[code]Now how can I check if a certain employee is in the list? ie. I want to know if "John Smith" is in Employees. I see there is a .Contains method but I can't figure out how to use it on a ListIf Employees.Contains(???) Then (need to check for "John Smith" here)

I have a checkedlistbox with numbers in it and I'm trying to load a list of numbers from a database and check all of them (they should all be in the checkedlistbox).
I was trying to do this by loading all the values into a separate listbox using my own subroutine (I know that part works) and then finding the corresponding item on the checkedlistbox, like this:
Dim ItemName As String
For Each item In ListBox1.Items
ItemName = ListBox1.GetItemText(item)
If CheckedListBox1.Items.Contains(ItemName) = true Then
CheckedListBox1.SetItemChecked(CheckedListBox1.Items.IndexOf(ItemName), True)
End If
Next
End If
But this doesn't work: It never returns a match, even when the item is definitely on the list. How do I make this work?
I am working on a program that gathers test scores from the user in the form of a list box (array preferably). I need to be able to check the user's entries to validate they are between 0-100. I have tried using If statements with a messagebox.show() error message.When the user enters an invalid entry the error messagebox pops up but after selecting ok the program moves on to the next test score.
The GetTestScores procedure gathers the students test scores from the user
Sub GetTestScores(ByRef intTestScores() As Integer)
Dim intCounter As Integer = 0

I wanted to make a collection of definitions public, for which the Enum class was a perfect candidate, but I also had the need to check variables against all the possibile enum members to see which one they were.
In this scenario my solution was to write a public enum class in which all the members were made available, and replicate the same listing in an array in order to iterate through.
In fact the only way I know to iterate through all memebers is a cycle (either "for each" or "while somecondition" and a moving index). But I guess there must be a simpler way to make use of an enum class.
I want to read a number of items from a file and then associate each of those items with a new button at run-time, so that when the user clicks one of the buttons I can display some information about that item.Can I use a LIST to manage these buttons and items? Can I create a new class and have each list item of that class, such as 'btnID', 'btnText', etc... ?

So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is

I don't want to have to declare & initialize two lists if I can avoid it. Edit: I should have mentioned that this is a simplified example - there are actually a dozen or so CASE statements, and Foo() and Bar() are actually placeholders for quite a bit more code - it's seeing the same block of code repeated over and over that got me thinking about a better way to do it.

I am new to Vb.net so I will need some handholding. I have been searching everywhere but can't find what I need.I'm creating an app that has two forms.Each form has two comboboxes.The comboboxes are populated via a list and the list is populated by reading a text file for each combobox.The second form is called from the main form to modify the entries in the comboboxes. When I select the displaymember in the combobox a value corresponding to that entry is displayed in the text box.Now here is what I need.
I need to be able to append new values to the list so when focus is returned to the main form the new value is present. I'm using a combobox and a textbox on the second form as the import.The combobox is used to either select a present value to be able to modify the value in the textbox, or is used to add a new list element.

I work in MS Visual Studio 2008, I have a VB.NET Solution which has three Projects, BusinessObjectLibrary (object properties), DataAccessLibrary (object functions such as selectAll, exportToExcel) and WindowUserInterface (UserForms c/w Controls)In my WindowUserInterface (project) I have a form called "rolFormGrid.vb", on this form, I have a DataGrid that gets filled with a function called "selectAll" when the form is loaded, I also have a button that calls the function "exportToExcel" and I have a Progress Bar called "rolProgressBar" ***.
In my DataAccessLibray (project) I have a class called "ROL_Adapter.vb", and in this class resides the function called "exportToExcel" which has all the code to create an Excel Workbook. When this function is being called, it can takes close to a minute to export to excel. We all know how users can be impatient if they do not see anything happening in the foreground when an application is working, that is the reason I want the progress bar.

I am working with LINQ to XML in VB (although answers in C# are great, too). First off- my code works, so this is not critical. However, I can't help but think that what I'm doing with conditional logic should already be doable using the LINQ query itself. Here's what I've got:
'Get the Description elements in the ResultData section where the value is "Op Code"
Dim opCodes As List(Of XElement) = (From c In xdoc.Descendants("ResultData").Descendants("Description")
Where c.Value = "Op Code"[code].....
Please don't be too critical of my method of locating the sibling nodes- the XML files are produced by a third-party testing device and this is the only generic way to get the values I need. What I'm really looking for here is a better way to handle the If block.

Using 'TypeOf', I correctly see that pn is a properNoun, a noun and a word. The problem is, using 'GetType' to check pn against a string value, I can only see that pn is a properNoun, not that its parent classes are noun and word.
