  • SIGABRT error when running MonoTouch application

    - by hambonious
    I'm new to MonoTouch and 9 times out of 10, when I try to run my MonoTouch app on the iPhone simulator (debug mode and regular), I receive a long error output that begins with the following message: Error connecting stdout and stderr (127.0.0.1:10001) Couldn't register com.yourcompany.[appnamehere] with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Stacktrace: at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at MonoTouch.UIKit.UIApplication.Main (string[],string,string) <0x00089 at MonoTouch.UIKit.UIApplication.Main (string[]) <0x00014 at PodcastManager.Application.Main (string[]) <0x00010 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) <0x00043 And ends with: ================================================================= Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= The weird thing is it will work some of the time. Once, a reboot of my machine did it. Others, just restarting MonoDevelop and/or the simulator. I can provide the entire error output if you think that may help. Any ideas?

  • White dialog theme

    - by Al
    I've noticed some apps have a dialog with white background, including along the title border, as opposed to the default black. I know how to make the background white but the whiteness doesn't extend to the dialog's title border. This image: http://localhostr.com/files/25bb19/tether.png is an example of how I want the dialog to look. Anyone know I can do this? I mainly use AlertDialog.Builder to make my dialogs so ideally something I can easily to that.

  • Application running in the iPad Simulator

    - by Wallym
    I've got some code running in the iPad Simulator.  One thing I discovered is that an application has to be compiled against a specific version of the SDK.  When I created a new iPad application, the updated iPad window for the Interface Builder became availble.  Very nice indeed.  Everything was the same as before, so that was good.  I fired up the iPad Simulator, and I got this below:   The next step was getting my app on there, which was easy.  Then I got my app running on the simulator, and I saw this: Basically, everything is filled with goodness and seems to be running correctly.  **fingers crossed**

  • How to use SharePoint modal dialog box to display Custom Page Part1

    - by ybbest
    In the part1 of this series, I will show you how to use the modal dialog box to display the custom page and close the page. You can download solution here. 1. Firstly, I create custom action on the list item ECB called Display Custom Page. To do so, you need to create an element item in SharePoint project and copy the following xml to the element file. <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <CustomAction Id="ReportConcern" RegistrationType="ContentType" RegistrationId="0x010100866B1423D33DDA4CA1A4639B54DD4642" Location="EditControlBlock" Sequence="107" Title="Display Custom Page" Description="To Display Custom Page in a modal dialog box on this item"> <UrlAction Url="javascript: function CallDETCustomDialog(dialogResult, returnValue) { SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK); } var options = { url: '{SiteUrl}' + '/_layouts/YBBEST/TitleRename.aspx?List={ListId}&amp;ID={ItemId}', title: 'Rename title', allowMaximize: false, showClose: true, width: 500, height: 300, dialogReturnValueCallback: CallDETCustomDialog }; SP.UI.ModalDialog.showModalDialog(options);" /> </CustomAction> </Elements> 2. In your code behind, you can implement a close dialog function as below. This will close your modal dialog box once the button is clicked. protected void CloseDialog() { if (HttpContext.Current.Request.QueryString["IsDlg"] == null) return; if (!ClientScript.IsStartupScriptRegistered("CloseDialogFunction")) { const string script = "<script type='text/javascript'>" + "SP.UI.ModalDialog.commonModalDialogClose(1, 1);" + "</script>"; ClientScript.RegisterStartupScript(GetType(), "CloseDialogFunction", script); } }

  • jquery dialog - which button opened the dialog?

    - by Dan
    In the example below, how can you use the event and ui objects to detect which link opened the dialog? Can't seem to get $(event.target).attr("title"); to work properly, and I'm having trouble finding documentation on the 'ui object that is passed. Thanks! $( ".selector" ).dialog({ link_title = $(event.target).attr("title"); alert(link_title); }); $("a").live("click", function() { btn_rel = $(this).attr("rel"); $(btn_rel).dialog("open"); }); <a class="btn pencil" rel="#dialog_support_option_form" title="Edit Support Option">Edit</button>

  • JQuery UI Dialog query dialog DOM

    - by Travis
    The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

  • Installing MonoTouch - ibtool not found error

    - by Nic Wise
    I've had Xcode (3.2.1 - SnowLeopard, iphone 3.1.3) installed for a while, and I can run and build apps on it fine. I installed MonoTouch, as I want to leverage the 8+ years of .NET skills I have :) So I installed: Mono: MonoFramework-2.6.1_1.macos10.novell.x86 MonoTouch: monotouch-eval-1.5.0 MonoDevelop: MonoDevelop-2.2.1-r152508 (was 2.2.1, but when I started it up, it said there was an update, which I installed - thats the update version) If I make a new project and build it, I get any of the following errors: Build failed. Object reference not set to the instance of an object. Build failed: ibtool not found (btw, it's in /Developer/usr/bin/ibtool) or a similar one to the second one if I use the older (2.2.1 released) version of MonoTouch. I can't find any debug info anywhere. I could reinstall XCode/iPhone SDK, but as it already is installed and works (and no, this isn't a SL upgrade), it doesn't make sense. Anyone got any ideas? I SO want to use MonoTouch - Obj-C drives me up the wall! Console apps (mono ones) work fine. Mac OS X 10.6.2, Macbook Pro, clean install with old settings moved over.

