[C#][WinForm]如何取得當前視窗
網友問題，自己簡單實做記錄。
引用user32.dll API即可達到該需求。
參考GetForegroundWindow Function
[DllImport("user32.dll")]
private static extern Int32 GetForegroundWindow();
[DllImport("user32.dll")]
private static extern Int32 GetWindowText(Int32 hWnd, StringBuilder lpsb, Int32 count);
private void Form1_Load(object sender, EventArgs e)
{
Timer mytimer = new Timer();
mytimer.Tick +=new EventHandler(mytimer_Tick);
mytimer.Start();
}
private void mytimer_Tick(object sender, EventArgs e)
{
GetCurrentWindow();//取得活動視窗
}
private void GetCurrentWindow()
{
Int32 handle = 0;
StringBuilder sb = new StringBuilder(256);
handle = GetForegroundWindow();
if (GetWindowText(handle, sb, sb.Capacity) > 0)
{
label1.Text = "視窗標題:" + sb.ToString();
}
}
