Cetin,
I am honored that you would ask me a question. However, I have not tried to put a .Net control on a VFP form. I have succeeded in creating a .Net form, populating it with a checkbox,combobox, and button. I also have been able to use clrbindevents to hook into the click event of the button.
There are obviously many holes in this system that need to be filled before it can be taken seriously for production work. One of the chief of these to me is documentation. I have contributed my $120.00 and I hope enough of our community does the same so that this work can go forward.
A problem is a problem only as long as it has a possible solution. Lacking that, it becomes a FACT!
