I am trying to put the global find functionality into my app, and I am using
the code from The Developer's Guide book. Everytime I debug into it and
look at the UInt recordNum variable, its value is 65355 even after
initializing it to 0 and setting it equal to findParams->recordNum. What
the heck is going on?! Does this have something to do with the no global
variables rule when using the find? If so, what's the workaround?
code snippet:
void GlobalFind(FindParamsPtr findParams)
{
Err err;
Word pos;
UInt fieldNum;
UInt cardNo = 0;
CharPtr header;
Boolean done;
VoidHand recordH;
LocalID dbID;
RectangleType r;
DmSearchStateType searchState;
DmOpenRef dbP;
UInt recordNum= 0;
findParams->more = false;
// find the application's data file
err = DmGetNextDatabaseByTypeCreator(true, &searchState, APPT_DB_TYPE,
APP_FILE_CREATOR,
true, &cardNo, &dbID);
if (err) return;
// open the schedule database
CApptDBConnection* pApptDB = new CApptDBConnection;
if (!pApptDB) return;
dbP = pApptDB->GetDmOpenRef();
// display the heading line
header = (CharPtr) MemPtrNew(21);
StrCopy(header, "EagleSoft - Schedule");
done = FindDrawHeader(findParams, header);
MemPtrFree(header);
if (done)
findParams->more = true;
else
{
// search all of the fields; start from last record searched
recordNum = findParams->recordNum; // this doesn't seem to work???
for(;;)
{...
Thanks!
