File with fields of 1 byte binary len followed by "len" bytes of displayable data

2 posts in this topic

I am drawing a blank as to how to process the subject file in AutoIt.

I know how to do it in C but I don't have a compiler available right now.

I have a file that is made up of variable length elements that have a single byte binary length followed by that length of displayable characters.

For example: 0x053132333435024142 which should yield "12345" and "AB"

I need to "walk the file" extracting all of the individual displayable data.

Any one have an example of how to do this?

I am getting all wound up with reading the file in binary, BinaryToString .....

Read the whole file with FileOpen() in binary mode, and then use BinaryMid(), see help file.

Even better open the file in binary mode, the FileRead() in a loop getting one byte, then $iLen bytes, then one byte, etc.
