MessageBox shows infinitely

[Vincere]

Hi,

I developed an indicator and I wish it could play a sound and show a pop up message on certain condition.
The sound works but the message shows up in infinite loop.

Here's my code:

if (CurrentBar != savedBar) // if current bar is NOT equal to the savedBar
                {
                    PlaySound(NinjaTrader.Core.Globals.InstallDir + @"\sounds\Alert4.wav");
                    MessageBox.Show("This is an OnBarUpdate() test", "Testing OnBarUpdate()!");
                    savedBar = CurrentBar; // save the current bar here to make them equal
                }​

I'd like the pop up to overlay everything I have opened if it is possible.

Thanks,

Hello Vincere,

Thank you for your post.

It appears you are using the Microsoft MessageBox object. There is also a NinjaTrader message box called NTMessageBoxSimple that you could test out to see if it achieves your desired result:

As for the infinite loop, I suggest adding a Print statement to check the values of CurrentBar and savedBar to verify if the condition might be triggering multiple times. Here is an example of a print statement you could add both outside of your condition as well as inside of your condition:

Print(String.Format("{0} CurrentBar: {1} savedBar: {2}", Time[0], CurrentBar, savedBar));
