why doesn't c# seem to support some kind of 'null date'
for instance:
i have an application where the user is not obliged to enter a date until
an event happens (e.g. a bug was fixed on xyz)
the calendar control in asp.net doesn't seem to have a selectedDate = null
property

I'm using the Microsoft Enterprise Data Access block to call the stored
procedure. One of the values the stored procedure returns is the stop date.
When the stop date is null, the program crashes. I would like to be able to
test for a null date, and then store the mindate value in the class
property.
I've tried the following, but it still crashes.
if (dbCommandWrapper.GetParameterValue("@StopDt") == null)

I am looking for the "right" way to handle inserting and presenting null
date values.
Public Const c_NullDate As Date = #12:00:00 AM#
If I set the value of a date variable in an SQL Server insert statement to
c_NullDate, the insert statement works. When I re-read the row and display
the inserted date value in a text box, the string "1/1/1900" is displayed.
If one wanted the textbox to display an empty string, how should either the

Is there a function to set a null date in vb.net? Normally, I create a
const NULLDATE = "1/1/1900", but that becomes a drag at times. Especially,
handling a nulldate from SQL into a dataset.
Thank you,

If I need to assign a NULL value to a date variable, how would I go about
doing that? For right now I am using 01-01-2001, however I don't want to use
a "real" date if the date should really be NULL.
Thanks for the information.

When I pass a null date from my client to my service project, it comes
across as #12:00:00 AM#. While I can easily code for this, it seems like a
hack. Is this normal?
I'm using WCF, by the way.
Thanks,
Ron

Good afternoon,
I am currently working on this unbounded form that has numerous date fields. I wanted to know if it is possible to save data in a form, with a null date field. I am currently getting an error, and would like to know if there is a way around it. I am doing this feature just in case users do not need to enter a date for a specific record.
Also, when the form is loaded all the controls (checkbox, combobox, listbox, and...

Hi Everyone,
There are so many Nullable DateTimePickers out there that this post may not even be found among all the others, but I wanted to try. First, I want to thank all the authors of the code I used as a starting point. Second, I hope this code helps someone as much as they helped me.
I have built a Nullable DateTimePicker and NullableCalendarColumn/Cell/EditingControl that is nearly 100% complete, as far as I can tell. There is...
