    Searching Windows For Windows

    Hi, so basically I've got a process. In that process there is a list of running windows. I want to search ALL of the windows in that process for a certain child window. The problem is I'm not quite sure how to go at this. I'm trying to do a EnumWindows() and a EnumChildWindows() in its PROC. The reason I'm doing this is because I don't know the name of the window, or what text the window will have (if any). Once I find this certain child window I would like to somehow obtain the name of its parent window. Here is what I'm trying/have so far:

    BOOL foundWindows = FALSE;
    HWND hMessageWindowATL = 0;
    BOOL CALLBACK EnumChildWindows(HWND hwnd, LPARAM lParam) {
    	hMessageWindowATL = FindWindowEx(hwnd, NULL, "InputWindow", NULL);
    	if (hMessageWindowATL) {
    		foundWindows = TRUE;
    		return FALSE; // stop the enumeration
    	return TRUE;
    // ^ continue enumerating if InputWindow could not be found as a child window of EnumParents enumerated window (hwnd)
    BOOL CALLBACK EnumParents(HWND hwnd, LPARAM lParam) {
    	EnumChildWindows(hwnd, &EnumChildWindows, NULL);
    	if (hMessageWindowATL)
    		return TRUE;
    	return FALSE;
    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    if (!foundWindows)
    			EnumWindows(&EnumParents, NULL);
    if (!hMessageWindowATL)
    			return 0;
    // do stuff because the target window was found
    This was an example I just cooked up, the original code is too long and confusing lol. If you need anything else let me know. Thanks.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
