  • How to restrict this function from execution in android? Please help

    - by andyfan
    This code is present in one of this activity. I want to restrict addJoke() function from executing if the String variable new_joke is null, has no text or contains just spaces. Here is code protected void initAddJokeListeners() { // TODO m_vwJokeButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { //Implement code to add a new joke here... String new_joke=m_vwJokeEditText.getText().toString(); if(new_joke!=null&&new_joke!=""&&new_joke!=" ") { addJoke(new_joke); } } }); } I don't know why addJoke() function is getting executed even I don't enter any text in EditText field. Please help.

  • how to print not mapped value

    - by IcanMakeIt
    I am using complicated SQL queries, i have to use SqlQuery ... in simple way: MODEL: public class C { public int ID { get; set; } [NotMapped] public float Value { get; set; } } CONTROLLER: IEnumerable<C> results = db.C.SqlQuery(@"SELECT ID, ATAN(-45.01) as Value from C); return View(results.ToList()); VIEW: @model IEnumerable<C> @foreach (var item in Model) { @Html.DisplayFor(modelItem => item.Value) } and the result for item.Value is NULL. So my question is , how can i print the computed value from SQL Query ? Thank you for help.

  • Drupal Views: Render Null Result for Relationship as 0

    - by Kyle S
    I have a View configured in Drupal to return nodes, sorting them by their average vote in descending order. For the purpose of the View, the value of the average votes is a Relationship. I noticed that nodes with no votes are displayed after nodes with a negative average. Nodes with no votes should have an average of 0, but I believe the MySQL JOIN is causing NULL values to be returned (as there are no matching rows in the joined table, since a row is created after the first vote is cast for that item). I discovered that with MySQL it is possible to output all values that are NULL in a column as another value with IFNULL(column_name,'other value'). I feel like I would need to modify the Views module in order to obtain this functionality, but I'm hoping that there is some sort of option that returns NULL values in a relation (a relation doesn't exist for the item) as 0 instead of NULL, so that I can properly sort the nodes. The modules I am using include Views, Voting API, Vote Up/Down, and CTools. Thanks.

  • ListView GridView and Grid

    - by urema
    Hi, If you have a ListView with its view set as a GridView, which itself contains columns for each month say.....how do I set a template up for the ItemTemplate of the ListView so that each Item will be three rows high, and be inline with the ListView.View's columns? For example different employee recruits over a year.... each month across the top and each employee on the left side, though sub-columned on the employee are three rows "Name", "Address" and "Job Type" say. I know you have to use the IsSharedSizeScope attached property. January February ... Employee1 Name E1 Address E1 Street Job Type Cleaner Employee2 Name ... Address ... Job Type ... Thanks greatly in advance, U.

  • Counting multiple rows in MySQL in one query

    - by diggersworld
    I currently have a table which stores a load of statistics such as views, downloads, purchases etc. for a multiple number of items. To get a single operation count on each item I can use the following query: SELECT , COUNT() FROM stats WHERE operation = 'view' GROUP BY item_id This gives me all the items and a count of their views. I can then change 'view' to 'purchase' or 'download' for the other variables. However this means three separate calls to the database. Is it possible to get all three in one go?

  • Why does my UI controls work on iPhone but not iPad?

    - by Andrew
    I have an iPhone app, which consists of a table view containing various custom UITableViewCells, with UISlider and UISwitch controls. When running the app on the iphone, I can move the slider and switches contained in each of the table cells. When I run the same app on the iPad. I can not. None of the controls within the table view will respond to touches. I have checked 'User Interaction Enabled' within the Interface Builder. Anybody got any suggestions of where I should be looking for the cause of different behavior between the iPhone and iPad, in respect to UIControls.

  • How to Pass complex objects in ASP.NET MVC using Get parameters?

    - by VJ
    I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?

  • MATLAB: How do I get 3D coordiantes from a user-click?

