Question

我想从powerpoint中获取一些文本以用于其他软件。但是该软件仅支持ASCII字符（无扩展ASCII）。如何删除不是ASCII的字符？有什么方法可以在VBA中实现吗？

Answer 1

在我们的Access VBA代码中，我们使用2个函数将Extended Latin转换为ASCII，希望它适用于VBA Power Point：

予。 chrRemoveAccents（）从字符

中删除重音

II。 strRemoveAccents（）使用chrRemoveAccents（）从字符串中删除重音。

Function chrRemoveAccents(ByVal c1)
  Dim iCode As Long
  iCode = AscW(c1)
'
  Select Case iCode
'
' À = 192; Á = 193; Â = 194; Ã = 195; Ä = 196; Å = 197;
'
    Case 192 To 197
      chrRemoveAccents = "A"

' Æ = 198;

    Case 198
      chrRemoveAccents = "AE"

    Case 217 To 220
      chrRemoveAccents = "U"
'

    Case 221, 376
      chrRemoveAccents = "Y"

    Case 338
      chrRemoveAccents = "OE"
'
' Š = 352;

    Case 352
      chrRemoveAccents = "S"
'
'
' à=224, á = 225; â = 226; ã = 227; ä = 228; å = 229;

    Case 224 To 229
      chrRemoveAccents = "a"

    Case 231
      chrRemoveAccents = "c"
'
' è = 232; é = 233; ê = 234; ë = 235;
'
    Case 232 To 235
      chrRemoveAccents = "e"
'
' ì = 236; í = 237; î = 238; ï = 239;
'
    Case 236 To 239
      chrRemoveAccents = "i"
'
' ð = 240;
'
    Case 240
      chrRemoveAccents = "d"
'
' ñ = 241;
'
    Case 241
      chrRemoveAccents = "n"
'
' ò = 242; ó = 243; ô = 244; õ = 245; ö = 246;
'
    Case 242 To 246
      chrRemoveAccents = "o"

    Case 249 To 252
      chrRemoveAccents = "u"

    Case 253, 255
      chrRemoveAccents = "y"
'
' œ = 339;
'
    Case 339
      chrRemoveAccents = "oe"
'
' š = 353;
'
    Case 353
      chrRemoveAccents = "s"
'
    Case Else
      chrRemoveAccents = c1
  End Select
End Function

Function strRemoveAccents(ByVal varIn)
  Dim i As Long, lng As Long
'
  Dim str1 As String
  str1 = ""
'
  If (Not IsNull(varIn)) Then
'
    lng = Len(varIn)
'
    For i = 1 To lng
      str1 = str1 & chrRemoveAccents(Mid(varIn, i, 1))
    Next
'
  End If
'
  strRemoveAccents = str1
End Function

呼叫：

strAscii = strRemoveAccents("écolière")

给出：

strAscii = "ecoliere"

仅允许ascii字符VBA
