问题 I am trying to implement a server client program to send message in Android.Can you please say me what are the errors in my code and how to rectify them? The server is running fine but the client program has one error. This is the server code and this is running fine. package com.app.MyServer; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.ServerSocket; import java.net.Socket; import android.app.Activity; import android.os.Bundle;

问题 I am checking consecutive indices of a list and I want to execute same piece of code in case if the consecutive elements are not equal or if the list index is out of range. Here's what I'm trying for n in range(len(myList)) try: if myList[n]==myList[n+1]: #some code else: #if they are not equal then do something #same code should execute if exception raised: index error --> how do i do this? Is there a way to do this elegantly without having to repeat the same code in the except block somehow

问题 I have a situation where I want to utilise a custom sys.excepthook. When a program throws an exception the sys.except hook gets called and does some stuff. Example: import sys def ehook(exctype, value, traceback): t = 'Keys' if exctype == AttributeError and value.args[0].split("'")[1] == t: print "t %s" % (t,) else: sys.__excepthook__(exctype, value, traceback) sys.excepthook = ehook class Keys(): @staticmethod def x(): print "this is Keys.x()" if __name__ == "__main__": Keys.x() Keys.noexist

问题 I apologize if the title is vague. I did not know how else to reference this question. I have code which forces the length of any TL values to be a length of 6 numbers following "TL-", and does the same with CT values to a length of 4 following "CT-". If it is too short, 0s are added after "TL-"; if it is too long, 0s are deleted from right after "TL-". TL- 0012 -> TL-000012 TL-0008981 -> TL-008981 TL - 008 -> TL-000008 The code gets the 6 numbers after finding a string "TL", puts "TL-" in

问题 How can we handle the MultiException of jersey which contains a list of Throwable objects? The exception mapper technique works fine in the case of one exception, but how can I handle multiple exceptions? 回答1: You can get the list of exceptions by calling getErrors() on the MultiException. The method defined in MultiException class is: public List<Throwable> getErrors() { synchronized (this.lock) { return Collections.unmodifiableList(this.throwables); } } In your mapper you can use this list

问题 File Name: location.xml <?xml version="1.0" encoding="utf-8" ?> <locations> <location id="1" position="Holiday" /> <location id="2" position="Time Off" /> <location id="3" position="Training" /> </locations> I am trying to populate a combobox with the "text" from position. The id is not necessary at this time. My C# Code var obj = XDocument.Load("location.xml"); comboBox1.DisplayMember = "LocationPosition"; comboBox1.ValueMember = "LocationID"; comboBox1.DataSource = obj.Descendants("location

问题 Ok first off, Hi every one this is my first post. Right now to business, I have created an SQLCE database, created the data context and all the mappings and have successfully filled the database with a load of data. So far so good, now if I want to retrieve the data I get a problem. Code for getting data var codes = (from c in App.BonusDatabase.tbRawData select c).ToList(); Running that I get Specified cast is not valid. I'm guessing there is a value somewhere it doesn't like, how can I find

问题 I am trying to catch an exception in a legacy winforms applications but somehow the exception is always captured by the global exception handling. In the Program.cs I have the following code : Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.ThreadException += Application_ThreadException; Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); static void Application_ThreadException(object sender, System.Threading

问题 I have a question about spring. I make a connection with MQTT broker using Spring-Paho MqttPahoMessageDrivenChannelAdapter . Here is a java config part: @Bean @Description("mqtt inbound adapter: receives mqtt messages") public MessageProducer mqttInboundAdapter() { log.info("creating mqtt inbound adapter"); MqttPahoMessageDrivenChannelAdapter adapter = new MqttPahoMessageDrivenChannelAdapter( env.getProperty("mqtt.hostname")+":" +env.getProperty("mqtt.port"), "myClient", "#"); adapter

问题 In short, MSDN describes exception dispatching for user mode application like this: the debugger gets notified of the first chance exception (if attached) an exception handler aka. try/catch is invoked (if available) the debugger gets notified of the second chance exception (if attached) the system cares about the unhandled exception (typically: terminate the process) This sequence does not consider the presence of an unhandled exception handler. How does exception dispatching change when an
