I agree! There are great techniques and deep philosophy within the book. But the style: *jump here and jump there so often* ... kind of flaw of this book.
Sometimes in a paragraph, for example it says: "foobar (Section 16.3.5) ...". And I moved there onto section 16.3.5, and I found nothing related.
Sometimes in the index it says that some jargon lies on page N, and I moved to that page N. I searched over and over within that page but couldn't find that word.

i don't know, i read a french traduction, perhaps these foo weren't traduced, or they were traduced into sometithing else.
for the links, i agree, but when i read it first, i didn't take time of going further in the book to see what he was talking about ; i said to me, "well, i'll see later..." 
anyway, we do agree it is a good book

I started studying C++ with the book "C++ From The Ground Up, 2nd Edition" by Herbert Schildt. I read that book thoroughly from the beginning to the end without any skim.
But later I read Bjarne's book in the way picking topics which I haven't learned. So index plays an important key to me.
I read the English version, although I am a native Chinese speaker. I hate computer books in Chinese so much, because the translation for some jargons is bitch, hard to understand.

A French translation.
traduce[^], (English):
to strongly criticize someone, especially in a way that harms their reputation.
traduction[^] (French):
translation.
When I was in university, I studied the French language. But never have a chance to use in practice. Now I've forgot all about French... 
Je ne sais pas...

Hi chaps,
Just been getting into a bit of ADO database programming and have been able to connect to a database on the same computer that my program is running on. All the resources I have read seem not to mention how to access a SQL db on a network or on a server, say the other side of the world.
The connection part of the program (in the document class) goes along these lines:
m_pConnection->Open(_bstr_t(L"Provider=Microsoft.Jet.OLEDB.3.51;Data Source=C:\\Program Files\\Microsoft Visual Studio\\VCDb.mdb;"),
_bstr_t(L""),
_bstr_t(L""),
adModeUnknown);
In this example I am connecting to a Microsoft Access DB. But supposing I want to connect to a MySQL DB running on a Linux Machine, or just simply another SQL DB on a Microsoft server ?
Apologies for the stupidity, but I am kind of new to this are of programming and am getting frustrated with poor recourses I have found.
Any help will greatly appreciated

I'm trying to draw a bitmap with a highlighted effect with the following code:
HBRUSH hSelBrush = CreateSolidBrush(GetSysColor(COLOR_HIGHLIGHT));
DrawState(hDC, hSelBrush, NULL, MAKELPARAM(hBmp, 0), 0, x, y, ImgWidth, ImgHeight, DST_BITMAP | DSS_UNION);
DeleteObject(hSelBrush);
The problem is that it doesn't do it on the white pixels. Is there any way to fix it?
-thanks

Hi!
I would like to change the cursor of the entire system temporarily, so I cannot use SetSystemCursor. My goal is to hide the cursor, so I can either hide it or change it to a blank one that I load. ShowCursor(FALSE) seems to only apply to the current window.
Any help would be appreciated.

That's because the cursor is a shared resource. In Win32 one app isn't allowed to control such a resource since it would affect all apps running on the system.

You can change system wide cursor using ::SetSystemCursor() API. Then what else the problem u have. Just create a blank cursor in ur resource editor( here IDC_CURSOR1) Load it... Create another one cursor which is having ur system cursor ( here IDC_CURSOR2).
void CTestDlg::OnHideCursor()
{
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR1 ) ;// User your blank cursor here
HCURSOR h2 = CopyCursor ( h1 ) ;
::SetSystemCursor ( h2, OCR_NORMAL ) ;
}
void CTestDlg::OnShowCursor()
{
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR2 ) ;// User your system cursor here
HCURSOR h2 = CopyCursor ( h1 ) ;
::SetSystemCursor ( h2, OCR_NORMAL ) ;
}
Thatzaal..;)

Thanks
The hide cursor code works great, but when I show the cursor again, I want it to be the user's cursor, not one stored in my resources. So instead of AfxGetApp()->LoadCursor(...) for the show function, I'm trying this:
HCURSOR h1=LoadCursor(0,IDC_ARROW);<br />
HCURSOR h2=CopyCursor(h1); <br />
::SetSystemCursor(h2,OCR_NORMAL);
Which doesn't work, and I have to restore the cursor otherwise. How can I restore the original cursor?

Ya.. I dOno why its not working... but there is another one solution to restore the system cursor (without using ur resource). Declare a HCURSOR m_h; member variable to ur dlg class.
void CTestDlg::OnHideCursor()
{
m_h=CopyCursor(LoadCursor(NULL,IDC_ARROW)); // Store system cursor in m_h
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR1 ) ; // Load ur cursor
::SetSystemCursor ( h1, OCR_NORMAL ) ; // Change system cursor with urs
}
void CTestDlg::OnShowCursor()
{
::SetSystemCursor ( m_h, OCR_NORMAL ) ; // Restore system cursor from m_h
}
It is working well for me. Try urself.
Hava nice day;)
with regards

That works wonderfully! Thank you very much! I tried doing something similar but mine involved copy cursor and it didn't work right, so simple and elegent.

I am writing a web download installer and need to make it as small as possible. A lot of MFC is a black box to me so I am not sure which pieces I can hack out and still expect the program to behave as expected.
It is currently 210 KB and I only wrote a thousand or so lines of source code (including comments). There is only 1 window and it is a dialog-based app. It does use the file open common dialog box and afxinet.h
Thanks!

lets see... you could use an executable compressor like UPX for instance. Once you compile it run upx and compress your executable. get it here

sorry about the link... get it at www.upx.sourceforge.net

Shrinking the size of an MFC app in VC++ 7.x is difficult. In VC++ 6.0, you could get it down to about 160k but not much more than that.
Since it's dialog based, I'd consider just converting it to a standard windows app and taking the parts of afxinet.h that you need.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

If you want to keep it small then I think you should avoid using MFC.... write a simple application without them...
Did you compiled your app using the static MFC library version? You cannot hope that who will use your installed has already the MFC Dlls

I've looked all over this site, and googled it but I can't seem to get the count function to work. here's what I have:
int iCount = count(vecWords.begin(),vecWords.end(),sWord)
where sWord is a struct variable of the type the vector is holding. I even try to hard-code a 1 or any other type of variable in there and I keep getting the same error message:
error C2678: binary '==' : no operator found which takes a left-hand operand of type 'std::allocator<_Ty>::value_type' (or there is no acceptable conversion)
Can anyone help? Thanks!!
If it's broken, I probably did it

Have you defined the == operator for the type used as your vector element?
|
|
|
|

NO, I haven't. thanks!! but can I define an '==' for a struct?

Sure:
struct foo
{
int x;
bool operator== ( const foo& rhs ) const
{
return x == rhs.x;
}
};
