Response.BinaryWrite

[Laurahn]

Hi:

I'm dealing with a file type when i convert it from a BLOB field on database and i use the Response.BinaryWrite method. The file type is *.chm. That's my code:

Private Sub ReadFile(ByVal MyData() as Byte)
If Not MyData Is System.DBNull.Value then
Response.Buffer = True
Response.ContentType ="application/octet-stream"
Response.BinaryWrite(MyData)
End If
End Sub
When i retrieve different type of file "Response.ContentType = "application/msword"" the code works fine. I can see the file on the IE or download the file to disk.

Can someone tell me, how can i retrieve *.chm files from database to end user. I want to make a simple download of the file.

See Rick Strahl's recommendations at :

Bottom line : don't try to stream chm files directly for client usage.
Always have them downloaded to the client and let the client open them later.

I got the answer:

Is needed to use a diferent parameter for download a *.chm file:

Response.AddHeader("Content-Disposition", "attachment;filename=MyFile.chm")

This KB describes a similar scenario like yours.

Please feel free to reply here if there's anything else I can help.
