I've downloaded your Trial Version and tried to solve the Tutorial in your PDF manual.
I'm able to link the TsiLang component in the main form with the dispatcher but i can't link the TsiLangLinked components on the MDI Child and the AboutBox. The LangDispatcher field is empty, i can't select the dispatcher like in the main forms component. The same problem is with the common container.
Is this a limitation of the trial version?
Just add a unit which holds dispatcher to uses clause of the unit from which you need to be able to link. The same applies for CommonContainer property.
This is the first time i'm working with c++ builder and I do not realy understand what you mean. (And my English is not the best) Can you give me more explanation?
Thx
Example:
1. Open your AboutBox form
2. Press ALT+F11
3. In appeared list select your main form's unit (where TsiLangDispatcher is placed) and click OK.
4. After that you will be able to pick dispatcher from drop-down list in Object Inspector.
Hope this helps.
