ScreenUpdating

SRSDS — Tue, 28 Jun 2011 09:33:25 GMT

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.

Not sure about test this code as well

Sub test()

Dim tm as TransactionManger =doc.TransactionManager

For Each....

'' [ the rest your code here ]

' 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.
