Hi,
if you are programming Visual Basic you can use the following function:


' Returns True if inpDate as string representation of date like
' 16/jan/2004 is a valid date.
Public Function DateIsValid(inpDate As String) As Boolean
    On Error GoTo Err_Handling_DateIsValid

    Dim testVar As Date
   
    DateIsValid = True
    testVar = CDate(inpDate)

    Exit Function
Err_Handling_DateIsValid:
    If Err.Number = 13 Then
        DateIsValid = False
    End If
End Function

hi,

How about making a switch to DateTimePicker control. You can custom the control to dd/mmm/yy format.

best would be to use a masked edit box it takes care of this validation by the format

Hi Bhagyesh Trivedi,

Thnx for ur suggestions...

Masked edit box takes care only of the format but does not validate the entry. For example if i give the mask as ##/???/## It does take care of te format but if i enter 99/kkk/88 , then it only validates the format and not the text. i want to also validate the text as month cannot be kkk or date cannot be  99 etc.

any ideas ......


Regards

In that case, why don't you consider using DateTimePicker control. You can custom the control to dd/mmm/yy format and no validation has to be done.
It appears in the form of combo box but when you drop down. it is actually a calendar.

Hi  FarzadA,

Ur function is good but it doesn't validate for the date part. for exapmle if i give 44/jan/02 it returns true.

Because 44/jan/02 means 2-Jan-1944. If you use 44/jan/2002 it returns false.
Is year is right most digits? Or input date is ##/###/## format? I can modify this function.

' Returns True if inpDate as string representation of date like
' 16/jan/04 is a valid date. Only workd with dd/mmm/yy format.
Public Function DateIsValid(inpDate As String) As Boolean
    On Error GoTo Err_Handling_DateIsValid

    Dim testVar As Date
    inpDate = Left(inpDate, Len(inpDate) - 2) & "20" & Right(inpDate, 2)
    DateIsValid = True
    testVar = CDate(inpDate)

    Exit Function
Err_Handling_DateIsValid:
    If Err.Number = 13 Then
        DateIsValid = False
    End If
End Function
