Little Array help, checking values ect.

10 posts in this topic

So I'm not quite sure what I am doing wrong here.

 

Here is an image of what the array spits out

Now I want it so whenever the array contains a "" to change that to "Not Copied"

 

But using

 

For $i = 1 To 99
   If $TodaysList[$i][1] = "" Then
      $TodaysList[$i][1] = "Not Copied"
   EndIf
Next

 

I get

Even though nothing has changed besides I add in that IF statement. Why is it detecting the 0's as "" ?

 

Thanks!

Because 0 sometimes Returns as the Nothing

Maybe try

For $i = 1 To 99
If Not @error Then
        If Not $TodaysList[$i][1] = "0" Then
         If $TodaysList[$i][1] = "" Then
                  $TodaysList[$i][1] = "Not Copied"
         EndIf
   ElseIf Not $TodaysList[$i][1] = 0 Then
        If $TodaysList[$i][1] = "" Then
                  $TodaysList[$i][1] = "Not Copied"
         EndIf
   EndIf
Else
MsgBox(0,"Error","Some Error maybe has been apeared bla bla")
EndIf
Next

I think this with error is stupid and maybe is wrong but i don't care just remove it if u don't Need it or if it is wrong~

Not tested but I think this may work.

 

For $i = 1 To UBound($TodaysList) -1
   If StringLen($TodaysList[$i][1]) = 0 Then $TodaysList[$i][1] = "Not Copied"     
Next

wait, wait, wait. containing nothing, containing zero, and being empty are all the same?   :evil:

This has been discussed numerous times.

When you compare a number against a string, the string is converted to a number. In AutoIt if the string doesn't start with a number it is converted to 0 (zero) when compared against a string. If the string is empty it is also converted to a zero.

$string = "10"
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)
$string = "a10"
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)
$string = "0xa10"
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)
$string = "10xxxx20"
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)
$string = "0"
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)
$string = ""
ConsoleWrite("This string contains: " & $string & " and will be converted to " & Number($string) & " when compared to a number" & @CRLF)

 Should be fine.  Though I would certainly distrust the view, so depending on how the input was validated maybe

If StringLen(stringstripws($TodaysList[$i][1] , 8)) = 0
