在窗体上添加一个按钮 commandbutton1
加入如下代码:

Private Sub Command1_Click()
Dim ofn As OPENFILENAME
Dim rtn As String
ofn.lStructSize = Len(ofn)
ofn.hwndOwner = Me.hWnd
ofn.hInstance = App.hInstance
ofn.lpstrFilter = "文本文档(*.txt)" & Chr(0) & "*.txt" & Chr(0) & "所有文件" & Chr(0) & "*.*" & Chr(0)
ofn.lpstrFile = Space(254)
ofn.nMaxFile = 255
ofn.lpstrFileTitle = Space(254)
ofn.nMaxFileTitle = 255
ofn.lpstrInitialDir = App.Path
ofn.flags = 6148
rtn = GetOpenFileName(ofn)
If rtn >= 1 Then
Shell "notepad.exe " & ofn.lpstrFile, vbNormalFocus
End If
End Sub
