 Posted: Tue Apr 01, 2008 4:53 pm Post subject: If var [not] in false match |
 |
|
| Code: | a := 20
b := 30
c := ""
d := ""
Var := 30
If Var not in %a%,%b%,%c%,%d%
MsgBox, Should not match here
Else
MsgBox, It is in it though! |
The "expression" says:
| Code: | | If 30 not in 20,30,, |
however 30 is in it, but we get in the above code that it is not, just because we are matching with 2 blank variables.
If we change it to:
| Code: | | If Var not in %a%,%b%,%c% |
it will work fine. This is not expected behaviour as 30 is never contained in [blank] ?? |

I believe this is interpreting the list as such
20
30,
therefore 30 doesnt exist, but 30, does

Interesting thought. That seems quite likely. However, I dont think it should do this. It should only do that for `, not ,
It becomes very annoying using if [not] in as then you have to check all the variables are not empty, which defeats the purpose of using it (to save lines) |

for some reason this works different with commas.
| Quote: | | Two consecutive commas results in a single literal comma. For example, the following would produce a single literal comma at the end of string1: If Var In string1,,,string2. Similarly, the following list contains only a single item with a literal comma inside it: If Var In single,,item. To include a blank item in the list, make the first character a comma as in this example: If Var In ,string1,string2 (when using the "contains" operator, a blank item will always result in a match since the empty string is found in all strings). |
