• .NET Development Access Database and x64 OleDB Connect

• Visual Studio MsBuild SourceSafe integration

  Hi, Can anyone point me towards how MSBuild can be used to get the latest version(s) of project(s) from VisualSourceSafe and perform an automated build process. We are trying to setup a automated build system for our various projects being worked on by multiple developers. So, we just want to take baby steps right now until we identify a process that works for us. -Vish The open source msbuildtasks have VSS support. I haven't used them yet, but they look pretty useful: http://msbuildtasks.tigris.org/ ...Show All

• Visual Basic Checking for optional parameters in a function

  I just seem to be generating questions today. I have a function (UpdateNode) which can be used to write back data to a database.  The function accepts a number of optional parameters depending on what the user wishes to change.  These Parameters are: StructureID - Mandatory (key field) Description (String) Name (String) ParentID (Int) isTeam (Boolean) Where no parameter is specified, then I don't wish to touch what was already in that column on the database.  I have managed to figure out how to check if all the parameters have been given except for the boolean values.  There are two valid options for the isTeam- True or f ...Show All

• Windows Forms Usage of two windows forms

• Windows Forms When to use User32.dll and how?

  Can someone tell me more about User32.dll How does it work and how can I use it I know that I must have this on my program: [DllImport( "User32.dll" )] But all the rest is that what I can't understand.

• .NET Development I wish you could Serialize the XslCompiledTransform?

  The new XslCompiledTransform has great performance once it is compiled but what path can you take if you have hundreds of stylesheets to compile. We have converted a java CMS system to C#/ASP.NET. The old application represented each site design as xslt. The old designs are working great in the new implementation but my major bottleneck remains compiling the transforms. Once the transform is compiled it is then stored in the Cache object but this solution is still tapping out the cpu on the servers because most incoming request require a different design. Also the system is clustared so if the load balancer directs you to a diff server you h ...Show All

• Visual C++ Windows XP Password character.

  Hi, Dont know if this is the correct forum, but since I didnt get any answers elsewhere, I'm posting it here as well The Problem: On some machines, my password field displays the password character as the "dot" - which is XP standard, and on other machines it dispays small square boxes.

• .NET Development Making dataset instances invisible to COM

  Hi There, I've got a C# assembly that's marked for COM Interop Registration. It contans a dataset definition. When I look at the TLB file generated for the assembly, the object is included. (for example, if the dataset is called AlphaDS, there's a default interface generated for the dataset called _AlphaDS, and a coclass entry for AlphaDS) I'd like to mark the Dataset as COMVisible(false) so it doesn't show up in the TLB. I could mark the generated .cs file for the dataset with this attribute, but this file is auto-generated and the changes are lost each time I re-build the assembly. Anyone have any ideas Thanks ...Show All
