Q2: VB中16进制与10进制相互转化，该怎么处理
10进制转16进制的话可以使用HEX()函数，16进制转10进制没有现成函数，可以使用如下代码实现：
' 用途：将十六进制转化为十进制
' 输入：Hex(十六进制数)
' 输入数据类型：String
' 输出：HEX_to_DEC(十进制数)
' 输出数据类型：Long
' 输入的最大数为7FFFFFFF,输出的最大数为2147483647
Public Function HEX_to_DEC(ByVal Hex As String) As Long
Dim i As Long
Dim B As Long
Hex = UCase(Hex)
For i = 1 To Len(Hex)
Select Case Mid(Hex, Len(Hex) - i + 1, 1)
Case "0": B = B + 16 ^ (i - 1) * 0
Case "1": B = B + 16 ^ (i - 1) * 1
Case "2": B = B + 16 ^ (i - 1) * 2
Case "3": B = B + 16 ^ (i - 1) * 3
Case "4": B = B + 16 ^ (i - 1) * 4
Case "5": B = B + 16 ^ (i - 1) * 5
Case "6": B = B + 16 ^ (i - 1) * 6
Case "7": B = B + 16 ^ (i - 1) * 7
Case "8": B = B + 16 ^ (i - 1) * 8
Case "9": B = B + 16 ^ (i - 1) * 9
Case "A": B = B + 16 ^ (i - 1) * 10
Case "B": B = B + 16 ^ (i - 1) * 11
Case "C": B = B + 16 ^ (i - 1) * 12
Case "D": B = B + 16 ^ (i - 1) * 13
Case "E": B = B + 16 ^ (i - 1) * 14
Case "F": B = B + 16 ^ (i - 1) * 15
End Select
Next i
HEX_to_DEC = B
End Function

Q3: VB.NET，八/十六进制转十进制的函数
VB.Net自带函数：
十进制转八进制：Oct(num)
十六进制转八进制：oct("H" num)
十进制转十六进制：hex(num)
八进制转十六进制：hex("O" num)
十六进制转换为十进制：CLng("H" num)

Q5: 用VB.NET将二进制数转换为十进制数
.NET 程序写成vb.net10进制转你这样也算厉害vb.net10进制转了vb.net10进制转，好好看看下面vb.net10进制转的代码
Sub Main()
Console.WriteLine("请输入一个二进制数")
Console.WriteLine(bin2int(Console.ReadLine()))
Console.ReadKey()
End Sub
Function bin2int(ByVal bin As String) As Integer
Dim i As Long
For i = 1 To bin.Length
bin2int = bin2int * 2 + Val(Mid(bin, i, 1))
Next i
End Function
