Hi,
- I am trying to execute a GUI dll from my program (.exe)
- I have do all about exporting function that will be called from outside like this
In Dll :
extern "C" __declspec(dllexport) void ExecuteDll(bool A_bDecryptCcs);
What i need is to make a program (.exe) to execute this dll and it will be invisible because i need it to be like a Trigger just call and leave and let the dll working i.e the GUI of the dll still for me.
I hope that i explained my problem clearly and i hope so that someone have a solution and help me.
Thank you

- It is the DLL which should do all work
- the EXE should call the DLL which is a graphic interface
- the EXE call an exported function from the DLL only
- when i exit from the DLL all work is finished.
i hope that i explained more my situation.

And what stops you from implementing this? You don't know how to load a DLL, or you don't know how to call the exported method? As far as i can tell from what you said here, all your exe should do is load the DLL, call the exported method which i assume will create a window and run a message loop and after this method finishes, exit. Right?

I recapitulate all problem with:
i will have two files :
- EXE : just lunch the DLL and disappear
- DLL : called with its exported function (it is done) and it has the style of window and will do all work
and when i quit this window(exit from DD) is weening that my all application exit
the problem is when i lunch the EXE file, my window(the DLL) appears and disappears quickly and i need it to stay until i exit from it when i like!
So how can i do this ?
can i use a console application which lunch the DLL and still waiting? or there is an other solution

When your exe runs, what does it do, show some code (relevand code only). Also, what does your DLL do (also show some relevant code).

The EXE is just to lunch the DLL , that is all 
The dll is a MFC SDI application contains a main window that do all work.
And to lunch this DLL i need this EXE.
So if there is a solution to this situation please help.

Ok, i understand that, but without knowing some details about what you tried to do i can only guess...
So what i would first try is to simple load the DLL ( LoadLibrary ), and have an exported method -as i mentioned earlier- that brings up the windows and runs the message loop, localize this method (GetProcAddress), call it and let it run until it is done (the user dismisses the window, selects Exit from its menu, whatever...), and then exit. The EXE would sit in memory while the DLL's function is executed but i personally wouldn't care much. For the EXE i'd probably create a DIALOG BASED app in VS, remove the dialog and everything else that gets generated automatically by the app wizard, and in the applications's InitInstance i'd do the loading and executing and then return FALSE from it to exit. Or you could create a barebone project and do about the same just without any app class and the rest...it's up to you.

It's a simple problem. He wants to launch an application (exe). The application then calls a function in a dll (e.g. ShowMyWindow()) and immediately terminates. But he wants the dll function to continue to run.
Absolutely impossible, and totally stupid.

I read your posts but i am not absolutely convinced that he wants the exe to literally terminate, he just doesn't want to see it is there, not sure but i think he doesn't mean by that that the exe shouldn't be listed in task manager for example, he just doesn't want to see it on his desktop. But of course i might be wrong, if he really wants the exe to terminate that is indeed problematic...he could try to inject the dll into -i don't know- explorer.exe, start a thread and let it run there, but there has to be a better solution...

I agree the description is not overly clear.

Yes, he could study windows programming and learn what a dll is for.

This sounds back to front to me, assuming I understand the question. The exe file is the application that should be doing most of the work, while the dll portion supplies extra functions that are called on request. In any case you cannot leave a dll function running after the caller (exe) terminates. You may need to review your design.

As I said in my previous reply, you are doing this the wrong way round. The main work of any application is done in the exe file not the dll. You cannot leave a dll running after the exe terminates; it makes no sense to do things this way.

Not possible, otherwise DLLs could just start by themselves.

Remember that on Vista/Win7 then services are running in their own session. When starting the UI application then it must be running in the user-session.
Have feeling that it is better that it is user that starts the UI application (Maybe as a process started at user-login). The UI can then contact the service through whatever communication form you like. Namedpipes might be a good way.

How does the worker thread fills the list (I hope it just sends meesages and leave the UI updating task to the UI thread...)?

No surprise there. The worker thread should not be interacting with any UI control that it does not own. It should use PostMessage() instead.
