Creating calculations using SQLite and C#/WPF -
i developing small time-management app (so can learn c#/wpf). need know best way return calculations various textblocks on 1 of forms.
i have table called "tblactivity" , need calculate how many times values exist. in old days of vba, have used dsum or dcount, i'm not sure the efficient/correct/fastest way return sort of data (the fields indexed way).
if want query table whole this:
int rowcount = tblactivity.rows.count();
if want count column meets criteria, run select statement
datarow[] selectedindexcountrow = tblactivity.select("index = 12 , index2 = 'something'");
what can still if need display data , count
int count; foreach row datarow in tblactivity.rows { string valuefromtable = row("column"); //display data if must, count += 1; }
