  • Help Me With This MS-Access Query

    - by yae
    I have 2 tables: "products" and "pieces" PRODUCTS idProd product price PIECES id idProdMain idProdChild quant idProdMain and idProdChild are related with the table: "products". Other considerations is that 1 product can have some pieces and 1 product can be a piece. Price product equal a sum of quantity * price of all their pieces. "Products" table contains all products (p EXAMPLE: TABLE PRODUCTS (idProd - product - price) 1 - Computer - 300€ 2 - Hard Disk - 100€ 3 - Memory - 50€ 4 - Main Board - 100€ 5 - Software - 50€ 6 - CDroms 100 un. - 30€ TABLE PIECES (id - idProdMain - idProdChild - Quant.) 1 - 1 - 2 - 1 2 - 1 - 3 - 2 3 - 1 - 4 - 1 WHAT I NEED? I need update the price of the main product when the price of the product child (piece) is changed. Following the previous example, if I change the price of this product "memory" (is a piece too) to 60€, then product "Computer" will must change his price to 320€ How I can do it using queries? Already I have tried this to obtain the price of the main product, but not runs. This query not returns any value: SELECT Sum(products.price*pieces.quant) AS Expr1 FROM products LEFT JOIN pieces ON (products.idProd = pieces.idProdChild) AND (products.idProd = pieces.idProdChild) AND (products.idProd = pieces.idProdMain) WHERE (((pieces.idProdMain)=5)); MORE INFO The table "products" contains all the products to sell that it is in the shop. The table "pieces" is to take a control of the compound products. To know those who are the products children. For example of compound product: computers. This product is composed by other products (motherboard, hard disk, memory, cpu, etc.)

  • Debian virtual server hangs on reboot, need help debugging

    - by BubuIIC
    I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

  • What are the benefits of a classical structure over a prototyple one?

    - by Rixius
    I have only recently started programming significantly, and being completely self-taught, I unfortunately don't have the benefits of a detailed Computer science course. I've been reading a lot about JavaScript lately, and I'm trying to find the benefit in classes over the prototype nature of JavaScript. The question seems to be drawn down the middle of which one is better, and I want to see the classical side of it. When I look at the prototype example: var inst_a = { "X": 123, "Y": 321, add: function () { return this.X+this.Y; } }; document.write(inst_a.add()); And then the classical version function A(x,y){ this.X = x; this.Y = y; this.add = function(){ return this.X+this.Y; }; }; var inst_a = new A(123,321); document.write(inst_a.add()); I begun thinking about this because I'm looking at the new ecmascript revision 5 and a lot of people seem up in arms that they didn't add a Class system.

    - by Francisco P.
    Having trouble with a challenge. Let's say I have a theoretical, base 10, floating point calculator with the following characteristics Only 3 digits for mantissa 1 digit for exponent Sign for mantissa and exponent How would this machine compute the following? 300 + \sum_{i=1}^{100} 0.2 The correct result is 320. The machine's result is 300. But why? Can't get where the 20 goes goes missing... Thanks for your time.

  • need help from some professional how to redirect old or invalid url

    - by kath
    I recently upgraded a site and almost all URLs have changed. I have redirected all of them (or so I hope) but it may be possible that some of them have slipped by me. Is there a way to somehow catch all invalid URLs and send the user to a certain page and somehow know what URL the person came from so I could log this, and fix those? I'm thinking I could use .htaccess somehow but am not sure how. I am using PHP Thanks so much! error file is already in .htaccess but seems nothing going to change you can see the error file as below AddHandler application/x-httpd-php5s .php ErrorDocument 404 /content/404.php RewriteEngine on RewriteBase / to see the problem what i want result is i need some thing to redirect if some one types wrong url just check the link even if you delete half of the location at the endof url it still opens http://adsbuz.com/classifieds/abu-dhabi-uae/ it sholud go to the error page but its not giong i neeed some kind force to push it to error page thanks

