Question about If...Then expressions

7 posts in this topic

If $ZahlenArray[3][1] = $ZahlenArray[4][1] = $ZahlenArray[2][2] = $ZahlenArray[3][2] = $ZahlenArray[4][2] = $ZahlenArray[3][3] = $ZahlenArray[4][3] = $ZahlenArray[3][4] = $ZahlenArray[4][4] = $ZahlenArray[3][5] = $ZahlenArray[4][5] = $ZahlenArray[3][6] = $ZahlenArray[4][6] = $ZahlenArray[2][7] = $ZahlenArray[3][7] = $ZahlenArray[4][7] = $ZahlenArray[5][7] = "1" And $ZahlenArray[1][1] = $ZahlenArray[2][1] = $ZahlenArray[5][1] = $ZahlenArray[4][2] = $ZahlenArray[3][2] = $ZahlenArray[4][3] = $ZahlenArray[3][3] = $ZahlenArray[4][3] = $ZahlenArray[3][4] = $ZahlenArray[4][4] = $ZahlenArray[3][4] = $ZahlenArray[4][5] = $ZahlenArray[3][5] = $ZahlenArray[4][5] = $ZahlenArray[3][6] = $ZahlenArray[4][6] = $ZahlenArray[3][6] = $ZahlenArray[4][7] = $ZahlenArray[3][7] = $ZahlenArray[4][7] = "0" Then MsgBox(1,"test","1")

When the array is filled with "1"´s i get a msgbox, also if the array is filled with "0"´s i get a msgbox. I want the statement to be executed if the first bunch of array elements are "1" and the others are "0".

Could somebody please explain to me, what im doing wrong there?

There is no such construct as chained comparison tests in AutoIt language.

Hence, your statement evaluates like:

If (((((((((($ZahlenArray[3][1] = $ZahlenArray[4][1]) = $ZahlenArray[2][2]) ...

the first parenthesis results in a boolean, which you compare to a plain value, etc.

Rewrite your test from scratch!

Local $val = "1" ;; BTW, do you mean "1" or simply 1 ???

If $ZahlenArray[3][1] = $val And $ZahlenArray[4][1] = $val And $ZahlenArray[2][2] = $val And ...

I meant "1", but it would be no problem to change that to 1.

Thanks for the quick and very good answer.

If $string1 == $string2 Then ...

does the same as:

If ($string1 == $string2) = 1 Then ...

Did i understand that right?

Lookup the help file at Language Reference >> Datatypes.

Technically, (expr1 <comparison operator> expr2) gives a boolean result in {False, True}. Then that result can be converted to some other type. Conversion to integer yields the result you expect (True --> 1) but conversion to a string will probably disappoint you: True --> "True" and that string will convert to 0 in a comparison against an integer.

That's why it's much safer to use the first form

If $string1 == $string2 Then ...

than the second one.

Then don't forget that == means a case-sensitive, locale-insensitive, binary-wise comparison between strings.

If (int(string(1 = 1) = "True") = 1) Then ...

Does not make any Sense and should be avoided, but the Expression is allways True.

Did i get i now?

p.s.: What does locale-insensitive mean? Is it about the scope in which they were created?

Correct but keep away from such constructs.

No that means locale (regional) settings (string collation a.s.o.).
