Question

The TOleContainer can of course, insert OLE Objects like Word Documents. But it doesn’t seem to work for ActiveX. I know, of course, about Delphi’s IDE ability to create an ActiveX wrapper. What if I want to create a control without creating a wrapper and installing it into the IDE, at runtime?

The control is registered, so unlike this question, I don’t need registration-free com. I just need some idea, or some sample, of how dynamic ActiveX Containers are started.

Answer 1

The TOleContainer works with ActiveX controls, you only need pass the proper ProgID of the Activex control to the CreateObject method and then using late-binding access the properties of the ActiveX.

Check this sample which create a Windows Media Player ActiveX control inside of a TOleContainer in runtime.

OleContainer1.CreateObject('Wmplayer.OCX.7', False);
OleContainer1.OleObject.URL:='F:\Music\Iron Maiden - The number of the beast.mp3';
OleContainer1.OleObject.Controls.Play;
