VB.net 字符转换问题 字符（汉字、数字、字母、符号）>gb2312>unicode>utf8， 以及逆转的方法

字符编码转换吗?

1.字符与gb2312(gbk的子集)：

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

2.Unicode字符串为UTF-8

Imports System.Text

Public Function StringAsUtf8Bytes(ByVal strData As String) As Byte()

Dim bytes() As Byte

bytes = Encoding.UTF8.GetBytes(strData)

Return bytes

End Function

'这里可以类推出好几种。

vb.net怎么做中文语音识别程序

首先添加一个系统的语音COM组件的引用microsoft speech object library然后在程序中声明一个语音类dim RC As SpeechLib.SpSharedRecoContext这个类有一些事件,如果你要处理它的一些事件,可以用withevent来声明然后在窗体LOAD事件或你需要的地方先创建一个实例RC = New SpeechLib.SpSharedRecoContext当一个RC被实例化后,系统就会运行语音识别程序.前提是你的系统已经正确安装这个功能.一般默认就已经安装好的.其次提醒一下,WIN7的语音识别比XP的好N倍.从阅读到侦听都好很多.然后就可以在你需要阅读的地方使用RC.Voice.Speak("hello 我", 11)11那里是一些枚举,用来标识系统用前台还是后台或其他方式来阅读文字,简单的来说就是阅读的时候不会卡住你的程序.你可以选其他的枚举来试试作用.以上为阅读部分.如果需要程序听你说话,则需要声明一个侦听类dim RG As SpeechLib.ISpeechRecoGrammar在初始化时将之与上面的RC建立关系,此时则必须要用withevent来声明上面的RC,因为涉及电脑听到你的语音后,会触发一个事件,并将听到的内容传递到该事件.其次,要让系统听到的解析为命令,就必须准备一个XML结构的文件来保存那些固定的命令.如果电脑在XML文件中找不到那些固定命令或同时不属于系统命令,电脑将会将其解释为听写.RG = RC.CreateGrammar '(0)

RG.CmdLoadFromFile("听到.xml", SpeechLib.SpeechLoadOption.SLODynamic)

RG.CmdSetRuleIdState(0, SpeechLib.SpeechRuleState.SGDSActive)然后写一个过程来处理听到的事件Private Sub 听到命令(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechLib.SpeechRecognitionType, ByVal 话语 As SpeechLib.ISpeechRecoResult) Handles RC.Recognition RC.Voice.Speak("我听到了" 话语.PhraseInfo.GetText, 11)End Sub以上为侦听部分.下面列一个XML的例文?xml version="1.0" encoding="gb2312"?

GRAMMAR LANGID="804"

RULE NAME="命令" TOPLEVEL="ACTIVE"

L

P打开播放器

P上我的QQ

P关闭你自己 /L

/RULE

/GRAMMAR要让系统正确地侦听到你说的话,前提你必须运行语音识别程序并让其激活到"正在聆听"状态.并且你必须有一个能正常使用的话筒而且保证话筒已经打开.(废话-_-|||)以上就是用VB.NET语音识别的最基本的一些操作.希望对你有帮助.更深入的内容有兴趣的话可以和我一起研究.

VB.NET中怎么实现 汉字转换拼音呢

建立一个表，每个拼音都跟多个汉字对应。可以通过汉字，找出对应的一个拼音，也可以通过拼音，找出一堆汉字。

如何用vb.net将汉字转换成拼音阿

public string hz2py(string hz) //获得汉字的区位码

{

byte[] sarr = System.Text.Encoding.Default.GetBytes(hz);

int len = sarr.Length;

if (len1)

{

byte[] array = new byte[2];

array = System.Text.Encoding.Default.GetBytes(hz);

int i1 = (short)(array[0] - '\0');

int i2 = (short)(array[1] - '\0');

//unicode解码方式下的汉字码

// array = System.Text.Encoding.Unicode.GetBytes(hz);

// int i1 = (short)(array[0] - '\0');

// int i2 = (short)(array[1] - '\0');

// int t1 = Convert.ToInt32(i1,16);

// int t2 = Convert.ToInt32(i2,16);

int tmp=i1*256+i2;

string getpychar="*";//找不到拼音码的用*补位

if(tmp=45217tmp=45252){getpychar= "A";}

else if(tmp=45253tmp=45760){getpychar= "B";}

else if(tmp=53689tmp=54480){getpychar= "Y";}

else if(tmp=54481tmp=55289){getpychar= "Z";}

return getpychar;

}

else

{

return hz;

}

}

public string transpy(string strhz) //把汉字字符串转换成拼音码

{

string strtemp="";

int strlen=strhz.Length;

for (int i=0;i=strlen-1;i++)

{

strtemp+=hz2py(strhz.Substring(i,1));

}

return strtemp;

}

create table tabpy(id int identity,b_begin varbinary(2),b_end varbinary(2),word varchar(2))

insert tabpy select 0xB0A1, 0xB0C4,'A'

union all select 0xB0C5, 0xB2C0,'B'

union all select 0xB2C1, 0xB4ED,'C'

union all select 0xB4EE, 0xB6E9,'D'

union all select 0xB6EA, 0xB7A1,'E'

union all select 0xB7A2, 0xB8C0,'F'

union all select 0xB8C1, 0xB9FD,'G'

union all select 0xB9FE, 0xBBF6,'H'

union all select 0xBBF7, 0xBFA5,'J'

union all select 0xBFA6, 0xC0AB,'K'

union all select 0xC0AC, 0xC2E7,'L'

union all select 0xC2E8, 0xC4C2,'M'

union all select 0xC4C3, 0xC5B5,'N'

union all select 0xC5B6, 0xC5BD,'O'

union all select 0xC5BE, 0xC6D9,'P'

union all select 0xC6DA, 0xC8BA,'Q'

union all select 0xCEF4, 0xD1B8,'X'

union all select 0xD1B9, 0xD4D0,'Y'

union all select 0xD4D1, 0xD7F9,'Z'

函数：

create function getfirstpy(@a varchar(200))

returns varchar(100)

as

begin

declare @i int,@j int,@result varchar(100)

set @result=''

set @i=len(@a)

set @j=1

while @j=@i

begin

select @result=@result+word from tabpy where cast(substring(@a,@j,1) as varbinary(2)) between b_begin and b_end

set @j=@j+1

end

return @result

end

vb.net不识别word字体怎么办

字体文件直接放到 Fonts文件夹就可以了，新字体需要重启word。你说的不识别字体是指全部显示乱码，还是显示出字体但是不是对应的格式？字体文件有多个格式ttf，ttc，otf等等，有个别格式word是不会识别的，会显示为差不多宋体的样子。但是工具栏里显示的名字是正确的。
