You can pass objects through forms. Here is a small sample project:

VB Code:
  1. 'Form1:

  2. Option Explicit

  3. Private Sub Command1_Click()

  4.     Form2.SetLabel Label1

  5.     Form2.Show vbModal

  6. End Sub

VB Code:
  1. 'Form2:

  2. Option Explicit

  3. Dim MyLabel As Label

  4. Public Sub SetLabel(ByRef TheLabel As Label)

  5.     Set MyLabel = TheLabel

  6. End Sub

  7. Private Sub Command1_Click()

  8.     MyLabel.Caption = MyLabel.Caption & " Changed content"

  9.     Unload Me

  10. End Sub

  11. Private Sub Form_Unload(Cancel As Integer)

  12.     Set MyLabel = Nothing

  13. End Sub

Hope this helps
