  • Store Observer not being called always

    - by Nixarn
    Has anyone else here experienced problems with their Store Observer class not being called always when the user for instance cancels a request (or purchases something) We just had our update that brought in app purchases go live last night, and before that we had obviously tested everything tons of times against the Sandbox and everything was working fine. Now however, when the update went live in a real environment we keep getting issues with the store. For instance, in a freshly booted iPhone / iPod, the first time you run the app, if you then try to make a purchase and then immediately cancel it from the first dialog, it seems as if the callback for the cancel is not getting called. If you then restart the app it seems as if it always works after that, or at least. Same thing with other callbacks, seems as if our store observer isn't listening as the callbacks aren't being registered on the phone. One example of this is if you purchase something, then nothing will happen (if this is the first time the app is launched at least). You get the purchase successful dialog from the app store but it seems as if our own code isn't called. If you then quit the app and restart it the callback gets called. Same problem happens if you for instance try to start a request to download all previous purchases and then immediately cancel it as the first dialog pops up, if you do that then the callback for a failed restore is not called, until you then restart the app and try it again, then it always seems to work. The way we have implemented our store observer is by creating a custom class that's implements the SKPaymentTransactionObserver interface. @interface StoreObserver : NSObject<SKPaymentTransactionObserver> In the class we have implemented the following methods: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions - (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error The way our restore process works is that if you tap on the button that allows you to download all we simply run the restoreCompletedTransactions code as follows: [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; However, the callback, restoreCompletedTransactionsFailedWithError, which has been implemented in the store observer, does not always get called when we try to cancel the request. This happens when you boot the iPhone / iPod and try this for the first time. If you after that restart the app everything works fine. The StoreObserver class is created when our app is launched, just by running the following code: pStoreObserver = [[StoreObserver alloc] init]; [[SKPaymentQueue defaultQueue] addTransactionObserver:pStoreObserver]; Has anyone else had any similar experiences? Or does anyone have any suggestions on how to solve this? As I said, in the sandbox environment everything was working fine, no issues whatsoever, but now once it's gone live we're experiencing these.

  • Struts for IBM Application Server Toolkit

    - by Timbuck
    I'm looking to build a Struts 1.2.x application for Websphere, using IBM's Application Server Toolkit. Are there any plugins available for this toolkit (it is a version of Eclipse) that are known to help with this type of development? I am new to Struts so I will also be learning about the technology as I go along, but I want to make it as painless as possible. A web search has only brought up things such as "MyEclipse", which I can't use in the corporate environment.

  • OGNL thread safety

    - by Dewfy
    I'm going to reuse OGNL library out of Struts2 scope. I have rather large set of formulas, that is why I would like to precompile all of them: Ognl.parseExpression(expressionString); But I'm not sure if precompiled expression can be used in multi-thread environment. Does anybody knows if it can be used?

    Hi, I wonder about dynamically changing of class name in .NET application. For example WindowsForms10.SysTreeView32.app.0.19fd5c7. The last string "19fd5c7" would change, but I don't know what makes it changing. Is it the version, the GUI modification, environment, OS or what? Thanks.

  • Singleton & Multithreading in Java

    - by vivek jagtap
    What is the preferred way to work with Singleton class in multithreaded environment? Suppose if I have 3 thread, and all they try to access getInstance() method of singleton class at the same time - What would happen if no synchronization is maintained? Is it good practice to use synchronized getInstance() method or use synchronized block inside getInstance(). Please advise if there is any other way out.

  • Update Statement Updates 0 Rows via the C# Winform Application?

    - by peace
    First of all, please help me out! I can not take this anymore. I could not find where the error is located. Here is my problem: I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated. Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion: public void Update(int cusID) { SqlCommand objSqlCommand = new SqlCommand(); Customer cust = new Customer(); string SQL = null; try { if ((cusID != 0)) { foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { if (SQL == null) { SQL = PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } else { SQL = SQL + ", " + PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } } else { break; } } } objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); } else { break; } } } objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); DAL.ExecuteSQL(objSqlCommand); } else { //AppEventLog.AddWarning("Primary Key is not provided for Update.") } } catch (Exception ex) { //AppEventLog.AddError(ex.Message.ToString) } } This part below: objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; generates dml: UPDATE CustomerPhone SET PhoneTypeID = @PhoneTypeID, PhoneNumber = @PhoneNumber WHERE CustomerID = @cusID AND PhoneNumber = '@phNum' @PhoneTypeID and @PhoneNumber are gotten from two properties. We assigned the value to these properties in the presentation layer from the user input text box. The portion below where fetches the values: objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); The code below fills the values of WHERE: objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); The final code should look as: UPDATE CustomerPhone SET PhoneTypeID = 7, PhoneNumber = 999444 WHERE CustomerID = 500 AND PhoneNumber = '911'; Phone type id is 7 - user value that is taken from text box Phone number is 999444 - user value that is taken from text box The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated! I wonder why?

