I have an online mysql Database that I am accessing through C++. Is there a difference if I do Version 1 or Version 2? I know thw syntax and other stuff is off, but I'm just trying to get the framework...Any suggestions are welcome....

FIRST VERSION

Field 1 = DCount("IP", "tblURLIP", "IP = 192.168.1.168")
Field 2 = DCount("IPStatus", "tblURLIP", "IP = 192.168.1.168 And IPStatus = 1")
Field 3 = DLookUp("IPMax", "tblURLIP", "IP = 192.168.1.168")
Field 4 = DSum("IPDown", "tblIPAccess", "IP = 192.168.1.168")

If Field 4 <= Field 3 Then
Field 5 = 1
Else
Field 5 = 0
End If

If Field 1 + Field 2 + Field 5 = 3 Then
"Proceed"
Else
"Quit"
End If

SECOND VERSION

Field 1 = DCount("IP", "tblURLIP", "IP = 192.168.1.168")
Field 2 = DCount("IPStatus", "tblURLIP", "IP = 192.168.1.168 And IPStatus = 1")
Field 3 = DLookUp("IPMax", "tblURLIP", "IP = 192.168.1.168")
Field 4 = DSum("IPDown", "tblIPAccess", "IP = 192.168.1.168")

If Field 1 = 1 Then
 If Field 2 = 1 Then
	If Field 3 <= Field 4 Then
	  "Proceed"
        Else
	  "Quit"
	End If

Sorry but what is the relation between your code and C++ MySQL?
From what I see it's VB/VBA and MS Access?

Like I said, it's only filler code. I'm trying to nail down which structure would be better.

How about:

if(Field1 != 1 || Field2 != 1 || Field3 > Field4)
    "Quit"
else
    "Proceed"

That way as soon as you find out one of the conditions fails you can quit, and you won't need multiple (separate) if statements.
I'd advise against using something like If Field 1 + Field 2 + Field 5 = 3 Then, even if your quite sure of what the fields will be if something changes in the future you might end up with some unexpected behaviour, like if Field1 = 2, Field2 = 0 and Field5 = 1 it would still go through.
