dBase 2019: AntViewAx.AntViewDocument

[Vasile]

Vasile,

That's peculiar.

I will have a look, but currently don't have dBase 2019 installed, so will have to get a trial version for testing that.
But before I go down that path...

Does dBase have a way to get the dispatch pointer of an ActiveX control itself?
If so then you could use that as well instead of the IDispatchPointer property.
Also can you see if the IDispatchPointer property is returning a non zero value?

Let me add some extra logging details for troubleshooting this, so that a log file at level 2 gives me some details on what is actually happening. I will email you a private version, with steps for setting the logging later today.

Yes,   .ACTIVEX1.nativeobject    // this.ACTIVEX1.nativeobject

Also can you see if the IDispatchPointer property is returning a non zero value?
Not null.  
this.ACTIVEX1.nativeobject.IDispatchPointer has a reference (pointer) to 
this.ACTIVEX1.nativeobject

Thank you
Vasile
