• Tips to Make Your Website Cell Phone Friendly

  - by Aditi

  Working on a new website design? or Redesigning your website? There is a lot more to consider now a days not just user experience, clean code, CSS etc. one of the important attribute one must not miss, which is making them mobile friendly! With the growing use of handhelds & unlimited data plans, people browse on their cellphones! and All come in different sizes! it is tough to make a website that would look great not just on a high resolution widescreen monitor/LCD, but also should look equally impressive on the low resolutions of cellphones. We are today going to discuss about such factors that can help you make a website Cellphone Friendly. Fluid Width Layouts As we start discussing about this, Most people speak of the Fluid Width Layouts as vital step in moving your website to be mobile friendly. Fluid width allows the width of your website stretch or shrink depending on the browser size. However, having a layout which flows with the width of the screen’s resolution is certainly convenient, more often than not the website was originally laid out for a desktop in mind. Compressing a fluid layout to 320 pixels can do some serious damage to layout, Thus some people strongly believe it is far better to have a mobile style sheet and lay out the content specifically for that screen and have more control on the display. The best thing to do is to detect the type of platform that is connected to your website and disabling or changing some tools and effects to make it look better if not perfect. Keep Your Web Pages Short length One must avoid long pages on their website, a lot of scroll makes it very non user friendly for people, especially on mobile devices this is a huge draw back because of the longer load time it takes to download the webpage. Everyone likes crisp & concise content such pages are easier to load & browse. This makes your website accessible across all platforms. Also try to keep shorter urls, if they have to type..save them from that much work especially if someone is using a cellphone with no QWERTY keyboard it can be tough. Usable Navigation & Search Unlike Desktops, your website’s Navigation won’t super work on a cellphone. Keep in mind the user experience for cellphone users as you design your Navigation. Try to keep your content centered as they do have difficulty in reading the webpage. I always look upto Google and their pages as available on mobile as a great example. Keeping a functional & very visible search bar helps mobile users navigate by searching. Understanding Clean Website Code : Evolved for Mobile Clean code is important when you consider the diversity out there for handheld devices. Some cell phones may only understand WAP. More capable phones may understand WAP2, which allows rendering websites with XHTML and CSS. Most mobiles won’t display tables, floats, frames, JavaScript, and dynamic menus. Most cellphone will not support cookies. Devices at the high end of the mobile market such as BlackBerry, Palm, or the upcoming iPhone are highly capable and support nearly as much as a standard computer..but masses still do not have such phones. You can use specific emulators to test your website on mobile devices. Make sure your color combinations provide good contrast between foreground and background colors, particularly for devices with fewer color options.

• Android - passing data between Activities

  - by Bill Osuch

  (To follow along with this, you should understand the basics of starting new activities: Link ) The easiest way to pass data from one activity to another is to create your own custom bundle and pass it to your new class. First, create two new activities called Search and SearchResults (make sure you add the second one you create to the AndroidManifest.xml file!), and create xml layout files for each. Search's file should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="Name:"/>     <EditText                android:id="@+id/edittext"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="ID Number:"/>     <EditText                android:id="@+id/edittext2"                android:layout_width="fill_parent"                android:layout_height="wrap_content"/>     <Button           android:id="@+id/btnSearch"          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="Search" /> </LinearLayout> and SearchResult's should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:id="@+id/txtName"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:id="@+id/txtState"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="No data"/> </LinearLayout> Next, we'll override the OnCreate method of Search: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search);     Button search = (Button) findViewById(R.id.btnSearch);     search.setOnClickListener(new View.OnClickListener() {         public void onClick(View view) {                           Intent intent = new Intent(Search.this, SearchResults.class);              Bundle b = new Bundle();                           EditText txt1 = (EditText) findViewById(R.id.edittext);             EditText txt2 = (EditText) findViewById(R.id.edittext2);                                      b.putString("name", txt1.getText().toString());             b.putInt("state", Integer.parseInt(txt2.getText().toString()));                              //Add the set of extended data to the intent and start it             intent.putExtras(b);             startActivity(intent);          }     }); } This is very similar to the previous example, except here we're creating our own bundle, adding some key/value pairs to it, and adding it to the intent. Now, to retrieve the data, we just need to grab the Bundle that was passed to the new Activity and extract our values from it: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search_results);     Bundle b = getIntent().getExtras();     int value = b.getInt("state", 0);     String name = b.getString("name");             TextView vw1 = (TextView) findViewById(R.id.txtName);     TextView vw2 = (TextView) findViewById(R.id.txtState);             vw1.setText("Name: " + name);     vw2.setText("State: " + String.valueOf(value)); }

• How do I use setFilmSize in panda3d to achieve the correct view?

