using an array for tray menu items

8 posts in this topic

hi

i wonder if anyone can help me with this little problem.

i have an array of tray menu items. by the time the array is created i will not know how many elements it contains as it can vary depending on system configuration. how can i perform case statements on each element in the array but not go past the max index?


Please note: If you plan on submitting any code snippits to my posts, please refrain from using the code tags as i use a screen reader and can't read the code properly, let alone copy it the way it should be.Thanks for your understanding.Best regardsXY16

Hi,

Look in the help file for UBound().

hi smartee

ubound does in deed give me the max index, kinda like ArrayMaxIndex does, but i don't know where to start when performing case statements. i have tried using loops, an example is below.

$Array[0] = TrayCreateItem("Item1")

$Array[1] = TrayCreateItem("Item2")

$Array[2] = TrayCreateItem("Item3")

;etc

$Items = UBound($Array, "0")

While 1

$msg = TrayGetMsg()

$Count = "0"

While 1

Select

Case $msg = $Array[$Count]

MsgBox(64, "Info", "Item " & $Count & " was selected.")

if $Count > $Items then ExitLoop

EndSelect

WEnd

WEnd

this doesn't work. i would rather not use an array, but can't figure out how to create a variable named based on a counter, for example $MyVar$Counter.

Any ideas?

XY16,

This is one way to do it:

#include <Array.au3>

; So we can finally exit

HotKeySet("{ESC}", "On_Exit")

; Create the array

Global $aArray[3]

$aArray[0] = TrayCreateItem("Item1")

$aArray[1] = TrayCreateItem("Item2")

$aArray[2] = TrayCreateItem("Item3")

;etc

; So you can see the values - I get 7, 8, 9

_ArrayDisplay($aArray)

; Strat a timer to simulate a click on the tray

$iBegin = TimerInit()

; Our idle loop

While 1

; Get the event - although here we will never change as there is no change!

$iMsg = TrayGetMsg()

; Simulate a message after 1 Sec - change the value to change the result

If TimerDiff($iBegin) > 1000 Then $iMsg = 8

; Loop through the array to see if the value is within it

For $iCount = 0 To UBound($aArray) - 1

If $iMsg = $aArray[$iCount] Then

; It is!

MsgBox(64, "Info", "Item " & $iCount & " was selected.")

; And exit the For...Next loop - here you will get a continuous firing of the same value as there is no tray to change the value

ExitLoop

EndIf

Next

WEnd

Func On_Exit()

Exit

EndFunc

Please ask if anything is unclear. :unsure:

hi

you're example was pretty strait forward, but how can the app tell what item someone clicked?

XY16,

"how can the app tell what item someone clicked?" - You just use the $iCount variable. :>

To make life easy, I would add another array (or another dimension in the same array as I have shown below) which tells the app what function to run when that particular item is clicked:

#include <Array.au3>

; So we can finally exit

HotKeySet("{ESC}", "On_Exit")

; Create the array

Global $aArray[3][2] ; [0] is ControlID, [1] is function to run

$aArray[0][0] = TrayCreateItem("Item1")

$aArray[0][1] = "Function_0"

$aArray[1][0] = TrayCreateItem("Item2")

$aArray[1][1] = "Function_1"

$aArray[2][0] = TrayCreateItem("Item3")

$aArray[2][1] = "Function_3"

;etc

; So you can see the values - I get 7, 8, 9

_ArrayDisplay($aArray)

; Strat a timer to simulate a click on the tray

$iBegin = TimerInit()

; Our idle loop

While 1

; Get the event - although here we will never change as there is no change!

$iMsg = TrayGetMsg()

; Simulate a message after 1 Sec - change the value to change the result

If TimerDiff($iBegin) > 1000 Then $iMsg = 8

; Loop through the array to see if the value is within it

For $iCount = 0 To UBound($aArray) - 1

If $iMsg = $aArray[$iCount][0] Then

; It is!

Call($aArray[$iCount][1])

; And exit the For...Next loop - here you will get a continuous firing of the same value as there is no tray to change the value

ExitLoop

EndIf

Next

WEnd

Func Function_0()

MsgBox(0, "Hit!", "The user clicked Item 0")

EndFunc

Func Function_1()

MsgBox(0, "Hit!", "The user clicked Item 1")

EndFunc

Func Function_2()

MsgBox(0, "Hit!", "The user clicked Item 2")

EndFunc

Func On_Exit()

Exit

EndFunc

All clear? :unsure:

to add to my last post, i think it wasn't working properly for me because the TrayAutoPause option is enabled by default, i disabled id it and now everything works fine.

once again thanks for all you're help.
