• train wreck. Rails requires RubyGems >= 1.3.2

  - by JZ

  I recently upgraded ruby to ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10] and I think I broke rails. When I attempt to load rails. I get an odd message. Please help! $ ruby script/server Rails requires RubyGems = 1.3.2.

• How to design a high-level application protocol for metadata syncing between devices and server?

  - by Jaanus

  I am looking for guidance on how to best think about designing a high-level application protocol to sync metadata between end-user devices and a server. My goal: the user can interact with the application data on any device, or on the web. The purpose of this protocol is to communicate changes made on one endpoint to other endpoints through the server, and ensure all devices maintain a consistent picture of the application data. If user makes changes on one device or on the web, the protocol will push data to the central repository, from where other devices can pull it. Some other design thoughts: I call it "metadata syncing" because the payloads will be quite small, in the form of object IDs and small metadata about those ID-s. When client endpoints retrieve new metadata over this protocol, they will fetch actual object data from an external source based on this metadata. Fetching the "real" object data is out of scope, I'm only talking about metadata syncing here. Using HTTP for transport and JSON for payload container. The question is basically about how to best design the JSON payload schema. I want this to be easy to implement and maintain on the web and across desktop and mobile devices. The best approach feels to be simple timer- or event-based HTTP request/response without any persistent channels. Also, you should not have a PhD to read it, and I want my spec to fit on 2 pages, not 200. Authentication and security are out of scope for this question: assume that the requests are secure and authenticated. The goal is eventual consistency of data on devices, it is not entirely realtime. For example, user can make changes on one device while being offline. When going online again, user would perform "sync" operation to push local changes and retrieve remote changes. Having said that, the protocol should support both of these modes of operation: Starting from scratch on a device, should be able to pull the whole metadata picture "sync as you go". When looking at the data on two devices side by side and making changes, should be easy to push those changes as short individual messages which the other device can receive near-realtime (subject to when it decides to contact server for sync). As a concrete example, you can think of Dropbox (it is not what I'm working on, but it helps to understand the model): on a range of devices, the user can manage a files and folders—move them around, create new ones, remove old ones etc. And in my context the "metadata" would be the file and folder structure, but not the actual file contents. And metadata fields would be something like file/folder name and time of modification (all devices should see the same time of modification). Another example is IMAP. I have not read the protocol, but my goals (minus actual message bodies) are the same. Feels like there are two grand approaches how this is done: transactional messages. Each change in the system is expressed as delta and endpoints communicate with those deltas. Example: DVCS changesets. REST: communicating the object graph as a whole or in part, without worrying so much about the individual atomic changes. What I would like in the answers: Is there anything important I left out above? Constraints, goals? What is some good background reading on this? (I realize this is what many computer science courses talk about at great length and detail... I am hoping to short-circuit it by looking at some crash course or nuggets.) What are some good examples of such protocols that I could model after, or even use out of box? (I mention Dropbox and IMAP above... I should probably read the IMAP RFC.)

  Exception: object references an unsaved transient instance - save the transient instance before flushing: Child How to reproduce issue: 1. Hibernate is load the entity "Parent". The property "child" is null 2. The "Parent" is rendered on the screen and after that the "child" property is auto instantiated. So I have the following graph: Parent.child != null Parent.child.childId = null Parent.child.childKey = "" Parent.child.childName = "" Question: How I could to force the Hibernate to ignore updating or inserting Child entity WHEN childId = null?

  - by w0rldart

  So I am trying to code the footer of my web app of it occupies the rest of the body's height. Picture: http://img1.uploadscreenshot.com/images/orig/3/8906151296-orig.png Notice the light area beneath the dark area, the dark area should occupy all of it. Some of my html code: <body> .... <footer> <hr> <ul id="footerContainer"> <li class="right"> <ul> <li> <a href="" class="family-filter">Filtro Fami....</a> </li> </ul> </li> </ul> </footer> <script>...</script> </body></html> CSS: .... #footerContainer {width: 90%; min-width: 525px; margin: 0 auto; position: relative;} .... footer hr{ border: 0; height: 30px; background: url('../imgs/footer-top.png') repeat-x scroll; } footer { background: url('../imgs/footer-bg.png') repeat scroll bottom; height: 100%; display: block; margin: 0 auto; padding: 0; overflow: auto; } #footerContainer {margin: 0 auto; position: relative;} #footerContainer li { display: inline;} #footerContainer li .right {float: right;} #footerContainer li a {} Any suggestions?

