ListBox read item on double click

[jdwyer05]

Hi,

I have a list box where I am reading information from a MS Access Database.
The list box populates when the form is loaded. However, sometimes the information is wider than the list box. I have added scroll bars so user can see the information. However, It would be great if they didn't need to scroll.

I've read that listboxes cannot wrap text so, is there a way to use a double click event on a item to readthat line from the list box and display it in another text field so i can use the mutliline function? Or even better after the item is double clicked a pop up form will appear with the item

Thanks in advance, i hope that made sense

hi

this might be a solution

 
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
 
Private Const LB_ITEMFROMPOINT = &H1A9
Dim ndx As Long
 
Public Function ListBoxHit(ListBox As ListBox, ByVal X As Single, ByVal Y As Single) As Long
    ndx = SendMessage(List1.hWnd, LB_ITEMFROMPOINT, 0, (Y \ Screen.TwipsPerPixelY) * 65536 + (X \ Screen.TwipsPerPixelX))
    If (ndx And &H10000) = &H10000 Then
        ListBoxHit = -1
    Else
        ListBoxHit = ndx
    End If
End Function
 
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Label1.Visible = False
End Sub
 
Private Sub List1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 2 Then
  ndx = ListBoxHit(List1, X, Y)
  If Not ndx = -1 Then List1.Selected(ndx) = True
  With Label1
  .Move List1.Left + List1.Width, List1.Top + Y - 60
  .Caption = " " & List1.List(ndx) & " "
  .Visible = True
  End With
Else
Label1.Visible = False
End If
End Sub
 
 
 

the listbox = List1
the label=Label1
create:
visible=false
backstyle=opaque
autosize=true
borderstyle=fixed single
backcolor= any color

click with right mouse on a list.item will trigger the label to pop-up

albertw,

Im still having problems reading the events, the code you provided does implement the click event. However, it will only read the first item int he list box.
for example:

if i have a list with the records 1,2,3,4,5 and i click on 5 it will still display the record for number 1.

It looks like ndx is not updating with the correct selected record. B/c if you just enter an integer value into the .Caption = " " & List1.List(ndx) & " " it will display the record corresponding to that value. So it seems to be that ndx is constantly remaining the value 0.
