RE: HELP! file input/output

  • 19 years ago

    I need to read variables and their values from a file, and enable the user to change them in this big window, and of course save them back to a file. Seems pretty standard, but i don't know how to do it? Anyone help? Is there any code on the web i can copy/take a look at?


    Please email me back at t-tzetc@microsoft.com
    thanks

    Big window?  I think you need to be slightly more specific.  But hopefully this helps a bit:


    iFile = FreeFile
    Open sFile For Input As #iFile
    x=0
    Do until EOF(iFile)
      Line Input #iFile, sData(x)
      x = x +1
    Loop
    Close #iFile


    Now you have the data in an array.  You can display it however you like to in the big window, and when you want to rewrite the data, you do this:


    iFile = FreeFile
    Open sFile For Output As #iFile
    x=0
    Do Until x = UBound(sData)
      Print #iFile, sData(x)
      x = x + 1
    Loop
    Close #iFile


    Any more questions, click the Visual Basic Button at the top and then go to Tutorials and Tips, then File & Directory perhaps.  Good Luck-
