You can open a class library even if included in exe and parse it:
SELECT 0
USE Myclass.vcx AGAIN
LOCATE FOR objname='myclass'
IF FOUND()
USE
This.cHtml=This.cHtml+This.RecordHook()
ENDIF
USE
>I have a class which contains a method called RecordHook(). When that class is instantiated, it may or not contains some code in the RecordHook() method. However, in the main class, I have this code:
>
>
>This.cHtml=This.cHtml+This.RecordHook()
>
>
>This code gets executed even if there is no code in RecordHook(). I would prefer to have the RecordHook() method, when it contains some code to have this as the last line of its code:
>
>
>RETURN lcHtml
>
>
>However, if there is no code, this will fail.

>I understand that I should do something like this if I want this to work all the time from the main code:

>This.RecordHook()
>* The HTML code is now appended to This.cHtml
>
>
>and from the RecordHook() method in its last line:
>
>
>This.cHtml=This.cHtml+lcHtml
>

>But, as I would prefer to have the RecordHook() method to return the HTML, would it there be a way to determine if some code is present in RecordHook() so I could have something like this:

>IF This.RecordHook.CodeIsPresent
> This.cHtml=This.cHtml+This.RecordHook()
