13.2 Create aSimple XML Web Service Using Parameters
I have seen how to create aWeb Service using the sample that Microsoft provides. This
was ... Login Name and Password. It
will then check against a table that you will create of names, passwords, and security
levels.
The method you will create first will then pass back True or False ... create aWeb Service that uses parameters?
Technique
For this How-To, you are going to create the start of a security Web Service. This
security Web Service is going to take in two parameters:...
