Return Value of GetExtension method

User (Legacy)

Recommended Posts


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,


- call "AddExtension" and afterwards "Import"

- call "Import" and afterwards "AddExtension"

Do you have any suggestions?
