MS Office Forum / Word / Programming / March 2005Problem with ActiveX having another object as property!!!
hi! i have an activeX control for MS Word. this activeX control has few properties including an object as a property. i create this inner object when the ActiveX control is inserted into Word. i.e in the InitNew function. then i store some data into this Inner object's property. I press save button but when i go to close the document, it again ask me "Do you want to save Doc4". if i click yes. document is closed but when i check the contents of Inner object in DocFile Viewer. its empty. i don't know why it happens. furthermore if i reopen a document which contains my ActiveX control. how can i get the data from inner Object's property. i m using VC7.1 ,ATL COM Ahmad Jalil Qarshi > i have an activeX control for MS Word. this activeX control has few > properties including an object as a property. i create this inner [quoted text clipped - 5 lines] > Viewer. its empty. > i don't know why it happens. Does your inner object implement a persistence interface such as IPersistStreamInit? Do you list it in the control's property map?  SignatureWith best wishes, Igor Tandetnik With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925 Thanks Igor. yes i have implemented the persistance interface and also listed the inner object as property in the COM_PROP_MAP of control. The thing which irritate me is that if i insert some data into the property of the control and then after saving the document when i go to close the Word y it again asks me "Do you want to save Doc".

Looks like a problem with how IPersistStreamInit::IsDirty is implemented. Check that after the control is saved for the first time, IsDirty returns false both for the control itself and for the inner object. If it does not, try to figure out why not.
