Method ScriptSendMessage

Source/script2.cpp:2881–2899

ResultType Line::ScriptSendMessage(char *aMsg, char *awParam, char *alParam, char *aControl
	, char *aTitle, char *aText, char *aExcludeTitle, char *aExcludeText)
{
	HWND target_window = DetermineTargetWindow(aTitle, aText, aExcludeTitle, aExcludeText);
	if (!target_window)
		return g_ErrorLevel->Assign("FAIL"); // Need a special value to distinguish this from numeric reply-values.
	HWND control_window = *aControl ? ControlExist(target_window, aControl) : target_window;
	if (!control_window)
		return g_ErrorLevel->Assign("FAIL");
	// Use ATOI64 to support unsigned (i.e. UINT, LPARAM, and WPARAM are all 32-bit unsigned values).
	// ATOI64 also supports hex strings in the script, such as 0xFF, which is why it's commonly
	// used in functions such as this:
	DWORD dwResult;
	if (!SendMessageTimeout(control_window, ATOU(aMsg), ATOU(awParam), ATOU(alParam)
		, SMTO_ABORTIFHUNG, 5000, &dwResult)) // Increased from 2000 in v1.0.27.
		return g_ErrorLevel->Assign("FAIL"); // Need a special value to distinguish this from numeric reply-values.
	// By design (since this is a power user feature), no ControlDelay is done here.
	return g_ErrorLevel->Assign(dwResult); // UINT seems best most of the time?
