It seems that calling Windows API functions from Axapta is viewed as some sort of mysterious magic by most Axapta developers. Unfortunately, there are times when you need to do something that requires tight integration with functionality that exists outside of the system. While there are other methods of interfacing between bits of code, including COM, XML-RPC, or even .NET, using the Windows API can sometimes be very efficient, and powerful.

For beginner WinAPI coders who are also Axapta programmers, with at least some programming experience in C or C++, I felt it might be better to answer a question from my colleagues about calling WinAPI calls from Axapta, outside of those already wrapped by the WinAPI:: or WinGDI:: classes.
