• Android SQLiteConstraintException: error code 19: constraint failed

  - by Tom D

  I've seen other questions about this exception, but all of them seem to be resolved with the solution that a row with the primary key specified already exists. This doesn't seem to be the case for me. I have tried replacing all single quotes in my strings with double quotes, but the same problem occurs. I'm trying to insert a row into the Settings table of the SQLite database I've created by doing the following: db.execSQL("DROP TABLE IF EXISTS "+Settings.SETTINGS_TABLE_NAME + ";"); db.execSQL(CREATE_MEDIA_TABLE); db.execSQL(CREATE_SETTINGS_TABLE); Cursor c = getAllSettings(); //If there isn't already a settings row, create a row full of defaults if(c.getCount()==0){ ContentValues cv = new ContentValues(); cv.put(Settings.SETTING_UNIQUE_ID, "'"+Settings.uniqueID+"'"); cv.put(Settings.SETTING_DEVICE_ID, Settings.SETTING_DEVICE_ID_DEFAULT); cv.put(Settings.SETTING_CONNECTION_PREFERENCE, Settings.SETTING_CONNECTION_PREFERENCE_DEFAULT); cv.put(Settings.SETTING_AD_HOC_ENABLED, Settings.SETTING_AD_HOC_ENABLED_DEFAULT); cv.put(Settings.SETTING_SERVER_ADDRESS, Settings.SETTING_SERVER_ADDRESS_DEFAULT); cv.put(Settings.SETTING_RECORDING_MODE, Settings.SETTING_RECORDING_MODE_DEFAULT); cv.put(Settings.SETTING_PREVIEW_ENABLED, Settings.SETTING_PREVIEW_ENABLED_DEFAULT); cv.put(Settings.SETTING_PICTURE_RESOLUTION_X, Settings.SETTING_PICTURE_RESOLUTION_X_DEFAULT); cv.put(Settings.SETTING_PICTURE_RESOLUTION_Y, Settings.SETTING_PICTURE_RESOLUTION_Y_DEFAULT); cv.put(Settings.SETTING_VIDEO_RESOLUTION_X, Settings.SETTING_VIDEO_RESOLUTION_X_DEFAULT); cv.put(Settings.SETTING_VIDEO_RESOLUTION_Y, Settings.SETTING_VIDEO_RESOLUTION_Y_DEFAULT); cv.put(Settings.SETTING_VIDEO_FPS, Settings.SETTING_VIDEO_FPS_DEFAULT); cv.put(Settings.SETTING_AUDIO_BITRATE_KBPS, Settings.SETTING_AUDIO_BITRATE_KBPS_DEFAULT); cv.put(Settings.SETTING_STORE_TO_SD, Settings.SETTING_STORE_TO_SD_DEFAULT); cv.put(Settings.SETTING_STORAGE_LIMIT_MB, Settings.SETTING_STORAGE_LIMIT_MB_DEFAULT); this.db.insert(Settings.SETTINGS_TABLE_NAME, null, cv); } The CREATE_SETTINGS_TABLE string is defined as the following: private static String CREATE_SETTINGS_TABLE = "CREATE TABLE IF NOT EXISTS " + Settings.SETTINGS_TABLE_NAME + "(" + Settings.SETTING_UNIQUE_ID + " TEXT NOT NULL PRIMARY KEY, " + Settings.SETTING_DEVICE_ID + " TEXT NOT NULL , " + Settings.SETTING_CONNECTION_PREFERENCE + " TEXT NOT NULL CHECK("+Settings.SETTING_CONNECTION_PREFERENCE+" IN("+Settings.SETTING_CONNECTION_PREFERENCE_ALLOWED+")), " + Settings.SETTING_AD_HOC_ENABLED + " TEXT NOT NULL CHECK("+Settings.SETTING_AD_HOC_ENABLED+" IN("+Settings.SETTING_AD_HOC_ENABLED_ALLOWED+")), " + Settings.SETTING_SERVER_ADDRESS + " TEXT NOT NULL, " + Settings.SETTING_RECORDING_MODE + " TEXT NOT NULL CHECK("+Settings.SETTING_RECORDING_MODE+" IN("+Settings.SETTING_RECORDING_MODE_ALLOWED+")), " + Settings.SETTING_PREVIEW_ENABLED + " TEXT NOT NULL CHECK("+Settings.SETTING_PREVIEW_ENABLED+" IN("+Settings.SETTING_PREVIEW_ENABLED_ALLOWED+")), " + Settings.SETTING_PICTURE_RESOLUTION_X + " TEXT NOT NULL, " + Settings.SETTING_PICTURE_RESOLUTION_Y + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_RESOLUTION_X + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_RESOLUTION_Y + " TEXT NOT NULL, " + Settings.SETTING_VIDEO_FPS + " TEXT NOT NULL, " + Settings.SETTING_AUDIO_BITRATE_KBPS + " TEXT NOT NULL, " + Settings.SETTING_STORE_TO_SD + " TEXT NOT NULL CHECK("+Settings.SETTING_STORE_TO_SD+" IN("+Settings.SETTING_STORE_TO_SD_ALLOWED+")), " + Settings.SETTING_STORAGE_LIMIT_MB + " TEXT NOT NULL )"; However, when I execute my insert, I always get: 03-19 19:37:36.974: ERROR/Database(386): Error inserting server_address='0.0.0.0' storage_limit='-1' connection='none' preview_enabled='0' sd_enabled='1' video_fps='15' audio_bitrate='96' device_id='-1' recording_mode='none' picture_resolution_x='-1' picture_resolution_y='-1' unique_id='000000000000000' adhoc_enable='0' video_resolution_x='320' video_resolution_y='240' 03-19 19:45:34.284: ERROR/Database(446): android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed It seems as if all the columns in my insert are not null.