  - by lhk

  I'm working with Panda3d and recently switched my game to isometric rendering. I moved the virtual camera accordingly and set an orthographic lens. Then I implemented the classes "Map" and "Canvas". A canvas is a dynamically generated mesh: a flat quad. I'm using it to render the ingame graphics. Since the game itself is still set in a 3d coordinate system I'm planning to rely on these canvases to draw sprites. I could have named this class "Tile" but as I'd like to use it for non-tile sketches (enemies, environment) as well I thought canvas would describe it's function better. Map does exactly what it's name suggests. Its constructor receives the number of rows and columns and then creates a standard isometric map. It uses the canvas class for tiles. I'm planning to write a map importer that reads a file to create maps on the fly. Here's the canvas implementation: class Canvas: def __init__(self, texture, vertical=False, width=1,height=1): # create the mesh format=GeomVertexFormat.getV3t2() format = GeomVertexFormat.registerFormat(format) vdata=GeomVertexData("node-vertices", format, Geom.UHStatic) vertex = GeomVertexWriter(vdata, 'vertex') texcoord = GeomVertexWriter(vdata, 'texcoord') # add the vertices for a flat quad vertex.addData3f(1, 0, 0) texcoord.addData2f(1, 0) vertex.addData3f(1, 1, 0) texcoord.addData2f(1, 1) vertex.addData3f(0, 1, 0) texcoord.addData2f(0, 1) vertex.addData3f(0, 0, 0) texcoord.addData2f(0, 0) prim = GeomTriangles(Geom.UHStatic) prim.addVertices(0, 1, 2) prim.addVertices(2, 3, 0) self.geom = Geom(vdata) self.geom.addPrimitive(prim) self.node = GeomNode('node') self.node.addGeom(self.geom) # this is the handle for the canvas self.nodePath=NodePath(self.node) self.nodePath.setSx(width) self.nodePath.setSy(height) if vertical: self.nodePath.setP(90) # the most important part: "Drawing" the image self.texture=loader.loadTexture(""+texture+".png") self.nodePath.setTexture(self.texture) Now the code for the Map class class Map: def __init__(self,rows,columns,size): self.grid=[] for i in range(rows): self.grid.append([]) for j in range(columns): # create a canvas for the tile. For testing the texture is preset tile=Canvas(texture="../assets/textures/flat_concrete",width=size,height=size) x=(i-1)*size y=(j-1)*size # set the tile up for rendering tile.nodePath.reparentTo(render) tile.nodePath.setX(x) tile.nodePath.setY(y) # and store it for later access self.grid[i].append(tile) And finally the usage def loadMap(self): self.map=Map(10, 10, 1) this function is called within the constructor of the World class. The instantiation of world is the entry point to the execution. The code is pretty straightforward and runs good. Sadly the output is not as expected: Please note: The problem is not the white rectangle, it's my player object. The problem is that although the map should have equal width and height it's stretched weirdly. With orthographic rendering I expected the map to be a perfect square. What did I do wrong ? UPDATE: I've changed the viewport. This is how I set up the orthographic camera: lens = OrthographicLens() lens.setFilmSize(40, 20) base.cam.node().setLens(lens) You can change the "aspect" by modifying the parameters of setFilmSize. I don't know exactly how they are related to window size and screen resolution but after testing a little the values above seem to work for me. Now everything is rendered correctly as long as I don't resize the window. Every change of the window's size as well as switching to fullscreen destroys the correct rendering. I know that implementing a listener for resize events is not in the scope of this question. However I wonder why I need to make the Film's height two times bigger than its width. My window is quadratic ! Can you tell me how to find out correct setting for the FilmSize ? UPDATE 2: I can imagine that it's hard to envision the behaviour of the game. At first glance the obvious solution is to pass the window's width and height in pixels to setFilmSize. There are two problems with that approach. The parameters for setFilmSize are ingame units. You'll get a way to big view if you pass the pixel size For some strange reason the image is distorted if you pass equal values for width and height. Here's the output for setFilmSize(800,800) You'll have to stress your eyes but you'll see what I mean

