If you want to use 'Find Files' standard dialog, in your programs you can choose between the following four methods.

  • Using DDE: it's needed an label control, even invisible.
  • Private Sub Command1_Click()
        With Label1
        .LinkTopic = "Folders|AppProperties"
        .LinkMode = vbLinkManual
        .LinkExecute "[OpenFindFile(,)]"
      End With
    End Sub
    
    Private Sub Form_Load()
      Label1.Visible = False
      Command1.Caption = "Find File (1)..."
      Me.Caption = "Find File (1)"
    End Sub
    
  • Using keybd_event API function to simulate Win + 'F':
  • Private Declare Sub keybd_event Lib "user32" _
        (ByVal bVk As Byte, _
        ByVal bScan As Byte, _
        ByVal dwFlags As Long, _
        ByVal dwExtraInfo As Long)
    '
    Private Const VK_LWIN = &H5B
    Private Const KEYEVENTF_KEYUP = &H2
    Private Const VK_APPS = &H5D
    '
    Private Sub Command1_Click()
        Call keybd_event(VK_LWIN, 0, 0, 0)
        Call keybd_event(&H46, 0, 0, 0)       'F
        Call keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0)
    End Sub
    '
    Private Sub Form_Load()
      Command1.Caption = "Find File (2)..."
      Me.Caption = "Find File (2)"
    End Sub
    
  • Using MS Q183903 (http://support.microsoft.com/support/kb/articles/q183/9/03.asp)
  • Private Declare Function ShellExecute Lib "shell32.dll" _
        Alias "ShellExecuteA" _
        (ByVal hwnd As Long, _ 
         ByVal lpOperation As String, _
         ByVal lpFile As String, _
         ByVal lpParameters As String, _
         ByVal lpDirectory As String, _
         ByVal nShowCmd As Long) As Long
    
    Private Const SW_SHOWNORMAL = 1
    Private Const SW_SHOWMINIMIZED = 2
    Private Const SW_SHOWMAXIMIZED = 3
    Private Const SW_SHOW = 5
    Private Const SW_MINIMIZE = 6
    Private Const SW_SHOWMINNOACTIVE = 7
    Private Const SW_SHOWNA = 8
    Private Const SW_RESTORE = 9
    Private Const SW_SHOWDEFAULT = 10
    
    Private Sub Command1_Click()
       Call ShellExecute(Me.hwnd, _
          "find", _
          Dir1.Path, _
          vbNullString, _
          vbNullString, _
          SW_SHOWNORMAL)
    End Sub
    
    Private Sub Drive1_Change()
       Dir1.Path = Drive1.Drive
    End Sub
    
    Private Sub Form_Load()
       Command1.Caption = "Find File (3)..."
    End Sub
    
  • Using undocumented function SHFindFiles and SHSimpleIDListFromPath from Shell32.dll:
  • Private Declare Function SHFindFiles Lib "Shell32" _
        Alias "#90" _
        (pidlRoot As Long, pidlSavedSearch As Long) As Long
    Private Declare Function SHSimpleIDListFromPath Lib _
        "Shell32" Alias "#162" _
        (ByVal lpszPath As String) As Long
    '
    Private Sub Command1_Click()
      Dim l As Long
      l = SHSimpleIDListFromPath(Dir1.Path)
      SHFindFiles ByVal l, ByVal 0
    End Sub
    
    Private Sub Drive1_Change()
      Dir1.Path = Drive1.Drive
    End Sub
    
    Private Sub Form_Load()
      Command1.Caption = "Find File (4)..."
      Me.Caption = "Find File (4)"
    End Sub
    

For the last two methods you need to add a DriveListBox and a DirListBox
control. With this methods you can give the start path for searching.
