I added a dialog and made a class of it, and complied my project.
An error msg was shown up like blow.
1>c:\winddk\3790.1830\inc\wxp\comip.h(142): error C2299: '_com_ptr_t<_IIID>::_com_ptr_t' : some error msg
1> c:\winddk\3790.1830\inc\wxp\comip.h(811) : making an instance of class being complied. Check a refer to '_com_ptr_t<_IIID>'
1>c:\winddk\3790.1830\inc\wxp\comip.h(251): error C2299: '_com_ptr_t<_IIID>::operator =' : some error msg.
* I wrote down "some error msg" instead of real msg because
VS 2010 i am using is not in English.
Probably, someone faced same situation. anyone help me.
