Hello. In project Visual Studio 2008, Visual C#, Windows Forms Application,
I have written down such code on C# without errors:

        [Flags]

        public enum WindowStyles : uint

        {

            Overlapped = 0x00000000,

            Popup = 0x80000000,

            Child = 0x40000000,

            Minimize = 0x20000000,

            Visible = 0x10000000,

            Disabled = 0x08000000,

            ClipSiblings = 0x04000000,

            ClipChildren = 0x02000000,

            Maximize = 0x01000000,

            Caption = 0x00C00000,

            Border = 0x00800000,

            DialogFrame = 0x00400000,

            VerticalScroll = 0x00200000,

            HorizontalScroll = 0x00100000,

            SystemMenu = 0x00080000,

            ThickFrame = 0x00040000,

            Group = 0x00020000,

            TabStop = 0x00010000,

            MinimizeBox = 0x00020000,

            MaximizeBox = 0x00010000,

        }

x = unchecked((int)0x80000000);

y = 0xffff;

z = 0x0040;

The same code, I have copied in the project Visual Studio 2008, Visual
Basic, Windows Forms Application  in such kind on Visual Basic:

        <Flags()> _

        Public Enum WindowStyles As UInteger

            Overlapped

            Popup

            Child

            Minimize

            Visible

            Disabled

            ClipSiblings

            ClipChildren

            Maximize

            Caption

            Border

            DialogFrame

            VerticalScroll

            HorizontalScroll

            SystemMenu

            ThickFrame

            Group

            TabStop

            MinimizeBox

            MaximizeBox

        End Enum

x = 0

y = 0

z = 0

Building the program occurs without errors, however the result of
performance of the program turns out erroneous.

Inform, please, how correctly to write down this code on Visual Basic?

Many thanks, Zharkov, Moskva, Rossiya.

That's because you still have to give values to each constant inside
the enumerator: example:
Code: 
<Flags()> Enum MyFlags
None = 0
First = &H1
Second = &H2
Third = &H4
Fourth = Third << 1 'also a possible way of defining a constant in
terms of the other one, Forth is equal to &H8 right now.
End Enum

Many thanks for the answer.

Following your code, I have correctly written down last three lines
of a code?

x = unchecked((int)0x80000000); --> Dim x As Integer = &H80000000

z = 0x0040; --> z = &H40



And how to write on Visual Basic last line?

y = 0xffff; --> ?

Many thanks, Zharkov.

Replace 0x with &H.

The translation depends on the data type of the variables 'x', 'y', and 'z'
respectively. '0x0040' translates to '&H40' and '0xffff' translates to
'&HFFFF', however, you may have to append the proper type suffices in order
to get it work.

Most posts get adjusted to the local time zone of the person viewing them. Your
posts do not. It is not a big problem, it just means that somewhere between here
and there the time zone information is getting lost.

Since you wrote your post at about 6 am Tuesday morning, Moscow time, it looks
odd to see it listed that way on the west coast of the USA, where it is only
8:30 pm Monday.

Mr. Steve Gerrard.

Thanks for an explanation. Look, please, the program in my last post from 2
March. You see in the program of errors?

Thanks, Zharkov.
