Get item from array Topic is solved

[Wigi]

Hello all,

I hope this is an easy question.

I am looping over an array:

Code: Select all

                StringSplit, ParamArray, sText, `n
                Loop, %ParamArray0%
                {
                }

Let's say the array contains 30 elements. I need to loop from 1 to 10,
and each time I need to store 3 variables:
- the value in the array at position x
- the value in the array at position x+10
- the value in the array at position x+20

So, there are 3 parts in the array: 1 to 10, 11 to 20, 21 to 30. They need to come by in groups of 3: 1, 11, 21, then 2, 12, 22, then 3, 13, 23, ...

How can I code this please ?
None of the syntaxes I tried seems to work.
I use A_index, but then referring to A_Index + 10, A_Index + 20 seems impossible.

That's one reason array objects are better than pseudo arrays, which you can do by using StrSlit() instead of StringSplit. But you can still do it. Try using an intermediate variable:

Index10 := A_Index + 10
Index20 := A_Index + 20

Then you can refer to ParamArray%Index10% and ParamArray%Index20%.

Thanks, I will implement it and see if I can get it working.

Strange but it seems to be here that I am having a difficulty.
This works:

Code: Select all

                    Index_type := A_Index + 10
                    Index_default := A_Index + 20

but this does not work:

Code: Select all

                    Index_type := A_Index + ( Nr_of_params * 1 ) + 1
                    Index_default := A_Index + ( Nr_of_params * 2 ) + 2

Do I need to do a conversion ? In the second case, I get numbers like 16.000000 instead of 16

That 10 and 20 in my example were simplifications, now I am working with an offset that depends on the number of items in the array.

Thank you.

Your variable Nr_of_params must be a floating point value. Try this:

Code: Select all

                    Index_type := A_Index + ( floor(Nr_of_params) * 1 ) + 1
                    Index_default := A_Index + ( floor(Nr_of_params) * 2 ) + 2

Thanks. It’s well after midnight here, I will check it out tomorrow.

It works with Floor ! Many thanks boiler.
