请教创建进程后，得到这个进程的窗口hwnd

自己实现了

不知道这个代码有什么错误，暂时没过多的测试

void CdemoDlg::run_proc(void)

{

	CString szFilePath;

	szFilePath.Format(_T("C:\\windows\\notepad.exe"));



	STARTUPINFO strinfo; 

	memset(&strinfo,0,sizeof(STARTUPINFO));//这句不可少

	strinfo.cb=sizeof(STARTUPINFO);

	::GetStartupInfo(&strinfo);

	strinfo.wShowWindow=SW_SHOWNORMAL;

	strinfo.dwFlags=STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;



	PROCESS_INFORMATION Process_Info;

	CreateProcessW(szFilePath,NULL,NULL,NULL,false,NULL,NULL,NULL,&strinfo,&Process_Info);



	WNDINFO wndf;

	wndf.dwProcessId=Process_Info.dwProcessId;

	wndf.hWnd=NULL;

	int x=0;

	while(!wndf.hWnd&&x<1000)

	{

		EnumWindows(EnumWndProc,(LPARAM)&wndf);

		Sleep(10);

		x++;

	}

	TRACE("x=> %d",x);

	//WaitForInputIdle(Process_Info.hProcess, INFINITE);



	WINDOWPLACEMENT wpment;

	wpment.length=sizeof(wpment);

	::GetWindowPlacement(wndf.hWnd,&wpment);

	wpment.showCmd=SW_SHOWMAXIMIZED;

	::SetWindowPlacement(wndf.hWnd,&wpment);

	TRACE("handle ==>%x id ==>%x ==>%x\r\n",Process_Info.hProcess,Process_Info.dwProcessId,wndf.hWnd);

}



BOOL CALLBACK EnumWndProc(HWND hwnd,LPARAM lParam)

{	

	if(!::IsWindow(hwnd))

		return true; //不是窗口，直接返回，查找下一个

	if(!::IsWindowVisible(hwnd))

	DWORD dwProcessId;

	GetWindowThreadProcessId(hwnd, &dwProcessId);
