  • Array returning Null values

    - by Nick Gibson
    Dunno why it is...heres the coding for it. http://pastebin.org/301343 I know theres a lot of repetitiveness in the coding...but its because the arrays were retuning null so I got tired of messing with them. Everything works until it reaches line 224, which returns null values.

  • Null Validation on EditText box in Alert Dialog - Android

    - by LordSnoutimus
    Hi, I am trying to add some text validation to an edit text field located within an alert dialog box. It prompts a user to enter in a name. I want to add some validation so that if what they have entered is blank or null, it does not do anything apart from creating a Toast saying error. So far I have: AlertDialog.Builder alert = new AlertDialog.Builder(this); alert.setTitle("Record New Track"); alert.setMessage("Please Name Your Track:"); // Set an EditText view to get user input final EditText trackName = new EditText(this); alert.setView(trackName); alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { String textString = trackName.getText().toString(); // Converts the value of getText to a string. if (textString != null && textString.trim().length() ==0) { Context context = getApplicationContext(); CharSequence error = "Please enter a track name" + textString; int duration = Toast.LENGTH_LONG; Toast toast = Toast.makeText(context, error, duration); toast.show(); } else { SQLiteDatabase db = waypoints.getWritableDatabase(); ContentValues trackvalues = new ContentValues(); trackvalues.put(TRACK_NAME, textString); trackvalues.put(TRACK_START_TIME,tracktimeidentifier ); insertid=db.insertOrThrow(TRACK_TABLE_NAME, null, trackvalues); } But this just closes the Alert Dialog and then displays the Toast. I want the Alert Dialog to still be on the screen. Thanks

  • SQL Server Express 2005 Merge Replication using RMO causes Null Reference exception

    - by Craig Shearer
    I'm trying to use RMO to programmatically perform merge synchronization. I've basically copied the SQL Server example code, as follows: // Create a connection to the Subscriber. ServerConnection conn = new ServerConnection(subscriberName); MergePullSubscription subscription; try { // Connect to the Subscriber. conn.Connect(); // Define the pull subscription. subscription = new MergePullSubscription(subscriptionDbName, publisherName, publicationDbName, publicationName, conn, false); // If the pull subscription exists, then start the synchronization. if (subscription.LoadProperties()) { // Check that we have enough metadata to start the agent. if (subscription.PublisherSecurity != null || subscription.DistributorSecurity != null) { subscription.SynchronizationAgent.Synchronize(); } else { throw new ApplicationException("There is insufficent metadata to " + "synchronize the subscription. Recreate the subscription with " + "the agent job or supply the required agent properties at run time."); } } else { // Do something here if the pull subscription does not exist. throw new ApplicationException(String.Format( "A subscription to '{0}' does not exist on {1}", publicationName, subscriberName)); } } catch (Exception ex) { // Implement appropriate error handling here. throw new ApplicationException("The subscription could not be " + "synchronized. Verify that the subscription has " + "been defined correctly.", ex); } finally { conn.Disconnect(); } I've got the server merge publication defined correctly, but when I run the above code, I get a null reference exception on the call to: subscription.SynchronizationAgent.Synchronize(); The stack trace is as follows: at Microsoft.SqlServer.Replication.MergeSynchronizationAgent.StatusEventSinkMethod(String message, Int32 percent, Int32* returnValue) at Test.ConsoleTest.Program.SynchronizePullSubscription() in F:\Visual Studio Projects\Test\source\Test.ConsoleTest\Program.cs:line 124 It seems, from the stack trace, like something to do with the Status event, but I don't have a handler defined, and defining one makes no difference.

  • malloc: error checking and freeing memory

    - by yCalleecharan
    Hi, I'm using malloc to make an error check of whether memory can be allocated or not for the particular array z1. ARRAY_SIZE is a predefined with a numerical value. I use casting as I've read it's safe to do so. long double *z1 = (long double *)malloc(sizeof (long double) * ARRAY_SIZE); if(z1 == NULL){ printf("Out of memory\n"); exit(-1); } The above is just a snippet of my code, but when I add the error checking part (contained in the if statement above), I get a lot of compile time errors with visual studio 2008. It is this error checking part that's generating all the errors. What am I doing wrong? On a related issue with malloc, I understand that the memory needs to be deallocated/freed after the variable/array z1 has been used. For the array z1, I use: free(z1); z1 = NULL; Is the second line z1 = NULL necessary? Thanks a lot...

  • Backup program for Windows using non-proprietary format?

