You might try using something like this: int WM_DLL_A_REFRESH = RegisterWindowsMessage("DLL_A:Refresh"); Software Zen: delete this; Fold With Us![^]

The RegisterWindowMessage Function (Windows)[^] defines a new window message that is guaranteed to be unique throughout the system, and is designed to generate at runtime message IDs that could be used for inter-process communications: using it solve your problem, but it could not be a good idea if you use it extensively, because it waste system resources. Anyway, the changement you are evaluating, requires that you manually modify the resource.h file on your project to remove the correspondant #define and produce a situation where the resource editor is not able to load and handle your resource script file (i.e. project_name.rc), then you should modify it manually.

You can declare the other cat function as protected. In that case, the dog can not access to that function

#ifndef, #define and #endif combination works to prevent redundant inclusion in the same file. This will not work if you are including them in different .cpp files. Since in that .cpp file the macro that you are checking is not defined. Hence it creates another std::string version var. What you have to do is create a global variable by declaring it in a header file which will be included everywhere (for example stdafx.h in VC6) like wise extern std::string version; and then defining it in any one and only one of the **.cpp** files. Now you can use the variable by including the header file where you wish to use the variable. Do read the faqs[^] too. Nibu thomas Software Developer

That's exactly solve my problem, thanks! :)

never mind, I got stupid. I shouldn't post in the morning. :) Tim Smith I'm going to patent thought. I have yet to see any prior art. -- modified at 9:59 Friday 23rd September, 2005

marshall interfaces seems not easy :( i think i will go directly for multithread apartment to avoid using marshall interfaces. since providing a synchronized protection on my activex control object much easier. :) thanks for help. this solve my doubt.

Thanks. Using COleDispatchDriver as parent class really work! I didn't use AttachDispatch since I cann't make it works. Most probably I miss out something. However, by using CreateDispatch just rock :) I assume there is no clean up needed after CreateDispatch from the MSDN example. Thanks for help! cheok
