How can I call shared libraries at runtime?

I can Find a Shared Library. I can Open a Shared Library. I know which custom function number I want to call. I know how many arguments the function takes from .inf files. I have a fairly decent idea as to what types of arguments I have. I have a fairly decent idea as to what return type I will see. This is what I need to know. Without using header files that compile in function prototypes for every library, how can I call these functions? Will I have to manually push my args on to the stack, and somehow call the relevant trap? Does anyone have any other related suggestions?

Re: multi-threaded application in Palm OS 5.2
Hello Roger, I appreciate your help and others as well. I understand your points and they are helpful. But what I want to do it to port some Windows Mobile applications, which use true multi-task (multi-thread more accurately). The differences of multi-task senses between my application and the solution you mentioned are, 1. Not a hacking way by using un-documented features; 2. Callback function is not working in all cases of a true multi-threaded (for example, an elegant producer -- consumer case, backtest sample in financial stock exchange simulation -- one thread to simulate one user to make stock deal, other types of games ...). Because callback function works on per notification basis, but multi-task application concept is beyond that. What I concern is the *true* multi-task environment, which supports generally all kinds of multi-threaded application (for example, the two samples I listed above).

Re(2): trouble with serial communcation -- SrmSetWakeupHandler
There's an interesting item that was in the PalmSource KB, Answer 413 (I
can't verify if it is still there right now - the developer pavilion
appears to be down):
The Palm Application Compatibility Environment (PACE) is not interrupt
safe so 68K applications running through PACE may experience problems if
they attempt to run during an interrupt. A couple of ramifications of
this are:
SysNotifyBroadcastFromInterrupt is non existent through PACE in Palm OS
5. Developers should check the OS version before they attempt to make
this call.
Serial Wakeup Handlers set with SrmSetWakeupHandler may work
inconsistently under different versions of OS 5 and will not work at all
via the Palm OS 5 Simulator. In general, developers should avoid using
serial wakeup handlers in OS 5.
**If you do attempt to use wakeup handlers in an OS 5.0 environment note
that they will only work while the application that set the wakeup
handler is still active. This is fixed in OS 5.2, but the wakeup handler
itself should be stored in a memory location separate from the
application (such as copying the function into a FtrPtr and setting the
wakeup handler to this FtrPtr).
example:
//The size of the handler function can be calculated by subtracting the
memory location
//of the handler function from the next function in your code resource.
sizeOfPatch = (UInt32)((UInt32)FunctionAfterHandler- (UInt32)
HandlerFunction);
//allocate a FtrPtr the size of our handler and then copy it in.
FtrPtrNew(appFileCreator, ourFuncFeature, sizeOfPatch, funcP);
if (funcP)
{
//copy callback function to the above address.
DmWrite(funcP, 0, (MemPtr)HandlerFunction, sizeOfPatch);

Re: code obfuscator for Palm?
It depends on the development tool you use. You're fine if you use CodeWarrior, PRC Tools or NS Basic. These all compile the code in such a way that you'd have to have a lot of inside knowledge to reverse compile. I do not know about other tools. For Pocket PC, Visual Studio .NET produces code in CLR which does need to be obfuscated; eMbedded Visual Basic does not even have an obfuscator. If you use tools such as eMbedded Visual C++ or NS Basic, you're OK. Anyone know of a utility or tool that does this? Is it even needed? I don't know if it's possible or common to de-compile a .prc into code. I am considering showing an app to a larger developer/publisher, and am worried about sending them a demo and how to protect my IP. I've developed the app on PocketPC as well and Visual Studio has a Obfuscator built in (which doesn't work anyway), so it got me wondering about the Palm side. __ Discover Yahoo!

Re: Off-topic: PalmOS or WinCE
Hi All... Just new to the PDA programming and looking to add PDA integration to some of our products, so I have a few questions that I was hoping to get real developer feedback from: 1. I seem to like the PalmOS tools much better than the WinCE.Net stuff Any comments comparing both the developement and the user aspects would be greatly appreciated. 2. I have looked as CASLSoft for developing... Any comments or alternates? Probably the first of many questions, so thank you all in advance, I'll stay away from the religious wars. One way or the other, most applications can be done on either platform with reasonable success. One thing to look out for: think of the future, not just current devices. Both Windows CE and Palm OS will be making major changes to their architectures in the coming year or two. If you choose your dev tools carefully, they will insulate you from a lot of the hassles that will be caused. We've been doing a lot of work on this here. User's applications written in NS Basic will be able to run without change in Cobalt, Windows CE 5.0 or whatever finally comes out. There are well known and widely used dev tools (among them eMbedded Visual Basic and CodeWarrior) that will not make the jump.

hanging (needing a soft reset) after receiving characters from raw IR

Here is what the code looks like:
// prime the wake up handler
err=SerSetWakeupHandler(serRef, serialWakeupHandler, (UInt32) gSerialState);
err=SerPrimeWakeupHandler(serRef, 1);
// The wakeup handler. As far as I can tell, this never gets called: the
crash happens first.

