TagsDBGetFirstClassMember

This function returns the name of the first member in a specified class. It acts like an array pointer, with the array being the class members, and it may be used in coordination with the function TagsDBGetNextClassMember either to generate a list of members in the class or to process the class members one at a time, depending on how you write your script.

Syntax

  TagsDBGetFirstClassMember( strClassName )
Web Studio Help b tagsdbgetfirstclassmember.xml d435967e116 TagsDBGetFirstClassMember
strClassName
The name of the class in which to get the first member.

Returned value

If this function is executed succesfully, then it returns the name of the first class member. Otherwise, it returns one of the following possible values:
Value Description
-5 No members found in the specified class.
-4 The specified class does not exist in the tags database.
-3 Wrong parameter type or inconsistent value.
-2 Invalid number of parameters.

Notes

This function can only be executed on the project server — it cannot be called by a Graphics Script, Screen Script, or Command animation running on a project client.

Also, this function may be called at any time; the function TagsDBBeginEdit does not need to have been executed previously. If that is the case, however, then TagsDBGetFirstClassMember and TagsDBGetNextClassMember can only generate a list of classes. They cannot be used, along with with the other Tags Database functions, to edit the classes.

For more information about the Tags Database functions and examples of how to use them, see Edit the tags database during run time.
