How do I create a map file? I need to stop a picture from going off the form... do i need a special program to do that?

Oh boy, this will be a long thread. You need to store the map in a 2d array. And then I guess just save the array as .map

Yeah, that's what i think Steve, ok let's start from the beginning...

For the map, you declare the width, the height and the map array

Code:

private height as integer
private width as integer
Map() as byte

The map array is now dynamic so that you can change the size of it anytime:

Code:

height=30
width=30
redim map(width,height)

To store this array you open the file in binary

Code:

Open Filename for Binary as #
Put#1,,width
Put#1,,height
Put#1,,map
Close 1

And to read it again you use Get isntead of put

Code:

Open Filename for Binary as #
Get#1,,width
Get#1,,height
Redim map(width,height)
Get#1,,map
Close 1
