hello group,

I have an unbound form, with a list box (lstDispmain) on it. the primary key
tothe list box is controlnumberID.

I want to be able to double click a single entry on the list box and open up
that record. how can i do this by referring to the controlnumberID in the
listbox, and opening that form?

the code below opens a blank record.

thanks in advance

lee

CODE:

Private Sub cmdOpenMission_Click()
On Error GoTo Err_cmdOpenMission_Click

Dim stDocName As String
Dim stLinkCriteria As String

stDocName = "frmActivity"

stLinkCriteria = "[ControlNumberID]=" & "'" & Me![lstDispMain] & "'"
DoCmd.OpenForm stDocName, , , stLinkCriteria

Exit_cmdOpenMission_Click:
Exit Sub

Err_cmdOpenMission_Click:
MsgBox Err.Description
Resume Exit_cmdOpenMission_Click

End Sub
 
From what i can see you are trying to set the criteria
through the code window but not the recordset.

I would go to the forms record source and set the criteria
there.

The criteria would simply be the listbox's control number
ID. then on click or double click requery the subform.

DoCmd.Requery "Forms!MainForm!SubForm"

I hope that helps.
 
Hi Lee

Make sure that the BoundColumn property of your listbox is set to the column
from the RowSource which contains the ControlNumberID. (1 indicates the
first column, etc, unlike the .Column( ) property, which is zero-based)

Also, is ControlNumberID a numeric field? If so, then get rid of the single
quotes:
stLinkCriteria = "[ControlNumberID]=" & Me![lstDispMain]

If it still doesn't work, set a breakpoint on the DoCmd.OpenForm line and
examine the value of stLinkCriteria to see if anything hits you between the
eyes :-)
 
It works great. i was number field and i set the bound column to 1..

thanks

(this newsgroup is awesome!)
