復制代碼 代碼如下:
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int Width, int Height, int flags);
/// <summary>
/// 得到當前活動的窗口
/// </summary>
/// <returns></returns>
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern System.IntPtr GetForegroundWindow();
哪個窗體想要置頂,在Form_Load中加上
SetWindowPos(this.Handle, -1, 0, 0, 0, 0, 1 | 2); //最後參數也有用1 | 4
具體說明,看API函數說明
如果是用點擊一個按鈕後彈出新窗體,並置頂,則:
復制代碼 代碼如下:
Form2 frm = new Form2();
frm.Show();
SetWindowPos(GetForegroundWindow(), -1, 0, 0, 0, 0, 1 | 2);
這樣,新打開的窗體就是置頂了
