Modifying wchar_t

[enigmatix]

Hey guys,

Im attempting to modify a wchar_t but i get an access violation error. For example:

wchar_t* str = new wchar_t[30];
str = L"Hello!";

str[2] = L'A'; // Access violation error?

Why is this happening?

Line 3 creates a memory leak. You are reassigning the pointer from something you newd to a const wchar area, so when you try to modify it, you can't. You need to use a strcpy() like function (I don't know if there are ones for wchar_t though).

Windows provides them.

#include <windows.h>
...
wchar_t* str = new wchar_t[30];
lstrcpyW( str, L"Hello!" );

Hope this helps.