• Memory is full with vertex buffer

  - by Christian Frantz

  I'm having a pretty strange problem that I didn't think I'd run into. I was able to store a 50x50 grid in one vertex buffer finally, in hopes of better performance. Before I had each cube have an individual vertex buffer and with 4 50x50 grids, this slowed down my game tremendously. But it still ran. With 4 50x50 grids with my new code, that's only 4 vertex buffers. With the 4 vertex buffers, I get a memory error. When I load the game with 1 grid, it takes forever to load and with my previous version, it started up right away. So I don't know if I'm storing chunks wrong or what but it stumped me -.- for (int x = 0; x < 50; x++) { for (int z = 0; z < 50; z++) { for (int y = 0; y <= map[x, z]; y++) { SetUpVertices(); SetUpIndices(); cubes.Add(new Cube(device, new Vector3(x, map[x, z] - y, z), grass)); } } } vertexBuffer = new VertexBuffer(device, typeof(VertexPositionTexture), vertices.Count(), BufferUsage.WriteOnly); vertexBuffer.SetData<VertexPositionTexture>(vertices.ToArray()); indexBuffer = new IndexBuffer(device, typeof(short), indices.Count(), BufferUsage.WriteOnly); indexBuffer.SetData(indices.ToArray()); Thats how theyre stored. The array I'm reading from is a byte array which defines the coordinates of my map. Now with my old version, I used the same loading from an array so that hasn't changed. The only difference is the one vertex buffer instead of 2500 for a 50x50 grid. cubes is just a normal list that holds all my cubes for the vertex buffer. Another thing that just came to mind would be my draw calls. If I'm setting an effect for each cube in my cube list, that's probably going to take a lot of memory. How can I avoid doing this? I need the foreach method to set my cubes to the right position foreach (Cube block in cube.cubes) { effect.VertexColorEnabled = false; effect.TextureEnabled = true; Matrix center = Matrix.CreateTranslation(new Vector3(-0.5f, -0.5f, -0.5f)); Matrix scale = Matrix.CreateScale(1f); Matrix translate = Matrix.CreateTranslation(block.cubePosition); effect.World = center * scale * translate; effect.View = cam.view; effect.Projection = cam.proj; effect.FogEnabled = false; effect.FogColor = Color.CornflowerBlue.ToVector3(); effect.FogStart = 1.0f; effect.FogEnd = 50.0f; cube.Draw(effect); noc++; }

• Android AlertDialog with rounded corners: rectangle seen below corners

  - by user1455909

  I want a Dialog with rounded corners, but when the Dialog is seen there's a rectangle below it that's seen below the corners, like this: I build the dialog using a custom DialogFragment: public class MyDialogFragment extends DialogFragment{ @Override public Dialog onCreateDialog(Bundle savedInstanceState) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); LayoutInflater inflater = getActivity().getLayoutInflater(); builder.setView(inflater.inflate(R.layout.playdialog, null)); return builder.create(); } } The dialog layout (playdialog) has the following drawable as background: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <solid android:color="#AAAAAAAA" /> <stroke android:width="2dp" android:color="#FF000000" /> <corners android:radius="20dp" /> </shape> As I said, I set this drawable as background: android:background="@drawable/dialog_background" I don't want that rectangle to be seen. How can I do it?? In this post the user had the same problem. I tried to use the solution that worked for him but it didn't work for me. I modified my DialogFragment like this: public Dialog onCreateDialog(Bundle savedInstanceState) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); LayoutInflater inflater = getActivity().getLayoutInflater(); builder.setView(inflater.inflate(R.layout.playdialog, null)); Dialog d = builder.create(); d.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); return d; } The result is exactly the same. How can I remove that rectangle? Thanks!

  I am using Telerik RadGridView in my project. I want to show image in column. GridViewImageColumn col1 = new GridViewImageColumn(); col1.Width = 100; col1.DataMemberBinding = new Binding("id"); col1.Header = "PhotoByConverter"; col1.DataMemberBinding.Converter = new ThumbnailConverter(); grid.Columns.Add(col1); GridViewImageColumn col2 = new GridViewImageColumn(); col2.Width = 100; col2.DataMemberBinding = new Binding("firstName"); col2.Header = "Person name"; col2.DataMemberBinding.Converter = new ThumbnailConverter(); grid.Columns.Add(col2); Grid.ItemsSource=DataTable; First column not wokrs but second works fine. I use Converter for image shown below public class ThumbnailConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { IEnumerable<thumbNail> result = from n in thumbnails where n.personID == value.ToString() select n; if (result != null && result.First().thumbnail != null) { return result.First().thumbnail.file; } else { return null; } } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new Exception("The method or operation is not implemented."); } } I found by id thumbnail of person and set it like data for GridViewImageColumn. I checked with Debuger conveter works properly. I can't undesrtand why it doesn't work. Any ideas?

• Add an array of buttons to a GridView in an Android application

  - by Tai Squared

  I have an application that will have 5-15 buttons depending on what is available from a backend. How do I define the proper GridView layout files to include an array of buttons that will each have different text and other attributes? Each button will essentially add an item to a cart, so the onClick code will be the same except for the item it adds to the cart. How can I define an array so I can add a variable number of buttons, but still reference each of them by a unique ID? I've seen examples of the arrays.xml, but they have created an array of strings that are pre-set. I need a way to create an object and not have the text defined in the layout or arrays xml file. Update - Added info about adding to a GridView I want to add this to a GridView, so calling the addView method results in an UnsupportedOperationException. I can do the following: ImageButton b2 = new ImageButton(getApplicationContext()); b2.setBackgroundResource(R.drawable.img_3); android.widget.LinearLayout container = (android.widget.LinearLayout) findViewById(R.id.lay); container.addView(b2); but that doesn't layout the buttons in a grid like I would like. Can this be done in a GridView?

