Hi there.

My program is that the need of several csv files to make one csv and add something there. The user clicks load all csv files, which are then exported to a final. (attach program in the Annex, I do it in Visual Basic.Net and the Visual Studio 2012 Express)

Problem: in csv to give together, I have not a column ID, which resulting in need. Each csv file but a different ID. So if the first csv file has 10 records, I need to have all the same ID as you choose, for example. 124. Loading the next csv, for example 25 records and have ID again what I choose (546). I need it so that I knew that the record of the csv.

I hope someone will be able to help.
