I have not declaired any data sources, like a data grid view or the text boxes from which my information is typed by the user (text boxes).
I have a problem with my code. My code is using the fileupload control to browse for a filename when you add a filename it processes it and the code runs fine on when it lives on local host, but when I put the code on our prodution server it cannot find the filenames listed by user.
For example if I use the upload control to browse to B:MISCH IntiveRPTTOFL_3.csv and the code lives on my localhost which know what that file path means it works, but if the code is moved to a production server it may or maynot know what B:/ is or B:/ maybe mapped to something else. Even if I am browsing to a file on my C drive it will work on if the code is on the machine that the C drive is on, but it will not work if the code is on another machine because obviously that file wouldnt be on that C drive.

I've worked out how to display charts in VB 2010 Express, but now I'm needing the user to input data into a spreadsheet/table that will be used within the program. I know that table is no longer available and neither is the OWC11 set. Is my remaining option then to use DataGridView? I know it is SQL based and I don't have much experience there yet, but I didn't want to commit to it if there is another method that would work just as well. The values that are put in by the user does not need to be preserved.
