Help! Some unknown error during Compiling

[Vikas Sihag]

The Code Given Below is woring correctly during debug.
But does not work during compiling, It doesn't even shows an error.
[code=cpp]
private void pictureBox1_Mou seUp(object sender, MouseEventArgs e)
{
ep.X =e.X;
ep.Y =e.Y;
}
private void pictureBox1_Pai nt(object sender, PaintEventArgs e)
{
Pen p=new Pen(Color.Black ,2);
Graphics g = e.Graphics;
g.DrawLine(p,sp .X,sp.Y,ep.X,ep .Y);
}

private void pictureBox1_Mou seDown(object sender, MouseEventArgs e)
{
sp.X =MousePosition. X;
sp.Y = MousePosition.Y ;
}[/code]

When you say compiling, do you mean in the release version? And how are you using the release exe, if this is the case? Sometimes copy/pasting to a computer will not work, sometimes it will.

Could you explain a little more on what its doing that indicates it is not working?
Is it failing on the compile?
Did it compile and wont run?
?
