[英]Get Active Window of .net application
I have an application named ProLaunch.exe. 我有一个名为ProLaunch.exe的应用程序。 I want to get the active window in it and close it if the user is not performing any operation for the speicified period.
我想在其中获取活动窗口,如果用户在指定时间内未执行任何操作,则将其关闭。 A timer in the application will be used for this purpose.
应用程序中的计时器将用于此目的。
How can I get the active window and close it? 如何获得活动窗口并关闭它?
If I understand the question correctly, you can use the Win32 API GetActiveWindow for this. 如果我正确理解了该问题,则可以为此使用Win32 API GetActiveWindow 。 This should work in both Forms and WPF apps.
这应该在Forms和WPF应用程序中都可以使用。
[DllImport("user32.dll")]
static extern IntPtr GetActiveWindow();
[DllImport("user32.dll")]
public static extern int SendMessage(int hWnd, IntPtr msg, int wParam, int lParam);
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_CLOSE = 0xF060;
// close the active window using API
private void FindAndCloseActiveWindow()
{
IntPtr handle=GetActiveWindow();
SendMessage(handle, WM_SYSCOMMAND, SC_CLOSE, 0);
}
