XML Serialization revisited

[zweistein]

Hi snaphook,

for simplicity you have 2 function:

Serialize(int T1target){}

and int T1Target=Deserialize(){}

Serialize writes the parameter to some file and Deserialize() reads it back in. For simplicity here the variable is a single int. In reality you would serialize your whole strategy class MyStrategy : Strategy
By setting the [XmlIgnore] attribute you define which parameters to save.

You should find examples on XmlSerialize functions either in the forum or on MSDN site or some other C# site.


Ok.

Once you have the Serialize and Deserialize which dipend on your parameters


then put

Dispose(){
Serialize()
... other stuff
base.Dispose();
}

in your class to automatically save the parameters

you do then:

[Description("Target 1in ticks")]
[Gui.Design.DisplayName("\tT1 Target")]
[Category("Parameters")]
public int T1_Target
{
get { return t1; }
set {
value=Deserialize(); // instead from GUI you read in value from your file
// this should work as the get function is called later from the GUI
//(to show in the properties box)
t1 = Math.Max(1, value);
}
}


be careful with Deserialize,as it might be called when Initialize() is not yet called, so you are restricted concerning access to class variables. check the log etc

I am just so thick and I apologize for that. Do you mind holding my hand just a bit longer?

My Serialize function:
protected void SerializeSettings()
{
Print("Saving Current Settings");//Note to output window
DWM_AutoTrader dwmat = new DWM_AutoTrader();
dwmat.TypeEntry = typeEntry;
dwmat.T1_Target = t1;
dwmat.T2_Target = t2;
dwmat.T3_Target = t3;
.
.
.
}

My Deserialize function:
protected void DeserializeSettings()
{
Print("Retrieving Settings");//Note to output window
DWM_AutoTrader dwmat = new DWM_AutoTrader();
XmlSerializer mySerializer = new xmlSerializer(typeof(DWM_AutoTrader));
using (FileStream fs = File.OpenRead(@filePath))
{
dwmat = (DWM_AutoTrader)mySerializer.Deserialize(fs);

typeEntry = dwmat.TypeEntry;
t1 = dwmat.T1_Target;
t2 = dwmat.T2_Target;
t3 = dwmat.T3_Target;
.
.
.
}

This works great but you must attach the strategy and click OK for DeserializeSettings() to retrieve the saved settings. If I set the t1 properties to that below, I get an error because the DeserializeSettings() function returns void.

Properties for t1:
[Description("Target 1. Set to 0 for no target.")]
[Gui.Design.DisplayName("\tT1 Target")]
[Category("Parameters")]
public int T1_Target
{
get { return t1; }
set { value=DeserializeSettings();
t1 = Math.Max(0, value); }
}

Thanks,
