How to use Windowless ActiveX.dll in my project

Expand Post »

Hello,
I am trying to use a ActiveX component (written by someone else) in my Visual Basic 2005 project. I am new to VB2005, so please bear with me.

I added the COM reference to the ActiveX.dll class to the project.
I choose the Toolbox Items from COM Components Tab and added the ActiveX component to the General Toolbox.
I am able to place this ActiveX component in the Main.vb form, I can see the object's properties but I encounter a problem when I attempt to run (F5) the project. I get the following error:

at System.Windows.Forms.UnsafeNativeMethods.IOleObject.DoVerb(Int32 iVerb, IntPtr lpmsg, IOleClientSite pActiveSite, Int32 lindex, IntPtr hwndParent, COMRECT lprcPosRect)
at System.Windows.Forms.AxHost.DoVerb(Int32 verb)
at System.Windows.Forms.AxHost.InPlaceActivate()
Unable to get window handle.. Windowless ActiveX are not supported.

What am I doing wrong? Your help is greatly appreciated.

Thank you.

The last line tells you, you can't. Is it windowless or is vb not seeing the window?

VB.NET Syntax (Toggle Plain Text)
Unable to get window handle.. Windowless ActiveX are not supported.

I don't think there is anyway to fake it.
