If you are using MFC and your listbox is derived from CListCtl:

m_MyList.EnsureVisible( m_MyList.GetItemCount()-1, FALSE );

If using WIN32 inlude windowsx.h and use the following macros:

#include <windowsx.h>
...

ListBox_SetCurSel(hwndCtl, ListBox_GetCount(hwndCtl))

If you mean:

How do I remove duplicated values from a vector, you should look at the algorithm (IIRC) std::unique_copy().

If all you want is a container for unique values, you might want to consider using std::set<> instead of vector.

By unique_copying the vector to another vector?

Determining the type of a member variable

Hi guys,

Does anybody have an idea how I can get the type of
a class member variable ?

I'm looking for something like:

template<class c=""> swap(C &v)
{
typeof(v.x) t; //<-- t has to be the same type as v.x
t = v.x;
v.x = v.y;
v.y = t;
}

Thanks in advance.

You could use dynamic_cast and if the returned pointer is not NULL, it was a good cast. Smile | :)

Given that in this case all you want to do is swap the member, why not call swap on that? The nice part about this is that it requires at compile time that what you pass into swap_x_with_y has an x and y member variable. The realswap function will happily just swap over whatever you give it, providing they are the same type.

template<class T> swap_x_with_y(T &v)
{
  realswap(v.x, v.y);
}

template<class T> realswap(T &x, T&y)
{
 T t = x;
 x = y;
 y = t;
}

hello,im interested to know if there is a way to capture the output from a program like telnet or something and save it to a text file?
i see no reason why this isnt possible,so if any 1 has any info regarding this,id like to know...

thanks 4 ya time

You may use pipes.

at the prompt type

dir *.* > directory.txt

you may also send the output to 2 devices.

Make a file with all the commands you want to carry out in telnet seperated by a newline.
Don't forget to include q a the end.

then save the file as telnet.cmd or something you will remember.

at the command prompt enter

telnet < telnet.cmd > telnet.res

That will work just fine.

The other way is to echo to a file but that is noit good practice any more because window may not support the src device anymore.

Well, I looked around, and everyone seems to think this is hard to do, but here's what I came up with:

BOOL CD3PlayRecsDlg::OnInitDialog()
{
	CDialog::OnInitDialog();

	CRect frameRect;
	GetDlgItem(IDC_STATIC_VIEWFRAME)->GetWindowRect(&frameRect);
	m_pView = new CDialogView(NULL);
	ScreenToClient(&frameRect);

	DWORD winStyle = WS_CHILD | WS_HSCROLL |  WS_VSCROLL |  WS_VISIBLE | WS_BORDER;
	m_pView->Create(NULL, NULL, winStyle, frameRect, this, AFX_IDW_PANE_FIRST+1, NULL);
	m_pView->SetScrollSizes(MM_TEXT, CSize(100,100));
	m_pView->MoveWindow(&frameRect, TRUE);

	return TRUE;  // return TRUE  unless you set the focus to a control
}

In the dialog tempate, I created a static frame to use as an anchor (where and how large I wanted the view window to be), and then created a CScrollView object and moved it into position. The tricky bit was getting it not to crash when the dialog box tried to display itself, but calling SetScrollSizes fixed that.

Am I missing something? Should this be hard to do than it appears to be?

Hi Jason

Try some ASSERTS
like

CHttpMyDlg* pDlg = ( CHttpMyDlg*) pParam;
ASSERT(pDlg);
ASSERT(pDlg->IsKindOf(RUNTIME_CLASS( CHttpMyDlg)));

Then take pDlg-> and set your rect and view.
When you get the error you may see your mistake. I looks good to me so I am just trying to give you another way to look at it.

I don't understand what you're trying to do/say.

This is a dialog-based app, and the code I posted is in the OnInitDialog() function of the main dialog.

It works, and even under debug, there are no memory leaks or anything...

Why would I care what kind of dialog it is?
