Re: [MS_AccessPros] Re: What does the colon do in the ELSE: statement?

Setting Dirty to False raises an error if it is already False.

I can't see Microsoft investing anything in making VBA more mainstream, they would rather it just goes away.

But in your example, if you want Me.Dirty to be False regardless, why not just use

Me.Dirty = False

If you want to toggle it, I use

Me.Dirty = Not Me.Dirty

I like that the editor has lots of "AutoCorrect" features. I do that lower case variable thing, too. It makes it so easy to catch typos.

Another thing that might eventually go away if VBA gets to be more like more mainstream syntax is the assumption of "True" as in:

If Me.Dirty Then Me.Dirty = False

Not only is that a single line code but the use of "Me.Dirty = True" can be written as I did above. The compiler gets that I mean True without typing it.

Bill

It will compile Bill, but I don't like it :)

I never use multiple statements with an Else. I used to be very 'correct' with no else and code it like

If suit = spades Then

MsgBox "I win!"

End If

But I admit I prefer single lines and that is what I use now (does cause some small problems when trying to check back on multiple nested Ifs when there is one without an End If, but nesting usually helps here).

BTW, typing endif and getting End If is great in my view, I always do it and love that VBA corrects it (in the same way that I never type my variables in the define came-case, I type them lower-case and if they don't get corrected I know I have typed it incorrectly – we need all the help we can get), but I just wish it would work with endwith as well!

Bob - It's a non-nonsensical example made worse by being syntactically incorrect to start with.But my example is correct and will compile as it should.

While multiple statement lines are out of the ordinary, they are used from time to time. It's a matter of style. I tend to use them in If blocks if the Else line is short. Offhand, I can't think of any other place I'd use them.

Then there is the one-line If statement:

If suit = spades Then MsgBox "I win!"

No End If needed.

Another funny thing about VBA, you can type endif and the editor will fix it for you.

Surely, it should be

If 1 > 4 Then

MsgBox "1 is greater than 4"

Else

MsgBox "1 is less than 4"

End If

Or even

MsgBox "1 is " & IIf(1 > 4, "greater", "less") & " than 4"

Multiple statement lines just don't feel right to me.

As per Duane's explanation, the code should have been written:

If 1 > 4 Then

MsgBox "1 is greater than 4"

Else: MsgBox "1 is less than 4"

End If

I found this while searching the web http://stackoverflow.com/questions/7649101/excel-vba-pound-and-colon-signs-meaning

"The colon (:) is a statement delimiter. It would be equivalent to a new line in VBA, or a semicolon in C (just to quote a random example). It allows you to write several instructions on a single line rather than going to a new line each time."

Since your example code has not instruction on the same line after the ":" it serves no purpose.

Hello

I am trying to understand the "ELSE:". Why is the colon necessary? What does it do there?

Thank you

Phucon

Sub IF_ELSEIF_FUNCTION()
If 1 > 4 Then
MsgBox "1 is greater than 4"
Else:
MsgBox "1 is less than 4"
End If
End Sub
