• WebView inside Tab hiding the tabWidgets

  - by brockoli

  I'm having trouble with a WebView always filling the full screen and thus covering my tabs. Here is my code for the tabhost.. public class tabNZBMobile extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable 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, NewzbinMobile.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("search").setIndicator("Search", res.getDrawable(R.drawable.ic_tab_search)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, sabnzbWeb.class); spec = tabHost.newTabSpec("sabnzbweb").setIndicator("SabNZBd", res.getDrawable(R.drawable.ic_tab_sabnzbweb)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTabByTag("search"); }} My first tab (NewzbinMobile.class) displays correctly, it's just a relativelayout. But my second tab is an activity showing a webview and it is showing, but using the whole screen, covering my tabs. Here is the code for my second tab. public class sabnzbWeb extends Activity { WebView mWebView; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String sabNZBurl = new String("http://test.server.org:8080/m"); mWebView = new WebView(this); mWebView.getSettings().setJavaScriptEnabled(true); setContentView(mWebView); mWebView.loadUrl(sabNZBurl); }}

• MSBuild "Wrapper" fails while VS2010 "Pure" compile succeeds for MFC application in CruiseControl.NE

  - by ee

  The Overview I am working on a Continuous Integration build of a MFC appliction via CruiseControl.net and VS2010. When building my .sln, a "Visual Studio" CCNet task (devenv) works, but a wrapper MSBuild script run via the CCNet MSBuild task fails with errors like: error RC1015: cannot open include file 'winres.h'.. error C1083: Cannot open include file: 'afxwin.h': No such file or directory error C1083: Cannot open include file: 'afx.h': No such file or directory The Question How can I adjust the build environment of my msbuild wrapper so that the application builds correctly? (Pretty clearly the MFC paths aren't right for the msbuild environment, but how do i fix it for MSBuild+VS2010+MFC+CCNet?) Background Details We have successfully upgraded an MFC application (.exe with some MFC extension .dlls) to Visual Studio 2010 and can compile the application without issue on developer machines. Now I am working on compiling the application on the CI server environment I did a full installation of VS2010 (Professional) on the build server. In this way, I knew everything I needed would be on the machine (one way or another) and that this would be consistent with developer machines. VS2010 is correctly installed on the CI server, and the devenv task works as expected I now have a wrapper MSBuild script that does some extended version processing and then builds the .sln for the application via an MSBuild task. This wrapper script is run via CCNet's MSBuild task and fails with the above mentioned errors My Assumptions This seems to be a missing/wrong configuration of include paths to standard header resources of the MFC persuasion I should be able to coerce the MSBuild environment to consider the relevant resource files from my VS2010 install and have this approach work. But how do I do that? Am I setting Environment variables? Registry settings? I can see how one can inject additional directories in some cases, but this seems to need a more systemic configuration at the compiler defaults level.

• Perl XML SAX parser emulating XML::Simple record for record

  - by DVK

  Short Q summary: I am looking a fast XML parser (most likely a wrapper around some standard SAX parser) which will produce per-record data structure 100% identical to those produced by XML::Simple. Details: We have a large code infrastructure which depends on processing records one-by-one and expects the record to be a data structure in a format produced by XML::Simple since it always used XML::Simple since early Jurassic era. An example simple XML is: <root> <rec><f1>v1</f1><f2>v2</f2></rec> <rec><f1>v1b</f1><f2>v2b</f2></rec> <rec><f1>v1c</f1><f2>v2c</f2></rec> </root> And example rough code is: sub process_record { my ($obj, $record_hash) = @_; # do_stuff } my $records = XML::Simple->XMLin(@args)->{root}; foreach my $record (@$records) { $obj->process_record($record) }; As everyone knows XML::Simple is, well, simple. And more importantly, it is very slow and a memory hog - due to being a DOM parser and needing to build/store 100% of data in memory. So, it's not the best tool for parsing an XML file consisting of large amount of small records record-by-record. However, re-writing the entire code (which consist of large amount of "process_record"-like methods) to work with standard SAX parser seems like an big task not worth the resources, even at the cost of living with XML::Simple. What I'm looking for is an existing module which will probably be based on a SAX parser (or anything fast with small memory footprint) which can be used to produce $record hashrefs one by one based on the XML pictured above that can be passed to $obj->process_record($record) and be 100% identical to what XML::Simple's hashrefs would have been.

