Hi Peter, I thought you'd gotten fed up with me pestering you Big Grin | :-D

That sounds a very neat way of deploying it - I didn't realise Jenkins works on a Linux box I've only ever used it for building nuget packages I'll check it out - thanks again

How to read .dbc file in C#?

Please help me...

For those that don't know, .dbc files are Visual FoxPro files. With that knowledge, we should be able to guess that you need to perform SQL queries against this, so there is probably some form of .NET database connector. Fortunately, there is - you need to download Microsoft OLEDB for Visual FoxPro; search in Google for VFPOLEDB. See here[^] for details of how to format your connection string. Beyond that, it's now up to you.

I was actually just about to jump on Twitter and ask you if this was a foxpro related thing Smile | :)

I sort of recognized the extension name, but it's been a long time since I even saw one in the wild.

Then I noticed your reply...

A .DBC is a "data dictionary" (of sorts) in .DBF format. Use a Visual FoxPro ODBC driver. Not essential to using the files it points to outside the "app" the .DBC relates to.

You could even import it into SQL Server, if that's easier. (Or Excel, Access).

You can access FoxPro DBC/DBF from .Net app using ADO.net and the VFP Oledb driver.

I found this in another post that may help you:

You can use the FoxPro and Visual FoxPro OLE DB data provider to access your DBFs. A typical connection string for FoxPro "free" tables is "Provider=VFPOLEDB.1;Data Source=C:\Temp\;" In your SQL statements you would refer to the specific DBF you are selecting data from. If there is a DBC (Database Container) file present where the DBFs are, then point your connection string to it, and again, refer to specific tables in your SQL commands. For example, "Provider=VFPOLEDB.1;Data Source=C:\Temp\Test.dbc;"

I need to develop app that recognizes and tracks a specific object once it's in the Web Cam's fields of view. I found this, which is sort of what I want. That app seems to identify speific colors, then track those colors even when the object is moved.

What I need to is identify a specific object, probably by some identify feature(s), and then track it the whole time it's in the camera's field of view. I'm using a wide angle web cam with a 120 degress FOV.

Anyone have any experience with this? Any ideas on how to get started?

Thanks

Simplistically speaking, object tracking can be thought of as object detection over a number of frames, with each frame being represented as a stream. What you really need is a good object detection implementation, something like GitHub - AlturosDestinations/Alturos.Yolo: C# Yolo Darknet Wrapper (real-time object detection)[^]. Obviously, you will want to go with the GPU approach, with that being far faster than you could get with the CPU implementation.

Thanks Pete, I'll take a look

Have you used this Alturos.Yolo before? It looks really promising, but as soon as I stat the app I get

Cannot found a valid dataset System.IO.FileNotFoundException: Cannot found pre-trained model, check all config files available (.cfg, .weights, .names)

   at Alturos.Yolo.YoloConfigurationDetector.Detect(String path)

   at Alturos.Yolo.TestUI.Main.Initialize(String path) in C:\Projects\Alturos.Yolo\Alturos.Yolo-master\src\Alturos.Yolo.TestUI\Main.cs:line 255

I'm guessing there's some kind of configuration that I need to do, but there isn't much documentation that I can see

Object detection is an ML technique that uses pre trained models to identify objects. You need to download the trained models.

I have tried many things before I found costura.fody and I were hoping that would be the solution to create a single file exe of a cefsharp application that I'm doing.

So the help file for costura.fody says to set the copy local to true of the file you want to embed in the solution explorer. Done that.

So the exe got a little bit bigger when I did that but I notice that the size was not even close to cover libcef.dll so I suspected that this file was not embedded.

I tested this by renaming the dll in the output folder and yes I couldn't run the application.

I would really love for this to work but I'm kind of giving up. I was struggling with AppDomain.CurrentDomain.AssemblyResolve to tap into that event but it was never called. Even when defining it in the static constructor to make sure it is started before anything else.
I'm currently using this code:

C#

[STAThread]
public static void Main(string[] args)
{
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(ResolveAssembly);
}

Just to clarify things, I'm using a windows forms project and I'm trying to make it as close to the examples I can find online. I would prefer to just add it in the Form1 constructor.
It should be calling this function

C#

private static Assembly ResolveAssembly(object sender, ResolveEventArgs args)
{
    throw new NotImplementedException();
}

But it never does.

In the .csproj file tried this snippet.

