Set SQL DateTime to Empty/Nothing in vb.net -


मेरे पास SQL ​​( दिनांकटाइम डेटाटाइप के) में एक दिनांक कॉलम है । किसी विशेष परिदृश्य के लिए, मुझे अपने ब्राउज़र में इसे रिक्त रूप में दिखाना होगा। मैंने कोशिश की 

  मंद DOB के रूप में नल योग्य (तिथि की तिथि) = दिनांक। अब मंद आंकड़े स्ट्रिंग के रूप में = DOB.Value.ToString ("डी") DOB = कुछ भी नहीं   
 लेकिन यह मुझे  डेटटाइम एक उचित प्रारूप में नहीं था कहने में त्रुटि देता है । 
 
 यहाँ क्या गलत है?

आप निम्न में से किसी एक को भी आज़मा सकते हैं: 

  मंद आंकड़े के रूप में स्ट्रिंग = IF ( DOB कुछ नहीं है, "", DOB.Value.ToString ("d"))

या 

  डायरेक्टिंग के रूप में स्ट्रिंग = "" यदि नहीं है तो डीबी कुछ नहीं है तो डीएटीस्टिंग = डीओबी.वैल। टॉस्ट्रिंग ("डी") समापन यदि

Django Celery - running scheduled tasks -

After several hours on this without the result, I really need help I'm able to run Django-Celery with my Django app and I scheduled tasks on it: dragon manage.py celeryd -E -B -l INFO Now it is time to produce and here it is that my pain begins. I have configured the cellarid as the daemon, it works, but scheduled tasks will not work. So I added -b to CELERYD_OPTS . My tasks are now run as scheduled, but these are the boring lines on my logs: [2014-02-17 22: 37: 30,738: debuts / main process] Beat: 5.00 Waking in seconds I just want to delete that line from my logs! I did not even understand what it meant. So I had configured the Selerbeat daemon, thinking it would be a cleaner and suggest a solution to the production environment. Unfortunately, when I stop the celerybeat daemon, it creates a log and a PID file but scheduled tasks do not work. Info / main process] green: ... [2014-02-17 19: 15: 41,921: information / main process] write entries. .. [...
