  • Any free (or cheaper) jqGrid alternatives?

    - by upthecreek
    jqGrid seems pretty good to me, but I don't like the price ($299! - for a JQuery plugin this seems waaay to high to me) Does anyone know of a similar component, for use with ASP.NET MVC, which is either free or less pricey? Thanks EDIT: If looks like I may have got the licensing terms wrong. From this page, it looked like there was no free for commercial use option. But, According to last poster this is incorrect. Can anyone else confirm it is free for commercial use?

  • Is using the keyword var bad in C# 2.0?

    - by Patrick
    I read an article about using C# 3 features in C# 2 where you can for instance type var x = 2; and even if the project is a 2.0 project, the Visual Studio 2008 compiler picks it up and generates the same code as it would if you type int x = 2. But what I don't get is, should you not do this in some cases? I always thought that the var keyword didn't arrive until C# 3.. If the compiler generates the same code and I can type C# 3 code and C# 2 code exactly the same, what is the differance really, because the CLI is the same, right? Quote from the link above Behind the scenes, the compiler generate regular .NET 2.0 code. Is there any difference between .NET 2.0 code and .NET 3 code?

  • How to implement IDisposable properly

    - by Vince
    Hi, I've seen so much C# code in my time as a developer that attempt to help the GC along by setting variables to null or calling Dispose() on classes (DataSet for example) within thier own classes Dispose() method that I've been wondering if there's any need to implement it in a managed environment. Is this code a waste of time in its design pattern? class MyClass : IDisposable { #region IDisposable Members public void Dispose() { otherVariable = null; if (dataSet != null) dataSet.Dispose(); } #endregion }

  • Am i passing values or adresses? [Java]

    - by Samuel
    Hello World, I am new to java and i was asking myself, if i have a class 'Example' and somewhere i make a: Example example1 = new Example(); and i add some stuff to it, lets say example1.setExampleBoolean(false); and now i make: Example example2 = example1; example2.setExampleBoolean(true); Did i say with Example example2 = example1 let example2 point to the same adress as example1? Because than i would have altered example1. In other words would, using something like: Boolean exampleBoolean = example1.getExampleBoolean(); exampleBoolean be true of false? Might be a stupid questions but for me it would change the way i'd handle problems in my programs :) Thanks in advance -Samuel

  • How to register a QueryExecuterFactory in jasper reports in java

    - by Bosso
    Hi, I implemented JRQueryExecuter and want to use it in a report. Using iReport I managed to register and use the executer. Now I want to use it in a java application, but I can't find any resources how to register the factory. I thought it's enough to have the implementation in the classpath, but I get the following exception: Caused by: net.sf.jasperreports.engine.JRException: No query executer factory class registered for tmql queries. at net.sf.jasperreports.engine.query.DefaultQueryExecuterFactoryBundle.getQueryExecuterFactory(DefaultQueryExecuterFactoryBundle.java:80) at net.sf.jasperreports.engine.util.JRQueryExecuterUtils.getQueryExecuterFactory(JRQueryExecuterUtils.java:57) at net.sf.jasperreports.engine.design.JRDesignDataset.queryLanguageChanged(JRDesignDataset.java:1006) Can anybody give me a hint? regards Hannes

  • how to render custom columns with a GenericTreeModel

    - by Giorgio Gelardi
    I have to display some data in a treeview. The "real" data model is huge and I cannot copy all the stuff in a TreeStore, so I guess I should use a GenericTreeModel to act like a virtual treeview. Btw the first column is the classic icon+text style and I think I should declare a column with a CellRendererPixbuf (faq sample), but I'm not sure what the model methods on_get_n_columns() and on_get_value() should return. It's both a Pixbuf and a string value for the same column. Any help will be appreciated.

  • convert string to date and write back into NSMutableArray

    - by padatronic
    I have a NSMutableArray I get by loading a plist into it. The date field comes in as a string and i want to change it into a nsdate. I can change an nsstring into an nsdate. My array is an array of objects like the one below; { Date = "1/1/2009" Description = "Have you ever looked at a badger and thought i wonder how far you could fire that out of a cannon? Well this talk is for you"; File = "http://www.badgerCannon.org.uk/mp3/070310pm.mp3"; Series = "The Badger planet"; Speaker = "Will Ferell"; Title = "Is it a bird, is it a plane? no its a badger"; } I loop through and pull out the date and convert it from a NSString to a NSDate. I try writing it back in using the code; [[self.MediaDataArray objectAtIndex:i] replaceObjectAtIndex:0 withObject:Date]; but it errors and i am pretty sure it is because i am not putting it back into the array in the same format, ie just as a date not as date = "date". But lets face it i don't really know! Am i barking up the wrong tree? Please help, i have got the coding equivalent of writters block, or alternatively am just being really stupid! thanks in advance

  • Difference in select for update of ... in Oracle Database 10g and 11g

    - by sax
    Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience): DECLARE v_ename bonus.ename%TYPE; BEGIN SELECT b.ename INTO v_ename FROM bonus b JOIN emp e ON b.ename = e.ename JOIN dept d ON d.deptno = e.deptno WHERE b.ename = 'Scott' FOR UPDATE OF b.ename; END; / While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

  • Hot to make COM ActiveX object work in IE 64 bit?

