Windows NT と Windows 95 以降のアーキテクチャは、32 ビットであるためには、16 ビット API の Windows 3.x からいくつかの違い、アプリケーション プログラミング インターフェイス (API) があります。 ここでは 32 ビット オペレーティング環境では、コードが正常に実行されるよう 32 ビット API 呼び出しを 16 ビット API 呼び出しを含むコードを変換する方法。 この記事では次の項目を取り扱います：
API を持つプロシージャを宣言するときに、プロシージャ名に別名を使用します。 エイリアスを関数名から一意になければなりません。 、ない場合、別名が自動的に削除されます。
関数によって返されるデータ型または関数に渡されたパラメーターのデータ型を宣言する場合は、型宣言文字 (%、$ という) ではなく As 句を使用します。
Microsoft Access 開発者用ツールキットの Windows 95、Microsoft Office 97 開発 Edition、および Visual Basic 4. 0 API の使用が簡単が含まれている便利なユーティリティもあります。 API ビューアーと呼ばれます。 宣言、定数、および任意のテキスト ファイルまたは API の情報が含まれている Microsoft Jet データベースに含まれている型を参照できます。 これらの項目をクリップボードにコピーでき、コードに貼り付けます。
