why the two number after the decimal point are always converted to two zeros

[piscis]

Gentlemen:

 

 

Does anyone knows why the two number after the decimal point are always converted to two zeros with the code below?

 

Example:

 

If the real value was 175.53

 

I only get 175.00

 

Why is this?

 

Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click

       Dim MyRegEx As New Regex("=\s+(?<MyPat>\d+)")
       Dim s As String = txtDataView.Text
       Dim Mc As MatchCollection = MyRegEx.Matches(s)
       Dim M As Match
       Dim i As Integer
       If Mc.Count > 0 Then
           i = 0
           For Each M In Mc
               i += 1
               PutInTextBox(Me, "TextBox" & CStr(i), M.Groups("MyPat").Value)
           Next
       End If

   End Sub



   Private Sub PutInTextBox(ByVal ContainerCtrl As Control, ByVal TBName As String, ByVal msg As String)
       Dim ctl As Control
       For Each ctl In ContainerCtrl.Controls
           If TypeOf ctl Is TextBox And ctl.Name = TBName Then
               ctl.Text = msg
               Exit For
           Else
               PutInTextBox(ctl, TBName, msg)
           End If
       Next

       TextBox75.Text = Sd
       TextBox76.Text = St

   End Sub

I am just starting to work with regular expressions so excuse me if I'm off base, but doesn't \d+ match one or more instances of a digit? So wouldn;t that stop at the decimal point?

Thanks, What would be your suggestion?

I am not sure. Since a dot signifies any character except newline, you need a way to override that an just look for a character dot. I'm not sure of the answer.

This is untested, but try this. It adds one optional decimal point followed by 0 or more digits:

 

"=\s+(?<MyPat>\d+[.{0,1}][\d]*)"

 

You might need a backslash in front of the "." but I don't think so.

 

The {0,1} says 0 or 1 occurrences of the ".". The final \d with a * says 0 or more digits. If you really want 0, 1, or 2 digits you can change it.
