Enum problem

[MSNEWS]

HI

Public Enum WindowStyles As UInteger
WS_OVERLAPPED = 0x00000000
WS_POPUP = 0x80000000
WS_CHILD = 0x40000000
end enum
In the above i get an error at
0x00000000 , 0x80000000 , 0x40000000
message "End of statement expected"

how do i correct them

TIA
Barry

In VB.NET you don't use the C++ way of specifying hex. Use this instead:

Public Enum WindowStyles As UInteger
WS_OVERLAPPED = &H00000000
WS_POPUP = &H80000000
WS_CHILD = &H40000000
end enum

Thank you guys for your quick response.

I am basically trying to convert a C# app to VB.NET

I am stiil getting a error at &0x00000 (near &) in VS 2005

message is "Expression expected"

ok... you''ve peeked my interest now :)

This should be pretty simple, but I haven't dealt with hex numbers in a while
so I there could definitley be mistakes in here somewhere :).

I converted the code myself in my copy of VS2005

-------------------------------------------------------------
Public Enum WindowStyles As UInteger
WS_OVERLAPPED = &H0
WS_POPUP = &H80000000
WS_CHILD = &H40000000
End Enum
-------------------------------------------------------------

After this convertion I found myself with an error, no where you suggested,
but instead under the value '&h80000000'.
It seems that this number falls outside of the allowed range of a UInteger.

Closer evaluation leads me to believe that this is in fact a negative number
(-2147483648) this will clearly not fit inside an unsigned integer (UInteger
) as this only allows positive numbers.

Either your values are wrong or alternatively this enum should be based on
an Integer rather than a UInteger.

I have looked up the value of WS_popup and it seems to be correct.

Therefore, as far as I can tell, your code should read...
-------------------------------------------------------------
Public Enum WindowStyles As Integer
WS_OVERLAPPED = &H0
WS_POPUP = &H80000000
WS_CHILD = &H40000000
End Enum
-------------------------------------------------------------
... which yields no errors on my system
I hope this helps

Hi Rory

Does this mean i will have to convert all values to Hex (&H0 etc) ??

I find that the following value do not give any error

WM_SYSCOLORCHAN GE = 0x0015

WM_ENDSESSION = 0x0016

WM_SHOWWINDOW = 0x0018

WM_WININICHANGE = 0x001A

WM_SETTINGCHANG E = 0x001A

WM_DEVMODECHANG E = 0x001B

WM_ACTIVATEAPP = 0x001C

WM_FONTCHANGE = 0x001D

WM_TIMECHANGE = 0x001E

WM_CANCELMODE = 0x001F

WM_SETCURSOR = 0x0020

WM_MOUSEACTIVAT E = 0x0021

whereas these give an error

WM_NULL = 0x0000

WM_CREATE = 0x0001

WM_DESTROY = 0x0002

WM_MOVE = 0x0003

WM_SIZE = 0x0005

WM_ACTIVATE = 0x0006

WM_SETFOCUS = 0x0007

WM_KILLFOCUS = 0x0008

WM_ENABLE = 0x000A

WM_SETREDRAW = 0x000B

WM_SETTEXT = 0x000C

WM_GETTEXT = 0x000D

WM_GETTEXTLENGT H = 0x000E

WM_PAINT = 0x000F

WM_CLOSE = 0x0010

WM_QUERYENDSESS ION = 0x0011

WM_QUIT = 0x0012

WM_QUERYOPEN = 0x0013

WM_ERASEBKGND = 0x0014

To me this looks like a bug, walks like a bug and quacks like bug. I
may be wrong, though. Anyway, add a "&" to the end of the value and
everything will seem to fit ("&" is the "type-character" used to
designate Integers). Did I say how much this resembles a bug, to me?

Public Enum WindowStyles As UInteger

WS_OVERLAPPED
WS_POPUP = &H80000000&

WS_CHILD = &H40000000
End Enum

HTH.

