[AccessD] Bang and Dot operator in Runtimes.

One place where it makes a difference is if you don't have Option
Explicit turned on.  In that case, not using the Me in referring to an
object and misspelling the name of the object will result in the
compiler interpreting the item as a variable.  If you do have Option
Explicit turned on (and we all do, right?), misspelling the name of an
object will cause a runtime error telling you the variable wasn't
declared.  Using the Me gives you a more useful message that it can't
find the object.

Boy, I kind of feel it's dangerous not to be more explicit when
identifying a particular control.

I've been using access since it's birth and hardly see any code examples
that don't include some type of identifier. Am I losing it or something.

Anyone else have any input?

It's just:

txtDate = #1/1/2001#

or 

cboPerson = "Dan Waters"

or 

lblName.Caption = "Full Name"

or 

chkPerson = True


Yes - when I use a Wizard to create Report, the controls do get the same
names as the fields.  So, to make sure I (and Access) know what I'm
referring to, I always change the control names so they use a naming
convention.

I've never come across the need to used .Value - so far anyway!

Gee, I've been doing that since version 1.0.
How else do you refer to a control on the form besides using Full
syntax?

Froms!frmMainForm!txtDate = #1/1/2001#  ?

Or using a With (which uses the "." operator)

With txtDate
    .Height = 2000
    .Width = 2000
    .Caption = "This is MyLabel"
End With

Maybe I should use me.txtDate.Value?  

But, I've had issues with ".value"  in the past. Don't remember what the
Issues were but from past experiences I've avoid using .value if I can.

As you suggested, you could drop it all together and sometimes it works,
but if you have a field name behind the form and a text box name with
the same name, it will get confused.

John,

I never use the me. or me! syntax on any forms or reports to simply
refer to a textbox, combobox, checkbox, label, etc.

Could you just remove it altogether?

I've been able to fix this by making some changes in code but want to
know if anyone has additional info on why this occurs.

Sometimes, referring to a text box with the "." operator sometimes fails
in runtime apps.

me.txtDate = #1/1/2001#  'Causes an error Vs.
Me!txtDate = #1/1/2001#

The error message I get is that the dot operator is invalid.

I simply change it and it's fine. Yet, on other forms, it's working.

I re-import and uncompile/compile many times on these apps and it still
doesn't seem to always catch the potential problem.

Any thoughts?

John
