如何将屏幕锁定

[feels30000]

FORM上的部分操作使FORM有闪烁，怎样使屏幕锁定，当操作完成后再将FORM重画
就象DELPHI中的LockWindowUpdate

用WIN32 Api
LockWindowUpdate

VB的例子

[DllImport("user32.dll",CharSet=CharSet.Auto)]
public static extern bool LockWindowUpdate(
IntPtr hWndLock // handle to window
);

=================
private void button1_Click_1(object sender, System.EventArgs e)
{
LockWindowUpdate(this.Handle);
//do something
LockWindowUpdate((System.IntPtr)0);
}
