I am currently using Autoit's "WinList" function in an Autoit script, I fully understand it.
Autoit provides a nice Library for Word VBA so that Some of Autoit's functions can be used within a MSWord VBA script, some of which I am using.
I have a use for Autoit's "WinList" function which has been provided by AutoIt in their Library for MSWord VBA scripting. The WinList function Creates an array when run. MSWord VBA does not seem to allow this. To create an array in VBA you have to first DIM it, and this does not seem to work for the WinList function.
Dim AutoIt As New AutoItX3Lib.AutoItX3
MyArray= Autoit(WinList) produces an error, whether I dim the array or not.
It seems that AutoIt has provided a function for VBA that cant be used ??
Can someone figure out a way to use WinList within Word VBA?
It's been a while since I've used AutoIt, but I'm having fun with it again.
I'm running on Windows 7 Pro, 64_bit. with AutoIt 22.214.171.124+
In my program, I've called Winlist(), so that I can get a list of all windows on the system.
I then iterate through the titles, and attempt to copy the title & handle of Windows I'm specifically interested in.
While this seems to be a very easy task, I'm having a strange problem copying the title & handle of the two windows that I'm interested in.
In the For loop:
For $i = 1 To $AllWindowsCount ConsoleWrite() displays the expected Title & handle, from the WindowsDupe array, so it appears that the copy from the $AllWindows array
works as expected.
_ArrayDisplay($WindowsDupe) is called after the for loop, $WindowsDupe is empty.
I wasn't able to find any functions in the help file, for copying entire arrays or certain elements, so I thought I would just copy them manually, as seen in the for loop.
What am I doing wrong with the WindowsDupe array?
My code is attached.
So the code I use is as follows:
Local $InstancesList = WinList("[REGEXPTITLE:(?i)(.*Paint.*|.*WinAmp.*)]")
And then if this number changes, I do something. But once in a while I SEE a new window paint being opened but nothing happens.
So I added logs and printed the InstancesList and saw it did not pick up the new paint.
Now I also added a WinList with Class to doublecheck, but still now and then it fails. So I was wondering if this is a known problem, and whether there are alternatives of workarounds.
Hi, I use winlist to count the amount of instances of a specific window (in combination with a reg expression). Over multiple runs, it seems that it fails 1 in a hundred times more or less. Any idea how/why? And are there alternatives to use as a backup/check?
All my tests done on WinXP SP3, AutoItX v126.96.36.199
My AutoItX is not up-to-date, however the changelog does not record any change regarding this problem.
The issue is known :
* each call to o_AutoItX3Obj.WinList can consumme up to 4ko (in my tests),
which are not released even when exiting a sub or setting the o_AutoItX3Obj object to Nothing
-> this is a problem, for example, for ever-runnning scripts that do repetitive call to WinList
* a work-around : enumerate windows instead of using WinList

* note 1 :
enumerating windows could have timing issues if some windows matching the criteria
are appearing/disappearing while doing the enumeration... (I didn't test that)
* note 2 :
if it impossible to avoid memory leak in COM components returning arrays,
then WinList could return a simple string with titles/handles separated by Chr(0),
(assuming there are no Chr(0) inside window titles ?)
then the user would use the Split function to get an 1-Dim array : [title1, handle1, title2, handle2, title3, handle3] etc...
This string-type return could be an optional parameter given to the WinList function :
arr = o_AutoItX3Obj.Winlist("title" [, "text" [, return type]])
