• JRE not running correctly on Windows 7 64Bit

  - by dkt91

  An application called DBGL (DosBox Game Launcher) requires JRE in order to run successfully. I had it installed and running on my old Windows 7 32Bit machine without any problems. Today I got my new PC with Windows 64Bit and I cannot get it running anymore. If I install the latest JRE 32Bit version to the \Program Files (x86) folder DBGL says it needs the latest JRE version in order to run and doesn't start. If I install the latest JRE 64Bit version to the \Program Files folder I do not get an error message anymore but the application doesn't start either. Clicking it has literally no effect. Right now I have both JRE versions running parallely and I get the same result I have when only the 64Bit version is installed. Thanks in advance!

• How to automate slipstream?

  - by Gregory MOUSSAT

  Since years I use slipstreamed Windows installations. This works very well, but preparing them is tedious : 1 - install a Windows with the last slipstreamed version we have (automated install) 2 - check Windowsupdate to see what's new, and take note 3 - download each new update available 4 - go to step 2 until no new update is available 5 - slipstream them into the last version we have (I already automated this step) I'd like a way to automate parts or all of this. Maybe a program able to know which updates are installed (already saw one, I don't remember which, and I know PowerShell can do this)... and able to download them ? Or to get them from local disk ? So the steps become : 1 - install a Windows with the last slipstreamed version we have (automated install) 2 - use Windowsupdate until no new update is available (any way to automate ?) 3 - use the magic program 4 - slipstream

• How do networking ports work? Can I configure the ports that client and server use?

  - by joedotnot

  Let's say i have a "server" program listening on address 1.2.3.4:69 (i.e. remote port 69) When i connect from a "client" program to it, typically i would specify the IP address + port of the target or server system; But what port would the client be using ? And how does the server know which port to connect back to the client on? I understand this question is very general, but just wanting to get a general feel for how things work. Then extending this to a specific protocol, say FTP (typical port 21), can I change it such that the server uses port 69, but the client uses port 100? And similarly, for Remote Desktop in WinXP (typical port 3389), i know how to change the server port to be something other than 3389, but how does one change what port the client uses (if at all possible)?

• Outsource SEO - A Strong Business Case

  Outsourcing became quite popular in the 1990's as companies raced to reduce costs by moving non-essential functions out of the corporate cost structure. One of the main methods for doing this was to outsource. The basic business case to move any function to a subcontract was quite simple. Subcontractors that focus only on one thing have probably developed a deeper technical understanding of the process and are more effective. Economies of scale allow the outsourcer to provide the same (or higher quality) service at a lower price.

• Can I find the session ID for a user logged on to another machine?

  - by Dan

  I want to open an application on another computer on the same network via the command line. The scenario here is that the user is in a room surrounded by about 20 computers and wants to be able to launch the same app on every computer without walking from screen to screen opening it up on each individual machine. I've discovered that I can get the basic functionality for this using PsExec as follows: psexec \\[computer] -u [username] -p [password] -d -i [SessionID] [program] For computer, username, password, and program, I'm good. Does anyone know of a way I can figure out which SessionID is assigned to a particular user logged on to a particular machine on the network? Alternately, is there a better way to go about what I'm trying to accomplish?

• UnsatisfiedLinkError: no swt-gtk-4233

  - by Abogical

  I'm a Java newbie who just a made a simple Java program using SWT for GUI via eclipse Juno. The code was working and the program was able to run inside eclipse, so I compiled it and made it a runnable jar file so it can be run outside eclipse. I tried to run it using the terminal and this error came up. Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-gtk-4233 in java.library.path no swt-gtk in java.library.path Can't load library: /home/abody/.swt/lib/linux/x86_64/libswt-gtk-4233.so Can't load library: /home/abody/.swt/lib/linux/x86_64/libswt-gtk.so at org.eclipse.swt.internal.Library.loadLibrary(Library.java:331) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:240) at org.eclipse.swt.internal.C.<clinit>(C.java:21) at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java:63) at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java:54) at org.eclipse.swt.widgets.Display.<clinit>(Display.java:133) at Class1.main(Class1.java:12) So now it looks like it can't find "libswt-gtk-4233.so" and the other file. However, when I took a look at he ".swt" folder I had an "libswt-gtk-3740.so" not 4233. So its trying to find a file that is more up-to-date. So what does that mean, should I update SWT? what's going on?

• Python: how to calculate data received and send between two ipaddresses and ports [closed]

  - by ramdaz

  I guess it's socket programming. But I have never done socket programming expect for running the tutorial examples while learning Python. I need some more ideas to implement this. What I specifically need is to run a monitoring program of a server which will poll or listen to traffic being exchange from different IPs across different popular ports. For example, how do I get data received and sent through port 80 of 192.168.1.10 and 192.168.1.1 ( which is the gateway). I checked out a number of ready made tools like MRTG, Bwmon, Ntop etc but since we are looking at doing some specific pattern studies, we need to do data capturing within the program. Idea is to monitor some popular ports and do a study of network traffic across some periods and compare them with some other data. We would like to figure a way to do all this with Python....

