   There is no source code available for the current location....
  Hey folks!I'm having a bit of trouble with debugging a programme, and I was wondering if anyone could offer me a helping hand.I'm stepping through the programme, and everytime i come to a ZeroMemory() call, such as:ZeroMemory(&d3dpp, sizeof(d3dpp));I obtain an error box stating:There is no source code available for the current location.This one has me stumped, as I've had this working in the past without trouble. If full source code is needed I'll post it. :)Thanks in advance!   
  ZeroMemory is a macro. It maps to RtlZeroMemory in <winbase.h>RtlZeroMemory is a macro. It maps to memset() in <winnt.h>memset() is a standard C library function. I don't think Visual Studio includes the full C std lib source code, but it's not like the code for memset is rocket science.;  memset() is also potentially a compiler intrinsic depending on your build settings. In other words, MSVC may replace a call to memset() with assembly code that accomplishes what memset() does.   ;  Did you expect to find the source code for ZeroMemory ? If so the provious post have solved your problem.But i though maybe you just didnt notice that F11 was used to 'step into' but if you use F10 you'll just 'step over' and the problem wont occur anymore. (sayin that since this is a beginner forum isnt it)