  • Windows freezes, showing a random color or pattern

    - by Manu
    I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

  • Best practices for QA / testing in an Agile (Scrum+XP) team?

    - by Srirangan
    Hey guys, We're getting a QA for the first time in our project. We're not sure how to best use him. We work in an Agile environment. Pair programming, user stories, short sprints (two weeks), daily stand-ups, retrospectives, planning meetings, quick releases etc. One obviously way to use a tester is to verify bugs fixes and user stories every sprint. Are there any better ways for an Agile team to utilize a tester. Thanks, Sri

  • Adding a clustered index to a SQL table: what dangers exist for a live production system?

    - by MoSlo
    Right, keep in mind i need to describe this by abstracting all possible confidential info: I've been put in charge of a 10-year old transactional system of which the majority business logic is implemented at database level (triggers, stored procedures etc). Win2000 server, MSSQL 2000 Enterprise. No immediate plans for replacing/updating the system are being considered :( The core process is a program that executes transactions - specifically, it executes a stored procedure with various parameters, lets call it sp_ProcessTrans. The program executes the stored procedure at asynchronous intervals. By itself, things work fine. But there are 30 instances of this program on remotely located workstations, all of them asynchronously executing sp_ProcessTrans and then retrieving data from the SQL server (execution is pretty regular - ranging 0 to 60 times a minute, depending on what items the program instance is responsible for) . Performance of the system has dropped considerably with 10 yrs of data growth: the reason is the deadlocks and specifically deadlock wait times. The deadlock is on the Employee table. I have discovered: In sp_ProcessTrans' execution, it selects from an Employee table 7 times (dont ask) The select is done on a field that is NOT the primary key No index exists on this field. Thus a table scan is performed. 7 times. per transaction So the reason for deadlocks is clear. I created a non-unique ordered clustered index on the field (field looks good, almost unique, NUM(7), very rarely changes). Immediate improvement in the test environment. The problem is that i cannot simulate the deadlocks in a test environment (I'd need 30 workstations; i'd need to simulate 'realistic' activity on those stations, so visualization is out). I need to know if i must schedule downtime. Creating an index shouldn't be a risky operation for MSSQL, but is there any danger (data corruption in transactions/select statements/extra wait time etc) to create this field index on the production database while the transactions are still taking place? (although i can select a time when transactions are fairly quiet through the 30 stations) Are there any hidden dangers i'm not seeing (not looking forward to needing to restore the DB if something goes wrong, restoring would take a lot of time with 10yrs of data).

  • Can I filter multiple column headers to display subheadings of each in Excel?

    - by Gigi
    I can't seem to find this anywhere... it may not even be possible without coding? I have a spreadsheet containing more than one heading in a single column. These headings are identified with blue background and white font. Each of these headings have items listed below them. These "subheadings" are smaller, auto-black font and no fill background. Currently I have to scroll down the spreadsheet to view all headers and their contents. How do I create a filter that would allow me to sort on whichever header I want, so that (only) the contents of that particular header are displayed?

  • Android - doInBackground() error in AsyncTask

    - by AimanB
    What my app here basically does is it captures a photo or import from gallery, and when the Upload button is pressed, the image will be uploaded to a localhost server. Before I implemented AsyncTask into the process, it doesn't have any problem uploading whatsoever. Now that I've put AsyncTask, everything went wrong. I don't know which part that I do wrong in this phase. This is what logcat shows when I try to upload an image file: 10-28 17:23:25.989: E/AndroidRuntime(3356): FATAL EXCEPTION: AsyncTask #5 10-28 17:23:25.989: E/AndroidRuntime(3356): java.lang.RuntimeException: An error occured while executing doInBackground() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$3.done(AsyncTask.java:299) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:352) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.setException(FutureTask.java:219) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:239) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:230) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.lang.Thread.run(Thread.java:856) 10-28 17:23:25.989: E/AndroidRuntime(3356): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:197) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:111) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast$TN.<init>(Toast.java:324) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.<init>(Toast.java:91) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.makeText(Toast.java:238) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:268) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:1) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$2.call(AsyncTask.java:287) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:234) This is my code for the Upload activity: public class UploadImageActivity extends Activity implements OnItemSelectedListener { InputStream inputStream;

  • Cannot SSH into Virtual Machine

    I am running a CentOS VM on my desktop that I use for development testing when coding in python. At my school I have a dedicated IP setup for the VM and my desktop so I never seem to have an issue ssh'ing from desktop into VM. I am now at home for winter break and cannot seem to SSH into the VM using the local ip address behind my router, the external IP with port 22 forwarded to my VM, or anything. Strangely enough I can ssh into my production server and then fromt here ssh into the VM, but not from my desktop to the VM directly What should I do to get this to work? Thanks