    - by Tim
    I'm using Matlab to create a small chess game for one of my courses this semester. The thing I'm having trouble with is having the user be able to select one of the chess pieces. To simplify things, I'm making it so that the user selects a piece by clicking on the square that the chess piece resides on rather than clicking the piece itself (which I assume would be much more difficult). I know how to get the x and y coordinates of the view-port, but how do I transform these coordinates into 3-space coordinates? I know that there are multiple x,y,z coordinates associated with each view-port coordinate, but I'm only interested in the x,y,z coordinate where z = 0 (since the board itself is in the x,y plane that intersects the z axis where z = 0). Thanks!

  • Converting OpenGL coordinates to lower UIView (and UIImagePickerController)

    - by John Qualis
    I am new to OpenGL on the iPhone. I am developing an iPhone app similar to a barcode reader but with an extra OpenGL layer. The bottommost layer is UIImagePickerController, then I use UIView on top and draw a rectangle at certain coordinates on the iPhone screen. So far everything is OK. Then I am trying to draw an OpenGL 3-D model in that rectangle. I am able to load a 3-D model in the iPhone based on this code here - http://iphonedevelopment.blogspot.com/2008/12/start-of-wavefront-obj-file-loader.html I am not able to transform the coordinates of the rectangle into OpenGL coordinates. Appreciate any help. Do I need to use a matrix to translate the currentPosition of the 3-D model so it is drawn within myRect? The code is given below. -(void)setupView:(GLView*)view { const GLfloat zNear = 0.01, zFar = 1000.0, fieldOfView = 45.0; GLfloat size; glEnable(GL_DEPTH_TEST); glMatrixMode(GL_PROJECTION); size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); CGRect rect = view.bounds; glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glViewport(0, 0, rect.size.width, rect.size.height); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClearColor(0.0f, 0.0f, 0.0f, 0.0f); NSString *path = [[NSBundle mainBundle] pathForResource:@"plane" ofType:@"obj"]; OpenGLWaveFrontObject *theObject = [[OpenGLWaveFrontObject alloc] initWithPath:path]; Vertex3D position; position.z = -8.0; position.y = 3.0; position.x = 2.0; theObject.currentPosition = position; self.plane = theObject; [theObject release]; } - (void)drawView:(GLView*)view; { static GLfloat rotation = 0.0; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glColor4f(0.0, 0.5, 1.0, 1.0); // the coordinates of the rectangle are // myRect.x, myRect.y, myRect.width, myRect.height // Do I need to use a matrix to translate the currentPosition of the // 3-D model so it is drawn within myRect? //glOrthof(-160.0f, 160.0f, -240.0f, 240.0f, -1.0f, 1.0f); [plane drawSelf]; }

  • C++ code visualization

    - by bobobobo
    A sort of follow up/related question to this. I'm trying to get a grip on a large code base that has hundreds and hundreds of classes and a large inheritance hierarchy. I want to be able to see the "main veins" of the inheritance hierarchy at a glance - not all the "peripheral" classes that only do some very specific / specialized thing. Visual Studio's "View Class Diagram" makes something that looks like a train and its sprawled horizontally across the screen and isn't very organized. You can't grok it easily. I've just tried doxygen and graphviz but the results are .. somewhat similar to Visual Studio. I'm getting sweet looking call graphs but again too much detail for what I'm trying to get. I need a quick way to generate the inheritance hierarchy, in some kind of collapsible view.

  • Control ( UIButton, UILable) Hides when the Video plays Again on iPhone!

    - by Taimur Hamza
    Hi, I have displayed UIButton on top of Playing Movie using this code. NSArray *windows = [[UIApplication sharedApplication] windows]; if ([windows count] 1) { // Locate the movie player window UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Add our overlay view to the movie player's subviews so it is // displayed above it. [moviePlayerWindow addSubview:self.myABC]; } There are 2 buttons on top of my movie layer. They play different videos.Now the strange part is the video plays fine with buttons showing on top of it. When i press the button to play the other movie plays but the buttons doesnt show. Seems the view reloads and flushes all the Subviews. But i have checked it in the debug mode and it enters into the 'if' condition and this line runs [moviePlayerWindow addSubview:self.myABC]; But the buttons are not dislpayed. Any ideas wats going wrong ? Thanks, Taimur

  • Page layout breaks only in Opera which is weird?

