关于Hex函数.解决方法

关于Hex函数.
用Hex函数时,比如shu(0)=&H0
Hex(shu(0))就是0
怎么样让他变成00?
使用这个方法把Byte数组转换成16进制字串符时,只要是0打头的全省略的.
0E就成E了.怎么弄啊?
Function BinArrayToHex(Bin() As Byte) As String
  Dim iLoop As Integer
  Dim sResult As String
  sResult = " "
  For iLoop = LBound(Bin) To UBound(Bin)
  sResult = sResult + Right("0 " & Hex(Bin(iLoop)), 2) & " "
  Next iLoop
  BinArrayToHex = Trim(sResult)
End Function

Dim A As Long
Dim strTemp As String
A=5
strTemp = Hex(A)
strTemp = String(2-Len(strTemp),"0") & strTemp
Msgbox strTemp

VB下做你需要的这种函数要比你想象中容易的多。HEX不是那么好用的。

VB code

'第一种用法'输出Ascii编码的HEX串（可直接存盘的，显示需要StrConv转换）Text2.Text = StrConv(BytesHEX(tBytes()), vbUnicode) '第二种用法'输出Unicode编码的HEX串（在VB下直接可显示的）'函数输出的是Byte数组，但这里却赋给了字符串。'因为：VB下的Byte数组和字符串之间是可以互相赋值的。Text3.Text = BytesHEX(tBytes(), , True) Function BytesHEX(ByRef pBytes() As Byte, Optional ByVal pLimit As Byte = &H20, Optional ByVal pUnicode As Boolean = False) As Byte()  Dim tSurBytes_Index As Long  Dim tDesBytes() As Byte, tDesBytes_Index As Long, tDesBytes_Length As Long    tDesBytes_Length = UBound(pBytes()) * 3 * ((pUnicode And 1) + 1) + 2 + (pUnicode And 3)    ReDim tDesBytes(tDesBytes_Length)      For tDesBytes_Index = 0 To tDesBytes_Length Step (3 + (pUnicode And 3))    tDesBytes(tDesBytes_Index) = HexEnCode(pBytes(tSurBytes_Index) \ 16)    tDesBytes(tDesBytes_Index + 1 + (pUnicode And 1)) = HexEnCode(pBytes(tSurBytes_Index) Mod 16)    tDesBytes(tDesBytes_Index + 2 + (pUnicode And 2)) = pLimit    tSurBytes_Index = tSurBytes_Index + 1  Next    BytesHEX = tDesBytes()End FunctionFunction HexEnCode(pHEX As Byte) As Byte  '根据0～15的Byte数值输出0～F的Ascii码  '这行函数的意思是：HexEnCode = 48 + pHEX；如果pHEX>9，那么HexEnCode再加7。  HexEnCode = 48 + pHEX + ((pHEX > 9) And 7)End Function

right("0" & Hex(shu(0)),2)
