Custom properties not holding
Just add an entry for it using PROP_ENTRY to a proeprty map (between
BEGIN_PROP_MAP and END_PROP_MAP). If you created a control with Wizard,
property map is created for you and comments show how to add your entries to
it.

Salutation,
How do you make your custom properties persistent so that they keep their
values
when i close the current workspace?
I have a composite control and i have added one custom property (iNbrCol)
////////////////////////////////////////////////////////////////
// CmyList
class ATL_NO_VTABLE CmyList :
public CComObjectRootEx<CComSingleThreadModel>,
...
{
...
public:
int iNbrCol;
Quote:
}
STDMETHODIMP CmyList::get_NbrCol(long *pVal)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
*pVal = iNbrCol;
return S_OK;
Quote:
}
STDMETHODIMP CmyList::put_NbrCol(long newVal)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
iNbrCol = newVal;
SetDirty(true);
SendOnDataChange(0);
return S_OK;
Quote:
}
Now the value i set for this property will hold as long as i am in design
time.
Once i close the project and open it again the default value of 0 keeps
coming
back.
Obviously i need to serialize my new property (somehow).
How can i do that?
Any sample for a composite control in MSDN? (couldn't find one)
Thank you in advance,
Francois Belair
