I have a txt file and there is 50 lines and in each line has 50 ascii marks.
How i can read ascii marks on area that is lines 20-30 and rows 10-15?
Hope you get what i mean.

Hmm... you can't with QB but I do know how you can. If you know maps with rpgs darkdread style then this will be very easy for you. Follow the steps and there you go.
1. In between every character, put a comma (I don't know any faster way, sorry)
2. DIMension the array (1 TO 50, 1 TO 50)
3. Load the file into the array the same way you would a map.
Code: Select all
FOR y = 1 to 50
FOR x = 1 to 50
INPUT Array(X, Y)
NEXT
NEXT
Now your file is in the computers ram.
4. Read it the same way you would a map.
Code: Select all
FOR Y = 20 TO 30
FOR X = 10 TO 15
Array(X, Y) = ....
NEXT
NEXT
That will give you the charectars you want. I would reccoment putting them in a new array if you are using them more than once. Otherwise, this will do if you are doing something really simple (like printing it to a screen)

Sure you can with QB. If it's an ASCII file, all you need to know how to do is:
1. Keep track of line numbers (hint: use variables)
2. Know how to use MID$
3. Know how to use LINE INPUT
4. Knowledge of fixed-length strings might help if all the lines are of the same size, otherwise, just knowing how to work with strings is all you need
It's quite elementary, really.

I hate you... grrr... hey, it was early. I like to take the long ways sometimes, anyway. It's also fun to confuse noobies sometimes.

I have no idea what the relevance to that could possibly be.
