visCmdDrawZoom seems to fail with "Number is not valid"

[HarryH]

I have Visio OCX in my application and I am attempting to perform a Zoom
operation which uses visCmdDrawZoom, but I get an error.

The call in C# is basically:
IOLeCommandTarget cmdTgt = drawingControl.GetOcx();
cmdTgt.Exec(ref VisioCommandHandlerCollection.CLSID_Application,
visCmdDrawZoom, 0, null, null);

This exec call fails with an error message "Number is not valid.".

Any ideas why I am getting this result as all other Visio (Zoom) commands
execute fine?

Thanks.

visCmdDrawZoom seems not valid even in Visio2003 DoCmd method.
You might be better to chooze another way.

What about setting the Zoom property of the Window?

Setting the zoom property of the window seems to work fine.

In fact all zoom operations seem to work fine - except when I try to bring
up the Zoom dialog box with "visCmdDrawZoom", and I get the error message.

I am wondering if I am missing some subtle setup operation or if this option
is broken?

Thanks.

Not all Visio commands can be invoked programmatically. This might be such
a command.

OK - thats what I perceive.

I was hoping to have some confirmation on this - Is there any way to verify
if this particular interaction has been verified?

Thanks for all assistance.
