I try to get notified when a new window is created. To accomplish that i use a global windows hook like that:
LRESULT CALLBACK ShellHookProc(int code, WPARAM wParam, LPARAM lParam)
{
if(code == HSHELL_WINDOWCREATED) {
HWND hWindow = (HWND)wParam;
WCHAR wndText[255];
GetWindowText(hWindow, wndText, 255);
MessageBox(nullptr, L"WindowCreated", wndText, MB_OK);
}
return CallNextHookEx(nullptr, code, wParam, lParam);
}
__declspec(dllexport) void __stdcall initHooking()
{
HHOOK gShellHook = SetWindowsHookEx(WH_SHELL, ShellHookProc, GetModuleHandle(L"HookDll.dll"), 0);
if(gShellHook == nullptr) {
std::wstringstream strm;
strm << L"Error setting hook: " << GetLastError();
MessageBox(nullptr, strm.str().c_str(), L"", MB_OK);
}
}
The hook actually works, but it gets called like 10 times for the same window with the same window handle. Is that normal? And if so whats the reason?
