• string parse and replace in for loop

  - by reffer

  i have a string that looks like this - "1AL||9CA||34CO||196WY||..." i want to use a for loop or while loop, in which if i have an integer, it should parse this string and delete the value matching that integer. example for above string string = "1AL||9CA||34CO||196WY||..." integer = 34 for ... loop new string = "1AL||9CA||196WY||..." As you can see the integer matched the integer 34 and deleted from one delimeter "||" to th next one. how can i do this?

• Strange behavior of for loop in scheduler_tick

  - by EpsilonVector

  I'm working on Linux kernel 2.4 (homework) and I inserted the following code into the scheduler_tick function: if (unlikely(rt_task(p)) || (p->policy==SCHED_PROD && p->time_ran>=p->process_expected_time)) { /* * RR tasks need a special form of timeslice management. * FIFO tasks have no timeslices. */ if ((p->policy == SCHED_RR || /*change*/p->policy==SCHED_PROD) && !--p->time_slice) { /*changes*/ if (p->policy == SCHED_PROD){ for (i=0; i<5000; i++){ printk("I'm leeching off SCHED_RR code! %d\n", i); } } /*end changes*/ The addition was added for debugging purposes. For some reason this causes very weird behavior: when a SCHED_PROD process triggers this code (and consequently the loop that follows) the loop counts to about 4600 normally, but then goes back to 4600 each time it counts to 4800, and gets stuck in an infinite loop. What's going on?? EDIT: The i variable is my own.

• Bash loop command until file contains n duplicate entries (lines)

  - by Andrew

  Hello, I'm writing a script and I need to create a loop that will execute same commands until file does contain a specified number of duplicate entries. For example, with each loop I will echo random string to file results. And I want loop to stop when there are 10 lines of of the same string. I thought of something like while [ `some command here (maybe using uniq)` -lt 10 ] do command1 command2 command3 done Do you have any idea how can this problem be solved? Using grep can't be done since I don't know what string I need to look for. Thank you for your suggestions.

• Erlang message loops

  - by Roger Alsing

  How does message loops in erlang work, are they sync when it comes to processing messages? As far as I understand, the loop will start by "receive"ing a message and then perform something and hit another iteration of the loop. So that has to be sync? right? If multiple clients send messages to the same message loop, then all those messages are queued and performed one after another, or? To process multiple messages in parallell, you would have to spawn multiple message loops in different processes, right? Or did I misunderstand all of it?

• border highlighting loop with jquery

  - by Tek

  I'm having trouble coming up with a loop that changes the border color of an image from black to yellow and yellow to black over x seconds. Then applying an interrupt to the loop when the image gets clicked on. I don't know where to start, can someone point me in the right direction? I think I may be using the wrong tools to properly write this. Here's what I've come up so far, though if there's a better way to write this, do share! for( i = 100; i >= 0; i--) { $("#imgid").css("border-color", 'rgb(' + i + '%,' + i + '%,0)'); } I'm having trouble picturing how I could combine two loops so that I can also count upwards as well so that it will turn into yellow and back to black. I also don't know how to go about controlling the amount of time it takes for that loop to execute and creating an interrupt when #imigid is clicked. Which is where I'm not sure how to write.

• Write the longest possible loop.

  - by Abhay

  Hello Group, Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...) I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite. Anyone here; knows how to analyse / attack this problem. P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer. Thanks in advance,

• a nicer way to create structs in a loop

  - by sandra

  Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

• Breaking from for loop in MATLAB GUI

  - by Nick

  I have a for loop in the opening function of a GUI in MATLAB and I'm trying to use a callback button to break the loop. I'm new to MATLAB. Here's the code I have: %In the opening function of the GUI handles.stop_now = 0; for i=1:inf if handles.stop_now==1 break; end end % Executes on button press function pushbutton_Callback(hObject, eventdata, handles) % hObject handle to end_segmenting_button (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) handles.stop_now=1; guidata(hObject, handles); For some reason, despite defining the variables with handles, the loop doesn't break upon pressing the button. Anyone know what's going on? Thanks.

• PHP Casting as Object type in foreach Loop

  - by Coulton

  Within the following code, $quiz_object->personalities contains an array of Personality() objects. // Loop through each personality that exists for the quiz foreach($quiz_object->personalities AS $existing_personality) { // Show all of the existing personalities echo $existing_personality->GetQuizMakerPersonalityHTML(); } How do I "cast" (I think that's the right word) my variable $existing_personality within the foreach loop as the object type? I wish to do this so that when I type $existing_personality->, I get the list of public functions available for that object type. At the moment, Zend doesn't know that it refers to a Personality object within the loop.

