Yes, from that almost i am gona crazy. The result is O.K. (for all numbers in file). Help me please with 100, 200, ... elements in array !!!

just use the same array, once you hit a number where (current_number % 100 == 0) then do your biggest/smallest check and reset current_number to 0, keep going on after that and it will just reuse your 100 item array.

I done so:

while (fscanf(in,"%f",&element) != EOF)
{
table[num_elements] = element;
current_number=element;
current_number%100==0;
num_elements++;
}

but steel dont work propertly.

How about:

while (...)
{
    table[num_elements] = element;
    num_elements++;
    if ((num_elements % 100) == 0)
    {
        biggest(...);
        smallest(...);
        num_elements = 0;
    }
}

I try, but compiler return erors:

too few arguments to function `float * biggest(float *, int)'
at this point in file
too few arguments to function `float * smallest(float *, int)'
at this point in file

How to switch from vertical to gorizontal split windows?

I want to switch dynamically from vertical to gorizontal split windows.
It's very easy (IMHO). But have little problem.
When my program started, I have two vertical split windows:

<br />
<br />
//In this function I have pointer to CCreateContext structure <br />
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,<br />
	CCreateContext* pContext)<br />
{<br />
	CreateSplitters(m_nRows, m_nCols, m_actRow, m_actCol, pContext);<br />
	return TRUE;<br />
}<br />
<br />
BOOL CMainFrame::CreateSplitters(int nRows, int nCols, int m_actRow, int m_actCol, CCreateContext* pContext)<br />
{<br />
	m_bInitSplitter = FALSE;<br />
	my_RightView = RUNTIME_CLASS( CRightHTMLView );<br />
	my_LeftView = RUNTIME_CLASS( CMyTree );<br />
<br />
<br />
<br />
	//here is standart procedure of creating<br />
	//--------Create 2 splitter views-------------<br />
	CRect cr; <br />
	GetClientRect( &cr);<br />
	//if ( !m_wndSplitter.CreateStatic( this, 1, 2 ) ) <br />
	if ( !m_wndSplitter.CreateStatic( this, nRows, nCols ) ) <br />
	{ <br />
	    MessageBox( "Error setting up splitter frames!", <br />
			"Init Error!", MB_OK | MB_ICONERROR ); <br />
		return FALSE; <br />
	}<br />
	int width = cr.Width();<br />
<br />
	<br />
	if ( !m_wndSplitter.CreateView( 0, 0, my_LeftView, <br />
		CSize(width/5, cr.Height()), pContext ) || <br />
		!m_wndSplitter.CreateView( /*0, 1,*/m_actRow, m_actCol, my_RightView, <br />
			CSize(4*width/5, cr.Height()), pContext )) <br />
	{ <br />
	    MessageBox( "Error setting up splitter frames!", <br />
					"Init Error!", MB_OK | MB_ICONERROR );<br />
		return FALSE; <br />
	}<br />
	m_bInitSplitter = TRUE;<br />
<br />
	return TRUE;<br />
<br />
}<br />
<br />

In in other functions I do not have pointer to CCreateContext structure, that is needed to create splitters.
Have can I retrive this pointer in any place of my object? This is very easy but I couldn't do it.

Detection of code pages

Hi all.

Has anyone any ideas on how to detect (programatically) the code page of a text file in Win32? At least in a way that makes the correct guess 90 % of the time?

For now, I'm testing different code pages with MultiByteToWideChar (CP_ANSI - CP_UTF8), counting the number of letters in the string (using iswalpha), and then the code page with the most letters wins. Feels shaky. This problem must have been around for ever, but I can't find any good ideas on how to deal with it.

Btw, there's a function called IsTextUnicode in the NLS API, does anyone know how to use it on reversed (MacOS) Unicode-files? I've tried the XXX_REVERSED flags, but the stupid function returns zero for every kind of input.

Any help or clues would be appreciated.

Connecting database

Recently I gone through a project in which I used a ".mdb" database.But whenever I took the application in different systems,I had to connect,once, the certain database manually by clicking "ODBC data sources Administrator" in control panel and choosing the right path.
I think it is not suitable for the users ,actually when the application is distributed,to do the right steps in connecting the database.
So,is it possible to code it within the project so that it automatically connects to its required database at the time of initialisation of the application for the first time?

how display full text in a list control

I have a list control in Icon view. I add somes items with icon into my list, and my list open, I don't see all the text for each items. What I see is the icon, and under the icon, the begin of the text with "...". How can I see the full text without I need to click on the icon ?

Maybe this will help you:

LVS_EX_LABELTIP
Version 5.80. If a partially hidden label in any list-view mode lacks ToolTip text, the list-view control will unfold the label. If this style is not set, the list-view control will unfold partly hidden labels only for the large icon mode.

As far as i know, the list will never display more than two lines of text. However, you can increase the amount of text displayed by allowing more space between icons (this will let each row of text become longer). Use CListCtrl::SetIconSpacing() or LVM_SETICONSPACING to accomplish this.

BTW - rocky's suggestion is also good, as it lets you see the text while hovering the mouse over an icon, while keeping the spacing reasonable.

HRESULT hr;
BSTR bstrValue ;

node=document1->createNode(NODE_ELEMENT,"xml","version");
pIXMLDOMProcessingInstruction=document1->createProcessingInstruction ((BSTR)"xml",(BSTR)"version");

hr=document1->raw_createProcessingInstruction ((BSTR)"xml",(BSTR)"version",&pIXMLDOMProcessingInstruction);

the errors occured are:
in creating the node is :

SNTP server

I've to develop an simple SNTP server (no time performance are required).
Can someone give me some advices to develop it ?

I've created a RAW socket in order to receive any
message sent to my pc, to separate NTP messages
and to know the sender IP address and port. But it doesn't work !!
Is this the right way ?
Can someone help me ? Thanks a lot !!

I tried doing some stuff in windows with RAW sockets a while back and none of it would work (outside of simple PING stuff). I came to find out that windows didn't fully support RAW sockets. I don't know if this is still true with XP, but you may want to check into that.

Don't use RAW sockets, (S)NTP uses normal UDP. Create an UDP socket that listens on port 123.