• A standard event messaging system with AJAX?

  - by Gutzofter

  Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?

• What's the best way to run a process remotely with capturing the output ?

  - by Homam

  Hi all, I have a windows service responsible for running processes on a remote machine with capturing the output, I googled for that and read a lot of articles and threads, I found two ways: 1) using WMI for call the remote process like this example: http://www.codeproject.com/KB/cs/EverythingInWmi02.aspx 2) using the PsExec tool by System.Diagnostic.Process class ever way of these has many problems, the WMI doesn't support returning the output and doesn't support "WaitingToExit" It just call the process and return the PId, and the PsExec couldn't capture the output programmatically by System.Diagnostic.Process in a clear way, I found only workarounds like redirect the output to a file then read the redirected file..etc, I need a real solution please

• Error when starting an activity

  - by Adam

  I'm starting an activity when a button is pressed, and normally (in other apps) haven't had an issue. But when I press the button in this app, I get an "unable to marshal value" error. Exact(ish) error from LogCat: 03-22 02:49:02.883: WARN/System.err(252): java.lang.RuntimeException: Parcel: unable to marshal value {CLASSNAME}@44dcf1b8 I feel that this might be related to the extra that I'm passing to the intent. I'm passing an ArrayList as a serializable to this new intent. My concern is that the data structure that the ArrayList contains isn't being serialized (as it's a personal data structure). Is the array list content data structure causing this? Something else that I'm missing?

• Windows Phone 7 HttpRequest Unable to see true Error Code and response details

  - by Bob

  I have to call a somewhat broken API from a Windows Phone 7 application. The API returns a 302 error and a cookie to the authentication request. I've tried every way I've been able to find in the MSDN documentation for using ClientHTTP instead of BrowserHTTP (registering the prefix, using the call to explicitly create a ClientHTTP using Request), but the 302 is getting translated to a 404 and I'm not seeing the cookies on the response. I've tried a WebClient, I've tried an HttpRequest and it is always the translated error message. If I allocate a CookieContainer for the HttpRequest, I get a null argument exception when the client stack is parsing the returned message. I can see that the response is coming back as expected via Fiddler.

• Selectedindex in listview, throwing up an error!

  - by Luke

  Hey guys, the following code shows what i am trying to do. private void btnEdit_Click(object sender, EventArgs e) { iDeliverySelected = lstDeliveryDetails.SelectedIndex; bool addEdit = false; } The selectedindex is throwing up the following error.. 'System.Windows.Forms.ListView' does not contain a definition for 'SelectedIndex' and no extension method 'SelectedIndex' accepting a first argument of type 'System.Windows.Forms.ListView' could be found (are you missing a using directive or an assembly reference?) Any ideas why? First time I have tried to use SelectedIndex, not sure if i am using it correctly?

