This is a pretty dumb question but I can't seem to find
answer.

How do you check to see if a datatype of a variable is
correct? Eg in Visual Basic:

Dim datevar
datevar= "1a/2/2004"

If IsDate(datevar) <> true then
msgbox "The value in variable 'datevar' is not a date."
End if

Thanks.

Use Typeof. For Eg

If TypeOf dateVar Is DateTime Then
'Your code
End If

Hi, Manoj. I tried your code in C# but it won't work.
Here is what I tried to do but it kept erroring out.

if typeof(txtStartDate.Text)is System.DateTime

{
this.lblStatus.Text = "Start Date must be a date value.";
return;
}

Do I have to assign txtStartDate to a variable? How would
you do it? Thanks for info.
