Hi, I have been using comtypes 0.6 dynamic dispatch support with the MSHTML interfaces in Internet Explorer and Outlook Express.
I have noticed that for some reason, comtypes is unable to find some properties, yet win32com can. Specifically, using a text range object retreaved by IHTMLElement::createTextRange(), I can not access any properties that exist on the IHTMLTextRangeMetrics interface. The text range object supports IHTMLTxtRange and IHTMLTextRangeMetrics, I'm not sure about any other interfaces. I can access any property on the IHTMLTxtRange interface, but not IHTMLTextRangeMetrics. I have found a temporary solution to the problem, and that is: * In clude a comtypes.client.dynamic._Dispatch instance on the comtypes.client.lazybind.Dispatch instance, called something like '_dispatch'. *inlazybind.Dispatch.__bind: catch NameError as well as comtypes.COMError when calling iTypeComp.bind. *in lazybind.Dispatch.__getattr__: if a property can not be found with __bind (descr is None), then return getattr(self._dispatch,name). This will allow the name to be fetched using GetIDsOfNames etc. This solution fixes the problem for me, and I can now access some more of the properties. I have no idea why ITypeComp.bind cannot find the properties. Interested if anyone has any idea why this might occure, or whether this solution is appropriate.
