<< Hello All-
I'm trying to access functions in the String manager API and get a major
failure at simulation time within POSE. I'm running Code Warrior R6 with
version 3.0a6 of POSE. Here is my simplified code segment:
#include <Pilot.h>
#include <StringMgr.h>
static Boolean TimerFormHandleEvent(EventPtr event)
{
CharPtr strptr, dbgptr;
// other variable declarations here
...
strptr = "00:00.0";
dbgptr = "12:34.5";
// other case statement code here for handling the various events on the
form...
switch(event->data.ctlSelect.controlID) {
case TimerFormRecalcButton:
StrCopy(dbgptr, srcptr);
break;
}
When I am running and get to the string copy line, I get a failure with a
dialog window (with no error description thank you very much) and the Close
button. The Error dialog is just an empty window with a couple of ASCII
graphic (garbage) characters in it.
I've got the prototype properly included (right?). Is there something else
I need to do from within CW to access functions of the string manager?
Regards

I'm a little suspicious of your StrCopy() function call. I would imagine
that you shouldn't be using StrCopy() when it is pointing to the constant
string "12:34.5". I tried it on my compiler (BorlandC++/Win98), and it
worked fine, but I don't know why. I would have figured that it would have
given me an exception for trying to write into memory that only has read
access. Just for kicks, try something like this instead:
Char dbgptr[10];
static Boolean TimerFormHandleEvent(EventPtr event)
{
CharPtr strptr;
// other variable declarations here
...
strptr = "00:00.0";
StrNCpy(dbgptr, "12:34.5", sizeof(dbgptr));
// other case statement code here for handling the various events on the
form...
switch(event->data.ctlSelect.controlID) {
case TimerFormRecalcButton:
StrNCopy(dbgptr, srcptr, sizeof(dbgptr));
break;
}

PS: I've made 'dbgptr' a global variable instead of a function variable since
you probably need its lifetime to last as long as the form object that you
are using it with.
PPS: In your StrCopy() call, your second string parameter was listed as
'srcptr' instead of 'strptr'. Was that a typo?
