    MouseWheel event not fired with TImage

    Thanks for your reply, Chris. I've tried compiling under Builder 5 on XP as well as 98 with the same results. (Builder 5 with Borland Service Pack 1) All the indications are that the fault in is C++ Builder 5. I haven't tried compiling under C++ Builder 6 on Win98. I was just surprised that...

    Command Button text ?

    Yes, you can use the \n new line character. This works on a TBitBtn, but not on a TButton. BitBtn1->Caption = "Hello\nThere"; Will display a button Hello There

    MouseWheel event not fired with TImage

    record locking.

    Forgot to say above . . . I held the locking field in a separate table, 1-1 relationship with same primary key, to avoid propagating any additional locking problems.

    record locking.

    I had to deal with this problem, and I used the same method as vbkris. I identified that the system could crash and leave the records in a "locked" state, so ... I allowed the DBA to run a hidden function to clear all the locking fields - note that no one else can be using the Db at...
