引 数 説 明


nIndex

Long

取得する情報番号の指定。戻り値は取得した情報。


引 数 に つ い て の 追 加 説 明

次のコードをnIndexに代入することで次の機能を取得することができます。

引数 機能

SM_CLEANBOOT

Windowsのモード。0＝通常、1＝セーフブート、2＝ネットワークを介してのセーフブート

SM_CMOUSEBUTTON

マウスボタンの数

SM_CXCURSOR
SM_CYCURSOR

カーソルの幅と高さ

SM_CXDOUBLECLK SM_CYDOUBLECLK

ダブルクリック領域の幅と高さ。ダブルクリック領域とは、連続する2回のクリックがダブルクリックとみなされる範囲をいう。

SM_CXICON
SM_CYICON

標準アイコンの幅と高さ

SM_CXICONSPACING
SM_CYICONSPACING

デスクトップアイコンの水平方向と垂直方向の間隔

SM_CXMAXIMIZED SM_CYMAXIMIZED

Windows 95の最大化したウィンドウのデフォルトの幅と高さ

SM_CXSMICON
SM_CYSMICON

Windows 95の「小さいアイコン」の幅と高さ

SM_SLOWMACHINE

システムが低速でWindows 95を効率よく利用できない場合はTRUE

まだまだたくさん命令があるのですが、ここでは説明しきれません。詳しくは「Win32 APIプログラマーズリファレンス」(Visual Basicのプロフェッショナルエディション以上やVisual C++などの開発ソフトに含まれています）などを見てください。

サ ン プ ル プ ロ グ ラ ム

Windowsの各種情報を取得するサンプルです。Visual Basicを起動して、新しいプロジェクトを作成し、次のコードを張りつけ実行してください。各種情報を表示して終了します。

動作確認：Visual Basic 5.0(Visual Basic 4.0でも問題なく動作するはずです),Windows98
