  • Passing CMD Results to Variable in a Batch File

    - by TripleNad
    I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.

  • Where does memory dynamically allocated reside?

    - by Summer_More_More_Tea
    Hello everyone: We know that malloc() and new operation allocate memory from heap dynamically, but where does heap reside? Does each process have its own private heap in the namespace for dynamic allocation or the OS have a global one shared by all the processes. What's more, I read from a textbook that once memory leak occurs, the missing memory cannot be reused until next time we restart our computer. Is this thesis right? If the answer is yes, how can we explain it? Thanks for your reply. Regards.

  • Efficient bitshifting an array of int?

    - by nn
    Hi, To be on the same page, let's assume sizeof(int)=4 and sizeof(long)=8. Given an array of integers, what would be an efficient method to bitshift the array to either the left or right? I am contemplating an auxiliary variable such as a long, that will compute the bitshift for the first pair of elements (index 0 and 1) and set the first element (0). Continuing in this fashion the bitshift for elements (index 1 and 2) will be computer, and then index 1 will be set. I think this is actually a fairly efficient method, but there are drawbacks. I cannot bitshift greater than 32 bits. I think using multiple auxiliary variables would work, but I'm envisioning recursion somewhere along the line.

  • Is it faster to count down than it is to count up?

    - by Bob
    Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

  • How determine application subsystem from executable file

    - by Luca
    I'm trying to detect console application from the list of the executables files installed on my computer. How to implement it? Every application has a "subsystem" (windows application, console application or library; specified to the linker as option, I think). How to detect it using only the executable file? Are there alternative methods to detect the application characteristic? Additionally, are there any method for detecting the file is a really executable file? Any issue for JAR executables?

  • Does anybody have practice in programming PCMEF - architectures?

    - by Erkki
    PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

  • [java] Threading socket handler for two sided communication in tcp port

    - by raven
    I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)

  • How to analyse Wikipedia article's data base with R?

    - by Tal Galili
    Hi all, This is a "big" question, that I don't know how to start, so I hope some of you can give me a direction. And if this is not a "good" question, I will close the thread with an apology. I wish to go through the database of Wikipedia (let's say the English one), and do statistics. For example, I am interested in how many active editors (which should be defined) Wikipedia had at each point of time (let's say in the last 2 years). I don't know how to build such a database, how to access it, how to know which types of data it has and so on. So my questions are: What tools do I need for this (besides basic R) ? MySQL on my computer? RODBC database connection? How do you start planning for such a project?

  • Automatically selecting and creating class objects

    - by Omin
    Lets say that we have a box class: class Box { private int width; private int height; //Box Constructor public Box( int height ) { this.height = height; width = 450; } } and a series of Box objects in our main: Box Box1 = new Box(147); Box Box2 = new Box(178); Box Box3 = new Box(784); Is there a way to use a "for" loop to go through these objects? Also, how would you make the computer create class objects for us? eg. create 10 objects using: for( int i=0; i>10; i++) { //method }

  • The conventional location for storing my Java libraries and applications in UNIX based systems

    - by Bytecode Ninja
    I usually store the Java applications and JAR files that I download from the Web in the ~/Java folder on my computer (an OS X machine). I have been doing this since the days when I was a Windows user. However I think in UNIX based systems user local apps are conventionally stored in another directory. I have a feeling that this directory should either be /usr/local/, /usr/local/USERNAME, /opt/local, or /opt/local/USERNAME but I am not sure. Any ideas which directory can I use for this purpose? Please note that, I am talking about archive files that I download from the Web, unpack and use locally and not programs that have installation scripts or MacPorts, etc.

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • MySQL thousands of updates, slowing down.

    - by noryb009
    I need to run a PHP loop for a total of 100, 000 times (about 10, 000 each script-run), and each loop has about 5 MySQL UPDATES to it. When I run the loop 50 times, it takes 3 sec. When I run the loop 1000 times, it takes about 1300 sec. As you can see, MySQL is slowing down ALOT with more UPDATEs. This is an example update: mysql_query("UPDATE table SET `row1`=`row1` +1 WHERE `UniqueValue`='5'"); This is generated randomly from PHP, but I can store it in a variable and run it every n loops. Is there any way to either make MySQL and PHP run at a consistent speed (is PHP storing hidden variables?), or split up the script so they do? Note: I am running this for a development purposes, not for production, so there will only be 1 computer accessing the data.

  • Programming CLI Commands in Program [C / LINUX]

    - by Blackbinary
    I am attempting to make a program in C which presents a GUI and allows the user to select from a list of applications, which to install on the computer. I can manage the gui, but I've never been taught how to actually issue command line commands. I know with bash its just apt-get install firefox for example, but how do I do such a thing with C? i.e. on click, the program runs 'apt-get install The other problem is I'm not familiar with the proper name for this interaction, so it is hard to search. Thanks for the help

  • NSCoding and ostream

    - by Stephen Furlani
    Is there a better way to serialize an ObjC object than using /NSKeyedArchive? I need to distribute the object through a C++ std:ostream-like object to put on another computer. The object has over 122 members of various types... for which wants me to [coder encodeObject: (id) forKey: @"blah"]; for all of them... Does anyone have a nice Perl Script that will at least write it out? I don't even know if the objects it contains implement which means this could turn into a huge ugly mess since I can't change the source of the object - I'll have to inherit & add the @interface to it... Or am I being dumb? Apple's guide doesn't help me since archiving to XML won't pass nicely though the ostream. Is there a better way to do this? -S!

