+/**
+ * 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.
