• excel 汉字转换成拼音

    • 1、打开EXCEL
      2、按 ALT+F11 ,点击插入-插入模块,在右面窗口中粘贴下面代码,直接关闭窗口
      3、输入公式=hztopy(A1),填充所有单元格
      4、选中所有缩写,复制-选择性粘贴-数值(因为是自定义函数,只有在当前文件中可以显示结果,其他电脑因没有公式而显示错误)

      下面这个函数是将汉字转换了简拼,只取首字母
      Function hztopy(hzpy As String) As String
      Dim hzstring As String, pystring As String
      Dim hzpysum As Integer, hzi As Integer, hzpyhex As Integer
      hzstring = Trim(hzpy)
      hzpysum = Len(Trim(hzstring))
      pystring = ""
      For hzi = 1 To hzpysum
      hzpyhex = "&H" + Hex(Asc(Mid(hzstring, hzi, 1)))
      Select Case hzpyhex
      Case &HB0A1 To &HB0C4: pystring = pystring + "A"
      Case &HB0C5 To &HB2C0: pystring = pystring + "B"
      Case &HB2C1 To &HB4ED: pystring = pystring + "C"
      Case &HB4EE To &HB6E9: pystring = pystring + "D"
      Case &HB6EA To &HB7A1: pystring = pystring + "E"
      Case &HB7A2 To &HB8C0: pystring = pystring + "F"
      Case &HB8C1 To &HB9FD: pystring = pystring + "G"
      Case &HB9FE To &HBBF6: pystring = pystring + "H"
      Case &HBBF7 To &HBFA5: pystring = pystring + "J"
      Case &HBFA6 To &HC0AB: pystring = pystring + "K"
      Case &HC0AC To &HC2E7: pystring = pystring + "L"
      Case &HC2E8 To &HC4C2: pystring = pystring + "M"
      Case &HC4C3 To &HC5B5: pystring = pystring + "N"
      Case &HC5B6 To &HC5BD: pystring = pystring + "O"
      Case &HC5BE To &HC6D9: pystring = pystring + "P"
      Case &HC6DA To &HC8BA: pystring = pystring + "Q"
      Case &HC8BB To &HC8F5: pystring = pystring + "R"
      Case &HC8F6 To &HCBF9: pystring = pystring + "S"
      Case &HCBFA To &HCDD9: pystring = pystring + "T"
      Case &HEDC5: pystring = pystring + "T"
      Case &HCDDA To &HCEF3: pystring = pystring + "W"
      Case &HCEF4 To &HD1B8: pystring = pystring + "X"
      Case &HD1B9 To &HD4D0: pystring = pystring + "Y"
      Case &HD4D1 To &HD7F9: pystring = pystring + "Z"
      Case Else
      pystring = pystring + Mid(hzstring, hzi, 1)
      End Select
      Next
      hztopy = pystring
      End Function

    • 如何将Bitmap位图与base64字符串相互转换

    • 先引用delphi自带的单元
      uses EncdDecd;

      然后就可以使用下面二个函数了:

      ///将Bitmap位图转化为base64字符串
      function BitmapToString(img:TBitmap):string ;
      var
      ms:TMemoryStream;
      ss:TStringStream;
      s:string;
      begin

      ms := TMemoryStream.Create;
      img.SaveToStream(ms);
      ss := TStringStream.Create('');
      ms.Position:=0;
      EncodeStream(ms,ss);//将内存流编码为base64字符流
      s:=ss.DataString;
      ms.Free;
      ss.Free;
      result:=s; 

      end;

      ///将base64字符串转化为Bitmap位图
      function StringToBitmap(imgStr:string):TBitmap;
      var ss:TStringStream;

      ms:TMemoryStream;
      bitmap:TBitmap;

      begin

      ss := TStringStream.Create(imgStr);
      ms := TMemoryStream.Create;
      DecodeStream(ss,ms);//将base64字符流还原为内存流
      ms.Position:=0;
      bitmap := TBitmap.Create;
      bitmap.LoadFromStream(ms);
      ss.Free;
      ms.Free;
      result :=bitmap;

      end;
