问题 I'm building my first app using MVVM and I stuck. Using the messenger to communicate other ViewModels about some changes was working ok until I tried to build an observablecollection of objects. I have a class (myClass) that contains a list (innerList). Elements of innerLists should send message to it's parent (to communicate that they changed or should be deleted). I'm sending a message from the innerList object. This message is registered in the myClass. The problem is that I need to create

问题 Does anybody know if kafka.javaapi.producer.Producer can be reused among several method invocations (e.g. several send(...)) or it should be closed each time? 回答1: Yes, it can surely be reused. Producer creation is pretty slow operation because it requires establishing connection to all partitions (and probably zookeeper). So, Producers should be reused when possible. 来源： https://stackoverflow.com/questions/14070008/apache-kafka-java-producer-reusability

Imagine two users are using a windows forms application, when User A opens a particular form a lock is applied to the data record underlying the form so that only that user can make changes at that time. User B has a list of all records (in a grid) which among others contains a reference to the record already opened by User A. What we want to do is when User A opens the records User B's list of records is updated to show a lock icon

问题 Microsofts's WCF is easy to work with when you create Web services where each message has it's own Web method. WCF generates all of the WSDL and everything is easy. What I want to do is have one Web method that accepts multiple different messages (I don't want to add a mew method every time I add a new message type). The messages themselves will have header information that identify the message type. Once I know the message type, I'll know the structure of the rest of the message. The only

问题 I have App "A" in android device "A" and i have the App "A" in android device "B" . Is it possible for me to send the notifications between the devices through WIFI?? Thanks in advance 回答1: There's a variety of ways to do this, but ultimately it all boils down to have an app running on the second device that receives some trigger to show a notification. Some examples.... You can have an app with a open server socket on device b and then discover and connect to it to send a message that

问题 I am receiving the following error when I try to access IBM Mqueue from Tomcat. com.ibm.msg.client.jms.DetailedJMSException: JMSMQ1112: The operation for a domain specific object was not valid.
