FileIOPermission failed

[hemants]

I Have made an exe i.e Windows Control Library in vb.net

it is image editor which have embedded image as in Buid action property to Embedded recources.

That exe i m calling in Web page . it is executing Properly but

in Exe I am renaming the requested image with the earlier set embedded image and taking the backup of the embedded image. I do this activity by giving the absolute path of the image.

Now the issue is, when I run the EXE it works properly but when it is called thru a web page its giving an exception saying,

"System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

Please suggest solution to this problem.

Regards,
Hemant S.

Check what user the website is running as. In IIS, check the Directory Security tab for that website, and it should be under a button somewhere in there.

Make sure that that user has sufficient access to the file/folder by checking the permissions.
