Method ScriptBlockInput

Source/script.cpp:11608–11623

ResultType Line::ScriptBlockInput(bool aEnable)
// Adapted from the AutoIt3 source.
// Always returns OK for caller convenience.
{
	// Must be running Win98/2000+ for this function to be successful.
	// We must dynamically load the function to retain compatibility with Win95 (program won't launch
	// at all otherwise).
	typedef void (CALLBACK *BlockInput)(BOOL);
	static BlockInput lpfnDLLProc = (BlockInput)GetProcAddress(GetModuleHandle("User32.dll"), "BlockInput");
	// Always turn input ON/OFF even if g_BlockInput says its already in the right state.  This is because
	// BlockInput can be externally and undetectibly disabled, e.g. if the user presses Ctrl-Alt-Del:
	if (lpfnDLLProc)
		(*lpfnDLLProc)(aEnable ? TRUE : FALSE);
	g_BlockInput = aEnable;
	return OK;  // By design, it never returns FAIL.
