Stripping Blank Elements ...

[jaberwacky]

Hi, me again...

If I had an array like this: http://content.imagesocket.com/images/ArrayDisplay388.jpg

Could I make another array that would only include the numbers?

Did I explain thoroughly?

I, perhaps other have the imagesocket.com URL blocked, could you post relevant code?

Yes you can make it all numbers. Look up _arraydelete and _isnumber in the help file. That should get you on the right track.

Hey, sounds good. I'll give a try and report back.

Ok, as soon as I added _ArrayDelete() into my code it throws this error message: "Array variable has incorrect number of subscripts or subscript dimension range exceeded." I ran the array through isArray() which reports that it is an array!

If isArray( $initialArray ) Then msgBox( 0 , "" , "array" )

For $i = 0 to 31 Step 1
     If $initialArray[ $i ] = 99 Then
          _arrayDelete( $initialArray , $i )
     EndIf
Next

When you perform the _ArrayDelete(), the array will have one "record" less, but you are not adapting $i.

To avoid this problem you need to process your array in the reverse direction:

If isArray( $initialArray ) Then msgBox( 0 , "" , "array" )

For $i = 31 to 0 Step -1
     If $initialArray[ $i ] = 99 Then
          _arrayDelete( $initialArray , $i )
     EndIf
Next

Hmmm Jos I never thought of doing it that way. Also wouldn't it make it quicker if you added a $i -= 1 so that it doesn't read the same item twice?

Edit: I always put a $i -= 1 in there so it doesn't skip an item and have if @error then exitloop

It just now occurred to me!

This is the idea I had to deal with the problem:

For $i = 0 to UBound( $initialArray ) - 1 Step 1
     If $initialArray[ $i ] = 0 Then _ArrayDelete( $initialArray , $i )
Next

I'm going to try it now...

"there are many roads leading to Rome" but in general you would use:

For $i = 0 to Ubound($initialArray)-1

or

For $i = 0 to Ubound($initialArray[0])

Using this would always trigger the error as the For values are only initially set. That is why I normally go for the reverse approach.

I thought the saying was all roads lead to Rome? I prefer "There's more then one way to skin a cat"

[jaberwacky]

I tried the UBound() method.

Then I tried:

For $i = 31 to 0 Step 1
     If $initialArray[ $i ] = 0 Then
          _ArrayDelete( $initialArray , $i )
     EndIf
Next

That stopped the error message but doesn't delete the elements from the array!

You stepping the wrong way. 31 + 1 continued will never = 0.

Giggity Giggity! I just now realized it and that fixed the prob!!! Thanks to all posters for taking the time! =D

This particular saying has 2 versions:

1. Alle wegen leiden naar Rome

2. Vele wegen leiden naar Rome

Translated 1. is your version and 2. is mine.

.. and we never skin cats overhere.