• Save HashMap data into SQLite

  - by Matthew

  I'm Trying to save data from Json into SQLite. For now I keep the data from Json into HashMap. I already search it, and there's said use the ContentValues. But I still don't get it how to use it. I try looking at this question save data to SQLite from json object using Hashmap in Android, but it doesn't help a lot. Is there any option that I can use to save the data from HashMap into SQLite? Here's My code. MainHellobali.java // Hashmap for ListView ArrayList<HashMap<String, String>> all_itemList; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_helloballi); all_itemList = new ArrayList<HashMap<String, String>>(); // Calling async task to get json new getAllItem().execute(); } private class getAllItem extends AsyncTask<Void, Void, Void> { @Override protected Void doInBackground(Void... arg0) { // Creating service handler class instance ServiceHandler sh = new ServiceHandler(); // Making a request to url and getting response String jsonStr = sh.makeServiceCall(url, ServiceHandler.GET); Log.d("Response: ", "> " + jsonStr); if (jsonStr != null) { try { all_item = new JSONArray(jsonStr); // looping through All Contacts for (int i = 0; i < all_item.length(); i++) { JSONObject c = all_item.getJSONObject(i); String item_id = c.getString(TAG_ITEM_ID); String category_name = c.getString(TAG_CATEGORY_NAME); String item_name = c.getString(TAG_ITEM_NAME); // tmp hashmap for single contact HashMap<String, String> allItem = new HashMap<String, String>(); // adding each child node to HashMap key => value allItem.put(TAG_ITEM_ID, item_id); allItem.put(TAG_CATEGORY_NAME, category_name); allItem.put(TAG_ITEM_NAME, item_name); // adding contact to contact list all_itemList.add(allItem); } } catch (JSONException e) { e.printStackTrace(); } } else { Log.e("ServiceHandler", "Couldn't get any data from the url"); } return null; } } I have DatabasehHandler.java and AllItem.java too. I can put it in here if its necessary. Thanks before ** Add Edited Code ** // looping through All Contacts for (int i = 0; i < all_item.length(); i++) { JSONObject c = all_item.getJSONObject(i); String item_id = c.getString(TAG_ITEM_ID); String category_name = c.getString(TAG_CATEGORY_NAME); String item_name = c.getString(TAG_ITEM_NAME); DatabaseHandler databaseHandler = new DatabaseHandler(this); //error here "The Constructor DatabaseHandler(MainHellobali.getAllItem) is undefined }

• Can't access font resource in Silverlight class library

  - by Matt

  I have a reasonably large Silveright 3.0 project on the go, and I'm having issues accessing a couple of custom font resources from within one of the assemblies. I've got a working test solution where I have added a custom font as a resource, and can access it fine from XAML using: <TextBlock Text="Test" FontFamily="FontName.ttf#Font Name" /> The test solution consists of the TestProject.Application and the TestProject.Application.Web projects, with all the fun and games obviously in the TestProject.Application project However, when I try this in my main solution, the fonts refuse to show in the correct type face (instead showing in the default font). There's no difference in the way the font has been added to project between the test solution and the main solution, and the XAML is identical. However, there is a solution layout difference. In the main solution, as well as having a MainApp.Application and MainApp.Application.Web project, I also have a MainApp.Application.ViewModel project and a MainApp.Application.Views project, and the problem piece of XAML is the in the MainApp.Application.Views project (not the .Application project like the test solution). I've tried putting the font into either the .Application or .Application.Views project, tried changing the Build Action to Content, Embedded Resource etc, all to no avail. So, is there an issue accessing font resources from a child assembly that I don't know about, or has anyone successfully done this? My long term need will be to have the valid custom fonts being stored as resources in a separate .Application.FontLibrary assembly that will be on-demand downloaded and cached, and the XAML controls in the .Application.Views project will need to reference this FontLibrary assembly to get the valid fonts. I've also tried xcreating this separate font library assembly, and I can't seem to get the fonts from the second assembly. As some additional information, I've also tried the following font referencing approaches: <TextBlock Text="Test" FontFamily="/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;component/FontName.ttf#Font Name" /> And a few similar variants with different assembly references/sub directories/random semi colons. And so far nothing works... anyone struck this (and preferably solved it)?

