Find controls inside a tabcontrol

[somaauto]

We have a tab control and inside that there is another control containing many objects. We want to select each object inside the inner control. But AutoIT Window Info Tool is not able to recognize this inner control. Please guide us  how to identify  the inner control and select each object inside it.
