Hi PPL

I have a problem with referencing.

I have one MDI Form that creates and instance of my DLL(Name = cTrans) and loads it full of collections. I need to pass the this reference to other DLLs that I open from my MDI form but the problem is that I have one ActiveX DLL Project that does not open directly from my MDi form, it first passes through about 5 DLLs(maybe more) before my DLL is actually opened.

I need to pass this DLL a reference of my cTrans DLL. Can I use a call back or is there any way for me to pass the reference of this DLL to the other DLL with having to pass the reference through those other 5 projects?

Hi Deshin,

First, I would advise that you examine the structure of your application. COM applications are supposed to be as self-contained as possible, and it looks like the links between your DLLS/APPs are over-complicated.

There is no way of setting a reference to a DLL that is 5 levels deep without using EVENTs, Call-backs (which are just glorified events, anyway in vb), or passing the parameters through all 5 levels, or passing the DLL back to your main application (again, through all 5 levels).

My recommendation would be to restructure the dependencies of your projects that cause these 5 levels, or move the classes of the problematic DLL into an existing DLL.
