So, das habe ich schon versprochen:
1. Schritt:
Erstelle ein neues BAS Module und kopiere folgenden Code ins Module
| Visual Basic: |
Option Explicit
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
'Browsing type.
Public Enum BrowseType
BrowseForFolders = &H1
BrowseForComputers = &H1000
BrowseForPrinters = &H2000
BrowseForEverything = &H4000
End Enum
'Folder Type
Public Enum FolderType
CSIDL_BITBUCKET = 10
CSIDL_CONTROLS = 3
CSIDL_DESKTOP = 0
CSIDL_DRIVES = 17
CSIDL_FONTS = 20
CSIDL_NETHOOD = 18
CSIDL_NETWORK = 19
CSIDL_PERSONAL = 5
CSIDL_PRINTERS = 4
CSIDL_PROGRAMS = 2
CSIDL_RECENT = 8
CSIDL_SENDTO = 9
CSIDL_STARTMENU = 11
End Enum
Private Const MAX_PATH = 260
Private Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long)
Private Declare Function lstrcat Lib "kernel32.dll" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long
Private Declare Function SHBrowseForFolder Lib "shell32.dll" (lpbi As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" (ByVal pidList As Long, ByVal lpBuffer As String) As Long
Private Declare Function SHGetSpecialFolderLocation Lib "shell32.dll" (ByVal hWndOwner As Long, ByVal nFolder As Long, ListId As Long) As Long
Public Function BrowseFolders(hWndOwner As Long, sMessage As String, Browse As BrowseType, ByVal RootFolder As FolderType) As String
Dim Nullpos As Integer
Dim lpIDList As Long
Dim res As Long
Dim sPath As String
Dim BInfo As BrowseInfo
Dim RootID As Long
SHGetSpecialFolderLocation hWndOwner, RootFolder, RootID
BInfo.hWndOwner = hWndOwner
BInfo.lpszTitle = lstrcat(sMessage, "")
BInfo.ulFlags = Browse
If RootID <> 0 Then BInfo.pIDLRoot = RootID
lpIDList = SHBrowseForFolder(BInfo)
If lpIDList <> 0 Then
sPath = String(MAX_PATH, 0)
res = SHGetPathFromIDList(lpIDList, sPath)
Call CoTaskMemFree(lpIDList)
Nullpos = InStr(sPath, vbNullChar)
If Nullpos <> 0 Then
sPath = Left(sPath, Nullpos - 1)
End If
End If
BrowseFolders = sPath
End Function
|
BrowseFolders zeigt ein Fenster, das alle Ordner deines Rechners anzeigt, beim Auswählen wird den Pfad zurückgegeben.
bsp:
| Visual Basic: |
Option Explicit
Private Sub Form_Load()
MsgBox BrowseFolders(hWnd, "Select a Folder", BrowseForFolders, CSIDL_DESKTOP)
Unload Me
End Sub
