Just get the keyascii value of the keys that you pressed under the keypress event of the textbox then restrict the textbox that the first character must not accept numeric values.

Or you can use maskededit box to solve this problem

but i need a code

Char = Chr(KeyAscii)
KeyAscii = Asc(UCase(Char) )

p501 = "CM01234567 89" + Chr$(127) + Chr$(8)
If InStr(p501, Chr$(KeyAscii)) = 0 Then
KeyAscii = 0

subtract time

i want to subtract time


Private Sub Timer1_Timer() Start Time
label1.Caption = Format(Time)
End Sub

Private Sub Timer2_Timer() End time
label2.Caption = Format(Time)
End Sub

how to subtract (End time - Start Time)

ex. 12:15:40 - 10:15:30 = 02:00:10
End time Start Time ??????

you need to use DATEDIFF function .

DateDiff(interv al, date1, date2[, firstdayofweek[, firstweekofyear]])
Where interval will be in string as
yyyy Year
q Quarter
m Month
y Day of year
d Day
w Weekday
ww Week
h Hour
n Minute
s Second
It will return difference of two dates as long according to parameters provided.
