I seem to get this a lot in mIRC, and I know that mIRC is a large cause of this error coming up in Windows, something about hogging heap resources.

Is what I found... and yeh, "ill-behaved applications" makes me lol a bit, but it's still an annoying issue.

I'm regularly in around 75 channels across 6 networks with 10 @windows and various amounts of PM windows, usually around 3. Then there's the close to 25 other open windows I have besides mIRC (browsers, cmd windows, folders, notepad's, other instances of mIRC, trillian, etc) ... In any case, this adds up too fast and mIRC just causes a lot of issues, most likely due to handling how windows are created poorly smirk

I wouldn't begin to know how to fix such a thing, but it would be great if it was fixable because I'd rather not have to go registry hacking to fix something mIRC is breaking on a continual basis. This also means that other Windows windows can't be created or opened when this starts happening in mIRC, also prevents the right click menu from working. Really... there has to be a better solution to how mIRC handles the heap so that it doesn't make everything shit bricks.

You never mentioned what version of Windows you're running. What information do you have that points to mIRC as the problem and not any of the other applications you're running?

This statement would make me wonder how you are determining that it's mIRC that has the bug/causing the problem.

Hmm.. let's do some math.. 75 channels + 6 status windows (1 per network) + 10 custom windows + 3 pm/queries = 94 windows in mIRC.
As you state that you have multiple instances of mIRC running, and if you have the same number of window per instance, and even if you have just one other instance of mIRC running, you're now up to 188 windows + the taskbar windows for all of those other applications, can quite quickly and easily hit the 200+ window mark.

You seem to be blaming mIRC for a limitation in windows. It's windows running out of heap space, not mIRC.

What happens when you increase the desktop heap as described in the article you posted? You tried that, didn't you?

I suffer this problem since long (windows 98 oem), also * Error creating dialog, I wrote a script with a quite large dialog and just opening two mirc instances, no IRC connections, is already enough to not be able to open the dialog of the last started.

It's fixable, in a certain degree, by increasing that value, but the fact is that the original cause is the chosen width of a register, aging back to 1995 and never increased, also not in Vista - a rather serious middlefingerup if you take into account the immense increase of RAM memory since those days, the bigger screen resolutions and faster CPU's and thus the tendency to run more and more applications simultaneous.

In my windows 98, it's even hardcoded (not a registry setting), so I can't do a thing about it.
Drawback is that I'm unable to test with two mirc instances anymore.

So yes, blame Microsoft, not mIRC, it's just mIRC's application nature that makes it more likely to bring up the problem first.

Yep, and windows can only open around 189 windows or thereabouts, and for some reason mIRC is calling each channel a window and abusing the heap as such making it impossible for many other programs to be run when mIRC is hogging the heap in such a fassion.

(The other mIRC instance only has 13 windows)

So yeh, it rapidly hits that mark, and if it wasn't for mIRC calling everything (chans, status windows, pm's, etc) as window events/heap users such as it is, this wouldn't be that big a problem. For example, I have 100 tabs open in Opera at any given time, and it doesn't cause any other issues with the window-opening limit that Windows seems to have. I can close Opera and I get to open one more chan in mIRC, meaning that Opera only takes up one such element on the heap while mIRC is taking up at least 100 by itself. This makes me think there is a much better way to do it if all the tabs in any other application (browsers, pdf, text editors) still only count as one app on the heap.

an opera tab isn't an MDI child window so your comparison is completely moot. You need to compare windows to windows... IE hits the desktop limit at roughly 30 windows (NOT tabs).

Using MDI windows is not "abusing the heap", it's merely using MDI windows. mIRC is not going to change from using MDI child windows in your lifetime, it's one of the features that practically defines the UI, so there's little you can do but increase your heap.

I don't know if it's practical to compare mIRC with applications such as Opera, Firefox or Explorer, which are used for a different purpose, present information in a different way, and have a different level of interactivity.

mIRC is designed to be frugal with resources - however there's only so much it can do when it comes to windows resources where it has to open a new MDI window for every window type that you need, along with any other required resources such as edit box, list box, and scroll bar windows, as well as the supporting infrastructure for that window type. Most other applications, such as browers, do not use MDI windows and do not display more than a single window of information at a time. There are of course no plans to remove MDI support from mIRC. Other applications may also avoid use of resources by using their own custom-drawn resources used instead of standard windows resources. There are no plans to do this in mIRC either. In fact I plan to move away from the current custom-drawn resources in mIRC to standard windows resources in future versions, which may require more windows resources.

