Return Value of GetExtension method

[User (Legacy)]

Hello,

I am using ChartFX Client Server with Access 97. I am trying to load an 

existing configuration and then use the GetExtension method. As the method 

returns the data type "unknown", I have to declare the receiving variable 

as "Variant":

dim a as Variant

' load previous annotations

chart.Import CHART_CFXOLEFILE, fileName

' try tro get handle

set a = chart.GetExtension("AnnotationX.AnnList")

' add further annotations ...

This "Variant" type is useless for me, as I can not invoke methods on it. I 

tried other possibilities, but all of them resulted in Access crashing, 

e.g.:

- call "AddExtension" and afterwards "Import"

- call "Import" and afterwards "AddExtension"

Do you have any suggestions?

Thanks,

Florian

GetExtension returns a dispatch object (COM), which can be programmed using 

automation.

I don't know much about Access 97, but in VB you do:

Dim a as object

set a = chart.GetExtension("AnnotationX.AnnList")

a.ToolBar = true
