Hi Mariyan, I just started this course couple of days ago, coming from Python, I found it informative and motivating, The current situation is that I've faced lots of errors on my first building, although I followed your script (at least according to my knowledge). I am using Visual Studio 2022. Can you please guide to go on easily through the rest of the cours? Will list below some of the errors. Thanks in advance. Error CS0535 'Main' does not implement interface member 'IExternalCommand.Execute(ExternalCommandData, ref string, ElementSet)' Revit_Test C:\Users\XDH\source epos\Revit Test\Revit Test\Main.cs 14 Active Error CS0118 'UIApplication' is a type but is used like a variable Revit_Test C:\Users\XDH\source epos\Revit Test\Revit Test\Main.cs 19 Active Error CS0118 'UIApplication' is a type but is used like a variable Revit_Test C:\Users\XDH\source epos\Revit Test\Revit Test\Main.cs 19 Active Error CS0818 Implicitly-typed variables must be initialized Revit_Test C:\Users\XDH\source epos\Revit Test\Revit Test\Main.cs 19 Active

How did you created SimpleForm Console? I could not find in videos

[@mariyandeveloper8437]

It was done at the very beginning of tutorials. The video is called: Revit API Course for beginners | Lesson 3 | Element Selection 3:22

[@GiorgiBekurashvili]

​@@mariyandeveloper8437 Thank you very much! I am very thankful for your tutorials! And now i will reach out to you by mail. I'm interested in C# Revit API deeper

[@YingCai-r8k]

Hi, is there an alternative for SimpleForm() and .ShowDialog()? When I run the code on my end, it pops error with no module founded. Thank you.

[@daichi_devs]

Right click on References > Add Reference > click on Assemblies on the left column > scroll down to System.Windows.Forms and click checkmark > press ok. Go to the SimpleForm script and at the very top add using System.Windows.Forms; save.

@@daichi_devsI have the same problem and your solutions doesn’t work any other idea ?

[@camilyvasconcelos8231]

hey. Thanks for the video. I'm using visual studio 2022 and I can't find "User Control WPF". I think that dont exists anymore. Is it possible that the User Control WPF has been replaced by the Inherited User Control (Windows Forms)? Is Inherited User Control (Windows Forms) same as User Control WPF?

[@mariyandeveloper8437]

Hey, User Controls have not been replaced or removed in Visual Studio. It's different from Windows Forms. "User Control WPF" refers to a control used in the WPF framework, which is based on XAML for its UI design and offers more advanced graphics and layout capabilities. o have User Control you need to include it. You can either select the the template that includes all of the required libraries for it or setup it yourself. The project template is called "WPF Class Library". Or you can open csproj file, Inside the tag, add the line true. This tells the project to include WPF-specific build actions and references. Even with UseWPF set to true, you might need to add specific references to WPF libraries if they are not automatically included. These typically include PresentationFramework, PresentationCore, and WindowsBase. Hope that helps!

[@camilyvasconcelos8231]

Thank you for your help. I managed to fix this. I need to install an online template "Catel-WPF-UserControl". After that I can use User Control (WPF).@@mariyandeveloper8437

Hi Mariyan. Could you help me.. How should i define the ExternalCommand setup with your variables!!. Can I get your sourcecode somewhere.. Github mayby ?

Hey, I haven't pushed it to GitHub. But could you tell me, please, what variables you are talking about?

Hi! i am following the tutorial and making sure all my text matches but im on 4:02 into the video and gives me multiple errors (CS0723 / CS0029 / CS0122) =/

Hey!) Could u send a screenshot?

[@dennishopper1388]

I cannot get this one to run? Assembly missing?

[@mariyandeveloper8437]

How could I know? The compiler should tell you the problem.

[@dennishopper1388]

@@mariyandeveloper8437 I’m sorry, I thought I copy pasted the error message. I will try again later. I’m looking for the answer to what the message means. I’m in my infancy with this language and so I’m not positive on what to search for to find a resolution.

[@dennishopper1388]

Failed to initialize the add in "Multi Cat Filter" because the class "Multi Cat Filter Command 1"cannot be found in the add in Assembly. The full classname provides the entry point for Revit to call the add in application. For Revit to run the add in, you must ensure this class implements the Autodesk.Revit.UI.I.ExternalCommand interface.
