make a certain window uncloseable ;)

[Kiti]

Update: NO BUGS now, it only blocks the specified window. Completly stealth. Move the mouse to the top LEFT corner of the screen to quit.

Here's my script! It has no tray icon, no taskbar box, there's nothing visible on the screen and it only prevents the specified window from beeing closed. Maybe some of you (who are parents), are afraid to let the computer alone to go to the toilet, because their kids will close their all so important work (at least, that's what I'm doing to my father ) I've done it with the help of ChrisL's transparent control function. I thought it's something useful for some, and that's why I've decided to post it. Of course some programs has the Files->Exit menu, but this is easily made by putting the transparent box on "Files" and, on click, it sets the state of the second gui to show.

Tell me if you like it, and if you find it useful.

What if the window is not on top? What if somebody opens another window infront of the 'protected' window? Would there be controls on the top window that get blocked?

What if the window is not on top? What if somebody opens another window infront of the 'protected' window? Would there be controls on the top window that get blocked?

That's why I've put the If. But now I realized that $a>=32 is not the best condition. I'll have to use BitOr. I'm thinking at what it should be, so only the previously selected window cannot be closed...

While 1
    $a = WinGetState("Title")   ;THE NAME OF THE WINDOW YOU DON'T WANT TO BE CLOSED GOES HERE
    If $a >= 32 Then
        GUISetState(@SW_SHOW)
        $Note_win = WinGetHandle("Form1", "")
WinSetOnTop("Form1", "", 1)
    Else
        GUISetState(@SW_HIDE)
    EndIf
WEnd

I'm having some a little trouble at distiguishing the terms that the window: exists/ is visible/ is enabled/ is active/ is maximized.

When a window is enabled?

Can you explain what your script is meant to do? I know you said it was to stop the window being closed but it doesn't and it's not obvious to me how it was meant to.

[Kiti]

Can you explain what your script is meant to do? I know you said it was to stop the window being closed but it doesn't and it's not obvious to me how it was meant to.

If you replace that "Title" with an actual name of one of your window, it will really block any attempt to close that window by pressing the top right red button.

My script creates an empty, transparent, always on top label, placed like a shield over the "X" button, to catch any clicks.

The point was to make a loop that sounded like this: "If your window is active, set the state of your label to @SW_show.":

While 1
    $a = WinGetState("Title")
       If BitAnd($a, 8) Then                      ;;;;here's all the problem
        GUISetState(@SW_SHOW)
        $Note_win = WinGetHandle("Form1", "")
        WinSetOnTop("Form1", "", 1)
        sleep(10)
    Else
        GUISetState(@SW_HIDE)
    EndIf
WEnd

But here comes the buggy part, if your window is active, it will activate the label, so it won't be active anymore.

In the first post there, instead of If BitAnd($a, 8) Then is If $a >= 32 Then, and this is true when the window is maximized, but anyone can put another window on top, without minimizing the specified window.

I'm trying to find a way to use WinGetState and an "If" loop with that value (and a BitAnd), without involving the value "8" -- Window is active.

I did set the title as you noted in your script. I tried 3 different applications and I could close them all. Is it assumed that the window is maximized and the title bar is at the top of the screen? If so that won't work all the time. You would need to find if the window is active then move the label over the title bar wherever it is. Also, you would need to set the parent for the app to a hidden window to stop it appearing in the task bar where someone could select close.

I think it would be easier to hide the application completely and then show it using some hot keys. And if the "Windows Task Manager" appears then close it.

[Kiti]

I've finally succeded!! Edited post #1, see it there. Now it's working 100%, no bugs, no other windowses blocked. Completely stealth, put mouse button on the top LEFT corner to close.

Is it assumed that the window is maximized and the title bar is at the top of the screen?

Yes, it only works for a 24x24 pixels square, with the it's up and right edges sticked to the right and up edges of the screen.

You would need to find if the window is active then move the label over the title bar wherever it is.

Yep, this is very simple, it's the same thing, but using the client coords.

Also, you would need to set the parent for the app to a hidden window to stop it appearing in the task bar where someone could select close.

The ONLY place where it appears is it in Processes tab in Task Manager, not on the task bar, nor on the tray.

I think it would be easier to hide the application completely and then show it using some hot keys.

It is hidden completly. I've set that if you put your mouse on the top left corner of the screen it shows up.

And if the "Windows Task Manager" appears then close it.

Not really...If so, even a noob will close it 100% sure if it just starts task manager. What if I rename the process, so they won't know which one to close?

I don't think you understood what I was trying to say.

Wow, that's cool. My fault, I understood that when task manager appears close it, the script. But anyway, I don't want to go that far. The reason I made it was that I had another script with a function on exit. And if another window was closed, it couldn't complete it's last function. This way, I've restricted the order in which the programs can be closed: first, my script and second, the window. This was my actual goal. To prevent closing some other window before the script.
