convert string into LPCWSTR

[krishnampkkm]

string source;

	 char *src = (char*)(source.c_str());
	 LPCWSTR lpszsrc = (LPCWSTR)src;

       Handle h=  CreateFile(lpszsrc,.........);

       if(h==INVALID_HANDLE)
       printf("Error occured")
       return 0;

The above code segment always shows invalid file handle.I know the reason is my LPCWSTR conversion is not correct.How to make it correct.?

There's no need to call the unicode mapping by calling CreateFile and having to go through the conversion.

Instead call CreateFileA( ) for the ANSI version.
Also use
INVALID_HANDLE_VALUE for the return value check!

You can also gointo the project settings and turn off UNICODE and set to Single Byte or Multi-Byte.

I solved theabove problem

string source;
CString src( soure.c_str()) ;
