Thread: Proccessing Large Text Files, Please Help

  1. #1


    My problem is that I have a text file thats around 6MB and its going to be getting bigger everyday, its a log file for a web server. I've tried to load it into a vb using the standard Open then line input stuff but vb either runs out of mem or hangs forever. If anyone knows code that will make it load a lot faster please post it or send me and email, Something like wordpad would work great, because it loads the file in like 5 seconds, any help would be appreciated, thanks.

    Why don't you use the RichTextBox control? It can hold up to 2 GB.

    RichTextBox1.LoadFile "C:\myfile.txt", rtfRTF 'or rtfText for regular text files

    RichTextBox1.SaveFile "C:\myfile.txt", rtfRTF 'or rtfText for regular text files

    ..just a suggestion .

    I think you can open the file binary... then get it in chunks and then calculate the loaded part and the filesize to show the progress.
    Use the RichTextBox as Matthew said, but open the file for binary.

    Alcohol doesn't solve any problems, but then again, neither does milk.
