Hi All,

I have a situtation my application is running on windows 2003 server which is a domain and in web.config

<Identity impersonation=true username=ABC\XYZ password=******>

what i am doing in the code that i take folder path from user and retrive all file information from that folder and writing to a CSV file which i am creating

using StreamWriter.

Dim objSW As StreamWriter = New StreamWriter("MMLIVFILTRE_080721_165835.CSV")

Problem is when user enter path like : 'C:\Foldername' then it is working fine and writing all the files informatin in to the file which is created by streamwriter.

but when user enter path : '\\servername\c$\foldername' then is is giving me the below error

Exception: System.IO.IOException: The process cannot access the file 'D:\MMLIVFILTRE_080721_165835.CSV' because it is being used by another process.

 'MMLIVFILTRE_080721_165835.CSV' in this file i am writing the information which is created by streamwiter.

can u tell me why this error is occuring. please tell me wher i am doing wrong ?

Thanks

Well if it says it is in use by another user then it is probably in use by another user.

Are you sure you are issuing objSW.Close() after you have finished writing to the file?

Hi Sam,

Thanks for your quick reply, yes i am closing and desposing the object.

objSW.Close()
objSW.Dispose()
objSW = Nothing

And what about processes that might read from the file? Or virus scanning software? Or any other number of things that might try to open the file... for reading or writing?
