Developing Windows (Vista/7) Gadgets

- by John

Apart from seeming a few, I don't know much about how gadgets work. Are they special applications, or regular apps with special styled windows? I can't think of any app I use which has asked me if I want to install a gadget... I'd have thought any application which is typically left running all the time would be suitable... Skype/MSN for example. Am I misunderstanding the point of gadgets, or are they not popular?

Dynamic LINQ OrderBy

- by John Sheehan

I found an example in the VS2008 Examples for Dynamic LINQ that allows you to use a sql-like string (e.g. OrderBy("Name, Age DESC")) for ordering. Unfortunately, the method included only works on IQueryable<T>. Is there any way to get this functionality on IEnumerable<T>?

bash - how to filter java exception info

- by Michael Mao

Hi all: We've got a multi-agent Java environment where different agent would most likely produce all sorts of exceptions thrown to stderr. Here is a sample taken from the huge exception log **java.security.AccessControlException: access denied (java.io.FilePermission ..\tournament\Driver\HotelRoomAnalyser.class read)** at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkRead(Unknown Source) at java.io.File.length(Unknown Source) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClass(EmarketSandbox.java:199) at java.lang.ClassLoader.loadClass(Unknown Source) **java.security.AccessControlException: access denied (java.io.FilePermission ..\tournament\Driver\HotelRoomAnalyser.class read)** at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkRead(Unknown Source) at java.io.File.length(Unknown Source) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClass(EmarketSandbox.java:199) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at MySmarterAgent.hotelRoomBookings(MySmarterAgent.java:108) fortunately all top-tier exceptions are denoted by no leading spaces, as wrapped by ** above. My concern is to get all of the top-tier exception name (delimited by colon :), together with the first line below which contains something like at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) Basically, something with padded style, starts with "at" and ends with ".java:108" So this info can be forwarded to the owner of that error-prone agent and let him/her fix it. My code in ~/.bashrc is incompleted now : alias startmatch='java -jar "emarket.jar" ../tournament 100'; function geterrors() { startmatch 2>"$1"; a=0; while read line do if true; then a=$(($a+1)); echo $a; fi; done } What it does now is to redirect all stderr to a text file specified by the first argument passed in, and after that, parse that text file line by line, if certain conditions returns true, echo only that line. And I am stuck with what to do inside the loop. Any suggestion is much appreciates, any hint is welcomed.

GridView not DataBinding Automatically after ObjectDataSource Select Method

- by John Polvora

I've created a objectadasource that returns a datatable, the gridview is binded to this datasource. the ODS have parameters assigned on the Page_Load event, and the ODS returns the data ok and the gridview shows it fine. the problem is i have a textbox with a filter. first I created a filterexpression in gridview, using the contents of the textbox, worked fine for me. but now I've enabled the paging in gridview. then the filterexpression is not useful now, since the ODS returns only the rows of the pagesize of gridview. I did a new ODS method that select data from parameters page and pagesize according to GridView, and it's OK. now my filter textbox passes his text property to a parameter of the ods select method, then the ods gets the data based on my filter and shows it in the grid. on the Page_Load: ObjectDataSource_Lista.SelectParameters["search"].DefaultValue = filter; ObjectDataSource_Lista.SelectParameters["id"].DefaultValue = ID.ToString(); but when I change the value of the filter, the grid doesn't refresh. on debugging. I see that the ODS Select Method is refreshed ok, but the GridView don't. So I need to call mannually the Databind() method of the grid, to refresh data. the problem is, I have a commandbutton on the grid, and if I manually databind(), the command button stops functioning, generating Page ValidateRequest errors. My question is: how to databind() the grid automatically after the datasource refreshed? ps: on the ODS Selected event, causes a infinite loop and the debug webserver crashes. Temporary solution: Created a Variable private bool wasdatabound; on the event GridView_Databound, set wasdatabound = true; on the Page_PreRenderComplete, if ((GridView1.Visible) && (!databounded)) GridView1.DataBind();

