Hi all,

How can i convert a TCHAR to a string?

for example:

<code>
TCHAR  infoBuf[INFO_BUFFER_SIZE];
GetComputerName( infoBuf, &bufCharCount );
string pc;
... convert / assign the value of infoBuf to pc ...
</code>

Many Thanx

Hi,

There is no needed any conversion:

pc.assign( bufCharCount );

should work fine.

ok, you use VS2005 (I've just noticed it). There is UNICODE by default.
TCHAR is defined as a wchar_t and to cooperating with it is std::wsting.

If you really need convet it, you can use e.g. wcstombs or W2A

I would suggest some modifications to your code,

	TCHAR  infoBuf[INFO_BUFFER_SIZE];
	DWORD  bufCharCount = INFO_BUFFER_SIZE;	
	GetComputerName( infoBuf, &bufCharCount );
	string a;
#ifdef UNICODE
	size_t i;
	char temp[INFO_BUFFER_SIZE];
	wcstombs_s(&i,temp,(size_t)INFO_BUFFER_SIZE,infoBuf,(size_t)INFO_BUFFER_SIZE);
	a.assign(temp);
#else
	a.assing(infoBuf);
#endif

One more way to achieve this. Save one function call,too.

TCHAR  infoBuf[INFO_BUFFER_SIZE];
GetComputerName( infoBuf, &bufCharCount );
basic_string<TCHAR> pc(infoBuf);

Thnx Prasad,

But my fubction accepts a std::string and when I do this:

TCHAR  infoBuf[INFO_BUFFER_SIZE];
GetComputerName( infoBuf, &bufCharCount );
basic_string <TCHAR> pc(infoBuf);

this would happen:

Error 1 error C2664: 'CIniFile::SetValue' : cannot convert parameter 2 from 'std::basic_string<_Elem,_Traits,_Ax>' to 'std::string' c:\documents and settings\qx55246\my documents\visual studio 2005\projects\testsmsintferface\testsmsintferface\testsmsintferface.cpp 32

If your language/tool supports WideCharToMultiByte and MultiByteToWideChar functions, you may use them for ASCII<->UNICODE string conversion.

Hope this helps.
