A self-reliant programmer, certainly. The trick is remembering that things actually exist, so you know to look for a solution rather than try to re-invent the wheel.

i use VS2005
today i programe a .cpp File to learn "Template"
the source code is:
<br />
#include<iostream><br />
using namespace std;<br />
<br />
template<typename Type><br />
<br />
Type min(Type a,Type b)<br />
{<br />
return a<b?a:b;<br />
}<br />
<br />
int main()<br />
{<br />
int a = 0, b = 1, c = 3;<br />
<br />
c = min<int>(a,b);<br />
<br />
cout<<c;<br />
}<br />
but when i run the result is show wrong can somebode help me

What is the result you have and what did you expect ?
|
|
|
|
|
compiler error the message is
error C2668: “min”:

Not very usefull reply... 
Anyway, you don't have the error when you run but when you compile then ? That's something completely different.
The problem probably comes from the fact that min already exists (I think). Try using another name or putting the function in a specific namespace.

|
|
|
|
oh....yes
i think you are right when i using another name is can run and no error
thanks

Let's be more accurate - that's part of the message...this is the message I get from your code:
error C2668: 'min' : ambiguous call to overloaded function
a.cpp(6): could be 'Type min<int>(Type,Type)'
with
[
Type=int
]
C:\Program Files\Microsoft Visual Studio 9.0\VC\INCLUDE\xutility(3397): or 'const _Ty &std::min<int>(const _Ty &,const _Ty &)'
with
[
_Ty=int
]
while trying to match the argument list '(int, int)'
It helps when a) programming, or b) asking questions about programming, to get all the details correct and in place...

When you run what?
As I expected, you get a compiler error when you try and compile that code, because the standard library already defines a template min function. You need to specify which min you want, by specifying that you want the 'no namespace' version (for that is yours) like this - oh, and you don't need to specify template parameters for functions if the function argument's types unambiguously specify the template parameters:
c = ::min(a, b);
Oh - and using namespace std; is bad form - use a using declaration instead. In your case, that would be 'using std::cout'. Those changes leave your program like this:
#include<iostream>
using std::cout;
template<typename Type>
Type min(Type a,Type b)
{
return a<b?a:b;
}
int main()
{
int a = 0, b = 1, c = 3;
c = ::min(a,b);
cout<<c;
}

I tried using shared pointer in VS 2008 trial edition(Team suite) in a Win32 application,
#include "stdafx.h"
#include <memory>
int _tmain(int argc, _TCHAR* argv[])
{
std::tr1::hexfloat //Only this comes in tr1 namesspace
std::tr1::shared_ptr sharedPtr;
//std::tr1:: error C2039: 'shared_ptr' : is not a member of 'std::tr1'
return 0;
}
It’s supporting auto_ptr but not shared_ptr. Is the problem in my coding or because of trial version.

Could be the trial version - I seem to remember tr1 only got added to VS2008 in service pack 1 or with the Visual C++ 2008 Feature Pack[^].
Anyway - std::tr1::shared_ptr works fine for me on VS2008 with service pack 1 installed.
PS - you'll need to tell shared_ptr (as a template parameter) what type it's pointing at!!!

Hello I want to read from com port1, and I used API
if (WaitCommEvent(hSerial, &dwCommEvent,NULL))
{
if (dwCommEvent & EV_RXCHAR)
{
DWORD dwNumberBytesRead;
if(ReadFile(hSerial, chRead, sizeof(chRead),&dwNumberBytesRead,&osReader))
I have got an extra Thread to read com port but if data is not send to port my program hangs up.
Is there any way to check if input buffer is changed and then ReadFile instead waiting for
WaitCommEvent ??, or if there is some other ways?
Thanks in advace

When I've programmed serial ports, I've not used WaitCommEvent - I've set a timeout period with SetCommTimeouts[^] and just used ReadFile. If the serial port receives data or times out, then ReadFile returns successfully and will tell you how many bytes it received (0 probably indicates a timeout).

I want to convert a cstring into LPBYTE but each time i convert it only first character get stored in the LPBYTE and rest of the string is truncated.
Thanks

First important point: why do you want to do such a thing ? Are you aware about unicode/non-unicode ? If not, I highly suggest reading this article[^] before going further.
Post also your code to see what you are doing wrong.