RegAsm for Class Library Used in VB6 Application

- by michael.lukatchik

To be short and to the point, I've built a C# class library that is both COM-Visible and Registered for COM Interop. I've compiled the library, which resulted in the generation of .dll and .tlb files. I have another machine that's running a VB6 application. So, I copied the .dll and .tlb files over to C:/Windows/system32 folder on the machine. I then registered those files using the following: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\Windows\system32\TestClass.dll /tlb:TestClass.tlb After the files were registered successfully, I added a project reference to the Test.tlb file from inside my VB6 app, then I tried to invoke a method in my new referenced class like so: Dim myObject As TestNamespace.TestClass Set myObject = New TestNamespace.TestClass MsgBox (myObject.TestMethod()) It doesn't work, and I receive a -2147024894 Automation Error. I've read that I shouldn't install the dll into a private folder like system32. I should either be registering in the GAC or I should be registering in another location using the "/codebase" option: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\TestClass.dll /tlb:TestClass.tlb /codebase Is there any reason I shouldn't be using system32? Past devs that have worked on this project have placed assembly files used by this VB6 project into system32 and there haven't seemed to be any issues. When I register my dll in the system32 location, I get the Automation Error. When I register my dll in another location (i.e. C:/), the method call into my class library from VB6 works as expected. What gives? I should mention that we will NOT be using the GAC to register any DLL's. That's just the way it is. Any help is appreciated. Mike

lexer/parser ambiguity

How does a lexer solve this ambiguity? /*/*/ How is it that it doesn't just say, oh yeah, that's the begining of a multi-line comment, followed by another multi-line comment.

Getting filtered results with subquery

- by josepv

I have a table with something like the following: ID Name Color 1 Bob Blue 2 John Yellow 1 Bob Green 3 Sara Red 3 Sara Green What I would like to do is return a filtered list of results whereby the following data is returned: ID Name Color 1 Bob Blue 2 John Yellow 3 Sara Red i.e. I would like to return 1 row per user. (I do not mind which row is returned for the particular user - I just need that the [ID] is unique.) I have something already that works but is really slow where I create a temp table adding all the ID's and then using a "OUTER APPLY" selecting the top 1 from the same table, i.e. CREATE TABLE #tb ( [ID] [int] ) INSERT INTO #tb select distinct [ID] from MyTable select T1.[ID], T2.[Name], T2.Color from #tb T1 OUTER APPLY ( SELECT TOP 1 * FROM MyTable T2 WHERE T2.[ID] = T1.[ID] ) AS V2 DROP TABLE #tb Can somebody suggest how I may improve it? Thanks

Spring Weblfow 2 - Double Submit

- by John W.

Hello All, I am investigating a possible issue with double submits and I am looking at the possibilty of a double submit from a webflow execution. I have read many times that webflow will handle double submits, there are plenty references here. However I then came across I a forum response on the spring source forums contradicting what I read saying, SWF synchronizes on the conversation. Only one request will be processed at a time per conversation. Take note that if you're using snapshots, then it's possible repeatedly clicking on the submit button will generate a second request. I would recommend setting history to invalidate or discard in the transition from your view-state. We do have snapshots enabled but the book notes that using snapshots actually allows to solve the double submits. Does anyone have any insight on this? Thanks.

Apache/PHP: error_log per Virtual Host?

- by Michael Stum

On one Linux Server running Apache and PHP 5, we got multiple Virtual Hosts with separate logfiles and everything. The only thing we cannot seem to separate between virtual hosts is the php error_log. Overriding this setting in the <Location> of the httpd.conf does not seem to do anything. Did I overlook something? Is there a way to have separate php error_logs for each Virtual Host?

Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

- by Michael Kohout

Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

Insert new relationship data in core data

- by michael

Hoping someone can shed some light on what I might be doing wrong here. Trying to add an "event" to a list of events, represented by a one to many (inverse) relationship: MyEvents <--- Event This is the code: MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSLog(@"MYEVENTS: %@", myEvents); NSLog(@"EVENT: %@", event); [myEvents addEventObject:event]; My context is fine, and both the myEvents and event print perfectly valid information. When I try to add the event that I have (which is passed into this view controller, having been retrieved from core data previously) with this code [myEvents addEventObject:event]; It falls over with *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance MyEvents and Event are just the default generated code. MyEvents contains only the relationship to event. Thanks.

MS SQL Server: how to optimize "like" queries?

- by duke84

I have a query that searches for clients using "like" with wildcard. For example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[LASTNAME] LIKE '%Smith%') AND ([t0].[SSN] LIKE '%123%') AND ([t0].[CLIENTNUMBER] LIKE '%123%') AND ([t0].[MDOCNUMBER] LIKE '%123%') AND ([t0].[CLIENTINDICATOR] = 'ON') It can also use less parameters in "where" clause, for example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[CLIENTINDICATOR] = 'ON') Can anybody tell what is the best way to optimize performance of such query? Maybe I need to create an index? This table can have up to 1000K records in production.

Maintain denormalized data with NHibernate EventListener

- by Michael Valenty

I have one bit of denormalized data used for performance reasons and I'm trying to maintain the data with an NHibernate event listener rather than a trigger. I'm not convinced this is the best approach, but I'm neck deep into it and I want to figure this out before moving on. I'm getting following error: System.InvalidOperationException : Collection was modified; enumeration operation may not execute. System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) System.Collections.Generic.List`1.Enumerator.MoveNextRare() System.Collections.Generic.List`1.Enumerator.MoveNext() NHibernate.Engine.ActionQueue.ExecuteActions(IList list) NHibernate.Engine.ActionQueue.ExecuteActions() NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions (IEventSource session) NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) NHibernate.Impl.SessionImpl.Flush() NHibernate.Transaction.AdoTransaction.Commit() Here's the code to make happen: using (var tx = session.BeginTransaction()) { var business = session .Get<Business>(1234) .ChangeZipCodeTo("92011"); session.Update(business); tx.Commit(); // error happens here } and the event listener: public void OnPostUpdate(PostUpdateEvent @event) { var business = @event.Entity as Business; if (business != null) { var links = @event.Session .CreateQuery("select l from BusinessCategoryLink as l where l.Business.BusinessId = :businessId") .SetParameter("businessId", business.BusinessId) .List<BusinessCategoryLink>(); foreach (var link in links) { link.Location = business.Location; @event.Session.Update(link); } } }

How can I easily maintain a cross-file JavaScript Library Development Environment

- by John

I have been developing a new JavaScript application which is rapidly growing in size. My entire JavaScript Application has been encapsulated inside a single function, in a single file, in a way like this: (function(){ var uniqueApplication = window.uniqueApplication = function(opts){ if (opts.featureOne) { this.featureOne = new featureOne(opts.featureOne); } if (opts.featureTwo) { this.featureTwo = new featureTwo(opts.featureTwo); } if (opts.featureThree) { this.featureThree = new featureThree(opts.featureThree); } }; var featureOne = function(options) { this.options = options; }; featureOne.prototype.myFeatureBehavior = function() { //Lots of Behaviors }; var featureTwo = function(options) { this.options = options; }; featureTwo.prototype.myFeatureBehavior = function() { //Lots of Behaviors }; var featureThree = function(options) { this.options = options; }; featureThree.prototype.myFeatureBehavior = function() { //Lots of Behaviors }; })(); In the same file after the anonymous function and execution I do something like this: (function(){ var instanceOfApplication = new uniqueApplication({ featureOne:"dataSource", featureTwo:"drawingCanvas", featureThree:3540 }); })(); Before uploading this software online I pass my JavaScript file, and all it's dependencies, into Google Closure Compiler, using just the default Compression, and then I have one nice JavaScript file ready to go online for production. This technique has worked marvelously for me - as it has created only one global footprint in the DOM and has given me a very flexible framework to grow each additional feature of the application. However - I am reaching the point where I'd really rather not keep this entire application inside one JavaScript file. I'd like to move from having one large uniqueApplication.js file during development to having a separate file for each feature in the application, featureOne.js - featureTwo.js - featureThree.js Once I have completed offline development testing, I would then like to use something, perhaps Google Closure Compiler, to combine all of these files together - however I want these files to all be compiled inside of that scope, as they are when I have them inside one file - and I would like for them to remain in the same scope during offline testing too. I see that Google Closure Compiler supports an argument for passing in modules but I haven't really been able to find a whole lot of information on doing something like this. Anybody have any idea how this could be accomplished - or any suggestions on a development practice for writing a single JavaScript Library across multiple files that still only leaves one footprint on the DOM?

