Question:
How do I get a ComboBox to drop down its list box in code?

Answer:
Send the ComboBox a CB_SHOWDROPDOWN message, passing a 1 (true) in
the WParam parameter to drop the list down, or a 0 (false) to hide it.

Example:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    SendMessage(ComboBox1->Handle,CB_SHOWDROPDOWN,1,0);
    ComboBox1->SetFocus();
}
