Image Zoom

[marco]

I'm a newbie and i'm doing a little application that open image. I don't
understand what i've to do to have a zoom of an image...i don't know where's
the error. If anyone know a simple code tell me the url :O)
private void Zoom200_Click(o bject sender, System.EventArg s e)

{

PictureBox.Widt h = PictureBox.Widt h + (PictureBox.Wid th * 2);

PictureBox.Heig ht = PictureBox.Heig ht + (PictureBox.Hei ght * 2);

Ridisegna();

}


private void Ridisegna(){

PictureBox.Size Mode = PictureBoxSizeM ode.StretchImag e;

if ((PictureBox.Im age.Height>= PictureBox.Heig ht )||(PictureBox. Image.Width

= PictureBox.Widt h)){

vScrollBar.Maxi mum = PictureBox.Heig ht + hScrollBar.Heig ht;

hScrollBar.Maxi mum = PictureBox.Widt h + vScrollBar.Widt h;

hScrollBar.Valu e = 0;

vScrollBar.Visi ble = true;

hScrollBar.Visi ble = true;}

else{
vScrollBar.Visi ble = false;

hScrollBar.Visi ble = false; }

The error is that i don't see horizontal and vertical bar when the image is
bigger than picturebox

Try putting the PictureBox control into a Panel and set the Panels
AutoScroll property to true. Now, the scrollbars should be added to the
Panel automatically when the PictureBox is larger than the Panel.
