Hi Sam,
here your code snippet with a few modifications to work:
---
module sam;
import std.string;
import std.conv;
import std.c.windows.windows;
extern(Windows)int MessageBoxW(HWND, LPCWSTR, LPCWSTR, int);
int showMessage(in wchar[] msg, in wchar[] caption =
cast(wchar[])"Application", int style = MB_OK|MB_ICONINFORMATION)
{
// return
MessageBoxW(null,to!(const(char)[])(msg),to!(const(char)[])(caption),style);//try
one
return MessageBoxW(null, (msg ~ "\0").ptr, (caption ~ "\0").ptr, style);
//try two
}
void main()
{
showMessage("Message with embedded \u00E4\u00E5\u00F6 european unicode
chars"w);
}
----
Hope this will help you.
Chears,
Sivo
