27.9   Dos Class

We will briefly review the Dos70 library introduced in the last chapter. We will use the �Attrasoft.Transapplet70.Dos70� library; please read the last chapter to become familiar with this library.

The main class in this library will be:

    Attrasoft.TransApplet70.Dos70.Dos70.

The interface, which is implemented by Dos70, is:

    public interface I_Dos70

    {

    //Parameters

 string getFilePath ();

      void setFilePath (string s);

    

    // Command

      bool save (int i);

      bool open (int i );

      bool load ();

      bool run();

      bool ImageFinderForDos (int i);

    }

To set the batch file, use:

 string getFilePath ();

     void setFilePath (string s).

There is only one command:

    bool ImageFinderForDos (int x).

which is the same as:

bool open (int i );

    bool run();

The parameter, x, can have the following values: 1, 2, 3, 4, 5.

•    Value 1 corresponds to the ImageFinder command: �Batch/Open� + �Batch/Run�;
•    Value 2 corresponds to the ImageFinder command: �Batch/Open 2� + �Batch/Run�; � 

To include the class library in the project,

•    In the Solution Explorer, right click References and select Add Reference;
•    Browse to find �Dos70.dll� in �c:\transapplet70\�;
•    Highlight it and click the �OK� button.

To declare an object, add:

Attrasoft.TransApplet70.Dos70.Dos70 d70

= new Attrasoft.TransApplet70.Dos70.Dos70 ();
