Problem loading external dll

then why don't just say you don't know neither. putting useless answer here is also a wasting of time!

@angyingmm:
If you look at wysotas stats (right corner of any of his posts header) you will see he has about 26500 posts (at time of writing this post).
More importantly, he has ~3800 Thanked posts!
I wouldn't, with my 4th!! posts on this forum go and say he "doesn't know" or, that he posts "useless answers".
However, it is "useless" to post questions which are not Qt related in a Qt Programming forum.
Moreover, he DID gave you the answer, one you either don't quite understand or too lazy to follow - neither is a reason to slash out.

Above was meant as a friendly tip.

I guess a friendly tip is to give people answer on the thing they need help rather than let them search Google. I do appreciate and admire people here who have knowledge and are willing to share with others. That’s why I come here and ask, but unfortunately met people either can't quite understand the problem, or too lazy to answer. same, neither is a reason to putting the problem out off Qt.

It IS a QT related question! I DO know how to do it with a normal .net project, but not a Qt project. that's why I ask here.

No, it's not related to Qt. Remove all Qt code from your app, take any 3rd party library unavailable by default on the target machine and you'll have the exact same problem. If you know how to solve it there, solve it the same way here. Your problem manifests itself BEFORE the application is executed thus how can it be related to what is INSIDE the application? If you don't believe then remove all code from main(), leave just a simple std::cout << "Hello" << std::endl; and see if it gets printed. If it's not then you should come to a conclusion that whatever you write as code of your program will not help your situation in any way (and thus since not a single line of Qt code was executed, this is not a problem related to Qt).
