Answer 1

What you are asking about is called a rollover image.

You'll need an image editing program to achieve what you are after. http://www.gimp.com and http://www.irfanview.com are free ones.

I don't think VB will cut it up for you on Load, but maybe you can trick it out like this.

Set your frame for the picture..let's say it's 4" x 4"

Make 4 - 2" x 2" frames and place them over the top (bring to front) of the first frame to create your 4 pieces. Make them transparent and don't put anything in them so on Load, you should see the picture behind them.

Then make your mouseover events on the 4 frames.

Hope that helps

I'm not sure how to do it using VB, but you could use an Imagemap in HTML. This is how its normally done. If you want each element to act independently when doing a mouse over or mouse down event, then you will need to overlay separate images over your image map and place events on those.

The functionality you're looking for is in the Graphics class. Not sure why you'd want to do it that way, but here's a place to start (c#, but easy enough to get to VB):

private Bitmap sliceImage(Bitmap patient)
{

Rectangle sliceRec = new Rectangle(this.Location, this.Size);
Bitmap theSlice = new Bitmap(sliceRec.Width, sliceRec.Height);

Graphics g = Graphics.FromImage(theSlice);
g.DrawImage(patient, sliceRec, Location.X, Location.Y, 5, 5, GraphicsUnit.Pixel);
g.Dispose();
return theSlice;

} // close private void sliceImage(Image patient)
