VK_RETURN actually invokes a default button in your dialog, which happens to be your OK button.
You could unchek "default button" property for it in the resource editor, or at a run time.

I have a block of data, say name, address, etc (could be 1000's of chars long) that wish to encrypt using a key and then decrypt using the same key. WHERE can I get some source. I checked out Codeproject, doesn't seem to have what I need.
Any help?
TIA

Hi !! I'm programming under Linux and compiling with GCC (C and C++ code). Where can I find manuals for all the functions and libraries that I can use ??
I've tried to use the gotoxy(int, int) function but there's not "conio.h" and if I include it, it begins to send error messages.
I need a manual (if its downloadable much better) where I can find all the functions and libraries.
Thanks in advance !!

Your Linux install should have all the documentation you could need. Look into the optional parts of the distribution.
In the area of what I assume 'gotoxy' (which is not any sort of standard C/C++) might mean try 'man curses'.

It was only an example, that function sets the cursor to the column and file wherever you want to go. But I would like to know how can I call the documentation about programming... I tried "man gcc" and it told me lots of things but there's anything about all the allowed functions and so on.
I'm programming under downloaded Linux Mandrake 10.0.
Thanks in advance !!

There is no guarantee that notepad.exe exists in any particular directory.

the program is to display NotePad ICON on the left up corner in window.
void CSampleView:
OnDraw(CDC * pDC)
{UINT stFileInfo;
if( :: SHGetFileInfo(_T("c:\\windows\\notepad.exe"),0,
&stFileInfo,sizeof(stFileInfo),SHGFI_ICON))
{
pDC ->DrawIcon(10,10,stFileInfo.hIcon)
}
}
BUT COMPILE ERROR:

Change

hi:chopchop,thx your kindness
but when i changed ,the following error:

You should do a bit more work and look it up in MSDN...

Anyway, the member is not DisplayName, rather it is szDisplayName

if(::SHGetFileInfo(_T("c:\\windows\\notepad.exe"),0,&stFileInfo,sizeof(stFileInfo),SHGFI_ICON))

ALL OK,THX

hi i added a list view control made it report style and mapped a variable list view variable to it in mfc
now when i go to add a column it wont cooperate
i tried m_List.InsertColumn(0, "Hello");
and sometimes itll do nothing other times itll do a sliver of a column with nothing in it
what is the proper way to set up columns?
thanks
|

The column has probably been added, but its width is too small. Change the call to this to verify:
m_List.InsertColumn(0, "Hello", LVCFMT_LEFT, 100);

Hi,
I'd like to browse a large text file (more than 100 Mbytes) to extract some information.
With standard File access method, my hard drive is overloaded by access request so that my treatment is very long.
What is the correct method to do that?
Thanks,
Regards

What do you mean? fgets() ?
One way would be to use fread() with a "decent" buffer size of say, 32768 bytes. However, you would have to parse this buffer in order to read the data "line by line" i.e. detecting CRLF's.

If you are doing a one pass search, just read in chunks in, say, 32k increments [larger won't buy you anything].
If you are doing a multi-pass search, use memory mapped files.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Tanks for all the reply
I actually use std::getline with the default buffer size.
Could you please explain why reading in chunk will provide better result than mapped files for single pass threatments ?
By memory mapped files, you mean overlapped I/Os ?
Thanks,
VF
