我正在尝试将按钮单击发送到另一个应用程序,在本例中是一个Java应用程序。我正在使用FindWindow()。我可以使用SendKeys.SendWait()将密钥发送到应用程序窗口,但是当我尝试单击Register按钮时,Findwindowex()会为按钮指针返回0。我唯一的想法是,FindWindowEx()可能不喜欢父和子句柄相同,但在这种情况下没有子窗口句柄。任何帮助将不胜感激。

答案 0 :(得分:0)
如果lpClassName
为NULL
FindWindow
,则会仅通过lpWindowName
(窗口标题)搜索该窗口。如果特定窗口的类是可变的,
我的问题是,你给出了正确的窗口标题吗?
您可以使用流程资源管理器找到它 - https://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
如果能解决问题,请告诉我。
如果它没有帮助 - 我们找到了以下代码段:
private void SendKeysToWindow(string WindowName, string KeysToSend)
{
IntPtr hWnd = FindWindow(null, WindowName);
ShowWindow(hWnd, SW_SHOWNORMAL);
SetForegroundWindow(hWnd);
Thread.Sleep(50);
SendKeys.SendWait(KeysToSend);
}
