I like to use ocx to connect to a c++ dll but when I do I get Debug Assertion Failed in mfc120d.dll
in the tooltip.cpp.
So my question is can I use ocx in a hydra delphi vcl plugin?
you can use osx in hydra delphi vcl plugin
can you create a simple testcase that reproduces your problem?
A colleague has solved this issue. It had something to do with the installation of the ocx.