• Modularity in Flex

  - by Fernando

  I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

• .NET load assembly error metabase config

  - by peter

  Hi, Yesterday I found out that the mailroot directory had moved to a different location on the C drive. I don't know how this happened as no configs were changed, using IIS7 with IIS6 SMTP service on Windows 2008 R2 web edition. I wanted to restore it to the default c:\inetpub\mailroot location. So I opened system32/inetsrv/MetaBase.xml, and in the node was the problem, BadMailDirectory, DropDirectory etc were all pointing to the wrong location... I changed them back to the default c:\inetpub\mailroot. Later I discovered an ASP.NET application was throwing this error: An error occurred in the Microsoft .NET Framework while trying to load assembly id 1. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error: System.IO.FileNotFoundException: Could not load file or assembly 'microsoft.sqlserver.types, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified. I figured it had to do with my changes to the mailroot locations, so I gave ASP.NET access to the mailroot directory and it was working.... My question is, how is this possible? Why does APS.NET require access to the mailroot directory to load assemblies? Thanks

• Creating cookieless application on development machine with asp.net

  - by zaladane

  I tried posting this on ServerFault with no luck so i am trying here. I am thinking about setting up a new domain to host static content on my website and have it cookieless just like Stackoverflow with their static domain. So before going ahead and buying the domain and setting it up I wanted to test it on my developement machine first under localhost (I have to mention that i am planning on having IIS running on my new domain for the static files). I therefore created a new application under IIS and disabled session state and forms authentication. When my main application needs resources like css, images and js , I use the path to the "static" application where they are hosted. The problem is that when I look at the request and the response for the requested files, they still have the session_id cookie defined as well as the asp.net authentication cookie. Is it at all possible to accomplish what i am trying to do on a development machine or do i have to just go ahead and purchase the new domain which hopefully with make things right? I tried to read about cookieless domain but can't figure out what i might be missing.

• sqlite3 no insert is done after --> insert into --> SQLITE_DONE

  - by Fra

  Hi all, I'm trying to insert some data in a table using sqlite3 on an iphone... All the error codes I get from the various steps indicate that the operation should have been successful, but in fact, the table remains empty...I think I'm missing something... here the code: sqlite3 *database = nil; NSString *dbPath = [[[ NSBundle mainBundle ] resourcePath ] stringByAppendingPathComponent:@"placemarks.sql"]; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK){ sqlite3_stmt *insert_statement = nil; //where int pk, varchar name,varchar description, blob picture static char *sql = "INSERT INTO placemarks (pk, name, description, picture) VALUES(99,'nnnooooo','dddooooo', '');"; if (sqlite3_prepare_v2(database, sql, -1, &insert_statement, NULL) != SQLITE_OK) { NSAssert1(0, @"Error: failed to prepare statement with message '%s'.", sqlite3_errmsg(database)); } int success = sqlite3_step(insert_statement); int finalized = sqlite3_finalize(insert_statement); NSLog(@"success: %i finalized: %i",success, finalized); NSAssert1(101, @"Error: failed to insert into the database with message '%s'.", sqlite3_errmsg(database)); sqlit3_step returns 101, so SQLITE_DONE, which should be ok.. If I execute the sql statement in the command line it works properly... anyone has an idea? could it be that there's a problem in writing the placemarks.sql because it's in the resources folder? rgds Fra

• WPF toolbar disappearing on resize

  - by user1122909

  On my main form I have a toolbar with a number of buttons. Once the parent form is resized down by dragging it so that the entire toolbar with all its buttons no longer fits in the width of the window, the whole toolbar disappears. Is there a way I can make it so that as you resize it, when you get to the width of the toolbar the inner controls of the form stop resizing and stay displayed, just cut off where the window has resized to? Code is <Grid > <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <ToolBar Grid.Row="1" Height="50" Name="tbMainToolbar" VerticalAlignment="Top" MinWidth="900" > <ToolBar.Background> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="White" Offset="0.0" /> <GradientStop Color="#DCEBFF" Offset="0.25" /> <GradientStop Color="#99CCFF" Offset="0.75" /> <GradientStop Color="#99CCFF" Offset="1.0" /> </LinearGradientBrush> </ToolBar.Background> <DockPanel LastChildFill="True"> <Button Name="btnApproved" DockPanel.Dock="Left" Click="btnToolbar_Click" CommandParameter="APPROVED" Style="{StaticResource ToolbarButtonDisplay}" HelperClasses:ButtonProperties.Image="..\..\Resources\Images\APPROVEU.GIF" Content="Approve"> </Button> ... and so forth for about 20 buttons

