ComAliasNameAttribute ComAliasNameAttribute ComAliasNameAttribute ComAliasNameAttribute Class

Definition

Indicates the COM alias for a parameter or field type.

Examples

In the following type library, OLE_COLOR is an alias for int. During import, the arguments of the Color accessor are marked with the ComAliasNameAttribute to indicate that type library refers to them as OLE_COLOR.


typedef int OLE_COLOR;    

interface Baz {  
 HRESULT SetColor([in] OLE_COLOR cl);  
 HRESULT GetColor([out, retval] OLE_COLOR *cl);  
}  

is imported as:

interface class Baz
{
   void SetColor( [ComAliasName("stdole.OLE_COLOR")]int cl );

   [returnvalue:ComAliasName("stdole.OLE_COLOR")]
   int GetColor();
};

interface Baz {
 void SetColor([ComAliasName("stdole.OLE_COLOR")] int cl);
 [return: ComAliasName("stdole.OLE_COLOR")] int GetColor();
}
Interface Baz
    Sub SetColor( <ComAliasName("stdole.OLE_COLOR")> cl As Integer)
    Function GetColor() As <ComAliasName("stdole.OLE_COLOR")> Integer
End Interface

Remarks

You can apply this attribute to parameters, fields, properties, or return values.