Overall, I think it's impressive that mIRC can open that many server, channel, query and custom windows at the same time - the amount of information that's being stored and processed on a per connection/window/event/user/script basis is significant - it's an extreme situation and is probably an indication of how stable mIRC is.

So this problem is gonna become even more worse.

The alternative for a script that intends to initiate alot server connections / join alot channels is using socket connections and do it all yourself (parsing irc protocol etc) from within script code, which I assume gonna be a big performance drag.

So it's a rather very black/white choice.

Maybe there are some options to avoid it?

I tend to use alot hidden custom windows in my scripts, as data structures, /filter'd or /loadbuf'd from txt file upon script's start.

Because a custom window is memory(fast), keeps its order, and has a very powerful command (/filter) available for it.

In this usage, the fact that it is actually a window is unwanted (except for easy direct debugging purposes).
I think mIRC lacks a 'real' data structure with this characteristics.

So I wonder how realistic/do-able it is to provide a choice to have the data structure but not the window, for custom windows, maybe also for other window types (status/channel/?)

Basically like a switch for certain commands that makes them - alike join -n opens a channel window minimized - not create the window as such.
I guess it's gonna depend on how dependent mirc's functions are of actual window-stored data.
Or said in another way: if the window does not exist (like is the case with that * Error creating window), do some mirc functions fail? Or are these windows really just output alone?

If mIRC's functions can do it without actual window presence, then it might be a realistic option.

Forgive me, this is really neither here nor there...

RRX: Can't you do most of that using hash tables? They'd be very quick (they're all stored in memory) and it already doesn't require opening a window.

You wouldn't be able to use /filter but there are many options that become available when using hash tables. I'd also bet that it would be as fast, if not faster, than using /filter. I have no proof backing that up, but it'd be easy enough to test.

Of course there may be scripts using /filter that could use hash tables instead.
But - for example - as items of a hash table are inherently unsorted, everything related to "keep things in order" is a pain (especially regarding performance) or imposible to obtain via hash tables, besides other filter features or related actions like strip, ranges, fast "duplication" of a [part of a] dataset (window content), loadbuf/-save etc pp. smile

Yes, that's the problem with hashes, order and mass operations. I use /filter for about anything, to number, to sort, to extract all entries with certain value(s) on certain token position(s).

mIRC lacks a memorybased data structure that keeps order and /filter-alike commands for it. A hidden custom window is perfect for this, only that the window as-such can be seen as a rather unwanted side-effect, but acceptable.

But this OS heap register size problem is an unforeseen and rather big obstacle in the whole idea, especially for a big script with alot functions where they are used all over the place, as data buffers and holders, queues, joblists, etc.

I only uses hashes for item+value paired configuration data and where order isn't needed and where hdel -w can cleanup for ex all entries for a given network.

However, I did not chose permanent @windows on a per network base, my queues for example use one window for all networks, the network name is just a token-element of a line. It causes abit extra overhead but that's all.

So the main effect of this heap limit is that it defeats the whole purpose of my script: being on alot networks and channels.
There was a day I believed that I could select 20 networks in my dialog, press a 'Connect' button and expecting to find myself, authed or identified on every network and on 100 channels, to act as bot and chat. I wrote a complex queue system to avoid flooding and keep mIRC responsive.

Until I ran into this * Error creating window, at a mere 50 channels or so, and * Error creating dialog when trying to open its interface. It's not fun.

So you're using mIRC incorrectly. windows are not meant to be your data buffers.. they come with the obvious inherent drawback discussed in this topic. You either acknowledge it and change your methods to the proper ones, or you stay stubborn and deal with the limitation. This isn't just a problem with mIRC, it's a problem anytime you abuse the creation of HWNDs to store data, so there's little mIRC can actually do any different than..like, any windows application. Start using hash tables or start using dlls if you need the speed... OR use /filter on files, since theyre a) cached anyway and b) not all that much slower than windows.

Incorrectly.
Improper methods.

Stubborn.
I abuse.

