Make your Button on the embedded Form public in the form editor in the IDE.
Let the Button be btnOK and an instance of your embedded Form be
"hEmbedded". Then you can do the following in FMain:

Object.Attach(hEmbedded.btnOK, Me, "btnOK")

This will attach the Button btnOK on the embedded Form to FMain. The Button
gets "btnOK" as its event name and will then raise btnOK_Click() in FMain.