• Replacing/Extending Visual Studio's Generate Stub in Visual Studio 2010

  - by devoured elysium

  When we write the name of a method that doesn't exist, Visual Studio 2010 asks us if we'd like to generate a method stub with that name. What I'd like to know if is it possible to replace that same code stub generating command with one made by myself. I never did any kind of extensibility programming for Visual Studio so I have a couple of questions: How hard is it? Is it something I can learn in a couple of nights, or is it something that'll make me "lose" a lot of time? It seems to me that there isn't a lot of support for that kind of programming, as generally people are not that interested in developing solutions that extend the Visual Studio IDE. I searched on SO and it doesn't appear to have many threads about extending Visual Studio. I don't know how the generate method stub thing works in Visual Studio, but I just wanted to turn it into something a bit more flexible and useful. Has anyone dealt with these kind of things before, that can give me a pointer to where to start? I know of MS VSX site but that has a lot of resources and can be overwhelming for someone new to the subject as I am. What technology will I need to use? T4? Maybe I'll need to know a lot about the code, like Visual Studio does, so I can know other method's type arguments, names, etc. Is that what T4 is for? Thanks

• Databinding question: DataGridView <=> XDocument (using LINQ-to-XML)

  - by Pretzel

  Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• SharePoint 2007 and SiteMinder

  - by pborovik

  Here is a question regarding some details how SiteMinder secures access to the SharePoint 2007. I've read a bunch of materials regarding this and have some picture for SharePoint 2010 FBA claims-based + SiteMinder security (can be wrong here, of course): SiteMinder is registered as a trusted identity provider for the SharePoint; It means (to my mind) that SharePoint has no need to go into all those user directories like AD, RDBMS or whatever to create a record for user being granted access to SharePoint - instead it consumes a claims-based id supplied by SiteMinder SiteMinder checks all requests to SharePoint resources and starts login sequence via SiteMinder if does not find required headers in the request (SMSESSION, etc.) SiteMinder creates a GenericIdentity with the user login name if headers are OK, so SharePoint recognizes the user as authenticated But in the case of SharePoint 2007 with FBA + SiteMinder, I cannot find an answer for questions like: Does SharePoint need to go to all those user directories like AD to know something about users (as SiteMinder is not in charge of providing user info like claims-based ids)? So, SharePoint admin should configure SharePoint FBA to talk to these sources? Let's say I'm talking to a Web Service of SharePoint protected by SiteMinder. Shall I make a Authentication.asmx-Login call to create a authentication ticket or this schema is somehow changed by the SiteMinder? If such call is needed, do I also need a SiteMinder authentication sequence? What prevents me from rewriting request headers (say, manually in Fiddler) before posting request to the SharePoint protected by SiteMinder to override its defence? Pity, but I do not have access to deployed SiteMinder + SharePoint, so need to investigate some question blindly. Thanks.

• Newbie question: How do you layout an icon, 2 text lines and a button?

  - by Keith Barrows

  I am trying to extend a sample I found at http://developer.android.com/resources/articles/layout-tricks-efficiency.html. I am a brand new MonoDroid developer, just installed it yesterday, and trying to jump right into UI design and so far it is not clicking for me completely. I have this main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="200dip" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Second line which is a long line of text and needs to scroll" /> <TextView android:id="@+id/firstLine" android:layout_width="200dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" android:text="First line" /> <Button android:id="@+id/logonButton" android:layout_width="50dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/secondLine" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:gravity="center_vertical" android:text="Login" /> /> </RelativeLayout> What I am trying to do is have an icon on the left, 2 lines of text stacked in the middle and a button on the right. When I run this in my emulator I am seeing: The second line is not scrolling. The button does not show up. Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine. Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)

• Why does jQuery.ajax() add a parameter to the url?

