Error handling

[boogieoompa]

Normally this has never been an issue before but I am having some segments of code check for window properties such as state and whether or not it exsists. However with my current code snipit the $size=wingetpos is notactually triping the error if statement. It is instead triggered witht he MsgBox. Basically I need to know what segements of my code errored otu by setting properies so if someone could be so kind as to explain what function willl check for errors without doing anything else other than perhaps set a variable

Thank you

$size = 0
Opt("WinTitleMatchMode", 2)
$size = WinGetPos(".P343")
if @error Then
    MsgBox(0,"","Please remove the appbar from docking mode" & @error);
    $position = 0
Else
    $position = 1
endif
MsgBox(0, "Active window stats (x,y,width,height):", $size[0] & " " & $size[1] & " " & $size[2] & " " & $size[3] & " " & $position)

If the window is minimized then that could explain your problem. Then you would need this perhaps (not tested)

$size = 0
Opt("WinTitleMatchMode", 2)
$size = WinGetPos(".P343")
if @error Or $size < 0 Then; might be better to have Or not IsArray($size) Then
    MsgBox(0,"","Please remove the appbar from docking mode" & @error);
    $position = 0
Else
    $position = 1
        MsgBox(0, "Active window stats (x,y,width,height):", $size[0] & " " & $size[1] & " " & $size[2] & " " & $size[3] & " " & $position)

endif

EDIT:added option for If.

Thank you very much for your reply. That seemed to be it except i changed it from if @error Or $size < 0 to if @error Or $size = 0 since i set it to 0 just before and the wingetpos was not returning anything (which is what it is supposed to catch in this segment of code).

Thank you
