Call IXMLDOMNode::cloneNode() on the node you get from the source document.

Something like:

IXMLDOMElementPtr pNode = get_element_from_source();

IXMLDOMNode *pClonedNode;
pNode->cloneNode(VARIANT_TRUE, &pClonedNode)

Now insert pClonedNode into your target document.

CControlBars always on top of CMDIChildWnd

I have some control bars (CDialogBar actually, but the problem is the same for all CControlBar derived classes) owned by my CMDIChildWnd derived class. These control bars contains document specific data.

The problem I can't seem to find a solution to is when one of these control bars is in a floating state and I have more than one document open. The floating control bar is alway on top of all CMDIChildWnd derived windows, making it difficult to know to which it actually belongs.

(This can be easily tested by just adding the toolbar from the CMainFrame to the CChildFrame class and opening a few document windows and let a toolbar float.)

The behaviour I'd like to see is that the control bar should be on top of its owning CMDIChildWnd, but below any other CMDIChildWnd that might be in front of it.

Does anyone have a clue how to do this?

I have tried SetWindowPos(&my_child_frame,...) in various places without any luck.
Maybe I could set the window style of the CMiniFrameWnd somehow?

Any ideas would be appreciated.

I run MFC (obviously) and VS2003, though I doubt that matters.

If you really want to use InstallShield, why didn't you look at the company website[^] ?
On the other hand, if you would like to use a free tool, I suggest InnoSetup[^]

Hi,
Can you please help me and told me how can i set option of my RichEditCtrl to display the All line which exceeds the width of RichEditCtrl and not with scroll.
ie when i have a text string like that "blablablablablablablablablablablablablablablablablablabla"
and the width of the RichEditCtrl is less than the length of this string it should display the part of this string and display the rest in newline.

Did you even bother to read my reply when you posted this yesterday?

The text will wrap automatically when you use the ES_MULTILINE style.

DDX and Arrays

stevepqr11-Jun-09 22:32

VS6.0, C++

I have a control I need to 'interact' with, I set it up the usual way with
ID = IDC_TINY1 and using ClassWizard to assign a variable CStatic m_Tiny1, as expected this gives me:-

DDX_Control(pDX, IDC_TINY1, m_Tiny1);

and in the header:-

CStatic m_Tiny1;

Now though I have 11 more identical controls and instead of having m_Tiny1, m_Tiny2, m_Tiny3 etc I think it would be better to have an array m_Tiny[12] but there seems to be no way to assign each element of the array using ClassWizard. So I decided to edit these entries manually to give me:-

DDX_Control(pDX, IDC_TINY1, m_Tiny[0]);
DDX_Control(pDX, IDC_TINY2, m_Tiny[1]);
DDX_Control(pDX, IDC_TINY3, m_Tiny[2]);
.
.
.
DDX_Control(pDX, IDC_TINY12, m_Tiny[11]);

and:-

CStatic m_Tiny[12];

This appeared to work just fine until I came to edit another control using ClassWizard I then got the error:-

Parsing Error: Expected ")" Input Line:"DDX_Control(pDX,IDC_TINY1,m_Tiny[0]"

I'm assuming this is VS telling me I have an entry in the DDX that it didn't put there even though it quite happily will compile and run it.

So to the problem: Is having array elements in DDX entries a valid thing to do? If yes then how do I do it without the error?

Thanks

You forgot ");" at the end of the line. That's exactly what VS is telling you also Smile | :)

cedric, i dont think he has forgotten to add the closing bracket because in the query where he is adding the control variable i can see the bracket being put properly.

Thanks for that but I forgot it from the post not the code! message actually reads:-

Sorry!

put the above code after like this //}}AFX_DATA_MAP

//}}AFX_DATA_MAP


<blockquote class="FQ"><div class="FQA">stevepqr wrote:</div>DDX_Control(pDX, IDC_TINY1, m_Tiny[0]);
DDX_Control(pDX, IDC_TINY2, m_Tiny[1]);
DDX_Control(pDX, IDC_TINY3, m_Tiny[2]);
.
.
.
DDX_Control(pDX, IDC_TINY12, m_Tiny[11]);</blockquote>

in DoDataExchange Function. It should work.

