Runtime 429 ActiveX can't create object

Thanks for reading.

I have spent the best part of a day trying to untangle the follwoing and I just cannot see it I'm afraid.

BioxScan_WBF (BioScan_WBFGeneric.dll ActiveX) is registered and it appears in this test app references. The test app is throwing the 429 error as below.

Code:

---

Option Explicit

Private WithEvents ObjWinBio As BioxScan_WBF

Private Declare Sub Sleep Lib "kernel32.dll" (ByVal dwMilliseconds As Long)
 
Private Sub cmdDeviceOpen_Click()

'    Dim ObjWinBio As Object
    Set ObjWinBio = New BioxScan_WBF    <<<<<<<<  error  429
    Dim Result_ As BioxScan_Status
    Dim devinfo
   
    Result_ = ObjWinBio.OpenDevice

---

The odd this is that ObjWinBio is actually showing the internal fucntions for example if I type ObjWinBio. it lists the exposed items.


BioScan_WBFGeneric.dll is an ActiveX project and contains the following (in part)

Code:

---


Option Explicit
'
' This implements the IScanDevice interface.
Implements IScanDevice

Private WithEvents ObjWinBio As WinBioNET.BioxScan_WBF    '' BioxScan_WBF  is the name passed from WinBioNET which is a C# project referenced as a .tlb

Appreciate the help and happy to provide anything requested.

32 vs. 64-Bit?

Windows 10 64bit if that is what you are asking.
32bit compiles, dll's etc.
Thanks

Is BioxScan_WBF something you made in VB6? If so, try to unregister it, then re-register. Note that VB6 auto registers ActiveX files when you compile them. Check Project-->References, and look for duplicates. You should see only one. If you see more, you may need to do some cleanup.

Thanks for teh reply.

Yes correct, BioxScan_WBF (BioScan_WBFGeneric.dll ActiveX) is my VB6 code.

I have checked all the usual suspects. Also previously ran the RegistryFirstAid app do find and delete all registry items to get rid of everything related and then reregistered it. Still the same outcome.

I have a couple of other similar dll's and they are working Ok. This one is just being difficult for some odd reason.

Try removing the underscore from your ActiveX DLL class since VB6 adds another underscore for the event name and you can't have two underscores.
