SH Dialog Box - Set default directory?

[Skute]

Hi,

does anyone know howto set the default opening directory for the directory browsing dialog? (SHDialog)

It always opens up in the root directory at the moment which is quite inconvenient!

Thanks

Never heard of SHDialog, but in SHBrowseForFolder you pass a BROWSEINFO structure as in parameter.
Specify a callback function that acts on BFFM_INITIALIZED and selects the desired folder.

See Q179378 in MSDN.

with the SHBrowseForDialog, is it necessary to use the IMalloc structure?

I have been using SHBrowseForDialog for ages without using IMalloc, but after reading that article i tried it but it just caused an exception (invalid memory address on free).

The code im using is here:

void ChooseDirectory(HWND hwnd, char* Directory)
{
//LPITEMIDLIST pidlRoot = NULL;
LPITEMIDLIST pidlSelected = NULL;
BROWSEINFO bi = {0};
LPMALLOC pMalloc;

char strFoldername[MAX_PATH] = &quot;&quot;;
char strDirectory[MAX_PATH] = &quot;&quot;;
char* pRelative = NULL;

if (SUCCEEDED(SHGetMalloc(&pMalloc)))
{
ZeroMemory(&bi,sizeof(bi));
bi.hwndOwner = hwnd;
bi.pidlRoot = 0;
bi.pszDisplayName = strFoldername;
bi.lpszTitle = &quot;Choose a directory&quot;;
bi.ulFlags = BIF_RETURNONLYFSDIRS;
bi.lpfn = NULL;
bi.lParam = 0;

pidlSelected = SHBrowseForFolder(&bi);

if (pidlSelected)
{
SHGetPathFromIDList(pidlSelected, strFoldername);

if (strlen(strFoldername) > 0)
{
GetCurrentDirectory(MAX_PATH, strDirectory);
_strlwr(strDirectory);
_strlwr(strFoldername);
pRelative = strstr(strFoldername, strDirectory);
if (pRelative == NULL)
strcpy(Directory, strFoldername);
else
{
pRelative = pRelative + strlen(strDirectory);
strcpy(Directory, &quot;.&quot;
strcpy(Directory + 1, pRelative);
}
}

pMalloc->Free(pMalloc);
}

pMalloc->Release();
}
}


Can you spot anything wrong? Is it necessary to have the pMalloc structure?

(oh btw, thanks for the link, the callback function worked great!)
