How can I make my program wait a set period of time before resuming execution without Sleep. The problem with Sleep is that the user interface freezes.Example:Set Db = dbengine.opendatabase(datapath)' Wait 4 seconds Set rs =....----------------------This is not a real use, as their is no reason to wait for the database to load, but it does show what I want.

Use the DoEvents.
 
DoEvents yields execution so that the operating system can process other events.

The DoEvents function returns the number of open forms.
DoEvents passes control to the operating system.  Control is not returned until the operating system has finished processing the events in its queue and  all keys in the SendKeys queue have been sent.
If parts of your code take up a lot of processor time, use DoEvents periodically to relinquish control to the operating system so that events, such as keyboard input and mouse clicks, can be processed without significant delay.

And here a example:

'*************************************
Set Db = dbengine.opendatabase(datapath)
Doevents
-
-
any thing that you want
-
-
'************************

Wait more time ...

Dim i as integer

Set Db = dbengine.opendatabase(datapath)

for i = 1 to 20
    Doevents
next i
-
-
any thing that you want
-
-
'************************
