When need "DoEvents" and/or "Sleep"

I have question:

When need "DoEvents" or "Sleep"

any advice if this example, need "DoEvents" ?

Code:

---

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

---

no need for this code
read this to know abt DoEvents

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"

link may be useful for u.

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.

Good to know. Thanks for info.
