change viewport update status?

[michaelk]

Is this a bad idea??

I'd like to be able to reset the "need to update" status on sheet layer viewports.

There are many times when I change the manufacturer's model number in a worksheet and a most of the SL viewports show the red barber pole lines. Or I change the graphic attributes of a section line and the section viewport (unnecessarily) shows that it needs to be updated.

Has anyone ever tried this?

Are there any problems to be aware of?

Is this the correct procedure: SetObjectVariableBoolean(SLViewportHandle,122,FALSE)

Thanks

MK

Another related question.

Below is a quote from the VS reference for SetObjectVariableBoolean

The description of the procedure has a handle argument, but the example doesn't.

It won't run without the handle argument, but it doesn't change the boolean variable with it.

In the Object Preference Selectors, 17 is a real and is for Dimension Font Text Size.

What Boolean Object Preference Selector are you really trying to set?

If you download the SDK and look in MiniCADCallBacks.h you will see that 1004 is a read only parameter.
