Say I have a listbox, and the items in the listbox look like this:
#COLORS#
GREEN
BLUE
BLACK
#NAMES#
BOB
JIM
BILL
#ETC#
How would I make it to where when a user clicks a button, all the text between #COLORS# and #NAMES# is removed? Let me know if you need more detail

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 have many strings in a two column text file. The first column is the start position, the second one is the string.

The second column contains 100 chars.Obviously these strings have overlapped, if a start position is given and the string length is given. How to merge them together? Ex, I want start point is 38781735, end point is 38781900. The string length is 38781900-38781735+1

I'm writing a small 2D engine that uses Lua to control it. I've been setting events up in between the Lua and the VB.net for the past little while here. The problem, I've realized, is that is that I can't seem to remove the events which is screwing up quite a few things (because they are being called when they should be done with). To fix this, I wanted to add some kind of way to remove the specific event handler.
I know how to add an event handler:AddHandler Button1.Click, AddressOf Button1Clicked
But with this in mind, is their a way to remove a specific event handler in the VB.net? I didn't explain this very well: If I have this:
[Code]...
Private Sub paint_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
and uses the E.graphic.Drawimage function

I tried this code to remove specific Rows that the column(0) cells equal= 0
For i As Integer = 0 To Form1.DataGridView1.Rows.Count - 1
Form1.DataGridView1.Rows.Remove(Form1.DataGridView1.Rows(i).Cells(0).Value = 0)
I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
im trying to find a specific text in a textbox and remove it . i don't figure a way to do it .
If richtextbox1.text.contains(listbox1.selecteditem) then
' there i dont know how delete the text !!
end if
I'm making a button to delete lines not containing specific text.
For example, if the text is "test". I want to remove all lines not containing "test" in it.
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?
View 2 RepliesI do have a customized treeview which inherits from treeview. The customized treeview offers - amongst other - the functionality to automatically check/uncheck the child and parent nodes according to the selected node.To do so, I use (or mabye abuse?) the AfterCheck-event of the treeview in the class where the inherited treeview is customized. Code looks like that (Submethods not included):
[code]...
I temporarily remove the AfterCheck-Event in the event-procedure to avoid it getting fired when I programmatically check/uncheck the checkboxes of the treeview. Works fine so far, only problem I see: if another programmer wants to use the customized tree view and tries to make use of the After-Check-Event, he'll get caught in an infinit loop, because his own After-Check-Event (he added himself to the treeview) was not removed and keeps on firing every time a checkbox is automatically checked/unchecked.
How can I remove ALL methods linked to AfterCheck-Event without knowing which method someone added to the treeview-control? My guess is to use reflection and to get the underlying delegate of the AfterCheck-Event by using the .GetInvocationList somehow - but I was not able to make it work.

I have a form with four checkboxs and a textbox for an id number.I also have two tables in a database. The first has a column for the users Id, Name, and a column called Points.The second has a column for Id and one called Letters.What i want to do is, after the user enters the id number, and the user clicks checkboxA it should add a certain number, lets say 5, to the "points" cell for that id#(in the first database), and it should put the letter "a" in the "letters" column (of the second database) for that id number. Also, if a user deselects a checkbox it should remove the "a" from letters and subtract 5 from points.Also there will be different letters in the "letters" cell, so i cant just clear it, but i have to remove the specific letter.

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"
