Advance to Next Item from Within a For-Next Loop - vba

Question

I have a For-Next loop. Within the loop I test several different criteria and if any test fails, then I am ready at that point to skip the remainder of the code in the loop and advance to the "next" item. The way I currently handle this is with a GoTo statement that takes me to the line right before "Next". I'd prefer not to use a GoTo statement, is there another way to advance to the "next" item from within a For-Next loop? TIA!
For x = 1 to 10
Test 1
If Test 1 fails then
GoTo Line1
End if
Test 2
If Test 2 fails then
GoTo Line1
End if
.
.
.
If all tests pass then
add item to array
End if
Line1:
Next

Answer 1

Unfortunately there is no continue-like statement in a for loop in vba. (The related control structure Exit For does exist but that's of no help here).
And it's good that you have reservations on using a GoTo: they do make code hard to follow.
Your best bet is to put the code in the loop in a separate function and use Exit Function within that function at appropriate points. You can even then relay error codes back to the caller so helping the code to scale.

Answer 2

Here's a workaround for the lack of a continue keyword:
For x = 1 to 10
Do
Test 1
If Test 1 fails then
Exit Do
End if
Test 2
If Test 2 fails then
Exit Do
End if
.
.
.
If all tests pass then
add item to array
End if
Loop While False
Next

Answer 3

You can use if else ladder :
For x = 1 to 10
if test 1
else if test 2
else if test 3
.
.
.
.
else
add item to array
end if
Next
Besides GoTo there is not any direct way to jump in between your code,
Hope this might help.

If you don't have too many tests, you could you use the Not condition and build a nested If statement. This should have almost the same effect as what you're asking for, since any failed test would end that If statement and move the code to the next X in your loop without executing the following tests.
Here's an example of what I mean -- a two test loop that builds an array containing the numbers 5 through 10:
Sub TestConditionalPass()
Dim intX As Integer
Dim intArray() As Integer
ReDim intArray(1)
For intX = 1 To 10
If Not intX -2 < 1 Then
If Not intX * 2 < 10 Then
ReDim Preserve intArray(UBound(intArray) + 1)
intArray(UBound(intArray)) = intX
End If
End If
Next intX
End Sub

Since you are preforming an action only if all tests succeed, then do the if-statement with ands. VBA doesn't short circuit the tests, (i.e. it will evaluate each test case, even if the first one returns false.) I would suggest encapsulating each test in a function that returns a Boolean to keep your code tidy.
If Test1() and _
Test2() and _
testn() THEN
add item to array
End if
Another way is to make use of a Boolean variable in your code, like this
Dim Success as Boolean
Success=True
Test 1
If Test 1 fails then
Success=false
End if
Test 2
If Test 2 fails then
Success=false
End if
.
.
.
If Success then
add item to array
End if
If the tests are expensive, you can add an inner if statement checking to see if we need to evaluate the next test like this
If Success Then
If Test n fails then
Success=false
End If
End if