  - by FK82

  Hi, I have a data fetching method that uses jQuery.ajax() to fetch xml files. /* */data: function() { /* debug */try { var url = arguments[0] ; var type = arguments[1] ; var scope = arguments[2] ; var callback = arguments[3] ; var self = this ; if(this.cache[url]) { callback(this.cache[url]) ; } else if(!this.cache[url]) { $.ajax({ type: "GET" , url: url , dataType: type , cache: false , success: function(data) { if(type == "text/xml") { var myJson = AUX.json ; var jsonString = myJson.build(data,scope,null) ; var jsonObject = $.parseJSON(jsonString) ; self.cache[url] = jsonObject ; callback(url) ; } else if(type == "json") { self.cache[url] = data ; callback(url) ; } } , error: function() { throw "Ajax call failed." ; } }) ; } /* debug */} catch(e) { /* debug */ alert("- caller: signTutor.data\n- " + e) ; /* debug */} } , My problem is: jQuery somehow adds a parameter (?_=1272708280072) to the url if there are escaped (hexadecimal notation) or unescaped utf-8 characters outside of the ASCII range -- i believe -- in the file name. It all works well if the file name does not contain characters in that range. Type is set to xml so there should not be a confusion of types. Headers of the xml files are also set adequately. I can see from the console that jQuery throws an error, but I'm not sure as to where the problem really is. Probably a problem with file name formatting, but I did not find any resources on the web as to AJAX file name specifications. Any ideas? Thanks for you help!

• compile ICS/JB camera application - native library jni-mosaic error

  - by liorry

  I would like to use the Panorama mode that the ICS/JB camera application has. I've downloaded the source code (with resources) and managed to solve all code compilation errors but as soon as I start the application on my device (running JB), I get this error: 10-25 14:42:53.617: E/AndroidRuntime(23147): FATAL EXCEPTION: GLThread 2586 10-25 14:42:53.617: E/AndroidRuntime(23147): java.lang.UnsatisfiedLinkError: Native method not found: com.app.camera.panorama.MosaicRenderer.reset:(IIZ)V 10-25 14:42:53.617: E/AndroidRuntime(23147): at com.app.camera.panorama.MosaicRenderer.reset(Native Method) 10-25 14:42:53.617: E/AndroidRuntime(23147): at com.app.camera.panorama.MosaicRendererSurfaceViewRenderer.onSurfaceChanged(MosaicRendererSurfaceViewRenderer.java:49) 10-25 14:42:53.617: E/AndroidRuntime(23147): at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1505) 10-25 14:42:53.617: E/AndroidRuntime(23147): at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240) I do have a libjni-mosaic lib, located in armeabi-v7a/armeabi/x86 and it seems to load it fine but it probably doesn't contain the methods the MosaicRenderer implements. I also tried compiling the CyanogenMod camera app https://github.com/CyanogenMod/android_packages_apps_Camera/tree/ics but I get the same error... The camera itself works, for stills and video recording but as soon as I change to panorama mode, it crashes. Can anyone maybe point me to the right jni-mosaic lib or maybe to what I'm doing wrong? Do I need to do something in order to make my app use the JNI/SO files?

• How do I grant anonymous access to a url using FormsAuthentication?

  - by Brian Bolton

  For the most part, my webapp requires authentication to do anything. There are a few pages, namely the homepage, that I'd like people to be able to access without authenticating. Specifically, I'd like to allow anonymous access to these urls: /home /default.aspx I'm using asp.net MVC and FormsAuthentication. Both urls point to the same view: /home/index.aspx Here is my current configuration in web.config. <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <authorization> <deny users="?" /> </authorization> Reading the documentation for the authorization tag, it says "Configures the authorization for a Web application, controlling client access to URL resources." It seems like I should be able to use the authorization tag to specify a url and allow access. Something like: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <authorization> <deny users="?" /> </authorization> <authorization url="/default.aspx"> <allow users="?" /> </authorization> <authorization url="/home"> <allow users="?" /> </authorization>

