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.

|

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[^].

The code you showed (CSMTP::get_response) isn't in the stack you gave!

Please, don't repost your question. This is considered rude.
Besides, you have been given advice to use your debugger, did you already tried that ? If you are in a hurry, why don't you try to solve the problem instead of waiting that people give you the complete solution.
We've been giving you everything that you need to fix your problem. It seems you are not really willing to learn as your username would suggest it...

|

ok sir
actully i m not find out the exact problem by call stack window.
i dont know how to use it.
so...
|
|

When the crash occurs, you can see the call stack window and double click on lines in the call stack. This will bring you to the line in question. Now, try to locate the crash somewhere in your code and put breakpoints (F9) before the line which crashes. Then you can step into the code and inspect the variables which are causing problems (here it seems it is a CString which seems corrupted). For instance you can verify that the strings are properly formated and valid pointers.
You can't expect doing any serious software development without using a debugger. When there's a crash like that, your first reflex is to first try to see which information you can extract with the debugger. Then, if you still didn't fix your problem and are still stuck, you can come and ask a question by providing the information from the debugger.

Why are you returning the dead (i.e. out-of scope) variable buf?

His function signature is CString CSMTP::get_response() so the return statement will construct a CString with buf and return it. The problem is not in that construct, it was that buf was not null terminated as expected by the constructor. See previous thread for more
Edit: Just seen that the OP code now initializes buf to empty, so the problem is elsewhere, probably around a call to CMemFile::Free().

Why not set a breakpoint on the first statement in this function and then use the debugger to single-step through the code?

hi friends,
i am a beginner in C++.
Can any one give me an idea about the use of #ifndef and #define ?
