Searching through a file

I'm getting a path (e.g. pics\temp.pcx) out of 1 line within a file (models\temp.md2).
However, the file is not pure text, so FileRead only gets to the second line and produces an error.
Is there a way to convert this file to pure text?

FileReadByte doesn't care if the input is text or not, so you can use it to process the file.

It's just outputting a load of numbers.
I need to get a line out of the file and search for ".pcx" in it

I just need to get hold of a line of text from it now...

Use:

IntFmt $0 "%c" $1

where $1 is the output of FileReadByte and you'll get the character read in $0. It's up to you to find out how to skip the non text part of the file, FileReadByte will read anything.

I shall look

[edit]heh, ok 🙂[/edit]

Then the byte read is a character that can not be displayed on screen, maybe 0. As I've said, it's up to you to tell where the text you want begins. Use FileReadByte to skip the parts you don't want, or can't read.

Ok, so I have tried to collect up 20 characters, and then search for .pcx in that:

loop_read:
ClearErrors
FileReadByte $R2 $R3
IfErrors error
IntFmt $R3 "%c" $R3
IntOp $R5 $R5 + 1
StrCpy $R4 $R4$R3
StrCmp $R5 20 0 loop_read

But $R4 comes out as only about 4 characters long.

What have I done wrong?

Ok, It's not outputting spaces. At least I am getting part of the ".pc" in it!

Here's what I made..

Works great on both md2 and sp2 files 🙂
