  • Asp.net profile in a separate assembly

    - by Shimrod
    Hi everyone, I have a web application which uses membership and profiles. I successfully used the WebProfileBuilder extension, so my profile class is correctly generated, and is working nicely. However, after a new request of my client, I need now to move that profile management part into another assembly (so I'd be able to get profile information in a windows service running on the same machine). What I made is created the new assembly, moved my generated profile file, and tried to use it from the other assembly, but without any success. I always get a SettingsPropertyNotFoundException. My tought is that the profile system doesn't know where to find its connection information, so I tried to add the connectionstring and provider in the app.config of this assembly, but this doesn't seem to work. What am I missing ? Is it possible to do ? Thanks in advance!

  • Programatically determining file "size on disk" in advance

    - by porkchop
    I need to know how big a given in-memory buffer will be as an on-disk (usb stick) file before I write it. I know that unless the size falls on the block size boundary, its likely to get rounded up, e.g. a 1 byte file takes up 4096 bytes on-disk. I'm currently doing this using GetDiskFreeSpace() to work out the disk block size, then using this to calculate the on-disk size like this: GetDiskFreeSpace(szDrive, &dwSectorsPerCluster, &dwBytesPerSector, NULL, NULL); dwBlockSize = dwSectorsPerCuster * dwBytesPerSector; if (dwInMemorySize % dwBlockSize != 0) { dwSizeOnDisk = ((dwInMemorySize / dwBlockSize) * dwBlockSize) + dwBlockSize; } else { dwSizeOnDisk = dwInMemorySize; } Which seems to work fine, BUT GetDiskFreeSpace() only works on disks up to 2GB according to MSDN. GetDiskFreeSpaceEx() doesn't return the same information, so my question is, how else can I calculate this information for drives 2GB? Is there an API call I've missed? Can I assume some hard values depending on the overall disk size?

  • C# Spawn Multiple Threads for work then wait until all finished

    - by pharoc
    just want some advice on "best practice" regarding multi-threading tasks. as an example, we have a C# application that upon startup reads data from various "type" table in our database and stores the information in a collection which we pass around the application. this prevents us from hitting the database each time this information is required. at the moment the application is reading data from 10 tables synchronously. i would really like to have the application read from each table in a different thread all running in parallel. the application would wait for all the threads to complete before continuing with the startup of the application. i have looked into BackGroundWorker but just want some advice on accomplishing the above. Does the method sound logical in order to speed up the startup time of our application How can we best handle all the threads keeping in mind that each thread's work is independent of one another, we just need to wait for all the threads to complete before continuing. i look forward to some answers

  • Implementing Explosions

    - by Xkynar
    I want to add explosions to my 2D game, but im having a hard time with the architecture. Several game elements might be responsible for explosions, like, lets say, explosive barrels and bullets (and there might be chain reactions with close barrels). The only options i can come up with are: 1 - Having an array of explosions and treat them as a game element as important as any other Pros: Having a single array which is updated and drawn with all the other game element arrays makes it more organized and simple to update, and the explosive barrels at a first glance would be easy to create, simply by passing the explosion array as a pointer to each explosive barrel constructor Cons: It might be hard for the bullets to add an explosion to the vector, since bullets are shot by a Weapon class which is located in every mob, so lets say, if i create a new enemy and add it to the enemy array, that enemy will have a weapon and functions to be able to use it, and if i want the weapon (rocket launcher in this case) to have access to the explosions array to be able to add a new one, id have to pass the explosion array as a pointer to the enemy, which would then pass it to the weapon, which would pass it to the bullets (ugly chain). Another problem I can think of is a little more weird: If im checking the collisions between explosions and barrels (so i create a chain reaction) and i detect an explosion colliding with a barrel, if i add a new explosion while im iterating the explosions java will trow an exception. So this is kinda annoying, i cant iterate through the explosions and add a new explosion, i must do it in another way... The other way which isnt really well thought yet is to just add an explosive component to every element that might explode so that when it dies, it explodes or something, but i dont have good ways on implementing this theory either Honestly i dont like either the solutions so id like to know how is it usually done by actual game developers, sorry if my problem seems trivial and dumb.

  • PDF reader to capture regions

    - by Amitesh
    I need to build an application which can render a pdf document. The application should allow the user to draw rectangles on the pdf to define regions such as Address region, Invoice Number region and so on. The application will need to capture these regions and save them. I already have an application in which I can pass these region information with the pdf and it will get me the text back. My only problem at the moment is that I cannot get the region information from the user. So can anybody please point me to any application which can do the above (allow the user to draw rectangles to capture the regions).

