VS 2010: String Manipulation - Cycle Through Every Item In The Listbox And Find The Ones That Have Been Checked
May 31, 2012
[Code]...
Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.

The Code below is a sample of what I am using.

I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.

I have a list box with groups of people and is displayed as such:
Paul Mary John
Frank Steve Bill
Jacob Dan Spongebob
and so on...
If i use the code below i can find and auto highlight Paul, Frank, Jacob but never finds anyone after the first like Mary, or Bill.
Dim findperson As String
findperson = CStr(TextBox1.Text)
ListBox1.SelectedIndex = ListBox1.FindString(findperson)
Essentially it is for quick reference for people to find who will be in their groups.

I'm trying to write a small app which can be used in order to log off Citrix Sessions. Citrix Sessions can be logged off via cmd or a batch file using this method:
[Code]...
So basically what I want to do is to select each listbox item that matches one of the hits from the cmd command. Probably the servername that gives a different result than "No User exists for" How can something like this be achieved?

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?

i have a listbox that contains the words "week1", "week2",all the way up to "week52" and when i select a week from the listbox it will retrieve a value from a mysql database that will represent a progress bar value. my progress bar has a range of 0-120 and i would like to have all the weeks that have values higher than 100 to be highlighted or marked somehow, in the listbox. so my question is, "is there a way to set the background color of certain weeks in the listbox to orange based on the value that they represent on the database?
for example for "week1", the value is 114, so when the listbox loads, i want the background color of the item "week1" in the list to be orange (indicating that it's current value is higher than 100)? i know that this requires me to implement a user defined drawing function for the listbox items but i dont know where i would even start. i would like this to be somewhat automatic so that it checks the values and changes the background colors of any value higher than 100, instead of me specifying a name of the item.

The homework assignment goes like this: write a menu-driven program to manage an employee list. the names should appear in the listBox when the form is loaded. When a name in the listBox is highlighted the name and number txtBoxes are loaded with the correct name and employee number. Use the Update menu items--modify,add,delete to edit the listBox items.When the Exit menu item is clicked the new employee list should be written to the text file and the program should terminate.
Well, the first part was completed successfully, but when I tried to delete a name and number I recieved an error box that said "InvalidOperationException was unhandled", "sequence contains no elements" that pointed to line 35. msdn and help were no help, talked about dataset tables? Did I use the incorrect syntax? Once I resolve this issue, the other two--modify,add should be similar, but then how do I reconstruct the text file so that it will properly load the next time the form is loaded?
