Hi,

To check wether if the error is not on you part why dont you try the source code that comes with the book, that way you are easily going to know if the fault is within your code/project or permissions issue.

For me the code in the book was working.

In addition to what 07Raghav is saying, you may also want to debug your code (see chapter 18) and see what data the FileUpload contains. Are you sure it contains a valid uploaded file? And does the file have an extension? Also, are you using the code from the book as-is or is this your own code? Are you maybe using an UpdatePanel around your FileUpload?

Thank you 07Raghav and Imar

the problem is made by UpdatePanle , i removed it and now its ok but i don't want to post entire page to server just for inserting or updating , what can i do ?

Ah, that explains it. FileUploads inside an UpdatePanel are known to cause issues. Take a look here: http://stackoverflow.com/questions/3...the-whole-page or search Google for FileUpload UpdatePanel.

Cheers,