  • Iptables working strangely

    - by user109985
    I have Ubuntu 12.04 x64 installed in my laptop. I'm quite new to linux, and I wanted to specify certain rules for the iptables firewall. This is the saved config of my iptables: *mangle :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] COMMIT *nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A PREROUTING -p tcp -m tcp --dport 3306 -j DNAT --to-destination 192.168.1.100:3306 -A PREROUTING -p tcp -m tcp --dport 11002 -j DNAT --to-destination 192.168.1.100:11002 -A PREROUTING -p tcp -m tcp --dport 13000 -j DNAT --to-destination 192.168.1.100:13000 -A PREROUTING -p tcp -m tcp --dport 13001 -j DNAT --to-destination 192.168.1.100:13001 -A PREROUTING -p tcp -m tcp --dport 13002 -j DNAT --to-destination 192.168.1.100:13002 -A PREROUTING -p tcp -m tcp --dport 13003 -j DNAT --to-destination 192.168.1.100:13003 -A PREROUTING -p tcp -m tcp --dport 13004 -j DNAT --to-destination 192.168.1.100:13004 -A PREROUTING -p tcp -m tcp --dport 13061 -j DNAT --to-destination 192.168.1.100:13061 -A PREROUTING -p tcp -m tcp --dport 13099 -j DNAT --to-destination 192.168.1.100:13099 -A POSTROUTING -j MASQUERADE COMMIT *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT COMMIT In theory, what it does is to drop all connections in all ports except for http, mysql and few other ports. Moreover, it redirects all mysql and 13000-13004..etc port connections to a specific local ip in the same port, which is 192.168.1.100. But what I find strange is that when my firewall is active, it blocks absolutely all the input connections, even those which must not block (http, mysql). In fact, I'm literally blocked and I can't establish any external connection. What am I doing wrong? PS: I tested the firewall without those redirections, and it still block all inputs, so I suppose it's not the problem.

  • Web Designer looking to learn back-end programming...

    - by Tabetha Moe
    Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

  • list all functions on CRAN

    - by baptiste
    Suppose I'm trying to run a script of unknown origin, and one of the functions is from a package that is not loaded by the script (an oversight, maybe it was loaded in the .Rprofile of the person who wrote it). How can I find in which package this function resides? There's some information compiled on CRAN, that doesn't require the user to download/install all R packages locally; however as far as I could tell it only gives access to the DESCRIPTION files. RSiteSearch, and its web equivalent, seem to access an online database of all CRAN packages, where presumably a list of all functions would be available. Is there some way of accessing this information? Thanks. Edit: I know sos::findFn, utils::RSiteSearch and search.r-project; what I would like is to get the raw data that these tools use.

  • How can I compress jpeg images in Java without losing any metadata in that image?

    - by guitarpoet
    I want compress jpeg files using Java. I do it like this: Read the image as BufferedImage Write the image to another file with compression rate. OK, that seems easy, but I find the ICC color profile and the EXIF information are gone in the new file and the DPI of the image is dropped from 240 to 72. It looks different from the origin image. I use a tool like preview in OS X. It can perfectly change the quality of the image without affecting other information. Can I done this in Java? At least keep the ICC color profile and let the image color look the same as the origin photo?

  • Locking DB w/ Large Reads (Ruby-on-Rails/Heroku)

    - by Splashlin
    Currently I have a Web API running on Heroku that is constantly writing information we're collecting from other data sources (currently theres about half a GB of data and it's growing very quickly). We're looking to add a reporting system on top of the current database that we can use to extract useful information out of the DB. The problem is that when we're running reports we're locking the DB and any other sites communicating with the DB are timing out. Does anyone have any solutions on how to solve this type of issue? Amazon RDS seems to have some interesting stuff with database replication but I don't know if that will solve my problems. Any advice would be greatly appreciated. Thanks

  • [SQL] Getting the sum of several columns from two tables

    - by romaintaz
    I want to get the sum of several columns from 2 different tables (these tables share the same structure). If I only consider one table, I would write this kind of query: SELECT MONTH_REF, SUM(amount1), SUM(amount2) FROM T_FOO WHERE seller = XXX GROUP BY MONTH_REF; However, I would like to also work with the data from the table T_BAR, and then have a select query that return the following columns: MONTH_REF SUM(T_FOO.amount1) + SUM(T_BAR.amount1) SUM(T_FOO.amount2) + SUM(T_BAR.amount2) everything grouped by the value of MONTH_REF. Note that a record for a given MONTH_REF can be found in one table but not in the other table. In this case, I would like to get the sum of T_FOO.amount1 + 0 (or 0 + T_BAR.amount1). How can I write my SQL query to get this information? For information, my database is Oracle 10g.

  • Interactive Charts for web application

    - by user227290
    We are working on a web based application (implemented in JAVA) on commodity prices and one part of it is interactive charting. I provide a simplified example here. We have a table in Mysql database where we have information on commodity prices in US states and counties. One aspect of the application is to create interactive plots based on user choice. For example, if the user needs to see the price density in Oregon and Linn county then she chooses it from the menu in a webpage and it is rendered on fly with accompanying quantile information in a table. As the user changes state and county these plots and table change on fly.For our computational need we are using R (and use rjava to integrate it to our web application) and I know that if interactivity is not an issue this is a piece of cake in ggplot2, but I am not aware of any interactive version of R graphics framework (like lattice, ggplot2). We are exploring google visualization API but I am not sure we can have the statistical power we need in some of the plots.Please help.

