I am new to blazor and I've chosen to learn blazorserver but whenever i create a project, it comes along shipped with a lot of stuff i don't need. I don't need the layout it offers. I want to build my own layout from scratch. I also want to get rid of bootstrap and replace it with tailwind. The problem is that there are a lot of files and directories that make me fear to break the app. Is there a kinda command that can generate a much cleaner project or some way of manually cleaning it app without breaking the app. I appreciate any help.
If you are afraid of breaking the app by deleting something then it's better to keep it. You already figured out that you can replace bootstrap library with tailwind and that you can replace the layout with your own. While developing on the project you will start understanding what is the purpose of each folder or file in the starter template. After you understand their purpose, you will be able to decide if you need them or not.
Also learning how to use version control (e.g. git), like #JHBonarius mentioned, is very good advice. So when you break something you can easily revert back to previous working version of code.

I'm working on a project and I'm fairly new to ASP (not to C#).
We have a solution for a whole web application consisting of several projects and I want to add a couple of ASP WebForms to one of the projects. However, when I right click on the folder of the project and select Add element, it only shows me VB options.
But if I try to add other project to the solution, then all the other options are displayed.
The project in which I'm trying to add new Web Forms is entirely written in C#, so I don't know well what's happening back there. I cannot stop thinking it might a dumb mistake I'm making.
I'm working under Visual Studio 2017 and .NET Framework 4.7.2. It is there some kind of requirement I'm missing?
Thanks in advance for your time and sorry if it's something simpler, but I really don't know what's going on here.
As noted, this looks like that one application was created as a vb.net application.
You can freely consume say c# code (assemblies) in a vb.net project. And of course you can do the reverse.
However, for a given project created? You can't at the IDE level mix vb.net and c# code modules and general writing of code between c# and vb.net.
However, as in your example, you can certainly "include" multiple mixes of vb.net and c# projects into one same project. However, each part and section will still be limited to the chosen language used to build that application. So mixing is allowed at the project level - but not below that level.
So, it looks to be that project was created and developed with vb.net. You can't really change that unless you create a new project as c#, and then pull in all the forms, code etc. and re-factor the vb.net to c#.
So your practical project language choice is really limited to the project level. Multiple projects of different languages can be included overall, but each part will remain in its given language choice. The fact that you can do this in .net is amazing enough, but that language choice is really set in stone at the project level.
While you're figuring it out, if you need to press on and get some work done just copypaste another file that is already in the solution, and is of the type you require, then change its contents. This can usually be a time saver anyway, as the "new product" form isn't so hugely different from the "new user" form, just a different bunch of labels and textboxes..
There is nothing magical about the "add new item" dialog, it just adds files with pre filled templated content. For a cs class (for example) that's a file that basically has a detected namespace and the name you specified in the add dialog. You could even add a VB file of the type you want and then change the contents and name of the file to be right for C# - it would essentially be adding a couple of curly brackets and changing the case of Namespace and Class (and maybe changing Imports to using)
You cannot mix languages in the same assembly in .Net. Create another assembly you can put your C# code in there and use it in the VB.Net project.
Or use VB.Net it's not that bad.
I am still getting used to working with c# and wpf. I have made a number of smalls apps to do single tasks. To give the same feel to the apps my company uses I use the same logo, colours and layout.I am also developing a project settings class to save the project variables to file using a json file ( I hope ) and a slide out panel to give the user access to the project variables.
It would make sense to save this as a sort of template / base project so that every time I start a new project I can use this base project to shortcut the workload but every time I to do this I get errors. I have read about class library but am not certain if the is correct way forward or should be some sort of template.
Can someone explain if want I want to do is possible in wpf and what is the correct way forward please. Any questions on here (this site) assumed a bit too much knowledge for me and I can't get my head around the msdn references. So any good links would be helpful
Thanks
In Visual Studio, once you have the basic solution template that you want.
File->Export Tenplate.
Create a new Project Template.
Or if you just want to create a reusable theme. Create a class library and put some ResourceDictionaries inside with your styles and templates, etc. Then reference it from each new project and import the resource dictionaries. This solution would probably be easier to maintain over time as you could easily replace the referenced DLL with a new version when you make changes to the common UI theming.
I'm trying to create a wpf application such as a movies library because i would like to manage and sort out my movies with a pretty interface.
I'd like to create a library with all my movies getting information from the web, but i don't know how very well.
I thought to get the information from a web site, for example imdb, but i don't know if it's legally to capture html from page to get the nested information.
It's my first desktop application and I would also like to know if it is necessary to create a database within the project and then create a setup project with specified script for deploy it.
Sorry for the confusion but i would like to know too much things :)
Thanks a lot in advance.