• How to improve the speed of a loop containing a sqlalchemy query statement as conditional

  - by LtPinback

  This loop checks if a record is in the sqlite database and builds a list of dictionaries for those records that are missing and then executes a multiple insert statement with the list. This works but it is very slow (at least i think it is slow) as it takes 5 minutes to loop over 3500 queries. I am a complete newbie in python, sqlite and sqlalchemy so I wonder if there is a faster way of doing this. list_dict = [] session = Session() for data in data_list: if session.query(Class_object).filter(Class_object.column_name_01 == data[2]).filter(Class_object.column_name_00 == an_id).count() == 0: list_dict.append({'column_name_00':a_id, 'column_name_01':data[2]}) conn = engine.connect() conn.execute(prices.insert(),list_dict) conn.close() session.close() edit: I moved session = Session() outside the loop. Did not make a difference.

• String loops in Python

  - by Steve Hunter

  I have two pools of strings and I would like to do a loop over both. For example, if I want to put two labeled apples in one plate I'll write: basket1 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit1 in basket1: basket2 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit2 in basket2: if fruit1 == fruit2: print 'Oops!' else: print "New Plate = %s and %s" % (fruit1, fruit2) However, I don't want order to matter -- for example I am considering apple#1-apple#2 equivalent to apple#2-apple#1. What's the easiest way to code this? I'm thinking about making a counter in the second loop to track the second basket and not starting from the point-zero in the second loop every time.

• C++: Allocation of variables in a loop

  - by Rosarch

  Let's say I have a loop like this: vector<shared_ptr<someStruct>> vec; int i = 0; while (condition) { i++ shared_ptr<someStruct> sps(new someStruct()); WCHAR wchr[20]; memset(wchr, i, 20); sps->pwsz = wchr; vec.push_back(sps); } At the end of this loop, I see that for each sps element of the vector, sps->pwsz is the same. Is this because I'm passing a pointer to memory allocated in a loop, which is destructed after each iteration, and then refilling that same memory on the next iteration?

• Can't subtract in a for loop in C/Objective-C

  - by user1612935

  I'm going through the Big Nerd Ranch book on Objective-C, which takes you through some early C stuff. I've played with C before, and am pretty experienced in PHP. Anyhow, I'm doing the challenges and this one is not working the way I think it should. It's pretty simple - start at 99, loop through and subtract three until you get to zero, and every time you get a number that is divisible by 5 print "Found one." Pretty straightforward. However, subtracting by three in the for loop is not working #include <stdio.h> int main (int argc, const char * argv[]) { int i; for(i = 99; i > 0; i-3){ printf("%d\n", i); if(i % 5 == 0) { printf("Found one!\n"); } } return 0; } It creates and endless loop at 99, and I'm not sure why.

• Remote Desktop failed logon event 4625 not logging correctly on 2008 Terminal Services server

  - by Zone12

  When I use the new remote desktop with ssl and try to log on with bad credentials it logs a 4625 event as expected. The problem is, it doesn't log the ip address, so I can't block malicious logons in our firewall. The event looks like this: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-Security-Auditing" Guid="{00000000-0000-0000-0000-000000000000}" /> <EventID>4625</EventID> <Version>0</Version> <Level>0</Level> <Task>12544</Task> <Opcode>0</Opcode> <Keywords>0x8010000000000000</Keywords> <TimeCreated SystemTime="2012-04-13T06:52:36.499113600Z" /> <EventRecordID>467553</EventRecordID> <Correlation /> <Execution ProcessID="544" ThreadID="596" /> <Channel>Security</Channel> <Computer>ontheinternet</Computer> <Security /> </System> <EventData> <Data Name="SubjectUserSid">S-1-0-0</Data> <Data Name="SubjectUserName">-</Data> <Data Name="SubjectDomainName">-</Data> <Data Name="SubjectLogonId">0x0</Data> <Data Name="TargetUserSid">S-1-0-0</Data> <Data Name="TargetUserName">notauser</Data> <Data Name="TargetDomainName">MYSERVER-PC</Data> <Data Name="Status">0xc000006d</Data> <Data Name="FailureReason">%%2313</Data> <Data Name="SubStatus">0xc0000064</Data> <Data Name="LogonType">3</Data> <Data Name="LogonProcessName">NtLmSsp</Data> <Data Name="AuthenticationPackageName">NTLM</Data> <Data Name="WorkstationName">MYSERVER-PC</Data> <Data Name="TransmittedServices">-</Data> <Data Name="LmPackageName">-</Data> <Data Name="KeyLength">0</Data> <Data Name="ProcessId">0x0</Data> <Data Name="ProcessName">-</Data> <Data Name="IpAddress">-</Data> <Data Name="IpPort">-</Data> </EventData> </Event> It seems because the logon type is 3 and not 10 like the old rdp sessions, the ip address and other information is not stored. The machine I am trying to connect from is on the internet and not on the same network as the server. Does anyone know where this information is stored (and what other events are generated with a failed logon)? Any help will be much appreciated.

