  1. Hi. I'm a teacher and I do a lot of tutorials and other presentations on my computer. I've developed a tool using AutoIt and Adobe AIR to display all the shortcuts I use while I'm presenting. According to the forum rules this would mean that I've developed a keylogger, so I can't show any of the code, but I'm still hoping someone will help me solve an issue I'm having - a memory leak (or at least I think that's it). I can see the application is taking up more and more memory, but it never goes super crazy. I think it was at 25 MB at one point and that was it. However I see that the longer the application is running less responsive it is. It doesn't capture all the events, or it simply lags. I'm using AssocArrays and _MouseOnEvent UDFs, _WinAPI_SetTimer, _WinAPI_SetWindowsHookEx, _Singleton and TCP. I've done some research before posting this and I know there are some issues in special cases, but all solutions were "code specific". Since I can't post any of the code I couldn't respond in those threads. Other than that it really doesn't seem to be the problem with any of the UDFs, so my question is: Is this a memory leak? If so how can I find it and remove it? What to do to avoid it in the future. I understand that declaring variables over and over (something in the timer) may be the cause of this, so according to what I've read on the forum I've changed the variables to Global and moved them outside the functions. That way they are only declared once, and then only values are being reassigned. That unfortuantly didn't help. Is there anything else I could do or look for? BTW - I've used Adobe AIR to create a nice UI. If someone want's to create something similar UEZ was kind enough to share his code of creating such GUI with nice antialiased labels. https://www.autoitscript.com/forum/topic/178366-adobe-air-like-window/#comment-1280587
  2. Hello, I have a problem, I downloaded example of TCP Server and Client, but client doesn't work, It shows TCPConnect 10060 error (timeout), I tried to turn on two servers, I think server work, because one server show 10048 error(Address already in use) I don't know why it doesn't work, I edited that script, but it doesn't work still. I tried TCPConnect and TCPAccept from AutoIt3\Examples\Helpfile, but TCPConnect shows error 10060(timeout)... Anybody knows how to fix it? Thanks ; SERVER #include <Array.au3> TCPStartup() Dim $Socket_Data[1] $Socket_Data[0] = 0 $Listen = TCPListen(@IPAddress1, 1018, 500) If @error Then ConsoleWrite('!-->['&@Hour&":"&@MIN&":"&@SEC&'] TCPListen error.

  3. Hello, if an IP address is not reachable then TCPConnect lasts about 21 seconds for me the return with the error.

  4. Hi. I'm working on a script to "round robin" through a list of Terminal Servers. the PC's host names are like "PC1", "PC2", "PC3", ... at each site, so I just use the "number suffix" to determine, which TS server shall be tried for *THIS* PC first, 2nd, 3rd (done, no problem). The issue is showing up, when a TS-Server is *NOT* available. Setting opt("tcptimeout",50) doesn't speed up the process, but I don't think, this is autoit related: it always takes quite a number of seconds to get the result, also with several other tools I've tried, that make use of the Win network APIs. So I suspect, that it's the Windows TCP/IP stack, that's the constraint (WinXP SP3 and Win7, x86 and x64). Question: Is there some "CMDline single EXE tool" / "some other approach", to get the up / open / closed status for an IP:TCPport pair instantly? nmap.exe is dependant on several files coming with it's installation (so fileinstall() would have to install quite a bunch of files), and it also doesn't return valuable exit codes representing it's results, otherwise fileinstall() and this line would be my friend: nmap -PS 192.168.188.111 -p 3389 There are quite a lot of very fast GUI IP scanning tools, but I couldn't find one for command line (ab-)use so far. Any suggestions appreciated, as I don't want to re-invent the wheel ;-) Regards, Rudi.
