Syntax
'Declaration
 
Public Property AttributeValues As AEAttributeValueDictionary
'Usage
 
Dim instance As AEEventData
Dim value As AEAttributeValueDictionary
 
instance.AttributeValues = value
 
value = instance.AttributeValues
public AEAttributeValueDictionary AttributeValues {get; set;}
public:
property AEAttributeValueDictionary^ AttributeValues {
   AEAttributeValueDictionary^ get();
   void set (    AEAttributeValueDictionary^ value);
}

Property Value

The value of this property cannot be null (Nothing in Visual Basic).

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

Attributes are vendor-specific.

If a server cannot provide reasonable data for an attribute, the returned VARIANT should be set to VT_EMPTY.

This is a dictionary where the key is attribute ID, and the value is the actual value of that event attribute.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
