>>Nadya,

>>You're welcome

>>What I wanted to say is that this is a rather quick way to enter one hour = 4 keystrokes: 1 0 0 ENTER
>>
>>Should you have two textboxes, you would enter 3 keystrokes : 1 ENTER ENTER
>>
>>In case of working with spinners (1) manual: 3 keystrokes, (2) with the mouse takes more time
>>
>>1:15
>> with one textbox = 4 keystrokes: 1 1 5 ENTER
>> with 2 textboxes = 5 keystrokes: 1 ENTER 1 5 ENTER
>>
>>
>>Using two controls makes it more difficult to store hhmm in one table field
>>
>>So, I find one textbox better. On occasions you'll have a keystroke too many
>>
>>In the supermarket (cash register) they never enter the decimal point.
>>One dollar is 1 0 0 (or 1 00)
>>$1.50 is 1 5 0
>>
>>In this case you never enter the colon, but you have to explain to the textbox where the colon should be - like the cash register - you never enter the colon [ or with two textboxes an ENTER or TAB ] and on occasions you have to enter a zero too many. But hey, you never enter the colon [ or decimal point ]

>Good points. In case of multiple textboxes I guess we need a container based class which would allow to save value in a field using container's LostFocus (I guess). I also need a way to display correct value. And finally, in my table I store duration in minutes, so I would need to convert hh:mm to mm.

If your store hhmm and you know it, then the minutes become int(hhmm/100) * 60 + mod(hhmm,100)
[ or use a view ]

You can convert it to minutes - by the control or by the record rule. You could then have another control to display the minutes in hh:mm by simply change the controlsource
[ or use a view ]

>Anyway, for now I put the problem aside and working on something else right now. It's also a good idea to go out and take some lunch...

Keep me posted after you have found the other classes
