Thread: Child looses focus in a couple of seconds.

I am using this code

Code:

DWORD WINAPI aeThread(LPVOID lpVoid)
{
   HWND hwnd = CreateWindowEx(0, "AEdit", "In-program Editor",
                              WS_VISIBLE | WS_CAPTION | WS_THICKFRAME,
                              100, 100, 600, 370,
                              HWND(lpVoid), NULL, GetModuleHandle(NULL), NULL);
   if(!hwnd) Quit(0, "Creation of AEdit window failed.");
   MSG aeMes;
   ZeroMemory(&aeMes, sizeof(MSG));
   while(GetMessage(&aeMes, NULL, 0, 0)) {
      TranslateMessage(&aeMes);
      DispatchMessage(&aeMes); }
   return 0;
}

to create a child window. Everything works fine, except for the fact that every time my child (or one of my child's children) gets focus, it looses it in a couple of seconds. Why is this?

Are you doing any processing on a timer?

You can use Spy++ to capture messages - which can give you clues as to what is triggering any focus messages.

No, no timer. If by Spy++ you mean WinSpy++, then I have no idea as how to catch messages.

Oh, I see, you where refering to MS-Spy++. The only messages getting sent are WM_SETFOCUS and WM_KILLFOCUS, and their associated messages. Nothing fishy.

The focus is given to the parent window.
The parent recives WM_SETFOCUS at the same time the child recives WM_KILLFOCUS.
