#1 Burning Software

Hello Dima Sir,

I am getting following Debug Assertion failed problem on almost every Operating System. This occurs when I call StarBurnX.Refresh() function.

Hello,

1) Do you use the latest update of StarBurnX - #20100224?
2) Do you call the refresh method from main thread?

Regards,

Dmitry

Hello Sir,
1) Yes, I am using latest dlls.
2) But, Sir I had to call StarBurnX.Refresh on thread. Because it takes a lot of time for this process, so I had to show a progress dialog.
I any thing wrong with that?

Your application is .NET application?

Dmitry

Yes Sir. My application is .NET application.
I am using StarBurnX & referring VB.NET samples.
Thank you.

Ok, we will check it at weekends!

Hello,

We have checked this problem ... it seems that all ok :) This assertion means that collection was modified during the iteration process!

You should wait till the refresh process finished and then iterate through collection of devices!

Thank you Dima Sir,
I will modify my whole refresh logic to avoid this problem (will try to call refresh on main thread).

Hello,

NO NO!! You CAN call the refresh function from user( non main ) thread!!!

You should manually synchronize access to collection of drives!!!

For example:

Private Shared waitHandles() As WaitHandle = {New AutoResetEvent(False)}

' This function will be called from the user thread
Sub DoRefresh(ByVal state As Object)

'.. USER THREAD ...

Dim are As AutoResetEvent = state

m_starBurnX.Refresh()

' Notify about success
are.Set()

End Sub

...
Yourfunction()

'... MAIN THREAD ...
Dim refreshThread As Thread = New Thread(AddressOf Me.DoRefresh)

' Start refreshing
refreshThread.Start(waitHandles(0))

' Wait till the "Refresh" tread notified about success
WaitHandle.WaitAll(waitHandles)

'Get collection of drives and Refresh combobox
...

Dmitry
