How does MFC judge whether a program (such as Thunder) is running?

Simply put, you can traverse the processes, then compare the process names, and enumerate the processes using Process32First and Process32Next 32 Next.

Simple, you can directly use HWND hWnd = FindWindow(NULL, _T ("Thunder 7")); Function. If NULL is returned, it is not found. . It is best to use FindWindow combined with Microsoft Spy++ to judge the specific information of the window. .

Spy++ generally comes with tools to install Visual Studio.
