How to use a dll function

[andre]

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

[andre]

Sorry, I don't understand the question.

[aldoduju]

code in the above described i: = Cardinal.

Cardinal is a type of data used in Delphi, I wonder what kind of data coresponding Qt

[andre]

Basically, it is an unsigned 32 bits integer, in the current version of Delphi, if I can trust what a quick Google search tells me. quint32 would be the compatible type in Qt on all platforms.

Are you asking for advice on how to port the Delphi/Pascal code to C++/Qt?

[giesbert]

If I understood correctly, you want to use existing Delphi/Pascal code within Qt? Or is it more like what Volker asked?

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.

[aldoduju]

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
