aufnahme von wavdateien mit callback function

N

nullstring

Hallo Leute,
gerade sitze ich vor dem problem, das ich eine
Klasse schreiben muss dir mir ne Wav datei vom mikro aufnimmt und
wieder abspielt.

Mein Problem ist nun, das mir meine callbackfunction nie ein
MM_WIM_DATA liefert
und augenscheinlich auch nix aufnimmt.

Tja und wie es halt so ist, bin ein newbie was Winprogrammierung
angeht.
vielen dank schonmal


ich verwende folgenden code

Hello people,
just I sit before problem, which I one
Class must write to you to me ne Wav datei from mikro takes up and
again passes the ball.

Now my problem never is, to me mine callbackfunction one
MM_WIM_DATA delivers
and seemingly also nothing takes up.


Well and how it is just in such a way, am newbie what Winprogrammierung

it begins.
to many thanks to schonmal


I use following code

Hello of people, straight I sit before the problem, which I must write
a class you me ne Wav file of the micro take up and again play. My
problem is now, which to me my callbackfunction never a MM_WIM_DATA
supplies with and apparently also nix takes up. Tja and like it stop
like that is, is newbie which Winprogrammierung concerns. thank you
already times I use the following code :

Hello people
exactly, I sit before the problem, that I one
Class must write me ne Wav file you from the micro picks up and
passes again.

My problem now is, that never me my callbackfunction in one
MM_WIM_DATA delivers
and evidently also nothing picks up.

Well and as it is just so, is a newbie Winprogrammierung something
come on.
much thanks to already-once
I use following code

Please, have a look to some Windows API conference (maybe in german
language or ask in english).

Du bist hier ziemlich falsch. Für deutschsprachige C++-Fragen wäre
de.comp.lang.iso-c++ besser geeignet, aber du kannst dir das Posten dort
sparen, da die Frage dort genauso off-topic ist wie hier. Beide Newsgroups
beschäftigen sich ausschließlich mit der Sprache C++, wie es von ISO/IEC
14882 definiert wird, und dort gibt es keinerlei Audio-Funktionalität.
Deine Frage ist Windows-spezifisch und sollte daher in einer Newsgroup über
Windows-Programmierung gestellt werden.
