Make call with CTelephony

[honour88]

Hi, All.

I have a problem with Ctelephony. When I try this code, I have a error.How can I fix it?

.h file ;
private:
MCallDialerCallBack& iCallBack;

.cpp file ;
CMyCallDialer *imycaller;
imycaller = CMyCallDialer::NewL(iCallBackk);

Error;

1254828344386 '&' reference member 'iCallBackk' is not initialized

thank you all.

you need to derive your AO class from the MCallDialerCallBack, and implement the functions defined in the interface, and then use the this-pointer when giving the reference to the CMyCallDialer class.

Sorry I didn't understand. I'm newbie on c++. Can you give me an example?
My MCallDialerCallBack class;

class MCallDialerCallBack
{
public:
virtual void DialerDone(TInt aError)=0;
};

in you Cpp file, you have some class I suppose, in which you have the CMyCallDialer *imycaller; as a member. Then just derive the class from MCallDialerCallBack, and implement the DialerDone() function in it, then you can use the this-pointer inside the class, in the place where the MCallDialerCallBack would be used.

MCallDialerCallBack& iCallBack;

this "iCallBack" is just a reference, which is needed to initialize(creat an object of it/set to the pointer of an object), before using it.
