Hide/disable closing x-button

Recommended Posts

Is it possible to hide or disable the upper-right-corner close-window button? I want to run a command prompt doing something, and want the user to see whats going on, but not be able to close that dos window...

as far as I know you cannot remove the header/Window bar on a windows generated window (hope that makes sense)

However, as an idea only, you could run your dos window application in a full screen or maximized window and create a long narrow gui with the top-most attribute that would cover the minimize/maximize buttons and maybe place a label like " DOS WINDOW OPERATION, PLEASE WAIT.

as long as the text is more to the middle/left it wont matter if your narrow GUI is longer than the screen ( if a user has 640 x 480 display) it would still work

they could still close/minimize on the very bottom bar, however, the message would raise the chance of the end user just watching and not clicking on anything

hope it helps

Did use a variant of the window over dos-promt temporarily. Used a splash-screen with transparency, and made a second script that sets focus to the splashscreen if the user tries to set focus to the promt by clicking it on the taskbar.

But hiding the buttons is nicer, and gafrosts link looks really interesting. I'll give it a go tomorrow.

Had a go using gafrosts example code, but found I lack one of the include-scripts used; ANYGUI.au3. It seems that this include-script contains the function _GuiTarget, witch is used to get the windows handle. How do I find this include-script? Or is there any other way to get the handle of the currently active window?

(Tried to use @GUI_WINHANDLE but it seems to work only for autoit-created gui-windows....)

From the help file:

Retrieves the internal handle of a window.

WinGetHandle ( "title" [, "text"])


title The title of the window to read.

text [optional] The text of the window to read.

Return Value

Success: Returns a string containing the window handle value.

Failure: Returns "" (blank string) and sets @error to 1 if no window matches the criteria.

It works :) Thank you!

One more thing, I only want to disable the close button. To be sure to delete the correct menuitem, I tried to get the menustring by using:

$ret2 = DllCall("user32.dll", "str", "GetMenuStringA","hwnd",$hWnd,"int",$menuitemnumber,"ptr",$tmp,"int",$menustringlengthplusone,"str","MF_BYPOSITION")

This syntax does not work, I can't figure out how to do the pointer-parter from autoit. Any ideas?

That would require the beta version of AutoIt and using the DllStruct* functions

if you wan't to remove the close button only "X" then here's a modified example of what i did for someone else, the "X" should be System menu item 6

#include <Array.au3>
#include <ANYGUI.au3>
#include <guiconstants.au3>
#Include <GuiTab.au3>

Opt ("WinTitleMatchMode", 3)
Opt ("WinWaitDelay", 0)
Opt ("GUIOnEventMode", 1)

Const $MF_BYCOMMAND = 0x0
Const $MF_BYPOSITION = 0x400
Const $MF_REMOVE = 0x1000

$pid = Run("notepad.exe")
WinWait("Untitled - Notepad")
WinWaitActive("Untitled - Notepad")
$hWnd = _GuiTarget ("Untitled - Notepad", 1)

Ok, I also figured out that "close" is menu item 6. I think I will use this for now and have a look again when the next version of autoit is released. "Menu item 6" should probably work on w2k and wxp at least.

Thank you again!