• PDF Report generation

  - by IniTech

  EDIT : I completed this project using ABCpdf. For anyone interested, I love this product and their support is A+. Everything I listed as a 'Con' for the HTML - PDF solution was easily doable in ABCpdf. I've been charged with creating a data driven pdf report. After reviewing the plethora of options, I have narrowed it down to 2. I need you all to to help me decide, or offer alternatives I haven't considered. Here are the requirements: 100% Data driven Eventually PDF (a stop in HTML is fine, so long as it is converted) Can be run with multiple sets of data (the layout is always the same, the data is variable) Contains normal analysis-style copy (saved in DB with html markup) Contains tables (data for tables is generated at run-time) Header/Page # on each page Table of Contents .NET (VB or C#) Done quickly Now, because of the fact that the report is going to be generated with multiple sets of data, I don't think a stamped pdf template will work since I won't know how long or how many pages a certain piece of the report could require. So, I think my best options are: Programmatic creation using an iText-like solution. Generate in HTML and convert to PDF using a third-party application (ABCPdf is the tool I have played with so far) Both solutions have their pro's and con's. Programmatic solution: Pros: Flexible Easy page numbering/page header/table of contents Free Cons: Time consuming (to write a layer on top of iText to do what I need and keep maintainable) Since the copy is already stored in the db with html markup, I would have to parse through the data before I place it into the pdf, ensuring I don't have to break the paragraph into chunks so I can apply bold, italic, underline, etc. to specific phrases. This seems like a huge PITA, and I hope I am wrong about that assumption. HTML - PDF Pros: Easy to generate from db (no parsing necessary) Many tools for conversion Uses technology I am already familiar with Built-in "Print Preview" - not a req, but nice Cons: (Edited after project completion. All of my assumptions were incorrect and ABCpdf is awesome) 1. Almost impossible to generate page headers - Not True 2. Very difficult to generate page numbers Not True 3. Nearly impossible to generate table of contents Not True 4. (Cross-browser support isn't a con; Since its internal, I can dictate what browser to use) 5. Conversion tool quirks - may not convert exactly as rendered in browser Not True 6. Overall, I think it would be very hard to format the HTML exactly as I would want it to appear/convert to PDF. Not True That's it - I need the communitys help in deciding which way I should go. I might be wrong about some of my Pro/Con assumptions. If I am, please tell me. All thoughts and suggestions are welcome and appreciated. Thanks

• Trying to filter a ListView with runQueryOnBackgroundThread but nothing happens - what am I missing?

