• Tool that auto-generate a code for accesing a xml-file

  - by alex

  My application have a configuration xml-file. That file contains more than 50 program settings. At the present time I read and save each program setting separately. I guess It is not effi?iently for such tasks. I need something that can auto-generate a code for load and save my program settings using predefined xml-schema. I found a dataset in Add New Item dialog. Unfortunately, i cannot add new code to dataset1 such as events in set-accessors of properties because of this // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. Maybe, there is a tool that allows a user to generate a wrapper for accesing a xml-file ? Such as DataSet1, but with availability to add events.

• How to synchronize two DataBase Schemas Oracle 10G?

  - by gnash-85

  Hi Masters, Good Day, I am new and very naive to Oracle DB. I am using Oracle 10G. Let me explain to you. I have one source database named ( DB1) and Target Database named (DB2). I have 2 schema's named dbs1 and dbs2 in the source database (DB1). I have exported both the database schemas in Source Database (DB1) and imported it successfully into the Target Database (DB2). Now I face a challenge in synchronizing these database schemas every time from Source DB (DB1) to Target DB (DB2). Can anyone please help in letting me know how can achieve this synchronization? It would a great help. Thanks Nash

• how to write T-SQL to compare and copy data?

  - by George2

  Hello everyone, I have two SQL Server 2008 Enterprise databases (on two machines), and one of the databases is master database and another database is slave database. I want to transfer update from a table in source database to a table in destination database (two tables are of the same schema, both of them are using a single column as unique primary key). The transfer rule is (in short, the rule is keeping the destination database the same as source database because of the update of the source database), if there is a new row in source database but not in destination database, insert the row in destination database; if a row not exists in source database but exists in destination database, delete the row in destination database; if a row's content (i.e. columns other than primary key columns) changes in source database, update the new content into destination database. thanks in advance, George

• Single SQL Server Result Set from Query

  - by JamesC

  Hi Please advise on how to merge two results in to one using SQL Server 2005. I have the situation where an Account can have up to two Settlement Instructions and this have been modeled like so: The slim-ed down schema: Account --------------------- Id AccountName PrimarySettlementId (nullable) AlternateSettlementId (nullable) SettlementInstruction ---------------------- Id Name The output I want is a single result set with a select statement something along the lines of this which will allow me to construct some java objects in my Spring row mapper: select Account.Id as accountId, Account.AccountName as accountName, s1.Id as primarySettlementId, s1.Name as primarySettlementName, s2.Id as alternateSettlementId, s2.Name as alternateSettlementName I've tried various things but cannot find a way to get the result set merged in to one where the primary and alternate FK's are not null. Finally I have searched the forum, but nothing quite seems to fit with what I need.

• How to suspend and resume browser tab groups?

  - by Robin Green

  Modern browsers such as Firefox and Chrome are able to shutdown and restore the same group of tabs they had before the next time you open them, and even sometimes remember additional tab state such as scroll position within the tab. I would like ideally to be able to select a group of tabs (about some coherent theme, perhaps) and save them away into some kind of "folder" that I could later open independently, without opening any other tabs. Obviously I can use bookmarks for this, but bookmarks are kind of old-fashioned. It would be excellent if it could also record forms that I had filled in but not submitted, scroll position, tab position within the tab group, and any other "dynamic" aspects of the current tab state.

