Advertisements As far as I understand .NET concepts, the source code is first translated into an Assembly (IL code+meta data), which is compiled to machine code on the target machine with the CLR’s JIT compiler. However I cannot really match these concepts to what I see when working on a C# project. When I build… Read More Understanding .NET compilation
Advertisements The prototype of GetCurrentDirectory DWORD GetCurrentDirectory( [in] DWORD nBufferLength, [out] LPTSTR lpBuffer ); DWORD is unsigned long, LPTSTR is a pointer to wchar buffer in Unicode environment.

For some reason, the output file contains a load of random trash bytes interspersed with the key codes I want to log.
