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 (); }}

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

Is there an open source WebSockets (JavaScript) XMPP library? -

-
Has anyone written the open source XMPP library that uses the websacet and is being run by a browser? We do not yet have a standard XMPP that can enforce the server, Must be adequately faced before it may be necessary The first step is to eliminate WebSAT standardization. It seems that it can be in an IETF Haib working group, which has not been approved by the IESG so far in the writing time (see) a few weeks ago (Hiroshima), a hybrid bird-of-a-feather in IETF ( BOF), which went very well. WebSketches have a constant reference, and it seems to be systematically organized, one will make XMPP binding for webmasters, possibly with a bar for every webset frame. Edit: Jack Moffitt has written an IETF can be used with the first pass on a protocol. Warning . It is still likely to change fast enough, only apply it if you are ready to wrap it completely later.
