[Mingw-users] Application runs from MSYS but not from CMD

[Quintus <su...@gm...>]

Hi there,

First off, I'm quite new to the C world, but I try to learn what I can 
get...
So, here's my problem: I've a small C program that simulates some mouse
input to Windows and if I run this from the MSYS shell it works quite well.
Now, if I try to run it from CMD or by double-clicking on the executable 
file,
nothing happens. I searched the web for that problem, but couldn't find any
reasonable help, so now I'm posting here...

That's a small sample program:
----------------------------------------
#define _WIN32_WINNT 0x0500
#include <windows.h>

int main(int argc, char *argv[])
{
  INPUT inps[2];
  MOUSEINPUT mis[2];
  inps[0].type = INPUT_MOUSE;
  inps[1].type = INPUT_MOUSE;
 
  mis[0].mouseData = 0;
  mis[0].dwFlags = MOUSEEVENTF_LEFTDOWN;
  mis[1].mouseData = 0;
  mis[1].dwFlags = MOUSEEVENTF_LEFTUP;
 
  inps[0].mi = mis[0];
  inps[1].mi = mis[1];
 
  SendInput(2, inps, sizeof(INPUT));
  return 0;
}

----------------------------------------
I'm running on Windows Vista and didn't pass any compilation
options to gcc, I just did "gcc abc.c" and than ran "a.exe".

Can anyone explain this to me?
