下面介绍如何使用Window API显示一个“打开”的对话框:把下面的内容放到一个模块内: Declare Function GetOpenFileName Lib "comdlg32.dll" Alias _ "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long
Type OPENFILENAME lStructSize As Long hwndOwner As Long hInstance As Long lpstrFilter As String lpstrCustomFilter As String nMaxCustFilter As Long nFilterIndex As Long lpstrFile As String nMaxFile As Long lpstrFileTitle As String nMaxFileTitle As Long lpstrInitialDir As String lpstrTitle As String flags As Long nFileOffset As Integer nFileExtension As Integer lpstrDefExt As String lCustData As Long lpfnHook As Long lpTemplateName As String End Type在调用对话框的按钮的click事件输入下面代码:Private Sub FileOpen_Click() Dim ofn As OPENFILENAME Dim rtn 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 msgbox "你打开的是:" & ofn.lpstrFile Else msgbox "按了取消" End If End Sub
CommonDialog可以用CreateObject创建的.Set xx = CreateObject("MSComDlg.CommonDialog") xx.showopen
mymsg = MsgBox("对话框内容", vbOKCancel, "对话框标题")
