[AccessD] Framework Discussion - Disconnected labels

  The SQL behind the form did not include all of fields referenced on the
form so and when you selected a company name, you would get ?NAME error in
the fields.


>And the class "dclsCtlTextBox" includes Reference to the label "mlbl"
variable in the exit and enter events that are not being Initialized (set).

>This was to demo the disconnected label.  I set an On Error Resume Next in

  Not in the version I downloaded. any movement in any field would produce a
Object not set error

>This stuff will come back out for V5, it was just a demo of what is
>possible.

 Real cool stuff!!!

John,
 Your demo has some problems.. The recordset for the "frmPeopleV4" form
doesn't include displayed fields.  And the class "dclsCtlTextBox" includes
Reference to the label "mlbl" variable in the exit and enter events that are
not being Initialized (set). I presumed that these references are in error.
I Commented them out, fix the recordset and all seems to work like a
charm.....

BTW it is possible to add controls to a control's control collection.  Thus
you can "TELL" a control in a continuous form that a label in the form's
header belongs to it.  I add a function to the class which assigns a label
out on the form to that control:

'
'Connects a label to a combo - used for continuous forms where the label is
in the header etc.
'
Function ConnectLabel(llbl As Label)
On Error GoTo Err_ConnectLabel
    Set mlbl = llbl
Exit_ConnectLabel:
Exit Function
Err_ConnectLabel:
        MsgBox Err.Description, , "Error in Function
dclsCtlTextBox.ConnectLabel"
        Resume Exit_ConnectLabel
    Resume 0    '.FOR TROUBLESHOOTING
End Function

Then, strictly for demo purposes I set and reset the label's backcolor in
the text boxes OnEnter and OnExit:

'
'These are the event stubs for the control's OnEnter and OnExit events
'
Private Sub mtxt_Enter()
    mlngBackColorOrig = mtxt.BackColor  'When we enter the text box, save
the original back color
    mtxt.BackColor = mclngBackColor     'Set the back color to our favorite
color
    mlbl.BackColor = 16744448
    mlbl.BackStyle = 1

End Sub

Private Sub mtxt_Exit(Cancel As Integer)
    mtxt.BackColor = mlngBackColorOrig  'When we exit the control, set the
back color back to the original color
    mlbl.BackStyle = 0
End Sub

In the form's Open event, after initializing the framework I call this
method and pass in a lable:

Public fdclsFrm As dclsFrm

Private Sub Form_Open(Cancel As Integer)
    Set fdclsFrm = New dclsFrm
    fdclsFrm.Init Me, Me
    With fdclsFrm.colClasses
        .item("txtCode").ConnectLabel lblCode
        .item("txtName").ConnectLabel lblName
    End With
End Sub

To see this functionality open the lfrmState and tab through the two
columns.  Again, this isn't particularly useful in this instance but it
might be a helpful indicator of cursor movement or state of a control and
again demonstrates that a disconnected label can be added to a control's
control class.
