    Default JExcelAPI Error

    Hi guys,

    I need some help here. My program is supposed to read a selected XLS file and it will run the keystroke (auto entering). However, it got the following error:

    Warning: Cannot read name ranges for OLE_LINK5 - setting to empty
    Warning: Usage of a local non-builtin name
    Warning: Usage of a local non-builtin name
    Warning: Usage of a local non-builtin name
    Warning: Usage of a local non-builtin name
    Warning: Usage of a local non-builtin name
    Warning: Usage of a local non-builtin name

    This happened when I enter the range like C30:C50?

    *NOTE*
    fyi: jxl.jar file is needed to run the program.
    My program can only (that is for now. I know there's improvement needed):
    - select range of the same column.
    - able to read till column F.
    - have to close the program and re-run it after doing it once (be it fail or pass).

    I really need this help. I know my coding is not very well done. But I've put in a lot of effort, yet I ended up being told that my program was useless, a failed program. :'( It's very demoralising to be said that way.


    Thanks guys! Really appreciate all helps given!

    Providing a link to the jxl.jar download would of been useful. Not many people are going to go off searching for this..

    As it's a non standard library, this also restricts the replies you will receive.
    Have you tried to Google the error?
