How to get a variable from my settings.js file in to my gadget.js file

Question

I am trying to develop a database driven Windows 7 Gadget and the settings page has multiple filters. I have captured the selected values in the drop down(select) and trying to pass these values to the query in the Gadget.js file upon clicking the OK button in the settings page.
i have tried using

System.Gadget.Settings.Writestring("SN", SNValue); in the settings.js file and

var S = System.Gadget.Settings.readString("SN"); in the gadget.js file.

basically i would like to use the "SN" in Gadget.js file.

please let me know where i am going wrong..

Thanks in advance.

I don't know if this is just a mistake in your question, but you have a problem with your use of the writeString method:

System.Gadget.Settings.Writestring("SN", SNValue); // there is no Writestring method
System.Gadget.Settings.writeString("SN", SNValue); // this is correct

If that doesn't help then without seeing more code I can only really offer you the following advice:

• Don't confuse System.Gadget.onSettingsClosing with System.Gadget.onSettingsClosed.  System.Gadget.onSettingsClosing would be used in settings.js to write the "SN" setting and System.Gadget.onSettingsClosed would be used in gadget.js to read the "SN" setting.  I ran into this when I first started out in gadget development.
• As well as writing the setting, you could call the function you want to use directly from the settings.js using System.Gadget.document.parentWindow.functionName(SNValue).

I hope that helps.

Hi Andy,

Thanks for your quick response. As you pointed, i had used Writestring method instead of writeString and it was my mistake. But even then after correcting it i am not able to pass the value from the settings page to gadget upon clicking the OK button. I will try to post the sample code later by EOD to clearly illustrate what i am doing.
As you said, i was also initially confused about  the System.Gadget.onSettingsClosing with System.Gadget.onSettingsClosed but later read about them and used accordingly.

Before that, can you please clarify me what does "name of the settings key" mean...

Syntax

System.Gadget.Settings.writeString(strName, strValue)

Parameters

strName	Required. String that specifies the name of the Settings key.
strValue	Required. The String value to store.

Thanks for your clear explanation.
