Freezing layers in ViewPorts

[Anonymous]

I need a better way to freeze layers in viewports. Now I am reading the xdata from the viewport to get the information then adding the layer information into the array and writing it back to the viewport. This works 99% of the time but when it does not work the viewport won't let you freeze or thaw layers no way no how and most of the time throws you out of AutoCad. Is there anybody that has had succes doing this other ways.

Have a look at vbXtender.arx (in the Downloads section of my site). The
ViewportEx object offers methods for freezing ang thawing layers in a viewport.
vbXtender is free and open source.

I looked at your ViewportEX and found several functions that look useful. Can you give me a hint on how to use them. The ones I am interested in are vpThawall and the XrefStatus. How do you pass the VP or xref to the function.

Have you taken a look at the help file that came with the program? You'll find
syntactical examples for every method and property. But here's a primer anyway.

For any extender object (they all end in 'Ex'):

Dim vx As ViewPortEx

Set vx = AcadApplication.GetInterfaceObject("vbXtender.ViewportEx")
Set vx.Viewport = myViewportObject

Each extender object has a property with the same name as the AutoCAD object it
wraps: BlockEx = AcadBlock, ViewportEx = AcadPViewPort, GroupEx = AcadGroup,
etc.