  • What is the best way to restore(rollback) data in an application to a specified state(date) ?

    - by panzerschreck
    Hello, An example would set the context right, the example below captures the various states of the entity, which needs to be reverted(rolled back) . State 1 - Recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 State 2 - Recorded on 02-Mar-2010 Column1 Column2 Data1 0.57 State 3 - Recorded on 03-Mar-2010 Column1 Column2 Data1 0.58 User notices that state3 is not what he intended to be in, decides to revert back to state2. One approach that I can think of, without modifying the entity is via "auditing" all the inserts/updates, as below, the rollback information captures the data just before the updates/modifications on the entity, so that it can be applied in an order when you need to revert.Please note that changing the entity's schema, is not an option. Rollback - R1 recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R2 Recorded on 02-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R3 Recorded on 03-Mar-2010 Column1 Column2 Data1 0.57 So, to get to state2 , we would start with rollback information R1,apply R2 onto it. Is there a better approach to achieve this ? Thanks for your time.

So I tried following the instructions given at http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users but I cannot get it to work for me. Is there a step-by-step guide that I can follow to get this to work for me? Also, once I have added these custom fields, I would obviously need to add / edit / delete data from them. I cannot seem to find any instructions on how to do this.

  • Sending a Java object from my Android phone to my Computer

    - by TehGoose
    Hi, I was wondering what the simplest program for sending an object from my Andriod phone to my computer wirelessly (via LAN) would be. I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start. What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me. Could anyone help me out?

  • Database/NoSQL - Lowest latecy way to retreive the following data...

    - by Nickb
    I have a real estate application and a "house" contains the following information: house: - house_id - address - city - state - zip - price - sqft - bedrooms - bathrooms - geo_latitude - geo_longitude I need to perform an EXTREMELY fast (low latency) retrieval of all homes within a geo-coordinate box. Something like the SQL below (if I were to use a database): SELECT * from houses WHERE latitude IS BETWEEN xxx AND yyy AND longitude IS BETWEEN www AND zzz Question: What would be the quickest way for me to store this information so that I can perform the fastest retrieval of data based on latitude & longitude? (e.g. database, NoSQL, memcache, etc)?

  • C# Dataset usage necessary before passing to GridView datasource?

    - by Goober
    Scenario Lets say for example I have a series of events that fire continually every half second presenting me with an object containing some bits of information. There are always between 10 and 15 objects that are being updated constantly. Since these bits of information are changing continually I want to display them in a GridView. When I do so, I want the user to see the data displayed in the gridview and actually be updated as opposed to just a continually extending list being printed and incrementing (like writeline on the console). Question Is the best way to achieve this to map my objects to a dataset and have the dataset mapped to the gridview? Thoughts Will this allow the gridview to just be "UPDATED" as opposed to being added to? Any implementation suggestions would be greatly appreciated. EDIT: it MUST be windows forms (I use DevExpress too)

  • @OrderBy: Sorting references

    - by Sven Moschel
    We have the following entity structure: @Entity public class SecurityRole { private List<Account> accounts; // ManyToMany } @Entity public class Account { private Employee owner; // OneToOne } @Entity public class Employee { private String lastName; } A security role can have many accounts. A account always has an employee. On the GUI we show the security roles in an mastertable. In the detail table we show the accounts of the role. To display the employee information we show "account.getOwner().getLastName()"; How can we use the @OrderBy annotation with this model? Is this possible? The problem is that the Account entity has no employee information that we can sort.

  • How do I make "simple" throughput j2ee-filter?

    - by Tommy
    I'm looking to create a filter that can give me two things: number of request pr minute, and average responsetime pr minute. I already got the individual readings, I'm just not sure how to add them up. My filter captures every request, and it records the time each request takes: public void doFilter(ServletRequest request, ...() { long start = System.currentTimeMillis(); chain.doFilter(request, response); long stop = System.currentTimeMillis(); String time = Util.getTimeDifferenceInSec(start, stop); } This information will be used to create some pretty Google Chart charts. I don't want to store the data in any database. Just a way to get current numbers out when requested As this is a high volume application; low overhead is essential. I'm assuming my applicationserver doesn't provide this information.

  • Can somebody explain the difference between exceptions and errors (specific to PHP)?

    - by letseatfood
    I am having trouble figuring the best way to display errors to my clients. Should I use exceptions or errors? For example, if the user's login information does not match the database, should I throw new Exception('Login information is incorrect. Please try again.') and catch it with an exception handler using set_exception_handler()? Or, should I use trigger_error() to display an error message to the user? I think the main issue is that I cannot differentiate between errors and exceptions. I have read a lot of "answers" to this question on the internet and in some books, but it seems that people are really divided or aren't sure. Thanks!
