reduce characters from LPWSTR and save it as LPCWSTR

I have开发者_开发知识库 a string saved as LPWSTR. I have to make a change in this string (reduce some characters) and save it as LPCWSTR. How can i do it?

Thanks

An LPWSTR is just a pointer to an array of WCHARs, which represent UTF-16 code units. Iterate through the characters, much like you would a char *, making the change you need. You might want to edit your post and explain exactly what change you need...

An LPCWSTR is just the const version of LPWSTR. (A LPWSTR is a WCHAR * and a LPCWSTR is a const WCHAR *.)

An LPWSTR can be modified (no C in there). Just use std::remove_if() or any other function you'd like. You can then simply const_cast<> the pointer to a LPCWSTR.
