Listbox Search!?

ok, how do i make it so that i have a listbox and a textbox and my listbox is filled with names (Anthony, Alex, Brad, Anthony, Anthony) and when i type a name in the textbox, it will only show that name in the listbox and will remove the rest of the other names. ex: If i type Anthony in the textbox then in the listbox all that will show is Anthony
Anthony
Anthony
and Brad and Alex will not show. Does anyone know how to do this its a search method its in some software programs....please help! Thank you.

Try doing a search for "Autocomplete"

I found one of my old threads that worked here

This will get you started. :D

Your link is for a ListView. The OP is asking about a ListBox, for which I would use something like

vb Code:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, _
ByVal wMsg As Long, ByVal wParam As Long, lparam As Any) As Long 
 
Private Const LB_FINDSTRING = &H18F   
Private Const LB_FINDSTRINGEXACT = &H1A2
 
Private Sub txtSearch_Change()
List1.ListIndex = SendMessage(List1.hwnd, LB_FINDSTRING, -1,  ByVal CStr(Text1.Text)) 
End Sub

To make it autocomplete you will want to use the Change event of the textbox perhaps instead of a command button.

Good point. :D

Changed.

That is assuming, the listbox has already items on it. Try it out and see what fits your program best.

A listbox and a combobox use almost the same exact code for this. Just use the different constant declarations. Different values but named similar CB_ or LB_

Private Const LB_FINDSTRING As Long = &H18F
Private Const LB_FINDSTRINGEXACT As Long = &H1A2

Private Const CB_FINDSTRING As Long = &H14C
Private Const CB_FINDSTRINGEXACT As Long = &H158

How did a combo box make it into the question? :confused:

Because I posted it. :p

Just pointing out a useless fact.
