Hi,

I feel fooled.. In the immediate window, if I enter

? DateTime.Now.Kind

I get "Unspecified {0}". The result - I expected "local" - lead to some time
consuming deliberations. Today, I execute

MsgBox(DateTime.Now.Kind)
MsgBox(DateTime.Now.Kind.ToString)

as part of the source code, and I get "2" and "local" (where 2 = local, so
this is consistent).

Why does the immediate window lie? There, If I execute

?DateTime.Now.Kind.ToString

I even get the message "Run-time exception thrown :
System.ArgumentException - Cannot find the method on the object instance."

What? Did I overlook anything?

The fact that you cannot issue that statement like that, because it needs an
object to work with to complete the statement.

dim strhldkind as string

strhldkind = datetime.now.kind.tostring

Now, after executing that statement in code, the *strhldkind* is now an
*object* and in the immediate window you can enter this.

?strhldkind

It will show *local*

or you could have done this in code

dim strhldkind as string = datetime.now.kind.tostring

It is a complete statement. The result of the ToString method *is* an
object, it's a String. The "?" (aka print) command prints strings like they
are. It can take any expression as an argument, be it one simple variable
like strhldkind or be it a more complex expression. It does work with
"?datetime.now.kind", so why shouldn't it work with one more ".tostring"?
Just because it's one more dot? This doesn't make sense.

Or, why does, for example,
"?System.Windows.Forms.Screen.PrimaryScreen.BitsPerPixel" work as well as
"?System.Windows.Forms.Screen.PrimaryScreen.BitsPerPixel.ToString"?
without an exception?

strhldkind = datetime.now.kind.tostring

Well, the problem is that it should also work like I explained before.

In addition, it is still wrong that it outputs "unspecified" in the
immediate window whereas I get "local" in the code.

I'm inclined to believe it is a bug. Because it displays properly in
the Immediate window when using C#, but I get the same results you do
when using VB.
