[Year 12 SofDev] Date calculations

[Don Morelli Optus]

The problem with your condition is that you are not comparing the right data
types. Convert each to a date, using the Cdate() function (covert to a date
datatype), and then compare the results, like below

 

If CDate(txtDate.Text) < CDate("1/7/09") Then ....

It will work fine as I tried it.

Can anyone help me with VB6 code for the following task. My students are
working on a program which will allow a discount on goods purchased before
30th June 2009. I have tried the following line of code:
 
 if val(txtDate.text) < #1/7/09# then   
etc. etc
 
However this gives a discount to dates before and after the cut off date.  I
have also tried declaring orderdate as a variable of type date and also
changing 'val' to 'dateval' in the above code but this then gives no
discount at all regardless of the date. I thought this would be simple to
code but am tearing my hair out. Thanks in advance to anyone who can help.
