When need "DoEvents" and/or "Sleep"

[rpool]

I have question:

When need "DoEvents" or "Sleep"

any advice if this example, need "DoEvents" ?

Private Sub Command1_Click()
Dim a As Integer
Dim b As Integer
Dim c As Integer
Dim d As Integer

a = 6
b = 7

c = a + b
DoEvents

d = c * c
DoEvents

MsgBox d



End Sub

I was read. but general , open/read/write file. database ado connect. use some OCX (WebBrowser1" that
need "DoEvents" no else ?

Also, "DoEvents" is avaible set TIMEOUT ?
if WebBrowser1 no any response after 60sec,
open/read/write file/database too large, over 100MB, and still use 60sec
kill it, msgbox "error"

Not sure what you're asking but the purpose of DoEvents is not to create a pause/delay. If you're looking for a method of inserting a pause the Sleep API (as a stand alone function) sucks. Without additional code, Sleep will make your app comatose.

The WaitMessage API is a far better choice. It --needs DoEvents to function though.

If you truly want a "sleep" or "wait", as an alternative to CDrive's
suggestion, check out RhinoBull's snippet in this thread (post #2):

That is a very common method but it's a CPU hog. The WaitMessage API is the opposite.
