        ' wait until the layer created, it's very slow, mornally it taks a long time to do it..
        Do While AddDrawingInfoLayer = False

Hi,

>> I got an error when add a layer after creating a new document

Sorry, I don't get exceptions when I run your code without time-loops (which should not be necessary at least).

The only idea I have is you have anything running parallel that "reacts" on layer additions/modifications, e.g. do you have the layermanager open while running your code? Or do you have any applications/apps/tools installed?

What you might try "DoEvents" instead of the time-loops:

AddDrawingInfoLayer 'if I use this line directly,then will get an error: -2147418111 Automation error
DoEvents
' wait until the layer created, it's very slow, mornally it taks a long time to do it..
'        Do While AddDrawingInfoLayer = False
'            sleepCount = sleepCount + 1
'            Wait 0.01 ' wait 0.01 second
'        Loop

And - I guess you know that - AutoCAD 2013 is not supported for Win8.

Thanks very much for your reply!

  I don't know why, if I delete wait code, then the layer cannot created, and if I change to "Wati 0", then i can work. Strange. I will test your code, thanks again!

Hi,

>> I don't know why

Again the question: do you have the layermanager open while your code runs (and crashes)?
