Adding to CFolderDialogImpl

Oh! That is totally dependent on the object that is being embedded.
Those are custom properties I guess.

In the wizard I'm working on I need to bring up a window that allows our users to select a folder to gather files from. I figured that CFolderDialogImpl would work just dandy. However, I wanted to remove the 'Make New Folder' button (which I was able to do by using Spy++ to find out it's ID and hide it) and replace it with a check box that the user can check to specify whether or not to recurse into subdirectories of the selected folder. I created a dialog in the resource editor with just a checkbox in it (IDC_CHECK_RECURSE is the resource ID for the checkbox, and it belongs to IDD_ENHANCED_FOLDER_DIALOG).

My problem is that I can't, for the life of me, get the check box that I created in the resource editor to show up! I know that I haven't set anything up to handle the messages for my check box. I'm more concerned with just getting the dang thing to show up first.

Here is what the class looks like...

class CFolderDialogEx : public CFolderDialogImpl<CFolderDialogEx>
{
protected:
	typedef CFolderDialogImpl<CFolderDialogEx>	baseClass;
	typedef CFolderDialogEx					thisClass;
public:
	// Enumerations
	enum DialogIds
	{
		// NOTE: Dialog IDs found using SPY++
		_IDC_STATUSTEXT = 0x00003741,
		_IDC_TITLE      = 0x00003742,
		_IDC_NEW_FOLDER = 0x00003746,
	};

	enum { IDD = IDD_ENHANCED_FOLDER_DIALOG };

	// Constructor
	CFolderDialogEx(HWND hWndParent = NULL, LPCTSTR lpstrTitle = NULL, UINT uFlags = BIF_NEWDIALOGSTYLE | BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT)
		: baseClass(hWndParent, lpstrTitle, uFlags)
	{

	}

	BEGIN_MSG_MAP(thisClass)
		//NOTIFY_HANDLER(IDC_CHECK_RECURSE, BN_CLICKED, OnRecurseChecked)
	END_MSG_MAP()

	// Overrides from base class
	void OnInitialized()
	{
////////////////////////////////////////////////////////////////////////////////////////////////////////////////
//			*****************	Copied from FolderDialogStatusText.h	**********************

		// NOTE: We compensate for the issue where BIF_STATUSTEXT
		//  isn't honored if BIF_NEWDIALOGSTYLE is present.
		//  Some would say its a bug, some would say its by design...
		if((m_bi.ulFlags & BIF_NEWDIALOGSTYLE) == BIF_NEWDIALOGSTYLE &&
			(m_bi.ulFlags & BIF_STATUSTEXT) == BIF_STATUSTEXT)
		{
			int fontHeight = 11;  // 8 point Tahoma at 96 DPI

			CWindow title = ::GetDlgItem(m_hWnd, _IDC_TITLE);
			RECT rcTitle = {0};
			if(title)
			{
				CFontHandle titleFont = title.GetFont();
				CLogFont logFont;
				titleFont.GetLogFont(logFont);
				if(logFont.lfHeight < 0)
					fontHeight = -1*logFont.lfHeight;

				title.GetWindowRect(&rcTitle);
				::MapWindowPoints(NULL, title.GetParent(), (LPPOINT)&rcTitle, 2);
				rcTitle.top -= 1;
				rcTitle.bottom -= fontHeight + 1;
				title.SetWindowPos(NULL, &rcTitle, (SWP_NOACTIVATE | SWP_NOZORDER | SWP_SHOWWINDOW));
			}

			CWindow status = ::GetDlgItem(m_hWnd, _IDC_STATUSTEXT);
			if(status)
			{
				status.EnableWindow(TRUE);
				status.ModifyStyle(0,SS_PATHELLIPSIS|SS_NOPREFIX);

				rcTitle.top = rcTitle.bottom + 2;
				rcTitle.bottom = rcTitle.top + fontHeight + (fontHeight/2);

				status.SetWindowPos(NULL, &rcTitle, (SWP_NOACTIVATE | SWP_NOZORDER | SWP_SHOWWINDOW));
			}

			// NOTE: We'd really like to have the status window resize appropriately
			//  when the dialog resizes, but currently that doesn't happen.
		}

////////////////////////////////////////////////////////////////////////////////////////////////////////////////

		CRect		rect;
		CWindow		makeNewFolderButton = ::GetDlgItem(m_hWnd, _IDC_NEW_FOLDER);

		if ( makeNewFolderButton.IsWindow() )
		{
			makeNewFolderButton.ScreenToClient( &rect );
			makeNewFolderButton.ShowWindow( SW_HIDE );


			CWindow		recurseBox = ::GetDlgItem( this->m_hWnd, IDC_CHECK_RECURSE );
			DWORD		error;

			error = GetLastError();

			if ( recurseBox.IsWindow() )
			{
				recurseBox.MoveWindow( &rect );
				recurseBox.ShowWindow( SW_NORMAL );
			}
		}
	}

....

recurseBox.m_hWnd is NULL, which makes the if ( recurseBox.IsWindow() ) fail.
error is ERROR_CONTROL_ID_NOT_FOUND

I'm completely aware that I may be going about this all wrong. All I want to do is have a folder dialog with the checkbox that let's the user specify whether or not to recurse into subdirectories. I don't really care how it gets done, as long as it gets done. Any help would be very much appreciated!

