  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • Embedded scripting engine in .Net app

    - by Nate
    I am looking to replace an old control being used for scripting an application. The control used to be called SAX Basic, but is now called WinWrap. It provides us with two primary functions. 1) It's a scripting engine (VB) 2) It has a GUI for developing and debugging scripts that get run in the hosting application. The first feature it provides is actually pretty easy to replace. There are so many great methods of running just about any kind of code at runtime that it's almost a non-issue. Just about any language targeting the .Net runtime will work for us. We've looked at running C#, PowerShell, VB.Net, IronPython, etc. I've also taken a brief look at Lua and F#, but honestly the language isn't the biggest barrier here. Now, for the hard part that seems to keep getting me stuck. We want a code editor, and debugger. Something simple, not unlike PowerShell's ISE would be fine. Just as long as a file could be created, saved, debugged and executed. I'm currently looking into Visual Studio 2010 Shell (Isolated) and I'm also looking at the feasibility of embedding PowerShell ISE in my application. Are there any other editor's I could embed/use in my application? Purchasing a product is not out of the question. It comes down to a combination of ease of use, how well it meets our needs, and how simple deployment and licensing is for developers. Thanks for the pointers

  • Unexpected variable update when using bash's $(( )) operator for arithmetic

    - by philo
    I'm trying to trim a few lines from a file. I know exactly how many lines to remove (say, 2 from the top), but not how many total lines are in the file. So I tried this straightforward solution: $ wc -l $FILENAME 119559 my_filename.txt $ LINES=$(wc -l $FILENAME | awk '{print $1}') $ tail -n $(($LINES - 2)) $FILENAME > $OUTPUT_FILE The output is fine, but what happened to LINES?? $ wc -l $OUTPUT_FILE 119557 my_output_file.txt $ echo $LINES 107 Hoping someone can help me understand what's going on.

  • Statically checking a Java app for link errors

    - by monorailkitty
    I have a scenario where I have code written against version 1 of a library but I want to ship version 2 of the library instead. The code has shipped and is therefore not changeable. I'm concerned that it might try to access classes or members of the library that existed in v1 but have been removed in v2. I figured it would be possible to write a tool to do a simple check to see if the code will link against the newer version of the library. I appreciate that the code may still be very broken even if the code links. I am thinking about this from the other side - if the code won't link then I can be sure there is a problem. As far as I can see, I need to run through the bytecode checking for references, method calls and field accesses to library classes then use reflection to check whether the class/member exists. I have three-fold question: (1) Does such a tool exist already? (2) I have a niggling feeling it is much more complicated that I imagine and that I have missed something major - is that the case? (3) Do you know of a handy library that would allow me to inspect the bytecode such that I can find the method calls, references etc.? Thanks!

  • Update thousands of records in a DataSet to SQL Server

    - by MSIL
    I have half a million records in a data set of which 50,000 are updated. Now I need to commit the updated records back to the SQL Server 2005 Database. What is the best and efficient way to do this considering the fact that such updates could be frequent (though concurrency is not an issue but performance is)

  • JPA atomic query/save for multithreaded app

    - by TofuBeer
    I am in the midst of changing my JPA code around to make use of threads. I have a separate entity manager and transaction for each thread. What I used to have (for the single threaded environment) was code like: // get object from the entity manager X x = getObjectX(jpaQuery); if(x == null) { x = new X(); x.setVariable(foo); entityManager.persist(x); } With that code in the multi threaded environment I am getting duplicate keys since, I assume, getObjectX returns null for a thread, then that thread is swapped out, the next thread calls getObjextX, also getting null, and then both threads will create and persist a new X(). Short of adding in synchronization, is there an atomic way to get/save-if-doesn't-exist a value with JPA or should I rethink my approach EDIT: I am using the latest Eclipselink and MySql 5.1

  • Is app stability unusually hard with Java?

    - by wrp
    Java's extensive libraries and tool support are appealing, but I've never tried developing with it because most Java applications I've used have been extremely buggy. This has me puzzled, because I hear that Java is the dominant platform for enterprise development. Maybe it's fine for server-side stuff but not desktop applications. I'm not talking about things like the long compile/startup times or the random latencies due to garbage collection. This is about things just going wrong. Some of the most common problems I see are: corrupted icons corrupted fonts, in menus usually and editing areas sometimes inaccurate framing of GUI elements dialogs sometimes popping up blank Maybe the problems are mostly with Swing. I've rarely used a Java application long enough to find deeper issues. I can think of a few possible explanations for what I've experienced: It's possible to write stable apps with Java, just harder. Java apps are always buggy and enterprise users just put up with it. Server-side apps are fine because just Swing is buggy. I'm living under a curse and need the services of a good witchdoctor.

  • Redirect window of command line tool to your app (Windows)

    - by dribler
    Hello, is there a way (on Windows XP+) to redirect the output of a window created by a process created with e.g. CreateProcess to a window of your own program? I'd like to make a nicer GUI for ffplay.exe which is an open source video player. It is a command line tool, which opens a simple window in which it plays back the video. Can I "capture" this window and display the output in my own program somehow? Thanks for any hints you can provide.

