I have a variable in my application of type Varchar where I only get hours in it. However, I wanted to format the mask ":" in it, after the hour and before the minute, when putting in the Picture property the value: 99:99, when opening the screen appears the ":", but when typing any value in the format field do not stay.
Ex: if I type 0842, it was to format by itself 08:42 but it is not formatting. Can anyone tell me what it can be?
