Well, it don't really get what you're saying, but to make a string a null value, just do this:


Hope that helps,

You could try printing a bitmap picture of the screen over the text, but basically you have made this program in the wrong way. You should be using sprites, or plains for text.

Why delete the strings anyway? Thats just ineffective. Instead try and reuse them. You talked about a PowerPoint like thing. So why not do so everytime you proceed, the strings change. Then you wont need an extrem amount of them, just use them again and again with different "contence".

Agreed!

Use just one string over and over again - don't create a string for each picture.

If you absolutely must have multiple strings, use a string array. You can then use UnDim to delete them - if you need to.

If you aren't sure about arrays, they are covered in the tutorials on my web site (link at bottom of my post).

Radius you're not going to get anywhere in programming if you give up that easily right when something hard comes along. Even if the assignment has passed you should still finish it so you dont run into the same problem again.

I think he was structuring his program completely the wrong way. You can post the code you had and we'll explain what to change
