Steps to replace the Common Dialog functionality

Microsoft Office Access 2003

  1. In Access, open the sample database that is named Northwind.mdb.

    Note The Northwind.mdb database for Access 2003 is typically located in the C:\Program Files\Microsoft Office\OFFICE11\Samples folder.
  2. Under Objects in the Northwind Database window, click Forms.
  3. In the Database window toolbar, click New.
  4. In the New Form dialog box, click Design View, and then click OK.
  5. Add a text box to Form1, right-click the text box, and then click Properties.
  6. Click the All tab, click Name, type Text1, and then close the Properties dialog box.
  7. Right-click the label control that is associated with the Text1 text box, click Properties, and then click the All tab.
  8. Click Caption, type Text1, and then close the Properties dialog box.
  9. Add a command button to Form1, right-click the command button, click Properties, click Name, type Command1, click Caption, and then type Command1.
  10. Click the Event tab, click [Event Procedure] in the On Click list, and then click the ellipsis button to start the Microsoft Visual Basic Editor.
  11. Modify the code in the Command1_Click procedure to the following:
    Private Sub Command1_Click()
        Me!Text1 = LaunchCD(Me)
    End Sub
  12. On the Insert menu, click Module, and then insert the following code into Module1:
    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
    
    Function LaunchCD(strform As Form) As String
        Dim OpenFile As OPENFILENAME
        Dim lReturn As Long
        Dim sFilter As String
        OpenFile.lStructSize = Len(OpenFile)
        OpenFile.hwndOwner = strform.hwnd
        sFilter = "All Files (*.*)" & Chr(0) & "*.*" & Chr(0) & _
          "JPEG Files (*.JPG)" & Chr(0) & "*.JPG" & 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 = "Select a file using the Common Dialog DLL"
        OpenFile.flags = 0
        lReturn = GetOpenFileName(OpenFile)
            If lReturn = 0 Then
                MsgBox "A file was not selected!", vbInformation, _ 
                  "Select a file using the Common Dialog DLL"
             Else
                LaunchCD = Trim(Left(OpenFile.lpstrFile, InStr(1, OpenFile.lpstrFile, vbNullChar) - 1)) 
             End If
    End Function
    
  13. On the Debug menu, click Compile Northwind, and then close the Visual Basic Editor.
  14. On the View menu, click Form View.
  15. Click Command1, and then click a file in the window that opens.

    The path of the file appears in the Text1 text box.

        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 = "Select a file using the Common Dialog DLL"
        OpenFile.flags = 0