Re(2): Palm Powered logo certification
My application is developed in Satellite Forms v5.2, but I would like to try to get the Palm Powered logo certification. According to the certification requirements, all debug options must be turned ON during emulator/simulator testing of our app. However, Satellite Forms requires that all debug options be turned OFF in order to run in the emulator (because of OS calls, I guess) without crashing. So... can a Satellite Forms-developed app be certified under this program?? Has anyone done this? Do you need a special exemption?? I would hope that you can't get an exemption. If Satellite Forms is not stable enough to be run with all the debug options, then it and anything created with it, should not qualify for the certification. The certification has been designed, as far as I understand it, to say that the applications run reasonably well and don't suffer from crashing issues. I'd recommend trying to get Satellite Forms to fix their application so that it can pass certification or write your application from scratch so that you don't rely on someone's unstable application. (I've never used Satellite Forms, but I'd be very afraid of any application that can't run in the emulator with all debug flags turned on.) It is not that simple. The philosophy of RAD tools is to keep the programmer away from low level details, such as memory allocation, or packing strings into database records, or dealing with subtle differences between OS versions, and so on. This is usually done through a runtime library, which behaves as a layer that translates what the programmer wants into low level Palm OS calls, and/or that provides helper functions. The problem is that it is almost impossible to write an efficient runtime library for Palm OS without either calling system use only functions (such as MemChunkNew) or either poking internal OS structures on 68k devices (fortunately, OS 5 provides enough functions to make this unecessary on ARM devices). Both triggers warnings when running with all options on. Another problem is that the emulator/simulator tends to be very suspicious. For example, a RAD tool may provide some sort of exception mechanism. To implement this, you have to write assembler code that crawls the stack up until it finds a handler for the exception. Unfortunately, reading and writing values from a stack frame which is not the officially active stack frame sometimes triggers an illegal memory access if all options are turned on. And there are many other examples. IMHO, the palm powered logo should take the development tool into account, or it will dramatically restrict the number of applications that can pass this certification... As far as I know, *all* RAD tools raise errors on POSE, and I don't think such tools are that bad... Pascal I can't agree. Originally, NS Basic had the same problem. We worked at it a bit and cleaned it up. In most cases it was simply sloppy programming. An NS Basic program should now be able to pass certification. A side benefit is that we can now use these messages as a debugging tool during our own development. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

MemPtrNew / MemPtrFree
Hello,
Since I'm a Palm OS newbie, I need some help. I'm debugging an applicaiton
using the Emulator and found out that the application sometimes gets memory
leaks error.
Ben Combee also suggested that I should use MemPtrNew to decrease my stack
size in my previous thread.
So, I've decided I should take a serious look at using MemPtrNew and
MemPtrFree to make the application more efficient.
However, I don't know how to use them.
This is the existing code in my Pilot Main:
UInt32 PilotMain(UInt16 cmd, MemPtr cmdPBP, UInt16 launchFlags)
{
ContextType context;
UInt16 error;
context.hasGlobals = launchFlags sysAppLaunchFlagNewGlobals;
if (cmd == sysAppLaunchCmdNormalLaunch)
{ globalContext = context;
error = AppStart(context);
if (error) return error;
FrmGotoForm(ID_FORM_LIST);
EventLoop();
AppStop(context);
return 0;
}
else if (codes snipped...)
I use ContextType to store Global variables and it's huge. That's the
problem. I need to free up the resources when ContextType is not used. I
just don't quite understand how to use MemPtrNew to free the memory.
Thanks for your help in advance.

Code Warrior and Palm Emulator question (stack overflow??)
Hello all,
I'm using CodeWarrior (V 9.2) for my Palm developement. I also downloaded
the palmos33-en-v.zip for the emulator and the palmos33-en-v.rom file from
PalmOS. I set it to duplicate my PalmV device so I can test my program using
the emulator.
I then complied my program using Code Warrior. I sync the prc and pdb files
to the emulator for testing. It abended everytime when I did a global search
inside my application.
This is the error message from the Palm OS Emulator:
Testpgm has overflowed the stack: The functions currently using the stacks
are: PrvMisAlignedForwardInnerBitBlt(52),...
I then debugged the code and found out it's actually happening in this part
of my code (the Global search area):
void AppDoSearch(ContextType *ctxt, FindParamsPtr params) {
EntryType entry;
Int32 i;
UInt16 cat;
RectangleType r;
char catname[CAT_NAME_LENGTH];
(skipped some of the codes...)
if (FindDrawHeader(params, catname) == true) {
params-more = true;
ctxt-prefs.findPos = -1;
ctxt-prefs.findCategory = cat;
return; (skipped the rest of the codes)
It actually abended during the call to FindDrawHeader.
The funny thing is, this is the Global search function in my program and it
is being called no matter if the Global search is coming from within my
application or other Palm applications such as Address or Calculator or
whateverelse.
This piece of code works in the emulator if the Global search is initiated
from outside my application! But not if I did a Global search while I'm in
my application!
Even stranger, if I hotsync the code to my PalmV device (the real device),
my application works! The Global search function works no matter if I do
Global search within my application or in other Palm applications.
Very strange. Is this an emulator problem or Code Warrior problem. I did a
search on the Palm-dev-forum knowledge database and found out an article
about the option
#pragma stack_cleanup on I thought the newer version of Code Warrior
resolved the stack cleanup problem and I don't have to set this parameter
(as it would increase the program size and slow down the execution).
Any suggestions?

