FIX: CIRC2 and CIRC3 Samples Don't Handle WM_SIZE Message

Back to the top

Sample Code to Implement Workaround

void CCirc2Ctrl::OnSize(UINT nType, int cx, int cy)
{
    COleControl::OnSize(nType, cx, cy);

    // If circle shape is true and circle does not fit in new size, reset
    // the offset

    if(m_circleShape && !InBounds(GetCircleOffset()))
       SetCircleOffset(0);
}

Steps to Reproduce Problem

1. Build either the Circ2 or Circ3 sample.
2. On the Tools menu, click Register Control, and verify that the control registers successfully.
3. On the Tools menu, click Test Container.
4. On the Edit menu, click Insert OLE Control, and then click the control that was built in step 1.
5. Resize the control to a rather long rectangle.
6. On the View menu, click Properties, and change the CircleOffset property to 100 pixels to decentralize the circle.
7. Resize the control to force the circle outside the rectangle.
8. Notice that the circle is drawn outside the rectangle.
