Hi,
I am using Reflection to build a GUI based on a class create with XSD, in VB
..NET 2.0. For most elements, I can easily determine the Type and then
provide the user some controls to select what data to use (they are creating
an XML document essentially on the fly). But the choice element has several
possible types and so it creates this itemField as object within the
xs:choice-generated class:
Private itemField As Object
'''<remarks/>
<System.Xml.Ser ialization.XmlE lementAttribute ("DetectionComm and",
GetType(Detecti onCommandType)) , _
System.Xml.Seri alization.XmlEl ementAttribute( "ExtendedComman d",
GetType(Extende dCommandType)), _
System.Xml.Seri alization.XmlEl ementAttribute( "LocationComman d",
GetType(Locatio nCommandType)), _
System.Xml.Seri alization.XmlEl ementAttribute( "SimpleCommand" ,
GetType(SimpleC ommandType)), _
System.Xml.Seri alization.XmlEl ementAttribute( "TimeComman d",
GetType(TimeCom mandType))_
Public Property Item() As Object
Get
Return Me.itemField
End Get
Set(ByVal value As Object)
Me.itemField = Value
End Set
End Property
Is there any way to get the information in the "remarks" section during
runtime, perhaps that auto-generated info is also hiding somewhere else?
Really, I just want be able to determine at runtime what possible Types could
this itemField object take on? I would just throw an enumerated list or some
other hack inside this class, but there are many classes like this and I've
gotten away with a very re-useable solution so far. 1 2938

Hi,
Unless with the explicit declaration of ItemChoiceType enum, I'm not
aware of another way to get it runtime.
You can see detailed sample at: http://msdn.microsoft.com/msdnmag/is...3/06/XMLFiles/

Hi,
I want to consume a Web Service that returns a choice, but my C++ client
always receives the same returned type. On the other hand, when I am using a
Java client, it is working fine (of course, the generated proxy is not the
same).
When I am looking at the C++ generated code, it seems fine, but when I am
executing the code, I always get the first choice type.

<xs:choice maxOccurs=5>
<xs:element name="Foo" type="bar" />
<xs:element name="Foo1" type="bar" />

Is the choice made once and then the choosen element can occur 5 times,
or is the choice made once for each occurance?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
