How to check IGS for availability?

Hi all,

does anybody know a way to check the availability of an IGS with WD 7.1, e.g. check the configured URL? If any configured... How to find/retrieve this URL-WD-property ?

...or some function to call on BusinessGraphic control?

I want to avoid the "Graphics rendering problem"-picture, i.e. hide the Business Graphics element if there's no IGS.

Thanks for all replies.

Best rgds,

Bastian
