Converting DBL control to control string of different format

[tareyes]

In the below control, the "Channels" control is an input of double and the "Task Channels" is an input of string and also in a different format to communicate with the VIs I'm using. I am trying to eliminate having two separate controls for this input as they are linearly related besides a formatting issue. Is there a way to convert it in the following format below:

DBL     STRING

   4    =     0:3

   3    =     0:2

   2    =     0:1

   1    =      0

The part that seems like it might be complicated with what I am doing is that a value of 1 eliminates the colon and second digit.

Thank you for any help.

A simple lookup table would probably be the easiest.  You have an array of the string values and you use Index Array with the Channels value as the index.

Try this

(note, you probably want to handle the case where the user passes a "0" to the Channels input)

Appreciate the help, this is perfect for my input condition. In response to the control for a "0" input, it is not necessary because the VI for the DAC I'm using will throw an error with no channels selected and fail to run anyway.
