C# – How to include help ‘?’ in title bar of winform

cwinforms

I am trying to add a help '?' button to the title bar (along with minimize, maximize, and close buttons) of my winforms application (C#.NET 2.0). I have tried using the Help Button property of Form, but it does not work. Any suggestions?

The Help icon is only there when HelpButton = True and MaximizeBox and MimizeBox are both set to False. This is the windows standard. If you really want to go beyond and add a button anyway, you'll have to customize the titlebar.

This is not an easy task, it either involves many hooks, or a complete redesign of the title bar.

Are you sure you want to depart from the Windows standard? Wouldn't it be better to have Help available in the menu or on a toolbar somewhere?

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
}

Note: The cast to (Suit[]) is not strictly necessary, but it does make the code 0.5 ns faster.
