      I don't often have occasion to use Child GUIs.  I find the multitude of options confusing.
      The example below I made for my own purposes, to have a visual guide to what the various Style and Extended Style options lead to.
      Comments are much appreciated.  This can be extended with many more examples and comments and why certain Styles are to preferred or avoided.  Where certain types of Child GUIs are most suitable etc.
       
      The code is very basic.  It is intended to show GUI Styles, not much else.

      I have the impression that the traditional method for processing responses to a GUI is to assign variables to each GUICreateButton (or Pic) and then use Switch/Case/Endswitch to detect when any Control is clicked.  In the tutorials I've seen about Koda it appears to use this method, too.
      While 1 Global $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Pic2 Call("verizon") Case $Pic3 Call("skype") Case $PicExit Exit EndSwitch WEnd But in a few examples I've seen a script use a different method. The script always includes the following option near the top:
      Opt("GUIOnEventMode", 1) ...and then, later, after creating each Control for the GUI, there's the function, GUICtrlSetOnEvent.  In these cases a very simple While/WEnd loop is used to wait for the user to respond. 
      I happened to employ this second method in a recent script where I used "canned" controls (checkbox and buttons). Later in the same script I used the GuiCreatePic and Switch/Case/EndSwitch method because my GUI was all custom images. (I'm not sure if that's necessary, but it's what I've deduced.) The second GUI failed to respond to any mouse clicks, but eventually I figured out the cause was the GUIOnEvenMode being enabled at the top of the script.
      This is when I realized I don't understand the reasoning behind choosing between these two methods. And I'm having no luck phrasing an appropriate search criterion. Is there an overview somewhere that explains the two methods and -- most importantly -- describes when each is appropriate?

      Hi there 
      I am building a "statistics kiosk" where we will be enumerating through Web Pages, and Excel files, PDF reports and other applications each displaying statistics relevant to our project. I want to overlay some context over each page/screen so that viewers of this "statistics kiosk" have some info about that the data they are looking at is.  I have written a function called OverlayWindow which is supposed to create a transparent window which displays some text. The function SEEMS to work BUT 
      The handle returned from CreateGUI is 0 (despite there being NO error or extended information)  The window is created but not maintained.  In other words it appears but since it is not really maintained it is repainted as other content changes.  The result is that the overlay appears BUT as soon as there is a reason for the underlying windows to repaint the overlay starts to "disappear"  I have extracted the relevant code and created the most simplistic of samples here. 
      #include <FileConstants.au3> #include <WinAPIFiles.au3> #include <GDIPlus.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <WinAPISysWin.au3> Opt("GUIOnEventMode", 1) ; Change to OnEvent mode ; #FUNCTION# ==================================================================================================================== ; Name ..........: OverlayWindow ; Description ...: Throws up a child window with transparent background over current window ; ; Parameters : ; $hwndParent parent hwnd ; $rectToHighlight rect to draw (or if null, skip) ; $rectForText rect for textToWrite ; $textToWrite the text to write ; =============================================================================================================================== Func OverlayWindow($hwndParent, $rectToHighlight, $rectForText, $textToWrite) $style = BitOR($WS_CHILD, $WS_CLIPCHILDREN, $WS_CLIPSIBLINGS) $exstyle = BitOR($WS_EX_TOPMOST, $WS_EX_COMPOSITED, $WS_EX_TRANSPARENT) $hGUI = GUICreate("transparent overlay", -1, -1, -1, -1, $style, $exstyle) ConsoleWrite("**** $hGUI: " & $hGUI & @CRLF) ConsoleWrite("**** @error: " & @error & @CRLF) ConsoleWrite("**** @extended: " & @extended & @CRLF) GUISetOnEvent($GUI_EVENT_CLOSE, "OverlayWindow_Exit") GUISetState(@SW_SHOW, $hGUI) $hGraphics = _GDIPlus_GraphicsCreateFromHWND($hGUI) ConsoleWrite("**** $hGraphics : " & $hGraphics & @CRLF) _GDIPlus_GraphicsSetSmoothingMode($hGraphics, $GDIP_SMOOTHINGMODE_HIGHQUALITY) $hPen = _GDIPlus_PenCreate(0xFFFF0000, 4) ; Red If ($rectToHighlight <> Null) Then _GDIPlus_GraphicsDrawRect($hGraphics, $rectToHighlight[0], $rectToHighlight[1], $rectToHighlight[2], $rectToHighlight[3], $hPen) EndIf _GDIPlus_PenDispose($hPen) $hBrush = _GDIPlus_BrushCreateSolid(0xFFFF0000) ; RED $hFormat = _GDIPlus_StringFormatCreate() $hFamily = _GDIPlus_FontFamilyCreate("Arial") $hFont = _GDIPlus_FontCreate($hFamily, 14, 2) $tLayout = _GDIPlus_RectFCreate($rectForText[0], $rectForText[1], $rectForText[2], $rectForText[3]) $aInfo = _GDIPlus_GraphicsMeasureString($hGraphics, $textToWrite, $hFont, $tLayout, $hFormat) _GDIPlus_GraphicsDrawStringEx($hGraphics, $textToWrite, $hFont, $aInfo[0], $hFormat, $hBrush) _GDIPlus_BrushDispose($hBrush) _GDIPlus_StringFormatDispose($hFormat) _GDIPlus_FontFamilyDispose($hFamily) _GDIPlus_FontDispose($hFont) _GDIPlus_GraphicsDispose($hGraphics) Return $hGUI EndFunc Func OverlayWindow_Exit() ConsoleWrite("* * * Exit event called" & @CRLF) EndFunc Func Handle_Esc() $Done = True EndFunc ;----------------------------------------------------------------- ;Main() _GDIPlus_Startup() Global $Done = False Local $rect = [10, 10, 400, 400] Local $rectForText = [15, 15, 380, 380] $hGUI = OverlayWindow(Null, $rect, $rectForText, "This is a test with long text long text and should automatically wrap long text " & @CRLF & "and " & @CRLF & " handle " & @CRLF & "cariage returns and line feeds") HotKeySet ( "{Esc}", Handle_Esc) While Not $Done Sleep(100) WEnd GUIDelete($hGUI) _GDIPlus_Shutdown () Exit 0 I am assuming the since CreateGUI returns 0 that the  _GDIPlus_GraphicsCreateFromHWND is simply creating a "graphics context" based on the desktop then and not on my window.  And thus - there IS no window (despite no @error nor no @extended data) 
      So I think the issue is in the "styles" of window I am using.
      If I don't use WS_CHILD (for example I use WS_POPUP) then I get a handle back for my window and the lifetime of the window is what i want but it is not transparent as I want. Setting styles on the window to be transparent (either using extended styles, or using WinSetTrans or _WinAPI_SetBkMode) results in my rectangle and string being transparent - not what I want either. 

