.net - SqlConnection.ClearAllPools, what is cleared? -

September 15, 2014

I have an application that does not allow SqlConnection.ClearAllPools < / Code>.

  There is a case where the connection is still there. This connection was created in another application domain. 
  So I wonder which connections are closed from  SqlConnection.ClearAllPools ? 
   Are there connections only opened by calling process (or appmen)? 
  All the connections opened by this machine? 
  ...? 
  
  This only closes all the connections opened by the calling process. It emits all the connections pools that are bound to process. : 
   Connection pools and connection strings go hand in hand Each connection pool is connected with a separate connection string and that too, it is specific to the application what it means in return - each A separate connection pool is maintained for separate process, AP domain and connection string.

IronPython in C#: No module named xmlrpclib -



    I am trying to create a web application with an interactive console for IronPython. When I try to import xmlrpclib into the General console of IronPython, it works. However, if I use IronPython inside my C # code, then it does not put an exception "a module named xmlrpclib", is it a known issue? Any solution to solve this issue?   Here is the code:    var testcode = @ "import xmlrpclib; apiarver = xmlrpclib.ServerProxy ('address', allow_none = true); print APIServer.Hello () ; "; Mystream str = newest Mystream (); ScriptEngine Engine = Python. Cretegenine (); Engine. Retyme.io asset output (str, system text encoding. ASCII); Engine. Serial.io.setuperoutput (str, systemtext.edcoding.aspx); ScriptScope scope = engine.CreateScope (); ScriptSource src = engine.CreateScriptSourceFromString (testCode); Src.Execute (scope); Sorry for the silly question, it has come to know that there is a path used by IronPathon inside me.       The C # code was not correct. I ...






qt creator - QtCreator importing makefile projects -



    Have you ever tried importing Classic C ++ / project into Qt Creator?   Say that I wanted to use some libraries in my GUI project, which must be created. how can I do this?      In Qt Creator 2.0.1 you can import projects using only * * Cmake, * .creator, * .pro or * .qmlproject   Then switch to cmake and you can import the project into Qt builder (Welcome tab -> Open project ...).
