C# Signature:
[DllImport("shlwapi.dll", CharSet=CharSet.Auto)]
static extern bool PathAppend([In, Out] StringBuilder pszPath, string pszMore);
VB.NET Signature
''' <summary>
''' Appends one path to the end of another.
''' </summary>
''' <param name="pszPath">A pointer to a null-terminated string to which the path specified in pszMore is appended.</param>
''' <param name="pszMore">A pointer to a null-terminated string of maximum length MAX_PATH that contains the path to be appended.</param>
''' <returns>Returns TRUE if successful, or FALSE otherwise.</returns>
''' <remarks>
''' This function automatically inserts a backslash between the two strings,
''' if one is not already present.
''' The path supplied in pszPath cannot begin with "..\\" or ".\\" to produce a relative path
''' string. If present, those periods are stripped from the output string.
''' For example, appending "path3" to "..\\path1\\path2" results in an output of "\path1\path2\path3" rather than "..\path1\path2\path3".
''' </remarks>

Notes:
This is similar, but not identical, to PathCombine and Path.Combine. For example, appending "C:\foo" with "\bar" yields "C:\foo\bar" rather than "C:\bar" or "\bar", respectively.
