Can't you just count them while they are generated ? or maybe there is a counter somewhere that sets the number of lines generated that you could use ?

You could use string::getline[^] in a loop to read the file line by line till the end of the file. In this loop you can have a counter which counts the number of lines in the file.

You should #include Windows.h which will include Winreg.h for you. You may need to link with Advapi32.lib.

If, and that's a big IF, I understand correctly ...

Have a look at the topic of "file association"; google for that and you should be able to
find a lot of information on how to associate a file type/name/extension, in your case a docx file
to a particular application.

The easiest way, non-programatically, is to right-click on the docx file and choose "Open With" and
select the "Choose default program" (that's on vista, I don't have XP) and select your application.

The width of each character in a font is different, unless it is a monospaced font.
You can use GetTextMetrics[^] to get the average width of the characters of a font.

Hi,
if i debug my application, and want to close them, i receive sometimes this strange error in

// Disconnect connection
void CDatabase::Close()
{
	ASSERT_VALID(this);

	// Close any open recordsets
	AfxLockGlobals(CRIT_ODBC);
	TRY
	{
		while (!m_listRecordsets.IsEmpty())
		{
			CRecordset* pSet = (CRecordset*)m_listRecordsets.GetHead();
			pSet->Close();  // will implicitly remove from list
			pSet->m_pDatabase = NULL;
		}
	}
	CATCH_ALL(e)
	{
		AfxUnlockGlobals(CRIT_ODBC);
		THROW_LAST();
	}
	END_CATCH_ALL
	AfxUnlockGlobals(CRIT_ODBC);

	if (m_hdbc != SQL_NULL_HDBC)
	{
		RETCODE nRetCode;
		AFX_SQL_SYNC(::SQLDisconnect(m_hdbc)); // here is error???
		AFX_SQL_SYNC(::SQLFreeConnect(m_hdbc));
		m_hdbc = SQL_NULL_HDBC;

		_AFX_DB_STATE* pDbState = _afxDbState;

		AfxLockGlobals(CRIT_ODBC);

Look at the call stack and you can figure out the sequence of functions that are being called.
From this you can understand how the control reached that particular function.

Window TopMost window on top???

Arrin28-Jul-09 3:39

28-Jul-09 3:39

Hello community,
how to create a second window that is always on top of a main window,
so if i click on the main window that this pop up window stay on top until my function is finished??!?
I create a simple dialog with the resource editor and set "Set Foreground" to true,
but even if i click on the main dialog this new little dialog is in the background, how to avoid this?
If i set "Topmost" to true, than is my pop up dialog always on top, but for all other windows too,
and i like that hi is only for my main dialog in the foreground!?

Thanks for help
Arrin

EDIT: after i show my child dialog and bring him to top i disable my main dialog to make him unklickable and when my funktion is finished i enable him again,
but im not sure that this is the right way!?

// in my funktion:
dlgProgress.ShowWindow(SW_SHOW);
dlgProgress.SetForegroundWindow();
EnableWindow(FALSE); // for main dialog
// after funktion:
EnableWindow(TRUE); // for main dialog

Looks like you need a modal dialog.
If you're using MFC, call CDialog::DoModal[^].
Otherwise call DialogBox[^].

I may have had a similar problem back several months ago. I have a modeless PropertySheet (a modeless tabbed dialog window) separate from my main Doc-View window.

I created my modeless PropertySheet window:

<br />
// Modeless property sheet - with parent window as such and call to SetWindowPos() allows for property sheet to be on top<br />
m_pSettings->Create(this, WS_SYSMENU | WS_MINIMIZEBOX | WS_POPUP | WS_CAPTION | DS_MODALFRAME | DS_CONTEXTHELP, WS_EX_DLGMODALFRAME);<br />
m_pSettings->SetWindowPos(this,0,0,0,0,SWP_NOMOVE | SWP_NOSIZE);<br />

I do recall that there was something special to this (modeless property sheet) and the peeps here helped me out!

Hi,

i am using MFC application in this application i need to display the received messages from the server (may be a chance for receiving more than one messages at a time) i need to display the received and send messages in the Listbox.
i tried it in normal way, but the UI getting freezed after some time. I can able to log that message. So i tried it in some other way, like using queue
the received messages are added in the queue and at thet time timer is running and one thread will pop the pushed messages in to the ListBox.

Using thread how can i get the pushed value?

Thanks,
Ratheesh.

You should add the messages to the queue using a worker thread, then notify it to the GUI thread (using, for instance PostMessage). The GUI thread eventually pops messages from the queue and displays them. of course you've to lock in same way queue access.

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