You can create the custom control as a part of the web application. In this case, you must put the custom control class in the App_Code directory so that it s compiled automatically and made available to all your pages. You can create the custom control in a separate project and compile it into a DLL component. That way, you can keep your control code separate, and you can reuse it in a variety of different web applications. In the following sections, you ll start with the simpler approach (creating the control in the current project) and then graduate to creating a complete, separate, custom control library.

ProgressBar position, will march the bar clear across the screen, as the default maximum value for ProgressBar is 100. You can adjust that maximum via setMax(). For example, you might set the maximum to be the number of database rows you are processing, and update once per row. Note that we then leave onStart(). This is crucial. The onStart() method is invoked on the activity UI thread, so it can update widgets and such. However, that means we need to get out of onStart(), both to let the Handler get its work done and also so Android does not think our activity is stuck. The resulting activity is simply a horizontal progress bar, as shown in Figure 15 1.

Generate Thumbnail Images from PDF Documents - Aspose.PDF for ...
Mar 7, 2019 · This article shows how to generate thumbnail images from PDF documents using first the Acrobat SDK and then Aspose.PDF.

Imagine you want to create a control that looks and acts like a text box but adds some new features that are tailored for working with names (such as Smith, Joe). Thanks to inheritance, this is easier than you d expect. Consider the following example a NameTextBox that adds GetFirstName() and GetLastName() methods. These methods examine the entered text and parse it into a first and last name using one of two recognized formats: space-separated (FirstName LastName) or comma-separated (LastName, FirstName). This way, the user can enter a name in either format, and your code doesn t have to go through the work of parsing the text. Instead, the NameTextBox control handles it automatically.

Public Class NameTextBox Inherits System.Web.UI.WebControls.TextBox Private firstName As String Private lastName As String Public Function GetFirstName() As String UpdateNames() Return firstName End Function Public Function GetLastName() As String UpdateNames() Return lastName End Function Private Sub UpdateNames() Dim commaPos As Integer = Me.Text.IndexOf(",") Dim spacePos As Integer = Me.Text.IndexOf(" ")

As irrational as it sounds, there was a time when visual modeling tools didn t have built-in support for allocation and traceability out of the box (at least not without purchasing six additional software modules at a cost of eleventy-million dollars, and then hiring a team of consultants to manage the interfaces between the tools). These days, however, matters have improved, and we can adopt a much more rational process. For example, Enterprise Architect (EA) provides support for drag-and-drop allocation of requirements and automatic generation of a requirements traceability matrix. We show an example of that later in this chapter.

Dim nameArray() As String If commaPos <> -1 Then nameArray = Me.Text.Split(",") firstName = nameArray(1) lastName = nameArray(0) ElseIf spacePos <> -1 Then nameArray = Me.Text.Split(" ") firstName = nameArray(0) lastName = nameArray(1) Else ' The text has no comma or space. ' It cannot be converted to a name. Throw New InvalidOperationException() End If End Sub End Class

Note Rather than use methods named GetFirstName() and GetLastName(), you could use properties named

Note, though, that while ProgressBar samples like this one show your code arranging to update the progress on the UI thread, for this specific widget, that is not necessary. At least as of Android 1.5, ProgressBar is now UI thread-safe, in that you can update it from any thread, and it will handle the details of performing the actual UI update on the UI thread.

FirstName and LastName. In this example, methods are used because extracting this information involves performing some string parsing, and it could lead to an exception if the information is not in the correct format.
