I have ole enabled container which has active-x.When i click the GUI of Active-x control, the control inturn should fire event passing a string value to the container.Now i have created the custom event in the active-x control.Now when the event is fired i am able to get the string to the container but only the first charecter i want the entire string.How to get the entire string? listing as follows

Active-x control
BEGIN_EVENT_MAP(CFilterCtrl, COleControl)
     //{{AFX_EVENT_MAP(CFilterCtrl)
     EVENT_CUSTOM("Group", FireGroup, VTS_BSTR)
     //}}AFX_EVENT_MAP
END_EVENT_MAP()

void FireGroup(BSTR bstrVal)
{FireEvent(eventidGroup,EVENT_PARAM(VTS_BSTR),bstrVal);}
DECLARE_EVENT_MAP()

//when this control is clicked

COleVariant varVal(group.m_DisplayName);
varVal.ChangeType( VT_BSTR );
FireGroup(varVal.bstrVal);


///////// container ///////////////
BEGIN_EVENTSINK_MAP(CMISReportView, CFormView)

END_EVENTSINK_MAP()

afx_msg void OnGroup(BSTR bstrGroup)
DECLARE_EVENTSINK_MAP()

void CMISReportView::OnGroup(BSTR bstrGroup)
{
     COleVariant varVal((LPCTSTR)bstrGroup);
     varVal.ChangeType( VT_BSTR );
     MessageBox((char *)varVal.bstrVal);// ONELY THE FIRST CHARACTER IS OBTAINED
     theApp.m_strGpNames = (LPCTSTR)bstrGroup;
}

Answer : passing string to container from Active-X

What with what I have given you don't you understand - the answer is there or should be - does it not work?



void CMISReportView::OnGroup(BSTR bstrGroup)
{
 theApp.m_strGpNames = (LPCWSTR)bstrGroup;
 MessageBox(theApp.m_strGpNames);
}
