this is a good starting point to what you're looking to do:

     ‘Determine if form already exists 
  Dim frmTest As Form 
  Dim blnFound As Boolean = False 
   
  ‘Does form already exist? 
  For Each frmTest In Me.MdiChildren 
     With frmTest 
  	  If .Name = “frmForm” Then 
  		 .Activate()   ‘Activate previous instance 
  		 blnFound = True 
  	  End If 
     End With 
  Next 
  If blnFound = False Then 
     Dim frmForm As New frmForm 
     With frmForm 
  	  .MdiParent = Me 
  	  .Show() 
     End With 
  End If[font=&quot] [/font]

basically what this does is looks through all of the child forms looking for a specific form (you can add a check for something entered in the tag property too) anywho if the form is found then it's activated (given focus) if not, then one is created
