Hello,

We can guarantee the correct work of the AssignConnect method only if both library and project are compiled with the same version of UniDAC. Please check if the problem persists if you are using UniDAC 4.1.3 for both your library and project.

If there are not many changes in the TUniConnection component from one UniDAC version to another, the AssignConnect method can work correctly. But there are a lot of changes that we made between UniDAC 3.6 and 4.1. Please recompile your library and project with UniDAC 4.1.3. It will solve the problem with the AssignConnect method.
