Openfile problem

Is Openfile bugged? I need to open a file which has 7 strings in it. I need to ignore the first two strings, and replace the remaining five. My plan was to use openfile, use readline to read off the first two strings and put the pointer to the correct position, and then use writeline to replace the remaining 5. But the writeline command just seems to do nothing.

The only other way around it I can see it to open the file with readfile, read and store the 2 strings, close the file, open it again with writefile and then put all 7 strings back in and close it again. Seems like a very long-winded way around it.

Am I doing something wrong, or is openfile just bugged?

You can't use ReadLine() to read strings (unless they aren't actually strings, but lines :). Try ReadString() instead.

Also, strings (and lines) aren't a fixed length, so trying to replace them with WriteLine (or WriteString) will probably overwrite more (or less than) one line/string. You are better off creating a new file (or overwriting the old one) and copying the parts you still want and your new parts to it.

Confused?

PS. OpenFile() isn't bugged, but you should use ReadFile() if all you want to do is read it. OpenFile lets you read and write to a file (without closing it).

That's odd, I've been using Readline and Writeline to read and write strings to my files for ages, seems to work fine.

I guess in this case I will just replace the whole file, at least it works. :)

Generally, I don't use OpenFile, because ReadFile and WriteFile give me all the functionality I need. Are you using the FilePos and SeekFile commands in conjunction with OpenFile, to find your way around in the file? If not, then from what I understand from the Help docs on the command, your use of OpenFile is incorrect.



I hope this helps.
