    First Add On

    I have just added my first AddOn - as a New menu item (see the screenshot).

    This is really cool and already gives me plenty of new ideas for development!

      gregid,

      I keep getting errors with
      NTMenuItem
      NTWindow,

      Is there a "using" you needed to add or is the On-Line instructions wrong?

        The AddOn instruction is simply not complete, look here to implement NTWindow:
        http://www.ninjatrader.com/support/h...ndow_class.htm

        After implementing this you should be fine just commenting out the remaining offending code to get it work for the first time.

          Thanks,

          That didn't seem to resolve my issue "The type or namespace 'NTWindow' could not be found (....)".

          I will have to wait for better documentation or an example.

              I could have swarn I tried adding this line:
              using NinjaTrader.Custom;
              using NinjaTrader.NinjaScript;

              NT Support, this is missing from the ADDON template.

              Thank you gregid.

              EDIT: looks like 2 using statements are missing.

                Thanks for the report, we'll have that fixed - NTEIGHT-8213

                I'm attaching a sample addon made by NinjaTrader_Jesse which has some more thorough inline comments which may assist with creating a custom window and implemented the tab features, etc.

                Please expect updates to our AddOn documentation in the next few weeks.

                    Also just noticed, and not sure if it's been brought up before.. Starting to loose track of everything I've read.. But would be nice to be able to select a directory tree from the top of the import form, vs to have to manually add the path and/or go thru the hoops of all the clicking..

                      I haven't seen it yet but meant to bring it up as well. The file selector dialog box could use some work. It is a pain to move to a different Drive & Path to find the file of interest. Is there still a "FileDialog()" box that can be called from the system level? A quick check on MS website shows that was a WinForm dialog. Here is a C# version, not sure if it has the same feel of it NT8 is already using it:
                      http://www.c-sharpcorner.com/uploadf...dialog-in-wpf/
                      http://stackoverflow.com/questions/3...pf-application

                      This seems to be a problem for most WPF applications... Most people recommend using the older FORMs version.

                        We had some design requirements to develop our own file loading dialog, and anticipated some feedback in this area to indicate there should be some improvements. We'll be reviewing this feature in the near future - SFT-41

                          I've been using the SampleAddon provided as a basis in post #8 of this thread, and have run into a problem with threading i don't understand.

                          Using the "marketData_Update" method as provided in the example to update the label content works fine. But if I try to update label content in the "SelectedAccount_ExecutionUpdate" method (again provided in the example) I get a threading error.

                          Ideally I'd like to update labels from that method, as well as a separate timer method (which I haven't tried yet).

                          This probably reflects my lack of knowledge of multi-threading, but can you say why I'm getting this error, and point me in the right direction to fix it?

                          Thanks.

                            Thank you for writing in.

                            Can you please provide your modified script demonstrating this issue so I may test on my end?

                              If I edit the XAML, what do I need to do to refresh the interface? I've tried reopening the add-on, reconnecting NT, restarting NT, logging back in to windows, restarting windows, making sure the XMAL file is saved and closed. I also tried hitting F5 in the addon, but I'm not sure that would do anything. Thanks...BTW, I've renamed the XMAL file, as well as the calling reference in the addon.
