注釈

このプロパティを使用して、郵便番号や電話番号などの値をコントロールに入力したテキストの長さを制限することができます。You can use this property to restrict the length of text entered in the control for values such as postal codes and telephone numbers. データがコントロールに入力したテキストが、データベース内の対応するフィールドの最大長を超えないように、データベースに格納されるときに入力したテキストの長さを制限するのに、このプロパティを使用することもできます。You can also use this property to restrict the length of text entered when the data is to be stored in a database so that the text entered into the control does not exceed the maximum length of the corresponding field in the database.

このプロパティは、プログラムによって追加された文字には影響しません。This property does not affect characters that are added programmatically.

このプロパティが 0 に設定されている場合は、コントロールに入力できるテキストの最大の長さが使用可能なメモリによってのみ制限されます。When this property is set to 0, the maximum length of the text that can be entered in the control is limited only by available memory.
