Wait 20 Seconds In Timer Before Executing Next Line Without Thread.Sleep.C# -

-

i'm trying wait 20 seconds before adding + 1 value (int), want without thread.sleep.

this code, way i'm not pro programmer.

private void refresh_app_timernh_tick(object sender, eventargs e) {     label18.text = "timer activated";     int = 0;     = + 1;     if (i == 16)     {         = 0;     }     else     {      }     if (i == 1)     {         webbrowser1.refresh();         useridlabel1.backcolor = color.red;         label20.text = "+1";      //**i want add 20 second gap here**         = + 1;     }     else     {      }     if (i == 2)     {         webbrowser2.refresh();         useridlabel2.backcolor = color.red;         label20.text = "+2";         = + 1;     }     else     {      }     if (i == 3)     {         webbrowser3.refresh();         useridlabel3.backcolor = color.red;         label20.text = "+3";         = + 1;     }     else     {      }     if (i == 4)     {         webbrowser4.refresh();         useridlabel4.backcolor = color.red;         label20.text = "+4";         = + 1;     }     else     {      }     if (i == 5)     {         webbrowser5.refresh();         useridlabel5.backcolor = color.red;         label20.text = "+5";         = + 1;     }     else     {      }     if (i == 6)     {         webbrowser6.refresh();         useridlabel6.backcolor = color.red;         label20.text = "+6";         = + 1;     }     else     {      }     if (i == 7)     {         webbrowser7.refresh();         useridlabel7.backcolor = color.red;         label20.text = "+7";         = + 1;     }     else     {      }     if (i == 8)     {         webbrowser8.refresh();         useridlabel8.backcolor = color.red;         label20.text = "+8";         = + 1;     }     else     {      }     if (i == 9)     {         webbrowser9.refresh();         useridlabel9.backcolor = color.red;         label20.text = "+9";         = + 1;     }     else     {      }     if (i == 10)     {         webbrowser10.refresh();         useridlabel10.backcolor = color.red;         label20.text = "+10";         = + 1;     }     else     {      }     if (i == 11)     {         webbrowser11.refresh();         useridlabel11.backcolor = color.red;         label20.text = "+11";         = + 1;     }     else     {      }     if (i == 12)     {         webbrowser12.refresh();         useridlabel12.backcolor = color.red;         label20.text = "+12";         = + 1;     }     else     {      }     if (i == 13)     {         webbrowser13.refresh();         useridlabel13.backcolor = color.red;         label20.text = "+13";         = + 1;     }     else     {      }     if (i == 14)     {         webbrowser14.refresh();         useridlabel14.backcolor = color.red;         label20.text = "+14";         = + 1;     }     else     {      }     if (i == 15)     {         webbrowser15.refresh();         useridlabel15.backcolor = color.red;         label20.text = "+15";         = + 1;     }     else     {      }     if (i == 16)     {         webbrowser16.refresh();         useridlabel16.backcolor = color.red;         label20.text = "+16";         = + 1;     }     else     {      }     refresh_app_timernh.stop();     label18.text = "timer de-activated";     refresh_app_timernh.start();  }

i think might easy not me, because i'm new c#

first off, tim s's answer -- break logic smaller chunks , simplify timer logic -- good. answer specific question, "how delay between statements without sleep", is: make method async , use await task.delay(...).

you right avoid sleep; using bad programming practice, , hang application. await task.delay asynchronous wait -- is, method returns immediately, app keeps on processing ui messages, , when delay done, program schedules remainder of method execute later.

note during asynchronous wait, design messages keep on getting processed. if 1 of messages causes event handler run again can confusing situation of having multiple control points in same non-recursive method. try avoid that.

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

here's current code creating index jsonb. index("mytable_data_idx_id_key", mytable.data['id'].astext, postgresql_using='gin') but got error. sqlalchemy.exc.programmingerror: (psycopg2.programmingerror) data type text has no default operator class access method "gin" hint: must specify operator class index or define default operator class data type.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
