Data Entry Text Box

[eoin87]

Hi guys,

I have some data entry boxes in my GUI which I would like to control.

The data is entered in Hex format ie. Ox sits next to the text entry box and the user should enter a value between 00 and FF for one byte.

As soon as the user tries to enter R for example I would like for a warning sound to occur and for the R not to be accepted by the text entry box, I would also like to limit the size to one byte, ie someone can't enter FFF.

Any help greatly appreciated.

Sorry I forgot to add one more question.

I would also like for the hex address to be incremented by 1 when the user touches the Up key and decremented when the Down key is pressed  of course the user will have to click on this box beforehand.

Use a numeric control.  Change the properties to:

Appearance: Show Radix

Datatype: U8

Display Format: Hexadecimal.
