Can I use Textblock within a for next?

JGoode — Tue, 11 Jan 2022 17:17:08 GMT

I have an array that I need to output but I need to be able to control the width of each line it outputs. I understand that you cannot have a duplicated textblock name but is there a way around this? I can almost achieve what I need with a basic text2 line but defining the width is important.

Any help is much appreciated.

Many thanks

You need to have a number that adds 1 each next, then convert it to a string and make it part of the name, thus your name increases/changes each time.

I used to simple text, not textblocks. Though i guess you can use this method with textblock too.

dim arr[iElement] ! for example it's an array you need to display ! i consider that each element in array is a string value (word) ! according to define text style, text has height stored in value 'textSize' maxLength = 0.200 ! for ex. maximum lenght of row is 200 mm rowLength = 0 for i=1 to iElement iLength = stw( arr[iElement] )*0.001*GLOB_SCALE rowLength = rowLength + iLength if rowLength > maxLength then add2 0, -textSize*GLOB_SCALE ! 'making' new line of text rowLength = iLength endif text2 0,0, arr[iElement] ! displaying current value of array next i

In that case text will form uneven rows (different length).
