SHGetIDListFromPath and SHBrowseForFolder

[jj2007]

To supply SHBrowseForFolder with a proper start folder, I searched for SHGetIDListFromPath and found no official version but an undocumented reference to ordinal #162 in Shell32.dll

The good news is it works under Win7
The bad news is it's pretty useless, you see the dialog and the folder, but you cannot go anywhere else, it's the only folder available :(

Any ideas? Special flags etc? I attach a test program, curious to see which Windows versions support it. Might produce an exception - who knows what happens inside Shell32 ;)

include \masm32\MasmBasic\MasmBasic.inc   ; download (version 24 August needed)
.data?
bInfo   BROWSEINFO <>
buffer   db MAX_PATH dup(?)

  Init

  Dll "Shell32"      ; #162 found in some VB forums
  Declare #162=SHGetIDListFromPathW, 1
  mov bInfo.pidlRoot, SHGetIDListFromPathW(wChr$("C:\Masm32\Examples"))

  mov edi, offset buffer
  mov bInfo.pszDisplayName, edi
  mov bInfo.lpszTitle, Chr$("Select a folder")
  invoke SHBrowseForFolder, addr bInfo
  .if eax
   invoke SHGetPathFromIDList, eax, edi
  .else
   mov edi, Chr$("Nothing selected")
  .endif
  Inkey "Selected folder: [", edi, "]"
  Exit
end start

Assuming this is what you actually want to do, have some code ;)

Code Select Expand

    .IF (eax == BFFM_INITIALIZED)
        invoke SendMessage, hwnd,BFFM_SETSELECTION,TRUE,lpData
    .ENDIF


Really cute trick, Tedd :t

In the meantime, I opted for GetOpenFileName, simply because it allows to set wildcards (\Masm32\*.asm), too. Thanks a lot for BFFM_SETSELECTION, it will serve in another occasion ;-)

Still, I'd like to see an occasion where the pidlRoot method yields useful results :icon_cool:
