fixed width fonts
I am using a lot of lists where each line in the list contains a number of fields eg. product quantity price. However Constructor does not seem to have any fixed width fonts making it very difficult to format the lines so that a particular field in each line always starts and ends at the same point. Is there any way around this? Should I be using lists in the first place?

Launching HotSync programmatically
Hi all,
I am wondering whether it is possible to launch HotSync programmatically
from an application I am developing. Ideally I would like to launch HotSync
as a subroutine so that it returns to the same point in my application once
it is finished. I haven't been able to find any code to do this specifically
and my own attempt (shown below) causes a crash. When debugging it seems to
get as far as the StartApplication funcion (I am assuming this is HotSync's
StartApplication function) and then crashes with an "invalid opcode"
message.I'm not even sure if this is possible and I am probably making some
very obvious mistakes but if anyone knows how to do this and can show me a
piece of code I would be very grateful.
Regards,
Ger

Launching application directly after reset
Hello everyone, My problem is very similar to Marta's. I would like to launch my application directly after a (soft) reset so that no key has to be pressed. Since SysUIAppLaunch cannot be used as a response to a SysAppLaunchCmdSystemReset launch code I have tried sending my application a launch code after a reset that then causes a normal launch code to be sent to the app. case sysAppLaunchCmdSystemReset: error=SysBroadcastActionCode(55000, NULL); break; case 55000: error=SysCurAppDatabase(&cardNo, &dbID); if (!error) error=SysUIAppSwitch(cardNo, dbID,sysAppLaunchCmdNormalLaunch, 0); break; However the system still stalls at the Preference Panel. I have heard that Handscape have an application that will allow you to launch you app directly (I think its called vFlashPro) but I'm not sure. Has anyone tried to do this or has anyone used this product?

Switching backup bit for a database
Hello everyone, This is a simple problem. I have a checkbox that when ticked causes the backup bit for a database to be set and when unticked causes the backup bit to be unset.

Pop-up lists close when alarm is triggered
Hello everyone,
Here is just something I noticed. If you call another application within
your application and then set an alarm, any pop-up lists in the called
application will close when the alarm is triggered. This is really
problematic when the alarm is called continuously until some criterion is
met.
For example I call HotSync from my application and then set and alarm:
err = DmGetNextDatabaseByTypeCreator (true, &searchState,
sysFileTApplication, sysFileCSync,true, &cardNo, &dbID);
if (!err)
{
thisAppErr=SysCurAppDatabase(&thisAppCardNo, &thisAppLocalID);
err=SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmdNormalLaunch, 0);
if (!err)
{
if (!thisAppErr) thisAppErr = AlmSetAlarm (thisAppCardNo, thisAppLocalID,
cmdAlarmAfterHotSyncConfig, TimGetSeconds(), true);
}
}
When handled in the PilotMain function this alarm when triggered looks at
the GNextUIAppDBID system marcro to determine if HotSync is still the
running application. If it is then the alarm is set again, if not the
SysUISwitch is used to relaunch my application. In this way my application
relaunches as soon as any other application is opened.
case cmdAlarmAfterHotSyncConfig:
error = DmGetNextDatabaseByTypeCreator (true,
&searchState,'appl', 'MTyp', true, &cardNo, &dbID);
HotSyncCardNo=0;
HotSyncDBID=DmFindDatabase(HotSyncCardNo, "HotSync");
if(HotSyncDBID!=0)
{
// If HotSync is not the running application
relaunchApp=(GNextUIAppDBID!=HotSyncDBID);
}
if(relaunchApp==true)
{
if (!error) error=SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmdNormalLaunch,
0);
}
else if (!error) error = AlmSetAlarm(cardNo, dbID,
cmdAlarmAfterHotSyncConfig, TimGetSeconds(), true);
break;
The problem is that each time the alarm is triggered (i.e. when HotSync is
still the current application), any popped up list closes, meaning that they
only stay open for a fraction of a second and are inaccessible. Am I missing
something here?

Ger

Finding the current remote HotSync configuration
Hello everyone,
My application launches HotSync programmatically after asking the user to
choose between a remote or direct serial connection.
if (commsMode==REMOTE_COMMS)
{
err=SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmdSyncRequestRemote, 0);
}
else if (commsMode==LOCAL_COMMS)
{
err=SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmdSyncRequestLocal, 0);
}
There are to be two remote connection configurations on the handheld, one
using a landline modem, the other an internal GSM modem.
The problem is that my application needs to know which remote configuration
is the current HotSync remote configuration before it launches HotSync(i.e.
whether it is GSM or landline). This is a very basic question but is there a
means of interrogating a HotSync database (or any other database) in order
to find out which of the available configurations is set as the current
remote HotSync configuration.
An even better solution would be to be able to select the current remote
configuration from within the application but I don't know if this is
possible.
Regards,
Ger

Calling a Windows RAS connection programmatically
Hello everyone, On the "Network Preferences" panel you can configure a "Windows RAS" type connection and specify a particular connection method and phone number etc. You can then press the connect button to make the connection to the host. Once this RAS connection has been configured is it possible to call it programmatically outside the Network preferences panel, from your own application? I know that in a Windows and Windows CE type environment you can enumerate the RAS connections within your app and call a particular connection by passing its name as a parameter. Can the same be done in Palm?

Retain user details after hard reset.
I know this is a long shot but is there anyway to force a Palm unit to retain its user details when the battery goes flat or after a hard reset. Is there a database that can be flashed that will allow the unit to retain the userID etc. The reason I am asking is that we are doing a network HotSync over land-line and GSM modem but as far as I know the Network HotSync requires the user to be set up on the PC beforehand. Therefore in the event of a battery going flat (and therefore the data RAM being cleared)the unit will have to be returned to base in order to set it up again.

bus error in Emulator when adding Connection profile
Can anyone tell me why the following code would cause a bus error in POSE
when the added connection is viewed in the Connection Preferences Panel. The
AddMyProfile function is taken directly from the documentation on
CncAddProfile in the kb.
// found in documentation for CncAddProfile
void AddMyProfile()
{
CharPtr myConNameP;
Err err;
myConNameP = (CharPtr)MemPtrNew(cncProfileNameSize);
StrCopy(myConNameP, "Foobar");
err = CncAddProfile(myConNameP, 'u328', 57600,
0, 0, "AT&FX4", 0, true, false);
MemPtrFree(myConNameP);
}
// and later use AddMyProfile to add connection
case ctlSelectEvent:
if (eventP->data.ctlSelect.controlID == MainAddConnectionButton)
{
AddMyProfile();
Handled=true;
}
break;
The new connection seems to be successfully added on the device but the bus
error occurs in POSE. To be more specific the bus error occurs when the
Details
button is tapped (i.e. the connection details form displaying the
speed and flow control cannot be viewed).

Re: Pls Help! - to to prevent accidental deletion of Palm Application?
Palm applications such as Calc, Memopad etc are installed on the ROM and therefore can only be deleted by reconfiguring the ROM and downloading it to the unit. Why don't you install your application in flash memory using something like FlashPro by Handera. That way your application won't show up on the deletion list. It won't disappear after a hard reset or flat battery either.

Re: Handling the contrast button on Palm V and Palm IIIx
What about doing something like the following? In your application, re-map
the contrast button so that it launches some application (e.g. Calc) using
PrefSetPreference.
Create a global variable that delermines whether or not you allow an exit
from your application:
Boolean bAllowAppExit;
Then whenever you show an alert or calender etc make sure that the variable
is set to false. In your event loop, stipulate that this variable must be
set to true to allow an AppStop event:
do
{
EvtGetEvent( &event, 2000 );
// more code
}while(event.eType != appStopEvent || bAllowAppExit==false);
I know its convoluted but it should work. I used it to prevent a user from
exiting my application during a FrmCustomAlert type situation.

Re: newbie question: how to read a string from a MemHandle?
I'm not sure what you are doing wrong. As I see it to write the data to the
handle you should be doing something like the following:
// global MemHandle
MemHandle h = NULL;
// Append data to whatever is already in handle
void WriteDataToHandle(Char *dataInP)
{
Char *strP;
Err err;
UInt16 len = StrLen(dataInP);
if (!h)
{
h = MemHandleNew(len+1);
if (h)
{
strP = (Char *)MemHandleLock(h);
if (strP)
{
StrCopy(strP, dataInP);
MemHandleUnlock(h);
}
}
}
else
{
err = MemHandleResize(MemHandleSize(h)+(len+1));
if (!err)
{
strP = (Char *)MemHandleLock(h);
if (strP)
{
// Append data
StrCat(strP, dataInP);
MemHandleUnlock(h);
}
}
}
}
// Read data from handle
void ReadDataFromHandle()
{
Char *strP = NULL;
if (h)
{
strP = (Char *)MemHandleLock(h);
if (strP)
{
DisplayStr(strP);
MemHandleUnlock(h);
}
}
}
// Finally free handle
MemHandleFree(h);

