visual basic

Hi all;

I know this is not a Visual basic board but i figured there has to be someone here who can help me out. My problem is when i read through a text file i need to extract only the numeric data from the file. The real problem is that this needs to be done in visual basic, and i do not know where to start. I have opened up the file and read in its contents line by line

Do Until EOF(1)
Input #1, strIn
Loop

but i do not know how to validate the strIn string for numeric data.

Thanks for you time.

Noones gonna help you here b/c this site isnt for basic or visual basic so go somewhere else! Try the general programming forum at www.gamedev.net i know there are a lot of VB programmers there.

I'm with xds4lx on this one. Visual Basic is evil and must be eradicated from the face of the earth.

And as to your actual problem, try reading it to a string variable then use the Val function. It'll atleast be a number that way.

Try asking on the forums at www.programmersheaven.com

Try this ( I'm probably going to get shot for answering this... sorry guys/gals :( ):

Anyone offended by the site of VB code should cover their eyes before reading further.... :confused:

Code:

---

dim iFF as integer, iStrLen as integer, iMidCntr as integer
dim iLineLen as integer
dim sFileName as string, sLineIn as string, sMid as string
dim bNumFnd as boolean

bNumFnd = false
iFF = Freefile
sFileName="C:\test.txt"
open sFileName for input as #iFF
 do while not eof(iFF)
  line input #iFF, sLineIn
  iLineLen=len(sLineIn)
  for iMidCntr = 1 to iLineLen
    if IsNumeric(mid$(sLineIn,iMidCntr,1)) then
      bNumFnd = true //this would be where you do your extraction
    end if
    if bNumFnd then bNumFnd=false //reset it before reading in the next bit of data
  next iMidCntr
 loop
close #iFF

Since I'll probably be banned for answering this...:( for future VB questions go to the VB Explorer Forums at http://pub13.ezboard.com/bvisualbasicexplorer or their main page at www.vbexplorer.com .

Oh, man, I just realized I used hungarian notation in my example..

Help when you can man. I also use VB from time to time, the only reason I didn't try to help other than post a link was that I was busy, and I don't have VB in the office, (one has certain standards you know!).

Why? VB isn't the best language, but that doesn't mean it should never be used. As adrianxw said, help out whenever you can.

>Oh, man, I just realized I used hungarian notation in my example..
This might get you shot, hungarian notation is the devil's spawn. :D

Why is hungrain notation bad again?

I was just joking. I mentioned DavidP because I know he has a comment about hungarian notation in his signature.

I was half-joking here. I make my living in VB (well most of it, probably about 70 (VB) - 30 (C++) ).

A lot of VB programmers have the idea that they are considered "lesser" developer (happens to be a popular topic on VB forums) by C/C++ programmers. I don't believe it. I think VB has it's strengths (especially for rapid DB development) and I made it clear when I first started posting here that I was coming from a VB background and everyone was really helpful and friendly.

I think that's because VB is so easy to use, C/C++ programmers like to torture themselves, it makes them feel better about themselves i guess.

Thank you so much jdinger. Your help was very usful to me. thank you again.
