The array insert at bottom is what is causing it. Whenever I try inserting something at the bottom, top, or at an element, the whole thing freezes up and crashes.

have you tried dimming the array this way:

Dim Array(0) as String

Instead of this:

Dim Array$(0)

other than that i don't see the problem.

Why would that change anything?

Your for-loop is running until array count(Array) is reached. DBPro evaluates the beginning and end statement for such loops in each iteration and thus you will get another run whenever you insert another element. That is probably not what causes your problem though, but it's worth thinking of.

Quote: "array delete element array$(),b
array insert at element array$(),b "

That is probably what causes problems. If b is the last element in the array and you remove it, then the index b is out of bounds when you later try to insert at that element.
By the way, why would you want to remove an element only to recreate it again? You can just overwrite the previous entries, you know

You're right... IDK why I didn't think of that lol.

But that's not the problem. Here is the code I am now using:



The "}" symbol needs to stay at the bottom of the array at all times. But whenever I try adding a new element to the array inside the for loop, the whole thing freezes up and crashes. How else could I do this?

Basically, in the end, it will check if the string already exists in the array, if so it will change the string and add a "v2" after it. If the string isn't already there it adds it to the second to last spot in the array, the last spot being "}".

If I take the insert element out of the for loop and put it just after it, it works fine, but then it adds a new slot whether or not the string already existed in the array.

EDIT: I kind of figured how to do it. I need to set a variable so that if it doesn't find the string, then it sets it to one. If that variable is set to one then it inserts the string to the bottom.

Since it's a for loop, it will always end up being one, because only one of the passes through the for loop won't set it to 0. I guess I'll just have to inc the variable, and if it is less than the array index then it doesn't add it to the bottom.

Am I on the right track?

My question is why add "Body {" and "}" to the array at all. If it's for just printing to the screen you can just print it before and after to give the illusion it's in the array. Same thing with saving to a file.

Because it will end up saving it to a CSS file. I figured it out though with the concept I posted above. Everything is working smoothly.

I'm glad it's working good.