• Symfony 1.3: different form filters generated

  - by user248959

  Hi, i have this class in rs1/lib/filter/doctrine/FelizFormFilter.class.php <?php /** * Feliz filter form. * * @package rs * @subpackage filter * @author Your name here * @version SVN: $Id: sfDoctrineFormFilterTemplate.php 23810 2009-11-12 11:07:44Z Kris.Wallsmith $ */ class FelizFormFilter extends BaseFelizFormFilter { public function configure() { } } and this in rs2/lib/filter/doctrine/FelizFormFilter.class.php <?php /** * Feliz filter form. * * @package filters * @subpackage Feliz * * @version SVN: $Id: sfDoctrineFormFilterTemplate.php 11675 2008-09-19 15:21:38Z fabien $ */ class FelizFormFilter extends BaseFelizFormFilter { public function configure() { } } Both were generated using "php symfony doctrine:build --all --and-load" and the version of symfony is 1.3.4 in both. This is the schema of both cases: Feliz: columns: name: string(20) Could you tell me why are different? One more thing in Eclipse: when i go with the mouse pointer to the word "BaseFelizFormFilter", in the second case (rs2) the yellow window with the information about the class is showed, but in the first case that yellow popup is not showed. Why? Javi

• I have a 21TB array but only 16TB is visible from Windows

  - by Relentim

  CONTROLLER Raid Controller: 3Ware 9650SE-24M8 Disks: 21 x 1TB RAID5 Stripe 64KB WINDOWS OS: Windows Server 2003 SP2 32x Disk: Dynamic 19557.44GB Volume: Capacity 15832.19GB I guess my array must have a 4KB block size which is limiting it to 16TB. I think I would have to switch to a 64KB block size to be able to see a maximum of 256TB. Or create another unit on my controller to go above 16TB of storage. Unfortunately I have already added over 16TB, ideally I would like to shrink the array and reclaim the 5 disks that aren't doing anything. I don't think this is possible. More likely, can I change the block size so 20TB becomes visible in windows?

• Merging tables in MySQL - sum up columns

  - by Alan Williamson

  I have an interesting problem, that i am sure has a simple answer, but i can't seem to find it in the docs. I have two separate database tables, on different servers. They are both identical table schema with the same primary keys. I want to merge the tables together on one server. But, if the row on Server1.Table1 exists in Server2.Table2 then sum up the totals in the columns i specify. Table1{ column_pk, counter }; "test1", 3 "test2", 4 Table2{ column_pk, counter }; "test1", 5 "test2", 6 So after i merge i want: "test1",8 "test2",10 Basically i need to do a mysqldump but instead of it kicking out raw INSERT statements, i need to do a INSERT..ON DUPLICATE KEY UPDATE statements. What are my options? Appreciate any input, thank you

• Get OpenVPN clients names to resolve through dnsmasq

  - by Fake Name

  I have a PFSense box running as an OpenVPN server. There are several remote devices that connect through the VPN (as tap devices). The VPN stuff is working, I can access the remote hardware by looking up the IP assigned to each device on the PFSense router. What I'd like is to have it so I can resolve the remote hardware addresses via DNS while on the local network. Note that this is only local-network - remote-device (they're backup boxes). I don't need to have the remote devices resolve using the local DNS forwarding agent. I have the rest of the devices on the network that need to be accessible via DNS report their name during the DHCP process. However, the IP assignment for OpenVPN tap clients, while it is dynamic (which is why I need DNS), does not seem to use the local DHCP server. How can I have my openvpn server add information for it's clients to the dnsmask resolver? Is this setup even reasonable (I'm not familiar with openVPN at all)?

• wrong data type in mysql for grails byte[] property

  - by srkiNZ84

  Hi, I have an application which is trying to save a photo to the database. I've created a grails domain class with a byte[] property and this was working well when using HSQLDB (the default in grails). However, when I changed the database to MySQL I ended up getting the following error: Data truncation: Data too long for column 'photo' at row 1 I then had a look at the schema and found that the byte[] was being created as a TINYBLOB field, which was causing the error. How can I specify that this property should correspond to a BLOB/LONGBLOB type in the database?

• Use different Solr Similarity algo for every search

  - by snickernet

  Hi Guys, Is possible in Solr 1.4 to specify which similarity class to use for every search within a single index? Let's say, I got 2 type of search (keyword and brand). For keyword search, I want to use the DefaultSimilarity class. But, for brand search, I want to use my CustomSimilarity class. I've been modifying the schema.xml to specify a single similarity class to use. But, I came to this requirement that I have to use 2 different similarity classes. I'll be glad to here your thoughts on this. Thanks in advance.

