Substract icon from window

[SaphuA]

Hello,

Is it possible to substract/use the icon that a window uses? I do not need the actual file; I just want to use the icon in my GUI.

Thank you!

I've been looking around a little and I guess I have to use something along the lines of 'SendMessageTimeout' or DLL-calls. The only problem is that I'm not that advanced with AutoIt yet. Anyone got some tips for me?

Do you wish just to have the icon of something els to use in your program, or do you actually want something for autoit to take and use temporarily?

If you just want an icon to compile with, look up the resource hacker thing

If I understand you right then use Scite4AutoIt3 and

#AutoIt3Wrapper_Icon=your_app_icon.ico

#AutoIt3Wrapper_Res_Icon_Add=C:\Program Files\AutoIt3\Icons\au3.ico

#AutoIt3Wrapper_Res_Icon_Add=C:\Program Files\AutoIt3\Icons\filetype1.ico

...

No you're both wrong.

I want to use the icon of any window handle, and use that icon in my gui.

Perhaps it's possible to see what executable file opened the window and use the icon from that executable?

Thank you!

Look at _WinAPI_ExtractIconEx() and search forum for more examples.

You have to use WM_GETICON http://msdn.microsoft.com/en-us/library/ms632625(VS.85).aspx

Then you get a handle, whih represents the Icon and you can use it With WM_SETICON for your gui

This?

#include <WindowsConstants.au3>

Global $GCL_HICONSM = -34
Global $GCL_HICON = -14

$hGUI = GUICreate("Test", 300, 200)

GUISetState()

Run("notepad.exe", "", @SW_MINIMIZE)
WinWait("[Class:Notepad]")
$hNotepad = WinGetHandle("[Class:Notepad]")

MsgBox(0, "", "Change GUI icon")

$hIcon = DllCall("user32.dll", "int", "GetClassLong", "hwnd", $hNotepad, "int", $GCL_HICON)
$hIcon = $hIcon[0]

If $hIcon = 0 Then
    $hIcon = DllCall("user32.dll", "int", "GetClassLong", "hwnd", $hNotepad, "int", $GCL_HICONSM)
    $hIcon = $hIcon[0]
EndIf

DllCall("user32.dll", "int", "SendMessage", "hwnd", $hGUI, "int", $WM_SETICON, "int", 1, "int", $hIcon)

DllCall("User32.dll", "int", "DestroyIcon", "hwnd", $hIcon)

WinClose($hNotepad)

Do
Until GUIGetMsg() = -3

Seems like it! Awesome! Thanks

Btw, I was just wondering, how do you guys know what functions these DLL's contain and how to use them?

[ProgAndy]

E.g. from Microsoft

MSDn -> WinAPI : http://msdn.microsoft.com/en-us/library/aa383749(VS.85).aspx

or from examples in other languages like VB, delphi, ...

Phew, I'm trying to get this to work with:

http://www.autoitscript.com/forum/index.ph...l=ModernMenuRaw

But I want to change the icons of the context menu items, but they don't accept a pointer, only a file.

Is there a way I can either temporarily save the icon, make it accept pointers or are their alternate sources available like that one?
