i run the following code and instead of running the package exe (just some command line stuff wrote in .NET) i notice another instance of the existing app
does anyone had this and know how to solve it?

BTW, i printed out the package exe path and it looks OK but still there's a process with the same app name instead of the exec

   if (string.IsNullOrEmpty(package_exe_path))
            return true;

   Console.WriteLine(package_exe_path);

        var psi = new ProcessStartInfo
        {
            FileName = package_exe_path,
            Arguments = arguments,
            UseShellExecute = false,
            CreateNoWindow = true,
            ErrorDialog = false
        };

        try
        {
            var p = Process.Start(psi);

            if (p == null)  
            {

                return false;
            }
        }

Hi,

We currently have an IOS and Xamarin.MAC shared code application based on Xamarin.IOS and Xamarin.MAC.

it works very well.

We would like to port the application on Windows. Is there a tool for transforming XIB Files into WinForms (WPF, XAML, ...)?

Where to do that, should I redo as I did for Xamarin.MAC all screens in a Windows project?

Thanks for your help.

Hi All,
I'm running into a few exceptions related to System.ServiceModel.Web. According to the documentation, this is an available assembly, but I get errors whenever I try to work with it from my Xamarin.Mac app.

Simply running this code:

            var Data = System.IO.File.ReadAllBytes(@"/Library/Frameworks/Mono.framework/Versions/5.8.0/lib/mono/4.6.1-api/System.ServiceModel.Web.dll");

            System.Reflection.Assembly.Load(Data);

Generates the exception.

Does anyone have any suggestions? Perhaps something is messed up with this assembly?

Hello,

I was working through this tutorial https://developer.xamarin.com/guides/mac/user-interface/working-with-collection-views and was unable to get it to work. I was getting the following runtime error: "-[NSNib _initWithNibNamed:bundle:options:] could not load the nibName: EmployeeItemController in bundle (null)."

I got it working eventually, and I believe the problem was the following part of the instructions. In "Creating the Cell Prototype" we are directed to create a new ViewController with the name EmployeeItem, and we're told that "This will add an EmployeeItem.cs, EmployeeItemController.cs and EmployeeItemController.xib file to the project's solution." That is not true: what you get are the three files EmployeeItem.cs, EmployeeItemController.cs and, crucially, EmployeeItem.xib. You must manually rename the .xib file to be EmployeeItemController.xib.

Hopefully this helps others.

Hi there, I'm an experienced c# developer porting an app to the Mac/iOS although I'm very new to writing anything for an Apple environment so it's a massive learning curve finding out how it all hangs together. I have successfully used the storyboard to get a TableView populated with my data and displaying. However I've got about 20-30 of these tableview to add and it seemed pointless to manually configure them all when they are all the same general idea just different interfaces describing the display fields from different classes.

So instead of using storyboards I want to create my viewcontroller/tablesource programatically and once it's working for a test case I can eventually move on to using a generic class to create a controller/tablesource. NB. I'm using a tablesource in order to make the code differences between a MacOS version and an iOS version minimal.

My issue is that when I create a table column it's not got a TableCellView and try as I might I cannot find a way of programmatically adding an NSTableCellView (standard or customised) to my columns. Here is my code.

ViewController:

using System;
using Foundation;
using AppKit;
using FTAnalyzer.Mac.DataSources;
using System.Reflection;

namespace FTAnalyzer.Mac
{
    public partial class IndividualsViewController : NSViewController
    {
        FamilyTree _familyTree;
        NSTableView _individualsTableView;

        public IndividualsViewController(IntPtr handle) : base(handle)
        {
            _familyTree = FamilyTree.Instance;
        }

        public void ResetDocument()
        {
            if (!NSThread.IsMain)
            {
                InvokeOnMainThread(() => ResetDocument());
                return;
            }

            _individualsTableView = new NSTableView()
            {
                RowSizeStyle = NSTableViewRowSizeStyle.Default,
                Enabled = true,
                UsesAlternatingRowBackgroundColors = true,
                ColumnAutoresizingStyle = NSTableViewColumnAutoresizingStyle.Sequential,
                Source = new IndividualsTableSource()
            };

