How to select a number from the address book..

[Rob]

I couldn't believe this was so hard to figure out.

PhoneNumberLookupCustom and PhoneNumberLookup are both pretty useless for  
letting users select a number from the address book on the Treo 600 and  
Treo 650 (do they work better in other devices?)

The function below returns a handle to a number which the user has  
selected.
It works on the t600 and the t650 at least.

Thanks to the posts on this group for getting me there.

Enjoy!

//returns Handle to phone number string if one is selected
//returns NULL if no number selected
//caller is responsible for freeing handle.

MemHandle       SelectPhoneNumber(void)
{
DmSearchStateType stateInfo;
UInt16 cardNo;
LocalID dbID;
UInt32 result;
Err err;
UInt32 dbCreator = 'PAdd';

SysNotifyParamType params;
AddrLookupParamsType lookupParams;
Char    lookupString[]="";
Char     *textP = "Select Number",*addP = "Ok";

MemSet(&params, sizeof(params), 0);
MemSet(&lookupParams, sizeof(lookupParams), 0);

params.notifyType =addrAppNotificationHsLookup;//  
addrAppNotificationCmdCallerID;
params.notifyDetailsP = &lookupParams;

lookupParams.pasteButtonText = addP;
lookupParams.title = textP;
lookupParams.field1 = addrLookupSortField;
lookupParams.field2 = addrLookupVoicePhones;
lookupParams.field2Optional = true;
lookupParams.userShouldInteract = true;
lookupParams.formatStringP = "^voicephone";

err = DmGetNextDatabaseByTypeCreator(true, &stateInfo,  
sysFileTApplication,dbCreator, true, &cardNo, &dbID);
if (err)
        {
        dbCreator = 'addr';
        err = DmGetNextDatabaseByTypeCreator(true, &stateInfo,
        sysFileTApplication, dbCreator, true, &cardNo, &dbID);
        }

ErrNonFatalDisplayIf(!dbID, "Could not find app");
if (dbID)
        {
	err = SysAppLaunch(cardNo, dbID, 0,  
sysAppLaunchCmdNotify,(MemPtr)&params, &result);
        ErrNonFatalDisplayIf(err, "Could not launch app");
        }
        
return lookupParams.resultStringH;
