Where should I start?

Question

Hey all,

I'm an amateur programmer. I know a decent amount of PHP and a tidbit of JavaScript.

I'm looking to learn some C# at the moment. In fact, I'm hoping to make a specific program but the problem is I don't know where to start.

I want to make a very simple program. All it does is show a custom screen on startup of the computer and have an icon in the taskbar. The only thing I want it to do right now is to have a password prompt appear if the icon is right clicked or if the programs exe is activated.

I assure you I am not trying to get someone to do this for me or to have the answers handed to me on a silver platter. I just want to know how and where I would start learning this.

Thanks guys!

Answer 1

what is the access modifier of your GetProducts() method? Make sure it's public and not protected.

Answer 2

I re did it. All is ok but it shows error for GridView1.DataSource = productsAdapter.GetProducts();

 

It says GetProducts () is not accessible. I have added the method GetProducts () in TypedDataset but it doesn't work.

Answer 3

You may need to recreate your web form again and grab a new GridView control from the toolbox. This could sometimes happen if you directly copy and pasted codes/html in your code behind in which the designer cannot register the controls for you. 

 

So try generate back your page and then step back through the article you referred. 

Answer 4

Yes I did use the ID GridView1 in aspx.cs but still it's showing the same error . Also I did what u suggested but now the method GetProducts() shows error and says it is not accessible due to protection level.

Answer 5

In the first error make sure that you have a GridView control in your ASPX.CS file with ID "GridView1"

 

In your second error make sure that you declare the namespace where the ProductTableAdapter class was defined. Or simply use the fully qualified name like NameSpaceName.ProductTableAdapater

Answer 6

Thank you for answering. The errors are:

 

The name GridView1 doesn't contain in the current context. And ProductTableAdapter is missing a namespace.

Answer 7

What's the actual error you get?

 

Typed DataSets are kinda obsolete and since you are new to ASP.NET I would suggest you to take a look at Entity Framework instead as your Data Access mechanism.

And if I may add. Start learning MVC instead of WebForms :)
