Hi, I have got the the following error when i'm trying to upload an excel file and store data into SQL SERVER.

The Microsoft Access database engine cannot open or write to the file ''. It is already opened exclusively by another user, or you need permission to view and write its data.

when i run on Visual Studio everything works without any errors. Once i deploy up to IIS 7 this error came out. But I can login using the userID and password stored in the database. What should I do to resolve this error? Thanks!
' Read the file and convert it to Byte Array
       Dim filePath As String = FileUpload1.PostedFile.FileName
       Dim filename As String = Path.GetFileName(filePath)
       Dim ext As String = Path.GetExtension(filename)
       Dim contenttype As String = String.Empty

       'Set the contenttype based on File Extension
       Select Case ext
           Case ".xls"
               contenttype = "application/"
               Exit Select

I forgot to add on actually when i run on Visual Studio everything works without any errors. Once i deploy up to IIS 7 this error came out. Something weird is i could login using the userID and password stored in the database.