  • SharePoint Returning a 401.1 for a Specific User/Computer

    - by Joe Gennari
    We have a SharePoint Services 3.0 site set up supporting about 300 users right now. This report is isolated and has never been duplicated. We have one AD user who cannot log into the SharePoint site with his account from his machine and is subsequently returned a 401.1 error. If any other user tries to log on with their account from his machine, it works okay. If he moves to another machine and logs on, it works okay. The only solution to this point has been to install FireFox on the machine. When he authenticates with FF, everything is okay. Remedies tried so far: Cleared cookies/cache Turned off/on Integrated Windows Authentication in IE Downgraded IE 8 to IE 6 Removed site from Intranet Sites zone Renamed the machine Disjoined/Rejoined Domain

  • Hyper-V R2: Need help with disk structure

    - by MojoDK
    Hi all, I'm going to use the free (non gui) version of Hyper-V R2. In my new server I have 8 disks in total (for Hyper-V R2 installation and virtual machine). Atm I'm going to run a single virtual machine, with following tasks: Windows Server 2008 R2 x64 File/Print SQL Server My question is ... with my 8 disks in the server, which disks should contain wich data? Should I install "Hyper-V R2" and VM's drive c on same physical disks? Should I use raid 1 or 5? With the above tasks, how would you structure the disks? Hope you know what I mean (I'm not english, so it's difficult to explain). Thanks!!! Mojo

    Possible Duplicate: Prevent mail being marked as spam I have an Ubuntu server that I want to be able to send out several thousand emails each containing a generic header and an unique pdf attachment containing an invoice.

Any tips would be appreciated. Thanks

  • Help with Backup Scheme for B.E 12.5

    - by Jemartin
    I'm in process of implementing a new backup scheme. I would say that I'm kind of new to it. So here my question. I'm currently using Backup Exec 12.5 on Windows Server 2008 w/Hyper-V, and IBM Adic Scalar 24. I currently backup our mail server, SQL DB, Board Server Linux Red Hat, Ftp, etc. To a Near-line which is local on our SAN I have the daily's go there as well as full. I would like to start weekly full to tape on a Saturday it takes about 2-3 days to complete the entire full to tape due to backing up from our Co-Lo as well. I have read up on the Father/son rotation but here's my issue with that I dont use tapes everyday only on the weekly full to tape will I be using them. So if there is 4 weeks in a month would I rotate in this order ( Month June WK1 =7tapes , June WK2=7 tapes, June WK3=7tapes June Wk4=7tapes with WK4 being the last tape for the month of June I would use that as a Month tape. For the month of July Wk1= June's WK1 tapes, July WK2= June's WK2 tapes July WK4 = Junes Wk4 tape for a month or would I use a set of new tapes for the last week in July. All tapes are being taking off site as well.

  • Get machine name for remote computer on local network

    - by durza
    Hi, I've 2 machines with names Comp1, Comp2. There is a DNS name for them, that mask them as one, let say DNSName. I get IP addresses for both machines via Dns.GetHostEntry("DNSName"). But when I try get Dns.GetHostEntry(ipAddress) entry.HostName always contains DNSName. I found some way to get name through WMI. But our policy doesn't allow WMI on remote machines. I can do parsing of nbstat -a output, but I would like to do some clean aproach to this. Is there some way?

  • Please Help Me Optimize This

    - by Zero
    I'm trying to optimize my .htaccess file to avoid performance issues. In my .htaccess file I have something that looks like this: RewriteEngine on RewriteCond %{HTTP_USER_AGENT} bigbadbot [NC,OR] RewriteCond %{HTTP_USER_AGENT} otherbot1 [NC,OR] RewriteCond %{HTTP_USER_AGENT} otherbot2 [NC] RewriteRule ^.* - [F,L] The first rewrite rule (bigbadbot) handles about 100 requests per second, whereas the other two rewrite rules below it only handle a few requests per hour. My question is, since the first rewrite rule (bigbadbot) handles about 99% of the traffic would it be better to place these rules into two separate rulesets? For example: RewriteEngine on RewriteCond %{HTTP_USER_AGENT} bigbadbot [NC] RewriteRule ^.* - [F,L] RewriteCond %{HTTP_USER_AGENT} otherbot1 [NC,OR] RewriteCond %{HTTP_USER_AGENT} otherbot2 [NC] RewriteRule ^.* - [F,L] Can someone tell me what would be better in terms of performance? Has anyone ever benchmarked this? Thanks!
