VB 請問如何穫取一箇無標題的窗口句柄?
請問:如何穫取一箇無標題的窗口句柄?知道他的應用程序名稱。 
謝謝指點

------解決方案--------------------
方法一:調用EnumWindows,枚舉所有窗口句柄,然後在枚舉過程中,調用GetModuleFileName,穫取該窗口句柄的進程名,如果等於你已經知道的進程名字,那這箇窗口就是你想要找的窗口瞭。 
方法二:用工具找到這箇程序的類名(一般程序類名都是不一樣的),然後用FindWindow就可以找到這箇窗口的句柄。 
如果不明白,請繼續提問。

如果牠是前颱窗口可用GetForegroundWindow或GetFocus 
或用GetCursorPos加WindowFromPoint用鼠標選 
或用樓上説的枚舉
