The information in this article applies to:
- Microsoft Windows CE Toolkit for Visual C++ 6.0
-------------------------------------------------------------------------------
SYMPTOMS
========
After installing the Microsoft Windows CE Toolkit for Visual C++ 6.0, if you
right-click on an ATL class in the Class View pane, the "Add Windows Message
Handler" wizard always displays empty. The wizard is supposed to have a list of
windows messages and events you can select to add a handler for. On a computer
without Microsoft Windows CE Toolkit for Visual C++ 6.0, the "Add Windows
Message Handler" wizard had numerous messages/events to choose from.
CAUSE
=====
Microsoft is researching this problem and will post more information here in the
Microsoft Knowledge Base when it becomes available.
RESOLUTION
==========
At this time, there is no resolution to this problem other than uninstalling the
toolkit, and doing a clean uninstall and reinstall of Microsoft Visual C++ 6.0
or Microsoft Visual Studio 6.0. To workaround this problem, message maps can be
added manually without using any wizards. For example:
class CMyClass : ...
{
public:
...
BEGIN_MSG_MAP(CMyClass)
COMMAND_HANDLER(IDC_MYCTL, EN_CHANGE, OnChange)
MESSAGE_HANDLER(WM_PAINT, OnPaint)
...
END_MSG_MAP()
// When a CMyClass object receives a WM_COMMAND
// message identified by IDC_MYCTL and EN_CHANGE,
// the message is directed to CMyClass::OnChange
// for the actual processing.
LRESULT OnChange( ... )
{ ... }
// When a CMyClass object receives a WM_PAINT
// message, the message is directed to
// CMyClass::OnPaint for the actual processing.
LRESULT OnPaint( ... )
{ ... }
};
MORE INFORMATION
================
Steps to Reproduce Behavior
---------------------------
1. Create a New ATL/COM AppWizard project.
2. From Menu item, choose Insert, New ATL Object... and choose the Miscellaneous
Category and then add a Dialog object.
3. In the Class View right-click the Dialog Class and choose Add Windows Message
Handler.
If Windows CE Toolkit for Visual C++ 6.0 is installed on the computer, you will
notice that the "New Windows messages/event" list is empty.
