I'm Stumped!

[Triton 0]

I'm getting an error in this code, I get this error on the second removal of a item. Any sugestions would be helpful.

If guiread()= $nAdd Then

If $m=1 Then

guisetcontroldata($softlist,guiread($mylist))

$software[1] = guiread($mylist)

$m=2

else

$n=$n+1

guisetcontroldata($softlist,guiread($mylist))

$software[$n] = guiread($mylist)

Endif

EndIf

if guiread()= $nRemove Then

If guiread($softlist) <> "" Then

$i=1

While $i <= $n

If $software[$i] = guiread($softlist) then

msgbox(0,"",$software[$i] & "=" & guiread($softlist))

Else

$list = $list & "|" & $software[$i]

msgbox(0,"","z=" & $z & " " & "i=" & $i)

$soft[$z]=$software[$i] <----------------------- Error

$z=$z+1

EndIf

$i=$i+1

Wend

$n=$n-1

$software = 0

$software = $soft

$soft = 0

$x=1

While $x <= $n

msgbox(0,"Software Array",$software[$x])

$x=$x+1

Wend

If $n = 0 Then

guisetcontroldata($softlist,"")

Else

guisetcontroldata($softlist,"")

guisetcontroldata($softlist,$list)

endif

endif

endIf

Off the top of my head, you're probably indexing out of bounds because you are going from 1 to $n instead of 0 to $n-1 which is the correct range for your array.

Allright, I think I am confused!

To Initialize an array is something like this = Dim $temp[10]

This creates an array structure with ten indexes starting at 0 through 9

Soooo I can now have data in index 0 , 1 , 2, 3, 4, and so on.

Now, how do I retreive the data properly in a for loop ?

:iamstupid:

[CyberSlug 3]

Dim $temp[10]

; Code to populate (initialize) array goes here

; Prints out the data
For $i = 0 To UBound($temp)-1
   MsgBox(0,"", "Element " & $i & " is " &  $temp[$i])
Next

P.S. You can also use StringSplit to easily create and initialize an array.

$temp = StringSplit("Jan,Feb,Mar,Apr,May,June,July,Aug,Sept,Oct,Nov,Dec")

Note that if you use StringSplit, that index 0 contains a special value.....

Dim $temp[10]

; Code to populate (initialize) array goes here

; Prints out the data
For $i = 0 To UBound($temp)-1
  MsgBox(0,"", "Element " & $i & " is " &  $temp[$i])
Next

oK Say I want to remove the data that is in $temp[4] and re-initialize the array with just 9 elements?

Haven't we been over this before or am I thinking of somebody else? Array's are statically allocated. You can't delete an element out of the middle and have the rest "drop down". In the future, there will probably be a ReDim function which can be used to resize an array, but I doubt it will allow you to arbitrarily select which elements get truncated when going to a smaller size. In fact, writing a single-dimensional redim function is quite easy to do and several people have posted code to do so at various points.

If you MUST have a way to delete a random element from an array and have the rest drop down, it should be trivial to implement a function to do so.

But I must admit, I don't know why you would want to do such a thing. I guess I'm just used to arrays in C/C++ where the ability to just delete a random element from an array would pretty much kill the program as pointers begin to reference invalid places.