• Clone a lua state

  - by hbxfnzwpf

  Recently, I have encountered many difficulties when I was developing using C++ and Lua. My situation is: for some reason, there can be thousands of Lua-states in my C++ program. But these states should be same just after initialization. Of course, I can do luaL_loadlibs() and lua_loadfile() for each state, but that is pretty heavy(in fact, it takes a rather long time for me even just initial one state). So, I am wondering the following schema: What about keeping a separate Lua-state(the only state that has to be initialized) which is then cloned for other Lua-states, is that possible?

• How to set up Nginx as a caching reverse proxy?

  - by Continuation

  I heard recently that Nginx has added caching to its reverse proxy feature. I looked around but couldn't find much info about it. I want to set up Nginx as a caching reverse proxy in front of Apache/Django: to have Nginx proxy requests for some (but not all) dynamic pages to Apache, then cache the generated pages and serve subsequent requests for those pages from cache. Ideally I'd want to invalidate cache in 2 ways: Set an expiration date on the cached item To explicitly invalidate the cached item. E.g. if my Django backend has updated certain data, I'd want to tell Nginx to invalidate the cache of the affected pages Is it possible to set Nginx to do that? How?

• Solr match all aka *:* does not work

  - by Karussell

  Don't know what I did wrong. I have two indices with identical documents in it. The local index was replicated from a master which responds correctly, so the same solrconfig.xml and schema.xml file. But if I query the index on my local machine with *:* I get 0 docs. (other queries on my local machine are working correct) I tried jetty and tomcat for the local index. no success. The *:* behaviour is crucial for me, because some test cases are failing now. Do you have an idea what could be wrong?

• MS Excel 03 - Deleting rows that have live string identifiers in column A, while concatenating other

  - by Justin

  I have this xml document that is provided as a data feed (right off the bat I can not modify the source of the data feed) and i import it into excel with the xml import. there is no schema that comes with this xml so i get a table that ends up having a whole bunch of duplicates for an identifier, because of the unique values spread throughout the spreadsheet. XML in XLS Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01 6B 0011 Item xxj9 7B 0011 Item xxj9 0011 Item 02 0011 Item 01 xxj9 6B 0012 etc I need to delete all rows where columnA string/number matches while concatenating all potential values from Col3, Col4 & Col5 together so it looks like this Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01, 02 xxj9 6B, 7B what visual basic method would allow me to accomplish this? thanks

• Regex for xml parsing

  - by ogmios

  What is your opinon about following regexes - is it correct? To find element with spcific and required attribute "<(" + elem_name + ")(\s+(?:[^<]?\s+)" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3[^<])(.*?)" To find element with spcific but optional attribute "<(" + elem_name + ")(\s*|\s+(?:[^<]?\s+)(?:" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3)?[^<])(.*?)" Pleas not another answer "use existing xml parser". Question is - are the regexes proper or not? This is specific situation - C language in embedded system and xml is not well-formed (cannot be fixed - does not depend on me). Xml have specified schema and no problem with namespaces etc. exists.

• Is it possible to create a Mirror or Stripe volume for the boot partition in Windows 2008/R2?

  - by Georgios

  Hello, I have a server with two identical disks and I have installed Windows Server 2008 R2 on C, which is a 60GB volume on Disk 0. Using the disk manager, I have attempted to create both a Mirror and Stripe volume in Disk 1 but every time I get the same error "No extents found in the plex". This error occurs after Windows has converted both disks to Dynamic. The fact that the manager allows me to attempt to do this would point to the fact that this is possible. However I have been unable to find any solutions to this error. Any ideas on how to solve this? Thanks Georgios

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• How to call virtual function of an object in C++

