Hi,

Is there a way to convert a wchar* variable to char[]? I'm trying to use the
Win32 API LoadStringW, wich takes a parameter a wchar*.

Thanx.

 Hi,

 Is there a way to convert a wchar* variable to char[]? I'm trying to use 
 the Win32 API LoadStringW, wich takes a parameter a wchar*.



So, you have a function that takes a wchar*, and you have a wchar*.

..

I'm not seeing how char[] comes into this at all.

Assuming that `src' is a wchar* string, in Phobos it's like this:

  import std.utf;
  extern(C) uint wcslen(in wchar* str);	// a C runtime library function

  char[] str = toUTF8(src[0..wcslen(src)]);

In Tango, this would be:

  import tango.text.convert.Utf;
  import tango.text.Util;

  auto len = indexOf(src, '\u0000', uint.max);
  char[] str = toString(src[0..len]);

I would do like this:

Phobos:

import std.string;
import std.utf;

// alias for char[] (D 1.x)
string str = toUTF8(toString(src));

Tango:

import tango.stdc.stringz;
import tango.text.convert.Utf;

char[] str = toString(fromString16z(str));

In Phobos, there is no function "std.string.toString(wchar*)".