Right!
It's a post of arguev0.
Answer in Funny Style:

I said it - you should know - the post above yours:
I chosed @windows because mIRC has nothing native that keeps its order, is memory-based, and has powerful commands available for it.
So!
Surely it's a poor-mans solution!
But!
You know!
You advised a dll!

Okay, convince me. Show me benchmark results on your most common commands using @windows versus files... I mean, surely you seem to know beyond the shadow of a doubt how much slower it is so you must have done benchmarks, right?

You know what, don't convince me, I'll just do it myself. I'll test mIRC's sorting algorithm, which is probably the slowest part of /filter:

Code:
alias bench {
  var %x = 1, %ticks = $ticks
  while (%x <= 5) { $1- | inc %x }
  echo -a Command completed in (avg over 5 runs) $calc(($ticks - %ticks) / 5) ticks: $1-
}

alias lensort { return $iif($len($1) > $len($2), 1, $iif($len($1) < $len($2), -1, 0)) }


Results:

Note: @tmp1 was loaded with the same logfile before running the test, @tmp2 was empty. #somechannel was changed to protect the innocent, but the file is 247.58KB.. a pretty large sample size for a sorting operation even given only 5 trial runs.

Code:
Command completed in (avg over 5 runs) 3110.6 ticks: filter -ffa logs\#somechannel.log logs\#somechannel.log2 lensort
Command completed in (avg over 5 runs) 3085.6 ticks: filter -wwa @tmp1 @tmp2 lensort


So you're right. Window operations are faster!!!!!!

edit: The excitement was sarcasm, by the way.

edit2: Other uses of filter give similar results. I get 14.19 ticks using window-to-window filtering for a simple wildcard match of *mirc* versus 17.16 ticks using files (avg over 100 runs). As you can see, smaller operations take the biggest hit because the slowdown is due to the overhead in opening the files, not accessing them. At the same time, however, the cost from a smaller operation is equally negligible because the operation is negligible in itself. A difference of 3 ticks is not differentiable, even though it's technically 20% slower.

Glad you turned down your Rumble in the Jumble talk!

Next is some benchmark code that mimics what my script does when a change has to occur.
It is not a setup to win an arguement.
It is really a mimication of the method I use.
I had a /filter problem in the past that proves I store my data this way: http://forums.mirc.com/ubbthreads.php?ub...true#Post177646
A line holds for ex. Network Channel OFF ON OFF and the most common access method is to change a token (here for ex. ON to OFF)
I use /filter (with some exceptions because it still lacks certain things) for mass operations, i.e. affecting more lines, like sorting or, in case a queue, to filter out all entries for a given network.
Code:
alias yay { echo -ag File: $yayF @window: $yay@ }
alias yayF {
  var %i = 1 | while (%i < 1001) { write yay.txt a r g %i v 0 | inc %i }
  var %t = $ticks, %i = 1
  while (%i < 1001) {
    var %rec = $read(yay.txt,nw,& & & 500 & &)
    write -l 500 yay.txt $puttok(%rec,500,4,32)
    inc %i
  }
  .remove yay.txt
  return $calc($ticks - %t)
}
alias yay@ {
  var %i = 1 | window -h @yay | while (%i < 1001) { aline @yay a r g %i v 0 | inc %i }
  var %t = $ticks, %i = 1
  while (%i < 1001) {
    var %rec = $fline(@yay,& & & 500 & &,1).text
    rline @yay 500 $puttok(%rec,500,4,32)
    inc %i
  }
  window -c @yay
  return $calc($ticks - %t)
}

If I type /yay then I see:
File: 3370 @window: 877
As you can see, the @window is almost 4 times faster.

