Generating PDFs in Java using iText. Support for Free flowing text -

-

We have the following nature's PDF templates that need to be generated by web applications:

Sample Paragraph:

Dear {customer.name},

Your attorney, {customer.lawyer.name}, has contacted us about your account, {customer.account.number } Requesting an immediate closure of the account.

...

The {...} fields given above are for adjusting the various Actor areas which will be placed as placeholders, so that they are populated with data .

But the problem is that the field {customer.lawyer.name} can be of different lengths, ranging from 10 to 50 characters,

using iText, how can we Are you generating a PDF for the above mentioned template so that the different lengths of the variable can be adjusted? Maybe wrap the text appropriately anywhere?

I used iText columns for layout letters. Here's an example from my work, note that I just typed it in the stack overflow, I have not compiled or tested it.

Imagine a file where two new lines in the row point to the paragraph, the text is wrapped by the editor. The following classes come up with a method that reads the file and a U.S. Letter size pdf emits up and down and 1 1/2 inch margins on each side with 1 inch margin. 

  ** generates a letter * / public class letter generator {/ ** one inch is 72 digits * / personal last fixed int INCH = 72; / ** Generate a letter * / Public Zero generated () throws document Exception, IOException {BufferedReader = New BufferedReader (New FileReader ("letter.txt")); Document document = new document (pages aliiter); PdfWriter.getInstance (document, new FileOutputStream ("letter.pdf")); PdfContentByte CB = Writer. Gate Direct Content (); Column reader CT = new column text (CB); String paragraph; Int spacingBefore = 0; While ((para = in. Readline ()) = null {line = line.trim (); If (line.length ()! = 0) {// Shekhar, transfer your place holder to here. Paragraph p = new paragraph (line); P.setSpacingBefore (spacingBefore); Ct.addElement (P); Interval = 8; }} Ct.setSimpleColumn (INCH, INCH * 1.5f, 7.5f * INCH, 9.5f * INCH); Int Status = Column Text. START_COLUMN; While ((Status and column text .NO_MORE_TEXT) == 0) {status = ct.go (); Ct.setYLine (PageSize.LETTER.getHeight () - INCH); Ct.setSimpleColumn (INCH, INCH * 1.5f, 7.5f * INCH, 9.5f * INCH); Document.newPage (); } Document.close (); }}

For my life, I do not remember why I reset the Y-line.

iText is a great library, I have learned the most about it, which I know about it in the tutorials through the eText in the Action Book.

Unfortunately, I have never bought a book.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
