I have a problem that is cmfctoolbar is not registered using COleDropTarget::Register(this). why it is failed to register? Please do favour by giving the rite solution.
And also ON_NOTIFY_REFLECT(TBN_DROPDOWN, OnOzoneDropDown) not working. When I do dropdown on the toolbar button OnOzoneDropDown handler is not getting call. I am using CMFCToolbar.
class COzDropTarget : public COleDropTarget
{
public:
virtual DROPEFFECT OnDragEnter( CWnd* pWnd, COleDataObject* pDataObject, DWORD dwKeyState, CPoint point) ;
virtual DROPEFFECT OnDragOver ( CWnd* pWnd, COleDataObject* pDataObject, DWORD dwKeyState, CPoint point );
virtual void OnDragLeave( CWnd* pWnd );
virtual BOOL OnDrop ( CWnd* pWnd, COleDataObject* pDataObject, DROPEFFECT dropEffect, CPoint point );
void SetParentWindow(COZoneBar* pOzBar);
COZoneBar* m_pOzBar;
};
class COZoneBar : public CMFCToolBar
{
public:
friend COzDropTarget;
COzDropTarget m_dropTarget;
};
int COZoneBar::CreateBtn()
{
if(m_dropTarget.Register(this) == 0) //registration failed
AfxMessageBox(_T("Register failed"));
m_dropTarget.SetParentWindow(this);
}
