Prevent GUI appearing on top of full-screen app (like RDP)

8 posts in this topic

#1 ·  Posted (edited)

Hi,

I've searched but can only find posts from people with the opposite problem (asking how to get their GUI to display on top of a full-screen app, usually a game.

I've created a toolbar which I use in a work environment, creating the GUI with the following styles;

$hwnd = GUICreate($title, $toolbarWidth, $height, $left, $top, $WS_POPUPWINDOW, BitOR($WS_EX_TOOLWINDOW, $WS_EX_TOPMOST))
 
I want it to have a TOPMOST style as it's supposed to behave like the Windows taskbar (which it does in all but one scenario).
 
If I start a full-screen RDP session, I can still see my toolbar and have to close it.  Is there a way I can make it appear on top of all windows *except* full-screen apps (in the same way the taskbar allows full-screen apps on top of it)?
 
Thanks in advance.
 
Val.

I would just check if the active window fills the screen, and if it does, turn off on top of your toolbar.

I would do it like so: >link to topic.

Or you can get the handle to your toolbar and check it with WinGetState(), this will tell you if the application is maximized as well.

Thanks for your replies.  I could indeed introduce a loop to check for an active full-screen window, but I was hoping for a style constant (or combination thereof) which might do the trick and order it behind full-screen windows natively, much like the taskbar.

I'm not concerned about maximized windows as I'm using a combination of DllStructCreate and DllCall to leverage the SHAppBarMessage shell function and register my toolbar as an appbar, so its position and dimensions are respected in much the same way as the taskbar, and windows maximize up to it, not over it.

The only issue I've yet to overcome is full-screen windows.  Your suggestion is valid, I'm just hoping for something a little more elegant.

What happens if you do:

WinSetOnTop($hwnd, "", 1)

Edit:

Sorry, I misread your request.  Indeed you could use WinSetOnTop() more than likely, but you'd have to verify (In a loop) what to look for.  There's no "conditional" constant you can put in the creation of a GUI.

Would that not just set my toolbar to the topmost window, in the same way the extended styles are on creation?

EDIT: Just to test the theory, I removed the $WS_EX_TOPMOST extended-style from my GUICreate line and added your line below.  The toolbar remains on top of all windows, including full-screen windows, so the behaviour is the same.

Rgds,

Val.

Indeed it would, like I said, I misread your initial request.  But like I said, without a checking the state of the active window, you cannot manage your issue correctly.

I've no idea if this will work or not, I do not have a full screen window to popup nor do I feel the urge to create one.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $ghWnd = GUICreate("", 100, 30, 0, 0, $WS_POPUPWINDOW, $WS_EX_TOOLWINDOW)
WinSetState($ghWnd, "", 1)
GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
    _myWinOnTopIfFullSizeWin($ghWnd, False)
WEnd


Func _myWinOnTopIfFullSizeWin($hWndOnTop, $bOnTop = True)

    Local Const $iWidth = @DesktopWidth
    Local Const $iHeight = @DesktopHeight

    Local $hActive = WinActive("[ACTIVE]")
    If Not $hActive Then Return $hActive

    Local $aPos = WinGetPos($hActive)
    If Not IsArray($aPos) Then
        Return SetError(1, 0, 0)
    EndIf

    Local $iOnTop = 0

    If $aPos[0] <= 0 And $aPos[1] <= 0 And _
        $aPos[2] >= $iWidth And $aPos[3] >= $iHeight Then
        ; we have a full screen window
        $iOnTop = (($bOnTop) ? 1 : 0)
        WinSetState($hWndOnTop, "", $iOnTop)
        Return $hActive
    EndIf

    ; do the opposite if we're here of $bOnTop
    $iOnTop = (($bOnTop) ? 0 : 1)
    WinSetOnTop($hWndOnTop, "", $iOnTop)

    Return $hActive
EndFunc

      I've made a form in Koda where I make a list of 3 user definable elements that I want to be able to replicate with a button press so a user can add data that can be used as part of the program.

Since the fields can number over 30 locations in some examples I am thinking about having these items in a scrolling window. What is the best way to do this and can auto it add a variable while running by pressing a button?

      Hi,
      I made a small blunder with my code. I created the GUI under 1920x1080 resolution however, my user is configured to ONLY 1080x720 and cannot go any further than that.
      What do you guys think is the best way to correct this one? Resolution mathematics is something that came to mind however I do not have access to his PC to check  from time to time if  my estimation is correct and the resolution on my PC doesn't go down to 1080x720.
      Please help.

      A fullscreen console with custom commands!

      Introduction:
      Hi everyone!
      This funny project started as a question in the help section:
      https://www.autoitscript.com/forum/topic/174404-edit-detect-key-before-updating-content/
      I'd like to share this script with everyone that is interested. 
       
      Why would I want it?
      You like the old style fullscreen console (like in the old day's), You can add custom commands, You can customize the font a lot more compared to cmd.exe, You can share ideas or add tweaks to the script.  
      Still to do:
      Write a simple custom programming language to implement this tool. Writing a little help file / pdf to describe my little programming language. Add little sound effects like a beep if there is a syntax error (optional). Clean up and modify Console.Au3 content. Add an option to have to type a login password (optional). Make an optional installer that also gives scripts for this tool a custom icon and open with command. ...Call Neo?  
      Thanks to:
      xxaviarxx: debugging, some ideas. jguinch: debugging, adding a bunch of tweaks and ideas. kylomas: debugging, new ideas.  
      Edits and updates:
      Added usage of tab key in edit control Edit has focus now on startup I'm currently rewriting a simple custom programming language to implement this tool.

      Hello all ~
      I am running an autoit script on Windows 10 inside VMware Workstation 12 Pro version 12.5.2.  Technically I am remoting into ESXi which has a Domain Controller (DC), WebServer, FilServer, Windows 10, etc.  Using the GUI (i.e. running explorer.exe) I am able to open several different folders successfully.  The desktop, documents, USB external all open without issue.  The network share opening gives me issues.  Whenever I attempt to open \\filserver\users\user\sharedfolder I get the documents folder instead.  I understand that the documents folder is the default for explorer.  I have also attempted to use the letter drive mapped to the network share (Z:) and receive the same result.  When I run this script on Windows 10 alone without  the VM or the ESXi I am able to open the network share without problems.  I have tried to use the net use command to designate a letter M: to the network share folder prior to running the script.  This did not work for me.  
      One additional avenue I think might work is to use the systreeview321 and _GUICtrlTreeView_FindItem to step through the tree looking for the network share.  Once found,  double click on it and see if that opens the shared network folder.  I can click inside the VM with my mouse on the network share and it opens just fine.  Not sure if running up against GUI issues, or permission issues, or what?
      Thanks in advance,
      Davida Crozier

      This script is a subset of a much larger program, but it illustrates what I am dealing with.

      Hi everyone,
      GUICtrlSetState Function example ,i found $GUI_DROPACCEPTED isn't working in windows10 x64(windows_10_enterprise_2016_ltsb_x64).
      if the example put to windows10 x86 or windows xp, the $GUI_DROPACCEPTED is effective,
      the AutoIt Edition is v3.3.14.2.
      any ideas? thanks you.
