Hi Anton

Thanks for your response. I had given up on this post :)

>1) You still can call procedures form other APP using "DO fwmain.prg IN myapp.app"

Ok

>2) You can istantiate objects of classes defined in external APP using either NEWOBJECT() or call to procedure which instantiate that object and returns pointer. I recomend the second approach because NEWOBJECT() fails to incorporate graphics and other files compiled to external APP.

Ok

>3) But you cannot subclass classes defined in external APP. Hovewer, you can use directory of shared class libraries. This is how I do.

Subclass is required by me at design time mostly. Now how can I hide as well as allow subclass at design time. In any case when the project is compiled it will start looking for the parent class libs. How can this be countered.

Please advise.
