From: LondonLad on 5 May 2010 12:56 Hi xStr can contain a string which includes numbers or not contain numbers if it contains numbers I want to edit it. In my example which does not work xStr = "03 Best of Time" If IsNumeric(xStr) Then txtHold.Text = "Yes" Else txtHold.Text = "No" Can you help please Ron
From: Rick Rothstein on 5 May 2010 13:04 The Like operator can help out here... If xStr Like "*#*" Then ' xStr contains one or more digits Else ' All characters in xStr are non-digits End If -- Rick (MVP - Excel) "LondonLad" <LondonLad(a)discussions.microsoft.com> wrote in message news:B96BED25-0A88-4124-9E61-3B874330B57D(a)microsoft.com... > Hi > xStr can contain a string which includes numbers or not contain numbers > > if it contains numbers I want to edit it. > > In my example which does not work > xStr = "03 Best of Time" > > If IsNumeric(xStr) Then txtHold.Text = "Yes" Else txtHold.Text = "No" > > Can you help please > > Ron

The ancient Val function returns a Double if the string starts with a number. It stops conversion when it encounters a non-numerical character. If the string starts with a non-numerical character it will return 0. It's not localized, it recognizes only the dot as decimal sign. Spaces are totally ignored by Val. Here some examples: Val("123 that's for me") will return 123 but Val("1, 2, 3, that's for me") will return 1, because there is a comma after the 1. Val(".25 $") will return 0.25 Val("$ 125") will return 0, because the string starts with a non-numerical character Val("5 6 7 8") will return 5678 Val("- 12" will return -12 If you are certain about how your data looks like, and you want speed, Val may be your choice.

Before relying on it, try one like this: ? Val("123 E 45th Ave") -- Jim Mack Twisted tees at http://www.cafepress.com/2050inc "We sew confusion"

As I said, "if you are certain about the look of your data ..." I just forgot to add "and know about the quirks of Val". Helmut. |
