Hello! Im a Newbie and I have the same prob like the most newbies in this forum.
I will play a MP3 file with the newest Version of FMOD and so i write my sourcecode but when i compile it (with VB.Net and the Standard .bas file wich i have convert VB.NET conform.) i get a Problem.
I have a Problem when i call the FMOD_SYSTEM_CREATESTRaEM Function i get any time an result 33 and the message: invalid Parameter…
i have no Idea how i can fix the problem. I have read every message to this topic in the forum and i have ask google to this but nothing help me.
I have checked that exinfo.cbsize = 76 all aothers are 0 and my Variables will be correct so i Think.
Here is my code for this :
Dim sys As New Long()
Dim sou As New Long()
Dim exi As New Long()
Dim cha As New Long()
Dim Result As FMOD.FMOD_RESULT
'///////////////Check FMOD - Functions on Errors/////////////// Private Sub Errorcheck(ByVal Res As fmod.FMOD_RESULT) If (Res <> fmod.FMOD_RESULT.FMOD_OK) Then MsgBox("FMOD - Error! " + CStr(fmod_errors.FMOD_ErrorString(Res)) + "", MsgBoxStyle.Critical, "Error") End If End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load sys = 0 sou = 0 cha = 0 '///////////////FMOD - Create Main Object/////////////// Result = FMOD.Factory.Create(sys) Errorcheck(Result) '/////////////// Set the output to Stereo./////////////// Result = FMOD.System.FMOD_System_SetSpeakerMode(sys, FMOD.FMOD_SPEAKERMODE.FMOD_SPEAKERMODE_STEREO) Errorcheck(Result) '///////////////Allow 100 software mixed voices to be audible at once./////////////// Result = FMOD.System.FMOD_System_SetSoftwareChannels(sys, 100) Errorcheck(Result) '///////////////Require the soundcard to have at least 32 2D and 3D hardware voices, and clamp it to using 64 if it has more than this.////////////// Result = FMOD.System.FMOD_System_SetHardwareChannels(sys, 32, 64, 32, 64) Errorcheck(Result) '///////////////Initialize FMOD with 200 virtual voices./////////////// Result = FMOD.System.FMOD_System_Init(sys, 200, FMOD.FMOD_INITFLAGS.FMOD_INIT_NORMAL, 0) Errorcheck(Result) Result = FMOD.System.FMOD_System_CreateStream(sys, "1.mp3", FMOD.FMOD_MODE.FMOD_LOOP_OFF, sou) Errorcheck(Result) /* here i get the negetive message. Result = FMOD.System.FMOD_System_PlaySound(sys, FMOD.FMOD_CHANNELINDEX.FMOD_CHANNEL_FREE, sou, False, cha) Errorcheck(Result) End Sub[/size][/code:tv3f8u4l]
FMOD.xxxxxxxxx came from my convert and i have also the next classes like System and Sound for example in diffrent sub Classe pressed.
When you need my fmodex.bas and the other files then write a message i have now no Webspace and i dont find annything to upload this files and i wouldnt post it its a little nit big for this.
Plase try to help mee i have no Idea.

I don’t think i have to open a new thread so i post my problem here..
I want to check each frame if my song is still playing or not.
Thatfore i have a method in my class:
inside the class as private:
playing the sound in a method with:
[code:18n0fxhp]MORK_Result = FMOD_System_PlaySound(MORK_System, FMOD_CHANNEL_FREE, this->sample, true, &(this->channel));
checking if sound is playing:
(this is called before the FMOD_System_Update)
FMOD_BOOL active = 0;
MORK_Result = FMOD_Channel_IsPlaying(this->channel, &active);
if ((MORK_Result != FMOD_OK) && (MORK_Result != FMOD_ERR_INVALID_HANDLE) && (MORK_Result != FMOD_ERR_CHANNEL_STOLEN))
So the timeline is:
next frame (system update)
until sound ends
next frame (system update)
isplaying throws FMOD Error (33) Invalid Parameters
if i do the system update before the isPlaying-method is called again, i get the error one call earlier…
what happens with my counter var when the song stops?
first its a 0, then i get an address and after the stop? it looks like it stays at the address.. and how do you check if the sound stopped?
can’t get behind this…
is there any way to implement the callback as method in my class?
i always get [quote:1c8mfd30]argument of type
FMOD_RESULT (MORK_SAMPLE::)(FMOD_CHANNEL*, FMOD_CHANNEL_CALLBACKTYPE, int, unsigned int, unsigned int)'FMOD_RESULT ()(FMOD_CHANNEL, FMOD_CHANNEL_CALLBACKTYPE, int, unsigned int, unsigned int)’ [/quote:1c8mfd30]
does not match
but if i make it as global function i get[quote:1c8mfd30]invalid conversion from
FMOD_RESULT (*)(FMOD_CHANNEL, FMOD_CHANNEL_CALLBACKTYPE, int, unsigned int, unsigned int)'FMOD_RESULT ()(FMOD_CHANNEL, FMOD_CHANNEL_CALLBACKTYPE, int, unsigned int, unsigned int)’
initializing argument 3 of
`FMOD_RESULT FMOD_Channel_SetCallback(FMOD_CHANNEL*, FMOD_CHANNEL_CALLBACKTYPE, FMOD_RESULT ()(FMOD_CHANNEL, FMOD_CHANNEL_CALLBACKTYPE, int, unsigned int, unsigned int), int)'[/quote:1c8mfd30]
so… where is my mistake?
[code:1c8mfd30]MORK_Result = FMOD_Channel_SetCallback(this->channel, FMOD_CHANNEL_CALLBACKTYPE_END, MORK_Callback, 0);
FMOD_RESULT F_CALLBACK MORK_Callback(FMOD_CHANNEL *channel, FMOD_CHANNEL_CALLBACKTYPE type, int command, unsigned int commanddata1, unsigned int commanddata2)
sometimes.. im just to stupid for this..
i got it all solved.. thx so far