      Any suggestions?

      any and all help is appreciated
      Thanks!

      Hi
      Maybe I am just being silly, but I don't understand what is supposed to happen here.
      ::/html/functions/GUICreate.htm
      GuiCreate from the Help file has 2 examples.  Specifically, the 2nd example creates a ChildGui.  Or so it says.  I do not see this on screen.
      $hGUI gets created, no problem.
      Local $hChild = GUICreate("ChildGui", 10, 10, 20, 20, $WS_POPUP, BitOR($WS_EX_LAYERED, $WS_EX_MDICHILD), $hGUI) What exactly does this line do? Should I see it on screen?

      I think I am missing something obvious
      I want the "color bar" to stretch from side to side (entire width) of the GUI.  On resize it must expand / contract as necessary.  I guess the answer is easy, but I need a bit of help please?
      $hForm = GUICreate('myColor Picker', 300, 200,-1, -1, $WS_MAXIMIZEBOX + $WS_SYSMENU + $WS_CAPTION) ;color the GUI background ;GUISetBkColor($sColorformFile, $hForm) ; set the gui background color ;Local $mycolorLabel = GUICtrlCreateLabel("",10,10,300,10) ; a blank LABEL color bar Local $mycolorLabel = GUICtrlCreateGraphic( -1,-1,300,10) ; a blank GRAPHIC color bar GUICtrlSetResizing($mycolorLabel, $ws_sizebox);$GUI_DOCKMENUBAR);$GUI_DOCKAUTO) ;$GUI_DOCKBORDERS) GUICtrlSetBkColor($mycolorLabel,$sColorformFile) ; set the color for the label  
      This is an extract from here, by @Yashied
      $hForm = GUICreate('myColor Picker', 300, 200,-1, -1, $WS_MAXIMIZEBOX + $WS_SYSMENU + $WS_CAPTION) ;color the GUI background ;GUISetBkColor($sColorformFile, $hForm) ; set the gui background color ;Local $mycolorLabel = GUICtrlCreateLabel("",10,10,300,10) ; a blank LABEL color bar Local $mycolorLabel = GUICtrlCreateGraphic( -1,-1,300,10) ; a blank GRAPHIC color bar GUICtrlSetResizing($mycolorLabel, $ws_sizebox);$GUI_DOCKMENUBAR);$GUI_DOCKAUTO) ;$GUI_DOCKBORDERS) GUICtrlSetBkColor($mycolorLabel,$sColorformFile) ; set the color for the label Specifically my issue is with that $mycolorLabel
      Thanks, Skysnake