International Assist on iPhone

- by john-gosset

Does anyone know if the International Assist feature on the iPhone works when dialing a number using the tel:// URL scheme from an application? For those unfamiliar, IA automatically prefixes the "+1" to US numbers when using the iPhone internationally. I know that this works when dialing from either the built-in Contacts or Phone apps, but can't find anything stating that it works when dialing numbers from an application. Also, is there any documentation as to whether this feature is included on Canadian (Rogers) or European iPhones (or is it only used by AT&T)? If IA does not work when dialing with a custom app, can someone point to the API that would allow me to detect that the use is roaming on a foreign network so I can essentially duplicate IA's functionality? Any help greatly appreciated!

Spring: Using "Lookup method injection" for my ThreadFactory looks not scalable.

- by Michael Bavin

Hi, We're building a ThreadFactory so everytime a singleton controller needs a new thread, i get a new instance everytime. Looking at Lookup method injection looks good but what if we have multiple threads. like: public abstract class ThreadManager { public abstract Thread createThreadDoA(); public abstract Thread createThreadDoB(); } and config: <bean id="threadManager" class="bla.ThreadManager" singleton="true"> <lookup-method name="createThreadA" bean="threadA" /> <lookup-method name="createThreadB" bean="threadB"/> </bean> <bean id="threadA" class="bla.ThreadA"> <bean id="threadB" class="bla.ThreadB"> and usage: threadManager.createThreadA(); I don't want to create an abstract "create" method for every new threadclass. Is it possible to make this generich like: threadManager.createThread(ThreadA.class); Thank you

TextRenderer.DrawText renders Arial differently on XP vs Vista

- by Michael

I have a c# application that does text rendering, something on par with a simple wysiwyg text editor. I'm using TextRenderer.DrawText to render the text to the screen and GetTextExtentPoint32 to measure text so I can position different font styles/sizes on the same line. In Vista this all works fine. In XP however, Arial renders differently, certain characters like 'o' and 'b' take up more width than in Vista. GetTextExtentPoint32 seems to be measuring the string as it would in Vista though, with the smaller widths. The end result is that every now and then a run of text will overlap the text preceding it because the preceding text gets measured as smaller than it actually is on the screen. Also, my text rendering code mimics ie's text rendering exactly (for simple formatting and english language only) and ie text rendering seems to be consistent between vista and xp - that's how I noticed the change in size of the different characters. Anyone have any ideas about what's going on? In short, TextRenderer.DrawText and GetTextExtentPoint32 don't match up in xp for Arial. DrawText seems to draw certain characters larger and/or smaller than it does in Vista but GetTextExtentPoint32 seems to be measuring the text as it would in Vista (which seems to match the text rendering in ie on both xp and vista). Hope that makes sense. Note: unfortunately TextRenderer.MeasureString isn't fast or accurate enough to meet my requirements. I tried using it and had to rip it out.
