Hi,

I dont know if this is the group for ActiveX but there is some
activity at this group so anyway..

I have a created an ocx skeleton :

void CChatTextEntryCtrl::OnDraw(
            CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
    // TODO: Replace the following code with your own drawing code.

    pdc->FillRect(rcBounds,
CBrush::FromHandle((HBRUSH)GetStockObject(WHITE_BRUSH)));
// pdc->Ellipse(rcBounds);

    pdc->TextOut (0,10,o_Str);

}

and a method assigning a string value to a CString o_Str member of the
controlclass.

void CChatTextEntryCtrl::SetText(LPCTSTR s_Str)
{
    // TODO: Add your dispatch handler code here
    o_Str = s_Str;

}

I just want the string i send from a dialog app or activex-test-
container to be displayed in OnDraw, so on the CDC protion of the
control. I does not ! How do i write text on the controls visible
portion using an automation method discribed above ?

Is the OnDraw called? (Check with debugger.)

If not, add a call to Invalidate() where you set the text. Invalidate()
causes a later call to OnDraw.
