64-bit Excel

    Doesn't work in 64-bit Excel.
    Need to add PtrSafe to Declare.

    Thanks for the hint. I'll look into it. Don't have any 64-bit Excel to test it though.

    Hi Huan,

    I prepared a preliminary 64-bit-safe version of the Toolbox. Since I do not have 64-bit Excel, I am unable to test it. Would you like to give it a try?


    It may very well be that some DLL-imported functions do not work and lead to crashes, because it is not always evident which parameters have to be changed to a LongPtr, rather than Long type. So if you try it, please be prepared for crashes at any time and save your work often!

    I found one more DLL call that did not have the required Ptrsafe declaration. This probably prevented the first beta from starting up on a 64-bit system.

    A beta 2 is available here:
