 Posted: Fri Jun 15, 2007 10:56 pm Post subject: How come this if statement is true? |
 |
|
| Code: |
a = 1
b = 2
c = 3
if ((a = 1 and b = 3) or c = 3)
{
msgbox, true
}
|
The paranthesis do nothing?
How should I think when making if-statements with several "or/and" without using paranthesis? Should I avoid it?
Best Regards |

| it's true b/c variable 'c' does equal 3.....if (a and b) OR c....c is true, therefore, statement is true. If c is true, then a and b are irrelevant...if c is a and b are true, then c is irrelevant. |

Oops. Thanks mwharri! Mistakes like that can be very hard to detect yourself sometimes. Now I understand. The paranthesis does work!  |

Although I'm a little confuded at some of the and/ or parts, such as:
| Code: | IfWinExist, Calculator and WinNotExist, Notepad
{
...
} |
I know thats junk, but what should it be when writing and/or with winexist/notexist? |

use the function form of WinExist()
| Code: |
If WinExist("Notepad")=0 and WinExist("Calculator")!=0
{
}
