| How to check if a string variable has nothing? |

| Headcrab Zombie:
Interesting, didn't know that. |
| Reinforcements:
So, is "$=" for string comparison and "==" for number comparison? What would be the one if a string isn't equal to another. Something like this perhaps? --- Code: ---if(%theString $! "") { <code> } --- End code --- |
| Headcrab Zombie:
!$= |

If it's a string, you have to use $= "" if you just use == 0 it will always be true because trying to convert a string to a number will always be 0 --- End quote --- --- Quote from: Headcrab Zombie on September 14, 2010, 12:06:15 PM ---!$= --- End quote --- Thanks |
| Red_Guy:
I use: if (%str $= "") or if (strlen(%str) == 0) both work to check if a string contains nothing. |
