ScreenUpdating

[SRSDS]

Is there a way to turn off screenupdating until a process is complete.

Similar to Application.ScreenUpdating = False used in Excel.

I make changes to several blocks and you can watch as it moves through each one. I'm guessing it might be faster if the drawing doesn't redraw after each.

I posted the solution here

Not sure about test this code as well

Sub test()

Dim tm as TransactionManger =doc.TransactionManager

For Each....

'' [ the rest your code here ]

Next

' then before of committing the transaction add these lines:

tm.QueueForGraphicsFlush()

tm.FlushGraphics()

ed.UpdateScreen()

tr.Commit()

End Sub

I have all my routines starting and finishing  transactions which is possibly be the problem after reading through the thread arcticad posted.

Rearrange things to do everything under a single transaction might be the answer.

If not I'll try both your methods.

Frighteningly slow. You have to sit back and wait for it do it's thing.
