vb 字符串由ansi转 utf8代码
如题 --------------------编程问答-------------------- 没人跟帖？ 分要是不够在加 --------------------编程问答-------------------- http://topic.csdn.net/u/20100306/20/03450634-dcd6-4982-947e-a225a262745f.html --------------------编程问答-------------------- http://topic.csdn.net/u/20100306/20/03450634-dcd6-4982-947e-a225a262745f.html --------------------编程问答-------------------- 这里面有现成的函数http://blog.csdn.net/SupermanKing/archive/2010/11/05/5989227.aspx --------------------编程问答--------------------
这个问题不是没解决吗 --------------------编程问答--------------------
没看懂 --------------------编程问答-------------------- 弄错了，上面是转回来的，这个才是
http://blog.csdn.net/SupermanKing/archive/2008/10/16/3082860.aspx --------------------编程问答-------------------- 不过 http://blog.csdn.net/SupermanKing/archive/2010/11/05/5989227.aspx 的
UTF8ToUnicode 函数是很值得你参考的，是整个UTF-8解码过程，没有用API，如果把过程逆
向还可做出编码过程。

UTF-8在VB中是以字符串的形式显示的...字符串是2位而UTF是3位...所以必定产生乱码...在此最好的解决办法就是用本函数啦~--------------------编程问答--------------------

我要是能百度到 还来这问吗 --------------------编程问答-------------------- 这不帮你找了么
上面的代码试过了？
--------------------编程问答--------------------
你的问题在网上早就有资料了，百度一定能找到，只是用不用心，想不想找的个人问题。
像这种问题，即使CSDN也回答过不知多少贴，你都不去搜索一下就问了，别人给你连接
也是当然的。 --------------------编程问答--------------------
楼主太监了不等于方法没用。 --------------------编程问答--------------------
融汇贯通才是最重要的
