I made this today for a coworker. It is meant to have a properly calculator-y icon, placed into the quick launch bar, and then used to bring up the calculator.

features include:
* only brings up one instance of the calculator.
* if calculator is not running, it runs it.
* if calculator is running, and is not topmost, it'll make it topmost
* if calculator is running, and it is topmost, it'll make it non-topmost


#include 

int __stdcall WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShow)
{
HWND hWndCalc=FindWindow(NULL,TEXT("Calculator"));
if(hWndCalc)
{
if(GetWindowLong(hWndCalc,GWL_EXSTYLE)&WS_EX_TOPMOST)
{
SetWindowPos(hWndCalc,HWND_NOTOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
ShowWindow(hWndCalc,SW_RESTORE);
}
else
{
SetWindowPos(hWndCalc,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
ShowWindow(hWndCalc,SW_RESTORE);
}
}
else
{
ShellExecute(NULL,TEXT("open"),TEXT("calc.exe"),NULL,NULL,SW_SHOW);
}
return(0);
}

I got one of them Microsoft Natural Keyboard 4000's with the calculator button. I have the button set to launch XCalc, and it works about the same.

I think XCalc only runs single-instance and moves to the front when it's re-launched, so it's a bit from the keyboard driver and a bit from the calculator that's giving me that functionality.
