dynamicCall and QByteArray - strange characters

[wysota]

I meant the ArrayList (or its C++ equivalent) or whatever the return type of the call should be.

Do you mean something like this?
QList<QString> list = static_cast<QList<QString>>(ba.data()) ?

[wysota]

No, I meant the structure you would be getting if you were calling the method directly using WinAPI's COM API. I just can't say it more clearly. Or just dump the byte array to the console in ascii, see what is there and try to guess its stucture.

If I can try to put it a bit more clearly:

Your dynamic call returns a QByteArray with 441 elements right? So all those return types (CardID, OverWrite, idxDesignation and all those) you listed should be contained in those 441 elements.
What wysota means by structure is how those 441 elements are divided to produce the return types ie. CardID is a string of size 10, OverWrite a byte(or bit) etc... If you have that structure you can try to cast the QByteArray to that structure. Otherwise you'll need to determine the structure as wysota mentioned - by dumping to ascii and trying to figure out the type of each return type.

If I well understood I have to first create such structure with struct and then cast the returned value to such structure? Or I'm wrong?
Can I have some pseudo-code?

Did you try entering "ArrayList C++" in your favourite search engine and reading what pops up?

The arrayList is not the problem. The problem is the return value that's QByteArray
