you can use low level function of MCI.

low level :
waveInOpen etc.

or send mci command string such as
wsprintf(lpstrCommand, "record %s %s %s", lpszDeviceID, lpszRecordFlags,
    lpszFlags);
and then call
MCIERROR mciSendCommand(  MCIDEVICEID IDDevice,    UINT uMsg,            
  DWORD fdwCommand,        DWORD dwParam          );

record through mciWnd is a easy way.
you can create a record window as a child
HWND MCIWndCreate(  HWND hwndParent,        HINSTANCE hInstance,  
  DWORD dwStyle,          LPSTR szFile          );

Now I can Record the sound either through Mic or Line In ,but the problem is that I don't have the control over selection of Mic or Line In.I have to run JukeBox player to assign recording source as Mic or Line In. I wan't to implement it in my application. Is there any ,which can do that...

Yes, you can control it by using Audio Mixers functions. It is a little tough. Take a look at some articles about Audio Mixers at CodeGuru.

Also, check out the Platform SDK sample MixApp.
