  • Clean way to display/hide a bunch of buttons based on a ComboBox selection

    - by John at CashCommons
    I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid. Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing. Is there a way to do this? Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons. Thanks in advance as always!

  • Why my buttons OnClick event fails to fire?

    - by Pentium10
    I have an activity, where the ListView holds customized linear layout elements for each row. One of the rows has a button defined as: <Button android:text="Pick a contact" android:id="@+id/btnPickContact" android:layout_width="wrap_content" android:gravity="center_vertical" android:layout_height="wrap_content"></Button> Then in java, I have this code: ((Button) row.findViewById(R.id.btnPickContact)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); act.startActivityForResult(intent, PICK_CONTACT); } }); In this setup the event fails to start. Also I've tried by implementing the interface: @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); startActivityForResult(intent, PICK_CONTACT); } still no luck, the event doesn't fire. What to do?

  • IBOutlet instances are (null) after loading from NIB

    - by Zach
    I am working on an iPhone app and am getting (null) references to IBOutlet fields in my controller. I have a UIViewController subclass that is set as the File's Owner in my XIB. I have a set of UI elements that are wired into the controller. After loading from NIB and attempting to set properties on those UI elements, I find that they are (null). To clarify, some code: ExpandSearchPageController.h: @interface ExpandSearchPageController : UIViewController { IBOutlet UITextView * completeMessageView; } -(void)checkTextField; @property (nonatomic, retain) IBOutlet UITextView * completeMessageView; ExpandSearchPageController.m: @implementation ExpandSearchPageController @synthesize completeMessageView; -(void)checkTextField { NSLog(@"text field: %@",completeMessageView); } ExpandSearchPageController is set as the File's Owner for ExpandSearchPage.xib. ExpandSearchPage.xib's UITextView is wired to the completeMessageView. When I call ExpandSearchPageController * searchExpanderPage = [[ExpandSearchPageController alloc] initWithNibName:@"ExpandSearchPage" bundle:[NSBundle mainBundle]]; [searchExpanderPage checkTextField]; the result is "text field: (null)" Sorry if this is a total newb question, but I guess I'm still a newb at iPhone programming! Thanks in advance!

  • Why am I getting two section headers on this grouped table?

    - by Andy
    I'm sure this is some easy-to-fix issue that I've missed, but I can't figure it out. I've got a grouped table view with 3 sections. I'm using the following code to generate section headers: -(NSString*)tableView:(UITableView*)tableView titleForHeaderInSection:(NSInteger)section { if (section == 0) { NSString *header = @"Header 1"; return header; } if (section == 1) { NSString *header = @"Header 2"; return header; } else { NSString *header = @"Header 3"; return header; } } When my table is displayed, there are two headers for each section - one with white text on a gray bar that stretches across the screen (like the letter separators in the Contacts app), and one in gray text on the table background (which is the one I want). Both headers have identical text. Where is the first header coming from?

  • iPhone Gps logging inaccurate

    - by Martijn
    I'm logging gps points during a walk. Below it shows the function that the coordinates are saved each 5 seconds. i Did several tests but i cannot get the right accuracy i want. (When testing the sky is clear also tests in google maps shows me that the gps signal is good). here is the code: -(void)viewDidAppear:(BOOL)animated{ if (self.locationManager == nil){ self.locationManager = [[[CLLocationManager alloc] init] autorelease]; locationManager.delegate = self; // only notify under 100 m accuracy locationManager.distanceFilter = 100.0f; locationManager.desiredAccuracy= kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; } } - start logging [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(getData) userInfo:nil repeats:YES]; </code> <code> -(void)getData{ int distance; // re-use location. if ([ [NSString stringWithFormat:@"%1.2f",previousLat] isEqualToString:@"0.00"]){ // if previous location is not available, do nothing distance = 0; }else{ CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:previousLat longitude:previousLong]; CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:latGlobal longitude:longGlobal]; distance = [loc1 getDistanceFrom: loc2]; } // overwrite latGlobal with new variable previousLat = latGlobal; previousLong = longGlobal; // store location and save data to database // this part goes ok } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // track the time to get a new gps result (for gps indicator orb) lastPointTimestamp = [newLocation.timestamp copy]; // test that the horizontal accuracy does not indicate an invalid measurement if (newLocation.horizontalAccuracy < 0) return; // test the age of the location measurement to determine if the measurement is cached // don't rely on cached measurements NSTimeInterval locationAge = -[newLocation.timestamp timeIntervalSinceNow]; if (locationAge > 5.0) return; latGlobal = fabs(newLocation.coordinate.latitude); longGlobal= fabs(newLocation.coordinate.longitude); } I have taken a screenshot of the plot results (the walk takes 30 minutes) and an example of what i'am trying to acomplish: http://www.flickr.com/photos/21258341@N07/4623969014/ i really hope someone can put me in the right direction.

  • Create a view like Tweetie's User Profile view

    - by Graeme
    Hi, I'm just wondering if anyone has any idea on how you can create a view that looks like the user profile view in apps like Tweetie, where there are seemingly multiple tables with a couple of normal (straight up and down tables) and then two rows of six cells, which in Tweeties case have the number of followers, following etc. I'm trying to make a similar view for my app, but can't seem to find out the best way to create it. Any tutorials, advice etc. would be appreciated. Thanks. P.S. Here's a picture of the view which I'm trying to recreate.

  • Why does addSubview load the view asynchronously

    - by moshe
    I have a UIView that I want to load when the user clicks a button. There happens to be some data processing that happens as well after I call addSubview that involves parsing an XML file retrieved from the web. The problem is the view doesn't show up until after the data processing even if addSuview is called first. I think I'm missing something here, can anyone help? Code: I have a "Loading..." view I'm adding as a custom modal (meaning I'm not using the modalViewController). This action is linked to a button in the navigationController. - (IBAction)parseXml:(id)sender { LoadingModalViewController *loadingModal = [[LoadingModalViewController alloc] initWithNibName:@"LoadingModalViewController" bundle:nil]; [navigationController.view addSubview:loadingModal.view]; [xmlParser parse]; }

  • Andriod Spinner not displaying list items.

    - by user300339
    I think I am going crazy right now. I am trying to create a spinner populated by a datatable but for some reason the dropdown list items text is not being displayed. I have looked all over and have seen other posts with people having this same problem. Can anyone help?? speciesList = (Spinner) findViewById(R.id.speciesList); spinnerCursor = nsfdb.fetchAllSpecies(); startManagingCursor(spinnerCursor); //String []cArrayList = new String[]{"dog", "cat", "horse", "other"}; String[] from = new String[]{"species"}; int[] to = new int[]{R.id.text1}; SimpleCursorAdapter locations = new SimpleCursorAdapter(this, R.layout.loc_row, spinnerCursor, from, to); locations.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); speciesList.setAdapter(locations); The spinner gets created just fine and is populated with 4 items but whenever I click on the spinner I see 4 items with no text and just radiobuttons. If I select any of them I am getting the correct selected item value but there is just no data displayed.

  • sqlite issue using WHERE statement on a varchar field in Objective-C

    Hi, I have this sql statement SELECT * FROM Language WHERE LanguageCode=? where LanguageCode is a varchar(2).

Is there any issue filtering by a varchar field using WHERE statement? Thanks
