List of every drives

[guile]

Hi everyone,
how could I get all the drives of my computer. In fact I know how to get physical drive (A:, C: ...) but I would like to find the folders like "Desktop", "My Computer", "Network neightbourghhood" "Recycled" in fact the special folders you can see in the combobox of word (file->open)

Hi,

You can make use of FileSystem object.

Sample code:
============
Dim filesys, drv, drvcoll, drvlist, vol
Set filesys = CreateObject("Scripting.FileSystemObject")
Set drvcoll = filesys.Drives
For Each drv In drvcoll
drvlist = drvlist & drv.DriveLetter
If drv.IsReady Then
vol = drv.VolumeName
End If
If vol <> "" Then drvlist = drvlist & " ShareName: " & vol
drvlist = drvlist & Chr(10)
Next
MsgBox drvlist

Regards,
Lalitha

But how could I get the list of other "directories" or "folders" like Desktop, "My Computer", etc. You know with the tree like that

Desktop
\_ My Computer
\_ A:
\_ C:
\_ D:
\_ MyFolderOnDeskop
...
...

If you want to get the list of folders you can make use of the same Filesystem object as below:

Sample code
==================

Dim filesys, demofolder, subfol, folcoll, folist
Set filesys = CreateObject("Scripting.FileSystemObject")
Set demofolder = filesys.GetFolder(<DriveName got earlier&gt
Set folcoll = demofolder.SubFolders
For Each subfol in folcoll
folist = folist & subfol.Name
Next

MsgBox follist


You can't get for desktop and mycomputer. I donno how to do that.

Regards,
Lalitha

Desktop is a folder under C:\Windows. The rest like Recycle, My Computer and Network Neighborhood aren't real folders but system functions with special handling required by the system.

There is however a shBrowseForFOlder API that will produce a treeview like list of this stuff. Here is sample code.
Start a new project. Paste this code into the general declarations section of the form. Run it.

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
Const BIF_RETURNONLYFSDIRS = 1
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
private Sub Form_Load()
'KPD-Team 1998
'URL: http://www.allapi.net/
'[email protected]
Dim iNull as Integer, lpIDList as Long, lResult as Long
Dim sPath as string, udtBI as BrowseInfo

With udtBI
'set the owner window
.hWndOwner = me.hWnd
'lstrcat appends the two strings and returns the memory address
.lpszTitle = lstrcat("C:\", "")
'Return only if the user selected a directory
.ulFlags = BIF_RETURNONLYFSDIRS
End With

'Show the 'Browse for folder' dialog
lpIDList = SHBrowseForFolder(udtBI)
If lpIDList then
sPath = string$(MAX_PATH, 0)
'get the path from the IDList
SHGetPathFromIDList lpIDList, sPath
'free the block of memory
CoTaskMemFree lpIDList
iNull = InStr(sPath, vbNullChar)
If iNull then
sPath = Left$(sPath, iNull - 1)
End If
End If

MsgBox sPath
End Sub

That is great, I could try to do something with it, but is there n.e. documentation on the shell32.dll?? In fact I would like to create my own drive combobox with images...
If u know somewhere I could find some example. thx

Shell32.dll is a real big animal and is the kernel for Windows Explorer functions. To many to mention in one place. Microsoft.com probably is the ultimate source for documentation but many VB Web sites have bits and pieces of the functions available in Shell32
