I have tried this:
<Window.Resources>
<Style x:Key="Foo">
<Setter Property="TextElement.FontFamily" Value="pack://application:,,,/Main;component/Fonts/#MyFont" />
</Style>
<Style x:Key="Bar">
<Setter Property="TextElement.FontFamily" Value="./Fonts/#MyFont" />
</Style>
<FontFamily x:Key="Baz">./Fonts/#MyFont</FontFamily>
</Window.Resources>
<StackPanel Orientation="Vertical">
<TextBlock Text="" Style="{StaticResource Foo}" />
<TextBlock Text="" Style="{StaticResource Bar}" />
<TextBlock Text="" FontFamily="{StaticResource Baz}" />
<TextBlock FontFamily="Segoe MDL2 Assets" Text="" />
<TextBlock x:Name="txt1" />
<TextBlock x:Name="txt2" />
</StackPanel>
In the code, I have tried these different ways to set the FontFamily property. I have just listed them here. But have run them separately. All failed...
private void Window_Loaded(object sender, RoutedEventArgs e)
{
txt1.FontFamily = new FontFamily("pack://application:,,,/Main;component/Fonts/#MyFont");
txt1.FontFamily = new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#MyFont");
txt1.FontFamily = new FontFamily("MyFont");
txt1.Text = "\xe905";
} Notice the txt1.FontFamily = new FontFamily("MyFont");
I have installed the font from it's ttf-file.
If I open the Character map application in Windows I can see all symbols that I require.
I just can't understand what is going on...

I have solved it!
It was the darn TTF-file which was the problem.
When I changed to another font, the XAML-code worked straight away!

Previously when debugging my program would stop if an error occured, this no longer works.
Now I have to hunt down the error which takes hours sometimes.
Is there an option / setting I can change in order to stop on the error as it occurs.
I appreciate any help.
Thanks in advance.

Debuggers don't "stop on errors" they stop either because they hit a breakpoint you set, or an exception occurs that you aren't handling (or that is in the "break on this exception" list your project has set).
It's worth checking two things:
1) That you are actually running your app in the debugger. Yes, yes - I know that's obvious. But you'd be surprised how many people ignore the obvious ...
2) That you haven't switched exceptions off: Go to "Debug...Windows...Exception Settings" and check that "Common Language Runtime Exceptions" is a solid black.
But logic errors in your code the debugger won't automatically stop on - it has no idea what you are trying to do, so it can't! (But you knew that anyway ...)

The "break on this exception" setting overrides the unhandled part. You use it to break on exceptions which are handled in code. The debugger will always break on unhandled exceptions.

I have hundred of DataTables and many of the caption names within do not match the column name.
Is there a way I can change all captions to match column name.he follows code I tried.
foreach (DataTable dt in dataSet.Tables)
{
foreach (DataColumn dc in dt.Columns)
{
if (dc.DataType == typeof(string))
{
dc.Caption = dc.ColumnName.ToString();
}
}
}
'
However this is not permanent and I don't see results.
Is there a way to make this permanent.
I appreciate any help and thanks in advance.

The Caption property isn't used to set the headers of a DataGridView (for example) when you use it as a DataSource - it probably should have been, but it definitely wasn't!
If you want a "friendly name" for your displayed columns, you need to manually set them on the display control via the "HeaderText" property:
myDataTable = new DataTable();
myDataTable.Columns.Add("C1");
myDataTable.Columns.Add("C2");
myDataTable.Columns[0].Caption = "A new caption";
myDataGridView.Columns.Clear();
myDataGridView.DataSource = myDataTable;
for (int i = 0; i < myDataTable.Columns.Count; i++)
{
myDataGridView.Columns[i].HeaderText = myDataTable.Columns[i].Caption;
}

I have a simple html-document with a button and when someone clicks the button, I would like to execute a C# method. Is this possible? There is no Internet or server involved in this, the html-file and the output (.dll? .exe? something else?) of my C# code will all reside in the same folder on my computer.

