Change the Target .NET Framework Version of an Existing Project

This procedure describes how to change the .NET Framework version target of an existing project.

To change the .NET Framework version of a project

1. In Visual Studio 2008, open the project you want to change.

2. Right-click the project in Solution Explorer and then click Properties. Doing this displays the Project Designer.

3. Go to the Target Framework drop-down list. For Visual Basic projects, click the Compile tab and then click Advanced Compile Options. The Target Framework list is in the Advanced Compiler Settings Dialog Box (Visual Basic). For Visual C# projects, the Target Framework list is on the Application tab of the Project Designer. For more information, see Application Page, Project Designer (C#).

4. In the Target Framework list, click a .NET Framework version that is different than the current one for your project.

Your project now targets the new .NET Framework version. The project will unload and then reload in the integrated development environment (IDE).

Note:

If you change the .NET Framework target to an different version, you may receive error messages if your code contains references to earlier or later assembly versions. To resolve these errors, you must manually modify the references.

Extract Links From WebPage using VB.Net Regular Expressions

Sub Extract_Links_From_WebPage()

Dim oReg As Regex

Dim oMat As Match

Dim sInputString As String

Dim sLink As String

sInputString = "some have links that direct to some html files

"

oReg = New Regex("href\s*=\s*(?:""(?<>[^""]*)(?<>\S+))", RegexOptions.Compiled Or RegexOptions.IgnoreCase)

oMat = oReg.Match(sInputString)

While oMat.Success

sLink = oMat.Groups("link").ToString

End While

End Sub

The above code uses Group class, which represents the results from a single capturing group. Because Group can capture zero, one, or more strings in a single match (using quantifiers), it contains a collection of Capture objects. Because Group inherits from Capture, the last substring captured can be accessed directly (the Group instance itself is equivalent to the last item of the collection returned by the Captures property).

Instances of Group are returned by indexing the GroupCollection object returned by the Groups property. The indexer can be a group number or the name of a capture group if the "(?< groupname >)" grouping construct is used. For example, in C# code you can use Match.Groups[groupnum] or Match.Groups["groupname"], or in Visual Basiccode you can use Match.Groups(groupnum) or Match.Groups("groupname").

In the above example ?<>[^""]*stores the match found by [^""]* pattern in the group ‘link’, Which can be accessed by Groups("link")
