• Delphi 7 - Why does Windows 7 change encoding of characters in runtime?

  - by LukLed

  I have a delphi 7 form: and my code: when I run this form in Windows 7, I see: In design time, form had polish letters in first label, but it doesn't have them in runtime. It looks ok on Vista or Windows XP. When I set caption of second label in code, everything works fine and characters are properly encoded. First 5 codes of top label on Windows 7: 65 97 69 101 83 First 5 codes of top label on Windows Vista/XP: 165 185 202 234 140 First 5 codes of bottom label on every system: 165 185 202 234 140 Windows 7 changes encoding, why? My system settings seem to be ok. I have proper language set for non-unicode applications in control panel.

• How would you go to "design" a cart within a Zend Framework project?

  - by ÉricP

  Hi, I know ZF well, and a little bit of Magento, but I'm new to E-commerce, and I'm sure there are best practice to follow when designing a cart model. How would go to design a cart? I though of two models, Model_Cart and Model_Cart_Item used in conjonction with Zend_Session to store the cart in session. What are your feedbacks? How would you go to do that? What should I know about writing a cart system? Note that I need a simple system, I even don't need to work with quantity

• xCode screensaver with openGL

  - by moka

  Hi, I am currently simply trying to build a simple screen saver in xcode 3.2 on osx 10.6.3 using an openGL view as described in this article: http://cocoadevcentral.com/articles/000089.php anyways even if I use the exact same code from the example all I see when testing the screen saver is a black screen. I looked in OSX Console if it tells me anything useful. the only thing I get is something like this: [0x0-0x1e01e].com.apple.systempreferences[629] System Preferences(629,0x7fff71071be0) malloc: reference count underflow for 0x20057be80, break on auto_refcount_underflow_error to debug. System Preferences[629] invalid context I have no idea what is wrong, so I would be glad if someone could tell me how to use openGL together with the screensaver template in xCode 3.2. Also, is there a way to make another target so I can preview the screensaver from within xCode? Thanks!

• Designing a peer to peer network

  - by Varun

  I am designing a simple peer to peer network. The basic architecture will be as follows: A central server- that keeps track of all the peers. The job of this server is to keep track of all the peers that join the network. Every peer could do things: a. Download a file from it's peer b. Push a file (send a file) to it's peer. Could anybody please tell me what would be the best design for such a system? What would be the problems that i might run into and so on. I am planning to use Java as the programming language to implement. Would it be a good choice? Also, is it necessary that i would need a Linux box to develop the system? or is it fine if i use a Windows machine? Your help will be much appreciated! Thanks!

• Identifying idle state on a windows machine

  - by SaM

  I know about the GetLastInputInfo method but that would only give me the duration since last user input - keyboard or mouse. If a user input was last received 10 minutes ago, that wouldn't mean the system has been idle for 10 minutes - scans, downloads, movies - lots of reasons. So how can we identify whether the system is truly idle or not? Does anyone know what Window's definition of "idle" is? Must be a combination of thresholds - like less than 5% cpu util, less than 3% disk util etc. - along with the user input parameter...anyone knows the exact definition?

• PHP with SQL Injection

  - by Scott S

  For our first assignment in a System Security class, we have to hack into the professors "cheaply organized" sql database. I know the only user is "admin" and the select statement generated in the php is: select user_id from user where user_username = 'admin' AND user_password = md5('noob') I am having a number of problems attempting to bypass the password part of this statement as the professor has some javascript embedded in the page to sanitize the username and password of any non-alphanumeric values. This can be bypassed by turning off javascript :P but any values sent still get cleaned by the operating system (some build of Debian 32-bit). I've seen the code for the login request and it does not escape any characters. How do I bypass the operating systems escape sequences?

• Move/copy files/folder in linux/solaris using only bash built-ins

  - by KullDox

  There was a situation when somebody moved the whole rootdir into a subdir on a remote system, thus all the system tools like cp, mv, etc didn't work anymore. We had an active session though but couldn't find a way to copy/move the files back using only bash built-ins. Do somebody know of a way to achieve this? I even thought about copy the cp or mv binary in the currentdir with while read -r; do echo $LINE; done and then redirect this to a file, but it didn't work. Guess because of all the special non printable chars in a binary file that can't be copied/displayed using echo. thanks.

• EF 4.1 Code First Detaching Entity

  - by Nazaf

  I am trying to add an entity to the DB. Once I have added it, I want to detach it, so I can manipulate the object safely without making any changes to the DB. After calling context.SaveChanges() I do the following to detach the entity: // save context.Stories.Add(story); // attach tags. They already exists in the database foreach(var tag in story.Tags) context.Entry(tag).State = System.Data.EntityState.Unchanged; context.SaveChanges(); context.Entry(story).State = System.Data.EntityState.Detached; However, changing the entity state to DETACHED will remove all related entities associated with the my entity. Is there a way to stop this ? If I don't detach the entity, all my changes are sent to the DB next time I call context.SaveChanges() Thanks!!

• In a virtual machine monitor such as VMware's ESXi Server, how are shadow page tables implemented?

