什么意思呀

[沈逸]

不好同时
任何东西都是 要先来后到的

[_-_-_-_-]

？？？？

[lucbesson]

我的意思是：client 的richtextbox怎么样发送图片+文字的内容，server如何接收 ？

继续收集意见

[新鲜鱼排]

不是很懂，帮顶

[cnming]

肯定要分开传，建立排队机制

要传输这些内容，首先要把它们转换为byte数组

真个题太大，不好一一说，你还是自己去学习，当中有疑问的再问

如果有耐心，建议去下载一个myicq的源码来看看，这是开放源码的

[lovelxj]

不懂这个机制 楼猪 要不介绍一下吧
你这个的用途

[pc_csharp]

QQ里把函数告诉你了.

但是把图片放到stream里面怎么样让richtextbox显示我不知道.

}
例如这样一个图片的rtf代码，怎么样把它再变成图片 ？
----------------------------------------------------

楼上那位老师的定义传协议，有朋友能清楚的讲述一下吗 ？


谢谢

[athossmth]

winform or webform?

[henryfan1]

你定义传协议,简单的文字加图片信息可以定义如下:
<Message>sfsddfsd<IMG>SDFSD</IMG>SFS<IMG>SDFS</IMG></Message>;
byte是可以转成字符的,分解后把IMG部分转成byte用Image类加载就可以还原图象.

winform

无奈的结帖啦

[milkbb]

这么快就结了？我昨天培训去了，很无奈啊。
我做了一个，很简单，运行良好，帖下面了。
有一点要注意的，UPD包是限大小的，包太大是发不出去的，好象是4096字节，大的要分包发，我的程序里没有分包。图片用COPY&PASTE搞。