            PropertyInfo[] properties = typeof(IDisplayIndividual).GetProperties();
            foreach (PropertyInfo property in properties)
            {
                var tableColumn = new NSTableColumn()
                {
                    Identifier = property.Name,
                    Width = 100,
                    Editable = false,
                    Hidden = false,
                    Title = property.Name
                };
                _individualsTableView.AddColumn(tableColumn);
            }
        }

        public override void LoadView()
        {
            base.LoadView();

            ResetDocument();
            _individualsTableView.ReloadData();

            var scrollView = new NSScrollView()
            {
                DocumentView = _individualsTableView
            };
            View = scrollView;
        }
    }
}

TableSource:

using System;
using Foundation;
using AppKit;
using FTAnalyzer.Mac.DataSources;
using System.Reflection;

namespace FTAnalyzer.Mac
{
    public partial class IndividualsViewController : NSViewController
    {
        FamilyTree _familyTree;
        NSTableView _individualsTableView;

        public IndividualsViewController(IntPtr handle) : base(handle)
        {
            _familyTree = FamilyTree.Instance;
        }

        public void ResetDocument()
        {
            if (!NSThread.IsMain)
            {
                InvokeOnMainThread(() => ResetDocument());
                return;
            }

            _individualsTableView = new NSTableView()
            {
                RowSizeStyle = NSTableViewRowSizeStyle.Default,
                Enabled = true,
                UsesAlternatingRowBackgroundColors = true,
                ColumnAutoresizingStyle = NSTableViewColumnAutoresizingStyle.Sequential,
                Source = new IndividualsTableSource()
            };

            PropertyInfo[] properties = typeof(IDisplayIndividual).GetProperties();
            foreach (PropertyInfo property in properties)
            {
                var tableColumn = new NSTableColumn()
                {
                    Identifier = property.Name,
                    Width = 100,
                    Editable = false,
                    Hidden = false,
                    Title = property.Name
                };
                _individualsTableView.AddColumn(tableColumn);
            }
        }

        public override void LoadView()
        {
            base.LoadView();

            ResetDocument();
            _individualsTableView.ReloadData();

            var scrollView = new NSScrollView()
            {
                DocumentView = _individualsTableView
            };
            View = scrollView;
        }
    }
}

I think this has more to do with Mono, but I'll still ask. How does Mono/Xamarin symbolicate its crash reports?

With PLCrashReporter I get something like this:

While there is a method to symbolicate the symbols at runtime in PLCrashReporter, their documentation seems to deter us from using it.

Is there any better way to do it with Xamarin?

Please see the corresponding "Release: 15.6" post on the Release Blog for the details about this release.

I have bug I wish to report,

After updating to todays release I can no longer run my application as it has been invalid signed, Just tried on another machine and worked before upgrading todays release, once updated I ran it again and I get the following.

Where do issue a bug to now, I think i saw that Issues to be place on Github correct ? Xamarin BugZilla ? Mono Git Hub ? Xamarin Git Hub ?

/Users/davidlilley/code/SomeProject /XXX/XXXX.csproj (Build) ->
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Mac/Xamarin.Mac.Common.targets (_CompileEntitlements target) ->

I am trying to add a subview to a view by calling the AddSubview method on view. Since I want the View's and Subviews' background to be of custom colour, I customised their appearance by setting WantsLayer to true and changing the Layer.BackgroundColor property. It works fine - the subview gets added to the view with the desired background. But I am having strange issues as I am seeing blocks around the elements -

As you can see, I can see blocks of black colour around Progress Indicator and Loading label. I can even see a block of View's label (top left) - that is actually behind the subview. I guess the issue is because of the layer enabling.

P.S.: I know this is not a Xamarin.Mac specific question, but I have searched a lot about this issue and still not able to find anything. Posting here hoping that I would get to know what the issue could be. The app is a macOS menu bar app. The subview is loaded from a .xib file.

