• Keeping messages in queue in case of receiver crash

  - by John Doe

  Hi, We've a Spring JMS message listener container for receiving messages asynchronously. Using DefaultMessageListenerContainer and in sessionTransacted mode. I understand being in sessionTransacted mode means in case of an exception the message will be put back into the queue. But how can I make sure the message won't be deleted from the queue even if the receiver (which is picked the message) crashes or just the machine running it looses power? At first I thought CLIENT_ACKNOWLEDGE acknowledge mode should save me, but apparently it's not the case, Spring calls .acknowledge() no matter what. So here's my question, how can I guarantee the delivery? Using a custom MessageListenerContainer? Using a transaction manager?

• How to install older Android SDK in Eclipse

  - by John Brunner

  I'm working at the moment at a simple app in eclipse for android. Just receiving and sending data, and using the camera API. I've set the minSDKversion to 8, because I think that has the widest user base. But at the beginning of the project eclipse was asking me which target SDK version I would use, and because I had just one installed (the latest 4.0.3) I've took this. Now I'm asking me if it wouldn't be wiser to install a lower SDK, like Android 2.2, because it would be not that big (compared to the 4.0.3) and my app would not have included all the fancy new features, which are not used in any way?! Or is this complete nonsense I'm talking here, and just should take my 4.0.3 SDK? When not, how can I install a lower version? Help -> SDK Manager is not showing old SDKs...

• Memory leak with ContextMenuStrip

  - by Dave

  I'm creating a lot of custom controls and adding them to a FlowLayoutPanel. There is also a ContextMenuStrip created and populated at design time. Every time a control is added to the panel it has its ContextMenuStrip property assigned to this menu, so that all controls "share" the same menu. But I noticed when the controls are removed from the panel and disposed of, the memory in use in Task Manager doesn't drop. It rises around 50kB every time a control is created and added to the layout panel. I downloaded the trial of .NET Memory Profiler and it showed there were references to the menu strip hanging around after the controls were disposed. I changed the code to explicitly set the ContextMenuStrip property to null before disposing of the control, and yep, the memory is now released. Why is this? Shouldn't the GC clean up this type of thing?

• How to program three editions Light, Pro, Ultimate in one solution

  - by Henry99

  I'd like to know how best to program three different editions of my C# ASP.NET 3.5 application in VS2008 Professional (which includes a web deployment project). I have a Light, Pro and Ultimate edition (or version) of my application. At the moment I've put all in one solution with three build versions in configuration manager and I use preprocessor directives all over the code (there are around 20 such constructs in some ten thousand lines of code, so it's overseeable): #if light //light code #endif #if pro //pro code #endif //etc... I've read in stackoverflow for hours and thought to encounter how e.g. Microsoft does this with its different Windows editions, but did not find what I expected. Somewhere there is a heavy discussion about if preprocessor directives are evil. What I like with those #if-directives is: the side-by-side code of differences, so I will understand the code for the different editions after six months and the special benefit to NOT give out compiled code of other versions to the customer. OK, long explication, repeated question: What's the best way to go?

• jQuery 1.4.2 - Ajax & increasing IE 8 Process Handles

  - by mac866

  Hi, I'm requesting every second some data over $.ajax. $.ajax({ type: "POST", url: "ServiceEndpointUrl", data: "", success: function(result) { ... Do Work ... } } } } }); This code leads into an continuous growing number of handles in IE 8 (Windows 7 / verified with Task Manager & Process Explorer). Firefox & Chrome does not have this problem. This page is displayed all day long - this leads into thousands of handles & will sometimes crash the complete browser. My workaround is to reload the complete page every hour - but this can't be the solution ;-) Any suggestions how to "close" these Ajax-Handles? thx

• Cycling tabs graphically

  - by abernier

  Mac OS X's window manager is composed of: Applications Windows Tabs By default on OS X, you can cycle over applications with the famous ?? shortcut. In addition to this, I use a little utility called Witch which enables cycling (graphically) over windows too(I've defined it on ??). Unfortunately, it does not currently support tabs cycling... Would you have any suggestion for this? I know I already can ^? for this, but I'm looking for a graphical utility where you are not blind during cycling. Thank you.

• What is the weirdest language you have ever programmed in?