  • Using Monotouch with Google .NET APIs

    - by Bryan
    I am using Mike Bluestein's article, http://mikebluestein.wordpress.com/2009/09/27/using-monotouch-with-the-net-library-for-the-google-data-api/, to build an application that communicates with the google APIs. When I try to add references to my project, the imported projects say "incompatible target framework: v2.0". I can change version to 1.0, 3.0, or 3.5 with the same results. If I add the .dll to the monotouch project I get a compilation error - monotouch failed with no output 134. Any suggestions?

  • Monotouch UITableView image "flashing" while background requests are fetched

    - by Themos Piperakis
    I am in need of some help from you guys. I have a Monotouch UITableView which contains some web images. I have implemented a Task to fetch them asynchronously so the UI is responsive, an even added some animations to fade them in when they are fetched from the web. My problems start when the user scrolls down very fast down the UITableView, so since the cells are resusable, several background tasks are queued for images. When he is at the bottom of the list, he might see the thumbnail displaying an image for another cell, then another, then another, then another, as the tasks are completed and each image replaces the other one. I am in need of some sort of checking whether the currently displayed cell corresponds to the correct image url, but not sure how to do that. Here is the code for my TableSource class. using System; using MonoTouch.UIKit; using MonoTouch.Foundation; using System.Collections.Generic; using System.Threading; using System.Threading.Tasks; using System.Diagnostics; { public class ListDelegate:UITableViewDelegate { private UINavigationController nav; public override float GetHeightForRow (UITableView tableView, NSIndexPath indexPath) { return 128; } public override void RowSelected (UITableView tableView, NSIndexPath indexPath) { DealViewController c = new DealViewController(((ListDataSource)tableView.DataSource).deals[indexPath.Row].Id,nav); nav.PushViewController(c,true); tableView.DeselectRow(indexPath,true); } public ListDelegate(UINavigationController nav) { this.nav = nav; } } public class ListDataSource:UITableViewDataSource { bool toggle=true; Dictionary<string,UIImage> images = new Dictionary<string, UIImage>(); public List<MyDeal> deals = new List<MyDeal>(); Dictionary<int,ListCellViewController> controllers = new Dictionary<int, ListCellViewController>(); public ListDataSource(List<MyDeal> deals) { this.deals = deals; } public override int RowsInSection (UITableView tableview, int section) { return deals.Count; } public override UITableViewCell GetCell (UITableView tableView, MonoTouch.Foundation.NSIndexPath indexPath) { UITableViewCell cell = tableView.DequeueReusableCell("cell"); ListCellViewController cellController = null; if (cell == null || !controllers.ContainsKey(cell.Tag)) { cellController = new ListCellViewController(); NSBundle.MainBundle.LoadNib("ListCellViewController", cellController, null); cell = cellController.Cell; cell.Tag = Environment.TickCount; controllers.Add(cell.Tag, cellController); } else { cellController = controllers[cell.Tag]; } if (toggle) { cell.BackgroundView = new UIImageView(UIImage.FromFile("images/bg1.jpg")); } else { cell.BackgroundView = new UIImageView(UIImage.FromFile("images/bg2.jpg")); } toggle = !toggle; MyDeal d = deals[indexPath.Row]; cellController.SetValues(d.Title,d.Price,d.Value,d.DiscountPercent); GetImage(cellController.Thumbnail,d.Thumbnail); return cell; } private void GetImage(UIImageView img, string url) { img.Alpha = 0; if (url != string.Empty) { if (images.ContainsKey(url)) { img.Image = images[url]; img.Alpha = 1; } else { var context = TaskScheduler.FromCurrentSynchronizationContext (); Task.Factory.StartNew (() => { NSData imageData = NSData.FromUrl(new NSUrl(url)); var uimg = UIImage.LoadFromData(imageData); images.Add(url,uimg); return uimg; }).ContinueWith (t => { InvokeOnMainThread(()=>{ img.Image = t.Result; RefreshImage(img); }); }, context); } } } private void RefreshImage(UIImageView img) { UIView.BeginAnimations("imageThumbnailTransitionIn"); UIView.SetAnimationDuration(0.5f); img.Alpha = 1.0f; UIView.CommitAnimations(); } } } Here is the ListCellViewController, that contains a custom cell using System; using System.Collections.Generic; using System.Linq; using MonoTouch.Foundation; using MonoTouch.UIKit; { public partial class ListCellViewController : UIViewController { #region Constructors // The IntPtr and initWithCoder constructors are required for items that need // to be able to be created from a xib rather than from managed code public ListCellViewController (IntPtr handle) : base(handle) { Initialize (); } [Export("initWithCoder:")] public ListCellViewController (NSCoder coder) : base(coder) { Initialize (); } public ListCellViewController () : base("ListCellViewController", null) { Initialize (); } void Initialize () { } public UIImageView Thumbnail { get{return thumbnailView;} } public UITableViewCell Cell { get {return cell;} } public void SetValues(string title,decimal price,decimal valuex,decimal discount,int purchases) { } #endregion } } All help is greatly appreciated

