thanks guys, here is my situation. i have a class which hold a tree control(activex control), sure tree control offer setItemData(item, data), getITemData(item, &data); here data's type is converted to long*. i wanna store the interface pointer address in the item data, and get it back when i need. VARIANT DelegateGetData(item) { long *data; getItemData(item, data); CComVariant vt; vt.plVal = data; return vt; } CComVariant vt = DeletgateGetData(item); CComPtr spData((IMyInterface*)vt.plVal);//it there any better way here???

does the message first reach the DialogB then the ControlA last arrive ControlAA?if it's true ,could i handle it in DialogB? how?

The payload is just the XML document that the SOAP envelop exists to deliver. It's no different from any XML document. HeartFriend wrote: Without namespace undeclarations, there is a tendency for namespaces used in the SOAP envelope to stick to the payload XML when this is removed from the envelope, which can cause validation failures and other problems. For example, it can invalidate a digital signature attached to the document. This means if your xml does not use namespaces, it will inherit the SOAP namespace, and this will cause XSD's to fail, etc. Christian Graus - Microsoft MVP - C++

where from [dt:type="string"] is coming into the picture, did you specify the namespace ??? love2code

MIDL2020 seems to be a catch-all error, that is, it may be caused by a number of different reasons. Maybe this[^] can be of help. Or maybe not. -- jlr http://jlamas.blogspot.com/[^]

Like everyone said, it's a bad idea to do this, in fact, the C# compiler doesn't compile code like yours.. But the answer to your questions is to just use nVar. That'll refer to the variable in the current (or enclosing) scope. Regards Senthil _____________________________ My Blog | My Articles | WinMacro

If ur ok 2 handle Ownerdraw then just override MeasurItem and set the item hight as u like by using the struct parameter in MesureItem.
