I need to be able to re-initialize a form without exiting and restarting the form.
What's the best way to accomplish this? I haven't found anything that really addresses this. Or did I miss something?

Thanks,
Karen

...explain what you are trying to do? Why do you need to re-initialize the form? Is what you need to do something that could be achieved by using Static members?

Sorry about that ...
I created a form to use to scan our incoming equipment.
I would like to be able to have a button that would, in effect, close and re-load the form to re-initialize all the values, but without the user seeing the close and re-load.

More detail:
I have four combo lookup boxes that get filled based on previous values selected.
There are also two other combo lookup boxes that keep the same values the whole time.
The data grid view gets populated with those values (but the columns are hidden) plus the serial number from the phone.
The user needs to be able to change the values in the lookup boxes, and keep scanning, without losing much time. (The user is generally scanning 7-10 thousand phones at a time.)
A quick save, re-select values, and continue.

I hope that helps you help me.

I think I've figured out how to do what I want.

I created a Reset button on my form.

The Click event is supposed to cause the data in the data grid to be saved.

Then I want it to go to the Load function for the form.

I added the Click event for the button to the Handles clause on the Load event for the form.

When I tested, the Click event on the Reset button was handled first, But the Load event was not handled.
Is there a way to make this happen? What am I missing?

You might be making this more difficult than it needs to be. Try this approach:

1.) Take the code that is currently in your form_load event and create a procedure from it. Remove everything from your form_load event except a call to your new procedure.

2.) Take the code that is currently handling the data/save tasks in your button_click event and create a procedure from it. Remove everything from the button_click event except a call to your new data/save procedure and your procedure from #1 above.

As a general rule I implement procedures/functions from event code (form_load, button_click, etc.) rather than writing code directly into those events. That way if I need to reuse a portion of code all I have to do is call that procedure again.

Clear as mud? Here is an example:
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Call Me.subLoadData() '* This procedure clears and resets data.
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Call Me.subSaveData() '* I'm saving the data here.
        Call Me.subLoadData() '* I'm resetting the form here.
    End Sub

Nice, Earl—nice and compact.

This is the code contained in my load and click events.
At this point, there is nothing in the load event to make a procedure.

I thoroughly understand what you are trying to show me and I agree and I like the way you explained it (you forgot to mention the Mississippi River mud, though).

I'm just not sure where to go from here.

Karen

Ok. Regardless if you have any initialization going on in the Form_Load event, the methodology is the same.

Private Sub resetFormValues()
'Set all form values to their defaults
End Sub

Private Sub btnReset_Click(ByVal sender as System.Object, ByVal e as System.EventArgs) Handles btnReset.Click
 Me.EquipmentTableAdapter.Update(Me.APC_WirelessDat aSet.Equipment)
 Me.resetFormValues()
End Sub

hth.

Try this:
    Private Sub btnReset_Click(ByVal sender As System.Object, _
            ByVal e As System.EventArgs) Handles btnReset.Click
        ' save work done to this point
        Me.EquipmentTableAdapter.Update(Me.APC_WirelessDat aSet.Equipment)

        '* This should refill your table adapter and reset/rebind
        '* any controls on your form. You may need to manually
        '* clear/reset any unbound controls.

        Me.EquipmentTableAdapter.ClearBeforeFill = True
        Me.EquipmentTableAdapter.Fill(Me.APC_WirelessDataS et.Equipment)


        ' give focus to Manufacturer combo button to start next set of scans
    End Sub

Thanks to Earl and Doug for your help.

Now I'm trying to figure out how to clear a datasource from a combo box.

This works fine during the initial load of the form.
This is its complaint now:
System.InvalidCastException was unhandled
  Message="Overload resolution failed because no Public '=' can be called with these arguments:
    'Public Shared Operator =(a As String, b As String) As Boolean':
        Argument matching parameter 'a' cannot convert from 'DataTable' to 'String'."

I did what I thought I understood the information in Help said, but obviously I misunderstood.
