Variable based arrays? Less limitations?

Recommended Posts

I was checking out the technical limitations of Autoit recently and I noticed there are restrictions on the number of dimensions as well as the elements themselves. However there is no limitations on the numbers of variables that can be used in a script. I have been pondering the possibility of creating a UDF for myself that would mean I could use variables to perform the same actions as I would use arrays for.

What do you think about this? Are there any pro's or con's that you can think of? Array dimensions are separated by [ and ], I could separate dimensions with _ and _ and use assign to create the appropriately names variable-array and add the needed numbers at the end in a For loop and use 0 to always list the number of total elements.

What are your thoughts? It is just an idea but after seeing the limitations of arrays it just got me wondering.

after seeing the limitations of arrays

AutoIt arrays are limited to 64 dimensions and a total of 16,777,216 elements. What on earth are you thinking of coding which uses anywhere near that number of dimensions or elements? :wacko:

Open spoiler to see my UDFs:


ArrayMultiColSort ---- Sort arrays on multiple columns
ChooseFileFolder ---- Single and multiple selections from specified path treeview listing
Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
Toast -------------- Small GUIs which pop out of the notification area

As a sidenote, max practical array dimension in AutoIt is 24. 64 is only a theoritical limit which you can't reach.

$aTest[2][2]...[2] reaches the maximum number of elements limit (224 = 16777216) when the dimension is 24, and [2] is the least meaningful individual dimension value.

BTW, if ever you really need more than 16777216 "variables", I bet my ass you badly need a database to store and organize your data, i.e. a perfect job for SQLite which comes with standard AutoIt installation.
