vb.net用GetBytes时GBK特殊字符乱码,中文正常
GetBytes 方法是获取字符串vb.netgbk的字节数组序列vb.netgbk,与之相反的是
Encoding.GetString 方法vb.netgbk,把字节数组还原成字符串,参考:
vb.net 如何嵌入地图
新建一个文件,写入下面的代码:
!doctype html
html
head
meta name="viewport" content="initial-scale=1.0, user-scalable=no" /
meta http-equiv="Content-Type" content="text/html; charset=gbk" /
titleBaidu Map V1.2/title
script type="text/javascript" src=";services=true"
!-- add baidu map api --
/script
/head
body
div id="container" style="width: 600px; height: 400px;"
/div
/body
/html
script type="text/javascript"
var map = new BMap.Map("container"); // new Map
var point = new BMap.Point(116.397128, 39.916527); // Location, (经度, 纬度)
map.centerAndZoom(point, 15); // show Map
// 添加缩放功能
map.enableScrollWheelZoom();
map.enableKeyboard();
/script
保存到程序exe同一目录下,文件名:map.html
然后BUTTON点击事件:
WebBrowser1.Navigate(Application.StartupPath "\map.html")
这样就可以了
ps:经纬度可以到百度地图官网去获取
或者到: 去生成代码
vb.net 写入sqlite 中文时,在sqlite显示的是乱码,这样不好管理,请问怎么解决?
并非SQLite的乱码。windows的命令行console窗口只支持GBK的汉字。。
数据库内容为unicode/utf8/utf16等其vb.netgbk他汉字编码时vb.netgbk,将不能在win命令行窗口显示正确。
建一个console.bat文件vb.netgbk,写上
chcp 65001
cmd
然后建一个快捷方式到这个文件vb.netgbk,把快捷方式的字体改成宋体
然后就可以使用sqlite命令并显示utf-8的内容
或者,库中的文字也用GBK编码,就可直接显示。
vb.net获取webbrowser网页中所点击的链接的文字
vb.netgbk你vb.netgbk的问题应该是如何提取网页中vb.netgbk的文字吧。下面代码可以获取所有网页源码vb.netgbk:
Sub Main()
Dim cl As New WebClient
Dim all As String = cl.DownloadString(";ie=GBK")
Console.WriteLine(all)
Console.ReadLine()
End Sub
具体要获取某种类型的元素vb.netgbk,可以用正则表达式。
vb.net怎么把汉字转换为GB2312编码,例如“广东”变成%B9%E3%B6%AB
GB2312是GBK编码的子集,使用GBK编码函数即可
'GBK编码(结果以百分号%进行分隔)
Public Function GBKEncode(ByVal sInput As String) As String
Dim ret_GBKEncode As String = ""
Dim i As Integer
Dim startIndex As Integer = 0
Dim endIndex As Integer
Dim x() As Byte = System.Text.Encoding.Default.GetBytes(sInput) '字符以及字符串在vb2008中都是以unicode编码存储的
endIndex = x.Length - 1
For i = startIndex To endIndex
ret_GBKEncode = "%" Hex(x(i))
Next
Return ret_GBKEncode
End Function
'GBK解码
Public Function GBKDecode(ByVal sInput As String) As String
sInput = sInput.Replace("%", "")
Dim ret_GBKDecode As String = ""
Dim sLen As Integer = sInput.Length
Dim n As Integer = sLen \ 2
Dim sBytes(0 To n - 1) As Byte
'转化为字节码
For i As Integer = 1 To n
sBytes(i - 1) = CByte("H" sInput.Substring(2 * i - 2, 2))
Next
'将字节码转化为字符串
ret_GBKDecode = System.Text.Encoding.Default.GetString(sBytes)
Return ret_GBKDecode
End Function
求教vb.net utf-8 解码
Public Function GBKDecode(ByVal sInput As String) As String
sInput = sInput.Replace("%", "")
sInput = sInput.Replace(":", "")
Dim ret_GBKDecode As String = ""
Dim sLen As Integer = sInput.Length
Dim n As Integer = sLen \ 2
Dim sBytes(0 To n - 1) As Byte
'转化为字节码
For i As Integer = 1 To n
sBytes(i - 1) = CByte("H" sInput.Substring(2 * i - 2, 2))
Next
'将字节码转化为字符串
ret_GBKDecode = System.Text.Encoding.UTF8.GetString(sBytes)
Return ret_GBKDecode
End Function
'上面是函数,调用方法
MsgBox(GBKDecode(":%E9%80%81%E8%BE%BE%E6%97%A5%E6%9C%9F%20%E9%80%81%E8%BE%BE%E6%97%B6%E9%97%B4"))
