Setting focus to another open app?

From my vb app how would I get a handle to an **open** word document and set focus to it??

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
