[SOLVED] character count at runtime

Hi Sergio, This is not really pretty, but it should work:

1. In the Start Modification Trigger of the field where the user enters the SMS text set a component variable to true (e.g. $SMOD$="T"), calculate the remaining characters (e.g. vRemainingChars = 160 - $length(@$fieldname)) and execute the macro "^NEXT_FIELD" 2. In the <Next Field> trigger check if the variable (e.g. $SMOD$) has been set; if that's then reset the variable to false ($SMOD$="F") and issue a return(-1)

Instead of doing the calculation in the Start Modification Trigger you also could do it in the <Next Field> trigger (right before the return(-1)). Please note that Uniface will think that the user tries to leave the current field when the macro "^NEXT_FIELD" is executed. So please be "careful" with the code that is executed in the Validation and Leave Field Trigger - maybe you should put the code in the mentioned triggers in an if-clause that is only executed when $SMOD$="F". Just an idea. Hope this helps - and I hope that I did not forget something. Kind regards, Daniel

Thank you Daniel. It works. I hate triggers logic sometimes    Sergio.

Hi Sergio, You are welcome. And glad to hear that it works. The "wonders" of (the) Uni-verse. Daniel

• OK, we are back in the old SMOD-NFLD ping-pong.
• Please have in mind that the SMOD is activated BEFORE the entered key is processed. So you see the field contents as it is before one modified it. As a consequence, your length estimation inside of the SMOD may not be correct.
