How to convert string into LPCWSTR

Hii

How can I convert string into LPCWSTR

Code:

---

struct FILELIST 
 {
 string path;
 vector<string> theList;
 };


string path
list<FILELIST>& theList

struct _finddatai64_t data;
      string fname = path + "\\*.*";
      long h = _findfirsti64(fname.c_str(),&data);    //_findfirsti64(string,)



---------------

//here I wanna convert string to LPCWSTR  ....

//using the LPCWSTR  I've to open the file using Createfile()

---

I've changed string to wstrig ,that time _findfirsti64() must have string argument...!!

any idea....


Thanking you..

1) Call CreateFileA().

2) Convert your string from whatever encoding it is in (presumably ASCII or UTF-8) to UTF-16. You can use MultiByteToWideChar() to accomplish this. Call it first with the last two arguments set to NULL and 0, respectively, and it will give you a buffer size. Allocate that buffer, call it again but passing the buffer, and you've got an LPWSTR. Then call CreateFileW(). Don't forget to free your memory.

Use a vector<WCHAR> if you convert yourself. But using CreateFileA is a better idea.
