OK. You asked for it. Below is a short C program which will check the state of the NumLock key and synthesize a keydown/keyup sequence of the NumLock key if it's down. Works on my box, which is Win2K, but I'm led to believe from the documentation that it should work with any 32-bit implementation of windows.
To build it, copy-paste the following source into a file (e.g. "numlockoff.c") then run gcc on it (e.g. "gcc -o numlockoff numlockoff.c"). Then add that to a convenient location on your client systems and add a call to it in your X startup script.
#include <stdio.h> #define _WIN32_WINNT 0x0500 #include <windows.h>
int main() { INPUT pInput[2];
if (GetKeyState(VK_NUMLOCK) == 1) { pInput[0].type = INPUT_KEYBOARD; pInput[0].ki.wVk = VK_NUMLOCK; pInput[0].ki.wScan = 0; pInput[0].ki.dwFlags = 0; /* Nill for keydown */ pInput[0].ki.time = 0; pInput[0].ki.dwExtraInfo = 0;
pInput[1].type = INPUT_KEYBOARD; pInput[1].ki.wVk = VK_NUMLOCK; pInput[1].ki.wScan = 0; pInput[1].ki.dwFlags = KEYEVENTF_KEYUP; pInput[1].ki.time = 0; pInput[1].ki.dwExtraInfo = 0;
if (SendInput(2, pInput, sizeof(INPUT)) == 0)
{
fprintf(stderr, "Error: SendInput failed. NumLock was not turned off.\n");
}
}
}
