NeroCom doesn't work - Club CDFreaks

gerhard_pichler · 12-04-2004

Hi!

I try to burn CDs with NeroCom.dll, but it doesn't work.

Nero is installed properly and here is the code, where an exception occurs:

Code:

NEROLib.NeroClass nero = new NEROLib.NeroClass();
NEROLib.NeroDrivesClass drives = nero.GetDrives(NEROLib.NERO_MEDIA_TYPE.NERO_MEDIA_CD);

In the second line the following exception occurs:

System.InvalidCastException: QueryInterface für Schnittstelle NEROLib.INero fehlgeschlagen.
at NEROLib.NeroClass.GetDrives(NERO_MEDIA_TYPE lVal)
at ........

What's wrong with my code?

Thanks!

I assume this is C# ? In VB.NET one could write:

Code:

        Dim drives As NEROLib.INeroDrives
        drives =  nero.GetDrives(NEROLib.NERO_MEDIA_TYPE.NERO_MEDIA_CDR)

Try something similar in C#. Although I am not very familiar with C#, I don't see a reason why your code would give you an error.

I had the same problem. In my PC (nero 6.6.0.13) all was ok, in another your message appared in the first line of code using nero (nero.APIVersion). In the test PC there was Nero 6.6.0.6, i've upgraded it and now it's all fine.