• Windows server reboot loop - uninstalling hotfixes

  - by Jack

  After installing 3 updates, my system is stuck in a reboot loop. I am using server 2008 r2. I have tried deleting pending.xml from the windows directory, so pelase don't suggest that. I tried dism /image:d:\ /cleanup-image /revertpendingactions which completed successfully but did not solve my issue I then tried: dism /image:d:\ /Remove-Package /PackageName: and sucusfully removed one of the 3 updates. The two updates that are left are not listed with the dism get-packages command, but are listed with the get-apppatches command. I cannot find a way to uninstall them with dism however. So my question is, how can I manually uninstall specific updates or hotfixes from within the winre environment?

• Windows 7 installation reboot loop

  - by Auswoolf

  Upgrading from Vista home premium to win 7 hoe premium from DVD ex Digital river on gigabyte VM900m; core 2 duo 2.13GHz 2GB ram; Western digital 250GB HD. Got as far as "Expanding Windows files ...100% the error message "Computer encountered unexpected error... To install windows press OK to restart computer and reinstall windows" The computer then reboots, loads Windows 7 (new logo) a essage that says "setup is starting services" then the error message comes back. I can get into BIOS to change boot priority but the computer just ignores this and goes through the same sequence. At the point of "to boot from CD/DVD press any key" my keyboard is deactivated and i cannot make a choice and the sae sequence occurs. I cannot break the sequence - I have push every key, disconnected every external device including HDMI screen, but nothing stops the loop. Any ideas? Auswoolf

• How to ensure full path in Windows batch FOR loop

  - by palswim

  I've created a generic batch (or Windows Command) file that lets me loop through the contents of a directory and call a command for each item. IF a%1==a ( set _DIR="%CD%") ELSE ( set _DIR="%~1") IF a%2==a ( set _COMMAND=rem) ELSE ( set _COMMAND=%2) IF a%3==a ( set _FILTER=*.*) ELSE ( set _FILTER=%3) set _OPTS=%4 FOR /F "delims=" %%f IN ('dir %_DIR%\%_FILTER% %_OPTS% /b') DO ( %_COMMAND% "%%f" ) But, I'm trying to determine how to ensure that I call %_COMMAND% on the correct file. I've tried pre-pending the directory variable onto the front, like %_COMMAND% %_DIR%\"%%f", but this leaves a quotation mark in the parameter I pass. For example, if I call my batch file exec_dir.bat, and call it with the following echo_test.bat, I see that all of the files have a quotation mark when echo_test.bat runs. echo %~dpn1.mp4 That batch script produces: > exec_dir.bat "C:\Users\User\Desktop\Test Folder" echo_test.bat *.txt C:\Users\User\Desktop\Test Folder\"Test File.txt C:\Users\User\Desktop\Test Folder\"Test2.txt My thought is that it has something to do with the \ as an escape character, but I can't seem to work around it.

  I have setup a small Sharepoint 2010 deployment and it is working fine, for now. I have run through one of the more popular step by step guides to mail enable the install and what I have is internal and external mail going to my mail enabled list hitting my Exchange 2010 server (on another Win2k8R2 box) and sitting in the submissions queue with a Loop Detected error and they progres no further. Everything appears OK as per the guide. I have setup an SMTP role on the Sharepoint box, as per the guide. I have setup a new Send Conenctor on the Exchange 2010 server, as per the guide. Any ideas on troubleshooting here?

• Reboot loop after Windows XP Service Pack 3 update

  - by espais

  Recently I upgraded to Service Pack 3, and now it seems that something has gone terribly wrong with the update. After logging in, my computer will blue screen after about 5 minutes and then go into a reboot loop (I don't have the exact error message handy). I have a Sager NP2092 notebook, running an Intel chipset. I'd rather avoid having to reformat my XP, especially with my copy of Windows 7 arriving right around the corner. After doing some Googling, I came across this article: Does your AMD-based computer boot after installing XP SP3? However, it deals with the AMD chips, and specifically states not to use its fix on Intel based systems. EDIT After killing the reboot, this is the error that pops up: STOP: 0x000000F4 (0x00000003, 0x8A187118, 0x8A18728C, 0x80604438) EDIT2 I have run Memtest86, and it reported 0 errors.

• Protect foreach loop when empty list

• Windows 7 reboot loop on startup

  - by blade5

  Hi, I am running Windows Server 2008 Datacenter X64 on my server at home. It's using Hyper-V so I have several VMs. All apart from one are Windows Server 2008-based. The other is Windows 7 Ultimate x64 and it was rebooting in a loop when at the login screen. Afterwards, I installed Windows Updates on this VM and now, because after the login, Windows comes up with the text "now configurating, do not restart your PC" before the login screen, I cannot get past this screen because the VM is constantly rebooting so this configuring step does not get completed. So I cannot login. Will an upgrade reinstall of Windows 7 fix this? It seems that the problem is with the system on the VM (system files/updates etc, as opposed to the apps I have installed). Thanks