    - by Kurtevich
    Hi! I have a COM object embeded in ASP.NET page using <object classid="clsid:XXX...">. It works in IE 32 bit, but does not work in IE 64 bit - can't access its functions. There are no error messages, no event logs where I can get some information. The dll is in C#, includes COM visible class, compiled for Any CPU (though I also tried x86), and registered during client installation by executing regasm. This creates registry keys, well everything works fine except for IE 64. I searched internet about the issue or at least some guidlines and didn't find anything. I received an answer on another forum, something about _MERGE_PROXYSTUB (I guess it's preprocessor definition?) and ProxyStubClsid32 registry key, but not very detailed. Well, I searched again, didn't find much, and experimented: rebuilt with _MERGE_PROXYSTUB defined, created ProxyStubClsid32 keys everywhere, but with no result. What can be at least possible solutions or points to look at? Maybe there is a way at least to get the logs about why IE 64 can't access it?

  • Tomcat upgradation

    - by cedar715
    We are planning to upgrade our Tomcat from 4.1.31. Our's is an Axis 1.4 application where we have our web services. Request you to suggest the latest stable version of Tomcat 5 or Tomcat 6 suitable for our application. And the things to consider while upgrading. Will the existing 1.4 Java code base works smoothly on Tomcat 5 or 6? And going further we may write the code in JDK 1.5 as well. So, having Java 1.4 code and Java 1.5 code together, will create any problems? Kindly suggest. Please share your upgradation experiences. Thank You :)

  • 4 - 7 second delay accessing Mysql across the network

    - by Kristiaan
    Hello, our company has recently purchased a new server with the intention of replacing our aging database server. its a full 64bit 2008 enterprise system, i have got the basic server setup and configured and then installed the 64bit version of mysql on the server, this has then been configured to match where possible our existing server as much as it can. however i have noticed that when it was swapped with the production database server our software systems had an increased delay accessing the mysql database this was anything beween 4 - 7 seconds. i have tried disabling TOE, IPv6 and a few other suggested soultions to this but so far cannot find out where this slowdown is coming from. replacing the server with the production one and the delay goes away. in terms of software and hardware the servers are not very identical at all due to one being windows 2003 std with a 32bit server and the new one being windows 2008 enterprise with a 64bit server. thanks Kris

  • Which internet scenario would be better?

    - by JL
    I currently have an 8mbps (down) / 512kbps (up) telephone ADSL solution. I must say the reliability is excellent, and up until now its been the fastest connection I could get because I don't live in a cable zone. The real speed of my connection is around 7mbps, but sometimes I manage to get the full 8mbps. I use my connection for work, so it needs to be at least 99% reliable. Recently I was told by a guy who lives up the road that he has a wireless connection with an external antenna and his speeds are 20mbps / 512kbps - he's also paying about 1/2 of what I pay for my wired telephone connection. My question is, is wireless internet good enough for a power user who uses his connection for work 8 hours a day, including VPNing into servers remotely. Besides this I also enjoy playing the odd network game, not a WoW freak, but sometimes I do pick up the odd MMORPG and at times do indulge in some semi heavy gaming sprees. Will this wireless latency drive me crazy and seem slow in comparison? Will it be reliable enough, I also live in an area that snows heavily in winter. I guess its a question of - should I go wireless or not. I've only had 1 wireless connection before and that was years ago using iBurst technology and I remember it was terrible for VPN, but I guess the technology might have been improved since then? What do you guys think?

  • TRADACOMS Support in B2B

    - by Dheeraj Kumar
    TRADACOMS is an initial standard for EDI. Predominantly used in the retail sector of United Kingdom. This is similar to EDIFACT messaging system, involving ecs file for translation and validation of messages. The slight difference between EDIFACT and TRADACOMS is, 1. TRADACOMS is a simpler version than EDIFACT 2. There is no Functional Acknowledgment in TRADACOMS 3. Since it is just a business message to be sent to the trading partner, the various reference numbers at STX, BAT, MHD level need not be persisted in B2B as there is no Business logic gets derived out of this. Considering this, in AS11 B2B, this can be handled out of the box using Positional Flat file document plugin. Since STX, BAT segments which define the envelope details , and part of transaction, has to be sent from the back end application itself as there is no Document protocol parameters defined in B2B. These would include some of the identifiers like SenderCode, SenderName, RecipientCode, RecipientName, reference numbers. Additionally the batching in this case be achieved by sending all the messages of a batch in a single xml from backend application, containing total number of messages in Batch as part of EOB (Batch trailer )segment. In the case of inbound scenario, we can identify the document based on start position and end position of the incoming document. However, there is a plan to identify the incoming document based on Tradacom standard instead of start/end position. Please email to [email protected] if you need a working sample.

  • python eval weirdness

    - by amadain
    Hi Folks I have the following code in one of my classes along with checks when the code does not eval: filterParam="self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" if eval(filterParam): print "Evalled" else: print "Not Evalled\nfilterParam\n'%s'\ntmpBPSS\n'%s'\nself.recipientMSISDN\n'%s'\nself.recipientIMSI\n'%s'" % (filterParam, tmpBPSS, self.recipientMSISDN, self.recipientIMSI) I am not getting anything to 'eval'. Here are the results: Not Evalled filterParam 'self.recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and self.recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]' tmpBPSS 'bprm_DAILY_MO_919844000039#892000000' self.recipientMSISDN '919844000039' self.recipientIMSI '892000000' So I used the outputs from the above to check the code in a python shell and as you can see the code evalled correctly: >>> filterParam="recipientMSISDN==tmpBPSS.split('_')[3].split('#')[0] and recipientIMSI==tmpBPSS.split('_')[3].split('#')[1]" >>> tmpBPSS='bprm_DAILY_MO_919844000039#892000000' >>> recipientMSISDN='919844000039' >>> recipientIMSI='892000000' >>> if eval(filterParam): ... print "Evalled" ... else: ... print "Not Evalled" ... Evalled Am I off my rocker or what am I missing? A

  • Where are the really high quality and complex Swing components?

    - by jouhni
    Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?
