• Visual Basic Compiler does not warn when assigning to readonly property

  I am maybe a newbie in VB .Net programming, but two recent incidents lead me to believe there are bugs in the VB compiler. Today, I finally discovered that compiler did not warn me even though, I was assigning a value to a public readonly property. Not only that, I have configured the project's compile settings to treat all warnings as errors. Option strict is on. This experience is similar to an earlier one where I was puzzled how in the world was it possible that a protected readonly structure variable in a mustinherit base class was indirectly overwritten in a totally unrelated calculation. Not only that, when I changed the structure declaration to a class declaration it would still overwrite the protected readonly variable. Th ...Show All

• .NET Development DataTable is loaded very slow if there are two threads doing the same thing

  Hi, Here is my problem very short: Loading an oledb table data takes a fair amount of time, if there is only one thread that loads a table with data. If there are two of them, each loading its own table, loading takes unacceptable time. Now very long: I've written an oledb supplier (ATL) for a proprietary data source (it's not a database, it a server that exposes data on the network using an xml protocol). So far so good. I tested the oledb supplier with various methods, including a C++ program (not .net, mfc and ATL for oledb) that launched 10 threads to query the same data. It worked without problems. Now my job is to make a client program that does something with the exposed data. Unfortunately I have to use C# to do that, and of cour ...Show All

• Visual Studio Express Editions Save

  How do I Save a file with out calling the dialog box, at the moment I can SaveAs the file(with dialog box) but what I'm after is when you click just save it just saves the file that is opened in its original format with any alterations that have been made. The program is a cut down version of a text editor. When you use the dialogbox you presumably have something like: If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then ' some code to save the file End If To save it without the dialogue then just put the code you run there into your Save button click event, replacing the dialog.filename property with the name of the file you opened originally.

• SQL Server Freeze panes when report is exported to Excel

  I am using RS 2005 and emailing reports in Excel to my end users. Is it possible to set the report in VS.Net to freeze the panes so that the user will always see the column A when they scroll to the right once they view the report in Excel I have the feeling the answer is no, but I thought I'd check. Hi, there is a property named FixedHeader. I didn’t try that this deep yet (only for table header) , but it would be worth a try. I guess you will your own rendering extension as the rendering for Excel didn’t brought back the right results with fixed headers for me (worked well in HTML, but not in Excel) HTH, jens Suessmeyer. --- http://www.sqlserver2005.de --- ...Show All

How can I do in XNA Thanks in advance Lluis If this is a 3D application, you should be able to do it pretty easily using a custom shader, loading the texture dynamically. If it's a 2D application, I think I'd just have more than one copy of the sprite texture already mapped with the different grains. Bill ...Show All

• .NET Development Target the Framework version and Redirect Assembly Bindings from 2.0 to 1.1

  Dear all, I have encountered a problem of "DragDrop registration failed" problem in my .NET 1.1 dll because of the assembly binding is always going to .NET 2.0. (I realized the related attribute [STAThread], however, there's no Main() in my C# libraries) Therefore I tried to specifiy the runtime version and redirect those bindings in MyModule.dll.config. The binded assemblies, however, are still in .NET 2.0, according to both VS.NET 2003's output log and VS.NET 2005's fuslogvw. Meanwhile, they also logged compiling and linking processes. At that stage, linked assemblies are in version 1.1 correctly. My question is, does it means that configurations of runtime version and assembly binding redirection do not work backwa ...Show All

• Visual C++ problem with /NODEFAULTLIB linker option

  Hello, I'm trying to compile a C++ code with /clr option and remove all references to the default library. I want to only analyze the output code and do not need to run it.

• Visual Studio Team System Proxy Configuration for Dummies

  Hi, my coworker and I just can't get the proxy setup straight. I started a test setup where I have one TFS and one client. The client can connect directly to the TFS without a problem, now I want to do the same, but use a proxy (we will later do this between remote locations with a slow connection). I have some really basic questions and I guess I just did not understand how exaclty the proxy works. a) Where do I have to install the proxy portion (the setup in the proxy folder on the TFS CD) I assume that this goes on the machine that is the client to the actual TFS server. Like this: TFS Server ----WAN connection---- Proxy &Client (VS2k5) on same PC Correct b) In the proxy.config file, is it correct to enter the name of the ...Show All
