    JIT Compilation for win form app

    I am working on a win app, and when testing it, I encounter an error that
    results in a dialog opening and giving me a generic error (object ref not
    set to instance of an object or the like). It doesn't tell me what the ref
    or obj is, and doesn't give me a line number. Isn't this part of JIT??? I
    get that when working in ASP.Net apps.

    I am building it in debug mode.

    My Machine.config file in 1.1 is updated to inclue <system.windows .forms
    jitDebugging="t rue" />, but that had no effect. There is no
    Applicaiton.con fig file that I can find that is generated by studio... if it
    exists, does it superceed the setting is Machine.config?

    Isn't studio considered a JIT Debugger? I guess I don't understand. ;-)

    Thanks,

    MCD

      No, it's running your code and finding a null reference to an object.
      Compile the code, before you run it, press CTLR + ALT + E, then Alt + B,
      then Enter. That will stop you at the point of exception. To remove:
      CTLR + ALT + E, then Alt + O, then Enter
