Hi, lilmeanman / FEARHQ,

here is a C program which will do the job...
Compile from DOS prompt with command "cl click.c"
Run the resulting CLICK.EXE from DOS prompt attaching the button name (e.g. "ok") as command parameter.

// CLICK.C -- written by bilbo -- 15feb05

#include <windows.h>
#include <stdio.h>
#pragma comment(lib, "user32")

#define WM_CLICK 0xF5

BOOL CALLBACK
EnumWindowsProc(HWND hwnd, LPARAM caption)
{
	char name[128];

	if (GetClassName(hwnd, name, 127) && !strcmp(name, "Button")) {
		GetWindowText(hwnd, name, 127);
		if (!stricmp(name, (LPSTR)caption)) {
			printf("Found Button with handle %x\n", hwnd);
			SendMessage(hwnd, WM_CLICK, 0, 0);
			return FALSE;  // done
			}
		}

	EnumChildWindows(hwnd, EnumWindowsProc, (WPARAM)caption);
	return TRUE;
}

void
main(int argc, char **argv)
{
	if (argc != 2) {
		printf("usage: %s button_caption\n", argv[0]);
		return;
		}

	EnumWindows(EnumWindowsProc, (LPARAM)argv[1]);
}

Strangely enough the message WM_CLICK is not defined in Microsoft includes!!!
So I have defined it at start of the program.

To test the program, you can run Calculator: in that app, each key is a different button... You can press calc keys remotely (e.g. "click 1" "click +")...