  - by sfoulk526

  For me, it was Forth, way back at the end of the eighties! Yes, almost prehistory. But I was an un-degree-ed programmer, unable to afford college, self-taught C and Assembly, and not enough experience to open doors. I was invited to work in software engineering, my dream job by the engineering manager of my company, but...I had to do it in Forth, and the company was willing to teach me. The position was my start into embedded systems programming, and man did I learn a lot! Like, just how easy C and Assembly language REALLY could be! But it was a good journey, and though I never coded again in Forth, my fear of not being able to learn C and Assembly proficiently disappeared... ;-)

• MS SQL Server 2000 tables

  - by klork

  We currently have an MS SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: 1) Does anyone have any experience with a MS SQL Server (2000/2005) installation with millions of tables? 2) What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. 3) What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

• What alternatives are there for asp.net forms authentication?

  - by Eytan Levit

  Hi, We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security: a simple user - that can only access basic data that is in a data repository a manager - that can open up data repositories a superuser - that can open up repository factories. each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us: 1. Scalability. 2. Customization. 3. To create permissions that will effect the GUI + deny access to certain pages. 4. To create predefined roles - that will allow for easy setup of new users. 5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles. Thanks in advance

• Trying to modify a constraint in PostgresSQL

  - by MISMajorDeveloperAnyways

  Postgres is getting quite annoying lately. I have checked the documentation provided by Oracle and found a way to do this without dropping the table. Problem is, it errors out at modify as it does not recognize the keyword. Using EMS SQL Manager for PostgreSQL. Alter table public.public_insurer_credit MODIFY CONSTRAINT public_insurer_credit_fk1 deferrable, initially deferred; I was able to work around it by dropping the constraint using : ALTER TABLE "public"."public_insurer_credit" DROP CONSTRAINT "public_insurer_credit_fk1" RESTRICT; ALTER TABLE "public"."public_insurer_credit" ADD CONSTRAINT "public_insurer_credit_fk1" FOREIGN KEY ("branch_id", "order_id", "public_insurer_id") REFERENCES "public"."order_public_insurer"("branch_id", "order_id", "public_insurer_id") ON UPDATE CASCADE ON DELETE NO ACTION DEFERRABLE INITIALLY DEFERRED;

• ajax page works in development (vs2010) but does a full postback on production win2k8R2

  - by merk

  Hi all, I have a stupid simple page. I've got a panel and a button. Clicking the button either hides or displays the panel. That much works. I added in a script manager control and update panel - put all the page contents in the updatepanel/contenttemplate When i run this under vs2010 and click the button, the page does NOT post back - the panel just appears or disappears without the whole page refreshing, which is what i wanted. I upload this to my IIS7.5 server and the page is posting back/whole page is refreshing when i click the button. Do i need to configure anything on the server to enable ajax? thanks

• Forcing a method to be non-transactional in JPA (Eclipselink)

  - by rhinds

  Hi, I am developing an application using Eclipselink and as part of the app I need to be able to manipulate some of the objects which involves changing data without it being persisted to the database (i merging/changing objects for some batch generation processes). I am reluctant to change the data in the Entity objects, as there is a risk that even though i have not marked the methods as @Transactional, this method could in the future be inadvertantly called from within a transactional method and these changes could be persisted. So my question is, is there anyway to get around this? Such as force a method to always be non-transactional regardless; terminate any transactionality as soon as the method is started; etc. I know there is a .detach() method that can detach the objects from the Entity Manager, however, there are many objects and this seems like a potentially error prone fail-safe on my code.

• Trying to programmatically add a SQL Alias to the registry (just need help with parameters)

  - by nycgags

  Normally when we spin up a new instance we need to add an alias on one of our boxes so we can easily connect to it through SSMS using SQL Server Configuration Manager. I have written a batch file which adds the appropriate entry into the registry (it is actually two batch files, one for 32 bit and one for 64 bit). I am not sure how to get this to run with parameters though. I know %1 and %2 would be for the first two parameters, but when I run this, in the registry it actually puts %1 and %2 as the value pair. if you hardcode hostname and IP Address in place of %1 and %2 the batch file works as expected: REGEDIT4 ; @ECHO OFF ; CLS ; REGEDIT.EXE /S "%~f0" ; EXIT [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo] "%1"="DBMSSOCN,%2,1433"

• MongoDB or CouchDB - fit for production?

  - by Alan

  I was wondering if anyone can tell me if MongoDB or CouchDB are ready for a production environment. I'm now looking at these storage solutions (I'm favouring MongoDB at the moment), however these projects are quite young and so I foresee that I'm going to have to work quite hard to convince my manager that we should adopt this new technology. What I'd like to know is: 1) Who is using MongoDB or CouchDB today in a production environment? 2) How are you using MongoDB/CouchDB? 3) What problems (if any) did you come across when you adopted this new storage mechanism (and how did you overcome them)? 4) How did you deal with any migration issues that you had to deal with? 5) Do you have any good/bad experiences with either of these solutions that you'd like to share? Thanks.

