Userform/Textbox Issues
I have a userform with a few textboxes, all of which run the same
code. I was wondering if there was a way to link them to the same section of code. The code each one runs is below: Private Sub TextBox1_Change() If IsNumeric(TextBox1.Text) Then If TextBox1.Value < 1 Or TextBox1.Value 12 Then TextBox1.Value = Month(Date) MsgBox "This box is intended to indicate the month and" & _ vbCrLf & "will only accept values between 1 and 12" End If Else TextBox1.Value = "" End If End Sub |

Userform/Textbox Issues
Hi Mastermind,
See John Walkenbach at: Handle Multiple UserForm Buttons With One Subroutine http://www.j-walk.com/ss/excel/tips/tip44.htm John's technique can readily be adapted to your TextBoxes. --- Regards, Norman "mastermind" wrote in message ps.com...

Userform/Textbox Issues
By way of introduction (to the regulars in this newsgroup), my area of
specialty is the compiled version of VB; so, while there are major differences between the platforms (compiled VB versus VBA), there is a lot of code similarities too. This will allow me to contribute (in a limited way) here. Below is an example of that. Oh... for the regulars here... obviously I will trip over built-in VBA functionalities that don't exist in the compiled versions of VB... please be kind when pointing out these mistakes when I make them.<g If IsNumeric(TextBox1.Text) Then The above test is not as fool-proof as I think you think it is. Here is the response I post over in the compiled VB newsgroups whenever some uses IsNumeric to test more than a single character entry for its being a number... I usually try and steer people away from using IsNumeric to "proof" supposedly numeric text. Consider this (also see note below): ReturnValue = IsNumeric("($1,23,,3.4,,,5,,E67$)") Most people would not expect THAT to return True. IsNumeric has some "flaws" in what it considers a proper number and what most programmers are looking for. I had a short tip published by Pinnacle Publishing in their Visual Basic Developer magazine that covered some of these flaws. Originally, the tip was free to view but is now viewable only by subscribers.. Basically, it said that IsNumeric returned True for things like -- currency symbols being located in front or in back of the number as shown in my example (also applies to plus, minus and blanks too); numbers surrounded by parentheses as shown in my example (some people use these to mark negative numbers); numbers containing any number of commas before a decimal point as shown in my example; numbers in scientific notation (a number followed by an upper or lower case "D" or "E", followed by a number equal to or less than 305 -- the maximum power of 10 in VB); and Octal/Hexadecimal numbers (&H for Hexadecimal, &O or just & in front of the number for Octal). NOTE: ====== In the above example and in the referenced tip, I refer to $ signs and commas and dots -- these were meant to refer to your currency, thousands separator and decimal point symbols as defined in your local settings -- substitute your local regional symbols for these if appropriate. As for your question about checking numbers, here are two functions that I have posted in the past for similar questions..... one is for digits only and the other is for "regular" numbers: Function IsDigitsOnly(Value As String) As Boolean IsDigitsOnly = Len(Value) 0 And _ Not Value Like "*[!0-9]*" End Function Function IsNumber(ByVal Value As String) As Boolean ' Leave the next statement out if you don't ' want to provide for plus/minus signs If Value Like "[+-]*" Then Value = Mid$(Value, 2) IsNumber = Not Value Like "*[!0-9.]*" And _ Not Value Like "*.*.*" And _ Len(Value) 0 And Value < "." And _ Value < vbNullString End Function Here are revisions to the above functions that deal with the local settings for decimal points (and thousand's separators) that are different than used in the US (this code works in the US too, of course). Function IsNumber(ByVal Value As String) As Boolean Dim DP As String ' Get local setting for decimal point DP = Format$(0, ".") ' Leave the next statement out if you don't ' want to provide for plus/minus signs If Value Like "[+-]*" Then Value = Mid$(Value, 2) IsNumber = Not Value Like "*[!0-9" & DP & "]*" And _ Not Value Like "*" & DP & "*" & DP & "*" And _ Len(Value) 0 And Value < DP And _ Value < vbNullString End Function I'm not as concerned by the rejection of entries that include one or more thousand's separators, but we can handle this if we don't insist on the thousand's separator being located in the correct positions (in other words, we'll allow the user to include them for their own purposes... we'll just tolerate their presence). Function IsNumber(ByVal Value As String) As Boolean Dim DP As String Dim TS As String ' Get local setting for decimal point DP = Format$(0, ".") ' Get local setting for thousand's separator ' and eliminate them. Remove the next two lines ' if you don't want your users being able to ' type in the thousands separator at all. TS = Mid$(Format$(1000, "#,###"), 2, 1) Value = Replace$(Value, TS, "") ' Leave the next statement out if you don't ' want to provide for plus/minus signs If Value Like "[+-]*" Then Value = Mid$(Value, 2) IsNumber = Not Value Like "*[!0-9" & DP & "]*" And _ Not Value Like "*" & DP & "*" & DP & "*" And _ Len(Value) 0 And Value < DP And _ Value < vbNullString End Function Rick |
