Q&A

  1. I want to be able to use control arrays to handle multiple events. Where did that functionality go?

  2. Control arrays do not exist in Visual Basic .NET. Each control you add has its own event that you can write code for. You can, however, handle multiple events with a single method. You did this earlier with the genericClick event in the forms exercises. You can also use the Handles keyword to indicate what events a method should consume, as the following code demonstrates:

    Private Sub Button5_Click(ByVal sender As System.Object, _
     ByVal e As System.EventArgs) _
     Handles Button5.Click, Button3.Click, Button4.Click, Button2.Click
    
    End Sub
  3. Can I use ActiveX controls from Visual Basic 6 in my .NET Windows Forms applications?

  4. Yes, you can. Although the interop between COM and .NET has some overhead, the functionality is built in. To add an ActiveX control to the Toolbox, you can right-click on the Toolbox and select Customize. From this dialog, you can select the ActiveX controls to add to your application. Most third-party vendors have .NET certified controls. For some of the more popular controls, visit http://www.infragistics.com and http://www.componentone.com.

  5. Windows Forms are awesome. Where can I get more details? The QuickStart tutorials only take me so far.

  6. Microsoft has a Web site specifically for Windows Forms. Check out http://www.windowsforms.net to get tons of great information about developing forms applications.
