+/**

+ * TCompareValidator class

+ *

+ * TCompareValidator compares the value entered by the user into an input component with the value

+ * entered into another input component or a constant value. To specify the input component to

+ * validate, set the <b>ControlToValidate</b> property to the ID of the input component.

+ *

+ * To compare the associated input component with another input component,

+ * set the <b>ControlToCompare</b> property to the ID of the component to compare with.

+ *

+ * To compare the associated input component with a constant value,

+ * specify the constant value to compare with by setting the <b>ValueToCompare</b> property.

+ *

+ * The <b>ValueType</b> property is used to specify the data type of both comparison values.

+ * Both values are automatically converted to this data type before the comparison operation

+ * is performed. The following value types are supported:

+ * - <b>Integer</b> A 32-bit signed integer data type.

+ * - <b>Double</b> A double-precision floating point number data type.

+ * - <b>Currency</b> A decimal data type that can contain currency symbols.

+ * - <b>Date</b> A date data type. The format follows the GNU date syntax.

+ * - <b>String</b> A string data type.

+ *

+ * Use the <b>Operator</b> property to specify the type of comparison to perform,

+ * such as Equal, NotEqual, GreaterThan, GreaterThanEqual, LessThan, LessThanEqual, DataTypeCheck.

+ * If you set the <b>Operator</b> property to DataTypeCheck, the TCompareValidator component

+ * will ignore the <b>ControlToCompare</b> and <b>ValueToCompare</b> properties and simply

+ * indicates whether the value entered into the input component can be converted to the data type

+ * specified by the <b>ValueType</b> property.