• Newbie database index question

  - by RenderIn

  I have a table with multiple indexes, several of which duplicate the same columns: Index 1 columns: X, B, C, D Index 2 columns: Y, B, C, D Index 3 columns: Z, B, C, D I'm not very knowledgeable on indexing in practice, so I'm wondering if somebody can explain why X, Y and Z were paired with these same columns. B is an effective date. C is a semi-unique key ID for this table for a specific effective date B. D is a sequence that identifies the priority of this record for the identifier C. Why not just create 6 indexes, one for each X, Y, Z, B, C, D? I want to add an index to another column T, but in some contexts I'll only be querying on T alone while in others I will also be specifying the B, C and D columns... so should I create just one index like above or should I create one for T and one for (T, B, C, D)? I've not had as much luck as expected when googling for comprehensive coverage of indexing. Any resources where I can get a through explanation and lots of examples of B-tree indexing?

• Offline iOS web app: loads my manifest, but doesn't work offline

  - by Ken

  I'm writing a web app to be used offline on iOS. I've created a manifest, am serving it up as text/cache-manifest, and it usually works fine, when running inside Safari. If I add it as an app to my home screen, then turn on Airplane mode, it can't open the app at all -- I get an error and it offers to close the app. (I thought this was the entire purpose of an offline app!) When I load the app a first time when online, I can see in my logs that it's requesting every page listed in the manifest. If I turn off Airplane mode, and load the app, I can see the first file it's requesting is my main.html file (which is both listed in the manifest, and has the manifest=... attribute). It then requests the manifest, and all my other files, getting 200's for all (and 304's for anything requested a second time during this load). When I load the page in Chrome, and click around, the logs show the only thing it's trying to reach on the server is "/favicon.ico" (which is a 404, and which I don't think iOS Safari tries to load, anyway). All of the files listed in the manifest are valid and served without error. The Chrome inspector lists, under "APPLICATION CACHE", all the cached files I've listed which I expect. The entire set of files is about 50 KB, way under any limit on offline resources that I've found. Is this supposed to work, i.e., am I supposed to be able to create an offline iOS app using only HTML/CSS/JS? And where do I go about figuring out why it's failing to work offline? (Related but doesn't sound quite the same to me, since it's about Safari and not a standalone app: "Can't get a web app to work offline on iPod")

• how to combine widget webapp framework with SEO-friendly CSS and JS files

  - by Ali

  Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

I'm trying to build a really simple iPhone application and I am confused by the way that views work in general. If someone can provide advice for my particular problem, along with some resources where I can learn how to architect iPhone views in the future, that would be awesome. I feel like a lot of the Apple documentation that I've come across is too specific - I am lacking a fundamental understanding of how views work on the iPhone. My particular problem looks like this: I need one view that displays some downloaded text content. This is the view that shows when the app loads, and it is pretty straightforward. Then I need a settings area (I've already decided I don't want to use the iPhone settings area). The settings area main page will have some text fields on it. It will also have a 2-row grouped table. Each cell in that table will take you to another view which also has a grouped table used for multi-select. I suspect that I can reuse the same view for these two final "detailed setting" views. In summary: home page settings main page detailed setting 1 detailed setting 2 Any help and advice appreciated.

• datanucleus enhancer & javaw: "the parameter is incorrect"

  - by Riley

  I'm on windows XP using eclipse and the datanucleus enhancer for a gwt + gae app. When I run the enhancer, I get an error: Error Thu Oct 21 16:33:57 CDT 2010 Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect at java.lang.ProcessBuilder.start(Unknown Source) at com.google.gdt.eclipse.core.ProcessUtilities.launchProcessAndActivateOnError(ProcessUtilities.java:213) at com.google.appengine.eclipse.core.orm.enhancement.EnhancerJob.runInWorkspace(EnhancerJob.java:154) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.io.IOException: CreateProcess error=87, The parameter is incorrect at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.<init>(Unknown Source) at java.lang.ProcessImpl.start(Unknown Source) ... 5 more I've had this problem before, and it was due to a long classpath. I just spent an hour and a half shortening my classpath by moving libraries around and even moving my eclipse install, but with no luck. Any ideas about where I should start to look for an answer? The error message doesn't include any information about what directory it's in or anything. It's kind of infuriating! Is it possible to make the output of javaw more verbose? Is it possible to get around this class-path size bug?

