Collecting month, day, year value using drop down list and validating the date

We can collect date values from user and check the inputs for a valid date or not by using IsDate () function. Here we will give the options to the user to select month, date and year from list boxes and text box and then create a date variable using it. Then we will check the date variable and find out it is a valid date or not.

We will display a message accordingly saying correct date or not.

Here is the code below to check the user entered date value.

Dim  todo
todo=Request("todo")
if todo="submit" then
Dim month, dt, year, my_date
month=Request("month")
dt=Request("dt")
year=Request("year")
my_date=year + "/" + month + "/" + dt
if(IsDate(my_date)) then
Response.Write  month + "/" + dt + "/" + year & " is a valid date "
Else
Response.Write  month + "/" + dt + "/" + year & " is a Not a valid date "

End If