Ger

at first thanx for your reply. However, when i try to access strP my
programm crashes telling me it read memory from the memory manager data
structures. Any idea what i did wrong? i locked the handle to write it,
unlocked it, locked it again by
strP = (Char *)MemHandleLock(h);
accessed strP and it crashed.

Saving Bitmap as resource programmatically
I am creating a test bitmap (160x120 16 bit depth, BitmapV2) and trying to
save it as a bitmapRsc resource in a database. I create the bitmap,
associate it with a created offscreen window, draw some simple lines. After
its created BmpGetSizes results in the expected header size of 24 bytes and
data size of (160x120x2) 38400 bytes.
I thought I could write the bitmap to a resource record using the following
code:
h = DmNewResource(gImageDbP, bitmapRsc, resId, headerSize+dataSize);
if (h)
{
recP = MemHandleLock(h);
if (recP)
{
// bmpP = BitmapPtr created by BitmapCreate(160, 120, 16, NULL,
&error);
DmWrite(recP, 0, bmpP, headerSize);
DmWrite(recP, headerSize, BmpGetBits(bmpP),dataSize);
MemHandleUnlock(h);
}
DmReleaseResource(h);
}
However the resource doesnt display as expected and when BmpGetSizes is
called on the resource bitmap it results in a header size of 16 bytes.
Anyone know where I've messed up?
Incidentally the aim of all this is to allow the HotSync of such a bitmap
resource (created using Veo camera on Tungsten) to a bmp file on the host.
So far I am getting really weird results with certain colours (the lighter
ones) displaying perfectly but with darker colours coming out as green etc.
Does anyone know where I could find code to translate the bitmap properly?
Regards,
Ger

Re: CheckBox in List.
I had exactly this requirement for a project but I approached it differently. I wrote two functions, the first to draw an unchecked checkbox and the second to draw a checked checkbox (functions used WinDrawLine). Each of the records to be displayed on the list began with a Boolean value to indicate whether or not the checkbox should be checked. Then in the list draw callback function (set using LstSetDrawFunction) the list item would be drawn checked or unchecked according to the value of the Boolean. When the user selected an item on the list the value in the associated record would change and the list would be redrawn. That was my approach and it worked well but if you do manage to find the values for drawing them as symbols it might be better.

Re: NetLibOpen returns netErrPPPTimeout
Your device is not able to establish a network connection for some reason. The reason the emulator works without a problem is that it is using the hosts tcp/ip stack and therefore is already on a network (most likely). Therefore NetLibOpen will succeed automatically. Are you sure you have set up the configuration on the Network Preferences panel on the device properly? How is your device connecting to the network?

Re: NetLibOpen returns netErrPPPTimeout
You can't establish a PPP connection via serial cable automatically. The PC must be set up to accept an incoming connection via the serial port. If you are running Windows 2000 or NT then take a look at the following link http://www.users.globalnet.co.uk/~echobase/network/win2k/#linkdirect It will show you how to set up both the PC and the Palm unit. Alternatively you could download Mocha PPP (http://www.mochasoft.dk/f_view.html) and use that.

Re: Help with sockets! plz!
The problem may be that the unit is running out of resources because the created sockets are 'lingering' after they are shutdown. I had the very same issue before that the ftp client could not create or connect sockets after a certain number of data connections had been made. The following code is from memory so you may want to check it but it should cause the resources for a socket to be freed immediately upon shutdown. Call the code after the socket has been created: NetSocketLingerType linger; Int16 retVal; linger.onOff = false; linger.time = 0; // shouldn't be necessary retVal = NetLibSocketOptionSet(libRefnum, theSocket, Socket, // Option level SockLinger, &linger, sizeof(NetSocketLingerType), myNetTimeout, &err); Lookup NetLibSocketOptionSet in the PalmOS reference for a description of the parameters.
