To be able to seperate the different records you can create a function to parse the files that you read into your program. I have released a OCX Control on my web site which does this for you without any code. Here Goes 1. Start a new Standard-EXE project, form1 is created by default 2. Add a module to your project. Project, Add Module. The code window is displayed by default. Add the following code : 3.Open up form1's and add a command button. Open up the click even for the command button and type the following: Msgbox ParseString("Visit - www.microweird.demon.co.uk - for everything on Visual Basic", "-", 2) 4. Run the project (F5) and click on the command button and 'www.microweird.demon.co.uk' will be displayed in a message box. |
