(Why 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 - Simon Moscrop (p.s. I have reproduced this in both D6 & D7) Back to top Brian Cook Guest Posted: Wed Oct 22, 2003 4:03 pm    Post subject: Re: Cannot load unit XXX symbol information for TMyClass ??

If I remember correctly, unit "XXX" must be included in the project (listed in the DPK) file used to build the package. Referencing the unit from another unit isn't good enough. Good luck, Brian Back to top Simon Guest Posted: Thu Oct 23, 2003 9:18 am    Post subject: Re: Cannot load unit XXX symbol information for TMyClass ?? 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.

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, -- Sam. "Simon" <nospamSimonMoscrop (AT) Hotmail (DOT) com> wrote Quote: Brian, Thanks for your answer.
