_StringCompact() - Compact a string to a certain number of characters left and right.

I found the code I used for this. There are magic numbers in there, but they are documented and the constants can be put back if you wish. Don't get mad at me - this is exactly the method I used. 

Styles - $ES_AUTOHSCROLL, $ES_READONLY

Extended Style - $WS_EX_TRANSPARENT

Global $sFilePath = "C:\Documents and Settings\User\Desktop\one_two_three_four_five_six_seven_eight.txt"
Global $sNewPath = "C:\Documents and Settings\User\Desktop\New Folder\1345678.txt"

_ExampleGUI($sFilePath, $sNewPath)

Func _ExampleGUI($sFilePath, $sNewPath)
    Local $sText, $iGUIHeight, $iGUIWidth
    $sText = "Truncation Alternative"
    $iGUIWidth = 256
    $iGUIHeight = 148

    Local $hGUI = GUICreate($sText, $iGUIWidth, $iGUIHeight, Default, Default, Default, Default)
    GUISetBkColor(0xF0EEE0, $hGUI)

    GUICtrlCreateLabel("Source:", 10, 10, 50, 20) ; Source File
    GUICtrlSetFont(-1, 9, 600)

    ; The text may be too long to fit on a label, but an Input control can be made to look like a label.
    GUICtrlCreateInput(StringRegExpReplace($sFilePath, "(.*\\)+", ""), 63, 10, 183, 20, BitOR(0x80, 0x800), 0x20) ; BitOR($ES_AUTOHSCROLL, $ES_READONLY), $WS_EX_TRANSPARENT)
    GUICtrlSetFont(-1, 9)
    GUICtrlSetBkColor(-1, 0xF0EEE0)

    GUICtrlCreateLabel("Folder:", 10, 36, 50, 20) ; Output Folder
    GUICtrlSetFont(-1, 9, 600)

    Local $hNewFolder = GUICtrlCreateInput(StringRegExpReplace($sNewPath, "(.+\\)(.+)(\\)(.+\z)", "$2"), 63, 36, 151, 20, BitOR(0x80, 0x800), 0x20) ; BitOR($ES_AUTOHSCROLL, $ES_READONLY), $WS_EX_TRANSPARENT)
    GUICtrlSetFont(-1, 9)
    GUICtrlSetBkColor(-1, 0xF0EEE0)

    GUISetState()

    While 1
        $msg = GUIGetMsg()
        If $msg = -3 Then ExitLoop ; $GUI_EVENT_CLOSE
    WEnd
EndFunc

I don't care anymore. Thanks for posting.

Having the option to avoid truncation without making a mess of your design is nice. Both solutions have merit.

The code was written a while ago using an older version.
