Can anyone help me to get answers to my these two questions :
1. How can I copy a file bit -by- bit? And also store that bit temporarily in any variable.
2. How to write a single bit in file? Is this method write.
fstream dfile;
char bit = '1';
dfile<<bit-48;
what does="" the="" above="" code="" writes="" to="" dfile="" a="" byte="" or="" bit.???
codes="" compiled="" in="" borland="" c++="" 3.0="" will="" be="" nice="" for="" me="" cos="" i'm="" using="" that="" as="" my="" compiler

The smallest I/O resolution you have is one byte so you'll have to work with 8 bits at a time.
You can use bitwise and shift operators to manipulate bits in a byte.

Recently I begin to program with GDI+,and I want to contruct a Bitmap object with the function Bitmap( Class type, String resource ),because my bitmap is in resource(is it right to use the function?).But I don't know how to set the parameters "type" and "resource"~ Help~

Construct CBitmap object to first load the bitmap from resource.
Then use that object to get the handle of bitmap.
Finally ,from that handle you can construct a GDI+ Bitmap object by using
Bitmap::FromHandle() function.

Or you can use this constructor:
Bitmap(HINSTANCE, const WCHAR *)
e.g.
Gdiplus::Bitmap bitmap(hInst, MAKEINTRESOURCEW(IDB_BITMAP));

Hello,
I want to display tooltips in Wnd when the mouse is in some rect. So i use ON_NOTIFY(TTN_NEEDTEXTW, 0, OnToolTipNotify) and ON_NOTIFY(TTN_NEEDTEXTA, 0, OnToolTipNotify) Like,
void CLadderWnd::OnToolTipNotify(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
TOOLTIPTEXTA* pTTTA = (TOOLTIPTEXTA*)pNMHDR;<br />
TOOLTIPTEXTW* pTTTW = (TOOLTIPTEXTW*)pNMHDR;<br />
...<br />
CString str = "abcd\n1234";<br />
pTTTA->lpszText = (LPSTR)(LPCTSTR)str;<br />
}
I hope display text with multiline, but it will output just one line and display "abcd1234". I have tried "\r\n" or "\r" and they are the same.
How can I do it!
Thanks!

I would like to check for the existance of a file before I create it, since I dont want to recreate the file if it exists. The help in visual studio 2005 mentions EXIST operator but does not give a clue as to the syntax for using it. Can someone please enlighten me with the code to make this work?
Thanks alot,
Terry

Can you use _access()?

Do you just want to append to it?

That worked perfectly, thank you very much.

Or you can use of FindFirstFile and check return value of this function.

Thanks for your input,
I tried to use this without susccess. It seems very complicated to me.
I created the HANDLE object.
HANDLE hFile;
I then created a pointer to the string containing the path.
const char fPath = "C:\\Myfile";
I created the handle as follows;
hFile = FindFirstFile(hFile, NULL);
This built fine but always return INVALID_HANDLE_VALUE even though the file was there.
I am sure I dont have this right. Notice I did not try to use the second perameter, which might also be a problem. Sure seems like alot of code just to see if a file's there or not.

Try to this code and see result
HANDLE hFile;
WIN32_FIND_DATA win32;
hFile = FindFirstFile("c:\\1234.txt", &win32);

Thanks,
That is alot easier than what I was trying to do with it. Thanks for your help.

You're welcome.
I think best thing for me is when I can solve a problem for people.

I belive the suggestion David had was easier than this but, here is another way that seems pretty simple .
GetFileAttributes();
If it fails it returns a DWORD 0xFFFFFFFF.
