Sub B1_OnClick

<body>
<Form Name="F1">
<P>Enter your Date of Birth: <Input type="text" Name="T1" >
<P>You were born in :<Input type="text" Name="T2" > Month
<P>You were born in :<Input type="text" Name="T3" > Year
<P> <Input Type="Button" Value="Submit" Name="B1">
</Form>
</body>
</Html>
In this above code I have a form named F1 and a subroutine B1_OnClick to handle the form when user inputs
Date of Birth in Textbox T1 and clicks the “Submit” button. The Button will automatically trigger the
Subroutine B1_OnClick.
The subroutine will convert the value stored in Textbox T1 of form F1 into date using CDate inbuilt function
then in textbox T2 it will store Month using the inbuilt function and in textbox T3 it will store Year using the
inbuilt function.
