Hello Toto,
Yes, it's possible to create such a DLL. Since you posted in the ActiveX
newsgroup, I suspect that you want to create a COM object, right? If yes, it
sounds like you actually need three COM Objects:
- a 'business' object
- an 'order' object that's exposed by the 'business' object
- a 'Product' object that's exposed by the 'business' object
If that's what you're after can you confirm now these objects will be used?
Via automation? Remotely? In a proprietary application?
We need more information to be able to be of more help to you.
Regards,
Bruneau.

Bonjour,
la premiere langue que j'ai etudiee.
decrire l'usage des Wizards en Anglais:
1. File|New|Other|ActiveX|ActiveX Library
La vous allez creer le DLL qui contiendra les Objects COM
2. File|New|Other|ActiveX|COM Object
Et la vous allez creer un object COM.
Vous pouvez repeter la deuxieme etape pour creer tous les objects:
'business', 'order' et 'product'.
Ensuite, vous pourrez vous servir de l'editeur TypeLibrary pour ajouter une
propriete 'order' et une propriete 'product' a l'object 'business'. etc.
etc.
Laissez moi savoir si tout est clair!
Salutations,
Bruneau.

Dear all,
I need urgently help, since I am in trouble with my exam:
I am programing a velledom card which is connected by UBS to my computer. I
am using Borland C++ version 5.0. Basically in the User Guide everything is
described fine. Here is the user guide:
www.produktinfo.conrad.com/datenblaetter/175000-199999/191003-an-01-de-Programmieranleitung_K8055_DLL.pdf
I am using the code on the last page of this guide. I did it exactly how
it's described but by compiling the code I always get the following error:
[Linker Fehler] Unresolver external "OpenDevice" referenced from
C.\programme\borland\cbuilder5\projects\vellemann.obj.
I have the K8055D.dll in the same folder as the project.
Do I need to include something to the project?
Please help me I need some hint.
Thanks
 

You can make it using borlands tools .. find BIN library under Borland C++
Builder folder.
then use :
implib k8055d.lib k8055d.dll
to make k8055d.lib.
Add Library(lib) file to Your project and try to compile once again.

Dear Juris,
Thank you a lot. It works and you have saved my exam.
Thanks

What DLL's do I have to supply in my install.exe for my Datansnap
application? (Delphi 2006 win32)
 

Hola,
On the middletier side, midas.dll. On the client side you can use midas.dll
or compile your applications with the midaslib unit.

How do I make the functions inside a DLL available to my project? I am
using BCB6 personnal and XP. I hope I have the correct group, maybe this
should go into IDE.

The answer depends both upon the DLL begin used and how you decide to use
it.
If the DLL is a package, an item created with C++ Builder or Delphi which
exports functions or classes in a program using the VCL then the compiler
documentation gives a description of how to use it.
If it is not a package then it is a normal DLL. The simple answer, assuming
that everything is already perfectly set up for you, is to include the
header file into your project and add the import library for the DLL to the
project. Unfortunately the situation is not always perfectly set up.
If it came from someone else then that person or company will supply a
header file which contains prototypes of the functions exported by the DLL.
If you wrote the DLL then you can get these function descriptions from its
source code. You can link to it implicitly or explicitly. Here is a link
to pages which go through an example of creating and using a simple, demo
DLL.
www.mulroy.org/howto10.htm
The demo creates a console mode program using the compiler's command line
tools. You could use the IDE to do it if you create the DLL and demo
program projects as console mode (File|New|Other->double click on
Console_Wizard). After reviewing the page at that link, it might be useful
to go through the whole set of pages starting at:
www.mulroy.org/howto.htm

Thanks for coming back to me with the information and links. I think it is
a normal dll. I used implib to create a lib file from the dll and included
it in the project but I do not have a header file. I will try to get some
information from the dll supplier about this.
