error alert boxes

[franatas]

When an addon gives me an error, how can I get Ninja to send me an alert box to notify me, just like the null object exception boxes?

Hello franatas,

Thank you for your post.

You can use try/catch blocks to trap exceptions.

Please see the example script below:

https://ninjatrader.com/support/helpGuides/nt8/using_try-catch_blocks.htm

Within try/catch block, you can use Log() to write a message to the Log with notification window with LogLevel.Alert:

Or an alert:

Please see this Help Guide page on Alert and Debug concepts:

If you have any further questions, please let us know.

This is fine but I am referring to the pop-up windows with messages

Hello,

To show a pop up error window, you can use NTMessageBoxSimple.Show().

Please let us know if you have any other questions.

Hello,

Please see the attached sample script demonstrating using the message box. Are you using an indicator or a strategy?

Note: for the test script make sure to check ShowBox in the properties to get the box to pop up.
