What did you mean when you said...

I am having trouble getting this to work in Excel 2007;
Vista whereas works Excel 2003 XP.

....that code works the same in XL2007 as it does in XL2003 (both running on
Vista) for me. A numerical value entered into a TextBox is not a number, it
is text. The only reason entries like 1, 2.3, etc. end up as numbers when
used in calculations is because VBA has native data types that hold such
values (Long, Double, etc.) and, when used in calculations, numbers that can
be converted to an appropriate native data type are done so, in the
background, automatically, in order to perform the required calculation. VBA
has no native data type for fractions, so no conversion takes place. You can
parse the fraction and convert it to a floating point value in code though.
Here is a function that I have posted in the past (in the compiled VB
newsgroups) which will convert fractions, as well as mixed numbers (whole
numbers followed by a space followed by a fraction), into a floating point
values...

Function FracToDec(ByVal Fraction As String) As Double
Dim Blank As Integer
Dim Slash As Integer
Dim CharPosition As Integer
Dim WholeNumber As Integer
Dim Numerator As Integer
Dim Denominator As Integer
'Remove leading and trailing blanks
Fraction = Trim$(Fraction)
'Collapse all multiple blanks to a single blank
CharPosition = InStr(Fraction, " ")
Do While CharPosition
Fraction = Left$(Fraction, CharPosition) & _
Mid$(Fraction, CharPosition + 2)
CharPosition = InStr(Fraction, " ")
Loop
'Remove any space character after the slash
CharPosition = InStr(Fraction, "/ ")
If CharPosition Then
Fraction = Left$(Fraction, CharPosition) & _
Mid$(Fraction, CharPosition + 2)
End If
'Remove any space character in front of the slash
CharPosition = InStr(Fraction, " /")
If CharPosition Then
Fraction = Left$(Fraction, CharPosition - 1) & _
Mid$(Fraction, CharPosition + 1)
End If
'Locate the blank and/or slash
Blank = InStr(Fraction, " ")
Slash = InStr(Fraction, "/")
'The Fraction argument can't have characters other than
'blanks, slashes, digits and it can only have one blank
'and/or one slash.
If Fraction Like "*[! /0-9]*" Or _
InStr(Blank + 1, Fraction, " ") Or _
InStr(Slash + 1, Fraction, "/") Or _
(Blank 0 And Slash = 0) Then
MsgBox "Error -- Improperly formed expression"
'The Fraction argument is now in one of these formats
'where # stands for one or more digits: #, # #/# or #/#
Else
'There is no slash (Format: #)
If Slash = 0 Then
FracToDec = Val(Fraction)
'There is a slash, but no blank (Format: #/#)
ElseIf Blank = 0 Then
FracToDec = Val(Left$(Fraction, Slash - 1)) / _
Val(Mid$(Fraction, Slash + 1))
'There are both a slash and a blank (Format: # #/#)
Else
FracToDec = Val(Left$(Fraction, Blank - 1)) + _
Val(Mid$(Fraction, Blank + 1, _
Slash - Blank - 1)) / _
Val(Mid$(Fraction, Slash + 1))
End If
End If
End Function

Hi,

Textboxes (unsurprisingly) return text so you need val

mynumber = Val(UserForm1.TextBox2.Value)

The Val function will not convert fractions to floating point values; it
will print the numerator only.

Make a Textbox (I used the Drawing Toolbar). Enter 3/4

Run the following:

Sub Macro1()
Dim s As String
ActiveSheet.Shapes("Text Box 1").Select
s = Selection.Characters.Text
MsgBox (Evaluate(s))
End Sub

Outputs .75

Rick,

VBA doesn't have native fraction value use, but Excel does, and you can
leverage that ability.

The cell that you use could be anywhere, including a hidden sheet in an
add-in.

And you can do this
'Remove leading and trailing blanks
Fraction = Trim$(Fraction)
'Collapse all multiple blanks to a single blank

by using Appliction.Trim, which removes leading, trailing, and multiple
internal spaces.

And note the use of a Sub rather than a Function definition.

Clearly, my code isn't as robust (not looking for extra /'s, non-numeric
characters, for example),
but, hey, it's just an example. ;-)

Bernie

Option Explicit

Sub TestIt()
Dim myValue As Double
FracToDec " 1,230 5 \ 6", myValue
MsgBox myValue
End Sub

Sub FracToDec(ByVal Fraction As String, ByRef myDV As Double)
Dim myC As Range
Fraction = Application.Trim(Fraction)
Fraction = Replace(Fraction, "\", "/")
Fraction = Replace(Fraction, " /", "/")
Fraction = Replace(Fraction, "/ ", "/")
Set myC = Cells(Rows.Count, 1).End(xlUp)(2)
myC.NumberFormat = "G"
myC.Value = Fraction
myDV = myC.Value
myC.Clear
End Sub

Gary''s Student,

Evaluate is an excellent idea - much better than my using a range object -
but with a little extra code to clean things up, since evaluate doesn't like
commas...

Bernie

Dim myValue As Double
myValue = FracToDec(" 1,230 5 \ 6")

Fraction = Replace(Fraction, " /", "/")
Fraction = Replace(Fraction, "/ ", "/")
Fraction = Replace(Fraction, ",", "")
FracToDec = Evaluate(Fraction)
End Function

Hi,

Thanks for the correction, I'm aware of that but misread to post I thought
the problem was simply getting numbers from a textbox.
