c# - Can I modify a custom configuration section using ConfigurationManager? -


i have app.config of form

<?xml version="1.0" encoding="utf-8"?> <configuration>     <configsections>         <section name="custom.config" type="system.configuration.dictionarysectionhandler, system, version=1.0.3300.0, culture=neutral, publickeytoken=b77a5c561934e089" />     </configsections>      <kcura.config configsource="custom.config" /> </configuration>

with custom configuration file custom.config of form

<?xml version="1.0" encoding="utf-8"?> <custom.config>     <add key="foo" value="bar" /> </custom.config>

i've inherited code, , there no existing configurationsection or configurationsectionhandler associated custom.config section.

i can access value of foo fine 

 directcast(system.configuration.configurationmanager.getsection("custom.config"), system.collections.idictionary)

but update value, programatically (for testing purposes). is possible?

i've read following, , i'm still stumped; seem imply namespace reading values, not full crud:

you'll have modify custom.config file on disk using xdocument you'll need call refreshsection on configurationmanager

this refresh named section next time retrieved re-read disk.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
