UnattachedWindow.mbx is an MapInfo Pro addin sample for re-parenting a document window into an addin control. This sample will not run in an integrated mapping application using Do, method.
For trying out this sample, you would have to run it in MapInfo Pro 64 bit version.
Did you manage to run MapInfo x64 in Delphi (x32)?Could you share some code?ThanksRoman