• VB 2010 Express - Debugger is not breaking on errors, Sub producing error simply terminates

  - by hamlin11

  I'm using VB 2010 Express. When an error occurs in the form load function, the form load function simply terminates. Then, when I click on one of my buttons, the button click sub also terminates if it has an error. I can wrap the code that produces the errors in try/catch blocks, but I'd very much rather the debugger to throw an immediate break point (like usual) or at least exit the program. It's making it very difficult to program, not knowing whether or not previous Subs executed fully. Any thoughts on what might be going on? Thanks

• Error on Access database: Permission denied: 'CreateObject'

  - by elixireu

  Hi, I am migrating a website over to a new server, its in ASP and uses several Access databases, the site and CMS can read, display the data, and even edit and update existing data entries, but when I want to add a new entry, I get an error... Microsoft VBScript runtime error '800a0046' Permission denied: 'CreateObject' /padp2010d/ads_tradetracker.asp, line 11 There seems to be no passwords on the databases, I have set up and tested the ODBC Data Sources and they are working fine.

• Visual Studios Team System 2008 Code Coverage Window Closes

  - by ThoughtCrhyme

  Trying to run the code coverage tool in Visual Studios for a set of unit tests. Adam from Think First, Code Later has had the same problem: I wanted to get the code coverage metrics for the project. Naturally, I fire up the solution in Visual Studio 2008, go to the Test menu, click Edit Test Run Configurations, and click Local Test Run. I then click Code Coverage to turn on code coverage for a given assembly and POOF the Local Test Run Configraution window just disappears. He recommends installing this hotfix to fix the problem, however a) when I run that hotfix I get the message “None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup.” and b) there is no Silverlight in our solution. Any other ideas for a fix?

• Questions about using git as a backend storage system

  - by XO

  New to git here... I want to commit my personal file share to a git repo (text, docs, images etc). As I make modifications to various files over time, telling git about them along the way, how do go about things so I can: Get out of the business of traditional fulls/incrementals. Be able to do a point-in-time file or full clone restore. Basically, I want something granular, such that, if I make an edit to a file 5 times on a particular day. I will have 5 versions of that file that I can refer back to- forever. Or even just derive the a full copy of everything the way it looked on that particular day. I am currently using rsync for remote incremental syncs (no file versioning).

• Please recommend good books for telemetry / SCADA system design & programming

  - by Mawg

  I am looking at several projects, all with roughly the same fucntionality. Some instruments collect some data (or control some functionality). They commmunicate by Internet (Etehrnet/wifi/GPRS/sasatellite) with a databse server which stores the measurements and provides a browser based means of qeurying the data, prodcuing reports, etc (and possibly also allows control of the remote equipment). Can anyone recommend a good book describing an approach to developing such a software architecture, keeping it generic, which tools, languages. test methods, etc to use? (note to self: ask a similar question about possible existing frameworks)

• Common Lisp condition system for transfer of control

  - by Ken

  I'll admit right up front that the following is a pretty terrible description of what I want to do. Apologies in advance. Please ask questions to help me explain. :-) I've written ETLs in other languages that consist of individual operations that look something like: // in class CountOperation IEnumerable<Row> Execute(IEnumerable<Row> rows) { var count = 0; foreach (var row in rows) { row["record number"] = count++; yield return row; } } Then you string a number of these operations together, and call The Dispatcher, which is responsible for calling Operations and pushing data between them. I'm trying to do something similar in Common Lisp, and I want to use the same basic structure, i.e., each operation is defined like a normal function that inputs a list and outputs a list, but lazily. I can define-condition a condition (have-value) to use for yield-like behavior, and I can run it in a single loop, and it works great. I'm defining the operations the same way, looping through the inputs: (defun count-records (rows) (loop for count from 0 for row in rows do (signal 'have-value :value `(:count ,count @,row)))) The trouble is if I want to string together several operations, and run them. My first attempt at writing a dispatcher for these looks something like: (let ((next-op ...)) ;; pick an op from the set of all ops (loop (handler-bind ((have-value (...))) ;; records output from operation (setq next-op ...) ;; pick a new next-op (call next-op))) But restarts have only dynamic extent: each operation will have the same restart names. The restart isn't a Lisp object I can store, to store the state of a function: it's something you call by name (symbol) inside the handler block, not a continuation you can store for later use. Is it possible to do something like I want here? Or am I better off just making each operation function explicitly look at its input queue, and explicitly place values on the output queue?
