Pada kesempatan kali ini Admin akan berbagi sebuah source code yang sangat sederhana yaitu bagaiamana cara membuat browse folder atau folder view menggunakan visual basic 6.0. Salah satu kegunaan browse folder salah satu diantaranya adalah untuk tujuan path backup database, menampilkan data data di path tertentu dan masih banyak lainnya fungsi dari browse folder ini.
Berikut dibawah ini adalah gambar dari hasil pengkodean browse folder dengan menggunakan vb6 :

| Output |
Bagi Anda yang penasaran bagaimana cara membuatnya, ikuti langkah-langkah dibawah ini :
1. Buka Form VB6 Standar Exe
2. Pada Form1 tanamkan 1 Label, 1 Textbox dan 1 Commandbutton
3. Desainlah Form seperti gambar dibawah ini :

4. Tambahkan 1 buah Module pada project Anda, pada jendela Module ketik kode dibawah ini :
Private Type BrowseInfo
hwndOwner As Long
pIDLRoot As Long
pszDisplayName As Long
lpszTitle As Long
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
Private Const BIF_BROWSEFORCOMPUTER = &H1000
Private Const BIF_BROWSEFORPRINTER = &H2000
Private Const BIF_BROWSEINCLUDEFILES = &H4000
Private Const BIF_DONTGOBELOWDOMAIN = &H2
Private Const BIF_EDITBOX = &H10
Private Const BIF_NEWDIALOGSTYLE = &H40
Private Const BIF_RETURNFSANCESTORS = &H8
Private Const BIF_RETURNONLYFSDIRS = &H1
Private Const BIF_STATUSTEXT = &H4
Private Const BIF_USENEWUI = (BIF_NEWDIALOGSTYLE Or BIF_EDITBOX)
Private Const MAX_PATH = 260
Private Declare Sub CoTaskMemFree Lib "ole32.dll" _
(ByVal hMem As Long)
Private Declare Function lstrcat Lib "kernel32" _
Alias "lstrcatA" (ByVal lpString1 As String, _
ByVal lpString2 As String) As Long
Private Declare Function SHBrowseForFolder Lib "shell32" _
(lpBI As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32" _
(ByVal pidList As Long, ByVal lpBuffer As String) As Long
Const CSIDL_DESKTOP = &H0
Const CSIDL_PROGRAMS = &H2
Const CSIDL_CONTROLS = &H3
Const CSIDL_PRINTERS = &H4
Const CSIDL_PERSONAL = &H5
Const CSIDL_FAVORITES = &H6
Const CSIDL_STARTUP = &H7
Const CSIDL_RECENT = &H8
Const CSIDL_SENDTO = &H9
Const CSIDL_BITBUCKET = &HA
Const CSIDL_STARTMENU = &HB
Const CSIDL_DESKTOPDIRECTORY = &H10
Const CSIDL_DRIVES = &H11
Const CSIDL_NETWORK = &H12
Const CSIDL_NETHOOD = &H13
Const CSIDL_FONTS = &H14
Const CSIDL_TEMPLATES = &H15
Const CSIDL_COMMON_STARTMENU = &H16
Const CSIDL_COMMON_PROGRAMS = &H17
Const CSIDL_COMMON_STARTUP = &H18
Const CSIDL_COMMON_DESKTOPDIRECTORY = &H19
Const CSIDL_APPDATA = &H1A
Const CSIDL_PRINTHOOD = &H1B
Private Type SHITEMID
Cb As Long
AbID As Byte
End Type
Private Type ITEMIDLIST
Mkid As SHITEMID
End Type
Private Declare Function SHGetSpecialFolderLocation Lib "shell32.dll" (ByVal hwndOwner As Long, ByVal nFolder As Long, pidl As ITEMIDLIST) As Long
Private Declare Function OleInitialize Lib "ole32.dll" (lp As Any) As Long
Private Declare Sub OleUninitialize Lib "ole32" ()
Public Function fBrowseForFolder(hwndOwner As Long, sPrompt As String) As String
Dim iNull As Long
Dim lpIDList As Long
Dim lResult As Long
Dim sPath As String
Dim sPath1 As String
Dim udtBI As BrowseInfo
Dim IDL As ITEMIDLIST
'
sPath1 = fGetSpecialFolder(CSIDL_DESKTOP, IDL)
Call OleInitialize(ByVal 0&)
With udtBI
.pIDLRoot = IDL.Mkid.Cb
.hwndOwner = hwndOwner
.lpszTitle = lstrcat(sPrompt, "")
.ulFlags = BIF_RETURNONLYFSDIRS + BIF_USENEWUI
End With
lpIDList = SHBrowseForFolder(udtBI)
If lpIDList Then
sPath = String$(MAX_PATH, 0)
lResult = SHGetPathFromIDList(lpIDList, sPath)
Call CoTaskMemFree(lpIDList)
iNull = InStr(sPath, vbNullChar)
If iNull Then sPath = Left$(sPath, iNull - 1)
End If
Call OleUninitialize
fBrowseForFolder = sPath
End Function
Private Function fGetSpecialFolder(CSIDL As Long, IDL As ITEMIDLIST) As String
Dim sPath As String
If SHGetSpecialFolderLocation(hWnd, CSIDL, IDL) = 0 Then
sPath = Space$(MAX_PATH)
If SHGetPathFromIDList(ByVal IDL.Mkid.Cb, ByVal sPath) Then
fGetSpecialFolder = Left$(sPath, InStr(sPath, vbNullChar) - 1) & "\"
End If
End If
End Function
5. Lalu tambahkan kode dibawah ini di bagian CommandButton
Private Sub Command1_Click()
Dim sStrPathBackup As String
sStrPathBackup = fBrowseForFolder(hWnd, "Pilih Direktori untuk Backup database")
If sStrPathBackup <> vbNullString Then
Text1.Text = sStrPathBackup
End If
End Sub
Setelah kode selesai dibuat jalankan project Anda, jika tidak ada error maka hasilnya akan tampak seperti gambar diatas pada artikel ini.
Demikian artikel kali ini tentang cara membuat browse folder atau folder view menggunakan visual basic 6.0.Semoga artikel ini bermanfaat buat kita semua.Amin....
Selamat mencoba semoga berhasil