Thanks!

I'd be tempted to do it slightly differently for various reasons, the main one being that I don't think SHBrowseForFolder (the underlying API) allows controls to be added to its dialog.

Anyway - why not have a separate dialog with three controls - an edit box containing the text of the path, a 'browse' button that would show the folder browsing dialog (the result of which would get put back into the text box) and a check box for the recursion control.

the question that relate to CreateInstance

The following code is correct:
FRLE_FALSE(m_pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
CString sRssDBFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\DB\\RssTab.mrr"));
try{
m_pRssManager->Open((LPCTSTR)sRssDBFile);
}
catch(...)
{
MessageBox(::AfxGetMainWnd()->m_hWnd, _T("database file is already damaged,will create a new empty database file"),_T("message"),MB_OK|MB_ICONINFORMATION);
CString sRssDBTemplateFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\NewRssTab.mrr"));
if( ::PathFileExists(sRssDBTemplateFile) ){
::CopyFile(sRssDBTemplateFile, sRssDBFile, FALSE);
RssLib::IRssManagerPtr pRssManager;
FRLE_FALSE(pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
pRssManager->Open((LPCTSTR)sRssDBFile);
m_pRssManager = pRssManager;
}
}

the following code is not correct:
FRLE_FALSE(m_pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
CString sRssDBFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\DB\\RssTab.mrr"));
try{
m_pRssManager->Open((LPCTSTR)sRssDBFile);
}
catch(...)
{
MessageBox(::AfxGetMainWnd()->m_hWnd, _T("database file is already damaged,will create a new empty database file"),_T("message"),MB_OK|MB_ICONINFORMATION);
CString sRssDBTemplateFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\NewRssTab.mrr"));
if( ::PathFileExists(sRssDBTemplateFile) ){
::CopyFile(sRssDBTemplateFile, sRssDBFile, FALSE);
m_pRssManager ->Open((LPCTSTR)sRssDBFile);
}
}

May I ask the reason ? Why have to recreate the RssManager object ?

thanks a lot!

Try formatting the code using the 'code block' button, so that indents aren't lost - that is pretty much unreadable, which makes it unlikely that someone's going to answer your query.

Dynamic UUID?

lucyh3h12-Mar-09 7:37

12-Mar-09 7:37

Hi,

I wonder for an ATL COM DLL, is there any way I can dynamically assign the UUIDs to the COM class and interface, i.e. without recompiling the code? Assume all the registries are setup correctly. Is it possible that when the dll gets loaded, the CLSID, IID are reset to the new value?

Thanks!
Lucy

Re: Dynamic UUID?

«_Superman_»12-Mar-09 19:56

Equivalent for CPtrList in ATL

12-Mar-09 19:56

This actually must be in the COM forum. Anyway...

You can use UuidCreate API to generate new UUIDs.
Replace the registry entries with the new UUIDs under CLSID and IID keys under HKEY_CLASSES_ROOT.
Do this after the COM DLL has been loaded.
This should work.

Class Object Pointers, we need to store it an List to track the objects created, We are now using vectors for this purpose

Jonathan Davies10-Mar-09 4:22

If as you say you need to store in a List it's probably best to see Stuart's answer, though vector will or course do the job.

CPtrList is not in c++, it is in vc++

Create using the parent and position as parameters, making sure they are set to visible. Messages from controls are WM_COMMAND with the controls ID as a parameter.

non dialog object sink advise causing assert to be thrown during advise initialisation

10-Mar-09 1:13

Sorry I don't have any code that I can find, I just seem to remember doing this sort of thing. I had a quick look on the net... and found an MS MFC example [^] which should translate to ATL. What have you tried?

Hi all,

I have an ATL control based on CComCompositeControl. In the control's dialog box I have a web browser, from which I am sinking events. I also have another COM object which is not on the dialog box from which I'm sinking events. I'm getting an assert thrown as my control initialises in AtlAdviseSinkMap. In this ATL method there is a loop which goes over all the ids of the sink entries and calls:

HWND h = pT->GetDlgItem(pEntries->nControlID);
ATLASSERT(h != NULL);

While this works perfectly for the embedded web browser, the other object not on the dialog box causes an exception.
Is there a setting I can use to inform the initialisation that it is not a dialog object and that this is not appropriate but without the assert being thrown.

Many thanks

Cheers
Tom
