Zoom Image C# Pocket PC

[Guest]

I'm a newbie and i'm doing a little application in C# for a Pocket PC 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(object sender, System.EventArgs e)

{

PictureBox.Width = PictureBox.Width + (PictureBox.Width * 2);

PictureBox.Height = PictureBox.Height + (PictureBox.Height * 2);

Ridisegna();

}

.......................


private void Ridisegna(){

PictureBox.SizeMode = PictureBoxSizeMode.StretchImage;

if ((PictureBox.Image.Height>= PictureBox.Height )||(PictureBox.Image.Width

= PictureBox.Width)){

vScrollBar.Maximum = PictureBox.Height + hScrollBar.Height;

hScrollBar.Maximum = PictureBox.Width + vScrollBar.Width;

hScrollBar.Value = 0;

vScrollBar.Visible = true;

hScrollBar.Visible = true;}

else{


vScrollBar.Visible = false;

hScrollBar.Visible = false; }

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

I totally overlooked the PPC reference this time around. Ok, so the
AutoScroll won't work here. A good code sample for implementing scrolling
content in the Compact Framework can be found here.

You, obviously, need to tweak it out a bit, but it should give you a good
enough start.
