VB.Net, Dynamically add ActiveX control to VB.NET Form

Dynamically add ActiveX control to VB.NET Form

Author	Message
Ewart MacLuca #1 / 4	Dynamically add ActiveX control to VB.NET Form Our current VB6 application dynamically adds ActiveX controls to child MDI forms following the "Dynamic MDI Forms" approach published in the March Visual Basic Programmers Journal, available in MSDN. We are trying to port this application to VB.NET, but we can not figure out how to dynamically load our forms which are COM based onto a VB.NET form. We can sucessfully dynamically create a COM object from VB.NET like so: ObjectType = type.GetTypeFromProgID("projectname.classname") NewObject = Activator.CreateInstance(ObjectType) But the succcess ends there. Any suggestions? Is this even possible? In desperation.. Cheers, Ewart. keywords: OCX user controls, COM forms

Ewart MacLuca #3 / 4	Dynamically add ActiveX control to VB.NET Form Thanks Bob, I looked at that but unfortuantely that article does not truly describe how to DYNAMICALLY load controls. I need to load it dynamically rather than creating a reference at design time - the control will not exist at design time. anyone got any ideas? seems Microsoft have {filter}ed up this part of the design for .net rgds, ewart.

Rob Oeffn #4 / 4	Dynamically add ActiveX control to VB.NET Form Hi Ewart, Not sure if I'm on the right track and if this of any help. But what I do is to reference the particular ActiveX control in my project by adding it to the toolbox which is available when displaying a form in the designer in the .net IDE. Subsequently I create an instance of the activeX control just as I would in VB6 by adding it to the form: ' only got IDispatch here MyActiveXobj = New AxMyCtrlObjLib.AxMyCtrlObj() ' ActiveX obj must connect to the container's interfaces when ' put on the container. Otherwise it doesn't know where it is Me.Controls.Add(MyActiveXobj) ' do something with the control MyActiveXobj.left = 0 MyActiveXobj.top = 42 MyActiveXobj.DoIt I think this should instantiate your ActiveX control properly.
