In excel VBA.
For example, - If cells(i,1)=1 Then
-
Call Procedure1
-
Call Procedure2
-
End If
-
If ....
-
...
-
End If
-
Loop
The Procedure1 and 2 will execute every loop, but I only want the Procedure1 excutes once, and the procedure2 excutes everyloop. How can I do that?
thanks

Probably the simplest way is to create a variable which you use to "flag" the fact procedure 1 has been run. Each time 'round the loop, if the flag hasn't been set, then run procedure 1 and set the flag.

what is flag? I try to figure out "Flag" a long time ago, but still can't.

The term "flag" just refers to a variable that you use to indicate a particular situation. In this case, a boolean variable that you would set to True to indicate that you have performed the thing you only want to do once.
Here's some pseudo-code showing a general example (based on your situation) of the way a flag might be used... - Clear flag (set to False)
-
Start loop
-
If Flag is not set Then
-
Do Proc1
-
Set flag (set value to True)
-
End If
-
Do Proc2
-
End Loop

Hi,
I have a combo box in a form. It has limit to list set to "yes", and

Now, my problem is that, even though when I enter a value not on the
list it appropriately opens the form to add a new value, the pop-up
that says "The text you entered isn't an item in the list" still
comes up. This seems pretty unreasonable since I already wrote an

I plan to include in default.asp a routine to check if the annual
subscription is due from the records in the People table.
If so, then the routine would send emails to those who are due and update
the table that this had been done, so that it is only done once.
If session 1 is doing just this, session 2 (and 3 and n) could be doing the
same thing.

Hello
In visual studio when I am debugging my ASP. net code if I hit "stop"
the procedure I am in will still finish itself and doesn't stop where
I expect it to stop.
I remember in VB when you stop your code it stop at the exact line
you're on. Now if I stop at the beginning at the procedure or function
the code will still continue until the end sub/end function.