  • Put specific tds from a table row into edit using jQuery (then update w/ ajax)

    - by bbqsauced
    I'm somewhat new to jQuery, so I could use some help here. This is my issue: I have a php script outputting a dynamic table. Each row has an "edit" button, plus some other fields. Only 3 of those need to be turned into an input box. The edit button should only put that specific row into "edit mode." I got as far as assigning each row a unique class by adding a number to the end of it. I have been able to use jQuery to change all of the rows into edit mode, but I need it to be specific to a row. An example row would have classes like name0, price0, and desc0. The next row would go on to classes name1, price1, and desc1 (for the fields that need changed). How can I reference these values and pass them to jQuery so it processes an event on just those elements?

  • unclear use of @property in window app using core data

    - by Matt
    Looking through a Window based application ive used to experiment with as a way of getting my head around core data, ive noticed that the appdelegate has the following code myAppDelegate.h #import <UIKit/UIKit.h> #import <CoreData/CoreData.h> @interface iCaptureFreeAppDelegate : NSObject <UIApplicationDelegate> { NSManagedObjectModel *managedObjectModel; NSManagedObjectContext *managedObjectContext; NSPersistentStoreCoordinator *persistentStoreCoordinator; UIWindow *window; UITabBarController *tabBarController; } myAppDelegate.m #import "myAppDelegate.h" @interface iCaptureFreeAppDelegate (PrivateCoreDataStack) @property (nonatomic, retain, readonly) NSManagedObjectModel *managedObjectModel; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator; @end @implementation iCaptureFreeAppDelegate @synthesize window, tabBarController; // code .... // - (NSManagedObjectContext *) managedObjectContext { } - (NSManagedObjectModel *)managedObjectModel { } - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { } // etc..... i want to understand a few things about what this project is doing why the properties in the category declaration? (if i delete the privateCoreDataStack category everything still works...) why the properties appear to be linked with the methods in the implementation ... managedObjectContext {} etc why the members in the .h file have the same name as the properties and the methods why code completion lets me use dot '.' to access the members but then fails on compilation say it cant find a getter thanks !

  • Flex 4 app, coldfusion help

    - by ihaveitnow
    I have some* experience using the flex framework for building web apps. But I have no experience with server side languages, I have heard the saying "choose one and stick to it" several times in reference to programming. I have chosen coldfusion. Now I have no clue what to do or where to start. Now to the details: It will be a site for food showcases. Food menus sorted by cultural origin, vegetarian or meat kind, etc. Things like that. I intend to build a web site that enables subscriptions, and keeps them updated whenever updates are made. And a commenting system to encourage user feedback. And I would like the site to have a database of food items (as mentioned earlier); from my research coldfusion will enable me to do this. I would like resources that I could go to, and do more research myself. And all recommendations that can be provided. Whether you think I dont need coldfusion, and if I can get this done with just flex and as3. I appreciate all feedback, thanks for taking the time to read and respond. * = not much experience, still a "beginner"

  • Problem running VBScript from my UIAccess VB app using MSScriptControl

    - by Ray
    I'm trying to run some VBSCRIPT from within my application. This works fine when I run my program from within VB. But once I add "UIAccess=true" to my manifest and digitally sign my exe with my certificate, I am unable to run the code any more. It gives errors when I try to interface with any program saying "429: ActiveX component can't create object: 'myApp.Application'". Anyone have any idea why it would run fine in the IDE but not with an application with uses UIAccess? Here is the code: Dim scriptRunner As New MSScriptControl.ScriptControlClass scriptRunner.Language = "VBScript" scriptRunner.AllowUI = True scriptRunner.Timeout = 3000 scriptRunner.AddCode(scriptStr) scriptRunner = Nothing

  • how to configure hibernate not to update @Version on each access to entity

    - by radai
    i have a simple query that returns an entity, and when i look at hibernate SQL output i see that when i execute this query hibernate updates the @Version field (on each consecutive read the @version field is updated). i dont modify anything in the entity i fetch, and i dont pass is as an argument to either persist or merge. this effectively means every read i make turns into a read+write. i've tried setting the lock mode t oboth NONE (jpa 2) and READ (jpa 1) to no avail. is there any way to achieve this? if so, is there any way to set this as the default behavior in persistence.xml in some way ? im using jpa2 over hibernate 3.6

    I need to get the offset of the element that is being dragged and I use: $(function(){ $(".draggable").draggable({ stop: function(){ var offset = $("#boxone").offset(); alert(offset.left); } }); }); the element is positioned absolute and has a CSS of: left:100px; that is the value I get on the alert when I drag the element (even multiple times). What I want is to get it to alert the current offset (if I drag in 200px to the right it should say 300)

  • MySQL update error when special characters are used

    - by Katy
    Hi All, I was wondering if anyone had come across this one before. I have a customer who uses special characters in their product description field. Updating to a MySQL database works fine if we use their HTML equivalents but it fails if the character itself is used (copied from either character map or Word I would assume). Has anyone seen this behaviour before? The character in question in this case is ø - and we can't seem to do a replace on it (in ASP at least) as the character comes though to the SQL string as a "?". Any suggestions much appreciated - thanks!

I know how to manually do it by writing an sql that performs an action to all records older than x time based on the timestamp. How would this be done automatically? Kind Regards, Nich
