Java IText: Modifying Existing PDF Documents - Jenkov Tutorials
May 24, 2014 · If you already have a finished PDF, and just want to add a header, footer or watermark to it, IText provides the com.itextpdf.pdf.PdfStamper class. First you read the existing document using a PdfReader , then modify it using the PdfStamper .

In our example, we defined two keys: host and email The former key stores the value of the SMTP host, and the latter stores your email address Now open the code-behind web form and modify the Click event handler of the Submit button as shown in Listing 11-21 Listing 11-21 Retrieving Values from the <appSettings> Section protected void Button1_Click(object sender, EventArgs e) { string host = ConfigurationManagerAppSettings["host"]; string email = ConfigurationManagerAppSettings["email"]; SmtpClient client = new SmtpClient(host); clientCredentials = CredentialCacheDefaultNetworkCredentials; MailMessage msg = new MailMessage(); msgFrom = new MailAddress(TextBox2Text); msgToAdd(email); msgSubject = TextBox3Text; msgBody = "[" + DropDownList1SelectedItemText + "]" + TextBox4Text + "\r\n" + TextBox1Text + "\r\n" + TextBox5Text; clientSend(msg); Label9Text = "Your message has been sent Thank you!"; } Observe the code marked in bold.

BehaviorEditorPart To support editing the behavior of a WebPart or GenericWebPart, ASP .NET provides the BehaviorEditorPart. LayoutEditorPart The LayoutEditorPart is for editing the layout properties and associated WebPart (or GenericWebPart control) .

The code uses a class called ConfigurationManager, which resides in the SystemConfiguration namespace By default SystemConfiguration is imported in the code-behind The AppSettings property of the ConfigurationManager class exposes the entire <appSettings> section as a NameValueCollection You can access individual values by using an index or a key name, though it is more common to access them by using key names..

let sumIfBothSmall (inp1,inp2) = attempt { let! n1 = failIfBig inp1 let! n2 = failIfBig inp2 let sum = n1 + n2 return sum } In this case, the let binding executes exactly as you would expect; it takes the expression n1+n2 and binds its result to the value sum. To summarize, you ve seen that computation expressions let you do the following: Use an expression-like syntax to build Attempt computations Sequence these computations together using the let! construct Return results from these computations using return and return! Compute intermediate results using let

When is this useful Quite frequently. In fact, whenever a parent-child relationship exists between tables, despite the fact that referential integrity is maintained, some parent rows may not have related rows in the child table, since child rows may be allowed to have null foreign key values and therefore not match any row in the parent table. This situation doesn t exist in the original Orders and Employees data, so you ll have to add some data before you can see the effect of outer joins. You need to add an employee so you have a row in the Employees table that doesn t have related rows in Orders. To keep things simple, you ll provide data only for the columns that aren t nullable.
