application for each port we wish to use. When the first application instance is loaded it makes a DLL call to get a handle for the adapter and is able to use this handle in subsequent DLL calls. When a second instance of the application is loaded, the open fails, indicating the adapter is already in use. No biggy, I just use the handle number obtained from the first application i ...Show All
