  • ASP.NET - Update Dataset directly to DB

    - by karthik
    Hi, Description: I wanted to update dataset to database in Asp.NET. Instead of retrieving the entire table, I am retrieving only one record using the following statement :- select * from Products where ProductID=3 Now I wanted to update dataset directly in to DB by using following statements (DAP 4.1) db.UpdateDataSet(ds, ds.Tables[0].TableName, null, cmdupdate, null, UpdateBehavior.Standard); Questions Can I Retrieve only one row from DB while a lot of other records are there and update back using Adapter update? ( In other words, I am not selecting all records from table) I am using Data Application Block 4.1? It will work there right? If anyone can give example for update will be great ( with Procedures). Thanks Ka

  • Look over my C# SQLite Query, what am I doing wrong?

    - by CODe
    I'm writing a WinForms database application using SQLite and C#. I have a sqlite query that is failing, and I'm unsure as to where I'm going wrong, as I've tried everything I could think of. public DataTable searchSubs(String businessName, String contactName) { string SQL = null; if ((businessName != null && businessName != "") && (contactName != null && contactName != "")) { // provided business name and contact name for search SQL = "SELECT * FROM SUBCONTRACTOR WHERE BusinessName LIKE %@BusinessName% AND Contact LIKE %@ContactName%"; } else if ((businessName != null && businessName != "") && (contactName == null || contactName == "")) { // provided business name only for search SQL = "SELECT * FROM SUBCONTRACTOR WHERE BusinessName LIKE %@BusinessName%"; } else if ((businessName == null || businessName == "") && (contactName != null && contactName != "")) { // provided contact name only for search SQL = "SELECT * FROM SUBCONTRACTOR WHERE Contact LIKE %@ContactName%"; } else if ((businessName == null || businessName == "") && (contactName == null || contactName == "")) { // provided no search information SQL = "SELECT * FROM SUBCONTRACTOR"; } SQLiteCommand cmd = new SQLiteCommand(SQL); cmd.Parameters.AddWithValue("@BusinessName", businessName); cmd.Parameters.AddWithValue("@ContactName", contactName); cmd.Connection = connection; SQLiteDataAdapter da = new SQLiteDataAdapter(cmd); DataSet ds = new DataSet(); try { da.Fill(ds); DataTable dt = ds.Tables[0]; return dt; } catch (Exception e) { MessageBox.Show(e.ToString()); return null; } finally { cmd.Dispose(); connection.Close(); } } I continually get an error saying that it is failing near the %'s. That's all fine and dandy, but I guess I'm structuring it wrong, but I don't know where! I tried adding apostrophes around the "like" variables, like this: SQL = "SELECT * FROM SUBCONTRACTOR WHERE Contact LIKE '%@ContactName%'"; and quite honestly, that is all I can think of. Anyone have any ideas?

  • Setting the rank of a user-defined verb in J

    - by Gregory Higley
    Here's a function to calculate the digital sum of a number in J: digitalSum =: +/@:("."0)@": If I use b. to query the rank of this verb, I get _ 1 _, i.e., infinite. (We can ignore the dyadic case since digitalSum is not dyadic.) I would like the monadic rank of this verb to be 0, as reported by b.. The only way I know of to do this is to use a "shim", e.g., ds =: +/@:("."0)@": digitalSum =: ds"0 This works great, but I want to know whether it's the only way to do this, or if there's something else I'm missing.

  • Using Linq on a Dataset

    - by JasonMHirst
    Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

  • DataSet XML export is empty

    - by Shaine
    I've got in-memory dataset with couple of tables that is populated in code. Data-bound grids on the gui show table contents without a problem. Then I try to export the dataset into XML: ds.WriteXml(fdSave.FileName, XmlWriteMode.WriteSchema); and get empty XML (with couple of lines regarding dataset names but without any tables) If I export table directly I've got all the data but dataset name is obviously wrong: ds.Fields.WriteXml(fdSave.FileName, XmlWriteMode.WriteSchema); What am I missing? Is there any reasonable way to write the whole dataset into file?