  - by Ian Leslie

  I have a list of countries in a database. I have created a select country activity that consists of a edit box for filtering and a list which displays the flag and country name. When the activity starts the list shows the entire list of countries sorted alphabetically - works fine. When the customer starts typing into the search box I want the list to be filtered based on their typing. My database query was previously working in an AutoCompleteView (I just want to switch to a separate text box and list) so I know my full query and my constraint query are working. What I did was add a TextWatcher to the EditText view and every time the text is changed I invoke the list's SimpleCursorAdapter runQueryOnBackgroundThread with the edit boxes text as the constraint. The trouble is the list is never updated. I have set breakpoints in the debugger and the TextWatcher does make the call to runQueryOnBackgroundThread and my FilterQueryProvider is called with the expected constraint. The database query goes fine and the cursor is returned. The cursor adapter has a filter query provider set (and a view binder to display the flag): SimpleCursorAdapter adapter = new SimpleCursorAdapter (this, R.layout.country_list_row, countryCursor, from, to); adapter.setFilterQueryProvider (new CountryFilterProvider ()); adapter.setViewBinder (new FlagViewBinder ()); The FitlerQueryProvider: private final class CountryFilterProvider implements FilterQueryProvider { @Override public Cursor runQuery (CharSequence constraint) { Cursor countryCursor = myDbHelper.getCountryList (constraint); startManagingCursor (countryCursor); return countryCursor; } } And the EditText has a TextWatcher: myCountrySearchText = (EditText)findViewById (R.id.entry); myCountrySearchText.setHint (R.string.country_hint); myCountrySearchText.addTextChangedListener (new TextWatcher() { @Override public void afterTextChanged (Editable s) { SimpleCursorAdapter filterAdapter = (SimpleCursorAdapter)myCountryList.getAdapter (); filterAdapter.runQueryOnBackgroundThread (s.toString ()); } @Override public void onTextChanged (CharSequence s, int start, int before, int count) { // no work to do } @Override public void beforeTextChanged (CharSequence s, int start, int count, int after) { // no work to do } }); The query for the database looks like this: public Cursor getCountryList (CharSequence constraint) { if (constraint == null || constraint.length () == 0) { // Return the full list of countries return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, null, null, null, null, KEY_COUNTRYNAME); } else { // Return a list of countries who's name contains the passed in constraint return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, "Country like '%" + constraint.toString () + "%'", null, null, null, "CASE WHEN Country like '" + constraint.toString () + "%' THEN 0 ELSE 1 END, Country"); } } It just seems like there is a missing link somewhere. Any help would be appreciated. Thanks, Ian

The code looks like this: public class Tabs extends TabActivity { int tabNumber = 0; private TabHost tabHost; int returnedTabNumber = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, Tribocracy.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("map").setIndicator("Map", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Areas.class); spec = tabHost.newTabSpec("areas").setIndicator("Areas", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Settings.class); spec = tabHost.newTabSpec("settings").setIndicator("Settings", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(tabNumber); } protected void onResume() { super.onResume(); GlobalData globalData = ((GlobalData)getApplicationContext()); returnedTabNumber = globalData.getTabNumber(); tabHost.setCurrentTab(returnedTabNumber); } } The global adapter looks like this: public class GlobalData extends Application { //---------------------------------------------------- private int Point1; //define the vars here private int Point2; //define the vars here private int Point3; //define the vars here private int Point4; //define the vars here private int Point5; //define the vars here private int Point6; //define the vars here private int tabNumber; public int getTabNumber() //getter of the value { return tabNumber; } public int setTabNumber(int number) //setter of the value { tabNumber = number; return tabNumber; } } Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!

• Android GridView - How to change a bitmap dynamically?

  - by Alborz

  Hello I have a gridView which I use to show some pictures on (small thumb of diffrent levels). When the user finishes one level, I would like to change the thumb for that level. (Somehow show that it has been completed). I created two thumbs for each level. One is the original and one that shows that the level is completed. But how can i change the source of the images? The code which I use to draw the images looks like this. The main activity: /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.maps); GridView gridview = (GridView) findViewById(R.id.gridview); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { //Open the map which was clicked on, if there is one if(position+1 > 1){ Toast.makeText(maps.this, "Level " + (position+1) + " is not yet available!", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(maps.this, "Opening Level " + (position+1), Toast.LENGTH_SHORT).show(); Intent myIntent = new Intent(v.getContext(), Tutorial2D.class); startActivity(myIntent); } } }); } The ImageAdapter Class: public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return mThumbIds.length; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(8, 8, 8, 8); } else { imageView = (ImageView) convertView; } //Changing imageView.setImageResource(mThumbIds[position]); return imageView; } // references to our images private Integer[] mThumbIds = { R.drawable.map1, R.drawable.map2, R.drawable.map3, R.drawable.map4, R.drawable.map5, R.drawable.map6, R.drawable.map7, R.drawable.map8, R.drawable.map9, R.drawable.map10, R.drawable.map11, R.drawable.map12, R.drawable.map13, R.drawable.map14, R.drawable.map15, R.drawable.map16, R.drawable.map17, R.drawable.map18, R.drawable.map19 }; }

