using va_list twice?
does C99 or MSL (either will do) allow me to pass through a va_list twice
like below?
CharArray(const char *format, ...)
{
va_list vargs;
//get the length of the string
va_start(vargs, format);
uint32 size = vsprintf(NULL, format, vargs) + 1;
va_end(vargs);
//allocate the storage
char *data = (char *)malloc(size);
//print the string
va_start(vargs, format);
vsprintf(data, format, vargs);
va_end(vargs);
}

Codewarrior & template friend class
I was under the impression that the following code was legal.
Codewarrior gives me a "declaration syntax error" on the word friend.
Any language options I might have wrong?
template
class AAA
{
};
class BBB
{
template friend class AAA;
};

Unexplained Beep
I currently have this code to show a form, the form does some stuff (stuff currently commented out), and revert back to the calling form This code is executed in the calling form's event handler when it receives a menuEvent. After this code is executed and the form handler returns back to within FrmDispatchEvent I here a beep sound. This beep occurs before FrmDispatchEvent return to my app event loop. If I execute this code from a button press, no beep. Anybody know why it should cause a beep, and only from a menu event? FormPtr prevForm = FrmGetActiveForm(); FormPtr frmP = FrmInitForm(formID); FrmSetActiveForm(frmP); FrmSetEventHandler(frmP, handler); FrmDrawForm(frmP); /*will do something here when I get rid of this beep*/ FrmEraseForm(frmP); FrmDeleteForm(frmP); FrmSetActiveForm(prevForm); -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

USB Debugging + Serial Comms + Codewarrior
Is it possible to debug a palmos device via USB whilst performing serial communications over the 232 port? If so, will codewarrior V9 have any issues doing this?

WinDrawRectangleFrame under OS5
When I draw a rectangle frame using WinDrawRectangleFrame passing dialogFrame as the frame type, the results are slightly different to the frames drawn by the OS around modal dialogs. The corners are slightly less round. This only occurs in high desnity mode. Is it possible to get exactly the same frame as that of the modal dialogs?

m505 serial flow control
I'm opening the cradle 232 port on my m505 and leaving the default settings (which include flow control on the receive path as far as I know). Then I send down a whole lot of data (more than the receive buffer size) from my PC using hyperterm. The flow control lines never change state, and receive serial buffer just wraps around to the start (checked using SrmReceiveCheck). Is there anything special required to get hardware flow control working?

Re: Application copy protection
Why not issue a key which is some hash of the device serial number. The user enters it in once and the application stores it as a 'feature'. Each time the app runs, it checks for the presence of the key, and checks if it is valid against the devices serial number. This way, the user only has to enter the key once every time the software is installed, this shouldn't make them too unhappy. The software can be copied, but won't run without a valid key. The only way this can be broken is if someone dissassembles your app, locates the hashing code and discovers your hashing algorithm.

FrmAlert and Form width
The OS5 Sim is giving me a warning when I display an Alert from a form that isn't the full screen width wide. I havn't come across anything covering this in the docs. Do I really have to make my form the width of the screen? KP -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: FrmAlert in frmCloseEvent Handler
That's what I'm currently doing. There are several actions that can cause the FormA => FormB transition and the frmCloseEvent handler seemed the most appropriate place. Now I have a function which does the Alert and then calls FrmGotoForm.

FrmAlert in frmCloseEvent Handler
I am calling FrmGotoForm(FormB) to switch from FormA to FormB. In the frmCloseEvent handler of FormA I'm calling FrmAlert to check if the user wishes to save the currently open file to flash. The problem is that the FrmAlert event loop eats the frmLoad and frmOpen events for FormB. Once the Alert closes, I'm stuck without an open form. There are ways around the problem, I'm just surprised that I haven't come across this in the docs, has anybody else?.
