I used information found in the MSDN magazine article about HTTP Pipelines
in the September 2002 issue to convert code that I had running in the page
load event of an .aspx page to use HTTP Pipelines. First, I converted the
code to a DLL that implements the IHttpHandler interface, placed it in the
bin directory of my virtual directory, added the httphandler to the
Web.config, and added my new extension to the IIS metabase to map to the
aspnet_isapi.dll. This worked perfectly.
Then, the article goes on to explain that using an .ashx file, I could avoid
the deployment issues with changing the web.config and updating IIS. So, I
decided to convert my DLL to an .ashx file. I followed the article. When
I try to execute this page...one of the first lines in the codes uses the
LCase function...I get an error saying LCase is not defined. I comment this
line out...the next uses the IsNothing function...I also get an IsNothing
not defined error. I'm also referencing the System.Messaging dll in this
file. When I reference objects in this library, I get errors that they are
not defined. Are there tight limits on what one can and can't do in an
By the way...I'm using vb.net...not C# as the article does.
Thanks for your help...
