Array usage / Empty Array / _ArrayAdd()

Recommended Posts


I am a little confused on how to best manage an array. There doesn't appear to be a way to have an empty array, that is, an array with no elements. If I try to define the array as:

Dim $Array[]    or
Dim $Array[0]
the code will not compile.

So I start out defining the array as

Dim $Array[1]
The problem with defining the array like this is that it leaves a single blank value in the array. When I use the _ArrayAdd() UDF the blank value in the array always remains and the array appears to have one more item then desired. I don't see how you can use _ArrayADD without this occuring.

What am I missing?

M23, thanks again. That clears that up.

Now, on a side note, I was a little puzzled why your linked post didn't show in my search results when I did a search of all forums for "empty array". That other forum post was titled "Declaring an empty array", you think that would show near the top of the search results. But, what I realized now is that the search results are displayed based on Last Update Time, Title(alphabetically), Number replies or Views. There doesn't appear to be anything to display the search results based on relevance. I did a google search using "empty array site:autoitscript.com/forum/" and that post was second in the list so I will use google from now on to search instead of the built in search.
