Mr.Wizard Posted November 10, 2004 Share Posted November 10, 2004 According to the page you gave the URL to, that API call takes two parameters and in your example code you've only given it one...

silvanr Posted November 10, 2004 Author Share Posted November 10, 2004 I don't understand This. Sorry. Can you give me an example please? Thanks Sorry, which my English is so bad. I come from Switzerland ;-) Link to comment Share on other sites More sharing options...
Mr.Wizard Posted November 10, 2004 Share Posted November 10, 2004 It would be something like $err = DllCall("Winmm", "int", "waveOutGetVolume", "int", 0, "long", $vol) but I've just tried it and it doesn't seem to work... Does anyone else know whether you can pass values by reference to dlls using dllcall? Cos that's what would need to happen for this particular API call to work... I have a catapult.

silvanr Posted November 10, 2004 Author Share Posted November 10, 2004 $err = DllCall("Winmm", "int", "waveOutGetVolume", "int", 0, "long", $vol) Return: $vol = "" ;empty string :-( $err[0] = 11 $err[1] = 0 $err[2] = 0 But I would for $vol a value (0 - 100) Sorry, which my English is so bad.
