Lock screen or just outlook while performing VBA script

I have created a script in VBA in Outlook, that move mails to our DMS. The macro takes a while around 2-3 seconds per e-mail. I need somehow to prevent the user from clicking around in outlook while the macro is running. I tried displaying a form with the command FrmInfoFlyt.Show (vbModeless), but that doesn't help. Any ideas ?

tested working, alt-ctl-delete cancels the lock.
Public Declare Function BlockInput Lib "USER32.dll" (ByVal fBlockIt As Long) As Long

Private Sub ImpData_Click()
On Error GoTo Err_ImpData_Click
Dim intCounter As Long

BlockInput True
For intCounter = 1 To 2147000000
  'take a nap!
BlockInput False
DoCmd.Hourglass False
  Exit Sub
  BlockInput False
  DoCmd.Hourglass False
    MsgBox Err.Description, vbExclamation, "Error in Pic Names"
