NinjaTrader 8 Beta 2 PlaySound And Alert Audio wav File Issues

[RJay]

I am unable to play any wav files in the "sounds" folder with either PlaySound or Alert.

It appears that NT8 does not know where its "sounds" folder is.

The help website example below shows that you have to type in an explicit path.

PlaySound(@"C:\mySound.wav");

I put a wav file in the "C:\" location and was able to play that file from an indicator but it played nonstop even though the code is to play only on FirstTickOfBar as shown below.

protected override void OnBarUpdate()
{
if(IsFirstTickOfBar && State != State.Historical)PlaySound(@"C:\beep.wav");
}

When specifying just the wav file name like in NT7, I keep getting error messages:"Please be sure a sound file exists at the specified location.

Please provide info on how to play wave files residing in the sounds folder for both PlaySound and Alerts.



Thanks.

Hello,

I seem to be experiencing the same issue on my end. I'm going to dig into this issue further, and I will post on this thread with any information or updates.

Hello,

After testing further, it appears that you will need to use the entire file path in the current beta release. I will submit a report to our team to look further into the inability to auto-detect the path.

When I used your setup on my end, I did not experience the issue with the sound playing continuously on my end. Can you send me a full export of your code, so that I can test it and see if anything else is coming into play?

Hi Dave,

Please post the code you used to reach the NinjaTrader sounds folder.

Thanks,

This is what I used:

protected override void OnBarUpdate()
		{
			if(IsFirstTickOfBar&& State != State.Historical)
			{
				PlaySound(@"C:\Program Files (x86)\NinjaTrader 8\sounds\Alert1.wav"); 
                        }
			
		}

Keep in mind that while we are still working on this, you can also use NinjaTrader.Core.Globals.InstallDir to dynamically populate the path to the installation directory.

NinjaTrader 8 - Beta 7:

I still need to enter the entire path to the sounds directory to play sounds via Alert().

I'd like to add my two cents...

I had this "problem" too and the way I see it, it isn't a problem. It is the way it is supposed to be. In the release notes, I read somewhere that Ninja 8 is seeking to conform to industry standards. Requiring the entire path and file name to the sound file is the way I think you should leave it. I thought that was an intentional change. I had no idea you did that by accident.

If you make it work both ways - having Ninjatrader assume the Sounds directory in the install dir and also make it accept a path, that would be fine. But forcing the user to code to the Sounds directory in the install dir, is I think wrong. What if my sound files were somewhere else?

This is what I'm using:

string soundFilePath = string.Format( @"{0}sounds\{1}", NinjaTrader.Core.Globals.InstallDir, SoundFileName );
PlaySound( soundFilePath );

Or you could just put pass the whole string.Format() to PlaySound.

Appreciate you observations and you are correct: It was an intentional change for the reasons cited... apologize that the thread was not updated earlier with those conclusions. However we did note that this was not in the code breaking changes, so we will be adding that here shortly.

Fair enough, but let us also remember that in NT7, the ...\Sounds folder was just a default that was applied when the unadorned file name was specified. One could always specify the full path if one wanted to.

Just a correction. It makes no difference to me: I generally specified the full path anyway, even in NT7.

as we created a file-picker dialog.

[traderpards]

we created a file-picker dialog.

That's the best approach. That way the user is in control of everything and the programmer doesn't have to assume or know anything.

Can you give a WPF novice any clues as to how to accomplish that in the Properties dialog?

I've done that in Windows Forms using a class I "borrowed" (somewhere) but I don't have a clue in WPF.

Well, the issue with WPF is that there appears to be no default PropertyGrid, and we must each roll our own. Fortunately, NinjaTrader in NT8, has supplied us with a custom PropertyGrid, and has written an editor for us. They call it the PropertyEditor.

Curiously enough, the internal mechanics may reflect similar thinking, as, as I state in the thread, specifying a mask of *.wav does default the file-picker to the ...\sounds folder. A *.* filter mask defaults to the ...\documents folder.

Interesting that you folks with NT 8 had issues with sound files yesterday. I also did with NT 7 except they were all going off at different times when they shouldn't have been. I closed ALL my charts in all workspaces and the alert sounds just kept going off. LOL

I finally took those four files out of the sound folder to shut them up.

Again thank you for your reply. That definitely solved the problem!
