Exercise 2: Create Dialog Box

Objectives: Create an “About” Dialog Box to display information of this plug-in. 
This exercise shows the steps to create Dialog Box using Class Attributes.

1. Open the Plug-in project “Tutorial.PRG201” from Exercise 1.

2. Amend the plug-in version to “1.0.2”

3. Right-Click on “Tutorial.PRG201” (Project),

• Select -> Add | Windows Forms…

4. Type the form name as “FormAbout.cs”

5. Edit the Form Text [Properties] Text = "About" 6. Add a Label onto FormAbout at Form Design [Properties] (Name) = lblAbout Text = "Plug-in Tutorial : Getting Started version 1.0.2" 7. Add a button [Properties] (Name) = btnOK Text = &OK

8. Make “About” form appear at the menu.

• Declare the attribute class, using BCE.AutoCount.PlugIn.MenuItem
• Define 1 parameter, and 3 optional parameters
  1. Menu Caption = "About"
  2. BeginNewGroup = true
     (Draw a line one top of this menu)
  3. MenuOrder = 99
     (Set this menu item at bottom)
  4. ShowAsDialog = true
     (Form will not be maximized)

9. Constructor of MenuItem requires one argument

Insert “BCE.Data.DBSetting dbSetting” in the constructor.

[BCE.AutoCount.PlugIn.MenuItem("About", BeginNewGroup = true, MenuOrder = 99, ShowAsDialog = true)]
public partial class FormAbout : Form
{
    public FormAbout(BCE.Data.DBSetting dbSetting)
    {
        InitializeComponent();
    }
}

10. Add below statements into the constructor, which changes FormAbout properties.

11. Add Button [OK] event

• At the “FormAbout” Design, double clicks the button [OK].
• Insert “Close()” in the click event.

public FormAbout(BCE.Data.DBSetting dbSetting)
{
    InitializeComponent();

    StartPosition   = FormStartPosition.CenterScreen;
    FormBorderStyle = FormBorderStyle.FixedDialog;
    MaximizeBox = false;
    MinimizeBox = false;
}

private void btnOK_Click(object sender, EventArgs e)
{
    Close();
}
