I have a VB6 executable that references a .NET 2.0 dll.

method of a button.  I would like to set the position of this new form on
the window, but I can't figure out what method to call or property to set to

const int LWA_ALPHA = 0x00000002;

cleaner way to change the object instance it's called on other than invoking
"Delegate.CreateDelegate()" (and changing the object instance while leaving
the same member function intact). Thanks in advance.
