Hola, te paso una idea:
pone un Msflexgrid1 y un text1
Código:
Private Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long
Private Sub Form_Load()
SetParent Text1.hWnd, MSFlexGrid1.hWnd
With Text1
.Top = 0
.Left = 0
.Width = MSFlexGrid1.Width
.Height = 50
End With
End Sub
