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

ANSWER:

Sorry but I have another question .... Sigh | :sigh:

How do I now convert wstring to string,
Cause see I have this function that accepts a std:string and not a std::wstring ... Confused | :confused:

ERROR:
Error 1 error C2664: 'CIniFile::SetValue' : cannot convert parameter 2 from 'std::wstring' to 'std::string' c:\documents and settings\qx55246\my documents\visual studio 2005\projects\testsmsintferface\testsmsintferface\testsmsintferface.cpp 24
Thanx in advance (again)

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.

You need to import valid type library in your project.

You can't: logically it makes no sense. How would the union know which constructor to call?

A union cannot contain a member having a copy constructor.
Revise your design.

Virtual memory usage ? How ?

Dear All,

I want to use virtual memory more rather than main memory.

I need virual memory usage techniques those can be applied for application that has no user interfaces (Dialogs).

Kindly let me know.

Thanks.

Virtual memory usage it's not up to you. OS provides that to applications.