Another example for my usage, I use it in case /filter can't be used due to wildcard symbol problems, if you want to search for a line that contains *!bla@yay.yo in a certain token position, false positives are possible due to /filter's seeing it as a wildcard symbol, same for cases of channel/user modes where the case of the character(s) matter.
Code:
; +++ MAIN FUNCTION BASE / ADVANCED FILTER @WINDOW OR FILE (IDENTIFIER CALL ONLY)
; Input: $1 = name of input window or filename $2 = ascii token separator used in input window
; $3 = <LlWw><position1>,<LlWw><position2>,etc $4 = token matchstring
; L (literal case sensitive) l (literal case insensitive) W (wildcard case sensitive) w (wildcard case insensitive)
; Output: $result = $null or name of results temp window with line format <original line position> <record>
alias SC_filter {
  var %a = $2, %list = $3, %wm = $4
  if (!$window($1)) { var %w = $SC_rw, %src = file | filter -fwc $+(",$1,") %w * } | else { var %w = $1, %src = win }
  var %total1 = $line(%w,0), %total2 = $numtok(%list,44), %i1 = 1, %wr = $SC_rw
  while (%i1 <= %total1) {
    var %rec = $line(%w,%i1), %i2 = 1
    while (%i2 <= %total2) {
      var %tok = $gettok(%list,%i2,44), %pos = $mid(%tok,2), %s1 = $gettok(%wm,%pos,%a), %s2 = $gettok(%rec,%pos,%a)
      goto $+(M,$asc($left(%tok,1)))
      :M76 | if (%s1 !== %s2) { goto nexti1 } | inc %i2 | continue
      :M108 | if (%s1 != %s2) { goto nexti1 } | inc %i2 | continue
      :M87 | if (%s1 !iswmcs %s2) { goto nexti1 } | inc %i2 | continue
      :M119 | if (%s1 !iswm %s2) { goto nexti1 } | inc %i2 | continue
    }
    aline -p %wr %i1 %rec
    :nexti1 | inc %i1
  }
  if ($line(%wr,0)) { return %wr }
  window -c %wr | return $null
}

Notice how I also use temp hidden custom windows with random generated names, as buffer.

mIRC lacks a storage method that is similar to custom windows, and that is in fact all I had and have to say in this thread.
I use custom windows because they suit the most.
The actual 'being a window' is an unwanted side-effect but it's exactly that makes it run into trouble.

Of course your first example is completely invalid because it has nothing to do with /filter. My claim was /filter -ww was as fast as (or only slightly faster than) /filter -ff/-wf/-fw, not that many $read's would be as fast as many memory accesses. That is a completely different function with completely different behaviour. The good thing about your example is that I can still do it with /filter using the -k switch to /write in a callback to some aux file and then merge it back after. I'll leave it as an excercise to you, but I guarantee it's not substantially slower than an $fline loop.

The other good thing about your example though, is that even without /filter, there is still a faster way to do it.. it's called hash tables, which is mIRC's "storage method similar to custom windows" that you so incorrectly claim it lacks. Quickly converting the script to a hash table script,

Code:
alias yay { echo -ag Hash: $yayF @window: $yay@ }
alias yayF {
  var %i = 1 | while (%i < 1001) { hadd -m yay %i a r g %i v 0 | inc %i }
  var %t = $ticks, %i = 1
  while (%i < 1001) {
    var %rec = $hget(yay, $hfind(yay,& & & 500 & &,1,w).data)
    hadd yay 500 $puttok(%rec,500,4,32)
    inc %i
  }
  hfree yay
  return $calc($ticks - %t)
}
alias yay@ {
  var %i = 1 | window -h @yay | while (%i < 1001) { aline @yay a r g %i v 0 | inc %i }
  var %t = $ticks, %i = 1
  while (%i < 1001) {
    var %rec = $fline(@yay,& & & 500 & &,1).text
    rline @yay 500 $puttok(%rec,500,4,32)
    inc %i
  }
  window -c @yay
  return $calc($ticks - %t)
}


you find that:
Hash: 94 @window: 328

So much for faster, again.

Conclusion? Use the right tool for the right job. It really is that simple.

edit: PS. I won't even bother deciphering your second example, but your initial statement is also wrong there. /filter can deal with strings like "*!*@*blah".. use the -g switch to make the matchtext a regular expression and then write it as: "\*!\*@\*blah". From what I understand, it makes your entire second alias completely obsolete.

My answer was equally related to your 'claim' as your 'claim' was related to mine.
I say I want A and B and you pick out B and ignore A.

$fline() has nothing to do with the looping.
It was 1000 times a $fline() search for the same line.
The loop was there to get a benchmark reading with a higher resolution.
You should better exercise yourself in reading what people want.

  var %i = 1 | window -h @yay | while (%i < 1001) { aline @yay a r g %i v 0 | inc %i }
  var %t = $ticks, %i = 1
  while (%i < 1001) {
    var %rec = $fline(@yay,& & & 500 & &,1).text
    rline @yay 500 $puttok(%rec,500,4,32)
    inc %i
  }
  window -c @yay
  return $calc($ticks - %t)
}

you find that:
Hash: 94 @window: 328

So much for faster, again.

