VB.NET，八/十六進制轉(zhuǎn)十進制的函數(shù)，怎么轉(zhuǎn)?

'此函數(shù)用于十進制到二進制

Private Function Bin(Number As Long) As Long

Dim Div_value As String

Do

Div_value = (Number Mod 2) Div_value

Number = Int(Number / 2)

Loop Until Number 2

Bin = Number Div_value

End Function

'此函數(shù)用于二進制到十進制

Private Function value_Bin(Number As Long) As Long

Dim Temp_value As Long, Cyc As Long

For Cyc = 0 To Len(Str(Number))

If Cyc = Len(Str(Number)) Then

value_Bin = Temp_value + Val(Mid(Str(Number), Cyc, 1))

Exit For

End If

If Cyc 0 Then Temp_value = (Temp_value + Val(Mid(Str(Number), Cyc, 1))) * 2

Next Cyc

End Function

'====寫入以上函數(shù)后轉(zhuǎn)值操作：

'十進制到十六進制：Hex(十進制數(shù)值)

'十進制到八進制：Oct(十進制數(shù)值)

'十進制到二進制：Bin(十進制數(shù)值)

'二進制到十進制：value_Bin(二進制數(shù)值)

'八進制到十進制：Val("O" 八進制數(shù)值)

'十六進制到十進制：Val("H" 十六進制數(shù)值)

比如

msgbox DEC_to_BIN(10)

就會返回一個10轉(zhuǎn)換為十進制后的結(jié)果

或者簡單點就用

VB自帶函數(shù)：

十進制轉(zhuǎn)八進制：Oct(num)

十六進制轉(zhuǎn)八進制：oct("H" num)

十進制轉(zhuǎn)十六進制：hex(num)

八進制轉(zhuǎn)十六進制：hex("O" num)

十六進制轉(zhuǎn)換為十進制

Dim str As String

str = Text2.Text

Text10.Text = CLng("H" str)

vb.net 把十進制數(shù)轉(zhuǎn)成十六進制數(shù)的函數(shù)有哪些？

Private?Sub?Form1_Load(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?MyBase.Load

MsgBox(DEC_to_HEX(255))

End?Sub

Public?Function?DEC_to_HEX(ByVal?Dec?As?Long)?As?String

Dim?a?As?String

DEC_to_HEX?=?""

Do?While?Dec??0

a?=?CStr(Dec?Mod?16)

Select?Case?a

Case?"10"?:?a?=?"A"

Case?"11"?:?a?=?"B"

Case?"12"?:?a?=?"C"

Case?"13"?:?a?=?"D"

Case?"14"?:?a?=?"E"

Case?"15"?:?a?=?"F"

End?Select

DEC_to_HEX?=?a??DEC_to_HEX

Dec?=?Dec?\?16

Loop

End?Function

如何用vb.net向串口發(fā)送十六位進制數(shù)據(jù)

下面代碼就是將文本框中以一個空格隔開的十六進制轉(zhuǎn)為字節(jié)的代碼，文本框中數(shù)字格式為：01 02 03

Dim TestArray() As String = Split(TextBox1.Text)

Dim hexBytes() As Byte

ReDim hexBytes(TestArray.Length - 1)

Dim i As Integer

For i = 0 To TestArray.Length - 1

hexBytes(i) = Val("h" TestArray(i))

Next

SerialPort.Write(hexBytes, 0, hexBytes.Length)

vb.net &H轉(zhuǎn)換問題

Dim s As String = "h" Hex(Asc(Val(InputBox("輸入數(shù)值", "提示", 1))))

MsgBox(s)

如何用VB.NET將單精度16進制轉(zhuǎn)換成浮點數(shù)

#讀取上次檢查到的行數(shù)

last_line=`cat ./mailinfo`

echo "上次行數(shù)："$last_line

#算出本次alert日志的行數(shù)

current_line=`wc -l $alert_log|awk '{print $1}'`

echo "本次行數(shù)："$current_line

#取上次行數(shù)和本次行數(shù)之間的alert日志內(nèi)容，然后把ORA錯誤及上下三行放到mailinfo中