• Opengl-es draw an .obj file, but how?

  - by lacas

  I d like to parse an .obj file. My parser is working good, but my displaying is not good. Obj file is here my code is: public ObjModelParser parse() { long startTime = System.currentTimeMillis(); InputStream fileIn = resources.openRawResource(resourceID); BufferedReader buffer = new BufferedReader(new InputStreamReader(fileIn)); String line=""; Log.e("model loader", "Start parsing object " + resourceID); try { while ((line = buffer.readLine()) != null) { StringTokenizer parts = new StringTokenizer(line, " "); int numTokens = parts.countTokens(); if (numTokens == 0) continue; String part = parts.nextToken(); if (part.equals(VERTEX)) { Log.e("v ", line); vertices.add(Float.parseFloat(parts.nextToken())); vertices.add(Float.parseFloat(parts.nextToken())); vertices.add(Float.parseFloat(parts.nextToken())); .... and my displaying code is: draw that model with TRIANGLE_STRIP and gl.glDrawArrays(rendermode, 0, coords.length/dimension); What is the mistake here? edited: file here to show what is my good coords from my program for a cube, and what is from .obj file, that never show Thanks, Leslie

• Multiple connections in a single SSH SOCKS 5 Proxy

  - by Elie Zedeck

  Hey guys, My fist question here on Stackoverflow: What should I need to do so that the SSH SOCKS 5 Proxy (SSH2) will allow multiple connections? What I have noticed, is that when I load a page in Firefox (already configured to use the SOCKS 5 proxy), it loads everything one by one. It can be perceived by bare eyes, and I also confirm that through the use of Firebug's NET tab, which logs the connections that have been made. I have already configure some of the directives in the about:config page, like pipeline, persistent proxy connections, and a few other things. But I still get this kind of sequential load of resources, which is noticeably very slow. network.http.pipelining;true network.http.pipelining.maxrequests;8 network.http.pipelining.ssl;true network.http.proxy.pipelining;true network.http.max-persistent-connections-per-proxy;100 network.proxy.socks_remote_dns;true My ISP sucks because during the day, it intentionally breaks connections on a random basis. And so, it is impossible to actually accomplish meaningful works without the need of a lot of browser refresh or hitting F5 key. So, that is why I started to find solutions to this. The SSH's dynamic port forwarding is the best solution I find to date, because it has some pretty good compression which saves a lot of useless traffic, and is also secure. The only thing remaining is to get it to have multiple connections running in it. Thanks for all the inputs.

• OpenGL/Carbon/Cocoa Memory Management Autorelease issue

  - by Stephen Furlani

  Hoooboy, I've got another doozy of a memory problem. I'm creating a Carbon (AGL) Window, in C++ and it's telling me that I'm autorelease-ing it without a pool in place. uh... what? I thought Carbon existed outside of the NSAutoreleasePool... When I call glEnable(GL_TEXTURE_2D) to do some stuff, it gives me a EXC_BAD_ACCESS warning - but if the AGL Window is never getting release'd, then shouldn't it exist? Setting set objc-non-blocking-mode at (gdb) doesn't make the problem go away. So I guess my question is WHAT IS UP WITH CARBON/COCOA/NSAutoreleasePool? And... are there any resources for Objective-C++? Because crap like this keeps happening to me. Thanks, -Stephen --- CODE --- Test Draw Function void Channel::frameDraw( const uint32_t frameID) { eq::Channel::frameDraw( frameID ); getWindow()->makeCurrent(false); glEnable(GL_TEXTURE_2D); // Throws Error Here } Make Current (Equalizer API from Eyescale) void Window::makeCurrent( const bool useCache ) const { if( useCache && getPipe()->isCurrent( this )) return; _osWindow->makeCurrent(); } void AGLWindow::makeCurrent() const { aglSetCurrentContext( _aglContext ); AGLWindowIF::makeCurrent(); if( _aglContext ) { EQ_GL_ERROR( "After aglSetCurrentContext" ); } } _aglContext is a valid memory location (i.e. not NULL) when I step through. -S!
