Examples

Sub ChangeLeftExample()  
   ' Open a document before running this example.  
   Dim objSel As TextSelection = DTE.ActiveDocument.Selection  
   objSel.StartOfDocument(True)  
   objSel.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstText)  
   objSel.CharRight(True, 4)  
   objSel.ChangeCase(vsCaseOptions.vsCaseOptionsUppercase)  
   MsgBox("Turned text uppercase.")  
   objSel.CharLeft(False, 1)  
   objSel.ChangeCase(vsCaseOptions.vsCaseOptionsLowercase)  
   MsgBox("Turned text lowercase.")  
End Sub

Remarks

If Extend is True, then the active end of the text selection is moved left Count characters. Otherwise, the text selection is collapsed and positioned Count characters to the left of the active end.

If the beginning of the document is encountered before Count characters, then the position is left at the beginning of the document. If the active end is at the beginning of a line, then CharLeft leaves it at the end of the previous line. That is, all newline sequences are treated as a single character.

If Count is negative, then CharLeft acts like the CharRight.
