You probably have to create a managed C++ project to do that.

Calling SHBrowseForFolder from unmanaged VC++ code?

Does anyone know how to call SHBrowseForFolder (msdn link) from normal VC++ code? I've found an article describing how to call it using a MFC class but I don't want to go and learn how to use MFC classes I'd love to just call this function directly.

I'm not at a computer where I can test this but I'm just wondering if anyone else has wanted to open a browse for folder dialog from unmanaged c++ code. Or should I just bite the bullet and use

(i forget where i got this - Google search, most likely)

// The initial folder, and the result of the function are contained in buf

bool BrowseForFolder(HWND hWnd, char *buf)
{
	// Global pointer to the shell's IMalloc interface.
	
	LPMALLOC g_pMalloc;
	
	// Get the shell's allocator.
	
	if (!SUCCEEDED(::SHGetMalloc(&g_pMalloc)))
		return false;
	
	BROWSEINFO     bi;
	LPITEMIDLIST  pidlMyComputer;  // PIDL for MyComputer folder
	
	LPITEMIDLIST  pidlBrowse;      // PIDL selected by user
	
	
	// Get the PIDL for the Programs folder.
	
	if (!SUCCEEDED(::SHGetSpecialFolderLocation(hWnd, CSIDL_DRIVES, &pidlMyComputer)))
		return false;
	
	// Fill in the BROWSEINFO structure.
	
	bi.hwndOwner = hWnd;
	bi.pidlRoot = pidlMyComputer;
	bi.pszDisplayName = buf;
	bi.lpszTitle = "Select root folder";
        // 0x40 = new style dialog (includes "Make New Folder" button)
	bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_RETURNFSANCESTORS | 0x40; 
	bi.lpfn = BrowseCallbackProc;
	bi.lParam = (LPARAM)buf;
	
	// Browse for a folder and return its PIDL.
	
	pidlBrowse = ::SHBrowseForFolder(&bi);
	bool result = (pidlBrowse != 0);
	if (result) 
	{
		if (!::SHGetPathFromIDList(pidlBrowse, buf))
			result = false;
		
		// Free the PIDL returned by SHBrowseForFolder.
		
		g_pMalloc->Free(pidlBrowse);
	}
	
	// Clean up.
	
	g_pMalloc->Free(pidlMyComputer);
	
	return result;

The MSDN link gives an example of how to use it without MFC (that is, there is no MFC code in their example). You will have to use COM and some Win32 API calls, but that should have been expected.

copying HTML from a CWebBrowser in XP sp2 [modified]

Maximilien20-Sep-06 4:04

I'm trying to implement a copy ( to clipboard ) from a IWebBrowser2; this is what I'm doing, and it works on Win2K, but not on XP, especially SP2.

We generate HTML on the fly and "give" it to the browser, it's not based on a HTML file.

HRESULT hr;
// select the entire document
hr = _Browser->ExecWB(OLECMDID_SELECTALL, OLECMDEXECOPT_DODEFAULT, NULL, NULL);

// copy the text to Clipboard
hr = _Browser->ExecWB( OLECMDID_COPY, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);

// clear the selection
hr = _Browser->ExecWB( OLECMDID_CLEARSELECTION, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL);

After Further reading ...

There is a new "Local Machine Zone Lockdown" setting that seems to restrict some operations, like the one above.

one suggestion from Microsoft that might be working for us ( I will try it ) is to add the "Mark of the Web" on the HTML, something like :

<!-- saved from url=(0014)about:internet -->
<!-- saved from url=(0020)http://www.phdcc.com -->

but I'm not sure this will work from HTML not from a "real" web page ...

Anyone with a clue ?

Thanks.

I found several things that "don't work" when you use the COM interface to write HTML to the control. In those instances I stopped using that technique and went to a temporary file solution.

I understand, I felt the same way, but after I implemented it I felt much better about it. Big Grin | :-D

Seriously, there are API's for working with temporary files so it is not that big a deal, really. I found performance negligible. I imagine the parsing of the HTML and loading of the DHTML DOM is a much bigger operation than file IO, and that must be performed either way.

Posting the same message twice...to multiple code-related bulletin boards (as you have done) without first at least Googling is pretty rude. Do try to avoid it in future, it only infuriates the very people you're asking for help.

Search for CRegKey class. It is one of the easiest classes to use.

// using Mid
CString str = _T("abcde");
CString s = str.Mid(2, 3);

// using Right
s = str.Right(3);

you certainly not searched the web that much...

MSDN give you this : CString::Mid()[^]

CString s1 = "abcde";
CString s2 = s1.Mid(2, 3);

You get your answer with CString::Mid but maybe its helpful for you

<br />
extract right part from String<br />
	CString str_T("abcdef");<br />
	CString s;<br />
	s=str.Right(3);//def<br />

<br />
extract left part from String<br />
	CString str_T("abcdef");<br />
	CString s;<br />
	s=str.Left(3);//abc<br />

<br />
And CString::Mid extract middle part from string
