LPWSTR to string

Question

How to convert LPWSTR into string??

Answer 1

Into what kind of specific string?  Can you give some code samples?

Answer 2

yes...

string temp;
LPWSTR str1 = L"sometext";

Now i want some procedure to take content of str1 into temp.

Answer 3

string MyString = CW2A (L"sometext");

Also, consider using wstring instead of string.

Answer 4

Yes, I would also suggest using wstring.  I believe you have the potential to lose data based on what language you are using or at least member functions of the string type will not function correctly.

Answer 5

 Ok.... Now i explain , what actually i need..
I am useing Net API.. and following network mgmt structure.

typedef struct _SERVER_INFO_101 {
  DWORD sv101_platform_id;
  LPWSTR sv101_name;
  DWORD sv101_version_major;
  DWORD sv101_version_minor;
  DWORD sv101_type;
  LPWSTR sv101_comment;
} SERVER_INFO_101,
*PSERVER_INFO_101,
*LPSERVER_INFO_101;

So there is one function in my code that accept parameter of type "string".
I want to pass   LPWSTR sv101_name to that function.

So in this case , how can i convert    sv101_name (which is of type   LPWSTR ) into string.

Answer 6

The basic_string constructor can build a wstring from a null-terminated string.

E.g.

wstring str(L"Foo");

Answer 7

i want to build null terminated string from wstring

Answer 8

I think you're confused.

But to answer your question, the basic_string::c_str() member gives you a null-terminated string from a basic_string.

E.g.

wstring str(L"Foo"); // build a basic_string

const wchar_t *szFoo = str.c_str(); // and reverse the process

Answer 9

If you don't like CW2A, you could use WideCharToMultiByte() or wcstombs().
