窗体上放一个编辑框和按钮
Private Sub Command1_Click()
Dim ofn As OPENFILENAME
Dim strRtn As String
ofn.lStructSize = Len(ofn)
ofn.hwndOwner = Me.hwnd
ofn.hInstance = App.hInstance
ofn.lpstrFilter = "所有文件"
ofn.lpstrFile = Space(254)
ofn.nMaxFile = 255
ofn.lpstrFileTitle = Space(254)
ofn.nMaxFileTitle = 255
ofn.lpstrInitialDir = App.Path
ofn.lpstrTitle = "打开文件"
ofn.flags = 6148
rtn = GetOpenFileName(ofn)
If rtn >= 1 Then
Text1.Text = ofn.lpstrFile
Else
Text1.Text = "Cancel Was Pressed"
End If
End Sub