• Dreamweaver not connecting RDC

  - by thomas

  I am trying to use Dreamweaver to Remote Desktop Connect into a computer where a website is hosted. Normal traffic to this server is routed to another domain, but when accessed by IP (it is my understanding) the traffic never hits any sort of nameserver request, and so stays there. This server is set up so that the only way I can access it is RDC. I can connect using an RDC program, but when I attempt to use Dreamweaver, I get a vague error. The desired action could not be completed because an unexpected client/server communication error occurred. I have Web URL as http://my.ip.number/directory And in the settings panel, I have Host name: my.ip.number Port: 3388 Host directory: C:\Program Files (x86)\directory/directory Username: user Password: ••••••• What could be preventing Dreamweaver form connecting? Thanks! SERVER DETAILS It is a virtual server Windows SERVER 2008 R2 Standard Service Pack 1

• Terminal Server Spoolsv.exe error

  - by Voyager

  We are having a terminal server ibm x3650 with 8 gb of RAM. On many occasions, at least once in a day, we get the error "The instruction at "0x7c8199b2" refrenced memory at "0x9ddc2ade". The memory could not be "read". Click OK to terminate the program. Click on CANCEL to debug the program. I have surfed very many sites, microsoft included, but none of them have been able to give conclusive solution for ending this problem. When we press on ok or cancel, then our ERP application (VB-MS SQL) starts to work normally. till such time the message is there, all our reports are hanged (Business Objects reports). We have already installed all the drivers of printers on the TS. Can anyone help?

• Help looking before I leap! I need expert guidance...

  - by Ellen Reddick

  27" iMac running win7 under bootcamp (slick! ). I have Access 2003 program with files linked through ODBC used by 4 installations (all with Access 2003 installed). I want to buy Access 2010 and try it under virtual PC (under Bootcamp). Will it work (since I have to install the ODBC drivers)? If I decide after this trial that I like what it does, can I then install it under the Windows 7 bootcamp partition (with or without uninstalling the virtual PC) without using up the 2nd allowed installation? Also, I see that MS allows an Office Pro 2010 trial download good for 60 days. Would this work in Windows 7 Virtual PC and would it be a better way to go, followed by a legitimate purchase of Access 2010 for the Windows 7? This is not an Access programming question--I realize there may be some tweaks necessary in the program to run it under 2010 and I can handle that part.

• How to change the download save directory in ktorrent from a remote host

  - by Garethj94

  So I have ktorrent running on a server and I don't have the ability to see the X11 display for the client, and I need to change my download directory since I like to keep everything very organized. So I need a way to change the download directory for the program as a whole, not like decide where to put each and every torrent that I download. This can't be done through the webui preferences so I'm guessing that I'll have to do it through ssh somehow but from what I've read there really isn't a command to use. Also the way that I have the application run is on startup my server runs the command ktorrent, so it will already be running when I want to change the download location so I assume that I will have to restart the program as well. If anyone knows how to do this it would be much appreciated, and I can't think that I'm the only person to want this feature.

• Research useful for getting a job?

  - by Twirling Hearth

  I have recently started a BS program in Computer Science, in order to improve my employment prospects. I already possess a Master's in sociology (as part of a PhD program that I left early because I could not possibly sustain interest any longer). As such, I am trying to find my way in the grand world of computers. One option that has been suggested to me in the past is something to do with social networking. I already have a strong social sciences background, and my knowledge of programming is increasing as I go through my studies. I know there are some people in my city (Boston) who are doing research in that area, so it's possible I could get someone to take interest in me. For that matter, because research is something that I'm pretty good at, it's an option I'm considering, career-wise. I just have one question, is it a worthwhile use of my time career-wise? I have no burning intellectual passion for that topic, but I'm perfectly happy to do it, if it means $$$. Your thoughts are welcome.

• How can I deal with the cargo-cult programming attitude?

  - by Aivar

  I have some computer science students in a compulsory introductory programming course who see programming language as a set of magic spells, which must be cast in order to achieve some effect (instead of seeing it as a flexible medium for expressing their idea of solution). They tend to copy-paste code from previous, similar-looking assignments without considering the essence of the problem. Can anyone recommend some exercises or analogies to make these students more confident that they can, and should, understand the structure and meaning of each piece of code they write?

• Shell script to read value from a file and compare it to another one

  - by maneeshshetty

  I have a C program which puts one unique value inside a test file (it would be a two digit number). Now I want to run a shell script to read that number and then compare with my required number (e.g. 40). The comparison should deliver "equal to" or "greater". For example: The output of the C program is written into the file called c.txt with the value 36, and I want to compare it with the number 40. So I want that comparison to be "equal to" or "greater" and then echo the value "equal" or "greater".

• How to quickly search through a very large list of strings / records on a database

  - by Giorgio

  I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

• How to combine wildcards and spaces (quotes) in an Windows command?

