      • All that I am looking for is to start a new class file with all of my favorite 'using namespace' references ready to go, But it changes the namespace references. Either I am using it wrong, doesn't work the way I think it should, or it is not working properly. Creating templates is simple enough, just File->Export Template. Select "Project Template" or "Item Template"

      • I've written an unmanaged DLL in C++ and I need to call back into a single function on the managed side. My solution was to accept a function pointer through the DLL interface and invoke said pointer as necessary using __stdcall. I'm not that experienced with INTEROP and I don't understand how this is possible without the use of a function pointer. Is there some form of "magic" via .Net

      • How do I "disable" a method from a base class in a derived class I could throw an exception in the derived class, but that doesn't alert me until run time. As an example, suppose Class A has three methods X(), Y(), and Z() and then I derive classes B, C, D, and E from A. But, I don't want class D to have access to method Y(). I know I could make a class A1 with only X()

      • Hi I am trying to use C# to find out if a particular file is an MS Word document without having to rely on the file extension. I'm sure there must be a way to do this as Windows manages it. For instance, if I create a Word document and then save it, then remove the extension and double click it, the file it automagically opens in Word. It works for Excel as well. Any assistance would be very much