  - by ali01

  My understanding is that VMMs such as VMware's ESXi Server maintain shadow page tables to map virtual page addresses of guest operating systems directly to machine (hardware) addresses. I've been told that shadow page tables are then used directly by the processor's paging hardware to allow memory access in the VM to execute without translation overhead. I would like to understand a bit more about how the shadow page table mechanism works in a VMM. Is my high level understanding above correct? What kind of data structures are used in the implementation of shadow page tables? What is the flow of control from the guest operating system all the way to the hardware? How are memory access translations made for a guest operating system before its shadow page table is populated? How is page sharing supported? Short of straight up reading the source code of an open source VMM, what resources can I look into to learn more about hardware virtualization?

• The operation has timed out

  - by np

  We shave this code which result in timeout when downlaoding the file programatically: System.Net.WebClient Client = new System.Net.WebClient(); if (!File.Exists(fileName)) { Client.DownloadFile(downloadLink, fileName); HtFilesSuccessfullyDownloaded[fileName] = fileName; string SuccessfullyDownloadedFiles = Path.Combine(dirName, "SuccessfullyDownloadedFiles.txt"); File.AppendAllText(SuccessfullyDownloadedFiles, Environment.NewLine + fileName); } It looks like when the files are large we are getting the timeout error when DownloadFile method is called. We have added the followign in web.config but it does not look like it helps: <httpRuntime maxRequestLength="1048576" executionTimeout="3600" /> Please let me know if you have any suggestions.

• How Two Programs Can Talk To Each Other In Java?

  - by Arnon

  My first time here... I want to ?reduce? the CPU usage/ROM usage/RAM usage - in general ?speaking?, all system resources that my App use - how doesn't? :) For this reason i want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which mean, to call the update method(that i wrote) that found in the Main class. How can i call the update method in the Main program from the preferences program? Or in the other hand... There is a way to build preferences window that take system resources just when it's appear? Is this approach - of separating programs and let them talk to each other(somehow) - is a right approach for speeding up my programs? tnx

• Searching for empty methods

  - by Brian McCord

  I am currently working on a security audit/code review of our system. This requires me to check all pages in the system and make sure that the code behind contains two methods that are used to check security. Sometimes the code in these methods get commented out to make testing easier. So, my question is does anyone know an easy way to search code, make sure the methods are present, and to determine which ones have no code or have all the code commented out. It would make my job much easier if I can get a list instead of having to look at every file... I'm sure I could write this myself, but I thought someone may know of something that already exists. Thanks!

When i comment function getWords the function getWordFeature returns non-zero value .But when uncommented , the output is as follows: Word size:15055 Size of arrList:embedWords: 0

• parsing primitive types using java.util.Scanner

  - by Rich Fluckiger

  I'm new to java so forgive the noob question. I have created a swing application that basically has three input strings in JTextFields: loanAmount, interestRate and loanYears and a single submit button with the EventAction. I'm trying to use the java.util.Scanner to parse the input to primitive types that I can use in calculations. I'm getting an error in NetBeans indicating that my variables are not recognized? should I not be calling System.in? private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) { Scanner keyInput = new Scanner(System.in); while (true) try{ double amount = keyInput.nextDouble(loanAmount.getText()); double interest = keyInput.nextDouble(interestRate.getText()); int years = keyInput.nextInt(loanYears.getText()); } catch (NumberFormatException nfe){ } }

• Crystal Report with mutliple row columns.

  - by Jack

  I'm not sure if the title properly explains what I'm trying to do. I'm trying to move from using SQL Reporting Services to a Crystal Reports Web App. I've gotten some reports to design properly because they are simple cross-tab reports that require nothing special. I'm running into a little problem of a user matrix report. Here's how the report looks on SQL Reporting Services: group1 group2 group3 username1 first1 last1 title1 X X username2 first2 last2 title2 X X 2 1 1 Normally in VS2008 with a SQL rdl, I would right click on the row and Insert Column. However, i don't see a way to do this in Crystal Reports. I've tried setting up multiple row groups, but that adds mutliple groupings like: group1 Total ... Username Total ... first Total ... last ...

• How to create wordpress-like option table and get values for each row?

  - by Nacho

  Hi guys. I'm looking to create an options table in my db that makes every record a system option, so I can work with a little number of fields. My db has the following structure: 3 columns named id, name, and value The following data is inserted as an example: +--+-----------+--------------------------+ |id|name |value | +--+-----------+--------------------------+ | 1|uri |www.example.com | | 2|sitename |Working it out | | 3|base_folder|/folder1/folder2/ | | 4|slogan |Just a slogan for the site| +--+-----------+--------------------------+ That way I can include a large number of customizable system options very easily. The problem is that I don't know how to retrieve them. How do I get the value of uri and store it as a var? And better yet, how do I get, for exmaple, values of id 1 and 4 only without making a query each time? (I assume multiple queries are useless and a pretty ugly method.) I know the question is pretty basic but I'm lost here. I'd really appreciate your answer!
