Modify Window Style of Foreign Window - add minimize button

[Knight 2]

I have a third party application that launches a window with a title bar but no exit or minimize buttons on it. Is it possible to add these buttons, specifically minimize, to that window with an AutoIt script?

You can't add buttons to an external program GUI, however you could possibly make a separate tool window with buttons to minimize and maximize the GUI. It may even be possible to somehow float an image over the top right hand corner of the original window and click on that. That's a bit too complicated for me though.

This.

#include <WindowsConstants.au3>
#include <WinAPI.au3>
#include <Constants.au3>

Global $Check = False

$hGui = GuiCreate("Change/UnChange WS_MAXIMIZEBOX",250,30)
$iAction = GuiCtrlCreateButton("Remove WS_MAXIMIZEBOX to Calc",0,0,250,30)
GuiSetState()

Run("Calc.exe")
WinWait("[CLASS:CalcFrame]")
$hWinHandle = WingetHandle("[CLASS:CalcFrame]")
$dwStyle = _WinApi_getwindowlong($hWinHandle, $GWL_STYLE)

While True
    $iMsg = GuiGetMsg()
    Switch $iMsg
        case - 3
            WinClose($hWinHandle)
            Exit
        case $iAction
            If $check = false Then
            _WinAPI_SetWindowLong($hWinHandle, $GWL_STYLE, BitAND($dwStyle, $WS_MAXIMIZEBOX))
            $check = Not $check
        Else
            _WinAPI_SetWindowLong($hWinHandle, $GWL_STYLE, $dwStyle)
            $check = Not $check
        EndIf
    EndSwitch
WEnd

The Bug is because the style changing is a little more complicated, but not too much.

It just locks up the window.

Try using the window information tool to get window info, and check out WinSetState in the help file.

Edit

Some custom GUIs are not so easy to automate, and there is no guarantee that it will work.

I found a solution that works using ANYGUI.au3. It is available on this forum.

#include <AnyGUI.au3>
#include <WindowsConstants.au3>

$win = "Calculator"
$hwnd = _GuiTarget($win)
_TargetStyle("set", 1, $GUI_SS_DEFAULT_GUI, -1, $hwnd)
_EndTarget()