  - by SoonDead

  I'm struggling with calling a virtual function in C++. I'm not experienced in C++, I mainly use C# and Java so I might have some delusions, but bear with me. I have to write a program where I have to avoid dynamic memory allocation if possible. I have made a class called List: template <class T> class List { public: T items[maxListLength]; int length; List() { length = 0; } T get(int i) const { if (i >= 0 && i < length) { return items[i]; } else { throw "Out of range!"; } }; // set the value of an already existing element void set(int i, T p) { if (i >= 0 && i < length) { items[i] = p; } else { throw "Out of range!"; } } // returns the index of the element int add(T p) { if (length >= maxListLength) { throw "Too many points!"; } items[length] = p; return length++; } // removes and returns the last element; T pop() { if (length > 0) { return items[--length]; } else { throw "There is no element to remove!"; } } }; It just makes an array of the given type, and manages the length of it. There is no need for dynamic memory allocation, I can just write: List<Object> objects; MyObject obj; objects.add(obj); MyObject inherits form Object. Object has a virtual function which is supposed to be overridden in MyObject: struct Object { virtual float method(const Input& input) { return 0.0f; } }; struct MyObject: public Object { virtual float method(const Input& input) { return 1.0f; } }; I get the elements as: objects.get(0).method(asdf); The problem is that even though the first element is a MyObject, the Object's method function is called. I'm guessing there is something wrong with storing the object in an array of Objects without dynamically allocating memory for the MyObject, but I'm not sure. Is there a way to call MyObject's method function? How? It's supposed to be a heterogeneous collection btw, so that's why the inheritance is there in the first place. If there is no way to call the MyObject's method function, then how should I make my list in the first place?

• move data from one table to another, postgresql edition

  - by IggShaman

  Hi All, I'd like to move some data from one table to another (with a possibly different schema). Straightforward solution that comes into mind is - start a transaction with serializable isolation level; INSERT INTO dest_table SELECT data FROM orig_table,other-tables WHERE <condition>; DELETE FROM orig_table USING other-tables WHERE <condition>; COMMIT; Now what if the amount of data is rather big, and the <condition> is expensive to compute? In PostgreSQL, a RULE or a stored procedure can be used to delete data on the fly, evaluating condition only once. Which solution is better? Are there other options?

• How can this be done with (N)Hibernate?

  - by Vilx-

  I'm creating a windows forms application with NHibernate. It's an MDI application, so there is no limit to how many forms the user can have open at the same time (probably many). For most forms I want to have an "OK" and a "Cancel" button. Both close the form, but "OK" also saves the modified data to the DB. The forms can be pretty complex, and the modifications are likely to touch a whole graph of objects, adding some, deleting some, and changing some more. It would be good if the changes could be automatically detected and persisted as needed, without the need to manually keep track of each of them. What would be a good way to do this? Extra information: I can make whatever DB schema I want. I'm using MSSQL 2008 and currently have decided for GUID primary keys (with guid.comb generator) and a TIMESTAMP column for optimistic concurrency. I tried to simply set FlushMode of a NHibernate ISession to Never, doing all modifications as needed, and then calling Flush() if the user clicked OK. But that didn't work.

• Crystal Reports XSD file required?

  Hi, I am trying to create a new report using the PUSH MODEL to supply data. I am creating a DataTable in my C# code and pushing this to a report using a template. I have created a report template and an XSD (using DataSet.WriteXmlSchema) and added this to my report using the Database Expert option. I have since deleted the xsd schema but the report still seems to be working. I was wondering why this was happening. Is the xsd file stored in the report? Thanks a lot. Ravi

• Looking for alternatives to the database project.

  - by Dave

  I've a fairly large database project which contains nine databases and one database with a fairly large schema. This project takes a large amount of time to build and I'm about to pull my hair out. We'd like to keep our database source controlled, but having a hard getting the other devs to use the project and build the database project before checking in just because it takes so long to build. It is seriously crippling our work so I'm look for alternatives. Maybe something can be done with Redgate's SQL Compare? I think maybe the only drawback here is that it doesn't validate syntax? Anyone's thoughts/suggestions would be most appreciated.
