Question listbox Choose a Specific item ?

[TMTakas]

Hi vbdotnetforums i have a problem with the listbox items.
i need the application to get a specific item from listbox bellow and display it in a msgbox

there is so many items in the listbox, but i need just the "http://www.google.com/recaptcha/api/challenge?k=6Lfz ......"
Sorry for the inconvenience

And how exactly do you propose to identify the item that you want? You must know something about it, e.g. its index, in order to be able to retrieve it.

thanks, jmcilhinney, the item contains the word "google.com/recaptcha/api"
choose the Element that contains the word "google.com/recaptcha/api" ??

Hi,

You can achieve this by using a For loop to iterate through your ListBox items and then checking for a string that contains what you are looking for. You can then set the SelectedItem property of the ListBox to the string you need. Have a look here:-

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
  For Each myString As String In ListBox1.Items
    If myString.Contains("google.com/recaptcha/api") Then
      ListBox1.SelectedItem = myString
      Exit For
    End If
  Next
End Sub

That said, there seem to be many empty strings in your ListBox so you may find it better to do this string check at the point where you populate your ListBox?

Hope that helps.

Cheers,

Ian