Try:
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> Bear in mind that this will do a postback to the Server with all that entails.
To be a bit more sophisticated about it, you would have to use AJAX: AJAX In ASP.NET[^]

But there is no server, just a client.

You can't run C# code on a client - it needs the right .NET framework and that may not be installed.
And besides, if you didn't have a server you would have nothing to load the HTML from in the first place!
I think you need to have a good long think about exactly what you are trying to do, and perhaps research some to find out how these things work. I get the feeling you are just guessing, and that's not a good idea.

You probably need to run your HTML in a web browser control, in a Windows Forms or WPF app, and then hook up to events in the HTML. "Tagging" hidden content with "scripting code" is an added option.

Can a button in html call any function at all? If so, in what programming language? Could I in that case make that programming language call a .dll consisting of my compiled C# code?
|

A button is "dumb"; it doesn't "call anything and everything"; it needs to be "hooked up"; regardless of the platform. You're interfacing with a "document object model". An API.

An HTML button cannot directly call a C# method. The button is in one execution environment and the C# code is in another, even if your HTML and C# code are running client-side.
It sounds like you're trying to use an HTML page as an interface for a desktop app. That's a bad idea.
It can work, but there's a steep price. You'd have to host the ASP.NET runtime in your desktop app. This adds a LOT of overhead and complexity to your app, so it's usually not worth it.
If you're going to go through this pain, it's actually easier to just write up the app as an actual website and host in on the internet.

You are correct that I want a web-browser with an html-file to be the GUI of a (very basic) application that displays text and pictures with basic filter functionality. If I divide it into an html-file and a server written in C#, is it then possible to do both the client-browsing and server-hosting on the same laptop computer, without access to the Internet?
|
|

|

Yes it's possible, though, I wouldn't recommend it.
Google for "C# host ASP.NET in Windows Forms application".

If you consider the Internet to be things outside of your PC then the answer is Yes. However, even if you keep everything on your PC, you will need the PC to host a web server but that can be local to the PC only. So the PC can be stand-alone and not connected to the Internet. This is actually common practice - when you write a web application, you run it on a locally hosted web server and only when all testing has been completed you would publish it to an intranet or extranet web server.

You should read some CodeProject articles starting with Sample HTTP Server Skeleton in C#[^].
EDIT: alternative article: Embedded .NET HTTP Server[^]
I read it again only yesterday; today the link (as many others to CP) seems defective, hope it will get fixed soon.
Using those techniques you can combine any C# functionality you want with an HTTP server of your own, allowing you to get one or more "web pages" from it by using an appropriate URL. Technically speaking your C# code is running on the server, which can reside on the same PC your browser/client is running on.
I've done this a couple of times, it works just fine.
BTW it is advanced stuff and will need some studying...
PS: and then Microsoft is working on its Blazor | Build client web apps with C# | .NET[^] technology where .NET code will actually run inside any browser anywhere, but AFAIK that isn't really available yet.

One of our teachers in C# has asked us why this code is generating error:
class MainClass {
public static void Main (string[] args) {
int a, b;
int soma;
a = 10;
b = 5;
soma = a + b;
Console.WriteLine("Soma ="soma);
}
}
__________
The error it returns is:
main.cs(15,26): error CS1525: Unexpected symbol `soma'
Which means there is something wrong in the "Console.WriteLine" line (line 15 in my code).
Thing is, I can't understand what is missing. Can any seniors point out to me?

You are trying to combine a string with a variable, your console.writeline needs to display a string it cannot work out what Console.WriteLine("Soma ="soma); is. Take a look at the .ToString() method on the variable.

I'm sorry, so my console.writeline should be Console.WriteLine.Tostring("Soma =" soma) ???
Or if not, could you post the correct sequence?
I just realized... all we need is a comma, right? Between the string side and the Variable side.
does
Console.WriteLine("Soma =", soma);
works?

You did not understand what was written, apply the ToString() method to the variable soma. Then you need to concatenate the strings.