• CSS window height problem with dynamic loaded css

  - by Michael Mao

  Hi all: Please go here and use username "admin" and password "endlesscomic" (without wrapper quotes) to see the web app demo. Basically what I am trying to do is to incrementally integrate my work to this web app, say, every nightly, for the client to check the progress. Also, he would like to see, at the very beginning, a mockup about the page layout. I am trying to use the 960 grid system to achieve this. So far, so good. Except one issue that when the "mockup.css" is loaded dynamically by jQuery, it "extends" the window to the bottom, something I do not wanna have... As an inexperienced web developer, I don't know which part is wrong. Below is my js: /* master.js */ $(document).ready(function() { $('#addDebugCss').click(function() { alertMessage('adding debug css...'); addCssToHead('./css/debug.css'); $('.grid-insider').css('opacity','0.5');//reset mockup background transparcy }); $('#addMockupCss').click(function() { alertMessage('adding mockup css...'); addCssToHead('./css/mockup.css'); $('.grid-insider').css('opacity','1');//set semi-background transparcy for mockup }); $('#resetCss').click(function() { alertMessage('rolling back to normal'); rollbackCss(new Array("./css/mockup.css", "./css/debug.css")); }); }); function alertMessage(msg) //TODO find a better modal prompt { alert(msg); } function addCssToHead(path_to_css) { $('<link rel="stylesheet" type="text/css" href="' + path_to_css + '" />').appendTo("head"); } function rollbackCss(set) { for(var i in set) { $('link[href="'+ set[i]+ '"]').remove(); } } Something should be added to the exteral mockup.css? Or something to change in my master.js? Thanks for any hints/suggestions in advance.

• ExtJS: Combobox in EditorGridPanel not selecting the desired item (with test case)

  - by TomH

  I'm using ExtJS to create an EditorGridPanel with a combobox for an editor in a cell. The combobox in my EditorGridPanel that is not working as I'd expect it to. When the user types the first letter of an item in the drop down list, the combobox seems to ignore it and select the first item in the list. I can reproduce the error consistently and have put together a test case here: http://cluebucket.com/dev/testcase/testcase.html Load the page and reproduce the behavior by the following -- note that this is all done using the keyboard, no mouse clicks: Click 'Add Record' (A new row is added to the grid) enter text in the text field. TAB to the Priority field without selecting anything (None will remain selected) TAB out of the Priority field. (A new row is added to the grid) enter text and TAB to the Priority field TYPE v (Very High is selected) TAB out of the priority field (A new row is added to the grid) enter text and TAB to the Priority field Type v (None is selected, but Very High should have been) TAB out of the priority field Enter text and TAB to the priority field Type l ('el') (Low is selected) TAB out, enter text, TAB to priority Type l (None is selected) It appears that whenever the user attempts to select the same value that was selected in the previous row, the combobox selects None. Any ideas? The code is available at cluebucket.com/dev/testcase/js/testcase.js Thoughts/Pointers/Corrections are appreciated!! thanks tom

• Jqgrid: navigation based on the selected row

  - by bsreekanth

  Hello, I was trying to enable navigation based on a selected row. So, the user select a row from jQgrid, and when press the show (is there a show button for the grid, I saw edit, add etc), it needs to go to a new page based on the url (part of the row). $(document).ready(function () { function getLink() { // var rowid = $("#customer_list").jqGrid('getGridParam', 'selrow'); var rowid = $("#customer_list").getGridParam('selrow'); var MyCellData = $("#customer_list").jqGrid('getCell', rowid, 'dataUrl'); return MyCellData; } $("#customer_list").jqGrid({ url:'mytestList', editurl:'jq_edit_test', datatype: "json", colNames:['Call Id','Title','dataUrl'], colModel:[ {name:'callId', width:80, search:false }, {name:'title', width:200, sortable:false }, {name:'dataUrl',hidden:true} ], rowNum:10, sortname:'lastUpdated', sortorder: 'desc', pager:'#customer_list_pager', viewrecords: true, gridview: true }).navGrid('#customer_list_pager', {add:true,edit:true,del:false,search:true,refresh:true}, {closeAfterEdit:true, afterSubmit:afterSubmitEvent }, // edit options {addCaption:'Create New something', afterSubmit:afterSubmitEvent, savekey:[true,13]}, // add options {afterSubmit:afterSubmitEvent} // delete options ); $("#customer_list").jqGrid('filterToolbar'); }); so, the url is passed for each row as dataUrl. I'm trying to read it and set to the button. Whn debug through firebug, the rowid was 223 (there were only 12 rows in the grid), and the cell value is empty. Currently the button is kept outside the grid, but it may better to be it part of the vavGrid thanks.

• How to do server-side validation using Jqgrid?