    - by Qwibble
    Okay so I'm working on an admin panel, in which everything should always be only within the view port until you hit the minimum widths and heights set. The current version of it can be seen here (its still in development) : http://qwibbledesigns.co.uk/preview/Admin/ In layout terms, it works flawlessly in all browsers, even down to ie6 =D. However, opera doesn't like it, and for some reason, always add's extra space to the bottom of the page, making it have an extra scrollbar, and I can't fathom it out which is highly annoying. Jquery is used to set the height of the container, sidebar, and content area so that they're always within the browser view port, and these functions rerun when the window is resized. I therefore cannot work out the the life of me what's wrong with opera. Would anyone mind taking a look and seeing if they can work it out? =D

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

  • Problem when exiting search in iPhone

    - by camilo
    Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

  • Ajax request. Which callback is executed first complete or success?

    - by Gutzofter
    I could spike this to find out, but I'm going to use SO. In my unit tests (qunit) I use the asynchShould (alias for asynchTest) test. Part of the assertion is to wait for the completion/success of the request. Like this: asyncShould('talk to customer list server', 1, function() { stop(2000); var forCustomerList = newCustomerListRequest(); forCustomerList.page = 'helpers/helper.php'; forCustomerList.data += '&action=customerListServer&DB=11001'; var originalSuccess = forCustomerList.success; forCustomerList.success = function(msg) { if (msg.flash !== undefined && msg.data !== undefined && msg.status !== undefined) { ok(true, 'json structure correct') } else { ok(false, 'json structure not correct'); } originalSuccess(msg); start(); }; testController.getServerData(forCustomerList); })

  • How can data not stored in a DB be accessed from any activity in Android?

    - by jul
    hi, I'm passing data to a ListView to display some restaurant names. Now when clicking on an item I'd like to start another activity to display more restaurant data. I'm not sure about how to do it. Shall I pass all the restaurant data in a bundle through the intent object? Or shall I just pass the restaurant id and get the data in the other activity? In that case, how can I access my restaurantList from the other activity? In any case, how can I get data from the restaurant I clicked on (the view only contains the name)? Any help, pointers welcome! Thanks Jul ListView lv= (ListView)findViewById(R.id.listview); lv.setAdapter( new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,restaurantList.getRestaurantNames())); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent i = new Intent(Atable.this, RestaurantEdit.class); Bundle b = new Bundle(); //b.putInt("id", ? ); startActivityForResult(i, ACTIVITY_EDIT); } }); RestaurantList.java package org.digitalfarm.atable; import java.util.ArrayList; import java.util.List; public class RestaurantList { private List<Restaurant> restaurants = new ArrayList<Restaurant>(); public List<Restaurant> getRestaurants() { return this.restaurants; } public void setRestaurants(List<Restaurant> restaurants) { this.restaurants = restaurants; } public List<String> getRestaurantNames() { List<String> restaurantNames = new ArrayList<String>(); for (int i=0; i<this.restaurants.size(); i++) { restaurantNames.add(this.restaurants.get(i).getName()); } return restaurantNames; } } Restaurant.java package org.digitalfarm.atable; public class Restaurant { private int id; private String name; private float latitude; private float longitude; public int getId() { return this.id; } public void setId(int id) { this.id = id; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } public float getLatitude() { return this.latitude; } public void setLatitude(float latitude) { this.latitude = latitude; } public float getLongitude() { return this.longitude; } public void setLongitude(float longitude) { this.longitude = longitude; } }

  • How do I turn a PDF email attachment to an image (jpg) in a PHP page?

    - by user351630
    Hi guys. Long time viewer, first time question asker. I'm trying to have my personal website parse through my mail box for attachments from a certain subscription list, and then be able to view the PDF attachments as images, preferably jpg. With the help of this: http://www.linuxscope.net/articles/mailAttachmentsPHP.html I'm currently using imap_base64() to decode the MIME data and create the PDF. However, I hate using PDF readers in general and I thought it would be a lot more streamlined if I could just view it as an image instead. I've heard for convert with ImageMagick, but would I need to actually write the PDF to a directory before using this, or can I convert somehow directly from the MIME data in the email? Thanks in advanced!
