鉴于光标在某个TextRange tr内，我想要一个Sub，它将tr作为输入参数并选择(或返回)一个从包含tr.start的当前行的开头开始，到"."或"："的下一个实例结束的TextRange)。理想情况下，这将适用于任意TextRange或当前选择(ActiveWindow.Selection.TextRange)。注意：可能是那个tr.Length = 0(实际上没有选择)。
我已经通过实现文本框架中所有段落的循环来查找包含光标的段落，然后通过该段落中的行来查找包含光标的行来回答这个问题。然后选择行中的文本，从第一个字符开始，一直延伸到"."、"："或行尾的第一个字符。然后将"样式"应用于所选文本。该代码如下(代码后面有一些注释)。
我仍然希望有一个不需要搜索的更优雅的解决方案。
Option Explicit
Sub StyleRunInApply()
' Apply the run-in style to current selection (assumed to be a text range). If
' no characters are selected, apply from the beginning of the current line to
' the first of "." or ":" or the end of the current line.
'
' The "run-in style" is defined to be bold with Accent2 color of the current
' master theme.
Dim iLine As Long
Dim lenth As Long
Dim line As TextRange
Dim pgf As TextRange
Dim tr As TextRange
Dim thme As OfficeTheme
Set tr = ActiveWindow.Selection.TextRange
If tr.Length = 0 Then
' Loop through pgfs in parent text frame to find our line--
' the first pgf that ends at or beyond the cursor.
For Each pgf In tr.Parent.TextRange.Paragraphs
If pgf.Start + pgf.Length > tr.Start Or _
pgf.Start + pgf.Length > tr.Parent.TextRange.Length Then GoTo L_foundPgf
Next pgf ' (If fall through, pgf will be the final pgf in the frame.)
L_foundPgf:
' Find last line in pgf that starts before the cursor.
While iLine < pgf.Lines.Count And pgf.Lines(iLine + 1).Start < tr.Start
iLine = iLine + 1
Wend
Set line = pgf.Lines(iLine)
' Now look in the line for a ":" or "." and reset tr from the start of
' the line up to and including the first of a ":" or "." or the end of
' line.
lenth = line.Length
If Not line.Find(":") Is Nothing Then
lenth = line.Find(":").Start - line.Start + 1
ElseIf Not line.Find(".") Is Nothing Then
If line.Find(".").Start - line.Start + 1 < lenth Then
lenth = line.Find(".").Start - line.Start + 1
End If
End If
Set tr = line.Characters(1, lenth)
End If
' Set the finally selected text to the style!
Set thme = ActivePresentation.SlideMaster.Theme
tr.Font.Color = thme.ThemeColorScheme(msoThemeAccent2)
tr.Font.Bold = True
End Sub 'StyleRunInApply
关于代码的三条评论：
- 欢迎改进。
- 设置要选择的文本的结束位置而不是长度的变体在可理解性、大小和优雅方面似乎大致相同。
- 为GoTo辩护：我仅将其用作"缺失"语言功能的替代品的一部分，在这种情况下，
Exit For，然后，对于此类退出，仅紧跟Then，这就是没有块跟随Then的原因。
