Response.BinaryWrite not working.

i am trying to output an image using response.binarywrite.
the following is teh code i am using:

Dim objStream
  Set objStream = Server.CreateObject("ADODB.Stream")
  'Open a GIF file
  objStream.Type = adTypeBinary
  objStream.LoadFromFile "C:\Image.png"
  'Output the contents of the stream object
  Response.ContentType = "image/png"
  Response.BinaryWrite objStream.Read
  'Clean up....
  Set objStream = Nothing

instead of outputting an image, it just outputs a string of byte (i think) data. eg. ‰PNG  IHDRg&™Ôº IDATxœì½\÷ÿO¿µßÚ«í¥={1­ÉÙœ—šži½×r—œ1­Müzš#Õ¼r•Zs¡§gMj¯ä§•‡Õ”$Ö˜„FkÕ« *âWAþ‰ŠBåËÿ™ß볟evvfvvfv—¿ï烇îÎÎοù¼>ïÏçý'D ‚ B!ƒ}A1l Õ$‚ ½0Õ´ÙzbcKð·eK^k¬m·÷ΟŸ[Yi¨#”c±Ôð£µZ¯ä~.b§ë֝Îξ®½f\\iTTö¶m•s`横jÃ¥¦ÖI64ta¡t VÀÎ?Z¶,W€¿ññŸà4qÏ8÷Äõ naM¼

does anyone know what is happening??

Try Response.ContentType = "application/octet-stream" or Response.ContentType = "image/gif".

in order to use response.binarywrite, I believe you first need to use the request.binaryread method to retrieve your binary data.

also, do you have the adovbs.inc included?  If not, you'll need to assing a value to your adTypeBinary constant, as they are not inherently available to vbscript applications (forgive me if you already know this)...

adTypeBinary = 1, by the way...

Also, try a Response.Clear right before the call to BinaryWrite.

magic.... :)

okay, you don't believe in magic?

the response.binarywrite method is a bit fragile and thus requires gentle treatment... :)

Allowing the script to generate additional textual output (through Response.Write or directly) may corrupt the data sent. For example -- trailing bytes appended to an image streamed binary. It is typically a good idea to use response.end at the end of the script and response.clear at the beginning in order to avoid any output.

anyways, glad to help.
