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点虐 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点虐 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)
