Doh - I meant to include the code in the previous email...it follows.
If anyone can help, I'd be most appreciated.
John.
//Extract from form handle event
else if (event->eType == tblSelectEvent)
{
rowselected = true;
tbl = GetObjectPtr(ViewTable);
currentRow = event->data.tblSelect.row;
column = event->data.tblSelect.column;
currentrecord = TblGetRowID(tbl, currentRow);
if (column == completedColumn)
{
if (TblGetItemInt (tbl, row, column) > 0)
comp = true;
else
comp = false;
ViewChangeCompleteStatus (row, comp);
}
handled = true;
}
/***********************
* Function: ViewChangeCompleteStatus *
* Objective: Change status of checkbox in ViewIssue *
************************/
static void ViewChangeCompleteStatus (Word row, Boolean comp)
{
VoidHand tempH = NULL;
RecordTypePtr temp = NULL;
ULong offset;
RecordTypePtr nilPtr = 0;
Err error;
//Update the record to reflect the new completion status.
offset = (ULong) &nilPtr->completed;
tempH = DmGetRecord(DB, currentrecord);
if (tempH == 0) return;
temp = MemHandleLock(tempH);
error = DmWrite(temp, offset, &comp, sizeof(Boolean));
MemPtrUnlock(temp);
DmReleaseRecord(DB, currentrecord, true);
// If completed issues are hidden redraw the list form
if (! showCompleted)
{
ApplyFilter();
DmInsertionSort(IssueDB, (DmComparF *) &CompareIssueRecords, 0);
FrmGotoForm(View);
}
// If completed items are viewed, update the table.
else
FrmGotoForm(View);
}

Check boxes do work in both directions (check and uncheck). It sounds like
your handler logic is flawed. If you could post some of the code, someone
on the list may be able to point out the exact problem.

Subject: Problem with completing a to do-type record
>
> I've got an application that allows the user to mark a record 'complete'
in the same way as the standard To Do application.

i.e. you can mark it as complete but cannot then unmark it.

guessing it's something to do with the way table events are handled - can
anyone help?
