定数

注釈

これらのグローバル カウンターは、Windows コンポーネントの状態が時間の経過と同時に変化したかどうかを識別するのに役立つ共有変数です。 これらは、 SHGlobalCounterDecrement、 SHGlobalCounterIncrement、 SHGlobalCounterGetValue の各関数で使用できます。

例

void ValidateSomeSettings()
    {
        // Get the current GLOBALCOUNTER_SHELLSETTINGSCHANGED value.
        long lGlobalSettingsCounter = SHGlobalCounterGetValue(GLOBALCOUNTER_SHELLSETTINGSCHANGED);
            
        // Do some other work
        ...
    
        // Verify whether the Shell settings have changed since entering this method.
        if (lGlobalSettingsCounter == SHGlobalCounterGetValue(GLOBALCOUNTER_SHELLSETTINGSCHANGED))
        {
            // Commit the work that was done earlier 
            ...
        }
    
        else
        {
            // Shell settings have changed. Rollback and redo.
            ...
        }
    }
