怎样读取汉字的首子母？
返回给定字符串的首字母
Function IndexCode(ByVal IndexTxt As String) As String
Dim i As Integer
For i = 1 To IndexTxt.Length
IndexCode = IndexCode & GetOneIndex(Mid(IndexTxt, i, 1))
Next
End Function
得到单个字符的首字母
Private Function GetOneIndex(ByVal OneIndexTxt As String) As String
If Asc(OneIndexTxt) >= 0 And Asc(OneIndexTxt) < 256 Then
GetOneIndex = OneIndexTxt
Else
GetOneIndex = GetX(CInt(Format((Asc(OneIndexTxt) + 65536) \ 256 - 160, "00") & Format((Asc(OneIndexTxt) + 65536) Mod 256 - 160, "00")))
End If
End Function
根据区位得到首字母
Private Function GetX(ByVal GBCode As Integer) As String
判断一级汉字
If GBCode >= 1601 And GBCode < 1637 Then GetX = "A"
If GBCode >= 1637 And GBCode < 1833 Then GetX = "B"
If GBCode >= 1833 And GBCode < 2078 Then GetX = "C"
If GBCode >= 2078 And GBCode < 2274 Then GetX = "D"
If GBCode >= 2274 And GBCode < 2302 Then GetX = "E"
If GBCode >= 2302 And GBCode < 2433 Then GetX = "F"
If GBCode >= 2433 And GBCode < 2594 Then GetX = "G"
If GBCode >= 2594 And GBCode < 2787 Then GetX = "H"
If GBCode >= 2787 And GBCode < 3106 Then GetX = "J"
If GBCode >= 3106 And GBCode < 3212 Then GetX = "K"
If GBCode >= 3212 And GBCode < 3472 Then GetX = "L"
If GBCode >= 3472 And GBCode < 3635 Then GetX = "M"
If GBCode >= 3635 And GBCode < 3722 Then GetX = "N"
If GBCode >= 3722 And GBCode < 3730 Then GetX = "O"
If GBCode >= 3730 And GBCode < 3858 Then GetX = "P"
If GBCode >= 3858 And GBCode < 4027 Then GetX = "Q"
If GBCode >= 4027 And GBCode < 4086 Then GetX = "R"
If GBCode >= 4086 And GBCode < 4390 Then GetX = "S"
If GBCode >= 4390 And GBCode < 4558 Then GetX = "T"
If GBCode >= 4558 And GBCode < 4684 Then GetX = "W"
If GBCode >= 4684 And GBCode < 4925 Then GetX = "X"
If GBCode >= 4925 And GBCode < 5249 Then GetX = "Y"
If GBCode >= 5249 And GBCode <= 5589 Then GetX = "Z"
判断二级汉字
If GBCode >= 5601 And GBCode <= 8794 Then
