TrayItemCreate() Limit?

[MrCreatoR]

Hi all,

I have notice that when you create more then 510 tray items dinamicly, the event of the last item (wich is Exit in my case) is called...

Check this example...

expandcollapse popup

HotKeySet("^i", "Input")
Opt("TrayMenuMode", 1)

Global $OptionsArray[4]
Global $DefaultNumber = 1

$ChooseOption = TrayCreateItem("Set Number of Tray items..")

For $i = 1 To UBound($OptionsArray)-1
    $OptionsArray[$i] = TrayCreateItem("Item " & $i)
Next

$Seperator = TrayCreateItem("")
$ExitItem = TrayCreateItem("Exit")

While 1
    $TrayMsg = TrayGetMsg()
    Select
        Case $TrayMsg = $ChooseOption
            Input()
        Case $TrayMsg = $ExitItem 
            Exit 1
    EndSelect 
WEnd

Func Input()
    $Ubound = UBound($OptionsArray)
    
    While 1
        $Var = InputBox("", "Type number of Tray Items:", $DefaultNumber)
        If @error Then Return
        
        If StringRegExpReplace($Var, '[^0-9]', '') = '' Then
            MsgBox(48, "Attention!", "Typed an incorrect number" & @LF & "Please type again..", 5)
            ContinueLoop
        EndIf
        ExitLoop
    WEnd
    
    If $Var = $Ubound-1 Then Return
    
    TrayItemDelete($Seperator)
    TrayItemDelete($ExitItem)
    
    If $Var > $Ubound-1 Then
        ReDim $OptionsArray[$Var+1]
        For $i = $Ubound To $Var
            $OptionsArray[$i] = TrayCreateItem("Item " & $i)
        Next
    Else
        For $i = $Var+1 To $Ubound-1
            TrayItemDelete($OptionsArray[$i])
        Next
        ReDim $OptionsArray[$Var+1]
    EndIf
    
    $DefaultNumber = $Var
    
    $Seperator = TrayCreateItem("")
    $ExitItem = TrayCreateItem("Exit")
EndFunc

Press Ctrl I (or select item "Set Number of Tray items.." from the tray menu), type there number 510, then script is exiting (i mean exiting by event, check it using 1 after Exit command).

If you type a lower number then 510, then everything is ok, the script is not exit...

When i change it to events mode (Opt("TrayOnEventMode", 1)), this problem not exists (after few tunings), but i can not understand what the problem here with standard mode?

I guesing that this is because the TrayGetMsg() return always zero if there is no messages, but when i delete the Tray Item and recreate it again, variavble of this item become to be zero as well (the Exit Item) - Maybe this is a bug of TrayCreateItem()?

According to the help file the limit is 505 items although it runs in my mind (easily wrong) that it didn't crash for me until I was close to 700

Do 510 tray items even fit on the screen?

[Siao]

Fact is you don't need to delete that separator and Exit control to insert items.

And it works fine with more than 65535+ controls on my WinXP.

The limit documentation is probably for Win95 support, as usual.

Thanks Siao, i forgout about the aditional paramters...

But why it's happend with my example? i mean, why when i create 510 items the $ExitItem is = 0?

Oh i see now, because the limit, last item is not created, this why it returns 0... it seems that you beat the limit Siao - Maybe we should report about it (for doc clarification).

Yea, it would seem that specifying menuentry parameter makes AutoIt skip that silly max items check...

otherwise the last possible controlID is 518 and then it resets to 0

Probably right. When I last wrote a major tray app (about 2 years ago) we didn't have the parameter.

No. They scroll just like a long menu.

Are you sure? i mean, there is really that much item created? you can check it if you move the mouse over the toppest item (when you click on the tray icon), and press Up key on the keyboard.

Because i can't get it work, it create only 513 items (if i use no second parameter, then only 511).

Perhaps there is a difference in what's beng created here? Try using TrayCreateMenu() for the first 510 and then see if you can create 510 MenuItems for each of those.

Yes, but i thought that Siao has created that mutch items in one menu
