使用网上比较普遍的vb中使用WindowsAPI实现打开文件对话框代码，

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

调用代码

Sub t()
Dim ofn As OPENFILENAME
Dim rtn As String

ofn.lStructSize = Len (ofn)
ofn.hwndOwner = Application.hWnd
' ofn.hInstance = Application.hInstance
ofn.lpstrFilter = " XML Files (*.xml) " & Chr ( 0 ) & " *.xml " & Chr ( 0 )
ofn.lpstrFile = Space ( 254 )
ofn.nMaxFile = 255
ofn.lpstrFileTitle = Space ( 254 )
ofn.nMaxFileTitle = 255
ofn.lpstrInitialDir = " C: "
ofn.lpstrTitle = " 打开文件 "
ofn.flags = 6148

rtn = GetOpenFileName(ofn)

If rtn <= 1 Then
MsgBox ofn.lpstrFile
Else
MsgBox " Cancel Was Pressed "
End If

End Sub
