[english_dany]

Hello Guys,
I am developing QT based project in VS2008, It working fine apart from one problem that when I try to use a custom DLL file its give me quite a few errors which I cannot understand ,
As soon as i include the header file with the statement

#include "DTKANPR.h"
It gives me these errors

Hello guys ,
Its again me, I think i found the solution for this problem , It took me one week to find this simple answer,
The problem was about putting the header file in the right place, I put the header file instead of my class my put that in my first project file.
If you are getting the same error ,I will recommend to find a place where you think your compiler starts to read for the header file the very first point and place your header file over there and i think should work, but most of the time the problem solves when you include <windows.h> before before the header file. Hope this post will help someone out there .. Cheers Bye
