c# - .NET database connection pooling error occurred? -

-

मैंने web.config फ़ाइल में कनेक्शन स्ट्रिंग बना दिया है। 

  & lt; connectionStrings & gt; & Lt; नाम जोड़ें = "Test_registration" connectionString = "डेटा स्रोत = DOTNET \ SA; प्रारंभिक कैटलॉग = परीक्षण2009; उपयोगकर्ता आईडी = प्रशिक्षु; पासवर्ड = प्रशिक्षु 123" प्रदाता नाम = "System.Data.SqlClient" / & gt; & Lt; / ConnectionStrings & gt;

और सीएस फ़ाइल में एक कनेक्शन खोलने के लिए एक कन्स्ट्रक्टर बनाते हैं। 

  सार्वजनिक मुख्य_कनेक्शन () {sql_conn = नया SqlConnection (System.configuration.configurationManager.ConnectionStrings [ "Test_registration"] ConnectionString)। sql.conn.open (); }

लेकिन सर्वर पर प्रोग्राम के रनटाइम पर मुझे कनेक्शन पूलिंग त्रुटि मिल रही है।

क्या कोई मुझे बता सकता है कि मुझे कनेक्शन बंद क्यों करना चाहिए? मेरी प्रोजेक्ट सीएस फ़ाइल की वेब। कॉन्फिग फाइल में जहां मैं कनेक्शन खोलता हूं?

मैं उस क्लोज़ () कथन को केवल एक बार लिखना चाहता हूं जब कि मैं केवल एक बार कनेक्शन शुरू करता हूं।

यहां कनेक्शन स्ट्रिंग सेट करें।

फिर निम्न कोड का उपयोग करें। (Sql_conn कनेक्शन ऑब्जेक्ट का नाम है) 

  try {sql_conn.Open ()} } पकड़ (अपवाद) {यदि (sql_conn.State! = ConnectionState.Closed) {sql_conn.Close (); sql_conn.Open (); }}

Just want to know how I will create UIPickerView in a UIActionSheet with a simple array. Well, I really know how to put it in an action sheet but I like my way because it is more for my app, thanks, but I I also want to know how to put options in UIPKviewView, I just have an array with colors already on top of that part: red, green, blue, yellow, black, etc. in this, but I want to know how it In the preview d L'be if I am using the already Instifrem:? Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
