Reference an array with a string?

Recommended Posts

Sarg

After much experimentation, I discovered that I could read from an array with a string reference like so:

CODE

Const $num_PCs = 13

Const $num_attrs = 12

Const $IPAddr = 3

Const $SubMask = 4

Const $DefGate = 5

...

...

...

Func qr ( $sArrayName, Const $iElement ) ; this is the function in question, qr for Quick Read, takes a string and an index

Local $iTrueElement

If IsNumber($iElement) Then ; if iElement is really an index ...

Return Execute("$avPC_" & $sArrayName & "[" & $iElement &"]") ; ... then read the value and return it

Else

$iTrueElement = Execute("$" & $iElement) ; otherwise convert it to an index by using the constants

Return Execute("$avPC_" & $sArrayName & "[" & $iTrueElement &"]") ; ... and read/return that

EndIf

EndFunc

...

...

...

Dim $avPC_List [$num_PCs] = ["ttinsley","knguyen","jsmith","bwendall","tamhearst","wfarmer","sbrindal","jwerner","hfelton","vtucker","melder","aricker","dashmore"]

Dim $avPC_ttinsley [$num_attrs] = ["ttinsley","MG97F3","Indianapolis","10.125.24.51","255.255.254.0","10.125.24.1","Win2k3",1494,"c:\vpnclient\corp_primary.pcf",1,0,0]

...

...

...

Local $sActive_PC = ""

...

For $sPCCounter in $avPC_List ; Loop through the list of PC, by username

$sActive_PC = qr($sPCCounter,"IPAddr") ; set sActive_PC to the IP Address located in the PC's array

...

...

...

This works well. However, the same can not be said for the function to alter the information in the array! No matter what I try, it just refuses to set. I managed to get it to store "$avPC_bwendall[11] = 2" in a variable named $setthis (my frustration is showing!) but even Execute($setthis) isn't doing anything.

Anyone able to lend a hand?

Do you have any code where u attempt to do this?

Posting your code really helps - also don't forget to add indents for readability.

Lastly welcome to the forum.


Post your code because code says more then your words can. SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y.

To set a variable using a string you need Assign BUT it can't be used with arrays. You would have to have an array of arrays and pass elements only to do what you want.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
