Re: pointers to arrays

Hi Kirk Yes all the arrays are Text Arrays. My aim is to import all the data and load it into the various arrays. The basic problem is that I dont know in advance, how much data there will be. Think of it like this. There maybe beween 1 and lets say 16 audio channels. each audio channel maybe

Re: pointers to arrays

Peter, This is easy to do with local arrays and dynamic variables. It looks like you only need to build text arrays. You can declare a local array, ARRAY TEXT($aText2d;0;0). Then you can resize this to add more 'columns' as needed and populate them. Next you need to populate the listbox. First

Re: pointers to arrays

OK thanks There will be a maximum of 16 passes through the loop, with a maximum of 14 arrays declared on each pass. each array could have between 1 and a couple of hundred elements. it depends on the size of the original document, from where all the original data is imported. each one of the 14

Re: pointers to arrays

Peter, IF your code will never be compiled the first code I sent will work, and you will be creating arrays 'on the fly', if you do this, I suggest you create local arrays, array names starting with a '$', so that they are thrown away at the end of the process/method. IF you code will EVER be

Re: pointers to arrays

compiler declaration(s) Array (Variable_Name;Size) is the type of the array you want, text, longint, etc On Tue, 31 Oct 2017 19:42:42 +, Peter Mew via 4D_Tech wrote: > Thank You > And How do I create the Arrays in the First Place > -pm > > On Tue, Oct 31, 2017 at 7:32 PM, npdennis

Re: pointers to arrays

some pseudo code to follow: an out line would be: if the code is not compiled the following will work, if it is (or is going to be) then you need to create the arrays before hand. For the example all arrays are text. Array pointer($New_Array_Handles;0) For ($i;1;$Number_Of_Arrays)

Re: pointers to arrays

> but that doesnt work, hence my question If you want to run compiled you will need to use a list box to create dynamic arrays… or declare every possible combination you will use in a method and use get pointer… However in your case you might be able to use a 2D array, or depending on what

Re: pointers to arrays (and List Box Basics)

A past discussion mentioned creating arrays on the fly using a Listbox command that creates columns. This is for an array listbox. http://livedoc.4d.com/4D-Language-Reference-16.2/List-Box/LISTBOX-INSERT-COLUMN.301-3433513.en.html C_POINTER($NilPtr) LISTBOX INSERT

Re: pointers to arrays

OK If I read that correctly, that will create the arrays for pass 1 through the loop, but what about creating the arrays for pass 2, and any subsequent passes. I expected to create the arrays, as they were needed, for each pass. something like For ($i;1;Size of array(EDLBlockArray)) If ($i<10)

Re: pointers to arrays

> And How do I create the Arrays in the First Place If you are running compiled you I think will need to type the arrays in a method someplace so the compiler knows about the arrays. I know that some variable types don’t need compiler declarations, but I think arrays do. // Some method maybe a

Re: pointers to arrays

> Im pretty sure I need to use pointers to accomplish this, but I dont know how. Try the command Get Pointer… $p:=Get Pointer(“Array201”) or $x:=201 $p:=Get Pointer(“Array”+string($x)) However compiled you may need to have the arrays declared some place. Neil

pointers to arrays

Hi I want to achieve the following: To Loop through a block of code (the number of times will be determined elsewhere, but may well be different each time). Create a set of arrays that will have the same name + the loop counter, for each pass through the loop So pass 1 might create 3 arrays called
