Try this. Note: This will work if the document is open, but NOT minimized, but rather, running in the background. Also, you must know what the caption of the document is.
VB Code:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SetForegroundWindow Lib "user32" (ByVal hwnd As Long) As Long
Private Sub Command1_Click()
Dim WinWnd As Long
Dim ShowWin As Long
WinWnd = FindWindow(vbNullString, "Employee Appraisal Form.doc - Microsoft Word")
If WinWnd = 0 Then
MsgBox "Document not found"
Else
ShowWin = SetForegroundWindow(WinWnd)
End If
End Sub
