All,
I got a new workstation. I installed VS 2012 (same version as my old workstation v4.5). I copied the project to the new machine and opened it. I ran it (before compile) with seemingly no issues. So, I compiled it. I tried to open it on the same machine and I received the following unhandled exception error...
InvalidArgument=Value of '0' is not valid for 'SelectedIndex'
I have attached the entire unhandled exception error that I am getting on the new machine, as well as the problem code. This did not happen on my old workstation. So, I went to see if there were any version differences between my old workstation and the new one and low and behold Microsoft updated .net from 4.5.1 to 4.5.2.
What I am trying to do is set every combo box to selected index of 0 when the form loads. The funny thing is that even after the unhandled error (which never happened in v4.5.1) all the combo boxes are set to index 0. So, the code works perfectly. Why? Is there a way to code around this problem in v4.5.2? Also, if I keep developing using 4.5.2 won't all my users have to update to .net 4.5.2 as well?
