Hello,
I am to do something as simple as browse the network neighborhood and return the path selected... After a bunch of research the only thing I found that really fits my needs is an article by Paul DiLascia.

http://msdn.microsoft.com/msdnmag/issues/05/06/CAtWork/

Anyway, I am trying to modify his code to only display the network neighborhood and nothing else... He provides 2 functions for filtering out items. I have been playing around with this for hours and I can't seem to figure it out. Can anyone help me out? I only want to display the network neighborhood.

// Used for custom filtering. You must override to specify filter flags.
HRESULT CFolderDialog::OnGetEnumFlags(
	IShellFolder* psf,		// this folder's IShellFolder
	LPCITEMIDLIST pidlFolder,	// folder's PIDL
	DWORD *pgrfFlags)		// [out] return flags you want to allow
{
	BFTRACE(_T("CFolderDialog::OnGetEnumFlags(%p): %s\n"),
		psf, GetPathName(pidlFolder));

	return S_OK;
}


// Used for custom filtering. You must override to filter items.
HRESULT CFolderDialog::OnShouldShow(
	IShellFolder* psf,		// This folder's IShellFolder
	LPCITEMIDLIST pidlFolder,	// PIDL for folder containing item
	LPCITEMIDLIST pidlItem)		// PIDL for item
{
	BFTRACE(_T("CFolderDialog::OnShouldShow(%p): %s: %s\n"), psf,
		GetDisplayNameOf(psf, pidlFolder, SHGDN_NORMAL),
		GetDisplayNameOf(psf, pidlItem, SHGDN_NORMAL));

	return S_OK;
}

Thanks, I have looked at that before but I would prefer to use this other method.

Actually I have to override these functions.. Here is the following but I am still unsure on how to filter...

//////////////////
// Get flags for custom filtering: Only enumerate folders. This is only
// called when custom filtering is used.
//
HRESULT CMyFolderDialog::OnGetEnumFlags(IShellFolder* psf, LPCITEMIDLIST pidlFolder,
	DWORD *pgrfFlags)
{
	BFTRACE(_T("CMyFolderDialog::OnGetEnumFlags\n"));
	
	*pgrfFlags = SHCONTF_FOLDERS; // show only folders
	
	return S_OK;
}

//////////////////
// Determine whether to display item: doesn't actually do anything, just
// illustrates the function in action through TRACE diagnostics.
//
HRESULT CMyFolderDialog::OnShouldShow(IShellFolder* psf,
	LPCITEMIDLIST pidlFolder,
	LPCITEMIDLIST pidlItem)
{
	BFTRACE(_T("CMyFolderDialog::OnShouldShow(%p): %s: %s"),
		psf, GetPathName(pidlFolder), GetDisplayNameOf(psf, pidlItem, SHGDN_NORMAL));

	SFGAOF attrs;
	psf->GetAttributesOf(1, &pidlItem, &attrs);
	BOOL bShow = attrs & (SFGAO_FILESYSTEM | SFGAO_HASSUBFOLDER);
	
	BFTRACE(_T(" [attrs: %08x]: %s\n"), attrs, bShow ? _T("Yes") : _T("No"));
	

	return bShow ? S_OK : S_FALSE;
}

Use SHGetSpecialFolderLocation() with the CSIDL_NETWORK flag to get the PIDL of the Network root folder, then pass this PIDL to SHBrowseForFolder() as the pidlRoot member of the BROWSEINFO structure. This will force the "Browse For Folder" tree to be rooted at the root network folder.

You can use SendMessage to send a user defined message from the child dialog to the parent dialog.

Help !

I'm looking for the reverse API of LoadBitmap.
where can i find a function, or an implementation
who takes a CBitmap object and pushing/adding
it back to the resource....
resource of some other(not running)program.

i want to create RT_BITMAP resources dynamically.

what's the difference between data() and c_str() of basic_string?

The followings are there declaration:
const value_type *data( ) const;
const value_type *c_str( ) const;

but I thank they have the same use.

The later is guaranteed to end with '\0'. The former is not.

I have tested them.

string str( "Hello world" );
char szTemp1[12], szTemp2[12];
strcpy(szTemp1, str.data());
strcpy(szTemp2, str.c_str());

when I view the memory, szTemp1 and szTemp2 have the same content,
and both of them end with '\0'.

// szTemp1: 48 65 6c 6c 6f 20 77 6f 72 6c 64 00
// szTemp2: 48 65 6c 6c 6f 20 77 6f 72 6c 64 00

Note the word "guaranteed". The C++ Standard requires c_str to return a pointer to an array that ends with `\0`, and it does not require (nor forbid, for that matter) for data.

The implementation you tested obviously returns a pointer to the same piece of memory in both cases, but it is not necessarily the case for all implementations.

Also, have you tested the case when you have an empty string? c_str() would be guaranteed to return the pointer to `\0`. For data(), again it is implementation dependent, but I would be surprised if it returned the same thing.

I have tested the case for an empty string too. Though the result is same with the nonempty case, I have believed what you said is right. Thank you again Smile | :)