  - by Eoghan

  Hi, I'm using jqgrid to display a list of sites and I want to do some server side validation when a site is added or edited. (Form editing rather than inline. Validation needs to be server side for various reasons I won't go into.) I thought the best way would be to check the data via an ajax request when the beforeSubmit event is triggered. However this only seems to work when I'm editing an existing row in the grid - the function isn't called when I add a new row. Have I got my beforeSubmit in the wrong place? Thanks for your help. $("#sites-grid").jqGrid({ url:'/json/sites', datatype: "json", mtype: 'GET', colNames:['Code', 'Name', 'Area', 'Cluster', 'Date Live', 'Status', 'Lat', 'Lng'], colModel :[ {name:'code', index:'code', width:80, align:'left', editable:true}, {name:'name', index:'name', width:250, align:'left', editrules:{required:true}, editable:true}, {name:'area', index:'area', width:60, align:'left', editable:true}, {name:'cluster_id', index:'cluster_id', width:80, align:'right', editrules:{required:true, integer:true}, editable:true, edittype:"select", editoptions:{value:"<?php echo $cluster_options; ?>"}}, {name:'estimated_live_date', index:'estimated_live_date', width:120, align:'left', editable:true, editrules:{required:true}, edittype:"select", editoptions:{value:"<?php echo $this->month_options; ?>"}}, {name:'status', index:'status', width:80, align:'left', editable:true, edittype:"select", editoptions:{value:"Live:Live;Plan:Plan;"}}, {name:'lat', index:'lat', width:140, align:'right', editrules:{required:true}, editable:true}, {name:'lng', index:'lng', width:140, align:'right', editrules:{required:true}, editable:true}, ], height: '300', pager: '#pager-sites', rowNum:30, rowList:[10,30,90], sortname: 'cluster_id', sortorder: 'desc', viewrecords: true, multiselect: false, caption: 'Sites', editurl: '/json/sites' }); $("#sites-grid").jqGrid('navGrid','#pager-sites',{edit:true,add:true,del:true, beforeSubmit : function(postdata, formid) { $.ajax({ url : 'json/validate-site/', data : postdata, dataType : 'json', type : 'post', success : function(data) { alert(data.message); return[data.result, data.message]; } }); }});

• Resource not found using library project in Android

  - by hgpc

  I'm converting an existing project into a library project. I configured the original project as a library project and added an application project which references the original project as a library. The library project has an activity (MainActivity) and its layout (main.xml). The application project declares this activity as the main activity in the manifest like this: <activity android:name="com.example.MainActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> When I run the application project I get the following error... android.content.res.Resources$NotFoundException: Resource ID #0x7f030002 ...on the following line of the onCreate method of the main activity: setContentView(R.layout.main); 0x7f030002 is the ID of R.layout.main in the library project. The application project has no main resource. If I run the original project I don't get this error. Both projects neither have compilation errors nor warnings and are built with Android 2.2 with min SDK version 3. What might be the problem?

• WPF Ignoring ProgressBar Style

  - by Nidonocu

  Following a problem in WPF 4 where the default ProgressBar template has an off-white highlight applied causing it to dull the foreground colour, I decided to extract the template and manually edit the values to white. After doing this, I put the template as a style in App.xaml for global use and the Visual Studio designer began to use it right away. However, when I run my app, the default style is still being applied: I then tried setting the style specifically using a key, then even having it as an inline style and finally as a inline template without a wrapping style for the specific progress bar and it is still ignored. What's going wrong? Current Code for progress bar: <ProgressBar Grid.Column="1" Grid.Row="2" Height="15" Width="355" Margin="0,0,0,7" IsIndeterminate="{Binding ProgressState, FallbackValue=False}" Visibility="{Binding ProgressVisibility, FallbackValue=Collapsed}" Value="{Binding ProgressValue, Mode=OneWay, FallbackValue=100}" Foreground="{Binding ProgressColor,FallbackValue=Red}"> <ProgressBar.Template> <ControlTemplate> <Grid Name="TemplateRoot" SnapsToDevicePixels="True"> <Rectangle RadiusX="2" RadiusY="2" Fill="{TemplateBinding Panel.Background}" /> ...

• Android - Images from Assets folder in a GridView

  - by Saran

  Hi, I have been working on creating a Grid View of images, with images being present in the Assets folder. http://stackoverflow.com/questions/1933015/opening-an-image-file-inside-the-assets-folder link helped me with using the bitmap to read it. The code am currently having is: public View getView(final int position, View convertView, ViewGroup parent) { try { AssetManager am = mContext.getAssets(); String list[] = am.list(""); int count_files = imagelist.length; for(int i= 0;i<=count_files; i++) { BufferedInputStream buf = new BufferedInputStream(am.open(list[i])); Bitmap bitmap = BitmapFactory.decodeStream(buf); imageView.setImageBitmap(bitmap); buf.close(); } } catch (IOException e) { e.printStackTrace(); } } My application does read the image from the Assets folder, but it is not iterating through the cells in the grid view. All the cells of the grid view have a same image picked from the set of images. Can anyone tell me how to iterate through the cells and still have different images ? I have the above code in an ImageAdapter Class which extends the BaseAdapter class, and in my main class I am linking that with my gridview by: GridView gv =(GridView)findViewById(R.id.gridview); gv.setAdapter(new ImageAdapter(this, assetlist)); Thanks a lot for any help in advance, Saran

• NHibernate, Databinding to DataGridView, Lazy Loading, and Session managment - need advice

