How to use a dll function
-
Ok, so it really is about making use of an external .dll in a Qt application. What about Gerolfs contribution above isn't clear in this context? The point is that you need to make sure you export your application in a way that makes reuse from another application in another language possible. How you do that, is not Qt specific but something you need to look into for delphi.

I'll try to be clear, I would like to write a dll in transposing this procedure for Qt C + + Qt if it is not possible in this case I tereria that make use of it externally.
one has to create a dll with this procedure implemented in Qt?

No, you can use external dll's in Qt (or any other C++) applications. However, that dll needs to meet certain criteria, depending on the way you wish to use that dll. Gerolf talked about these criteria, and I suggest you search in dephi resources how to achieve this. The keyword to search for is exporting functions.

and changed the focus, I noticed that it is easier to make the dll in the same Qt.
I wonder what kind of data to corespondete (Cardinal of Delphi) to Qt?
graciously
-
code in the above described i: = Cardinal.
Cardinal is a type of data used in Delphi, I wonder what kind of data coresponding Qt
-
Are you asking for advice on how to port the Delphi/Pascal code to C++/Qt?

From this posting, I gather that aldoduju has changed his mind, and now instead of wanting to use a delphi-build dll in a Qt program, now wants to port his code to Qt and build the dll in Qt. -
Yes, at first I wanted to use to access the dll made in Delphi, now I want to create this dll
code in C + + Qt