So much for keeping its order.
It was brought up earlier in this topic.
Someone already mentioned this drawback.
I confirmed it as relevant.

Are you a politician or so?
You seem to exhibit the same 'features'.
A magnifying glass that makes you miss the bigger picture and blind for the obvious.
Btw, the results here gave Hash: 220 @window: 480

Conclusion?
You ignore selectively the requirements I gave.
First you changed the case to usage of /filter alone.
Here you limited the case to not keep order.
What next?

[quote=argv0]
edit: PS. I won't even bother deciphering your second example, but your initial statement is also wrong there. /filter can deal with strings like "*!*@*blah".. use the -g switch to make the matchtext a regular expression and then write it as: "\*!\*@\*blah". From what I understand, it makes your entire second alias completely obsolete.

About all mIRC's search commands support regex.
Glad you assumed I didn't know that.
Glad you didn't bother to think one step further.
Glad you didn't bother to read the url to the other topic abit, instead of wildly chopping around with an axe.
You might have had an idea why I didn't see regex as an option.

But that's a notdone eh?
Baffling around is so much easier - even more - it looks like it's your goal.

I created a bunch of array snippets that used hash tables to store sorted information.

Whilst they are unsorted by nature, if you just use numbers as key names then you can manage the sort yourself.

For example, if you were to sort this data alphabetically: z b d h j e, it would become: b d e h j z, you could then add each letter to the hash table with a number as key:

Code:
hadd -m table 1 b
hadd -m table 2 d
hadd -m table 3 e
hadd -m table 4 h
hadd -m table 5 j
hadd -m table 6 z


Then:

Code:
echo -a $hget(table,1) = b
echo -a $hget(table,2) = d
echo -a $hget(table,3) = e
echo -a $hget(table,4) = h
echo -a $hget(table,5) = j
echo -a $hget(table,6) = z


And there you have it, sorted hash tables laugh The only thing you need to keep in mind when using this method is that if you were to delete an item you'd have to reshuffle every item after that position so there are no gaps, unless you come up with a decent method to iterate through the table until all items have been found even if there are gaps. This is where the main overhead comes in, it's quite slow to reshuffle 1,000+ items.

Wow someone's getting defensive.

I say I want A and B and you pick out B and ignore A.


To be fair, I didn't *ignore* anything. I ported your alias *command for command* to hash tables. It works exactly the same as your code, does exactly the same thing, and it's faster. So are you going to admit it's faster yet or are you going to cry about a bad experience at McDonalds?

And your point is? That I'm still right? Thanks. Sorry when I tested the code I stepped off the "all computers run at exactly the same speed" planet.

I'm not sure who "confirmed" this (I don't see anyone confirming it here).. Hash tables items are not ordered in memory, yes, but if you practice what you preach and look at the code you'll see that my key names are in fact unique numerical indexes. Do you know what unique numerical indexes do when used as keys? They maintain order. $hget(yay,500) would get line 500, $hget(yay,200) would get line 200, etc.. I'm assuming you didn't actually understand this fact, or you wouldn't have made the above statement. To clarify, my hash table data *is* ordered, just not in your ram. Do you still think I'm wrong?

Huh? I didn't assume anything. I'm responding to your incorrect statement based on what you said here, namely:

This is simply wrong. First of all, they're not considered "false positives" if you incorrectly use a '*' as a literal when you know mIRC will parse it as a wildcard. That's called: using a command incorrectly. If you want to search for a line that contains '*' you use a regular expression match and escape it so it's not treated in a special manner. What exactly was I assuming here? I'm merely telling you that you CAN use /filter to match literal '*'s. Are you still saying you can't? Do you still think I'm wrong?

You don't seem to enjoy factual proof. I'm giving you working code with improved benchmark results that you yourself corroborate and for some reason my giving of this information makes you call me a "politician", which makes no sense to me. Rather than focusing on why my facts may be invalid you're more interested in horrible analogies and trying to insult me by calling me names. Real classy. I'm not sure how else I can convince you...
