vb.net写16进制 vb发送16进制

vb.net 中2、8、10、16进制转换代码怎么写

Option Explicit

Dim Jz As Integer, K As Boolean

Private Sub Command1_Click()

Pic.Cls

If K Then Jz = Val(Qtjz.Text)

If Pd(Text1.Text, Jz) Then Pic.Print "选择vb.net写16进制的进制与数不符": Exit Sub

If Jz = 0 Then Pic.Print "请先输入进制" Else Pic.Print Zh(Text1.Text, Jz)

End Sub

Private Sub Command2_Click()

End

End Sub

Private Sub Frame1_DragDrop(Source As Control, X As Single, Y As Single)

End Sub

Private Sub Option1_Click(Index As Integer)

K = False

Select Case Index

Case 0

Jz = 2

Case 1

Jz = 8

Case 2

Jz = 10

Case 3

Jz = 16

Case 4

K = True

Qtjz.Text = ""

Qtjz.SetFocus

End Select

If Index 4 Then Command1.SetFocus

End Sub

Private Sub Qtjz_Click()

Qtjz.Text = ""

End Sub

Private Sub Text1_Click()

Text1.Text = ""

End Sub

Private Function Zh(a As String, b As Integer) As Integer

Dim c As String, i, d As Integer

a = LCase(a)

For i = 1 To Len(a)

c = Mid(a, Len(a) + 1 - i, 1)

If Asc(c) 96 Then d = Asc(c) - 87 Else d = Val(c)

Zh = Zh + d * b ^ (i - 1)

Next i

End Function

Private Function Pd(a As String, b As Integer) As Boolean

Dim c As String, i, d As Integer

Pd = False

For i = 1 To Len(a)

c = Mid(a, Len(a) + 1 - i, 1)

If Asc(c) 96 Then d = Asc(c) - 87 Else d = Val(c)

If d b - 1 Then Pd = True: Exit Function

Next i

End Function

如何用vb.net向串口发送十六位进制数据

下面代码就是将文本框中以一个空格隔开的十六进制转为字节的代码，文本框中数字格式为：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 如何将十六进制字符串转换为十六进制变量

numHex =Integer.Parse(strHex, Globalization.NumberStyles.AllowHexSpecifier)

或

numHex = Integer. Parse("H" strHex)

vb.net里怎么声明一个十六进制的数

在内存中没有所谓得16进制或者其他进制，数就是数，什么进制是人自己理解的，而不是计算机。你所谓的16进制大概时你输入的字符序列，你自己需要把这个字符序列转换为数。

也许你要的是

Dim hex As Integer = H50 '这种定义
