java 如何模仿QQ聊天框那样可以显示文字与图片啊？
两种解决办法,
第一种使用纯java的方式,使用组件JTextPane 或者JEditorPane 来显示图片和文字
第二种使用JEditorPane,但是里面存放HTML代码. 用HTML来控制文字和图片的显示

给你个Socket/ServerSocket写的小例子,看看能不能帮到你哦:
先运行ServerGUI,启动服务器端,再运行ClientGUI,双方就可以发送字符串了...

php如何生成加粗或者斜体的文字样式图片加粗或者斜体的文字可以用php的函数控制.我想你是想生成验证码图片是吗?如果是想生成验证么图片有几个函数可以考虑imagecreate($length,$height)创建图片.参数是图片的宽度和高度imagecolorallocate($image,$r,$g,$b)设置背景色,rbg就是图片的三色rgb参数.这个可以由传
一个java程序为什么不能显示图片？编译出错的原因是因为JPanel是没有setIcon()这个方法!你可以试试用JLabel代替JPanel看看行不行,但这样只是可以用setIcon(),若只就你贴出的代码看,是可以用JLabel,但能否正确编译及运行还要视乎其他代码!java程序在linux下无法显示图片1.调用"images"文件夹里的文件放在ImageIcon里显示
PHP如何获取图片的哈希值啊。。你好，哈希算法很多，自带有，sha1函数跟md5函数，获取图片的哈希值要读取内容去运算，如$file=file_get_contents("图片路径");echosha1($file);//哈希值，echomd5($file);//md5值，这两个都是摘要。谢谢php修改文档属性摘要的标题怎么设置php修改文档属性摘要的标题设置方法：1、
