Selecting shapes from an external dll

[bierwurst]

Hi. I am trying to select a shape from a vb .dll where I don’t have access to the activewindow library. All I have is a reference to the shape that needs to be selected.
If I try to make a new selection object like this;

set selection = shape.CreateSelection(visSelTypeAll, visSelModeOnlySub)
selection.Select shape, visSelect

Nothing happens.

Any ideas?
