Keypad Entry

[xkenneth]

All,

   Is there a simple way to handle keypad entry similar to most HMI/SCADA systems? IE click on the control and the little keypad entry comes up?

Not sure if I understand correctly, but are you talking about an on screen keyboard? One way to handle would be to run the command prompt with command 'osk'. Elaborate more if I have not answered your question.

you need to give a little more info here. What are you doing. It is very possible to have a key board pop up when you click something or if you are using a touch screen ( I am assuming you are based on this question) then you can make this happen. We need to know what you are doing and how it work. If you can post your code that helps the most.

Hi, 

   I haven't written any code yet, I'm just curious as to how you'd do it. I'll be deploying my app on a generic touch screen. I'm not using the NI module.

I have done this it is not all that hard (I cant post the code since it is part of an internal company library). 

essentially on mouse down? event for a numeric, open up a modal dialog with the a cluster of buttons for the numerics and handle the logic there.  Once you have writen this one time, you can reuse it on any application.

Paul,

   Thanks, I realized this. Although I have quite a few variables and it would be nice to simply "enable" the ability in a properties dialog or something instead of handing an event structure for every one.

Thanks!

You could make an Xcontrol for this, it would be a moderate amount of work, and then make a property to allow touch screen or not.  It would be nice if this was provided for free but I havent found one.  One thing to keep in mind is that you should leave plenty of space on your touch screen application since the screen is less accurate than the mouse.  good luck.
