Hi chiph ,sorry that I still new in VB.NET. I dont quite nederstand your coding .
What is Myitem , what is someproperty ? could write the code completely (with declaration)

For example ,I want to search the employee no(textbox) exists in the listbox ? how should i do that ?

Thank you

OK, here's a one-liner for you:

iIndex = MyListBox.FindString("Employee 34")

Here's the online help about this method:

http://msdn.microsoft.com/library/d...mwindowsformslistboxclassfindstringtopic1.asp

What this method does is locate in your ListBox (the MyListBox object) the first string that starts with the supplied string ("Employee 34" in this example -- you'd use a string variable in your actual code).

If it finds a match, iIndex will contain the index of the item. Otherwise it will contain ListBox.NoMatches (a special value supplied by the ListBox class).