I'm not sure I understand

A number expressed 0x0010 is already in hex. It translates to 16 in decimal

by exchanging the '0x' for '&h' you are simply switching from a c-style syntax
to vb-style syntax

There is no changing into hex occuring here

I get no errors with any of the values you have given when I do this.

What errors are you getting now. Are they Runtime or design time?

I'm concerned that you may be puting '&h' or '0x' on the front of just any
number. If these symbols were not on the front of a number, then introducing
them will alter their value.

Hex is just a way of qualifying some digits

You could write
-------------------------------------------------------------
Enum SomeEnum as Integer
Value1 = &h0010
Value2 = &h0011
End Enum
-------------------------------------------------------------
or
-------------------------------------------------------------
Enum SomeEnum as Integer
Value1 = 16
Value2 = 17
End Enum
-------------------------------------------------------------
either means the same thing.

Can you explain what you are trying to do?
Perhaps a complete code sample.
Try for the smallest code sample that acurately portrays the problem you
are seeing.

<snip>

What do you mean 'don't give any error'? The notation you're using
comes straight from C/C++. In VB, if you want to represent a value in
hexadecimal you must prepend "&H" in front of the value (i.e., replace
every "0x" by "&H" in the values above). Also note that leading zeroes
in hex numbers can be ommited (this is also true in C/C++). Therefore
both &h1A and &h001A represent the same value. Finally, remember that
the hexadecimal representation is just that, a representation. The
underlying value is still an Integer (or UInteger, or Byte, etc,
depending on how you declared the variable or enum to which the value
is being assigned). In other words, there's no difference to the
compiler if you say

WM_SETCURSOR = &H20

or

WM_SETCURSOR = 32 'the corresponding decimal value

Using the values in hexadecimal has only meaning to you, the
programmer, who can be more comfortable with seeing Windows messages
IDs represented as hexadecimal. Another programmer could prefer
something like this, instead (not that I know any programmer that
would):

<aircode>
Enum WindowsMessages
WM_NULL 'the first enum is 0 by default
WM_CREATE
WM_DESTROY
WM_MOVE
WM_SIZE = WM_MOVE +2
WM_ACTIVATE
WM_SETFOCUS
WM_KILLFOCUS
WM_ENABLE = WM_KILLFOCUS + 2
WM_SETREDRAW
WM_SETTEXT
WM_GETTEXT
WM_GETTEXTLENGT H
WM_PAINT
WM_CLOSE
WM_QUERYENDSESS ION
WM_QUIT
WM_QUERYOPEN
WM_ERASEBKGND
WM_SYSCOLORCHAN GE
WM_ENDSESSION
WM_SHOWWINDOW = WM_ENDSESSION + 2
WM_WININICHANGE = WM_SHOWWINDOW + 2
WM_SETTINGCHANG E = WM_WININICHANGE
WM_DEVMODECHANG E
WM_ACTIVATEAPP
WM_FONTCHANGE
WM_TIMECHANGE
WM_CANCELMODE
WM_SETCURSOR
WM_MOUSEACTIVAT E
'...
End Enum
</aircode>

whereas these give an error

WM_NULL = 0x0000
WM_CREATE = 0x0001
WM_DESTROY = 0x0002
WM_MOVE = 0x0003
WM_SIZE = 0x0005
WM_ACTIVATE = 0x0006
WM_SETFOCUS = 0x0007
WM_KILLFOCUS = 0x0008
WM_ENABLE = 0x000A
WM_SETREDRAW = 0x000B
WM_SETTEXT = 0x000C
WM_GETTEXT = 0x000D
WM_GETTEXTLENGT H = 0x000E
WM_PAINT = 0x000F
WM_CLOSE = 0x0010
WM_QUERYENDSESS ION = 0x0011
WM_QUIT = 0x0012
WM_QUERYOPEN = 0x0013
WM_ERASEBKGND = 0x0014

There shouldn't be any errors in these values (after you replace "0x"
by "&H", I mean). What kind of problem are you having?

Branco.
