i use this function to dial number on treo 650
static Boolean cccDialNumber(char *number, char *extra, Boolean autoExtra)
{
PhoneAppLaunchCmdExtendedDialType *phonedial;
PhoneAppLaunchCmdDialType *phonedialsimple;
Err err;
UInt32 creator;
UInt16 card;
LocalID id;
DmSearchStateType sstate;
Boolean ok;
ok=false;
//we must find phone application
creator=hsFileCPhone2;
err=DmGetNextDatabaseByTypeCreator(true,&sstate,'appl',hsFileCPhone2,true,&card,&id);
if(err==dmErrCantFind)
{
//v2 version not found so lets look for v1
creator=hsFileCPhone;
err=DmGetNextDatabaseByTypeCreator(true,&sstate,'appl',hsFileCPhone,true,&card,&id);
}
if(!err)
{
//we will launch application with special launch code
//so we must prepare data for this launchcode
if(extra && extra[0])
{
phonedial=(PhoneAppLaunchCmdExtendedDialType
*)MemPtrNew(sizeof(PhoneAppLaunchCmdExtendedDialType));
if(phonedial)
{
MemSet(phonedial,sizeof(PhoneAppLaunchCmdExtendedDialType),0);
phonedial->version=1;
phonedial->confirm=false;
phonedial->number=(char *)MemPtrNew(StrLen(number)+1);
StrCopy(phonedial->number,number);
MemPtrSetOwner(phonedial->number,0);
phonedial->extraDigits=(char
*)MemPtrNew(StrLen(extra)+1);
StrCopy(phonedial->extraDigits,extra);
MemPtrSetOwner(phonedial->extraDigits,0);
phonedial->autoExtraDigits=autoExtra;
MemPtrSetOwner(phonedial,0);
//everything is ready, so actually its time to call
phone and finish it
err=SysUIAppSwitch(card,id,phoneAppLaunchCmdExtendedDial,phonedial);
if(!err)
ok=true;
}
}
else
{
phonedialsimple=(PhoneAppLaunchCmdDialType
*)MemPtrNew(sizeof(PhoneAppLaunchCmdDialType));
if(phonedialsimple)
{
MemSet(phonedialsimple,sizeof(PhoneAppLaunchCmdDialType),0);
phonedialsimple->version=1;
phonedialsimple->confirm=false;
phonedialsimple->number=(char *)MemPtrNew(StrLen(number)+1);
StrCopy(phonedialsimple->number,number);
MemPtrSetOwner(phonedialsimple->number,0);
MemPtrSetOwner(phonedialsimple,0);
//everything is ready, so actually its time to call phone and
finish it
err=SysUIAppSwitch(card,id,phoneAppLaunchCmdDial,phonedialsimple);
if(!err)
ok=true;
}
}
}
return(ok);
}
if no extra digits are set dialing uses phoneAppLaunchCmdDial and it works
if extra digits are set it should use phoneAppLaunchCmdExtendedDial.
sysuiappswitch is succesfull but instead of dialing number it immediately
returns to my application
in header file there is note to phoneAppLaunchCmdExtendedDial that
/** Extension to phoneAppLaunchCmdDial. It has autoExtra digits field
This is ARM only launch code, meaning if you are calling from a 68k code
needs to deal with endianess and byte swapping*/
so i started to experiment with byteswapping
- if i byteswap all pointers including pointer to structure i get crash
memorymgr.c, Line:3844, ptr is handle
- if i byteswap only pointers inside of structure then it behaves the same, it
returns immediately to my application
- if i byteswap everything - pointers inside, adress of structure and launchcode
then my application closes and treo resets. simulator crashes without any
message, only windows say that it happened in emul68k.dll. in fact it seems that
this result i get everytime when launchcode is byteswapped and rest doesn't
matter
so i think i run out of possibilities. any idea what may go wrong? i am
developing application for someone whoe really wants this feature :-(
memorymgr.c, Line:3844, ptr is handle
