i got a file.txt:
Test1 < - 1rst line
Test2
How i put a string:
CString TString = "How I write text in files";
in the file (but each line hold 10 chars so the file.txt would be):
Test1 <-1rst line
Test2
How I writ (10 chars)
e text in (10 chars)
files

CString sFilePath="your path/filename go here";
CStdioFile file;
CString sOutput="How I writ (10 chars)\r\ne text in (10 chars)\r\nfiles";
try {
if (file.Open(sFilePath,CFile::modeReadWrite|CFile::modeNoTruncate)) {
file.SeekToEnd(); // Go to end of file.
file.WriteString(sOutput); // Append text
file.Close();
}
}
catch (CException * e) {
e->ReportError(); // Popup description of exception
e->Delete(); // Clean up.
}
catch (...) { // Catch any other exceptions
AfxMessageBox("Failed to open file!");
}

Thx i am going to try this.
But the CString sOutput it would have random char lenght
(so i have to GetLength(); )
int m_Count = sOutput.GetLenght();
int m_Edit = m_Count / 10 // = How many lines i need
if ( m_Edit%10 != 0)
{
m_Edit = m_Edit +1;
}
Now to edit the the sOutput in the form i want :
for ( m_Edit >= 1 ;m_Edit-- )
sOutput.SetAt(m_Edit*10)="\\n";
SetAt is the right command to add the \n in the string?

Your making it harder than it should be. (NOTE: the appending to existing file thing was an assumption so if your wanting to create the file new each time if it doesn't exist and overwrite the previous file if any, use the modified open flags below)
CString sFilePath="c:\\temp\\myfile.txt";
CStdioFile file;
CString sOutput="This is a long string to see how to append every 10 chars in the string to a file";
int nCount=sOutput.GetLength();
try {
if (file.Open(sFilePath,CFile::modeReadWrite|CFile::modeCreate)) {
file.SeekToEnd(); // Go to end of file.
for (int i=0;i<nCount;i+=10) {
file.WriteString(sOutput.Mid(i,10)+"\r\n"); // Append text
}
file.Close();
}
}
catch (CException * e) {
e->ReportError(); // Popup description of exception
e->Delete(); // Clean up.
}
catch (...) { // Catch any other exceptions
AfxMessageBox("Failed to open file!");
}

Also, a word of caution concerning the \n.
newlines can be \n or \r\n in text files but when outputting your results to an edit control, you will need the \r\n pair. Not that it matters but in case you start dumping your text output to a GUI I thought I'd give you a heads up since your just using a newline in your snippets.
For what it's worth...

Hi,
I'm new in Visual C++ .net 2005 and I'm writing a Newsreader and i have the following problem:
on my form load event i'm reading a text file into my listview, the textfile contains about 66000 lines, so when the form loads it doesn't respond for a few seconds. I have already searched the new for an answer to my question but nothing could help me out...it also tried to use the virutal mode for the listview but I don't get on with this mode 
I'm becoming desperate...so it would be very nice if someone could help me on this, maybe sending me a tutorial or a very simple sample code
thx in advance
No need to invent new thing when they already exist

I think I know why it's taking so long to load the listview.;P
|
|
|
|
|
I also know that the 66000 lines are taking much time but there must be a way to load them faster
|
|
|
|
|
make 11 threads which load 6000 lines ? (isnt that be 11 times faster )
|
|
|

thanks for your answer, but i have already found this link on the net but it couldn't help me out because this code is not in vc++ .net 2005

I need to have a control like CDragListBox (I need dragging), but it should also have a check box and a small bitmap for each item. Is it posible (and quite easy) to add check box and bitmap to CDragListBox control?
Or should I rather use CListCtrl? What's easier to implement?
Can you give me some advice please? And by the way some samples if you have any.

I am not a code writer, except in HTML, and I don't plan on learning the super long code for a print out, or in this case a window.
So I have a program that will save files, open and make new ones (for a thing you wouldnt understand)but I dont know how to make a new window. I Have actualy read and skipped around and I know that in there the code is "Make_A_WINDOW()" but wouldn't know where to put it...
Also, I have a menu but I dont know how to link them together.
~I'm using the Microsoft Visual Studio .NET 2003 program and all (hopefuly)in visual mode.
Hmm, how do I make this stupid thing WORK!

You close your eyes, breathe deeply (very important), and say (three times) "another window without any stupid code"
If that doesn't work, you may want to look up CWnd::Create in MSDN. I'm guessing that's not what you wanted but since this is a Visual C++/MFC discussion board, I'd have to say that CWnd::Create is the way to go around here to get create another window. I've never heard of "Make_A_WINDOW" but they don't let me out much.
.NET might have a "system.output.gui.windows.telepathy.commands.new.window.without.any.stinking.code" namespace so I would give that discussion board a try.

Nice , I believe in 10 year time, might be it will part of Namespace

Hmmm...
I wonder if I could just do 2 diffrent progrects and then some how compile them together.
Or I could just learn the code...

What's wrong with this code? It draws, but with great flickering. I red many articles about double buffering, but it seems that I don't understand them.
Please help. :/
void CGrafikView::OnDraw(CDC* pDC)
{
CGrafikDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO:
CRect rc;
GetClientRect(&rc);
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
CBitmap bmpMem;
bmpMem.DeleteObject();
bmpMem.CreateCompatibleBitmap( pDC, rc.right, rc.bottom );
CBitmap * oldBmp = dcMem.SelectObject( &bmpMem );
CPen penBorder( PS_SOLID, 1, crBordercolor );
CPen penNull;
penNull.CreateStockObject( NULL_PEN );
CBrush brushBg( crBgcolor );
CBrush brushFill( RGB(204,204,204) );
CBrush brushNull;
brushNull.CreateStockObject( NULL_BRUSH );
CPen * oldPen = dcMem.SelectObject( &penNull );
CBrush * oldBrush = dcMem.SelectObject( &brushBg );
dcMem.Rectangle(&rc);
dcMem.SelectObject( &penBorder );
dcMem.SelectObject( &brushFill );
dcMem.Rectangle( startX-1, startY-1, startX+uWidth+1, startY+uHeight+1 );
//--------------------------------------
pDC->BitBlt( 0, 0, rc.right, rc.bottom,
&dcMem, 0, 0, SRCCOPY ); //--------------------------------------
dcMem.SelectObject( &oldPen );
dcMem.SelectObject( &oldBrush );
dcMem.SelectObject( &oldBmp );
}

Screen is flickering. I know that double buffering should eliminate it, but I don't know how to do this?

Make sure you change the OnEraseBackground to NOT paint the background. This should be handled in your Draw code.
BOOL CYourView::OnEraseBkgnd(CDC* pDC)
{
// TODO: Add your message handler code here and/or call default
return FALSE; // Prevent "flicker" in double buffer environments
return CScrollView::OnEraseBkgnd(pDC);
}

Thanks
And one thing more. I create many pens and brushes in OnDraw(). Are they created and destroyed each time OnDraw is called, or are they static objects automaticly?
void CMyView::OnDraw(CDC* pDC)
{
CRect rc;
GetClientRect(&rc);
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
CBitmap bmpMem;
bmpMem.CreateCompatibleBitmap( pDC, rc.right, rc.bottom );
CBitmap * oldBmp = dcMem.SelectObject( &bmpMem );
CPen penBorder( PS_SOLID, 1, crBordercolor );
CPen penNull;
penNull.CreateStockObject( NULL_PEN );
CBrush brushBg( crBgcolor );
CBrush brushFill( RGB(204,204,204) );
CBrush brushNull;
brushNull.CreateStockObject( NULL_BRUSH );
//....
