simple RConnection question

[rtrnokia]

Maybe this is a more general question about R* classes but here goes.

When I start my application upon user input I establish a connection to an access point. e.g.

class MyClass
{
private:
   /* other members */
   RSocketServ iSocketServer;
   RConnection iConnection;
};

MyClass:StartMyAppL()
{
   User::LeaveIfError(iSocketServer.Connect());
   User::LeaveIfError(iConnection.Open(iSocketServer));
   /* other stuff */
}

Later in another part of the program I need to do a hostname lookup (among other things). This is done in another class where I do not have access to the RConnection in MyClass. (keeping in mind I have not disconnected the earlier connection to the AP)

class OtherClass
{
private:
    RSocketServ iSocketServer;
    RConnection iConnection;
    RHostResolver iResolver;
};

void
OtherClass::LookupL()
{
    User::LeaveIfError(iSocketServer.Connect());
    User::LeaveIfError(iConnection.Open(iSocketServer));
    User::LeaveIfErorr(iResolver.Open(iSocketServer, KAfInet, KProtocolInetTcp, iConnection));
}

When LookupL() is executed the third statement leaves because iResolver.Open returns -18 KErrNotReady. Is this like "Device already in use"?

Do I have to make available my original RConnection to the LookupL() function and use it instead of opening another? If I choose not to provide the iConnection to the iResolver.Open() call the code works fine but I am prompted for access point selection again (which I don't want). So what am I doing wrong? What is the correct way to use RConnection?

Thanks

hi rtrnokia,

In your class u tried to open a resource which is holded by another class , so its returning the object doesn't not ready to use that resource that means the resource already used by your previous class.Still its holding that resource.

No need to implement 2 classes, you can use the one class to make the connection. you can start multiple connections using RConnection.Start() method.

Use these codes to hide the access point prompt,
//Define preferences for connection
TCommDbConnPref prefs;
prefs.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
TUint32 iIapId; //Get the proper APN from the CommDb.
prefs.SetIapId(iIapId);


Cheers,

Ahh, I see I thought I would just get another handle to the already open IAP. I also notice I did not show the Start() call I was making in my original post.

So to get what I expect it will really be necessary to pass the existing RConnection which was already Start()ed for use by my second class.

Thanks I'll give it a try.
