This enumeration contains values that you can use to describe the type code for a value in XAML for Windows Embedded.

Syntax

enum VALUE_TYPE
    {
                VTYPE_NONE = 0,
                VTYPE_FLOAT = 1,
                VTYPE_INT = 2,
                VTYPE_BOOL = 3,
                VTYPE_UINT = 4,
                VTYPE_COLOR = 5,
                VTYPE_READONLY_STRING = 6,
                VTYPE_BSTR = 7,
                VTYPE_POINT = 8,
                VTYPE_RECT = 9,
                VTYPE_THICKNESS = 10,
                VTYPE_SIZE = 11,
                VTYPE_GRIDLENGTH = 12,
                VTYPE_CORNER_RADIUS = 13,
                VTYPE_OBJECT = 14,
                VTYPE_PROPERTYBAG = 15,
                VTYPE_ENUMERABLE = 16,
    };

Members

    Indicates an unassigned type.
  • VTYPE_FLOAT
    Indicates a float value type.
  • VTYPE_INT
    Indicates a 32-bit signed integer value type.
  • VTYPE_BOOL
    Indicates a Boolean value type.
  • VTYPE_UINT
    Indicates a 32-bit integer enumeration type.
  • VTYPE_COLOR
    Indicates an RGB COLORREF value type.
  • VTYPE_READONLY_STRING
    Indicates a length-specified read-only Unicode string type.
  • VTYPE_BSTR
    Indicates a BSTR string type.
  • VTYPE_POINT

  • VTYPE_RECT
    Indicates an XRRect structure type that contains left, top, right, and bottom values.
  • VTYPE_THICKNESS
    Indicates an XRThickness structure type that contains left, top, right, and bottom values.
  • VTYPE_SIZE
    Indicates an XRSize structure type that contains a pair of float values.
  • VTYPE_GRIDLENGTH
    Indicates an XRGridLength structure type that specifies row and column dimensions.

Remarks

The enumerated types in VALUE_TYPE provide different value types for a dependency property or attached property.

For implementing a custom method, use VTYPE_READONLY_STRING for all read-only [in] parameters and use VTYPE_BSTR for [out] or [in, out] parameters where transfer of ownership occurs.

.NET Framework Equivalent

None.
