How to distribute VisualStyles for dialogs Vista style - FIXED!

I created a self-contained package and it works. Problem is that in my project C# WinForms, I use System.Windows.Forms.VisualStyles to have dialogs in Vista style, but the sytle is not applied as if I used normal dialogs. What should I distribute to make it work? Note that the software works as expected if executed from Debug folder or from the IDE itself, but not from the Release folder after the self-contained packags is created....

How can I use wpf with c++?

Someone got some harebrained idea to develop a c++ application with a GUI, so I thought of how WPF allows you to develop in C++ (which it then translates into C#, if memory serves me right). I found this documentation page: https://learn.microsoft.com/en-us/dotnet/desktop/wpf/advanced/wpf-and-win32-interoperation?view=netframeworkdesktop-4.8 Which presents several ways to connect a C++ application to WPF in the section called "WPF Interoperation Projects", I would like a recommendation on which is the simplest, considering that this will be a simple app and I don't have experience coding C++ for a WPF application. And also some help on how to implement it (later, not now)....

Error: The value of shadow key property 'ResourceDemandChunks.Id' is unknown when attempting to save

Hey everyone! I'm stuck with this problem: The value of shadow key property 'ResourceDemandChunks.Id' is unknown when attempting to save changes. This is because shadow property values cannot be preserved when the entity is not being tracked. Consider adding the property to the entity's .NET type this is how I register entity in db context: ``` modelBuilder.Entity<WorkingTaskEntity>().OwnsOne(c => c.CustomData, t => ...

When I select a category from a picker, I want only its children to appear in the other picker

I have 3 pickers and in these pickers I have parent, child and subchild categories respectively. When I select the parent category, I want only the children of that parent to appear in the other picker as an option.However, when I select the parent category, the second picker appears empty. When I remove the Parent Category, my normal child categories appear.

Does Visual Studio come with IIS Express

Hello, Just wondering if IIS Express came with Visual Studio. I'm not quite sure what this is, but after some research I think this may have came bundled with VS and is some website hosting stuff? Also does this cause a "My Web Sites" folder to be created in documents containing all sorts of files? It was created the same time as IIS Express folder....

✅ Strange colleague

Hello, there's a colleague in my company who behaves oddly. I enjoy simplifying processes and finding better solutions for repetitive code. I implemented some patterns that reduced the workload and cleaned up messy code. And after that he starts play envy because seniors speaks high about me. But I found out this days he often reworks my solutions in regular code part in very vague solution. Instead of discussing his changes, he just pushes them without explanation, and his modifications often make the code more bug-prone. We don't have much competition in the company since we work in a niche area. His programming skills are questionable, but he understands the overall process better than I do. Despite my efforts to collaborate and be a team player, he constantly tries to assert dominance, making me feel inferior. ...