• Application.Idle causes high CPU usage

  - by Neal

  Hello, I use the Application.Idle event to handle toolbar status (enable/disable) etc. quite extensively. As I'm beta testing Norton AntiVirus 2011, it brought to my attention that my app that I'm developing triggered a high CPU usage warning on at least one CPU. Sure enough, I opened the task manager and watched one of the four CPU's (quad core system) go to near 100%. I thought Application.Idle was the way to handle things when the application wasn't performing CPU tasks. Why is Application.Idle spiking the CPU? Here is how I attach to the event: AddHandler Application.Idle, AddressOf OnAppIdle Been using Application.Idle for a long time, never knew it would have this issue. Using VS 2010 .NET 4 Thank you.

• Excel Add-in memory explosion

  - by tsinik

  I wrote a small .NET add in to excel 2007 that read data from external c++ api and display it inside an excel. The task manager shows that I'm having a memory leak (the memory usage is inflate linearly up to 250MB after whitch it throws an "Excel cannot complete this task with available resources error") but the problem disappears as soon as I minimize the excel window. The api uses delegates to return data and I update it into a dictionary. another thread is updating the excel from the dictionary every second. It is unlikely that the unmanaged code is responsible of the leak. Does anybody have an idea what can cause this? 10x!

• Agile version control?

  - by Paul Dixon

  I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?

• Application disappears after starting - C++ linking managed code dll

  - by Axarydax

  Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP3 x86, and all applications linking managed code dll do not work. After starting the .exe seemingly nothing happens, no window pops up, no memory gets eaten, no task shows in task manager, nothing, nada. Event log is empty, everything is just as if the application returned to the OS right after the start. I am at loss about this, I really don't know how should I start even debugging this problem. I don't want to install VS2010 and everything onto a Windows XP box, I'd like to try something less time intensive first. This all is happening just to native C++ apps that link managed c++ DLL. Pure managed C# apps do work. Pure native C++ apps do work.

• django - order query set by postgres function

  - by thebiglife

  My initial question was here and was related to the postgres backend. http://stackoverflow.com/questions/2408965/postgres-subquery-ordering-by-subquery Now my problem has moved onwards to the Django ORM layer. I essentially want to order a query by a postgres function ('idx', taken from the above stackoverflow work) I've gone through trying to use model.objects.extra(order_by ) or simply order_by but I believe both of these need the order_by parameter to be an attribute or a field known to Django. I'm trying to think how to solve this without having to revert to using an entirely raw SQL query through a model manager.

• Blackberry 507 Erorr

  - by Haoest

  I didn't think it would be so catastrophic when I typed JavaLoader -usb wipe -a into the command line with my blackberry 8800 test device. It reboots with a 507 error that I can't get rid of. I have Blackberry Desktop Manager 4.6, which is normally what I use to upload my test apps, but this time I go to Application Loader, hitting start gives me that dialog box that shows me the list of 1 USB connection "PIN: xxx" with a password field (which I have no idea of,) then it says "connecting to boot ROM" then stops at the message: A connection to the device can not be established... Now is there a hard physical way of resetting my blackberry 8800, please?

• Cannot customize Solution Explorer project context menu in VS 2010

  - by mikoro

  I'm trying to customize that context menu which comes up when you right click the project in the Solution Explorer. When I goto: Tools - Customize - Commands - Context Menu (radio button) - Project and Solution Context Menus | Project (drop down) I get nothing in the "controls:" list. I can modify other context menus starting with "Project and Solution Context Menus" but none of them is the right one. Any ideas? Currently I have ReSharper, PowerTools and StyleCop installed, but I have installed and uninstalled bunch of other addins (dotTrace, CodeIt.Right, VisualHG, DevExpress, random stuff from Extension Manager).

• Is it good to commit files often if using Mercurial or Git?

  - by Jian Lin

  It seems that it is suggested we can commit often to keep track of intermediate changes of code we wrote… such as on hginit.com, when using Mercurial or Git. However, let's say if we work on a project, and we commit files often. Now for one reason or another, the manager wants part of the feature to go out, so we need to do a push, but I heard that on Mercurial or Git, there is no way to push individual files or a folder… either everything committed gets pushed or nothing get pushed. So we either have to revert all those files we don't want to push, or we just never should commit until before we push -- right after commit, we push?

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. does anyone know the solution?