  • MonoTouch & SQLite - Cannot open database after previous successful connections

    - by Tanis Draven
    I am having difficulty in reading data from my SQLite database from MonoTouch. I can read and write without any difficulty for the first few screens and then suddenly I am unable to create any further connections with the error: Mono.Data.Sqlite.SqliteException: Unable to open the database file at Mono.Data.Sqlite.SQLite3.Open (System.String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool) [0x0007e] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLite3.cs:136 at Mono.Data.Sqlite.SqliteConnection.Open () [0x002aa] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLiteConnection.cs:888 I ensure that i dispose and close every connection each time i use it but still i have this problem. For example: var mySqlConn = new SqliteConnection(GlobalVars.connectionString); mySqlConn.Open(); SqliteCommand mySqlCommand = new SqliteCommand(SQL, mySqlConn); mySqlCommand.ExecuteNonQuery(); mySqlConn.Close(); mySqlCommand.Dispose(); mySqlConn.Dispose(); I'm guessing that I'm not closing the connections correctly. Any help would be greatly appreciated.

  • jQuery-ui problem with modal dialog from ajax

    - by Intra
    Hi I have following setup index.html with <div id="container"</div using anchor method I load different html content into this container. My content contains div for modal dialog "dialog-form" and I initialise it with the custom function from the javascript included in index.html on successful ajax load using callback $.get("callback.php",query, function(data){ $("#container").html(data); initPos(); // here we run javascript to initialise modal dialog }); Everything is ok until user click other menu (we load different content) and after that again clicks menu with this modal dialog, so page loads again, we call script again (everything is ok yet), dialog opens, information from the dialog is submitted to server and on sucessful sumbit I want to close the dialog with ('#dialog-form').dialog('close');it worked first time, but no longer works because we initialised this dialog twice and using Firebug I can see two different instances of modal dialog with the same name. So, what is the right way to do the thing? Is there any way to close multiple dialogs with the same name or maybe we can kill all closed modal dialogs when user clicks different menu?

  • handling NSStream events when using EASession in MonoTouch

    - by scotru
    Does anyone have an example of how to handle read and write NSStream events in Monotouch when working with accessories via EASession? It looks like there isn't a strongly typed delegate for this and I'm having trouble figuring out what selectors I need to handle on the delegates of my InputStream and OutputStream and what I actually need to do with each selector in order to properly fill and empty the buffers belonging to the EASession object. Basically, I'm trying to port Apple's EADemo app to Monotouch right now. Here's the Objective-C source that I think is relevant to this problem: / / asynchronous NSStream handleEvent method - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch (eventCode) { case NSStreamEventNone: break; case NSStreamEventOpenCompleted: break; case NSStreamEventHasBytesAvailable: [self _readData]; break; case NSStreamEventHasSpaceAvailable: [self _writeData]; break; case NSStreamEventErrorOccurred: break; case NSStreamEventEndEncountered: break; default: break; } } / low level write method - write data to the accessory while there is space available and data to write - (void)_writeData { while (([[_session outputStream] hasSpaceAvailable]) && ([_writeData length] > 0)) { NSInteger bytesWritten = [[_session outputStream] write:[_writeData bytes] maxLength:[_writeData length]]; if (bytesWritten == -1) { NSLog(@"write error"); break; } else if (bytesWritten > 0) { [_writeData replaceBytesInRange:NSMakeRange(0, bytesWritten) withBytes:NULL length:0]; } } } // low level read method - read data while there is data and space available in the input buffer - (void)_readData { #define EAD_INPUT_BUFFER_SIZE 128 uint8_t buf[EAD_INPUT_BUFFER_SIZE]; while ([[_session inputStream] hasBytesAvailable]) { NSInteger bytesRead = [[_session inputStream] read:buf maxLength:EAD_INPUT_BUFFER_SIZE]; if (_readData == nil) { _readData = [[NSMutableData alloc] init]; } [_readData appendBytes:(void *)buf length:bytesRead]; //NSLog(@"read %d bytes from input stream", bytesRead); } [[NSNotificationCenter defaultCenter] postNotificationName:EADSessionDataReceivedNotification object:self userInfo:nil]; } I'd also appreciate any architectural recommendations on how to best implement this in monotouch. For example, in the Objective C implementation these functions are not contained in any class--but in Monotouch would it make sense to make them members of my

  • MonoTouch Hello World for iPad

    - by Bryan
    I have tried following the sample Hello World for MonoTouch by creating an iPad solution. For some reason I cannot get the MainWindow to load. I followed the instructions exactly and the app just closes before even loading a view. Is there something missing? Do I need to tell the solution how to load the MainWindow.XIB or something? Please help, this seems very basic and I am about to throw MonoTouch in the garbage.
