Here's just a guess:
If an app hasn't been run, then it is very likely that the prefs haven't
been initialised yet. Specifically, When MemoPad is run for the first time,
it will initialise the prefs, and therefore prefs.currentCategory. (I'm only
guessing here, I haven't looked at the source code yet)
Therefore, if it hasn't been run, then prefs.currentCategory hasn't been
initialised, giving you your problem.
Maybe you should check to see whether the prefs have been initialised or
not:
prefsVersion = PrefGetAppPreferences(sysFileCMemo, 0, &prefs,
&prefsSize, TRUE);
if (prefsVersion == noPreferenceFound)
// Then there won't be a valid prefs.currentCategory!
Hope this helps.

Subject: POSE Error: Bad Category - ???
I have a form that displays a Catetory Popup Trigger and my
app initialized the display to MemoPad's current category. But
it appears that there is some problem with the category, initially,
until I go into MemoPad, once.
I am consistently getting this error, in POSE:
"Category.c, Line:462, Bad Category". This error goes away
after I go into MemoPad, once, after the error. The error
will repeat every time I start the app, until I go into MemoPad.
Then I don't see the error again.
Here is the code to setup the initial label for my Category Popup
Trigger.
void GetMemoDBPrefs(void) {
MemoPreferenceType prefs;
Word prefsSize;
Int prefsVersion;
prefsSize = sizeof(MemoPreferenceType);
prefsVersion = PrefGetAppPreferences(sysFileCMemo, 0, &prefs,
&prefsSize, TRUE);
CurrentCategory = prefs.currentCategory;
CategoryGetName(ImportDB, CurrentCategory, CategoryName);
CategorySetTriggerLabel(GetObjectPtr(trgCategory), CategoryName);
}
I think what is happening is that CategorySetTrigger is trying to set
an invalid category. So, when I go into MemoPad the first time, the
value is set correctly. Just a guess.
But if I am right, what is the initial value of category? And how
do I prevent this initial error?
Any idea what could be causing this?
