Local $edtpst_db = "C:\Users\User\AppData\Local\PTMW\edtpst_db.ini"
Local $hGUI5 = GUICreate("", 650, 550)
Local $idListView = GUICtrlCreateListView("", 5, 5, 640, 500, BitOR($LVS_SHOWSELALWAYS, $LVS_NOSORTHEADER, $LVS_REPORT))
Local $hCMenu_edtpst = GUICtrlCreateContextMenu($idListView) 
Local $edtpst_edt = GUICtrlCreateMenuItem("edit post", $hCMenu_edtpst, 1)
;=============================================================================
_GUICtrlListView_SetExtendedListViewStyle($idListView, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_GRIDLINES, $LVS_EX_DOUBLEBUFFER))

For $i = 1 To UBound($aArray)-1
    $GDIpBmpLarge = _GDIPlus_BitmapCreateFromMemory(Binary(FileRead($aArray[$i]))) ;GDI+ image!
    $GDIpBmpResized = _GDIPlus_ImageResize($GDIpBmpLarge, 128, 128) ;GDI+ image

AlienStar,

I imagine it is because you have added items using the _GUICtrlListView UDF functions and not the native GUICtrlCreateListViewItem function. Thus there is no ControlID for GUICtrlRead to use. Try using the native function to add the elements to your ListView and you should be able to read them.

Open spoiler to see my UDFs:

ChooseFileFolder ---- Single and multiple selections from specified path treeview listing
Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