• iPhone: Grouped tables and navigation controller issues

  - by Jack Griffiths

  Hi there, I've set up a grouped table on my app, and pushing to new views works fine. Except for one thing. The titles and stack layout are all weird. Here's the breakdown: I have two sections in my table. When I tap on the first row in the first section, it takes me to the correct view, but the title of the new view is the name of the first row in the second section of the table. In turn, the second row in the first section's title is the second row in the second section's title. If I tap on the second row in the second section of the root view table, the navigation button goes to the second row in the first section of the table. So here's a diagram of my table: Table Section 1 Row 1 Row 2 Row 3 Table Section 2 Row A Row B Row C So if I tap on row 3, the title of the pushed view is Row C. The navigation button tells me to go back to Row 3, then eventually ending up at the root view. Here's my implementation file pushing the views: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //CSS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"CSS"]) { CSSViewController *css = [[CSSViewController alloc] initWithNibName:@"CSSViewController" bundle:nil]; [css setTitle:@"CSS"]; [self.navigationController pushViewController:css animated:YES]; } //HTML if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"HTML"]) { HTMLViewController *html = [[HTMLViewController alloc] initWithNibName:@"HTMLViewController" bundle:nil]; [html setTitle:@"HTML"]; [self.navigationController pushViewController:html animated:YES]; } //JS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"JavaScript"]) { JSViewController *js = [[JSViewController alloc] initWithNibName:@"JSViewController" bundle:nil]; [js setTitle:@"JavaScript"]; [self.navigationController pushViewController:js animated:YES]; } //PHP if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"PHP"]) { PHPViewController *php = [[PHPViewController alloc] initWithNibName:@"PHPViewController" bundle:nil]; [php setTitle:@"PHP"]; [self.navigationController pushViewController:php animated:YES]; } //SQL if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"SQL"]) { SQLViewController *sql = [[SQLViewController alloc] initWithNibName:@"SQLViewController" bundle:nil]; [sql setTitle:@"SQL"]; [self.navigationController pushViewController:sql animated:YES]; } & the array feeding the table's data: - (void)viewDidLoad { [super viewDidLoad]; arryClientSide = [[NSArray alloc] initWithObjects:@"CSS",@"HTML",@"JavaScript",nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Objective-C", @"PHP",@"SQL",nil]; // arryResources = [[NSArray alloc] initWithObjects:@"HTML Colour Codes", @"Useful Resources", @"About",nil]; self.title = @"Select a Language"; [super viewDidLoad]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } Any help would be greatly appreciated.

It is just showing a pin in the application with blank screen.

