The type initializer threw an exception. - For no reason

Hi,
Im developing a timetable like program which was all working fine until i installed some security updates for windows xp. This might be purely coincidental but i keep getting the exception, pasted below, when i try to call ModPublic.GetSett(). I even removed all code from inside the public modpublic.getSett() sub but i still get this error on each debug/F5 run.

System.TypeInitializationException was unhandled

The type initializer threw an exception. - For no reason

    Hi ReneeC,

    First of all thanks for replying but restoring the computer didnt help. Another thing i rememberd was that VB crashed last time. There didnt see any code problems because it was all saved.

    Could the crash have had effect on some other part like the project file or solution

  • Mark Olszowka

    See how these problems unravel themselves

    We learned that it wasn't the security patches and that the error wasn't for "no reason at all".

    Take care. :)

    Well i was meant to have a on the end of 'for no reason' but i didnt get round to it. Thanks for your help.

  • ChrisParkinson

    I did some commenting out and discovered that the problem was modpublic itself, by then commenting out 'Dim ar as new array_list()' it all worked.

    Thanks anyways

    DarkestShadow,

    Let us hope there is a reason! :)

    I have a couple of recomendations.  I think you need to findout whether the security patches are a coincidence or not. Do you have a recent restore point
    Can you back up to it

    Can you make a restore point now and back the patches out to see if this is the problem or not