The legality of web scraping is a grey area. See my question, "Legality of Web Scraping vs Normal Use" and the corresponding answers for some insight.
Even if the legality is not a problem, web scraping is a flimsy approach because the webpage structure may change without notice, making your application suddenly useless until you update it to the new format. You are much better off using some sort of web API (if the site providing the information offers it).
Whether you need a database or not depends entirely on what your application will be doing and how you design it - it's not something any of us can tell you.
Same goes for the setup project - in fact I wouldn't worry about that until you actually have a working application. Take it step by step and keep the scope within control.
Yes I did not think about api.
It's a great idea, maybe use "themoviedb".
But if i create an application based on it, that has to show all the movies that you have stored on your hdd and get , for example, the posters, the description and the ranking, i have to create a database according to you?
Thanks a lot.
I need to create a simple application that would generate reports based on database data and some user input. I have vast C/C++ experience, but for this project we had to choose C#.
I want to avoid using 3rd-party components that would require installation on a client machine as much as possible. Thus, I would like to avoid using even the features provided by MS Office (I could have used an XLS template, just like my predecessor did, but it doesn't look like a way to go; anyways, my predecessor's sources are long lost, which is probably good, since it is a roughly 10-years-old VB monstrosity that crashes every now and then). The same goes for crystal reports and whatnot.
My current idea is to build HTML tables (using an HtmlDocument) on the fly, to present them to the user (using a WebBrowser) and to print them. Is it a right way to go? Are there any simpler/more robust/better approaches? What are the possible pitfalls?
Building tables on the fly would work. I use that technique every so often, but it seems like a hack to me. I only use it because quite often, the business need requires "good enough" and quick turnaround as opposed to "beautiful".
I'm going to preference what I'm about to suggest bysaying that I have a strong bias against 3rd-party components myself.
I flat out refuse to use them in most cases and will go out of my way to come up with another solution, because I've been burned on upgrades/licensing too often.
That said...
Fortunately, with .NET not all 3rd party components need to be installed to your clients PCs. With XCOPY deployment, often you can just reference a .DLL or a project in the solution ans specify the "Copy Always" or "Copy if newer" option to just include the dll (or resulting dll if you're referencing a class library project) and as long as the .dll is present in the same directory as the executable, the 3rd party component works.
With all of that in mind, there's a project that I've used to print a DataGridView from Windows Forms at CodeProject. This is one that you can get the source for, reference it, and use it without having to actually install anything at the client. I've used it in more than one app, and it's one of my favorite tools.
It will print ONLY the DataGridView, but it prints it exactly as it appears on screen, so if that's what you want, I'd recommend at least checking it out.
As a third option, you could consider using ASP.NET. If you're going to be generating HTML, it's just as easy (easier actually) to do it using ASP.NET than in a WinForms app. Using ASP.NET you get Repeaters, ListViews, etc, all of which make the reports easy to create.
I've got more than one real-world app that is primarily a WinForms app but has an associated reporting site.
For example, I have a WinForms app used for scanning coupons accepted at our retail locaitons. It's a WInForms app because I need to interact directly with the scanner on a COM port. However, for the reporting portion, I set up an ASP.NET website. In the WinForms app it's very simple to create a reporting menu option and point to the pages. Our users generally don't even think about the fact that this is two distinct applicaitons. They see it as one - their Coupon Scanning app.
The point of all that is that it's usually possible to do things with any given tool, but it's far easier to use the tool that is meant for the job. If you're going to be generating HTML reports, ASP.NET is a better tool than building the reports manually, and if you need to have a WinForms app for most of the UI, you can still do that and use the website for the reports - using the best tool for each task.
Maybe you would like to check RazorEngine, to create your HTML templates.
I recommend you Razor engine to render html, it is more flexible than working with HtmlDocument objects.
You can create a file with your report template, and then parse it sending a Collection of your report rows objects.
This might sound a bit of an odd question but I know what I want to achieve, just don't know if it's possible.
Firstly, I'd like to be able to create a visual studio project that the 2 developers that work with me can use as a basis for all new websites. I want to drop all the common files that we use in there, like jQuery, CMS files etc. so that every time they start a new project they don't have to worry about all of that stuff. I guess to do this I just set up a project and "File > Export Template" ?
Now, here's the tricky bit...
When you open up one of the default templates in VS it asks you a few questions, such as if you want to use a master page or if you want to use code behind etc.
What I would like to do is set up something similar so that when you use the project template it asks you what version of jQuery you want to use so that it can import the right file, or for example it might ask you if you want to include certain user controls that the CMS contains. If you tick the box then the folder with the necessary user controls would be put in your new project for you.
I know MS can do this but can a user like me include functionality like that in my own project template?
Hope that makes sense.
Some more digging turned up the iWizard interface and this tutorial...