• MVC Bootstrap: Autocomplete doesn't show properly

  - by kicked11

  I have a MVC website and it had a searchbox with autocomplete, now I changed the layout using bootstrap. But now the autocomplete isn't been shown correctly anymore. See the picture the suggestions are not shown right. the autocomplete goes through the text. I was fine before I used bootstrap. I am using a SQL server to get the data and this is js file (I'm not good at ajax, i took it from a tutorial I followed) $(function () { var ajaxFormSubmit = function () { var $form = $(this); var options = { url: $form.attr("action"), type: $form.attr("method"), data: $form.serialize() }; $.ajax(options).done(function (data) { var $target = $($form.attr("data-aptitude-target")); var $newHtml = $(data); $target.replaceWith($newHtml); $newHtml.show("slide", 200); }); return false; }; var submitAutocompleteForm = function (event, ui) { var $input = $(this); $input.val(ui.item.label); var $form = $input.parents("form:first"); $form.submit(); }; var createAutocomplete = function () { var $input = $(this); var options = { source: $input.attr("data-aptitude-autocomplete"), select: submitAutocompleteForm }; $input.autocomplete(options); }; $("form[data-aptituder-ajax='true']").submit(ajaxFormSubmit); $("input[data-aptitude-autocomplete]").each(createAutocomplete); }); this is the form in my view <form method="get" action="@Url.Action("Index")" data-aptitude-ajax="true" data-aptitude-target="#testList"> <input type="search" name="searchTerm" data-aptitude-autocomplete="@Url.Action("Autocomplete")" /> <input type="submit" value=Search /> And this is part of the controller of the view public ActionResult Autocomplete(string term) { var model = db.tests .Where(r => term == null || r.name.Contains(term)) .Select(r => new { label = r.name }); return Json(model, JsonRequestBehavior.AllowGet); } // // GET: /Test/ public ActionResult Index(string searchTerm = null) { var model = db.tests .Where(r => searchTerm == null || r.name.StartsWith(searchTerm)); if (Request.IsAjaxRequest()) { return PartialView("_Test", model); } return View(model); } I'm new to ajax as well as bootstrap 3. I got the searchfunction and autocomplete from a tutorial I followed. Anybody any idea on how to fix this, because it worked fine? Thanks in advance!

  Hi, when i try to use in my ASPX Webpage in the Code Behind this try{ while() { ... db.Open(); readDataMoney = new OleDbCommand("SELECT * FROM Customer WHERE card = '" + customer.card + "';", db).ExecuteReader(); while (readDataMoney.Read()) { try { if (!readDataMoney.IsDBNull(readDataMoney.GetOrdinal("Credit"))) { customer.credit = Convert.ToDouble(readDataMoney[readDataMoney.GetOrdinal("Credit")]); } if (!readDataMoney.IsDBNull(readDataMoney.GetOrdinal("Bonus"))) { customer.bonus = Convert.ToDouble(readDataMoney[readDataMoney.GetOrdinal("Bonus")]); } } catch (Exception ex) { Connector.writeLog("Money: " + ex.StackTrace + "" + ex.Message + "" + ex.Source); customer.credit = 0.0; customer.credit = 0.0; continue; } finally { } } readDataMoney.Close(); vsiDB.Close(); ... } }catch { continue; } The whole page hangs if there is a problem when the read from db isn't working. I tried to check for !isNull, but same problem. I have a lots of differend MDB Files to process, which are readonly (can't repair/compact) and some or others not. Same Design/Layout of Tables. With good old ASP Classic 3.0 all of them are processing with the "On Resume Next". I know I know. But that's how it is. Can't change the source. So the basic question: So is there any way to tell .NET to continue the loop whatever happens within the try loop if there is any exception?

• Navigation bar(s) disappear when the window gets too small

  - by Leron

  The title maybe is a little misleading but I'm not 100% sure how this effect is called. I'm pretty sure what I meant is that my navigation bar is disappearing instead of collapsing. However my set up is this - I am working on the Layout view of ASP.NET MVC 4 project. I'm using bootstrap 3x but also have included jQuery libs so my <head> part is like this: @Scripts.Render("~/Scripts/bootstrap.min.js") @Styles.Render("~/Content/bootstrap.css") @Styles.Render("~/Content/themes/base/jquery.ui.smoothness.css") @Scripts.Render("~/Scripts/jquery-2.0.3.min.js") @Scripts.Render("~/Scripts/jquery-ui-1.10.3.min.js") //just skipped the standard stuff In the body I want to have two navbars and one side menu which will be the same for all my pages but I've noticed that when I start to narrow the window at some point instead of getting an effect similar to this example (noticed how the elements get repositioned) I just got both my navbars gone, I can't see them. The markup for my first navbar is this : <div class="navbar navbar-static-top navbar-inverse navbar-collapse collapse" role="navigation"> <ul class="nav navbar-nav "> <li><a href="#">Info</a></li> <li><a href="#">Info</a></li> </ul> </div> and the second one is : <div class="navbar navbar-collapse collapse" role="navigation" id="main-navigation-bar"> <ul class="nav nav-pills nav-justified"> <li style="border: 1px solid grey"><a href="#">Link</a></li> <li><a href="#">Link</a></li> <li><a href="#">Link</a></li> </ul> In fact the only thing left in my _Layout body is this: <div class="container-fluid"> @RenderBody() </div> which is just for compiling purposes and renders this view : <p>1</p> <p>2</p> <p>3</p> <p>4</p> <p>5</p> So when I make the window small enough so that my navbars disappear the only thing left is 1..5 numbers from the rendered view. I tested with only one navbar (commented the other) - no matter which one is commented, when I narrow the window I loose the navbar. How can I keep them using bootstrap 3x?

