I would like you to help me out with the strings, which I find it difficulty to get from the html class. The first string I uses as pattern1 string, which it connected to the server to get the showtitle string from the html class, it is working fine. I couldn't be able to get the string on the second paragraph from the html class with pattern2 string, as the text goes on the blank. I need to get the string from the html class. The third pattern string, I am trying to get the string at the end of the html class so I got the blank text.

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,
Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs
So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I am using a database in Visual Basic 2010 displayed through a DataGridView. Through the DataGridView's "add query" option, I am writing these queries. My goal is to have partial search entries show up (ie if the entry is "Lewis" then it should be among the entries returned if "Le" is in the textbox.)
SELECT * FROM Table WHERE Surname LIKE '%' + @Surname + '%'
I am using the above query and it only returns exact matches despite the LIKE operator. Partial entries never show up despite the presence of the wildcard % symbol. It's as if the whole thing is being treated as an equal sign.What should I do? Is it a problem with the SQL itself or does VB's "add query" maker simply have such limited capabilities?

i have a bunch of radio buttons which can have different text displayed depending on whats retrieved from the database.however i want to add code that hides any radio button that would have a 'zero' retrieved from the database.so far this is the code i was coming up with, without getting into the nitty gritty of the actual database queries
If RadioButton1.Text = Me.HWExamsDataSet.DSExamTextA.Rows.Item.tostring = 0 Then
RadioButton1.Visible = False
End Ifabase entries or queries.
it looks like it may work...but is there a way to automate it so that i can put in a reference to ANY radiobutton like radiobutton(*).text? or a bunch of buttons if need be.i know theres a way to specify additional items to a given command...just can't remember if its curly brakets etc.

I'm using Visual Basic Professional 2010, I have two directories of XML files. The naming convention in directory one is a user's name, a six digit date and ending in ".xml_CREATE.xml". So, I perform some work on a file in directory two. During the course of that processing I discover that a file exists in directory one called "Mike" an unknown six digit date and ending with ".xml_CREATE.xml", so while I have no way to know the date, I know it exists and would look something like Mike030312.xml_CREATE.xml. So, now I want to load that file as an XElement that I will eventually incorporate into an XDocument, so I need to perform a Load similar to:
myXMLFile = XElement.Load(My.Settings.XMLDir & "" & Mike030312.xml_CREATE.xml),
However, since I don't know the date, I need to insert wildcards at that spot. How do I make that happen?

I have a large ASP.NET project where I want to do a mass search and replace (about 3500 instances)
I want to change
If strErrorMessage.Length > 0
If strSomeString.Length > 0
If strWhatever.Length > 0
and any other similar call to the Length method from a string to the following
If Len(strErrorMessage) > 0
If Len(strSomeString) > 0
If Len(strWhatever) > 0
Anyway to reliably do this in one shot?
I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0
This just won't work though as it won't understand how to rearrange it properly. Currently have VS2010 and N++ at my disposal.

I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?
