Here is a quick summary for your reference:
You encountered a problem in which ATL based ActiveX Control was getting set to zero size draw area in some versions of IE Mobile.
We tracked down the problem to a bug in versions of IE Mobile which have the �Zoom Level� menu option.
We identified a change that can be implemented in the control to work-around the problem and which does not appear to cause problems on other browsers, which don�t have the bug.
The problem can be worked around by overriding the InPlaceActivate implementation, of "CComControlBase", in the control code. The work-around is described below:
To override InPlaceActivate :
1) Add the following function to your control class: "HRESULT InPlaceActivate(long iVerb, const RECT* prcPosRect)" to your control class.
(if using the "Add Member Function Wizard"
* set "Return type:" to "HRESULT"
* set "Function name:" to "InPlaceActivate"
> First Parameter:
* set "Parameter type:" to "long"
* set "Parameter name:" to "iVerb"
* click "Add"
> Second Parameter:
* set "Parameter type:" to "const RECT*"
* set "Parameter name:" to "prcPosRect"
* click "Add"
* click "Finish"
2) copy the implementation of "CComControlBase::InPlaceActivate" from "atlctl.h" into your new function, replacing the existing content.
("...\VC\ce\atlmfc\include\atlctl.h")
3) In in the code you copied search for the call to "CreateControlWindow"
4) add the following code *before* the call to "CreateControlWindow":
if (rcPos.right == rcPos.left && rcPos.bottom == rcPos.top)
{
rcPos = rcClip = m_rcPos;
}
// now call CreateControlWindow...
5) save your changes and rebuild the control.
