Statically linking third party dll(no .lib file) and use classes using qt

[RachanaKalaskar]

Hi,

Actually same dll file is properly working in visual studio. Required classes are exported and used in that application just by using namespace and adding reference of that dll file.
So I need to use same dll in qt application. I have linked that dll in my application but still unable to use namespace.
Is header file required for using namespace and using classes in application ?


Thanks for help.

Is your DLL a COM DLL? Then you need to #import the type library into your app. Is your VS project a .Net app? That's what adding the reference in VS is doing for you behind the scenes.

You still cannot link to it statically. It's a DLL. Your VS app is loading it at runtime even if you don't think so. Build your app, then move the DLL somewhere (or rename it temporarily), then run your app without rebuilding. It will tell you it can't find the DLL.
