Folks,

I am trying to use Delphi's ActiveX control wizard to wrap up a custom
component as an ActiveX control. This is something I have done many times
before without any problems.

However now when I try to wrap up my control I get the error message 'Cannot
load unit XXX symbol information for TMyClass. Do you want to try to find
this file yourself'. When i point the wizard at the .dcu containing TMyClass
I am just asked the same question again.

Does anyone know why this might be happening and what I can do to remedy the
situation?

Thanks in advance

(p.s. I have reproduced this in both D6 & D7)

Brian,

Thanks for your answer.

I already had the unit containing TMyClass added explicitly to an installed
'.dpk' but still experienced the problems. I found that I had to add
references to other units (used by TMyClass) to the search path for my
ActiveX library project & that fixed it.

Thanks again

Hi,

This is because the directory containing this project is not included in the
Environment Options-Library-Library Path. Including this in the path should
solve the problem.

Alternative method is to provide the required DCU file. You are probably
having some more DCUs which are required to create the ActiveX, for example,
MySomeOtherClass.dcu which is a helper class for MyClass.dcu. You have to
give this when it asks for the DCU.

Good Luck,