• How do I use data from the main window in a sub-window?

  - by eagle

  I've just started working on a photo viewer type desktop AIR app with Flex. From the main window I can launch sub-windows, but in these sub-windows I can't seem to access the data I collected in the main window. How can I access this data? Or, how can I send this data to the sub-window on creation? It doesn't need to be dynamically linked. myMain.mxml <?xml version="1.0" encoding="utf-8"?> <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="260" height="200" title="myMain"> <fx:Declarations> </fx:Declarations> <fx:Script> <![CDATA[ public function openWin():void { new myWindow().open(); } public var myData:Array = new Array('The Eiffel Tower','Paris','John Doe'); ]]> </fx:Script> <s:Button x="10" y="10" width="240" label="open a sub-window" click="openWin();"/> </s:WindowedApplication> myWindow.mxml <?xml version="1.0" encoding="utf-8"?> <mx:Window name="myWindow" title="myWindow" xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="640" height="360"> <mx:Script> <![CDATA[ ]]> </mx:Script> <mx:Label id="comment" x="10" y="10" text=""/> <mx:Label id="location" x="10" y="30" text=""/> <mx:Label id="author" x="10" y="50" text=""/> </mx:Window> I realize this might be a very easy question but I have searched the web, read and watched tutorials on random AIR subjects for a few days and couldn't find it. The risk of looking like a fool is worth it now, I want to get on with my first app!

• Stretch panel with splitter

  - by user1153896

  I want to implement a basic WPF layout with three panels and two splitters (Horizontal and Vertical splitter). Two panels on the left and on the bottom has to be callapsable and one panel has to stretch accordingly. Here is a simple XAML: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="5"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Background="Aqua" Grid.Column="0" Name="leftPanel" > <TextBlock FontSize="35" Foreground="#58290A" TextWrapping="Wrap">Left Hand Side</TextBlock> </StackPanel> <GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/> <Grid Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="5" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Label Content="... Clien Area .. Has to Stretch vertically and horizontally" Margin="10"></Label> <Button Click="LeftButton_Click" Margin="10">Close Left Panel</Button> <Button Click="BottomButton_Click" Margin="10">Close Bottom Panel</Button> </StackPanel> <GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/> <ListBox Grid.Row="2" Background="Violet" Name="bottomPanel"> <ListBoxItem>Hello</ListBoxItem> <ListBoxItem>World</ListBoxItem> </ListBox> </Grid> </Grid> and codebehind: private void LeftButton_Click(object sender, RoutedEventArgs e) { leftPanel.Visibility = (leftPanel.Visibility == System.Windows.Visibility.Visible)? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } private void BottomButton_Click(object sender, RoutedEventArgs e) { bottomPanel.Visibility = (bottomPanel.Visibility == System.Windows.Visibility.Visible) ? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } This code doesn't work as expected :(. Any WPF experts around? to suggest a solution for having Client Area (stretched) and splitter at the same time? DockPanel will work perfectly, but I need splitter! Thanks.
