Deleting item from multidimensional array

4 posts in this topic

I am adding items to an array like this:

For $i = 0 To $rows

;Code that generates values goes here.

;Add item to array.

$FileList[$i][0] = <some value for 1st column>

$FileList[$i][1] = <some value for 2nd column>

Next

I then need to delete row 0 because it is always empty (values are 0) no matter how I try to prevent it.

I tried using _ArrayDelete($FileList, 0), but it does not work It apparently doesn't see this as an array. I am not using a listview for this.

Is there a way to delete an item in this type of array?

If you are using the current version of AutoIt, then _ArrayDelete() works fine with 2D arrays. It will only delete rows (first index), not columns (second index). If you need to delete a column, you will have to run a loop to copy higher numbered column data down and then ReDim the second index to the new size.

Oops, I forgot to mention which version I'm using. I am using 3.2.10.

I tried v3.2.12, but along with the new SciTE version to match, I was getting errors. So I went back to 3.2.10 and the previous SciTE version.

If I don't/can't use _ArrayDelete(), what other method can be used to remove a row from a multidimensional array? [no need to delete a column].

Just open the 3.2.12.1 version of Include\Array.au3 and modify that code as required to do what you want.

What kind of errors did you get migrating from 3.2.10.0 to 3.2.12.1? Other than some changes to RunAs() and the #include file structure, which is easy to fix, it shouldn't be hard to update your code.
