Creating the GPRS Internet Access Point (IAP) OS version independent

In order to create the IAP, CCommsDatabase is used. The following code example creates all the table entries manually. It actually duplicates the emulator's "Winsock" IAP initial settings. CreateNewIAP() is the main function.

#include <commdbconnpref.h>
#include <commdb.h>
#include <cdbpreftable.h>

view->WriteTextL(TPtrC(COMMDB_NAME), KWapApName);

Need to link with commdb.lib in the .mmp file.

 LIBRARY commdb.lib

The code requires WriteDeviceData capability to run on devices based on Symbian OS v9. So add them in mmp .file.

Capability  WriteDeviceData
