Case switching

Posted by David Little on November 29th, 1998
I have a bad habit of hitting the CapsLock key and when I type code, the shift key does the opposite, so instead of typing m_bSomeVariable, I will look up and see that I have typed M_BsOMEvARIABLE. DevStudio provides <Shift><U> and <Ctrl><Shift><U> to lower and upper case a selection, but nothing provides a "SwapCase" function. The following macro will do the swap. I assigned it to <Alt><U>, but that is entirely up to you ....


Sub SwapCase()
	' DESCRIPTION: Macro to swap the case of selected words.

	str = ActiveDocument.Selection.Text
	str1 = ""
	i = 1
	Do While (i < Len(str)+1)
		If (Mid(str, i, 1) = LCase(Mid(str, i, 1))) Then
			str1 = str1 + UCase(Mid(str, i, 1))
		Else
		str1 = str1 + LCase(Mid(str, i, 1))
		End If
		i = i + 1
	Loop
	ActiveDocument.Selection.Text = str1
End Sub

  • Alternate Macro

    Sub SwapCase()

    ' DESCRIPTION: Swap the case of the current selection.


      strText = ActiveDocument.Selection.Text

      

      For i = 1 To Len(strText)

        

        ch = Asc(Mid(strText, i, 1))

        

        If (ch >= 65 And ch <= 90) Or (ch >= 97 And ch <= 122) Then ch = ch Xor 32

        

        strNew = strNew + Chr(ch)


      Next


      ActiveDocument.Selection.Text = strNew


    End Sub

    This macro is a very handy tool for me. Thanks David!

    The main problem is not about caps lock's wrong position on the key board, rather it is the programmer's attention on his work.

    Very good solution to a very annoying problem.
