Best practice for 'if' statements that exceed the 10 line continuation limit in Visual Basic 6.0

Example:
If condition or _
condition or _
condition or _
condition or _
condition or _
condition or _
condition or _
condition or _
condition or _
condition or Then
Do something
End If
Say I have more than these 10 conditions I need to evaluate... Is there a better way than just nesting multiple sets of these if
statements?
Soluzione
Here's an option -- do one test at a time, tracking the final result in a boolean. When you're all done, just test the boolean.
Dim A As Long
Dim B As Long
Dim C As Long
Dim D As Long
Dim Result As Boolean
Result = True
Result = Result And (A > 10)
Result = Result And (B > 10)
Result = Result And (C > 10)
Result = Result And (D > 10)
If Result Then
' Do "something" here...
End If
If any of A, B, C, or D is less than 10, Result
will flip to False
and stay that way from then on. It will only be True
if all of the tests pass.

You could use Case statements. It's a little bit cleaner than if
s: http://msdn.microsoft.com/en-us/library/cy37t14y%28v=vs.80%29.aspx
Dim Result as boolean
result = false
If condition1 Then result = true
ElseIf condition2 Then result = true
ElseIf condition3 Then result = true
ElseIf condition4 Then result = true
If result Then debug.print "Success"
If you wanted to use a select statement where conditions are not the same then use:
Select Case True
Case A=5,b=10,c="my answer",d=11
....
End Select
