RE: Initiating a phone call (dialing) programmatically on the Tre o 600

[Jeffry Loucks]

Try using the dialer helper. First, check for the existence of the dialer
helper. Second, use the helper to place the call:

Boolean DialPhone(char *pPhoneNumber, char *pDisplayName)
        {
        if (VerifyHelper(kHelperServiceClassIDVoiceDial,0))
                return DialerHelper(pPhoneNumber,pDisplayName);
        return false;
        }

Boolean VerifyHelper(UInt32 serviceClassID, UInt32 helperAppID)
        {
        SysNotifyParamType notifyParam;
        HelperNotifyEventType helperEvent;
        HelperNotifyValidateType helperValidate;

        MemSet(&notifyParam,sizeof(notifyParam),0);
        notifyParam.broadcaster = <your_creator_id>;
        notifyParam.notifyType = sysNotifyHelperEvent;
        notifyParam.notifyDetailsP = &helperEvent;

        MemSet(&helperEvent,sizeof(helperEvent),0);
        helperEvent.version = kHelperNotifyCurrentVersion;
        helperEvent.actionCode = kHelperNotifyActionCodeValidate;
        helperEvent.data.validateP = &helperValidate;

        MemSet(&helperValidate,sizeof(helperValidate),0);
        helperValidate.serviceClassID = serviceClassID;
        helperValidate.helperAppID = helperAppID;

        SysNotifyBroadcast(&notifyParam);
        return notifyParam.handled;
        }


Boolean DialerHelper(char *pPhoneNumber, char *pDisplayName)
        {
        SysNotifyParamType notifyParam;
        HelperNotifyEventType helperEvent;
        HelperNotifyExecuteType helperExecute;

        MemSet(&notifyParam,sizeof(notifyParam),0);
        notifyParam.notifyType = sysNotifyHelperEvent;
        notifyParam.broadcaster = <your_creator_id>;
        notifyParam.notifyDetailsP = &helperEvent;

        MemSet(&helperEvent,sizeof(helperEvent),0);
        helperEvent.version = kHelperNotifyCurrentVersion;
        helperEvent.actionCode = kHelperNotifyActionCodeExecute;
        helperEvent.data.executeP = &helperExecute;

        MemSet(&helperExecute,sizeof(helperExecute),0);
        helperExecute.serviceClassID = kHelperServiceClassIDVoiceDial;
        helperExecute.dataP = pPhoneNumber;
        helperExecute.displayedName = pDisplayName;

        SysNotifyBroadcast(&notifyParam);
        return notifyParam.handled;
        }

Subject: Initiating a phone call (dialing) programmatically on the Treo 600


Hi,

I need to dial a number on the Treo 600, and it doesn't seem to be working.
It causes a crash, and according to the system log, the application causing
the crash was "Phone", and not my own application.

Anyway, here's the code I'm using to initiate the call:

Wait -- one more thing: everything works, if I set confirm to true, or copy
the values for name and number from string constants.
