picture viewer zoom and more

[Siten0308]

Hello,

I am wondering, this is probably easy question but a got a nice hard one for everyone
on with the questions:
1. i have a picture image, i tell it to zoom in using this code below

pictureBox1.Width += 2;
            pictureBox1.Height += 2;

the only problem is, it makes the picture box zoom in, meaning the picture box gets bigger and bigger covering the form and other objects/controls which makes me laugh a little. my question is, how do i keep the picture box from getting so big and staying the same size while actually zooming in on the picture itself??

2. how do you draw a rectangle around the picture, for example you left click hold it (that would be mousedown event right?) and drag over the picture to display a rectangle around the picture, capturing 4 points (x, y).

Let me know,

Thanks
