allow selection of files in asp.net
Posted on 2013-11-01
I am trying to write a asp.net app (using VB) that will perform 3 functions
1. allow a user to select a csv file
2. read the file and perform validations
3. log results of validations
I know how to do #2 and #3 no problem
If I were using a windows application I would use openfiledialog to accomplish #1. Apparently, openfiledialog is not available in asp.net
Any ideas on how to emulate the same functionality in asp.net
I just want the user to be able to select files ...I am not looking to save or upload files

I think you are missing a fundamental concept of how web applications work. The VB code you write runs on the server. If you want your VB code to be able to read through a file the only way to do that is to upload the file to the server so the VB code can get at it.
