Error: Subscript used with non-Array variable

[Noob]

While 1

$size = WinGetClientSize("Untitled - Notepad")
if $size[0] = 1024 Then MsgBox(0, "", "Hello")

Sleep(100)

WEnd

When I run the above code I get: Error: Subscript used with non-Array variable

My intention is to know when a window is of a certain size (full-size mode, to be exact). But I simplified my code to illustrate how I'm attempting to do it.

Any help would be extremely appreciated, as I've been playing with this for ever a week.

How about using WinGetState instead? Look at the help example.

If WinGetClientSize() does not find the window, it will NOT return an array. See help file. Check @error to figure out if there was an error!

Joon, my intention is to compare WinGetClientSize("Program Manager") to WinGetClientSize("MyWindow") in order to determine if my window is in full-screen mode. Unfortunatelly the WinGetState function I don't think can tell me if an an application is running in full-screen mode. The Help file says the WinGetState function can tell if a window is maximized, minimized, etc, (but not full-screen mode).

First of all why limit yourself to 1 desktop size?

Try

$Ttl = "My Window"
WinWaitActive($Ttl)
$Sz = WinGetPos($Ttl)
If $Sz[2] = @DesktopWidth Then MsgBox(4096,'Winner', "Bet your sweet butt that it's full width")
MsgBox(4096,' Try Again', 'Use @DesktopWidth and $Sz[3]')
If $Sz[2] = @DesktopWidth AND $Sz[3] = @DesktopHeight Then MsgBox(4096,'Wow!!',"It's full screen too')
Have_aDrink()
Exit

Kurt, thanks for reply. I tried the script again, and yes, you are right. If WinGetClientSize() does not find the window, then it gives me the error. If the window is active I don't get the error.

So basically I think it is working fine, but I just need to prevent the ERROR from appearing. I'm new to this (and I will most likely stay a noob at this forever), but if someone would be patient enough with me to show me how to turn off the error message (or all error messages) I'd be very grateful. I looked at the @error function in the help file, but it's a bit complicated for me :-(

Like Kurt said, maybe windows does not exist. try with WinExist condition.

If WinExists("Untitled - Notepad") Then
    $size = WinGetClientSize("Untitled - Notepad")
    If $size[0] = 1024 Then MsgBox(0, "", "Hello")
EndIf

While 1
    $size = WinGetClientSize("Untitled - Notepad")
    If IsArray($size) Then
        If $size[0] = 1024 Then
            MsgBox(0, "", "Hello")
        EndIf
    EndIf
    Sleep(100)
WEnd

You could also check @error after $size = WinGetClientSize("Untitled - Notepad") and use an if statement to proceed if it is an array, or do something else if it isn't

[Valuater]

same concept as above, however i would have just added IsArray() to the original posters code

While 1

    $size = WinGetClientSize("Untitled - Notepad")
    If IsArray($size) And $size[0] = 1024 Then MsgBox(0, "", "Hello")

    Sleep(100)

WEnd

That was his original code

[Joon]

That was his original code

Valuater added IsArray

If IsArray($size) And $size[0] = 1024 Then MsgBox(0, "", "Hello")

Yes, which is all I did. Hence I used the original code?

[Valuater]

"Hello"

lol

It works, it works, it works!!!

You guys are the best!!!

Thanks much for all who took the time to reply! I'm looking one-by-one at the code suggestions (and I'm learning new stuff!).

The one that was the easiest for me to implement in my situation was the code suggested by Valuater. It's been added to my little app already, and this was it seems the last piece I needed :-)
