Error in adoStream.Read()

[jennisy]

Hi, all,

There is a problem that during download file, if the file size is greater than 800kb, 500 error popup. But it is OK, if the file is less than 800kb.

Can anyone give me a advice? Thanks in advance.

The asp runs on II6, windows 2003 and AspBufferingLimit in windows\system32\inetsrv\metabase.xml has been updated to 20480000.

Here's the asp script:

if request.querystring("loadType") = "FILE" then
        'Upload.SendBinary resultFilePath,True,rs("PMEVR_TYPE"),False
            'Response.ContentType = "application/x-unknown" ' arbitrary
            Response.ContentType = "application/pdf" ' arbitrary
            'Response.AddHeader "Content-Disposition", "attachment; filename="  & rs("PMEVR_PM_FILPTR")    
            Set adoStream = CreateObject("ADODB.Stream") 
        adoStream.Open() 
        adoStream.Type = 1 
        adoStream.LoadFromFile(resultFilePath) 
        Response.BinaryWrite adoStream.Read() 
        adoStream.Close 
        Set adoStream = Nothing 
        Response.End 
end if
 

regards,
JY

you could try turning the response buffer off completely, not sure if that will help or not. Try linking to the file directly in a static page, if you have the same issue then the problem is in IIS, if not then it is an ASP issue.