  - by Jan Fabry

  I want to remove directories of the following format: C:\Program Files\FogBugz\Plugins\cache\[email protected]_NN NN is a number, so I want to use a wildcard (this is part of a post-build step in Visual Studio). The problem is that I need to combine quotes around the path name (for the space in Program Files) with a wildcard to match the end of the path. I already found out that rd is the remove command that accepts wildcards, but where do I put the quotes? I have tried no ending quote (works for dir), ...example.com*", ...example.com"*, ...example.com_??", ...cache\"[email protected]*, ...cache"\[email protected]*, but none of them work. (How many commands to remove a file/directory are there in Windows anyway? And why do they all differ in capabilities?)

• Game planning and software design? I feel that UML is not convenient

  - by user1542

  In my university, they always emphasize and hype about UML design and stuff, in which I feel it is not going to work well with game structure design. Now, I just want a professional advice on how should I begin my game designing? The story is I have some skill in programming and have done many minor game such as getting some 2D platformer working to some extend. The problems that I find about my program is the poor quality design. After coding for a while, things start to break down due to poor planning (When I add new feature, it tends to make me have to recode the whole program). However, to plan everything out without a single design flaw is a bit too ideal. Therefore, any advice to how should I plan my game? How should I put it into visible pictures, so that me and my friends are able to overview the designs? I planned to start coding a game with my friend. This is going to be my first teamwork, so any professional advices would be a pleasure. Is there any other alternatives than UML? Another question is how does "prototyping" normally looks like?

• An iterator is a section of code that returns an ordered sequence of values of the same type.

  Among other languages, iterators are used in C++, C# and other .NET languages, Java, Ruby, and Python. The primary purpose of an iterator is to allow a user to process every element of a container while isolating the user from the internal structure of the container.  read moreBy Peter BrombergDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Most efficient way to store this collection of moduli and remainders?

  - by Bryan

  I have a huge collection of different moduli and associated with each modulus a fairly large list of remainders. I want to store these values so that I can efficiently determine whether an integer is equivalent to any one of the remainders with respect to any of the moduli (it doesn't matter which, I just want a true/false return). I thought about storing these values as a linked-list of balanced binary trees, but I was wondering if there is a better way? EDIT Perhaps a little more detail would be helpful. As for the size of this structure, it will be holding about 10s of thousands of (prime-1) moduli and associated to each modulus will be a variable amount of remainders. Most moduli will only have one or two remainders associated to it, but a very rare few will have a couple hundred associated to it. This is part of a larger program which handles numbers with a couple thousand (decimal) digits. This program will benefit more from this table being as large as possible and being able to be searched quickly. Here's a small part of the dataset where the moduli are in parentheses and the remainders are comma separated: (46) k = 20 (58) k = 15, 44 (70) k = 57 (102) k = 36, 87 (106) k = 66 (156) k = 20, 59, 98, 137 (190) k = 11, 30, 68, 87, 125, 144, 182 (430) k = 234 (520) k = 152, 282 (576) k = 2, 11, 20, 29, 38, 47, 56, 65, 74, ...(add 9 each time), 569 I had said that the moduli were prime, but I was wrong they are each one below a prime.

• C Language preprocessing doubt

  - by khanna_param

  Hi, There are different kind of macros in C language, nested macro is one of them. Considering a program with the following macro define HYPE(x,y) (SQUR(x)+SQUR(y)) define SQUR(x) (x*x) using this we can successfully complile to get the result. My question:- As we all know the C preprocessor replaces all the occurrence of the identifiers with the replacement-string. Considering the above example i would like to know how many times the C compiler traverses the program to replace the macro with the replacement values. I assume it cannot be done in one go. Thanks.

• Tabbed terminal that connects to a GNU Screen session?

  - by screenuser

  I use the session feature of screen extensively. For example, I'll start a screen session for "project1" as "screen -S project1", and then when I need to reconnect I use "screen -d -r project1". This makes it easy to manage multiple projects, each with their own set of shell sessions. What I would love to do now is that when running on Windows and Linux, to be able to use a tabbed terminal program (such as gnome-terminal) to connect to a screen session and have all of the screen windows split out to separate tabs. This way I get all the usual power of screen, but with the convenience of a richer GUI experience. Is there any such terminal program available on Windows and/or Linux?

• Network card dies when trying to wake up laptop from sleep

  - by Bugmaster

  I have a Dell XPS 1640 laptop (aka Dell Studio XPS 16), running Vista. Whenever the laptop wakes up from sleep, my Broadcomm LAN card immediately dies. Any attempt to access it completely locks up whichever program I use to access it. There appears to be no way to re-awaken the card, other than rebooting; note that Vista does not even shut down properly if some program is waiting for the card. So far, I have tried the following: Disabled the "allow your computer to shut down this device to save power" in the device properties. This had no effect. Attempted to disable and then enable the card in the device properties. No effect. Tried ipconfig /renew: this locks up ipconfig to the point where I can't even kill its process. Force-install updated drivers from broadcomm: no effect. Does anyone have any other ideas ?
