I have a series of data that I want to cycle through on  a form.

Each refresh will increment...hit the DB and return the next set of data.  I have this working with a prev/next button.

I want the functionality like powerpoint...if the user hits the space bar, clicks or uses the arrow keys (back/forward).  I want to trap this and do the refresh of the form.

Any thoughts?

sendkeys??

What event can I use?

thanks tons

Just a note...
Powerpoint presentation do not typically require "data entry"

So keys like Tab, Spacebar, mouse clicks  can be used.

In an access form these keys are dedicated...

Sure, ...you can do anything you want.

But how will your app distinguish between a spacebar to refresh, and a space bar between words...?

How about simply using a button?

1. ...and my next question would be why this refresh is needed for each record...?

I mean if you are doing it  with a prev/next button, then you are really doing it on each record.

2. ...If so, then why not just do it on the Current Event of the Form and not ever have to worry about doing it anywhere else?
If Not me.NewRecord then
....'Your "Refresh" code
end if

*IF* the data will be read-only (see Jeff's concerns regarding the distinction of the spacebar for navigation vs data entry.  The arrow keys should be okay regardless), you can use the form's Key-down event to detect the desired keys and move to the next record accordingly:


Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
    On Error Resume Next
    Select Case KeyCode  
        Case vbKeySpace, vbKeyLeft, vbKeyRight ' etc
               docmd.RunCommand acCmdRecordsGoToNext
    End Select
End Sub


You can also use similar code in keydown events of individual controls.

mbizup.

Not sure but I heard that you also have to set the KeyPreview property of the form...?

Not quite sure though...

Yup...

You can either set that statically through the Form's property sheet , under the Events tab or dynamically in the form's open event:

Me.KeyPreview = True
