Using .dll in QT
I survey some documents. I only know maybe I can use "QLibrary" to take symbol in my .dll. Now the problem is how can I use symbol in my .dll.For example if I had a class named "TakeIt", how should I do that I can use this class in my QT!?? Thanks.
If it's your own dll, then you have the corresponding includes and lib file thus you can use the same technique like for any other framework.
INCLUDEPATH += path_to_your_includes
LIBS += -Lpath_to_your_lib_file -llibrary_name
Thanks. It's not my dll which release from manufacturer. I checked document about "QLibrary", does it only can use on "function" symbol? Because I implemented on other framework, I just set up reference and I can call the whole class that I want in my program.So, I want to know if I call class which is packeted into .dll file, how should I do in QT??
the managed dll which is generated by .net framework can not be access by native C++ directly. So it can not be used in Qt directly.
You need to use C or C++ API provided by the device manufacturer or OS.
Thanks. I see: )).By the way, if I want to use whole class in .dll file or .lib file from C or C++, I just do that SGaist said and include .h file, right!?
