Mask when inputting data

[Treble20]

Hi, I`m having a brain freeze and need some help.

I need to create an input mask on a text box so that when someone enters a serial number they can only input nnnn-nn-nn where n is equal to a number. I have wrote a quick vi that checks that only a number is being entered and not characters but i want to add the "-" after the first 4 numbers have been entered and again after the next two numbers have been entered.

Any help would gratefully recieved.

Cheers

Have a look at this thread at LAVA.

I posted an example that does exactly what you want.

This may also be a solution. It is in god windows style and look profesional

Personally, I would make the control an indicator and fill the numbers into a U8 array of size=8 according to "mouse down" events. The dashes can be added programmatically whenever the string display is updated. Pressing backspace would delete the latest element by editing the array.

Here is a very crude example (LV8.5) that shows the main idea.

(The insert cursor is irrelevant here and a bit distracting. To hide it, you could disable the control and use FP mouse down events. To see if you are over the control, add a boolean state in another shift register and switch it according to mouse enter/mouse leave.)

Sorry, of course I meant "key down" events as will be obvious from the code picture. 😄