Different callers - different amount of stack is used. Perhaps your app is
the one, which demands more stack.
The simplest thing you can do is to put the breakpoint to the start of
AppDoSearch() and once the debugger breaks, count manually the stack used by
all your callers. I.e. count the total size of all local variables that are
in the call chain between AppDoSearch and PilotMain. It is not exactly
equal
to what the compiler does, but it is a good estimate.
Probably you'll find an explanation.

char catname[CAT_NAME_LENGTH];
(skipped some of the codes...)
if (FindDrawHeader(params, catname) == true) {
params-more = true;
ctxt-prefs.findPos = -1;
ctxt-prefs.findCategory = cat;
return; (skipped the rest of the codes)
It actually abended during the call to FindDrawHeader.
The funny thing is, this is the Global search function in my program and
it
is being called no matter if the Global search is coming from within my
application or other Palm applications such as Address or Calculator or
whateverelse.
This piece of code works in the emulator if the Global search is initiated
from outside my application! But not if I did a Global search while I'm in
my application!
Even stranger, if I hotsync the code to my PalmV device (the real device),
my application works! The Global search function works no matter if I do
Global search within my application or in other Palm applications.
Very strange. Is this an emulator problem or Code Warrior problem. I did
a
search on the Palm-dev-forum knowledge database and found out an article
about the option
#pragma stack_cleanup on I thought the newer version of Code Warrior
resolved the stack cleanup problem and I don't have to set this parameter
(as it would increase the program size and slow down the execution).
Any suggestions?
Thanks,
George.

port to WinCE
Hi group, Is there any lib or recomendations on porting Palm app to WinCE with focus on reusing much of the code. I managed to implement parts of Palm APIs under WinCE. Any ideas?

FrmGetObjectPtr compliation error
Hello,
I'm using an older version of Code Warrior (7.0) to compile the following
code and got some compliation errors. Since I'm new to Palm Programming, I
don't know what I did wrong. This code is from the Palm OS Programming
Bible sample code hello. I compare that code to some other sample codes,
they all use simliar syntax in FrmGetObjectPtr.
Could you give me some advice on what to do to resolve this error?
Thanks in advance,
George.
static void SaySomething(UInt16 alertID)
{
FormType *form = FrmGetActiveForm();
FieldType *field;
MemHandle h;
field = FrmGetObjectPtr(form, FrmGetObjectIndex(form,
MainNameField));
if (FldGetTextLength(field) 0)
{FldCompactText(field);
h = FldGetTextHandle(field);
if (h)
{Char *s;
s = MemHandleLock((void *)h);
FrmCustomAlert(alertID, s, NULL, NULL);
MemHandleUnlock((void *)h);
}
}
else
{
FrmCustomAlert(alertID, whoever you are, NULL,
NULL);
}
}
Error messages I got from Code Warrior:
Error : illegal implicit conversion from 'void *' to
'FieldType *'
hello5.cpp line 43 MainNameField));
Error : function call 'MemHandleLock(void *)' does not match
'MemHandleLock(_opaque *)'
hello5.cpp line 52s = MemHandleLock((void *)h);
Error : function call 'MemHandleUnlock(void *)' does not match
'MemHandleUnlock(_opaque *)'
hello5.cpp line 55MemHandleUnlock((void *)h);
Error : illegal implicit conversion from 'void *' to
'FieldType *'
hello5.cpp line 76 FrmGetObjectIndex(form, MainNameField));

Re(2): Development tool based on VB

For this i have studied the tutorial which comes with the CodeWarrior and i have realized that it is based on C++. Is there any development tool based on VB which will allow me to make my application for Palm OS devices. I have heard about AppForge and NSBASIC but i am confused as to which i should purchase. I don't want to make a wrong decision. My application requires a strong user interface and alot of mathematical calculations. There is also some database handling involved in it.

Re: development tool for making app. in Palm OS
Have a look at our product - I think you'll find it easy to use. http://www.nsbasic.com/palm George Henne NS BASIC Corporation http://www.nsbasic.com Hello i am a newbie to Palm OS. I have made some applications for PC (in VB 6.0) and Pocket PC 2002 and Pocket Pc 2003 (in Embedded Vb 3.0) But as far as Palm OS is concerned i am at a complete loss. I have started studying from the Code Warrior documentation and i have realized that it is very near to C++ programming. My question is that is there any development tool which i can use to make my application for Palm OS which is similiar to vb. Thanks in advance Mahrine __ Do you Yahoo!? Yahoo!

Problem with SelectDay on T3
On a T3 and the T3 Simulator, when I put a bitmap on a form using WinDrawBitmap, then call SelectDay, the bitmap is gone after returning. (The same happens with WinDrawLine, and perhaps others.) The bitmap reappears properly on all other devices, Palm OS 3.0 on. The SelectTime function, which is similar in many ways, works OK on the T3.