    - by Cristi Diaconescu
    I'm looking at the various local backup programs for windows, and I was wondering which of them use a non-proprietary backup format? By non-proprietary, I mean I want to be able to access at least the latest version of the backed up files either directly, or by using an open-standard format like zip/7z/rdiff... The other thing I'm looking for in a backup program is the ability to create incremental backups. What I have found so far: SyncBack copies files as-is, using separate directories for versioning pretty much the same for all the 'roll you own' task scheduler + rsync/xcopy32/robocopy/MS SyncToy/etc solutions GFI Backup appears to be using Zip files, at least in their 'Business' version, not sure about the free 'Home' version. Didn't try it yet, but it's next on my list. Mozy (!) supports local backup starting with v 2.0 and basically provides a 2nd local copy on a separate partition. Subjectively, it feels slow and resource intensive (I think it took more than a week to finish the first local backup of ~ 300 GB), and does not appear to offer file versioning (arguably, you can get older file versions online). On the positive side, it looks like the local backup is integrated in the restore process which was traditionally a masochistic experience (and this goes for any online backup provider). Other suggestions? I favor ease of use over tons of options (e.g. SyncBack is very flexible but it offers sooo many ways to shoot yourself in the foot...)

  • Iphone SQLite Databse with german umlauts results in NULL value

    - by Daniel
    Hi guys, I'm quite new to the Iphone development and after search for an answer for 3 hours now, I hope that you guys can give me a hand. My problem is that I have a SQLite Database with german umlauts. Looking at it with a SQLite browser tool shows me that the data is stored with german umlauts, correctly. But selecting fields with german umlauts in it results in a NULL value. I'm already using "stringWithUTF8String", so I don't get the point where the problem is placed. Here is my code: -(void) readSearchFromDatabase { searchFlag = YES; // Setup the database object sqlite3 *database; // Init the SCode Array searchSCodes = [[NSMutableArray alloc] init]; // Open the database from the users filessytem if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) { NSString *wildcard =@"%"; // Setup the SQL Statement and compile it NSString *sql = [NSString stringWithFormat:@"SELECT * FROM scode WHERE ta LIKE '%@%@%@' OR descriptionde LIKE '%@%@%@' OR descriptionen LIKE '%@%@%@'", wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard]; //Creating a const char SQL Statement especially for SQLite const char *sqlStatement = [sql UTF8String]; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { // Loop through the results and add them to the feeds array while(sqlite3_step(compiledStatement) == SQLITE_ROW) { // Read the data from the result row NSString *aTa = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; NSString *aReport = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]; NSString *aDescriptionDE = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; NSString *aDescriptionEN = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)]; //Results a NULL value NSLog(@"Output: %@", aDescriptionDE); // Create a new SCode object with the data from the database SCode *searchSCode = [[SCode alloc] initWithTa:aTa report:aReport descriptionDE:aDescriptionDE descriptionEN:aDescriptionEN]; // Add the SCode object to the SCodes Array [searchSCodes addObject:searchSCode]; [searchSCode release]; } } // Release the compiled statement from memory sqlite3_finalize(compiledStatement); } sqlite3_close(database); }

  • Writing files in App_Data causes tempdata to be null

    - by RAMX
    I have a small asp.net MVC 1 web app that can store files and create directories in the App_Data directory. When the write operation succeeds, I add a message to the tempdata and do a redirectToRoute. The problem is that the tempdata is null when the action is executed. If i write the files in a directory outside of the web applications root directory, the tempdata is not null and everything works correctly. Any ideas why writing in the app_data seems to clear the tempdata ? edit: if DRS.Logic.Repository.Manager.CreateFile(path, hpf, comment) writes in the App_Data, TempData will be null in the action being redirected to. if it is a directory out of the web app root it is fine. No exceptions are being thrown. [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(int id, string path, FormCollection form) { ViewData["path"] = path; ViewData["id"] = id; HttpPostedFileBase hpf; string comment = form["FileComment"]; hpf = Request.Files["File"] as HttpPostedFileBase; if (hpf.ContentLength != 0) { DRS.Logic.Repository.Manager.CreateFile(path, hpf, comment); TempData["notification"] = "file was created"; return RedirectToRoute(new { controller = "File", action ="ViewDetails", id = id, path = path + Path.GetFileName(hpf.FileName) }); } else { TempData["notification"] = "No file were selected."; return View(); } }

  • document.getElementById() returns null when using mozrepl (but not in firebug)

