阅读更多关于 How do i send messages from one computer to another using vb.net?

问题 Ok so i've been wanting to do this for a few years now and it amazes me that no one can come up with a solution... i want to write a program (preferably in vb.net) that can send a message to another computer (or device) that is connected to the same network as me. I want the message to appear on the other computer (or device) in a popup message box. Also, it would be ideal if this could be done through some sort of bluetooth connection, if not then local ip connection will do. I don't know

问题 Anyone know any good examples on how to setup a pjsip client to receive messages. I can send messages from the client using: pjsua_im_send(sip_acc_id, &to, NULL, &msgbody, NULL, NULL); to any number. But I have no idea what to do to receive messages into the already registered sip account. Any info would be greatly appreciated. Note: I can only use pjsip and no other library. Edit: Some new stuff I found: http://trac.pjsip.org/repos/ticket/1070 http://www.pjsip.org/release/0.5.4/PJSIP-Dev

阅读更多关于 How to display p:fileUpload invalidFileMessage in p:growl

问题 I'm using <p:fileUpload> which is restricted to PDF only. However, the invalidFileMessage shows inside the <p:fileUpload> component. How can I show it in <p:growl> instead? <p:fileUpload allowTypes="/(\.|\/)(pdf)$/" invalidFileMessage="File is Invalid. Only PDF files are allowed" /> 回答1: You can't handle this server side. The file type is validated at client side without hitting any code in server side. So, any suggestions which suggest to manually create FacesMessage and/or explicitly add <p

Protocol Terminology: Message versus Packet

阅读更多关于 Protocol Terminology: Message versus Packet

问题 In practice, what is the most appropriate term for the communications transmitted over a network in higher level protocols (those above TCP/IP, for example)? Specifically, I am referring to small, binary units of data. I have seen both "message" and "packet" referred to in various client/server libraries, but I was interested in the community's consensus. 回答1: These are definitely messages. A "packet" is a layer-3 (in ISO terminology) protocol unit, such as an IP packet; and a "datagram" is a

Android4.0 Message 中添加附件

阅读更多关于 Android4.0 Message 中添加附件

一，基本情况不说废话，先直接上图，大致情况就是，在一则New Message中添加一些附件（图片，视频，声音等）和信息一起发送，如下图；二，基本思路其实，这就类似于我们的拍照上传，是采用一样的处理方法，这里选择临时拍一张照片作为一起发送的附件，即上图中的Capture Picture。主要步骤： 1）点击Capture Picture时，会启动系统Camera应用程序来拍照；主要使用startActivityForResult (Intent intent, int requestCode)方法来启动Camera程序； 2）拍摄照片；这里就是用Camera进行拍照，这里不做介绍； 3）保存照片，并将照片数据返回给Message应用；主要用到一个setResult(int resultCode, Intent intent)方法，返回到原调用程序，关闭Camera; 4）在Message应用中处理返回的数据；重写onActivityResult(int requestCode, int resultCode, Intent data)方法来处理返回的数据；三，具体流程首先，我们已经启动Message-->New Message-->Attachment，在Message主活动ComposeMessageActivity中有一个addAttachment(
