Solution 1

This is probably what you are looking for: MiniDumpWriteDump[^], good luck.

Please note that creating full memory dumps might take a longer time and it might create quite a large file, so handle with care.

I try.. but nothing is written to the file

C++

case IDC_BUTTON2:
hFile = CreateFile( TEXT("minidump.dmp"), GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL );
	
  if( hFile!=NULL &&  hFile!=INVALID_HANDLE_VALUE )
  {

  MINIDUMP_EXCEPTION_INFORMATION eInfo;
  eInfo.ThreadId = GetCurrentThreadId();
  eInfo.ExceptionPointers = NULL;
  eInfo.ClientPointers = FALSE;

  MiniDumpWriteDump( GetCurrentProcess(), GetCurrentProcessId(), hFile, 
	  MiniDumpNormal, &eInfo, NULL, NULL);
 
MessageBox(hDlg,L"MiniDumpCreate",L"Minidump",MB_OK);

CloseHandle( hFile ); }
