How to hide GUI icon (not tray icon)?

[Mingre]

Hello,

I learned about GuiSetIcon() but how do I use it to hide the icon on the title bar?

Thank you for helping.

Edit:

How do I also hide the GUI's taskbar icon?

You want to completely remove the icon, not just replace with an empty one?

[Mingre]

Oh, yeah.

But if there's no way to completely remove it, making it 'empty' would do.

You can create a custom window class or take a class without an icon, but you will have to use some WinAPI functions. I will be glad to do it for you if it's the last solution.

[Mingre]

Hello FireFox, please do. The helpfie does not provide example for WinAPI functions so I guess I can't make it myself.

Thanks!

[FireFox]

Wait, I still wonder if someone has a better solution to offer

Steam GUI example:

I think all you need is to use style $WS_POPUP in GUICreate.

Another example using WS_POPUP:

Are you asking to have no systemtray (Right bottom) Icon or no Icon on the TaskBar (Left of the Systemtray)?

This here?

Haha! Sure take your time. It's only a favor anyway.

Sorry if I had not made it clear, but I asked this question thinking that hiding the GUI title bar's icon would also hide the taskbar icon. Your examples proved otherwise.

The title bar and taskbar icons please if that's possible.

I tried this but AutoIt does not recognize SetClassLong(). Tried to replace it with _WinAPI_SetWindowLong() (because they look similar, haha!) but still not working.

Edit: grammar

It seems like it's not possible to remove the window taskbar icon.

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

Local Const $GCL_HICONSM = -34, $GCL_HICON = -14

Local $hGUI = 0, $hIcon = 0

#region GUI
$hGUI = GUICreate("MyGUI", Default, Default, -1, -1, -1, $WS_EX_DLGMODALFRAME)

$hIcon = _WinAPI_GetClassLongEx($hGUI, $GCL_HICON)
_WinAPI_DestroyIcon($hIcon)

_WinAPI_SetClassLongEx($hGUI, $GCL_HICON, 0)
_WinAPI_SetClassLongEx($hGUI, $GCL_HICONSM, 0)

GUISetState(@SW_SHOW, $hGUI)
#endregion

While GUIGetMsg() <> $GUI_EVENT_CLOSE
    Sleep(10)
WEnd

GUIDelete($hGUI)

You will need to set a transparent icon.

Br, FireFox.

Hey, thank you!

I tried using GuiSetIcon() with a transparent .ICO but the gap between the edge and the title text looks unpleasant. Haha.
