Hi all,
I ve been developing applications in VB for long time, I ve been depending on creating my own files using the available VB commands and manage the contents of these files in order to be abale to save and retreive the data.
Although, I'm completly satisfied with the results and the technique , I c itsn't commonly used by developers I know, who usually use MS Access or whatever . So I like to know ur opinions and what do u think about that and why u think so.?
Thanks
