I have a list, and in my items are labeled like this:
"Work sound ex 0"
"Work sound ex 0"
"Home sound ex 14"
"Home sound ex 15"
"Home sound ex 16"
How can I just send the number in the selected list item to a variable so only "0", "14", "15", "16", etc. is sent and not the words like "home" or "sound"?

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

I'm trying to make a scheduling tool for my major at my school and I have a CourseEntryForm, RemainingCoursesForm and CoursesCompeltedForm.The CourseEntryForm has list boxes of courses that are required for graduation. I have been able to send the selected values of these list boxes to rich text boxes in the CoursesCompletedForm, however I need the courses that have not been selected in the list boxes to be sent to string that I can use in rich text boxes in the RemainingCoursesForm.I have tried using:ListBox.Items.ToString(RemainingCourses)when RemainingCourses is declared as string. I have also tried If statements to try to assign it, but I can never get it to work properly.

i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?

can't seem to find the answer to this anywhere.I need to know how to add an item in a list box above the currently selected item. I know there is a RemoveAt function which removes selected but is there any way to control where an item is added?

I'm having a problem with a program I am re-making. I used to be quite good at this stuff but I stopped and now I've pretty much forgotten everything. In hopes of gaining my knowledge back, I wanted to remake a program I made years ago but I'm having a problem.
I'm trying to split a selected item in a list box. This is what the item looks like:
|DATA|DATA|DATA|DATA/ELSE|
I can split it fine using this code:
Private Sub ListBox1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.Click
Dim LineofText As String

in VB10 Express is there a way to verify that something in a list box has been selected BEFORE an action can be taken? I was debugging and found an unhandled error when I accidentally told the program to do something, but there was nothing selected.

My listbox is bound to a datatable. The listbox is initially set to not show any data using selectedindex = -1.I have a second listbox that populates based upon the entry selected in listbox1. I use the Bindingsource PositionChanged event to populate the 2nd listbox.My problem is when the 1st entry in the listbox is selected the PositionChanged event does not fire, because the row selected is the default current position of the bindingsource. Can the Bindingsource be set to a "Null" position, I tried Position = -1 and that has no effect.

I've worked out how to create a DropDownList using the following code: <select id="salesPersonDropList" runat="server"></select> In my .aspx page, then my code behind loops through database output running:
Dim newListItem As ListItem
newListItem = New ListItem("Title", "Value")
salesPersonDropList.Items.Add(newListItem )
What I can't figure out is how to programatically set which of the List Items created is the one to be pre-selected in the rendered DropDownList, ie, how to create what I'd write in HTML as:

VB.NET Winforms Application... When a user starts typing in the search box of the application it automatically populates the name list dropdown box with the valid results and sets the droppeddown value to true... Everything is working fine except the fact that the user is forced to select a value from the name list or press the esc key because without doing so the mouse cursor just disappears and you have to move the mouse all the way outside the application for it to come back and it will only do so while outside the applicaiton.. Below is the code that I am using for this and it should be noted that I am using the droppeddown value else where in the application and none of those instances have an issue its only this one..
Private Sub u_lastName_Box_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles u_lastName_Box.TextChanged
u_nameLook_Box.Items.Clear()

I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.
