The most sensible thing to do is try them and see which ones generates the best code for your problem on whatever system they have to run on. Most manufacturers (e.g. Intel and Microsoft) produce free compilers which will be good enough for evaluating how they perform.

By the way, are you looking for a C or for a C++ compiler? People are giving you advices regarding C++ compilers and you are persistently talking of a "C compiler". While each C++ compiler must be able to process C-code and generate C-code binaries, there might be specialized C-compilers for generating fast C-binaries...

You are right paul. Actually, I am looking for fastest free C compiler only, but C++ is also acceptable as it can also compile C code.
As you mentioned, specialized C compiler for generating fast/best optimized binaries would be the best for me.

Hi all,
when i m trying to stop running thread ,than some time exception occur and point out on this location in call stack
> test.exe!CMapPtrToPtr::GetNextAssoc(__POSITION * & rNextPosition=0xfeeefeee, void * & rKey=0xfeeefeee, void * & rValue=0xfeeefeee) Line 294 C++
i dont understand whats going wrong please help me for this.
thanks in advance.

IIRC when you see an object with the bit pattern 0xfeeefeee in VC++ it means the object's been deleted. So my first guess would be you've got a map and and you're trying to delete it twice, or trying to use it for something after it's been deleted.
Cheers,
Ash

Are you trying to stop thread A from within itself, or from some other thread?

i m doing like this.
class CTimerTh :: CWinThread
{
}
class CMy_Th::CTimerTh
{
}
//i create thread with AfxBeginThread and use here CMy_Th as run time class and and save its return pointer in std::map<int, CMy_Th*> ass
ass[0] = (CMy_Th*) AfxBeginThread( RUNTIME_CLASS(CMy_Th),THREAD_PRIORITY_NORMAL, NULL,CREATE_SUSPENDED,
NULL);
std::map<int, CMy_Th*>::iterator pos = ass.find(0);
if(pos != ass.end())
{
if(pos->second!=NULL)
{
CMy_Th* pThread = pos->second;
pThread->PostThreadMessage(WM_QUIT,NULL,NULL);
}
ass.erase(pos);
}
</pre>
please me to resolve the error.
thanks in advance.

See here. I prefer to let threads kill themselves, and use events to signal between them.

hi all,
i m working on SDI type application ,i want to set some minimum size of application.
please tell me how can i do this.
thanks in advance

In your CMainFrame class, you could implement a handler for WM_GETMINMAXINFO like this:
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI)
{
int min_x = ::GetSystemMetrics(SM_CXSCREEN) / 4;
int min_y = ::GetSystemMetrics(SM_CYSCREEN) / 3;
int cx = lpMMI->ptMinTrackSize.x;
int cy = lpMMI->ptMinTrackSize.y;
lpMMI->ptMinTrackSize.x = (cx < min_x) ? min_x : cx;
lpMMI->ptMinTrackSize.y = (cy < min_y) ? min_y : cy;
CFrameWnd::OnGetMinMaxInfo(lpMMI);
}
This example will give you a minimum of 1/4 the screen width and 1/3 the screen height. You could also use hard-coded number of pixels, although this might not scale well for different monitor sizes.

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
cs.cy = 100;
cs.cx = 100;
return TRUE;
}
You can set your custom size with use of cs.cy and cs.cx parameter

Hi all,
i want to calculate time that is taken by execute a function.
i m doing it like this.
DWORD dw = ::GetTickCount();
dw = ::GetTickCount() - dw;
CString time_str;
time_str.Format("%d ms", dw);
AfxMessageBox(time_str);
is it right way to do this.
thanks in advance.

You can get much better resolution with the APIs QueryPerformanceCounter() and QueryPerformanceFrequency(). Use ...Counter much like you use GetTickCount, and ...Frequency to calibrate your results. Hit MSDN for more info and examples.

I have a binary file of size 3GB. I want to reduce the size using some coding in C to write another binary file.
Please suggest/provide a way to write compact binary file.
TO read this file i need to use C#.
Thanks,
Sachin

WinZip(3GB_Filename, 2GB_Filename); ?
Seriously, it depends on what is contained in the 3GB binary file. Is it even compressible?
If it contains lots of NULLS, for example, change the NULL bytes to a single NULL followed by a count of how many there are. A string of 10 NULLS would turn into a single NULL and a byte with the number 10 in it, saving 8 bytes.
Reading the file in, you would simply reverse the process.
1,2,3,4,5,0,0,0,0,0,0,0,0,0,0,1,2,3,a,b,c,0,0,0,0,d,e,0,f,ff
(30 bytes)
Becomes
1,2,3,4,5,0,a,1,2,3,a,b,c,0,4,d,e,0,1,f,ff
(21 bytes)
Alternatively, implement one of the Open Source Zip and Unzip routines in your C and C# code, as appropriate.

check this library.
http://zlib.net/[^]
use following function from library for compress binary file.
deflateInit
deflate
deflateEnd

I've used (libbzip2[^]) in the past with some success at shrinking certain types of binary file. Hopefully there's some repetition in it or whatever you try isn't going to be able to do much to shrink it.

fatal error LNK1104: cannot open file "hid.lib"
please give me any solution.

Check if the file mentioned in the error message("hid.lib") is present or not.
If the file is in some 3rd party libraries installed in system, give the correct path in "Additional include directories" option of your project settings.

This is a library file, not an include file. The folder should be mentionned in "Additional Library Directories".

i've actually meant library path only.. thanks for the correction..

Make sure this file exist on your system and can be found by the compiler (it should either be in the project directory or located in one of the "Additional Library Directory" (project settings -> "Linker" -> "General" -> "Additional Library Directory").
