Andi From Steyr/Austri #2 / 4	__raise throws exception hi, i had the same problem. The reason is non-zero initialization of the event-data structurs ( strange Bug! ). I solved it with a workaround. Knowing that the event-data is 'behind' the last explizit data member, do this in every constructor: { size_t cSize = offsetof( class CMyClass, m_last ); cSize += sizeof( m_last ); memset( ((char)this) + cSize, 0, sizeof( class MyClass ) - cSize ); Quote: >-----Original Message----- >Hi; >When try to raise an event, gets error with following codes; >[ > event_source(native) >] >class CChMIBTreeCtrl : public CTreeCtrl >{ > DECLARE_DYNCREATE(CChMIBTreeCtrl) > __event void MyEvent(); >.. >.. >.. >}; >.. >.. >.. >void CChMIBTreeCtrl::OnNMClick(NMHDR pNMHDR, LRESULT *pResult) >{ > try > { > __raise MyEvent(); > } > catch (...) > { > } >} >Why ?....
