核心提示：this.Invalidate();}private void Form1_MouseUp(object sender, MouseEventArgs e){IsDown = false;}~Form1(){SelectObject(g_hdc, g_oldb);SelectObject(g_hdc, g_oldp);

this.Invalidate();

}

private void Form1_MouseUp(object sender, MouseEventArgs e)

{

IsDown = false;

}

~Form1()

{

SelectObject(g_hdc, g_oldb);

SelectObject(g_hdc, g_oldp);

DeleteObject(g_hBrush);

DeleteObject(g_hPen);

BufferGraphics.ReleaseHdc(g_hdc);

}

}

}
