Reverse a String
This is a string handling function that that reverse a given string. For example, Good Morning becomes gninroM dooG.
The code reads a string into an array, which is no surprise. We could use a temporary "working" string, or an array to achieve the goal. What is a bit different here is that as the string is read in from the beginning, the values are placed at the back of the array.
The last step is the bring the array back out to a usable string, and return it to the caller.
Private Function ReverseString(ByRef StringToReverse As String) As String
Dim lngIndex As Long
Dim ByteArray() As Byte
Dim tmpByte As Byte
Dim lngMax As Long
ByteArray = StrConv(StringToReverse, vbFromUnicode)
lngMax = Len(StringToReverse) - 1
For lngIndex = 0 To lngMax \ 2
tmpByte = ByteArray(lngIndex)
ByteArray(lngIndex) = ByteArray(lngMax - lngIndex)
ByteArray(lngMax - lngIndex) = tmpByte
Next
ReverseString = StrConv(ByteArray, vbUnicode)
End Function
