listbox in vb.net

[Anusubha V G]

I need to add the item and value in the list box. I add this using strtext and strvalue respectively. But the strvalue i need to add is a string. so that the value when adding cannot get duplicated. How can i add string value to strvalue I am taking this values from two textboxes My coding is as follows.... Dim i As Integer Dim item As New Item For i = 0 To ListBox1.Items.Count - 1 item = ListBox1.Items(i) If TextBox1.Text = item.strValue Then MsgBox("Already you have added this link", MsgBoxStyle.Information, "Knowledge Base") Exit Sub End If Next item.strText = Textbox2.Text item.strValue = TextBox1.Text lstLinks.Items.Add(item) txtWebLinkDescriptions.Text = "" txtWebLinks.Text = "" It shows that the string value cannot be bind to integer value.... May u help me to solve these please.... Thanks in advanvce........

Hi, I think this code will help you... Dim i As Integer For i = 0 To ListBox1.Items.Count - 1 If ListBox1.Items(I).Tostring = TextBox1.Text Then MsgBox("Already you have added this link", MsgBoxStyle.Information, "Knowledge Base") Exit Sub End If Next lstLinks.Items.Add(TextBox1.Text)

Thanks, Nanda

The easy way is to build a dictionary where the key is the strValue, or just a list of strings, even. Do a search, if the value is in there, then it's been added already.
