I'm sure this is insanely obvious... but i can't figure it out.
I have a db that organises applications for an event. Included in the
applicant information is their date of birth. On a form or report i can
calculate and display their current age (=(DateDiff("d" ,[DOB],Date()))/365)
and also their age at the time (=(DateDiff("d" ,[DOB],"28/07/07"))/365) of
the event.
As you can see i'm using a hardcoded date for the event date so i have to
change the expression all over the place. How can i set this date in one
location and reference it throughout the application?
cheers,
/mark 6 1475
Mark,
You could calculate theese ages in a query and use it as a source for forms
and/or reports.

Hello Mark,
I tried following :
a) create a module where I create following constant :
Public Const cEventDate As Date = "28/07/07"
b) create a testform with following code in its on-open event :
Private Sub Form_Open(Cance l As Integer)
MsgBox (DateDiff("d", "28/09/06", cEventDate))
End Sub
Conclusion : result was correct and I only need to change the value of
the constant
whenever there's a new event date.
Hope this works for you...
Regards,
Rudi.
Rudi,
Right, but in order to use that constant in reports, you'd have to have
a public function:
Public Function fEventDate() as Date
fEventDate = cEventDate
End Function
Then, you could use
=(DateDiff("d",[DOB],fEventDate()/365)

If it's important that the age be accurate to the day then I'd suggest
Googling this group for an accurate Age function. It's surprising how much
ill will can be generated by being a day or two out.
If on 28/Jul/07 you use your function to tell a woman born on 30/Jul/1977
that she's over thirty, then you may need to take steps to avoid a problem.
Big, fast steps.

Chris,
thanks for pointing that out. I was too hasty, but then again,
according to Alan's justified remark I might have reason enough to! :-)
Thanks guys.
Rudi.
So... why when i create a form... have a text box can't i set the value of
that text box...
where do i put the expression =(DateDiff("d",[DOB],cEventDate()/365))?
Control Source??

Does anyone please know of a way to access static methods of a class, when
the name of that class is held in a variable?
I have several classes (PHP5) which all have identically named methods and
members.
I want to pass the name of one of the classes to an included file which
does some standard operations using those methods and members. (So several
different programs can include that file, each passing a different class
name.)

is there a way to access a static member of a class, if the classname

this does not work:

for methods there is a solution:

Hello,
Can anyone please advise me how to retrieve the value of a constant at runtime, given only its name (in a String).
I have experimented with the Microsoft.VisualBasic.Interaction.CallByName() method, but without success.
Alternatively, can you suggest how to import string constants for use as control property values; something along the followng lines ...

This seems like it should be so simple, but I'm just not having much
luck with this. I have an constant in my App.xaml.cs file (i.e., code-
behind) called Name.
public const string Name = "Dan";
And now, I want a Label on my Window1.xaml page that shows the Name. I
will eventually want to show the same Name on other pages. So, I want
to be able to access (bind to?) this global constant from anywhere in
the project.

The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
