Any VB.net Experts Here? Help Needed

[radderfire]

Hi Guys

I have an old script written in VB.net that has a DataGrid that allows me to do simple editing of a MySQL database. This script used to work perfectly, but now it's stopped working. The error occurs when I hit the Edit button in the DataGrid. I haven't changed the script, so I think it's the hosting environment that is causing the error.

The full error is given below. The server is looking for temporary ASP.net files, but then failing to find them. It's running on a shared hosting environment.

Are there any VB.net experts here that can help me to rectify this?

Thanks

It's spitting out a DirectoryNotFoundException... have you checked that the full path it's looking for exists on the host server?

I would have to ask my hosts to. Are you saying they just need to browse to the relevant folder and delete the temp files?

I think when I then revisit the page, any temp files needed would be regenerated, is that correct?

Thanks

Actually, thinking about this, the error is saying it can't find temporary files. Therefore, it's looking for temporary files that it shouldn't be. So, I guess the vb.net application needs to be reset somehow, so it's not looking for temporary files?

How would the host do this?

Thanks for any help.

Anyone?

Have the host upgraded the version of ASP.net (or removed that version ?)

This... is .Net v2 installed on the server?

Is the app pool configured to use .Net v2? (Though I think if it's set to v4, .Net v2 applications might still run).

It's shared hosting, and I have a HELM control panel. I can choose either ASP.net v2 or v4 through the control panel.

I do think this is somehow related to the version of ASP.net. I am trying to find some suggestions for the hosting support team to resolve this, as so far they haven't managed to.

Any help is much appreciated.