  • Touch Screen Product Catalog for Retail Store

    - by Patrick
    I am a UI/UX designer and I would like to create kiosk type of app that would be a product catalog (help/suggestor) for customers in a retail store using a touch screen monitor (and computer). Something as simple as this: http://www.youtube.com/watch?v=aoH0u6YTTK4 This is what I would like it to do: 1st Screen (Main Menu): Pick a type of category (For example: Dog, Cat, Small Animal) 2nd Screen pick a sub-category of a main category (For example: Puppy, Adult, Senior - DOG) 3rd Screen pick a sub-category of previous sub-category (For example: Food, Healthy, Toys) Then it will display a list of all products with a picture, small description, and price. Thats it. So the point of the kiosk is to help customers find certain products that match their pet criteria. (Dog Puppy Healthy Dog Food) I am wondering what is the best solution: RIA (Flex/Air or Silveright) or flash/action script. I am not sure what is the best technology to use for the following benefits: user-experience (smoothness of touch screen actions) and fast development.

  • Network Communication program in python

    - by lamnep
    Hi all, Basically what I'm trying to achieve is a program which allow users to connect to a each other over a network in, essentially, a chat room. What I'm currently struggling with is writing the code so that the users can connect to each other without knowing the IP-address of the computer that the other users are using or knowing the IP-address of a server. Does anyone know of a way in which I could simply have all of the users scan the IP range of my network in order to find any active 'room' and then give the user a chance to connect to it? Also, the hope is that there will be no need for a central server to run this from, rather every user will simply be connected to all other user, essentially being the server and client at the same time.

  • how to get the exact mouse click position with support for variable screen resolution ?

    - by javadahut
    I'm writing a simple macro program: you record your mouse or keyboard movements, you save the file, and the program will run it for you on your pc computer. however, the situation is, what if the file is run on a laptop where the resolution is smaller? what if the file is to be run on a web server where there is no monitor ? ie) the button is clicked at position (x,y): 300,520 but the button will be at another location in a different monitor resolution. How would you approach this problem ?

  • Eclipse - Ouline View - Turn Off Filtering

    - by Ibolit
    Hi. I recently installed Eclipse on my new computer, and this installation somewhat filters the class members. I think it is somehow related to the Outline, but i couldn't find any settings related to it. The thing is that when i, for example, have an error in a method, and click on the little red square on the margin, eclipse shows me only that method, and nothing else. When i then click on the class name in the outline panel, eclipse shows me the class without import declarations. I can, of course, click on the import declarations in the outline panel, but then i get only them. When I want to jump to the declaration of some method by command-clicking that method's name, I again get only that method on the screen. It is really annoying. Can anyone please help me fix it? Best regards,Timofey.

  • Automator / AppleScript to process incoming emails in Mac Mail

    - by mark
    Hello all, I'm designing an app that allows users to email me crash reports if my app ever crashes. I'd like to leave Mac Mail running on a computer and when an email comes through, an automator script / AppleScript runs to process the contents of the body of the email. I've got the entire parsing/processing done in a python script, except I have to manually copy the contents of the email into a file and then run my parser on that file. What's the best way to set this up so I can the contents of the email be pushed into my parsing script? Many thanks!

  • Why won't Heroku accept my Gemfile.lock in Windows?

    - by mranders
    I have a rails application that I deploy on Heroku. I'm using several different machines, and I noticed that when I add new dependencies (so that Gemfile.lock is rebuilt) and do bundle install on my Windows computer at home, push to Heroku fails with the following error: Unresolved dependencies detected; Installing... Windows Gemfile.lock detected, ignoring it. You have modified your Gemfile in development but did not check the resulting snapshot (Gemfile.lock) into version control ... Gemfile.lock IS under version control, but Heroku appearently chooses to ignore it since it's created in Windows, and then complains that it's missing seconds later. Why does this happen? And how can I solve it?

  • Can Eclipse not hard-code ECLIPSE_HOME when exporting build.xml?

    - by stevex
    I have an Eclipse project that I'm attempting to set up to build both with Eclipse and externally with Ant. It seems like a good way to do this is to have Eclipse generate a build.xml file that I can then use with ant. I'd like to set it up so the build.xml can be regenerated from Eclipse whenever the need arises, which means no hand-editing the build.xml file. But Eclipse writes one entry in there that has a hard-coded path to a directory on my computer, which makes it unsuitable for checking in to a source repository. Specifically it's this entry that's the trouble: <property name="ECLIPSE_HOME" value="D:/Eclipse/Eclipse Galileo (3.5) SR1"/> Is there some way to have Eclipse not output this line, or to make it a relative reference or something that makes sense to check in?

  • What did they program this toy with?

    - by Trix
    A rather strange question: I'm often asking myself with what programming languages things were created. I recently found this toy mini computer I played with when I was 13 or so at home. (Note: It is not one of those toy "notebooks", it's really small and came as an extra with a magazine) "Features": Hadware: LCD with a small field of pixels where the games were going on, besides that some stats such as score, highscore etc. Sounds and horrible music when started A really small "keyboard" with a wire Software: At least 14 or so games, from Snake over Tetris and Breakdown to some abomination of a car racing game A calculator Game selecting menu An alarm clock Inside there is a really small circuit board, I don't want to open the thing up now, though. Can you imagine if the games and "Operating System" of this thing where actually programmed using a language? If yes, what language could it be? If not with a programming language, how else was it created?
