Howdy All!
How can you tell the type of an object?
I am not talking about using "typeof" ..
I am talking about being able to determine if an object is a Date or String
....
Thanks for any advice!

I have a text box on a form “txtExamDate” that I know contains nothing. I am
trying to test code that will determine the text box is nothing. I am
getting the error because there is no value in the field and I am assigning
it to a date field. My question is: How do I get the If statement to work?

apparently references of type Date can not assume the value Nothing, because
the following code fails:
Dim d As Date
.......other code......
If d Is Nothing Then
End If
so then what is the equivalent to Nothing for a reference of type Date ?

Hi!
I have a little problem with the registry function. The function is
supposed to check the registry as the main form is activated. If there
is a key it should not write to the registry, as it does.
Can anybody see what I'm doing wrong?
Private Sub WriteToRegistry()
Dim regKey As RegistryKey = Nothing

is a read-only property rather than a constant. To...

Does anyone have any coding rules they follow when doing argument checking?
When arguments fail during check, do you return from the call with an
ambiguous return value, or do you throw exceptions?

I've made it habit to check all returns in my code, and usually, on
most projects, I'll have an error function that reports error messages
to some central location. I recently worked on a project where someone
suggested to me I was spending too much time writing error messages,
and that I was therefore missing the benefit of using a scripting...

I have a Access database that should have data for each weekday of the
year. There is a field called DateDownloaded, which should have at
least one record for each weekday of the current year.
Does anyone know of existing code that would check to make sure each
weekday has at least one record and if not, write that date to a temp
table or...

I was investigating a function to determine whether daylight saving
was being observed on a particular date (given the platform's regional
settings) and came across a suggestion at merlyn.com to test the time
zone offset on a variety of dates to see if it changes. Based on
that, I developed the following checkDST() function which, as far as I...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
