Passing a String from the URL

OverviewHow Do I

The next step in the example demonstrates invoking the command RegisterUser on the server MOOSE. The command RegisterUser is the name of a member function in the server DLL SURVEY.DLL. The client invokes RegisterUser from the following URL:

http://moose/survey/survey.dll?RegisterUser?Richard

This URL causes the member function RegisterUser to be called with pstrParameter pointing at the string “Richard”.

If Richard wanted to register his middle initial and last name too, the URL would look like this:

http://moose/survey/survey.dll?RegisterUser?Richard+M%2E+Jones

The string contains multiple words and punctuation, so the server expands the normal plus sign and percent sign URL character escapes before passing the string to the parse map. The character escapes are automatically filled into the URL by the browser and are not specific to ISAPI. For more information about the URL character escapes, see the Web site:
