static extern bool PathCompactPath(IntPtr hDC, [In, Out] StringBuilder pszPath, int dx);

VB Signature:

Notes:

If you do not have a HDC available, take a look at PathCompactPathEx

Tips & Tricks:

Please add some!

Sample Code:

public partial class frmMain : Form

{

    [DllImport("shlwapi.dll", CharSet = CharSet.Auto)]
    static extern bool PathCompactPath(IntPtr hDC, [In, Out] StringBuilder pszPath, int dx);

    public string PathCompactPath(string path, int pixel)
    {
    Graphics gc = this.CreateGraphics();
    StringBuilder strBuffer = new StringBuilder(path);
    PathCompactPath((IntPtr)gc.GetHdc(), strBuffer, pixel);
    return strBuffer.ToString();
    }

}
