    Memory access errors

    I have a vb6 dll which Im referencing in vb.net.

    All seems fine until I close the form and then I get the message

    'the instruction at 0x61a91157 referenced memory at
    0x00000000. The memory cannot be read.'

    The dll is using arrays of a structure, to hold file positions and a sortcode. The dll returns a tab delimited string indicating whether the sortcode is valid or not. I have 2 text boxes(to input sortcode and account number) on the form and a button to validate the details entered.

    Does anyone have any ideas at all???

    Thanks for your help in advance

    Yeh I did that as well. I think its something to do with the garbage collection not freeing up the memory straight away.
    I ended up upgrading the DLL into .net and amending a few things and its working fine.
    Thanks for your help anyway.