<Target Name="Prebuild">
   <CallTarget Targets="Clean" />
   <MSBuild Projects="$(SolutionPath)" Targets="Build" Properties="Configuration=Debug;IgnoreRecursion=true" />
 </Target>
 <Target Name="BeforeBuild">
   <ItemGroup>
     <_IgnoreRecursion Include="$(IgnoreRecursion)"/>
   </ItemGroup>
   <CallTarget Targets="Prebuild" Condition="'%(_IgnoreRecursion.Identity)' != 'true'" />
   <CreateItem Include="$(TargetDir)\**\*.*">
     <Output TaskParameter="Include" ItemName="OutputFiles" />
   </CreateItem>
   <ItemGroup>
     <EmbeddedResource Include="@(OutputFiles)" Condition="('%(OutputFiles.Extension)' == '.dll' Or '%(OutputFiles.Extension)' == '.pdb')">
       <LogicalName>%(OutputFiles.DestinationSubDirectory)%(OutputFiles.Filename)%(OutputFiles.Extension)</LogicalName>
     </EmbeddedResource>
   </ItemGroup>
   <Message Importance="high" Text="Embedding: @(OutputFiles->'%(Filename)%(Extension)', ', ')" />
 </Target>

This embeds the dll's fine. I just wish ResolveAssembly could be called. If it was I could have this code taking care of the lost dll's

//static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
//{
//    return null;
//    //var currentAssembly = Assembly.GetExecutingAssembly();
//    //var requiredDllName = $"{(new AssemblyName(args.Name)).Name}.dll";
//    //var resource = currentAssembly.GetManifestResourceNames().Where(s => s.EndsWith(requiredDllName)).FirstOrDefault();
//    //if (resource != null)
//    //{
//    //    using (var stream = currentAssembly.GetManifestResourceStream(resource))
//    //    {
//    //        if (stream == null)
//    //        {
//    //            return null;
//    //        }
//    //        var block = new byte[stream.Length];
//    //        stream.Read(block, 0, block.Length);
//    //        return Assembly.Load(block);
//    //    }
//    //}
//    //else
//    //{
//    //    return null;
//    //}
//}

Can anyone please help me with this?

Kind regards andla

See AppDomain.AssemblyResolve Event (System) | Microsoft Docs[^] which includes a complete detailed sample.

I'm sorry this doesn't help me.
The resolve event should be triggered automatically when a dll is missing.
It doesn't trigger at all.

It is triggered automatically, on every assembly load.

The question is did you wire up the event correctly in your code?

I can't find any true answer to that only answers that have worked for other people with other setups different from mine.
So I have tried various solutions that have worked for others but it doesn't work for me.

Question is it possible that it is not triggered by recursive loads?
I mean if one dll that I see in the project needs another dll that is missing maybe then the resolve function is not triggered?

I mean in my cefsharp project (embedded chrome for c#) I have one dll named:

libcef.dll

This dll is not visible in the reference section but the application needs it anyway.
Costura.Fody doesn't embed this dll.

I did another test:
I renamed

CefSharp.Core.dll

to something else.
This dll is listed in the references.
The resolve function was successfully triggered.

Okay, so the question is, how do I embed everything and create one stand-alone exe?
How can I embed all resources not only the dll's but everything needed in the exe?
This is what I originally wanted.

You can only embed .NET .DLL's. If it's a C/C++ library .DLL, it cannot be embedded into the executable.

The library .DLL's are not loaded through the .NET CLR binding mechanism, so they will not have a binding event triggered for them.

I now have a net core api service up and running on a Linux box using Nginx as a reverse proxy server, I can call all of the controller methods that don't have parameters and they return collections of my custom classes. But I'm stuck on one get method that requires a custom class as an input parameter, the controller method code is below

[HttpGet]
[ActionName("GetBOM")]
public ActionResult<bomparam> GetBOM([FromBody] BOMParam bp)
{
// This calls my DAL which queries a database and returns the bp populated with various values
return businessLayer.APIGetBOM(bp);
}

What I can't figure out is how to pass a class instance as a parameter to the method using RestSharp

This is what I've tried
Hide Copy Code

RestClient client = new RestClient("http://IPOfRestService:Port/GetBOM");
RestRequest request = new RestRequest(Method.GET);
BOMParam bp = new BOMParam();
bp.ValveCode = "80044-08";
bp.Torque = 20;
bp.DirectFit = false;
bp.BarPressure = 6;
request.AddJsonBody(bp);
IRestResponse response = client.Execute(request);

I get a not found back in the response object.
Can't find anything googling so thought I'd try here

Hi Gerry, I followed that link and the only thing the guy was doing differently to me was issuing a Post whereas mine is a Get - apparently it's frowned upon to add a body to a Get request , so I modified my Controller and it worked - it's not returning what I expect but that's probably anther story - thanks for the heads up

Edit

Using the RestSharp deserializer doesn't map the property names that are in different case though , JsonSoft does
