Selected Listbox Item To Trackbar Values?
Mar 9, 2010
I have a little problem. Basicly, I have a ListBox, TrackBar, TextBox and 2 Buttons. What I want now is that:
1. If user clicks on Button1, the program will add text from TextBox to ListBox (I know code for that one).
2. When user clicks on ListBox item, ListBox item selected, and then clicks on Button2, program will set the value of SelectedItem to TrackBar. Here's an example:
User writes "Value is 50." in TextBox, clicks on Button1 and program adds "Value is 50." to ListBox. Now user selects ListBoxItem and clicks on Button2. Program sets TrackBar value to 50.

In my application I have a listbox and SelectionMode should be MultiSimple because users need to see which items they selected. In another tab we have another listbox this one should show all the selection users had done in first tab. Private Sub

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
[Code]....

I have a form with a list box and a button. The list box is filled with text files from a folder. When you click the button whatever file is selected in the list box is then opened and each line of that file is added as an item in a list box on another form.I'm not sure what to code for if something in the first list box is not selected.

My code follows. I have six items (indices 0-6) and I'm trying to check if one has been selected or not. If not, then messagebox yells at you to select one. If it does, it tells you what you have selected. I'm having a horrible brain fart and contemplated coming here for about 45 minutes as I couldn't get it.
If ListBox1.SelectedItem.ToString <> "" Then
MessageBox.Show("You selected " + ListBox1.SelectedItem.ToString)
Else
MessageBox.Show("Please select an item.")
End If

In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?

What im trying to do is display my details in a listbox then the one that is selected frm the listbox is displayed in the textboxes and when delete button is clicked it is flagged at deleted??? This is what should happen!!:@
I kow there is definitely a problem with this piece of code im setting the index and length to constant numbers so if a different name is clicked it does not work!! is there another way to set this to allow for any length or index position??
CustomerIDTextBox.Text = DisplayCustomersListBox.Text.Substring(0, 4)

So, I need to be able to edit an item that has been selected in a listbox. I need to do so with a button click event. Theoretically, I know how to do this, because I know how to add an item, and how to remove one, and how to insert an item at a specific location.
'Dim strinput As String
'Dim Item As Object
'Dim index As Integer = lstList.Items.IndexOf(item)
'strinput = InputBox("Edit This Item")
'lstList.Items.RemoveAt(lstList.SelectedItem)
'lstList.Items.Insert(index, strinput)
however, this does not work at all. what am I doing wrong??

I am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:
daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")
Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?
