Xtreme Command Bars ActiveX 2012 (15.3.1)

Dev Environment VB6 Service Pack 6

Windows 7 both 32 and 64 bit versions

I have an application written in VB6 which utilizes the command bar object to create a ribbon bar menu system. All of this works without a problem but when I attempt to add a DialogBar object my application crashes with the following error:

Run-time error ‘-2147417848 (80010108)

Method ‘ChildHandle’ of object ‘IDialogBar’ failed

This crash only occurs on 32bit Windows7

Here is a code snippet of where the crash occurs:

Set DialogBarActiveRecords = CommandBars.AddDialogBar("ActiveRecordsGrid", xtpBarRight)

DialogBarActiveRecords.ShowCaption = False

DialogBarActiveRecords.ShowGripper = False

DialogBarActiveRecords.Closeable = False

DialogBarActiveRecords.ChildHandle = Me.mainPic.hWnd

mainPic is a standard picture control which contains several other controls. If I remove all controls contained in mainPic the application still crashes.

Any help would be appreciated

Are you sure Me.mainPic.hWnd is a valid handle? Are you sure this PC has SP6 on it? Please check the handle and ensure its valid.

Yes me.mainPic.hWnd is a valid handle and the machine in question has SP6 installed. I added a bit more information don't know if you saw it in the issue I submitted. What I added was this:

Our application is MDI based, on the MDI form we align the picture control (mainPic) top, left. It is when the picture control is aligned this way it crashes when setting the dialogbar childhandle property. And this still only affects 32 bit win 7 not sure about win xp.

Thanks

I tried the code in VB6 SP6 on Win7 and XP (32-bit only), same version of the controls, and I'm not seeing the error.

Maybe you should try to re-register/re-install the OCX?
