使用AnimateWindow显示子窗体时不能显示子窗体上的控件。
Form2 a = new Form2();
int x = Screen.PrimaryScreen.WorkingArea.Right - a.Width;
int y = Screen.PrimaryScreen.WorkingArea.Bottom - a.Height;
a.Location = new Point(x, y);//设置窗体在屏幕右下角显示
AnimateWindow(a.Handle, 1000, AW_SLIDE | AW_ACTIVE | AW_VER_NEGATIVE);
贴出你的代码或者参考:http://www.jb51.net/article/34939.htm
看看是不是
public FormTitle()
{
InitializeComponent(); //你不小心把这一行删除了
this.StartPosition = FormStartPosition.CenterScreen;
}
