• Visual Studio 2008 (Pre-release) Circular dependency

  Hi I have data contract classes A and B which inherite from a base class. I send the base class in my method, using the known types attribute (in the base class) to reference the derived classes. However, if the base class is located in one assembly and the derived classes in another, trying to do this will cause a circular dependency error (I can't add the reference to the assembly). How do I resolve this Thanks Interesting... I'll think about this some more, but for now - can you try one of the other mechanisms for adding known types For example, could you add the known types in the operatio ...Show All

• .NET Development 64 bit compilation starts always with /D "Win32"

  This might be a  VS general issue but I decided to post it here: I am porting a project to AMD64 bit. After solving some poting issues I am facing the following problem: The compiler is started with /D "Win32" , although in the project configuration WIN64 is defined. I tried - to rebuild... no effect - to reload solution ... no effect In the vcproj file the defines are correct. I could upload a screeenshot if possible. The "by design" part refers to the issue of throwsing /D "Win32" to a 64-bit configuration.  The problem we are investigating is the discrepency between the build command ...Show All

• Visual Basic Initialization and Finalization of Modules and ClassLibs

  Is there a way to cause Modules and ClassLibs to run code automatically under their own power when they load Or is there a better way to do what I'm doing Module A Public requingInitialization as someType ... End Module In some other systems I'm familiar with you can say Unit A ... Initialization ... Finalization ... End. which makes it very nice because the user of the "unit" doesn't have to worry about what it needs to do to provide its services.

What I'd really like to be able to do is combox ...Show All

• Visual C++ App hogs CPU when mouse pointer moved over it
