MSXML and tinyXML are two options for you.

I use Expat to read XML files. See http://www.libexpat.org/.

I use to this to read Excel XLSX files once they are unzipped with the zlib library.

We build our own library on top of MSXML (painful).

Now, I'm trying to push http://pugixml.org/[^] for our XML need; I've used it for relatively small and not too complex XML files and it works great.

I'd rather be phishing!

Hi All,
i need C/C++ developers that have skills about reverse engineering. I need to reading custom closed file format, parse the content and fill a defined structure.

if you have experience with reverse engineering and you want more detail about this task please contact me @ luca_2000it@yahoo.it or reply to this message with your private contact.

Thanks

Dialog controls not showing up on a child dialog

Kiran Satish6-Aug-15 7:54

I am rewriting an old application in VS2010 that was developed in vc++6.0. I am trying to keep the basic structure of the GUI the same which consists of a main Dialog in which I have multiple child dialogs. All the child dialogs except one are simple with no border, title bar or system menu. This works fine in VC++6.0, but on VS2010, none of the controls that I have in those child dialogs show up when I run the program.

Am I missing something simple here that I am not aware of?

thanks

Yes, some more detail. Is this MFC or basic Win32? How are the dialogs created, how are they displayed? etc.

Its a MFC dialog based application. Main dialog is created when the application is created using "New Project" wizard and the child dialog is created by inserting a "Insert Dialog" in resource view and then adding dialog controls to it.

Did you remember to include your dialog template resources in the build? The code will (probably) compile happily without them, but fail to initialize the dialog controls.

Tooltip behind dialog

_Flaviu5-Aug-15 0:31

Which could be the reason why a tooltip is layered behind the dialog ?
Here is the implementation:

C++

class CNotifyDlg : public CAlertDialog
{
	CToolTipCtrl m_ToolTip;
}

and

C++

BOOL CNotifyDlg::PreTranslateMessage(MSG* pMsg) 
{
	// TODO: Add your specialized code here and/or call the base class

	switch(pMsg->message)
	{
		case WM_LBUTTONDOWN:		
		case WM_LBUTTONUP:		
		case WM_MOUSEMOVE:
			m_ToolTip.RelayEvent(pMsg);
	}

	return CAlertDialog::PreTranslateMessage(pMsg);
}
BOOL CNotifyDlg::OnInitDialog()
{
	CAlertDialog::OnInitDialog();

	m_ToolTip.Create(this);
	m_ToolTip.AddTool(GetDlgItem(IDCANCEL), _T("My message"));
	m_ToolTip.Activate(TRUE);

	return TRUE;
}

LRESULT CNotifyDlg::OnButtonMouseOver(WPARAM wParam, LPARAM lParam)
{
	if(m_btnClose.GetDlgCtrlID() == (int)wParam)
		m_ToolTip.UpdateTipText(_T("My message again"), GetDlgItem(IDCANCEL));
	m_ToolTip.Update();

	return 0;
}

and I see the tooltip window, but is just behind the dialog ... I can not figure out why is happen this ...

CAlertDialog is derived from CDialog ... what I have done wrong here ? Could you help me ?
Thank you.

Has your dialog the top most status (e.g. by calling SetWindowPos with HWND_TOPMOST or setting the WS_EX_TOPMOST style)?

Then change that.

Re: Tooltip behind dialog

_Flaviu5-Aug-15 1:52

The only call with SetWindowPos is

C++

SetWindowPos(
    FindWindow(_T("Shell_TrayWnd"), _T("")),
    m_nStartPosX,
    m_nStartPosY,
    rc.Width(),
    rc.Height(),
    SWP_NOOWNERZORDER | SWP_NOACTIVATE);

inside of CAlertDialog ... I don't think this call is the issue ...

But you gave an idea:

C++

m_ToolTip.Create(this, TTS_ALWAYSTIP | TTS_NOPREFIX);
m_ToolTip.AddTool(GetDlgItem(IDCANCEL), _T("Bla bla bla"));
m_ToolTip.Activate(TRUE);
m_ToolTip.SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOSIZE);

I don't know if it's all right, but seem to work ... Smile | :)

Thank you !!!

I was just going to suggest removing SWP_NOOWNERZORDER.
However, fine to hear that it seems to be solved.

Yep, I removed SWP_NOOWNERZORDER flag, and everything seem to be all right now, without m_ToolTip.SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOSIZE); ... so, it is better solution ! Thank you again ! Smile | :)

Hi Johen. After all, I can not give up SWP_NOOWNERZORDER flag ... It should be there, but I want to ask you what is the best solution to put tooltip above CDialog which has SWP_NOOWNERZORDER flag:

C++

SetWindowPos(
   FindWindow(_T("Shell_TrayWnd"), _T("")),
   m_nStartPosX,
   m_nStartPosY,
   rc.Width(),
   rc.Height(),
   SWP_NOOWNERZORDER | SWP_NOACTIVATE);

the solution was the following:

C++

BOOL CNotifyDlg::OnInitDialog()
{
   CAlertDialog::OnInitDialog();

   m_ToolTip.Create(this, TTS_ALWAYSTIP | TTS_NOPREFIX);
   m_ToolTip.AddTool(GetDlgItem(IDCANCEL), _T("Close this notification"));
   m_ToolTip.Activate(TRUE);
   m_ToolTip.SetWindowPos(&CWnd::wndTopMost, 0, 0, 0, 0, SWP_NOOWNERZORDER | SWP_NOSIZE);

   return TRUE;
}

It is ok ? To be frank, I don't like idea to setup tooltip as top level window ... there is another solution ?

Flaviu.

A tooltip should be a top level window to ensure that it is visible. It is only shown when requested by the user and closed when clicking anywhere with the mouse. So it does not interfere with other GUI elements. If you have a working solution I would stay with that.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
