create multiple variables with a while loop

[mcclane654]

Local $counter = 0
While $counter < 5
    $var$counter = 1+$counter
    $counter=$counter+1
WEnd

GUICreate("test")
GUISetState()
GUICtrlCreateLabel($var0, 5, 20)
GUICtrlCreateLabel($var1, 5, 40)
GUICtrlCreateLabel($var2, 5, 60)
GUICtrlCreateLabel($var3, 5, 80)
GUICtrlCreateLabel($var4, 5, 100)

i would like my $var to have the counter number added to its name. is this even possible if it is how?

Using arrays makes it much easier than adding the index to the variable name.

Means: Use $var[0] instead of $var0.

yes of course (facepalm)

thx water

Does this help at all?

Local $var[1], $counter = 0
While $counter < 5
    $var[$counter] = 1 + $counter
    $counter = $counter + 1
    ReDim $var[UBound($var) + 1]
WEnd

GUICreate("test")
GUISetState(@SW_SHOW)
For $i = 0 To $counter
    GUICtrlCreateLabel($var[$i], 5, 20 * $i)
Next

Maybe Im wrong, but i think changing an array size inside a loop is a not a good thing.

Instead it should create at start an array with the final size. If the amount of elements that will be assigned to the array is unknow before run the program, then you should use a guess value for the array size and after the loop use the ReDim to reduce the array size.

In this case the final size is know, so the code could be:

$max = 5
Local $var[$max], $counter = 0
While $counter < $max
    $var[$counter] = 1 + $counter
    $counter += 1
WEnd

GUICreate("test")
GUISetState(@SW_SHOW)
For $i = 0 To $counter-1
   GUICtrlCreateLabel($var[$i], 5, 20 * $i)
Next
 
sleep(3000) ;Time to see the GUI before the program end

If the amount of elements that will be assigned to the array is unknow before run the program, then you should use a guess value for the array size and after the loop use the ReDim to reduce the array size.

This "guessing" the size of an unknown array could cause for a "Array variable has incorrect number of subscripts or subscript dimension range exceeded" error and that could lead to it not working at all.  There is nothing wrong with re-sizing an array within a loop.  If there is a known amount then you could set the size at the beginning and not use another variable as follows:

Local $var[6], $counter = 0
While $counter < UBound($var) - 1
    $var[$counter] = 1 + $counter
    $counter += 1
WEnd

GUICreate("test")
GUISetState(@SW_SHOW)
For $i = 0 To $counter
    GUICtrlCreateLabel($var[$i], 5, 20 * $i)
Next

Is there a way to create directly the name of the variables in loop ? like something like that "dim $p$i" where $i increase each time ?

That's what arrays are being made for.
