Do you know one? Please contribute it!
From MSDN: The GetProcessImageFileName function returns the path in device form, rather than drive letters. For example, the file name C:\Winnt\System32\Ctype.nls would look as follows in device form:
This can be used in place of the GetModuleFileName call, which doesn't work on processes that haven't been loaded by the current one.
Tips & Tricks:
I found this to be more comprehensive than GetModuleFileNameEx. Didnt need to enumerate windows or modules
uint pid = 0;
StringBuilder fileName = new StringBuilder(2000);
/** get the handle for point under cursor **/
IntPtr hWnd = WindowFromPoint(pt);
/** Need to get the process ID from handle under cursor **/
GetWindowThreadProcessId(hWnd, out pid);
/** Hook into process **/
IntPtr pic = OpenProcess(NativeMethods.ProcessAccessFlags.All, true, (int)pid);
/** This gets the filename of the process image. Path is in device format **/
GetProcessImageFileName(pic, fileName, 2000);
Retrieves the name of the executable file for the specified process.
