Make a button visible when Notepad is opened

[Alexxander]

Hi all

i want to make a script :

while notepad is running a button is visible and when Notepad is not running the button is not visible

and when i press the button try.exe is opened

#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>

$GUI = GUICreate("MY GUI", -1,-1,-1,-1, $WS_POPUP , $WS_EX_TOPMOST)
$but = GUICtrlCreateButton("", -1, -1, 100, 100)

guisetstate()



While 1
    $nMsg = GUIGetMsg()
        WinSetOnTop($GUI, "", 1)
    $menu = WinExists("[CLASS:Notepad]")
    if $menu = 1 then GUICtrlSetState($but, $GUI_SHOW)
    if $menu = 0 then GUICtrlSetState($but, $GUI_HIDE)
    If $nMsg = $but Then ShellExecute("C:\auto\try.exe")
WEnd

it is working but the button is flashing when start menu is opened and it is not exciting the try.exe when the button is pressed any ideas ?

PS: i'm using win 7

Hi,

The button is flickering because you change its state constantly, I would add a boolean to toggle the state only when needed.

it is not exciting the try.exe when the button is pressed any ideas ?

Where is the exit code?

In other terms:

Local $fMyBool = True
;or
Local $fMyBool = False

sorry i meant executing not exciting

It should work.

Generally you don't want to set a state in a tight loop. That's just asking for flashing and other graphical glitches.

 

WinExists is not quite what you want either. When you close notepad it hides the window, and only deletes it later (there shouldn't be a huge delay, but I'm using a pretty old computer so it's noticeable).

 

Anyway, I changed the code a bit and it works now. No idea what issue it was stopping your code from working, possibly NOTEPAD wasn't matching any windows, and was matching the start menu somehow. Can't reproduce here on xp.

 

#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>

$GUI = GUICreate("MY GUI", 100, 100, 500, 500, $WS_POPUP, $WS_EX_TOPMOST)
$but = GUICtrlCreateButton("", -1, -1, 500, 500)
GUISetState()


Local $fShown = True, $h
While 1
    $nMsg = GUIGetMsg()

    $h = WinGetHandle("[CLASS:Notepad]")
    $menu = Not @error And BitAND(WinGetState($h), @SW_SHOW)

    If $menu <> $fShown Then
        GUICtrlSetState($but, $menu ? $GUI_SHOW : $GUI_HIDE)
        ConsoleWrite($menu & @LF)
        $fShown = $menu
    EndIf

    If $nMsg = $but Then ShellExecute("C:\auto\try.exe")
WEnd

Mat

 

thank you bro but i'm getting error at this line

GUICtrlSetState($but, $menu ? $GUI_SHOW : $GUI_HIDE)

maybe the "?" mark ?

[FireFox]

The ternary operator is implemented in the beta version.

If $menu Then
    GUICtrlSetState($but, $GUI_SHOW)
Else
    GUICtrlSetState($but, $GUI_HIDE)
EndIf

Br, FireFox.

My bad. I'm getting so used to using the new features that I forget they aren't present in the latest stable.

The stable version still has a function called _Iif in Misc.au3 that is nearly an equivalent to the ternary operator (no difference in this case).

Guys may u take a look on my new thread ?

Personally I would use - If ProcessExists("Notepad.exe") Then

But there could be reasons you may not want that method.
