Hello all, I'm trying to do two tasks which involves some type
conversion, and I'm having dificulties, probably because I
haven't yet understood well how such types works.
First, I wanted to convert UTF-8 strings to ansi, so it displays
correctly at the Windows command prompt. One function to do
that is
"toMBSz" from std.windows.charset, which is declared as follows:
const(char)* toMBSz(in char[] s, uint codePage = 0);
So, after some struggling, I managed to write the following
code:
import std.stdio;
import std.windows.charset;
void main() {
string s = "Testando acentuação";
auto r = toMBSz (s, 1);
writeln (r[0..19]);
}
Although the above code works, I have an impression that it
could be more elegant and concise, but don't know how to
improve it...
I'd also like to play a sound file, so tried to use the
function "PlaySound" from core.sys.windows.mmsystem, declared
as follows: BOOL PlaySoundW(LPCWSTR, HMODULE, DWORD);
According to some error messages I receive, the first parameter
is of
type const(char)*, which corresponds to the sound file name,
but I
just can't figure out how to convert the string (or a char
array) to
that type... Could you please give some snippet example? The
closest I
have come, which doesn't compile at all, is as follows:
import core.sys.windows.mmsystem;
void main() {
char[] f = "C:/base/portavox/som/_fon102.wav".dup;
const(wchar)* arq = cast(const(wchar)*)&f;
void* nulo;
uint SND_FILENAME;
PlaySound (arq, nulo, SND_FILENAME);
}
Thank you,
Cleverson
Cleverson,
About your question related to "Testando acentuação", and
assuming you're using Windows, you can also do the following:
import std.stdio, std.string;
//A Windows function to set the code page of the console output
extern (Windows): private int SetConsoleOutputCP(uint codepage);
void main()
{
SetConsoleOutputCP(65001);
string s = "Testando acentuação";
writeln("Output: ", s.toUpper());
}
Cheers
