  3. Re: Can a windows external message event return a value?

    Thank you, Michael!

    I had tried a function, but it didn't work--the Windows_override_state was the missing element.

  6. Re: Close File, Open File DAW, THIS IS NOW URGENT

  10. Re: "DF_FILE_ROOT_NAME" or "DF_FILE_LOGICAL_NAME"

    Re: Incorrect Boolean Logic

    I can't help but feel like there is something else going on here. (nNonROCostAmt<>0) is an expression that will evaluate to either true or false, it won't ever evaluate to 0.47. The expression...

    AFAIK the root name and logical name are both stored in FILELIST.CFG, while the field level data (name/type/size) is cached in the .CCH files.
