2.VB6中的代码 '*******************************************************************
'<函数:Encode> '作用:将字符串内容转化为16进制数据编码,其逆过程是Decode '参数说明: 'strSource 需要转化的原始字符串 Public Function Encode(strEncode As String) As String Dim i As Long Dim chrTmp$ Dim ByteLower$, ByteUpper$ Dim strReturn$ '存储转换后的编码 For i = 1 To Len(strEncode) chrTmp$ = Mid(strEncode, i, 1) ByteLower$ = Hex$(AscB(MidB$(chrTmp$, 1, 1))) If Len(ByteLower$) = 1 Then ByteLower$ = "0" & ByteLower$ ByteUpper$ = Hex$(AscB(MidB$(chrTmp$, 2, 1))) If Len(ByteUpper$) = 1 Then ByteUpper$ = "0" & ByteUpper$ strReturn$ = strReturn$ & ByteUpper$ & ByteLower$ Next Encode = strReturn$ End Function '</函数:Encode> |
