This code is used to initialize the PDF viewer and the main form.

 

This is what is done here:

 

1) The usual "InitializeComponent()"

2) Call ViewerStart to set the WPViewPDF license key (please modify unless you use the demo)

3) Set the ViewOptions and ViewControls

4) Call command "commands.COMPDF_ACRO_MAKEDRAWOBJ" to make sure loaded PDF files are displayed with editable fields

5) Call command "commands.COMPDF_Ann_SetAnnotSaveMode" to make sure annotations added to a PDF are saved

6) Call the utility function InitMenu with our menu strip and the first and last predefined menu item.

   "doExecuteWPViewAction" will be implemented in next chapter.

 

public Form1()

{

    InitializeComponent();

    // Set some properties

    pdfViewer1.ViewerStart("xxx", "yyy", 0);

 

    pdfViewer1.ViewOptions = eViewOptions.wpExpandAllBookmarks |

    eViewOptions.wpExpandAllBookmarks |

    eViewOptions.wpSelectPage |

    eViewOptions.wpShowPageSelection;

 

    pdfViewer1.ViewControls =

  eViewControls.wpHorzScrollBar |

  eViewControls.wpNavigationPanel |

  eViewControls.wpPropertyPanel |

  eViewControls.wpVertScrollBar |

  eViewControls.wpViewPanel;

 

    pdfViewer1.AllowMovePages = true;

 

 

    // Make sure the annotations work interactively!

    pdfViewer1.Command(commands.COMPDF_ACRO_MAKEDRAWOBJ, "", 8192);  

 

    // enlarge the zoom buttons

     pdfViewer1.Command(commands.COMPDF_SETBUTTONHEIGHT, 32 );

 

    // Standard Action Mode 'Click + Pan'

     pdfViewer1.Command(commands.COMPDF_SetActionMode,"",1);

 

    // ENABLE saving of annotations

     pdfViewer1.Command(commands.COMPDF_Ann_SetAnnotSaveMode, 1);

 

    // Load the menu from the embedded actions

     pdfViewer1.InitMainMenu(menuStrip1,

          doExecuteWPViewAction,

          fileToolStripMenuItem,

          infoToolStripMenuItem);

 

     // Initialize the toolbar

     InitToolbar(toolStrip1, _ActionButtons );
