Hi ,

we got error when upload image file to database directly.

the error message is : "Message from webpage. Server site exception: failed to upload [my filename]. System.Data.Sqlclient.SqlException: Procedure 'WebXpress_AjaxUploader_Append' expects parameter '@Guid' which was not supplied at WebExpressManagement ....."

or

public override void Save(Guid guid, string filename, System.IO.Stream stream)

 

 

 

we created our own provider, the source code sample is from http://cutesoft.net/forums/thread/57229.aspx.

 

any help will be really appreciated!

 

Best Regards

 

Hi

the error is reported by our user, we cannot repeat the same error. checked the database found the most of upload files cut off at 65536 bytes and the Uploader_FileUploaded event have not been fired yet.

looked around the forum, we found one similar issue, http://cutesoft.net/forums/thread/47795.aspx.

 

so we changed the uploadtype from auto to flash, hope this help.

 

if you have any other better idea, please let me know.

 

thanks a lot. 

Hi,

 

When you use Silverlight mode, you need implement the AppendData method correctly.

 

Because Silverlight will split the file into small pieces , and call Save once, and then call AppendData many times.
