1st paragraph |
Just would like to report that although clumsy errors from Graffiti are a good
rationale not to obfuscate password fields on Palm handhelds, Blueiceresearch came up
with a pretty clever work-around in their Multipass application.
http://blueiceresearch.com/
What they implemented is a password field that obfuscates the password letter that
has just been entered after 1 second of clear text display.
That way, password is obfuscated hence adding a little bit more of security while
leaving the user with the opportunity of checking its Graffiti writing.
Might be a Power User feature though.

Installing the 4.0 SDK: Point 6. |
WINDOWS USERS ONLY:
The book states that to mount PalmDev you use:
mount -f "C:PalmDev" /PalmDev
Using this I encountered this error:
/PalmDev/sdk-4/include/Core/System/AlarmMgr.h:116: badly punctuated parameter list in
`#define'
Checking the syntax for mount specifies that the switch -t (text files get
line
endings) is set a s default. This is not the case. To correctly create the mountpoint
for use with the sample project use this mount command:
mount -f -t "C:PalmDev" /PalmDev
Hope this helps. Saved me some time

Installing PilRC: Step 2. |
Step 2, says to copy pilrc.exe to C:cygwinusrin
Running make, after fixing the mount issue (see errata page 124). I received the
following error:
( cd GCC/; rm *.bin; pilrc -I ../Src/ ../Src/Resources.rcp)
rm: cannot remove `*.bin': No such file or directory
pilrc: not found
make: *** [GCC/bin.stamp] Error 127
The location of pilrc.exe appears to be incorrect. Firstly there are no other binary
files in the usr/bin directory. Instead I copied pilrc.exe to C:cygwinin. This
fixed the problem.

section "Cloning the Sample Project" |
First. You reference a directory named "OreillyStationery" - the name of the directory
is actually named "OReillyStarter" after the download completes.
Second. I installed the latest version of Cygwin (probably a bad move) from
http://sources.redhat.com/cygwin/ (ver. cygwin-b20). The setup.exe creates an entirely
different directory structure than the version you probably used for creating the OReilly
Sample project (I deduced this from the the following error I received after attepmting to
make MyProject: "m68k-palmos-gcc: command not found"). The gcc app is now located in
c:cygnuscygwin-b20H-i586-cygwin32in.
I'm still trying to get the sample to run but am currently stuck. The Cygnus website
has a ton of information to sort through and they have made it very clear, esp. with
acronyms like "RTFM", that unless you actually purchase their product you are SOL.
Is there a later version of the Sample Project that's designed to work with cygwin-b20?

Cloning the Sample Project |
The text states that you should be able to cd to "MyProject" and run a make.
Unfortunately, I downloaded the latest Palm SDK (version 4.0). Apparently, the new
SDK contains a few more include files and a different directory structure. As a
result, I got errors concerning a bad use of PalmOS.h. The solution to this problem
is to run palmdev-prep from the command line in Cygwin.

Last line of GetStackSpaceUsed() |
The return value for GetStackSpaceUsed() is
return (UInt32)
Abs((char*) &aStackBasedVariable - (char*)bottomOfStack);
I believe it should be:
return (UInt32)
Abs((char*) &aStackBasedVariable - (char*)topOfStack);
My reasoning is:
The stack that is used is from the top of the stack (say at location 1000) to the
aStackBasedVariable (say at location 750). This would give the number of bytes on the
stack, ie. used.
If you use the bottomOStack this would give you the number of free bytes left on the
stack.
1000 (TOS) ---+
... {Used stack space } |
0750 (aStackBasedVariable ) ---+
... {Unused stack space }
0000 (BOS)

controlID in FrmGetControlValue and FrmSetControlValue should be object index instead.
