using own dll

[whatsup]

I know that, and I have done all.

In this DLL, I have module where I have directX functions, and in DLL I used reference quartz.dll.

Description of problem.

I want to use two sounds at the same time. First, I set module inside application. But if I want to load secund file, first will be replaced. And I can't play it. So, I decided to move that module in one DLL, so i can declare two object, Music1 as MyDll.clsPlay, Music as MyDll.clsPlay.



Using this DLL, I can't accomplish this task

for your first problem :
play more than one file at a time:

Type DirectShowbuf
    Event As IMediaEvent
    Control As IMediaControl
    Position As IMediaPosition
    Audio As IBasicAudio
    Video As IBasicVideo
    Video_Window As IVideoWindow
End Type

Function DSInit(DS As DirectShowbuf) As Boolean
    On Error GoTo Error_Handler
    Set DS.Control = New FilgraphManager
    Set DS.Event = DS.Control
    Set DS.Position = DS.Control
    DS.Position.Rate = 1
    DSInit = False
    Exit Function
Error_Handler:
'    Call ShowErrorMsg()
    DSInit = True
End Function

you can use this last function to open as many devices as you want,
and thus play as many files as you want.
you should be aware what you're doing, because you need also to close those
devices.
you can for examples use an array to store each device, like this:

Dim DSArray[10] As DirectSHowBuf
Dim DSDeviceNum As Integer

Private Sub Form_Load()
  For DSDeviceNum = 0 To 3
    Call DSInit(DSArray(DSDeviceNum))  
    DSDeviceNum = DSDeviceNum + 1
  Next

  For DSDeviceNum = 0 To 3
    DSArray(DSDeviceNum).Control.RenderFile (fName)
  Next
End Sub
