How to use Windowless ActiveX.dll in my project
Please support our VB.NET advertiser: Intel Parallel Studio Home
 |
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?
I don't think there is anyway to fake it.
