Regex :: How To Write Regular Expression
Sep 14, 2010My coworker needs me to write him a regular expression for his vb.net app.I do not know vb and he does not know regex.The regex he needs is:/.*web id: ?(d+).*/iBasically he needs to search a string for something like "web id: 345" or "web id:2534" and retrieve the ID.He took what I gave him above and was able to put this together:
Dim strPattern As String = ".*web id: ?(d+).*"
Dim strReplacement$ = "$1"
GetWebId$ = Regex.Replace(LCase$(strNote$), strPattern$, strReplacement$)

Write A Simple Expression-like Class In .NET 2.0?
Jul 7, 2010I'm currently working in .NET 2.0 Visual Basic. The current project is an Active Directory Wrapper class library within which I have a Searcher(Of T) generic class that I wish to use to search the underlying directory for objects.
[Code]...
In short, I want to offer some kind of Expression feature to my users, unless it is too much work, as this project is not the most important one and I don't have like 2 years to develop it. I think that the better thing I should do is to write something like CustomExpression that could be passed in parameters to some functions or subs.
C# - How To Write A Multi-line RegEx Expression
Jan 12, 2010I have a vb.net class that cleans some html before emailing the results.
Here is a sample of some html I need to remove:
<div class="RemoveThis">
Blah blah blah<br />
Blah blah blah<br />
[Code]...
I am already using RegEx to do most of my work now. What would the RegEx expression look like to replace the block above with nothing?
I tried the following, but something is wrong:
'html has all of my text
html = Regex.Replace(html, "<div.*?class=""RemoveThis"">.*?</div>", "", RegexOptions.IgnoreCase)

C# - Lambda Expression: CS To .Net?
Aug 24, 2011I am dumb founded at this statement....maybe its just too many hours/days of doing C# to VB.Net conversion but i am drawing a blank on this conversion.
List<string> sColors = new List<string>(this.CustomPaletteValues.Split(','));
try {
List<Color> colors = sColors.ConvertAll<Color>(s => (Color)(new ColorConverter().ConvertFromString(s)));
What i have so far:
Dim colors As List(Of Color) = sColors.ConvertAll(Of Color)(....)
As you can see its the content of the lambda that i am hitting a brick wall with.
C# - When Are ASP Expression Builders Most Useful
Jun 16, 2009I saw an example of using Expression Builders, and creating your own Custom Expression Builder Classes here: [Url] However, I fail to see the value in using this approach. It doesn't seem much easier than programmatically setting values in your code behind. As far as I can tell, the only thing you can do with them is set properties. Maybe they would be useful for setting defaults on certain controls? Can anyone shed light on where this ASP.NET feature becomes powerful?
