i think it should work using pluginloader something like below:
QObject* getPrmt(QString path)
{
QDir pluginsDir(path)
QPluginLoader loader(pluginsDir.absoluteFilePath(fileName));
return loader.instance();
}
and call getPrmt function with any of A/Prmt.dll, B/Prmt.dll?

Hi manish,
Thanks for the reply.
I am totally new to QPlugin and QLibrary.
I don't quite understand your meaning.
With your method below, can I load A/Prmt.dll then unload
A/Prmt.dll and then load B/Prmt.dll in runtime without
I think you might have to design your application something like below:
For instance all the Prmt.dlls should implement a common interface for
instance: PrmtInterface and place it under PrmtInterface.h
And your Core.dll only know about PrmtInterface.h, it should not link to
any of the Prmt.dll.

Thanks a lot!
I have already implemented Core.dll and Prmt.dll in the way you suggested.
Will learn how to use QPluginLoder for such case.
If anyone can provide a sample code, that would be greatly helpful. :)

Not a good idea. Unloading plugins is not recommended. Simply restart the
application