  • Linkage of namespace functions

    - by user144182
    I have a couple of methods declared at the namespace level within a header for a class: // MyClass.h namespace network { int Method1(double d); int Method2(double d); class MyClass { //... } } then defined in //MyClass.cpp int Method1(double d) { ... } int Method2(double d) { ... } This project compiles cleanly and is a dependency for a ui project which uses MyClass. The functions were previously member functions of MyClass, but were moved to namespace since it was more appropriate. My problem is the ui project complains when it gets to the linker: 1network.lib(MyClass.obj) : error LNK2001: unresolved external symbol "int __cdecl network::Method1(double)" (?INT@ds@sim@@YAHN@Z) 1network.lib(MyClass.obj) : error LNK2001: unresolved external symbol "int __cdecl network::Method2(double)" (?CINT@ds@sim@@YAHN@Z) What am I doing wrong?

  • Is it possible to create an enum whose instance can't be created but can be used for readonly purpos

    - by Shantanu Gupta
    I created an enum where I stored some table names. I want it to be used to get the name of the table like ds.Tables[BGuestInfo.TableName.L_GUEST_TYPE.ToString()]. public class a { public enum TableName : byte { L_GUEST_TYPE = 0 ,L_AGE_GROUP = 1 ,M_COMPANY = 2 ,L_COUNTRY = 3 ,L_EYE_COLOR = 4 ,L_GENDER = 5 ,L_HAIR_COLOR = 6 ,L_STATE_PROVINCE = 7 ,L_STATUS = 8 ,L_TITLE = 9 ,M_TOWER = 10 ,L_CITY = 11 ,L_REGISTER_TYPE = 12 } } class b { a.TableName x; //trying to restrict this ds.Tables[a.TableName.L_GUEST_TYPE] //accessible and can be used like this } This is my enum. Now I have not created any instance of this enum so that no one can use it for other than read only purpose. For this enum to be accessible in outer classes as well I have to make it public which means some outer class can create its object as well. So what can i do so as to restrict its instance creation.

  • How to efficiently convert DataSet.Tables to List<DataTable>?

    - by Soenhay
    I see many posts about converting the table(s) in a DataSet to a list of DataRows or other row data but I was unable to find anything about this question. This is what I came up with using in .Net 3.0: internal static List<DataTable> DataSetToList(DataSet ds) { List<DataTable> result = new List<DataTable>(); foreach (DataTable dtbl in ds.Tables) { result.Add(dtbl); } return result; } Is there a better way, excluding an extension method? Thanks

  • LCM says Smart List import is complete but actually its not...Here are probable reasons

    - by RahulS
    First of all some basics of smart list: Administrators use Smart Lists to create custom drop-down lists that users access from data form cells. When clicking in cells whose members are associated with a Smart List (as a member property), users select items from drop-down lists instead of entering data. Users cannot type in cells that contain Smart Lists. Smart Lists display in cells as down arrows that expand when users click into the cells. Below link will give you more information on Smart Lists: http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/enum_pg.html I got a simple query today, "The LCM process generates and indicates a status of "Complete", however, the 3,018 records do not appear in the Planning application. No error exists in the log to identify the problem." Things which can be checked in this case: 1. Spaces are not allowed in the Entry Name, 2. Spaces are allowed in the Entry Label, 3. The name must start with an alpha character or underscore, 4. Valid characters for the remaining part of the name must be alpha, numeric, or an underscore, 5. Enter a name that is unique within the smart list, 6. I am not sure about the limits but I have seen 22,000 members loaded fine, 7. ID for every entry should be unique,  8. IDs need not to be consecutive, Ex: It was go from 1 to 100 then 500 to 900 then 1900 to 4500 etc. While import .xml file using LCM there were no errors in the foundation and LCM migration logs, but when checked in the HyS9PlanningSysErr.log, few errors were found:Ex: The name Data_Coord_(Prod)_ACS is invalid, The name Sr_Dir_b+Medcd_Gvt_Rel_Sls_Mkt is invalid, The name entered is invalid. Enter a name that is unique within the smart list, Also, we can Load Smart List dimensions and Smart List dimension entries using the /DS:HSP_SMARTLISTS parameter in outlineload utility: OutlineLoad /A:acpt /U:admin /M /I:c:/smartlist_create1.csv /DS:HSP_SMARTLISTS /L:c:/OutlineLogs/outlineLoad.log /X:c:/OutlineLogs/outlineLoad.exc SmartList Name, Operation, Label, Display Order, Missing Label, Use Form Missing Label, Entry ID, Entry Name, Entry Label SL1,addsmartlist,SL1Label,,,,,, SL1,addEntry,,,,,,entry1,entrylabel1 SL1,addEntry,,,,,,entry2,entrylabel2 Cheers..!!!