Hi, I want to get crash reports for unhandled exception in my xamarin mac application like hockey app used for tracking exceptions for android and ios apps. I have search a lot but not get any apps for tracking unhandled exception. Please suggest any app for tracking exceptions in xamarin.mac. Thanks in advance.

Hi Everyone

I'm trying to use NSCollectionView from my .xib file not from storyboard. Its throwing some error when I'm trying to register the class for the collection view

collectionView.RegisterClassForItem(typeof(EmployeeItemController), "EmployeeCell");

Can anyone please guide me to achieve this.

Thanks

Hi everyone, I have a list of data in NsTableView. My requirement is need to disable vertical scrolling of the table view. I have gone through many suggestions but not luck. Please suggest any idea. Thanks in advance.

Hello,

I just updated to Xamarin.Mac 7.4, and I am now seeing a linker error when trying to build my project:

Process exited with code 1, command:
xcrun -sdk macosx clang -g -mmacosx-version-min=10.11 -arch x86_64 -fobjc-runtime=macosx -ObjC ...
ld: framework not found MetalPerformanceShaders
clang : error : linker command failed with exit code 1 (use -v to see invocation)

I didn't add MetalPerformanceShaders (nor do I need it). I am developing on macOS 10.11.6, and (as you see) targeting minimum macOS version 10.11 as well.

Any ideas on how to fix this?

i have NSscrollview but the scroll bar dont appear. the width of the label remains same regardless of its content. how to make the width of the label change according to its content and enable scrolling for the view. any help would be greatly appreciated.

Can somebody show me how to load a bundled image resource into a WebKit.WebView? The image resides in the Resources folder and is set as BundleResource/Do not copy? I'm trying to LoadHtmlString(), but I can't seem to get the "<img src=..." reference correct. At least I think this is the problem I'm having. I've tried both of these for the src, but to no avail.

        string filePath = "Resources/ready.png"; // remember case-sensitive
        string localGifPath = Path.Combine(NSBundle.MainBundle.BundlePath, filePath);

Actually, I'm doing this to display an animated GIF because the GIF does not animate as the Image property in an NSImage object. Is the WebView the only way to do this, assuming the WebView even works? If tire's a better way, please let me know.

Thanks

I don't know how to translate this code in xamarin, I can't find the API..

If I am looking for the IDB Agent on macOS v10.13.3, what is it official system name and where would I search to see if it installed and running?

Cross posted from Stack Overflow for greater visibility...

I'm trying to use a custom build of sqlite with MonoMac, effectively as per this question.

However, using dllmap doesn't seem to be working.

My custom dylib is being deployed into [myapp.app]/Contents/Frameworks/mycustomlib.dylib

Output of otool -L mycustomlib.dylib looks correct:

@executable_path/../Frameworks/mycustomlib.dylib (compatibility version 0.0.0, current version 0.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

My myapp.exe.config file looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <dllmap dll="sqlite3" target="@executable_path/../Frameworks/mycustomlib.dylib" os="!windows" />
</configuration>

And I have verified that it is being copied alongside myapp.exe in [MyApp.app]/Contents/MonoBundle.

I can force this to work by recompiling Mono.Data.Sqlite and directly replacing the reference to sqlite3 with mycustomlib. However, the dllmap route is much nicer.

What am I missing? How can I debug this?

TL,DR Does dllmap work on Xamarin.Mac? How can I debug it?

When I build my MacOS application, with the mmp arguments --registrar:dynamic, it shows for less than a second the mainscreen, then it crashes.

Without that arguments, my solution failed to compile with the following errors:

In c# winform case,
event add code like below

button.click += functionName;
textField.textChanged += functionName;
button.mouseOver +=functionName;

but, I can't find in xamarin mac.

I know It use overrride event on nsview, nswindow .
but there are no howto on NSControls .

I want to add like this,

button.mouseOver, button.mouseLeave, 
textBox.textChanged, textBox.enabled, textBox.disabled.... 

Please let me know, how can I create event in programmatically.
