Search Array in a Array ?

ilker cam

Hello,

i have got two listboxs, there are listbox1 and listbox2

forex.

listbox1.items are = (teacher,school,pen,pencil,germany,asia,asia1,asia2,asia3)listbox2.items are =(asia,pen)
i have to search the listbox2 items in listbox1 and if listbox1 contains the words from listbox2. it must be deleted.
result might be load to listbox3
and the items would be (teacher,school,germany) of course...

and i have got one more questions. i got the list from a text box, but the list is over then 18mb and, i have to wait too much, is there any ways to resolve this waiting prblem...

Thanks

hi..

For searching a items in array you dont need to use any loop for searching the items,instead of that you have to use this method to search item in array...http://vbdotnetaddict.blogspot.com/2011/02/search-items-in-array-string-without.html

H ilker cam,

Here is your code for aspx:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

    Untitled Page

























vb.net code

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        For d As Integer = 0 To list2.Items.Count - 1
            Dim f As Integer = 0
            While f < list1.Items.Count
                If list1.Items(f).Text.Contains(list2.Items(d).Text) Then
                    list1.Items.RemoveAt(f)
                    f = f - 1
                End If
                f = f + 1
            End While
        Next d

        For g As Integer = 0 To list1.Items.Count - 1
            list3.Items.Add(list1.Items(g))
        Next g
    End Sub
End Class