  - by Tom Bushell

  My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running. For performance reasons, I set the convention DefaultLazy.Always() for all DB access. So far, the only way I've found to make this work is to keep a Session (let's call it MainSession) open all the time for the main form, so NHibernate can lazy load new data as the user navigates with the grid. Another part of the application can run in the background, and Save to the DB. Currently, (after considerable struggle), my approach is to call MainSession.Disconnect(), create a disposable Session for each Save, and MainSession.Reconnect() after finishing the Save. Otherwise SQLite will throw "The database file is locked" exceptions. This seems to be working well so far, but past experience has made me nervous about keeping a session open for a long time (I ran into performance problems when I tried to use a single session for both Saves and Loads - the cache filled up, and bogged down everything - see http://stackoverflow.com/questions/2526675/commit-is-very-slow-in-my-nhibernate-sqlite-project). So, my question - is this a good approach, or am I looking at problems down the road? If it's a bad approach, what are the alternatives? I've considered opening and closing my main session whenever the user navigates with the grid, but it's not obvious to me how I would do that - hook every event from the grid that could possibly cause a lazy load? I have the nagging feeling that trying to manage my own sessions this way is fundamentally the wrong approach, but it's not obvious what the right one is.

• how to read user input from custom dialog in android?

  - by urobo

  I'd like to use a custom dialog built over an AlterDialog to obtain login info from the user. In this manner I first use the layoutinflater to get the layout and then put it in the AlertDialog.Builder.setView() method. LayoutInflater inflater = (LayoutInflater) Home.this.getSystemService(LAYOUT_INFLATER_SERVICE); layoutLogin = inflater.inflate(R.layout.login,(ViewGroup) findViewById(R.id.rl)); My layout consists of two textview and two editext for username and password respectively. Then I override the onCreateDialog method, checking the dialog id and putting all together, during the building phase I use the setButton(...) method to add a confirmation Button, neutral though: /* (non-Javadoc) * @see android.app.Activity#onCreateDialog(int) */ @Override protected Dialog onCreateDialog(int id) { AlertDialog d = null; AlertDialog.Builder builder = new AlertDialog.Builder(this); switch(id){ ... case Home.DIALOG_LOGIN: builder.setView(layoutLogin); builder.setMessage("Sign in to your DyCaPo Account").setCancelable(false); d=builder.create(); d.setTitle("Login"); Message msg = new Message(); msg.setTarget(Home.this.handleLogin); d.setButton(Dialog.BUTTON_NEUTRAL,"Sign in",msg); break; ... } return d; } Then I setup the Handler handleLogin: private Handler handleLogin= new Handler(){ /* (non-Javadoc) * @see android.os.Handler#handleMessage(android.os.Message) */ @Override public void handleMessage(Message msg) { String input = usernameInput.getText().toString(); //this should hold the EditText field for the username } }; which is just a stub up to now. what I don't get is when and where I have to access the two fields since I tried to save a reference to them but unfortunately I always get a null pointer exception. Can anyone tell me what I do wrong and give some guidelines to work with custom dialogs. Thanks in advance! :)

• Android: How to keep onItemSelected from firing off on a newly instantiated Spinner

  - by Drennen

  I've thought of some less than elegant ways to solve this, but I know I must be missing something. My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything. I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control? THANKS public class CMSHome extends Activity { private Spinner spinner; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Heres my spinner /////////////////////////////////////////// spinner = (Spinner) findViewById(R.id.spinner); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.pm_list, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); }; public void onResume() { super.onResume(); spinner.setOnItemSelectedListener(new MyOnItemSelectedListener()); } public class MyOnItemSelectedListener implements OnItemSelectedListener { public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { Intent i = new Intent(CMSHome.this, ListProjects.class); i.putExtra("bEmpID", parent.getItemAtPosition(pos).toString()); startActivity(i); Toast.makeText(parent.getContext(), "The pm is " + parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show(); } public void onNothingSelected(AdapterView parent) { // Do nothing. } } }

• OAuthWebSecurity.VerifyAuthentication IsSuccessful returns false how do I to determine the reason?

  - by Eonasdan

  I'm using DotNetOpenAuth with a MVC 4 application. All the sudden Google auth is failing (MS is working). The stock code does this: [AllowAnonymous] public ActionResult ExternalLoginCallback(string returnUrl) { var result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl })); if (!result.IsSuccessful) { return RedirectToAction("ExternalLoginFailure"); } I know that result.IsSuccessful is false, but how do I get the reason? result.Error is null. I also looked at this page to use log4net. I do get a log on the local dev box but not when I deploy it to a remote server. log4net webconfig: <log4net> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="RelyingParty.log" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="100KB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date (GMT%date{%z}) [%thread] %-5level %logger - %message%newline" /> </layout> </appender> <!-- Setup the root category, add the appenders and set the default level --> <root> <level value="INFO" /> <appender-ref ref="RollingFileAppender" /> </root> <!-- Specify the level for some specific categories --> <logger name="DotNetOpenAuth"> <level value="ALL" /> </logger> </log4net> Edit I also tried log4net to a sql db but it still didn't log anything

