I'm trying to verify input given via an input box:

Code
-------------------
Sub copyData()
Dim varNameInput As String
myNameInput = Application.InputBox(prompt:="Enter a sheet name", _
Title:="Sheet Name", Type:=2)
Do While myNameInput = ""
MsgBox "You didn't enter a sheet name!", 16
myNameInput = Application.InputBox(prompt:="Enter a sheet name", _
Title:="Sheet Name", Type:=2)
Loop
If Not myNameInput = False Then
MsgBox myNameInput
End If
Exit Sub
End Su
-------------------


This works, however... Because I can't quite translate what's in m
mind into VBA, I'm stuck with the following cases which should al
trigger a failure MsgBox and repeat the loop:

- If the user enters a white space
- If the user enters a name with a white space
- If the user enters a name that doesn't match any of the sheets i
the workbook.

The latter, if I'm not mistaken, I need to do with Intersect, somethin
like (and please correct me if I'm wrong here):

Code
-------------------
If Not Intersect(myNameInput, Range("A1:A10")) is Nothing Then
... successful match, run necessary code ...
Else
... trigger failure again and go back to loop ...
End I
-------------------


I just don't know how to translate that into VBA.


And on a slightly different note, can an evaluation contain ORs? Fo
example, *If (myNameInput = "" || myNameInput = False || ...etc.) Then

Hi AMK4,
Bob's solution to your problem would be the way to go, I'm sure his
code is bullet-proof, but if you're interested in a solution that keeps
most of your original code see below (just for fun!)
All I did was throw in a for each/next loop to check the input against
the workbook's sheet names. I've included the Lcase bit so that the
user can get away with being lazy and not bother with capitals and
lower case in the input of the sheet name.

Sub copyData()
Dim Sht As Worksheet
Dim varNameInput As String
Dim booGoodInput As Boolean
mynameinput = Application.InputBox(prompt:="Enter a sheet name", _
Title:="Sheet Name", Type:=2)
Do While Not booGoodInput
For Each Sht In ActiveWorkbook.Worksheets
If LCase(Sht.Name) = LCase(mynameinput) Then
booGoodInput = True
Exit For
End If
Next Sht
If Not booGoodInput Then
MsgBox "You didn't enter a sheet name!", 16
mynameinput = Application.InputBox(prompt:="Enter a sheet name", _
Title:="Sheet Name", Type:=2)
End If
Loop
If Not mynameinput = False Then
MsgBox mynameinput
End If
Exit Sub
End Sub

I forgot, yes OR's can be used in comparisons...
If myNameInput = "" OR myNameInput = False Then

(What does || mean? I've not seen it before.)

I kept the Application.Inputbox <G

Very funny Bob!

Now see, this brings me to my next question: is there any advantage
between using Application.InputBox, or just InputBox?

I guess there are others as well where one can use one syntax versus
another, I just don't know if there's any real advantage. Someone
enlighten me please?


And while we're on the subject of my original question, I took Bob's
code (sorry Ken, his came in first) and added another piece to it:

Code:
--------------------
Do While Not ValidPage
myPageInput = Application.InputBox(prompt:="Which form should this go on? (1 through 4)", _
Title:="Form number", Type:=1)
If myPageInput = 0 Then Exit Sub
ValidPage = True
If myPageInput <1 OR myPageInput 4 Then
ValidPage = False
End If
If Not ValidPage Then MsgBox "Only values beteen 1 and 4 are allowed.", 16
Loop
--------------------


Two things:
a) if one just hits the return key, Excel pops up it's standard
'formula error' message. Like when you enter a bad formula in a cell.
Um, why?

And b) I need to make it so one can not enter '0' either, which at the
moment will act as if you hit Cancel.

The primary difference is that Application.Inputbox allows limited in-flight
validation of the data, give a type of 1 and you cannot input text. Best of
all is type 8, as this allows you to drop into a worksheet and specify a
range.

Am I correct in assuming that either would work at any time then, or
are there cases where one would fail while the other won't? I'm trying
to learn all these little quirks and improve on my own coding.

Anyone want to try and explain/tackle the second part of my question
(in my last message)?

Actually, with Bob's code, whether I type in 'CheckThisOut' or
'checkthisout', it always matches the sheet (providing it actually
exists.) I'm not concerned with UpPErlOwERcaSe matching to be honest.

But I like the fact that there are different approaches to the same
solution (essentially). Makes me take a look at both of them and
maybe, just maybe, have some of it seep through into my brain...

And the || comes from another C-like language (rather distant now) I
used to code in:
Code:
--------------------
|| - OR
&& - AND
--------------------

And the usual (to me):
Code:
--------------------
<eval ? return_1 | return_2
Which is the same as:
If <eval Then return_1 Else return_2
...but without the closing End If
--------------------

Hi AMK4,
I usually go for Application.InputBox for the same reasons as Bob. The
first thing I tried with your problem was to use Type:= 8 then click a
worksheet tab, I know it's not a range, but it was worth a try. I got
my hopes up when Sheet3! appeared in the text box. My hopes were
quickly dashed when the error message popped up.
It's interesting that Bob's code, without the use of LCase or Ucase,
leads to the input not being case sensitive. I can't see how he's
managed that (damned clever).
Thanks for clearing up the ||'s for me.
