Exception thrown when trying to get ApplicationID(s)

[c3rebro]

Dear ISLOG team,

when i try to list the Apps on a blank DesFire EV1 chip with
List vector = new List();
vector.Add(Convert.ToInt16(dcmd.GetApplicationIDs()));

i get an error like:

System.Runtime.InteropServices.SEHException (0x80004005): An external
component throws an exception.
at LibLogicalAccess.IDESFireEV1Commands.GetApplicationIDs()

could you please lead me to the right direction?

Thanks, Steven.

Ok there was an issue with GetApplicationIDs and GetFileIDs located in COM wrapper. It should be fixed now.
Could you try again after replacing liblogicalaccess.com.dll located under %CommonProgramFiles%\ISLOG\LibLogicalAccess\1.68.0913\ by this one:
http:https://download.islog.com/liblogicalaccess/tests/liblogicalaccess.com.dll-1.68.0913.2

And let me know if it fix the problem. If so it will be fixed in 1.69 release.

unfortunately i've missed to mention i have a x64 system. do you have a x64 release of 1.68.0913 .com.dll ?

this one is 32bit and returns the following error when trying to intatiate:

IReaderProvider readerProvider = new PCSCReaderProvider();

800700c1 is not a valid Win32-Executable. (Exception from HRESULT: 0x800700C1).

Ok I recreated the full installer.
Please uninstall current LibLogicalAccess 1.68 installer and install this one: http:https://download.islog.com/liblogicalaccess/tests/liblogicalaccess-exe-1.68.0916.zip

Thanks for your time!

But iam sorry to say it did not work.

I've uninstalled Build 0906 and installed 0916. I deleted interop.liblogicalaccess.dll from my project folder to ensure the new build is used. The Error Message is still the same like above.

I also tried the following Methods wich all seem to has worked (as i partially has checked the card contents with a self created "GetApplications()" method using winscard.dll):

dcmd.CreateApplication(0x332211,DESFireKeySettings.KS_FREE_CREATE_DELETE_WITHOUT_MK,5);
dcmd.SelectApplication(0x332211);
dcmd.Authenticate((byte)0,deskey);
dcmd.GetKeySettings(out keySettings, out maxNbKeys);
dcmd.ChangeKeySettings(keySettings);
dcmd.DeleteApplication(0x332211); (after auth to master application)
dcmd.Erase(); (after auth to master application)

Indeed, the error still occurs in some cases. I'm investing the problem.

Ok the error was wrong memory allocation for application id list. Depending the number of Application IDs on your card, it was working or crashing. This is now fixed.
You can test it on current development version if you want (you will need to update your project reference to LibLogicalAccess 1.69): http:https://download.islog.com/liblogicalaccess/liblogicalaccess-exe-1.69-SNAPSHOT.zip

Indeed, it now does work!

I used:

...
object appIDsAsObject = dcmd.GetApplicationIDs();
UInt32[] appIDsAsArray = (appIDsAsObject as UInt32[]);
...

Thank you very much.
Nice Project btw.

Greetings from Germany,
Steven.
