I'm developing a software for an insurance broker. They have existing excel files and they required me to upload excel files into the software i'm developing. Is that possible? If so, can anyone guide me into this... Thanks in advance.
Indeed you can upload all the contents of an Excel workbook into a .NET application by using the Excel Object Model. I suggest you to look at the Chapter 10 "Automating Microsoft Office Applications" of the well known book "Mastering VB.NET".
There you'll find all the information you need. It was very useful for me too!