• WPF Constrain the resize of a canvas' child object to the dimensions of the canvas

  - by Scott

  Given the following XAML: <Window x:Class="AdornerTesting.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="500" Width="500" Loaded="Window_Loaded"> <Grid Name="grid"> <Canvas Name="canvas" Width="400" Height="400" Background="LightGoldenrodYellow"> <RichTextBox Name="richTextBox" Canvas.Top="10" Canvas.Left="10" BorderBrush="Black" BorderThickness="2" Width="200" Height="200" MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Canvas}},Path=ActualWidth}" MaxHeight="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Canvas}},Path=ActualHeight}"/> </Canvas> </Grid> </Window> and a set of adorners being added to the RichTextBox in the Loaded event like so: AdornerLayer adornerLayer = AdornerLayer.GetAdornerLayer(richTextBox); adornerLayer.Add(new ResizeAdorner(richTextBox)); How do I keep from being able to resize the RichTextBox beyond the visble bounds of the Canvas? The ResizeAdorner is essentially the same code that can be found in the MSDN adorner example and it works just fine. Should I be doing something with the bindings of MaxWidth and MaxHeight in the code-behind to calculate how the RichTextBox can be resized? Or is there a way to do this in XAML?

• ExtJS: Autoscroll vertical FormPanels added to panel

  - by Sarge

  Hi All, I'm writing an app where I have a BorderLayout for the entire page. In the south part I have a Panel to which I add FormPanels. I would like to be able to scroll that Panel so I can scroll through the FormPanels. So far, nothing I've found from searches has helped. I don't quite understand what ExtJS requires in terms of the combination of LayoutManagers, setting the size and setting AutoScroll. Any partial tips will be gratefully followed up. A code snippet: createTrailJunctionPanel = function(trailJunction) { var trailJunctionPanel = new Ext.form.FormPanel({ labelWidth: 75, width: 350, defaultType: 'textfield', items: [{ fieldLabel: 'Junction Name', name: 'junction-name' }], autoScroll:true, //anchor: '100% 100%', height: 100 }); matchedTrailJunctionsPanel.add(trailJunctionPanel); if(trailJunction.publicTrailSegments.length == 0) { matchedTrailJunctionsPanel.add(new Ext.form.Label({text: 'No public trails matched'})); } else { var grid = new Ext.grid.GridPanel({ store: mapMatchObjectStore, columns: [ {id:'publicTrailSegment',header: 'Trail', width: 160, sortable: true, dataIndex: 'publicTrailSegment'} ], stripeRows: true, autoExpandColumn: 'publicTrailSegment', height: 350, width: 600, title: 'Matched Trail Junctions' }); matchedTrailJunctionsPanel.add(grid); } matchedTrailJunctionsPanel.doLayout(); } matchedTrailJunctionsPanel = new Ext.Panel({ title: "Matched Trail Junctions2", id: "matched-trail-junctions", autoScroll:true //layout: 'anchor' });

• pyqt QTreeWidget setItemWidget dissapears after drag/drop

  - by mleep

  I'm trying to keep a widget put into a QTreeWidgetItem after a reparent (drag and drop) using QTreeWidget.setItemWidget() But the result, if you compile the following code - is that the widget inside the QTreeWidgetItem disappears. Any idea why? What code would fix this (repopulate the QTreeWidgetItem with the widget I guess?) from PyQt4.QtCore import * from PyQt4.QtGui import * class InlineEditor (QWidget): _MUTE = 'MUTE' def __init__ (self, parent): QWidget.__init__ (self, parent) self.setAutoFillBackground (True) lo = QHBoxLayout() lo.setSpacing(4) self._cbFoo = QComboBox() for x in ["ABC", "DEF", "GHI", "JKL"]: self._cbFoo.addItem(x) self._leBar = QLineEdit('', self) lo.addWidget (self._cbFoo, 3) lo.addSpacing (5) lo.addWidget (QLabel ( 'Bar:')) lo.addWidget (self._leBar, 3) lo.addStretch (5) self.setLayout (lo) class Form (QDialog): def __init__(self,parent=None): QDialog.__init__(self, parent) grid = QGridLayout () tree = QTreeWidget () # Here is the issue? tree.setDragDropMode(QAbstractItemView.InternalMove) tree.setColumnCount(3) for n in range (2): i = QTreeWidgetItem (tree) # create QTreeWidget the sub i i.setText (0, "first" + str (n)) # set the text of the first 0 i.setText (1, "second") for m in range (2): j = QTreeWidgetItem(i) j.setText (0, "child first" + str (m)) #b1 = QCheckBox("push me 0", tree) # this wont work w/ drag by itself either #tree.setItemWidget (tree.topLevelItem(0).child(1), 1, b1) item = InlineEditor(tree) # deal with a combination of multiple controls tree.setItemWidget(tree.topLevelItem(0).child(1), 1, item) grid.addWidget (tree) self.setLayout (grid) app = QApplication ([]) form = Form () form.show () app.exec_ ()

• Why does Graphviz fail on gvLayout?

