reading negative numbers from a file in VB

[complete]

So far the code I have written can read and write to and from a file.

In other words, I have the

    Line Input  #FileNum...

and the

     Write #FileNum...

written.

But how do I handel a situation where the file has negative numbers to be read? I am able to output to a file a negative integer. But when I try to read it back I get an error.
I assume I will have to read each line of the file one by one into a string and then have it converted. What are the string conversion routines in VB? The line of code is written as

-1

I suppose I have to do some string manipulation to get it stored back as a negative integer.

Replace Delphi with your programming language of choice (minus PIC C)

Although we can try to help.

I don't know VB worth crap, so there could be an easier way, but I'd say that you could check if it begins with a '-,' strip it off if it does, convert the main part to a number, then multiply by -1.

IE, if you have "-5" in a file, you take off hte negative ("5"), convert it to a number (5), then multiply by -1 (-5).

If you're using the Write # statement, you should use Input #, not Line Input #.

Otherwise, VB is very good about preserving data.

I believe the string conversion routine you're looking for is:

val()

It'll convert a string to a number.

The opposite is:

str()

(which converts a number to a string).
