My friend need to do a application that able to read from a file to get some parameters for the application to run. The application will then generate some data into another text file (storing informations). The application should have limitation of the numbers of line for the content of the text files that can stored. Lets say the application will only stored 500 line for each text file, if the content of the text file reach 500 lines, it should automatically open another text file to write the content. When the program read back from the text files, it should get all the text files' content.

Anyone have similar sampel program in VB? Thanks in advance.