  - by David Brown

  Once again, here I am writing C without really knowing what I'm doing... I've slapped together a simple function that I can call from a C# program that takes a DOT string, an output format, and a file name and renders a graph using Graphviz. #include "types.h" #include "graph.h" #include "gvc.h" #define FUNC_EXPORT __declspec(dllexport) // Return codes #define GVUTIL_SUCCESS 0 #define GVUTIL_ERROR_GVC 1 #define GVUTIL_ERROR_DOT 2 #define GVUTIL_ERROR_LAYOUT 3 #define GVUTIL_ERROR_RENDER 4 FUNC_EXPORT int RenderDot(char * dotData, const char * format, const char * fileName) { Agraph_t * g; // The graph GVC_t * gvc; // The Graphviz context int result; // Result of layout and render operations // Create a new graphviz context gvc = gvContext(); if (!gvc) return GVUTIL_ERROR_GVC; // Read the DOT data into the graph g = agmemread(dotData); if (!g) return GVUTIL_ERROR_DOT; // Layout the graph result = gvLayout(gvc, g, "dot"); if (result) return GVUTIL_ERROR_LAYOUT; // Render the graph result = gvRenderFilename(gvc, g, format, fileName); if (result) return GVUTIL_ERROR_RENDER; // Free the layout gvFreeLayout(gvc, g); // Close the graph agclose(g); // Free the graphviz context gvFreeContext(gvc); return GVUTIL_SUCCESS; } It compiles fine, but when I call it, I get GVUTIL_ERROR_LAYOUT. At first, I thought it might have been how I was declaring my P/Invoke signature, so I tested it from a C program instead, but it still failed in the same way. RenderDot("digraph graphname { a -> b -> c; }", "png", "C:\testgraph.png"); Did I miss something? EDIT If there's a chance it has to do with how I'm compiling the code, here's the command I'm using: cl gvutil.c /I "C:\Program Files (x86)\Graphviz2.26\include\graphviz" /LD /link /LIBPATH:"C:\Program Files (x86)\Graphviz2.26\lib\release" gvc.lib graph.lib cdt.lib pathplan.lib I've been following this tutorial that explains how to use Graphviz as a library, so I linked to the .lib files that it listed.

• jqGrid > datatype : "local" > get and save (at once) all edited cells of a column ?

  - by Qualliarys

  Hi, i have a grid with a datatype = "local". The data are an array as follows : var mydata = [{id:1,valeur:"a_value",designation:"a_designation"}, {id:2,...}, ...]; The second column (named valeur) is the only editable column of the grid (editable:true set in colModel) In the pager of the grid, i have 2 buttons. One to edit all cells (at once) of the column named valeur: $("#mygrid").jqGrid('navButtonAdd','#pager',{caption:"Edit values", onClickButton:function(){ var ids = $('#mygrid').jqGrid('getDataIDs'); for(var i=0;i<ids.length+1;i++){ $('#mygrid').jqGrid('editRow',ids[i],true);} }}); and another one to save (at once) all the changes of the edited cells: $("#mygrid").jqGrid('navButtonAdd','#pager',{caption:"Save changes", onClickButton:function(){var ids = $('#mygrid').jqGrid('getDataIDs'); for(var i=0;i<ids.length+1;i++){ ... ??? ... }}}); when i use : var rd = $("#mygrid").jqGrid('getRowData',ids[i]); alert("valeur="+rd.valeur); for each display i get something like that: valeur=< input class="editable" role="textbox" name="valeur" id="1_valeur" style="width: 98%;" type="text" ... So, when cells are in edition mode, all rd.valeur are an input text tag ! when they are not, i get the initials values of the cells ! How to get and save all changes of this column (all cells in edition mode)?

• html textfield in WebView in an Android application is hidden by the soft keyboard

  - by user280503

  Hello, I have an Android application that is a TabHost with a WebView. I use it to load a specific html file that has a text field in its bottom part. When I touch the html textfield, the soft keyboard pops up, and hides the textfield, so that I cannot see what I have typed. Here is the layout: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/main" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TabWidget android:focusableInTouchMode="false" android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="63dp" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" /> </LinearLayout> </FrameLayout> </LinearLayout> </TabHost> I have tried to configure the AndroidManifest.xml file with android:windowSoftInputMode="adjustResize" with no success. I have also tried replacing the FrameLayout in my layout with ScollView, but that caused my webview to increase in size indefinitely when the application is running.. this may be due to some javascript I have running on the page. I have noticed that the android's web browser has a nifty behaviour - in a web page, after the soft keyboard pops up, the web page scrolls smoothly so that the focusable textfield is visible to the user. How can I have this kind of behavior in my applicaiton?