Thanks but the code is already included inside the '//}}AFX_DATA_MAP' I didn't change this part just added lines inside the markers.

i had the same problem and this was solved by adding the code outside the markers.

ClassWizard only parses the lines inside its comments.

You should place your custom lines outside the class wizard's special comments. Just below the comment line //}}AFX_DATA_MAP, for example.

CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CYourDialogClassName)
  // lines added by ClassWizard
  // DDX_Control(...);
  // DDX_Text(...);
//}}AFX_DATA_MAP
// lines added manually
DDX_Control(pDX, IDC_TINY1, m_Tiny[0]);
DDX_Control(pDX, IDC_TINY2, m_Tiny[1]);

You should also take definitions into account in header file.

// Dialog Data
//{{AFX_DATA(CDlgFoo)
enum { IDD = IDD_DIALOG1 };
CStatic m_static1;
//}}AFX_DATA
CStatic m_Tiny[12];

The lines added manually in that way, won't be parsed by ClassWizard.

I thought of this already - when I try it I get 'Cannot Add New Member' when I try to add a new member but otherwise it works ok. I'm getting round this by commenting out the above lines adding new members and then uncommenting them, PITA!! Smile | :)

The problem may be with <your project="" name="">.clw file. Close project then rename that file. ClassWizard will re-create it. Or you may edit yourself if you know what you do. Smile | :)

Thanks! Deleting the .clw and regenerating it did the trick - strangely, after recreating it I had to exit VS and restart but now all is good.

Thanks to everyone else too for their suggestions.

Saving and Restoring Toolbars (Win32 SDK)

I am trying to Saving and Restoring Toolbars status by sending TB_SAVERESTORE message. MSDN says if you don't have user data to store with the toolbar buttons, you don't need to handle TBN_SAVE or TBN_RESTORE notification. So, now, the saving and restoring are fine, the program restores toolbar buttons correctly. However, if I try to kill that toolbar control restored, Visual Studio gives a warning message "Unhandled exception at 0x7c901230 in win32tst.exe: User breakpoint." This warning only shows if the program is launched inside the Visual Studio. It just runs fine if launched outside of Visual Studio. So I tried to debug with WinDbg.exe, and it gives a more detailed description of that user breakpoint warning "Invalid Address specified to RtlFreeHeap". Anybody knows what's wrong with the restoring? Thanks.

case WM_NOTIFY:
{
switch (((LPNMHDR)lParam)->code)
{
case TBN_GETBUTTONINFO:
{
LPTBNOTIFY lpTbNotify = (LPTBNOTIFY)lParam;

// Pass the next button from our array. There is no need to
// filter out buttons that are already used; they will be
// ignored.
int buttonCount = sizeof(tbButtons) / sizeof(TBBUTTON);
if (lpTbNotify->iItem < buttonCount)
{
lpTbNotify->tbButton = tbButtons[lpTbNotify->iItem];
return TRUE;
}
else
{
// No more buttons.
return FALSE;
}
}
break;

case TBN_QUERYINSERT:
case TBN_QUERYDELETE:
return TRUE;
case TBN_ENDADJUST:
{
TBSAVEPARAMS tbSave;
tbSave.hkr = HKEY_CURRENT_USER;
tbSave.pszSubKey = "Software\\key";
tbSave.pszValueName = "tbsave";
SendMessage(GetDlgItem(hWnd,ID_TOOLBAR),TB_SAVERESTORE, TRUE, (LPARAM)&tbSave);
}
return TRUE;
}
}

We have a huge C++ code, developed on Microsoft Visual Studio 6.0. This contains but server and client code. Now the requirement is to add a support for memory leak detection.
So can any one help me to code, which should check the existing whole code base for memory leaks.

Thanks,