  • What are some good game development programs for kids?

    - by John Giotta
    I know a very bright little boy who excels in math, but at home he's glued to his Nintendo DS. When I asked him what he wanted to do when he grew up he said "Make video games!" I remember a few years there was mention of a MIT software called Scratch and thought maybe this kid can do want he wants to do. Has anyone used any of the "game development" for kids softwares out there? Can you recommend any?

  • JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

    - by mfarver
    I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

  • jboss 5.1 mysql connection pooling

    - by boyd4715
    I am using JBOSS 5.1.0.GA, MySQL 5.5 and Hibernate 3.3.1 GA (included with JBOSS) + Spring. My question is do I need to add c3p0 as a data source in my spring/hibernate configuration for connection pooling or are the setting in the JBOSS mysql-ds.xml setting enough. My mysql-ds.xml is the following: <datasources> <local-tx-datasource> <jndi-name>MySqlDS</jndi-name> <connection-url>jdbc:mysql://localhost:3306/ecotrak</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>ecotrak</user-name> <password>ecotrak</password> <min-pool-size>5</min-pool-size> <max-pool-size>20</max-pool-size> <idle-timeout-minutes>5</idle-timeout-minutes> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name> <!-- should only be used on drivers after 3.22.1 with "ping" support --> <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name> <!-- sql to call when connection is created <new-connection-sql>some arbitrary sql</new-connection-sql> --> <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql> --> <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> <metadata> <type-mapping>mySQL</type-mapping> </metadata> </local-tx-datasource> </datasources>

  • Datastage 8.7 installs fine on Window7 without any errors but it can not launch localhost:9080 web console

    - by user265273
    When I launch the web console, I get page can not be displayed error. What I have tried so far: I have re-installed DS about 7 times, and each time, I get same errors. I added entries in etc/hosts file for local host and my host name. I have turned off firewall. My hardware/software setup. My host system is window8.1. My vmware workstation is 7. The guest os is windows 7 enterprise x64. I have installed 10g, and given dba role to public. I have installed VS 5, and ms visual c++ 2010 express. I have installed msxml. IE version is 10. Firewall is off. My internet works fine It passed all the DS requirement tests and install completed successfully. When I launch my vmware guest instance, I do get SQL5000c error upon boot which I have tried to ignore in some installs and in some, I used db2systray -clean command to get rid of it. But that has not helped solve the webconsole connect failure to my host. I have spent over 2 weeks exclusively on this issue and badly need some help.

  • AVD Screen orientation not changing with CTRL+F11 or CTRL+F12

    - by Brad Hein
    I run my app in the AVD emulator using eclipse but I'm unable to change the screen orientation in the AVD (Android 2.0 platform on the emulator). When I press CONTROL+F11 or CONTROL+F12 on the keyboard, nothing happens. No messages are generated in the adb debuglog/logcat either when I press either hotkey. According to http://developer.android.com/guide/developing/tools/emulator.html these are the correct hotkeys to switch the emulator's screen orientation. I tried it with my app, and with the messaging app. The hotkey has no affect in any case. I'm running Fedora 12, Gnome. I checked my Keyboard Shortcuts in the System - Preferences menu, nothing's attached to either hotkey. Same problem, 3 different PCs (all running Fedora Gnome).

  • SVN correct directory structure

    - by jax
    I followed this tutorial to setup SVN on my Fedora box http://www.ashishkulkarni.com/installing-subversion-on-fedora-linux/ It worked. However, there is no trunk, tags or branches when I set this up. In the tutorial he creates a sandbox project /svn/repos/sandbox Now I am assuming that all projects will go under repos /svn/repos/project1 /svn/repos/project2 When I view the project there are no trunk, tags or branches, I have not yet checked in any project, will these appear when I do that? As I understand all my files should go below the trunk. What are the tags and branches for? Just some clarification about the structure would be nice. Thanks.
