check boxes in list control

You cannot set the Check from code, and the only way to get the current checked status of a list entry is to monitor all the ItemCheck events.

The Selected property only tells you if the item is selected, not whether its checked or not.

If you want to programatically set the state of the Check box you should use the listview control instead. Slightly more complicated to use, but not too heavy on the old brain cells.

Sorry Gordon... but I think you're mistaking....

If you use a standard listbox and set its Style property to 'Check Box (Value = 1) the Selected property of the listbox will automatically reflect the state of the checkmark. If you set it to True it will be checled, and the checkmark will be unchecked if you set its value to False....
This means that you can set the state of the checkbox programmatically !

To proove you just try the following :

Create a standard exe in VB6, add a listbox List1 to the form and a Command button Command1.
No copy and paste this code in your form's code window and run it....
When its running in debug mode, try to click around on the listbox items by changing the state of the checkboxes... and press the Command1 on each change...


---CODE TO COPY

Private Sub Command1_Click()

    Dim strSelected As String
    Dim i As Integer
   
    For i = 0 To (List1.ListCount - 1)

        If List1.Selected(i) Then
            strSelected = strSelected & "Item Selected = " & CStr(i) & vbCrLf
        End If

    Next i

    Debug.Print strSelected

End Sub

Private Sub Form_Load()
    'Just create some entries in the listbox to have it filled...
    List1.AddItem "Checked"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
    List1.AddItem "Checked2"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
    List1.AddItem "Checked"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
    List1.AddItem "Checked2"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
    List1.AddItem "Checked"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
    List1.AddItem "Checked2"
    List1.Selected(List1.NewIndex) = True
    List1.AddItem "Not Checked"
   

End Sub

---- END OF CODE

Try this and you'll see that it works...

Well, my mistake, and boy am I pissed off. So many things could have been so much simpler.
