Uploading/Downloading folders with a .NET control built in VS2010

RE: Troubleshooting uploading/downloading folders in VS2010 .NET via an embedded web page control

I have a .NET control that I've embedded into a webpage. Simple enough; however when I deployed an instance of the FolderBrowserDialog class, access to the local file system throws the ever fun File.IO permission error when a local folder is chosen with the dialog.

I've tried building a .net/ActiveX control as well as a .NET project to address with this with the various assembly changes that are posted in this forum to no avail.

Anyone come across a working version of such a control? Alternatively anyone know what the proper permission sets are in order to get this to work?

Thanks much in advance

Does anyone has any suggestions here?

For those that have responded and to avoid answering this in the future, the server is not ASP and is in no way related to the functionality/component issue that's causing the problem.

Thank you for the response; however that doesn't address the point. The folder the app needs to upload contains hundreds of small files and sub-folders which means that it will have to access existing folders.

Any idea of what the assembly / linker changes need to be in order to permit fileIO operations from within a control embedded control in a web page?

HI,
Permission related errors are normally throwing when ever you selecting a folder programetically. Just try this. Create you own folder and try to select it. You may not get any errors.
