I download the emule source code from the sourceforge but it is difficult to config for the reliant library. Where can I download the emule source code with the reliant library?

HI,
Is there a standard/Portable equivalent functions for MSVC++ functions like : strncpy_s(), strcpy_s(), _stricmp(), strcat_s(), sprintf_s(), fopen_s() etc.
I am porting a VC6 application to VC8, and getting tones of warnings regarding non-secure functions. I want to replace the non-secure functions with secure ones. But, till now i have not been able to find a portable solutions. I want a portable solution as some part of my app. connects with unix while others with windows.
Thanks in advance.

you could easily create those functions yourself from scratch (for the simpler ones), or create a safety wrapper around existing unsafe ones (for the more complex ones, mainly the I/O functions).

What functions you use in your code and what systems your code talks to are mutually exclusive. In other words, you can use whatever code you want and be able to talk to Windows, Unix, Mac, OS400, etc.

Had great fun at a virtual robot coding night, using http://robocode.sourceforge.net/ where you develop a robot in Java or .NET to fight against others robots. I am now looking for a C++ version, is there a Robocode or similar game, ideally with similar API to reuse your robot strategies?
Thanks for tips!

C++? bah. try CoreWars[^] - it uses an Assembly-like language! and it's the original! (i wrote a version for my C64, back in '85)
or, if you must, there's C++Robots[^] and CRobots[^]

Hello folks!
Am looking for a way to do this: i have a rectangle that specifies the available space for some text. I want to display as much as possible of this text. What i mean is, if the text fits nicely in the rectangle, it should be displayed as usual, centered with wordbreaks as needed (DrawText with DT_WORDBREAK | DT_CENTER). However, when the specified rectangle is too small, the text doesn't fit into it even with wordbreaks (e.g. there are a few long words) then i'd like the text to e.g wrap around at positions where the long words would "hang out" of the rectangle.
First i tried DT_CALCRECT with DrawText to check if the text fits, if yes then i simply draw it with DrawText and go on, if not, then i tokenized the string using space as separator/delimiter. Then i iterated trough the words and checked the widths of the words and if they were too wide then i'd find the character inside the word which would hang out of the rectange and inserted a space. After this, i used DrawText again with DT_WORDBREAK to display the string. This works reasonably well but not well enough because it produces things like this:
(the text is "This is somewhat longer" and there's space for 3 lines)
---------
|This is|
|somewha|
| t | <- a whole word is lost ("longer")
---------I guess one alternative i can go for is wrapping the whole string
---------
|This is|
|somewha|
|t longe| <- i see more of "longer" here
--------- but am not sure if doing this is the only/best way, and also i don't know how to wrap text aside of writing it character by character myself checking before each letter if it would hang out or not and "linefeeding" as needed + handling spaces specially (something like not display them if they are at a linebreak position). I have a faint memory from the good old times that something like DT_WORDWRAP or somesuch existed but i see no trace of it now so it's either gone or it never had existed at all and i have a few bit errors in my memory.
Any suggestions before i go into implementing the char-by-char thing? There should be a better way (i don't wish to go into dynamically selecting font sizes, let us assume the font is fixed)...
P.S: Am using GDI (CDC::DrawText and friends...)

Don't know who downvoted you, but have my 5 in compensation. It's an interesting question (even if the answer is going to be WAAAAY too long). I suspect you're going to be forced into "measure each char and draw it somewhere" stuff.

Thank you very much. I don't know what the problem is with my question that it needed a downvote.
Anyways, for now i went with the following aproach: if the text doesn't fit, i go char by char, calculate sizes, when i hit the "line-end" then i insert a linefeed ('\n') in the string and after i hit the end of the string, i output it with DrawText without DT_WORDBREAK.

Isn't this why we have scrollbars?

No, this is why we have larger monitors.

Thanks for the suggestion but not in this situation. Basicly what i have is (something similar to) a "grid" of rectangular cells, each cell displaying textual information for the user, the user can resize this "grid", and i would like to present him as much information as i can when he "shrinks" the whole thing. Displaying a scrollbar wouldn'd be really usefull here i guess. The user will have tooltips to aid him but the more he can determine by just looking at the thing the better it should be.

Hi,
Just started using the boost libraries to do asynch i/o and not sure if this is the best forum for this but will post anyway.
First question I am specifying a delimiter character in the call but when I display what I get back it looks like it is also implicitly returning when a LF \'n' char is reached even though this isn't my delimiter. Could this method have default delimiters that need to be managed? I haven't seen this in the documentation so far.
Secondly, the second argument in the call is a "boost::asio::streambuf b". What's the best way to extract the message from the buffer and put it into an std::string?
I've played around with:
size_t n = b.size();
b.commit(n);
std::istream is(&b);
std::string s;
is >> s;
But now sure what's going on under the covers here.
Any help would be appreciated.
Thanks

Hi,
I have owner draw button control and setfont to 20. But I am getting font height using GetTextMetrics() but I am not getting 20 anywhere, I am getting 16 each time.
HDC dc= ::GetDC(this->m_hWnd);
TEXTMETRIC tm;
::GetTextMetrics(dc,&tm);
|

It would be more useful if you posted the code where you select the font.
Just say 'NO' to evaluated arguments for diadic functions! Ash
|
|
|
|
|
m_font.CreateFont(20,0,0,0,FW_BOLD,0,0,0,0,0,0,0,0,_T("Arial"));
SetFont(&m_font);
|
|
|
|
|
Does this code actually change the font of the button control?

The value above does not equate to a 20 point font, you must first convert it to device units as described here[^].
