Don't really know what kind of regular expression you wish to build but you can get the position by something like this otherwise:<br />
<br />
&nbsp; &nbsp;Private Function CheckPosition(ByVal Mystring As String) As Short<br />
&nbsp; &nbsp; &nbsp; &nbsp; Dim z, y, x As Integer<br />
&nbsp; &nbsp; &nbsp; &nbsp; y = TextBox1.Text.Length<br />
&nbsp; &nbsp; &nbsp; &nbsp; For x = 0 To y - 1<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; If IsNumeric(TextBox1.Text.Su<wbr />bstring(x,<wbr /> 1)) Then<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; y = x + 1<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Exit For<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; End If<br />
&nbsp; &nbsp; &nbsp; &nbsp; Next<br />
&nbsp; &nbsp; &nbsp; &nbsp; Return y<br />
&nbsp; &nbsp; End Function

Hi,<br />
<br />
I hope that someone is able to help. I am looking at writing a reg expression to try and find the first numeric value in a string (values from 0-9).<br />
<br />
This string is going to be a postcode field so i need to find the first numeric value for the trim. This will either be a one or two value string field.<br />
<br />
Regards,<br />

Regular expression in vb.net

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Visual Basic.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
