Response.AppendHeader problem

[manutektips]

Hi,
I have a problem with opening a gif image. The code is below:
MyFileStream = New FileStream
(strTreeFilePath,FileMode.Open)
FileSize = MyFileStream.Length
Dim Buffer(CInt(FileSize)) As Byte
MyFileStream.Read(Buffer, 0, CInt(FileSize))
Response.ContentType = "image/GIF"
Response.AppendHeader("content-disposition", _
"attachment; filename=" + strTreeFilePath)
Response.OutputStream.Write(Buffer, 0, FileSize)
Response.Flush()
MyFileStream.Close()
Response.Close()
My program is generating a gif file dynamically and stored in a folder. When I try to open that file using the above code, the page is loaded but not picking up the file. This same programs works fine in 1 server but not in another, where both the servers are windows 2003. Please help

Are you getting any exception or any error?
Did you check the permissions?

Sharing the best from my side...
