Serialization - no help

[Mindset]

I am getting the message

Indicator ..... could not be serialized.
Please refer help for more information on serializing indicators.


Which is fine .... except that I can't find anything about serialization in the help!!

Sometimes it's just not easy using NT.

Sorry for the frustrations Mindset, please see this tip here showing custom serialization of color inputs as an example - http://www.ninjatrader.com/support/f...ead.php?t=4977

List

Can't NT give us a list of serializable classes?

List of Serializable Objects

I can't give you a complete list. But after an exhaustive search thru the Ninja Classes in v6.5 I discovered the following. Nijja 7.0 may have a few more, but I've not gone looking since it shipped,

1. Color

 
[FONT=Courier New][SIZE=1][COLOR=black]public [/COLOR][COLOR=red]Color[/COLOR][COLOR=black] PaintColor[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]{[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]  get { return paintColor; }[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]  set { paintColor = value; }[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]}[/COLOR][/SIZE][/FONT]
 
[FONT=Courier New][SIZE=1][COLOR=black][Browsable(false)][/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]public string PaintColorSerialize[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]{[/COLOR][/SIZE][/FONT]
[FONT=Courier New][SIZE=1][COLOR=black]  get { return NinjaTrader.Gui.Design.[COLOR=blue][B]SerializableColor[/B][/COLOR].ToString(paintColor); }[/COLOR][/SIZE][/FONT]
[COLOR=black][FONT=Courier New][SIZE=1]  set { paintColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }[/SIZE][/FONT][/COLOR]
[COLOR=black][FONT=Courier New][SIZE=1]}[/SIZE][/FONT][/COLOR]

2. Font

  
[FONT=Courier New][Browsable(false)][/FONT]
[FONT=Courier New]public string MyFontSerialize[/FONT]
[FONT=Courier New]{[/FONT]
[FONT=Courier New]get { return NinjaTrader.Gui.Design.[COLOR=blue][B]SerializableFont[/B][/COLOR].ToString(textFont); }[/FONT]
[FONT=Courier New]set { textFont = NinjaTrader.Gui.Design.SerializableFont.FromString(value); }[/FONT]
[FONT=Courier New]}[/FONT]
 
[FONT=Courier New][XmlIgnore()][/FONT]
[FONT=Courier New][Description("Font of Bar Numbers")][/FONT]
[FONT=Courier New][Gui.Design.DisplayName("Text Font")][/FONT]
[FONT=Courier New][Category("Parameters - Font")][/FONT]
[FONT=Courier New]     public System.Drawing.Font TextFont[/FONT]
[FONT=Courier New]     {[/FONT]
[FONT=Courier New]         get { return textFont; }[/FONT]
[FONT=Courier New]         set { textFont = value; }[/FONT]
[FONT=Courier New]     }[/FONT]

3. Pen
Not out of the box but you can roll your own, so it saves Color, DashStyle & width of pen.
As KBJ has posted an update for v7.0, I refer you to his post.

4. Filename
I wrote my own for this, unfortunately the code is too long for this post. I'll split it & do a separate post when I tidy it up.

5. Roll your own.
Ninja just nses standard .NET code & standard .NET properts pane. So you will find a ton of stuff on serialization on the MSDN.Microsoft.com site among others.

I hope this gets you started.

Serial

Thanks David - much appreciated. Turned out it was the pen that was causing my serialisation issue - if I declared it as a variable it messed up ; new instance within Plot override it was quite happy

[David Lean]

Interesting, I just created an indicator with 4 PEN parameters. I used the code exactly as is posted on the Ninja site, in the OnBarUpdate() event. It ran fine. So you shouldn't feel compelled ot use the Plot() method if that wasn't part of your original design.

(In fact I like it better than the serialization routines, I was using in v6.5, so I ditched my code & will use it from now on.)

Plot

I override Plot a lot in my indicator so this has been a sort of useful excursion. Thanks for the update.
