Hi there! I've written a little DLL (does absolutely NOTHING except a message box). When I compile this code with my old MSVC2003 everything works fine: I start the TestApp and the Message box appears. But when I compile the same code with MSVC2005 and I start the TestApp I get the following Error message: (I don't know how to translate it properly) ;-) Something like: the funktion XYZ's entry point could not be found in happy.dll Both DLL projects were created with the wizard using the same settings. How can this be?