    - by teamonkey
    I'm trying to use the mozrepl Firefox extension to give me a Javascript REPL from within emacs. I think I've got it set up correctly. I can interact with the REPL from emacs and can explore the document pretty much as described in the tutorial pages. The problem comes when I try to do something really simple, like get a context to a canvas element: repl> document.getElementById("mycanvas").getContext("2d") !!! TypeError: document.getElementById("mycanvas") is null Details: message: document.getElementById("mycanvas") is null fileName: chrome://mozrepl/content/repl.js -> file:///C:/Users/teamonkey/AppData/Roaming/Mozilla/Firefox/Profiles/chfdenuz.default/mozrepl.tmp.js lineNumber: 1 stack: @chrome://mozrepl/content/repl.js -> file:///C:/Users/teamonkey/AppData/Roaming/Mozilla/Firefox/Profiles/chfdenuz.default/mozrepl.tmp.js:1 name: TypeError It's not just that particular instance: any call to getElementById will just return null. If I start up firebug I can enter the same thing and it will return a valid context, but I'd really like to get the REPL working in emacs. I don't think this is a bug but I've probably not configured mozrepl correctly. Can anyone help? Mozrepl 1.0, Firefox 3.6

  • geocoder.getFromLocationName returns only null

    - by test
    Hello, I am going out of my mind for the last 2 days with an IllegalArgumentException error i receive in android code when trying to get a coordinates out of an address, or even reverse, get address out of longitude and latitude. this is the code, but i cannot see an error. is a standard code snippet that is easily found on a google search. public GeoPoint determineLatLngFromAddress(Context appContext, String strAddress) { Geocoder geocoder = new Geocoder(appContext, Locale.getDefault()); GeoPoint g = null; try { System.out.println("str addres: " + strAddress); List<Address> addresses = geocoder.getFromLocationName(strAddress, 5); if (addresses.size() > 0) { g = new GeoPoint((int) (addresses.get(0).getLatitude() * 1E6), (int) (addresses.get(0).getLongitude() * 1E6)); } } catch (Exception e) { throw new IllegalArgumentException("locationName == null"); } return g; } These are the permissions from manifest.xml file: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /> I do have the Google Api key declared too: <uses-library android:name="com.google.android.maps" /> From the code snippet above, geo coder is not null, neither is the address or appContext, and i stumble here: geocoder.getFromLocationName(strAddress, 5); I did a lot of google searching and found nothing that worked, and the most important info i found is this: ""The Geocoder class requires a backend service that is not included in the core android framework." Sooo, i am confuzed now. What do I have to call, import, add, use in code.... to make this work? I am using Google Api2.2, Api level 8. If somebody has found a solution for this, or a pointer for documentation, something that i didn't discover, please let us know. Thank you for your time.

  • File sharing for small, distributed, non-technical, non-profit organization?

    - by mnmldave
    Problem: I've started volunteering for a small non-profit with fewer than five non-technical Windows users who need to share 20-30GB of files (Office documents, images, PDFs, etc.) amongst themselves online. Background: The users are accustomed to a Windows network share on a machine that backed up their data locally. An on-site "disaster" has forced them to work from their homes for awhile and to re-evaluate their file sharing needs (office was located in an old building with obvious electrical issues, etc.). Access to time from volunteers with IT experience seems to be difficult. Demonstrably minimizing energy consumption is a nice-to-have. I'm currently considering Jungle Disk (a Desktop account shared amongst the handful of employees since their TOS and my inquiries to their helpdesk seem to indicate this is permissible). It appears easy-to-use, inexpensive, secure, has backup functionality, and can scale to accomodate more data when needed. I've not used it myself though (have only used Dropbox for personal use) and systems isn't my area of expertise, so am worried I might be jumping on a bandwagon. That said, any suggestions, thoughts or similar experiences would be really appreciated.

  • Unit test for Web Forms MVP presenter has a null Model

    - by jacksonakj
    I am using Web Forms MVP to write an DotNetNuke user control. When the 'SubmitContactUs' event is raised in my unit test the presenter attempts to set the 'Message' property on the Modal. However the View.Modal is null in the presenter. Shouldn't the Web Forms MVP framework automatically build a new View.Model object in the presenter? It could be that the 'Arrange' portion of my test is missing something that the presenter needs. Any help would be appreciated. Here is my test: using System; using AthleticHost.ContactUs.Core.Presenters; using AthleticHost.ContactUs.Core.Views; using Xunit; using Moq; namespace AthleticHost.ContactUs.Tests { public class ContactUsPresenterTests { [Fact] public void ContactUsPresenter_Sets_Message_OnSubmit() { // Arrange var view = new Mock<IContactUsView>(); var presenter = new ContactUsPresenter(view.Object); // Act view.Raise(v => v.Load += null, new EventArgs()); view.Raise(v => v.SubmitContactUs += null, new SubmitContactUsEventArgs("Chester", "Tester", "[email protected]", "http://www.test.com", "This is a test of the emergancy broadcast system...")); presenter.ReleaseView(); // Assert Assert.Contains("Chester Tester", view.Object.Model.Message); } } }
