Did you unregister the previous DLL and register the new one?

Hi Pallini,
Thank you for responding.
Yes, in fact I can unregister the old DLL, register the new DLL, try the test code and it will fail. I can then unregister the new DLL and register the old DLL and it will work fine.
Other ideas?

Have you done, using the debugger, a constistency check between clsid and __uuidof(_WebRes) ?

Actually this picture shows that there is consistency.
Can you get an instance of the object via, for instance, OleView tool?

Hey, wait a moment. The code snippet of tlh file you provided in your OP is relative to the old DLL. I hope you aren't using it.

C.Palinni, you are a genius!!! That was the issue!
You know, at some point I had thought of that but obviously screwed it up. You would think that after the multitude of compiles I've done, registers and unregisters that at some point I would have lucked on the right combination.
Thank you so much for your help, it is very much appreaciated,
Best Regards
Phil

I can not refresh the forms of my application when I execute the .exe file. Whether I click over my application then the screen seens to be frozen...same result if I do soemthing with another application like web browser...I've tried with refresh() and bringtofront() methods but it doesn't work.
I would really apreciate if someone could tell me how to keep the forms updated when it is running...
c u soon...

How did you initially populate them?

Hi,
Thanks a lot for your help...
My issue is the following...when I'm running the .exe file... any further action I do with the mouse, lets say open another application or even click over my application cause that the screen gets frozen...i've added refresh() and Bringtofront() methods but they only work whether I run the application from the Builder IDE...
tks in advance for your help...

Instead of what? Is your application doing something at that point?

Yeah,
The application is a cellular networks simulator; some simulations are really heavy computationally speaking that the system I think is unable to refresh the graphical interface...but the curious thing is that only the app's screen gets frozen because the simulation itself keeps working properly; I've verified it because once the overall simulation process finishes then the application screen returns.
I've viewed some articles refering to threads but I have no idea how to use them...maybe there is another way !!

Put these computations into a worker thread.

well,
could you give me please additional insight how to do that...i've never use such threads so a tutorial or maybe a sample file could be useful...

tks a lot for your help...I'm gonna go over that inmediately...

maybe your frequent refresh leads to the frosen, try to create a thread to refresh

hi,
do ou have a sample code showing how to do that...
I've never used threads and I found it a bit complicated...
well, tks a lot for your help...

Multithreading Tutorial[^]
you can download the code here，although it isn't in c++ builder. It is written by api, hope it helpful.
anyway, i think the code in msdn is also valuable.

Hi,
I dont know whether there are some issues implementing threads by means of MFC in Borland C++ Builder.
I have found some problems with CWinThread class in Builder... have you some additional comments regarding it ?
tks a lot for your help...

MFC is a part of Visual C++, not for C++ builder, maybe the idea is useful.
If you do not want to use api or read codes in visual c++, please use TThread in c++ builder. there is an example contained in c++ builder
D:\Program Files\Borland\CBuilder6\Examples\Apps\Threads
you can file->new->others->thread object to create a new thread, See more in help file of TThread
