Hi,

I read this thread:
http://www.qtcentre.org/threads/8276-Excel-using-Qt

and I read also this page:

http://qt-project.org/forums/viewthread/1871


In my application I wrote only this line:

#include <QAxObject>

......
.....

QAxObject * excel = new QAxObject( "Excel.Application", 0 );

and I have 3 errors:

1) C:\Documents and Settings\Giuseppe\Applicativi QT\Excel-build-desktop-Qt_4_8_0_for_Desktop_-_MSVC2008__Qt_SDK__Debug\..\Excel\mainwindow.cpp:2 4: warning: C4189: 'excel' : local variable is initialized but not reference

2) mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall QAxObject::QAxObject(class QString const &,class QObject *)" (??0QAxObject@@QAE@ABVQString@@PAVQObject@@@Z) referenced in function "private: void __thiscall MainWindow:n_pushButton_clicked(void)" (?on_pushButton_clicked@MainWindow@@AAEXXZ)

3) debug\Excel.exe:-1: error: LNK1120: 1 unresolved externals

WHY ??????????????!!!!!!!!!!!!!
