I'm trying to pull images from our server but they are written on-the-fly with no extension (like a .jpg or .gif) for instance.

 Even if I set the content type like this:

    myReq.ContentType = "image/jpg"

 ...It still fails.

IF I set the content type I get this error:

System.NullReferenceException: Object reference not set to an instance of an object.

If I do not set the content type I get this error:

System.IO.DirectoryNotFoundException: Could not find a part of the path 'd:\imagedirectorytosavein\'.
System.IO.DirectoryNotFoundException:
   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

...But Regardless I always get an error. If I use an image that has a .jpg or .gif after it....no problem.

Thanks for your help.

please post the code that causes the error.

Thanks! Here you go...

            Dim b As Byte()
            Dim myReq As HttpWebRequest = Nothing
            Dim myResp As HttpWebResponse
            Dim ExceptionExists As Integer = 0
            Try

                myReq.ContentType = "image/jpg" ' Sometimes I add this and sometimes I don't


                myReq = CType(WebRequest.Create(url), HttpWebRequest) ' THIS SEEMS TO BE THE LINE THAT KILLS IT
              

                myResp = CType(myReq.GetResponse(), HttpWebResponse)
            Catch ex As WebException 
       
                ExceptionExists = 1

            
            End Try

 

in your example, you're setting the ContentType property of myReq before you have actually created the HttpWebRequest instance, so myReq would be null and that would seem to be the cause of the null reference exception

Yep, that was it. Thanks for the help.
