Here is some sample code from the Microsoft KB, source.

Option Explicit

Private Declare Function GetOpenFileName Lib "comdlg32.dll" Alias _
         "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long

Private 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

Private Sub Command1_Click()
    Dim OpenFile As OPENFILENAME
    Dim lReturn As Long
    Dim sFilter As String

    OpenFile.lStructSize = Len(OpenFile)
    OpenFile.hwndOwner = Form1.hwnd
    OpenFile.hInstance = App.hInstance
    sFilter = "Batch Files (*.bat)" & Chr(0) & "*.BAT" & Chr(0)
    OpenFile.lpstrFilter = sFilter
    OpenFile.nFilterIndex = 1
    OpenFile.lpstrFile = String(257, 0)
    OpenFile.nMaxFile = Len(OpenFile.lpstrFile) - 1
    OpenFile.lpstrFileTitle = OpenFile.lpstrFile
    OpenFile.nMaxFileTitle = OpenFile.nMaxFile
    OpenFile.lpstrInitialDir = "C:\"
    OpenFile.lpstrTitle = "Use the Comdlg API not the OCX"
    OpenFile.flags = 0
    lReturn = GetOpenFileName(OpenFile)
    If lReturn = 0 Then
        MsgBox "The User pressed the Cancel Button"
    Else
        MsgBox "The user Chose " & Trim(OpenFile.lpstrFile)
    End If
End Sub
