This topic shows how to convert the bytes from a byte array into a string.
Powershell Create Array From String
Easy - Read a file into a array. Ask Question 0. Reasonable answer apart from the method used to read a text file into a string. It has some problems - why not use the 3-line technique from the VB6 manual instead? Browse other questions tagged arrays file vb6 or ask your own question. 8 years, 10 months ago. Dec 01, 2012 Without adding a reference to a PDF reader of some sort then you are pretty much stuck with writing it to a file and then calling whatever PDF reader is installed on the machine. The following code will write your byte array to a pdf document, then load it in the currently installed pdf. Oct 15, 2012 More easy way is to use generic List. List Files = Directory.GetFiles(strFullpath, '*pdf').Select(path => Path.GetFileName(path)).ToList(); Then you can add more strings as, Files.Add ('New1 Record 1'); Files.Add ('New1 Record 2'); I hope this helps. Please mark this post as answer if it solved your problem.
Example
Download apriori algorithm source code in c. This example uses the GetString method of the Encoding.Unicode encoding class to convert all the bytes from a byte array into a string.
Gaem java layar ful kerajan. You can choose from several encoding options to convert a byte array into a string:
- Encoding.ASCII: Gets an encoding for the ASCII (7-bit) character set.
- Encoding.BigEndianUnicode: Gets an encoding for the UTF-16 format using the big-endian byte order.
- Encoding.Default: Gets an encoding for the system's current ANSI code page.
- Encoding.Unicode: Gets an encoding for the UTF-16 format using the little-endian byte order.
- Encoding.UTF32: Gets an encoding for the UTF-32 format using the little-endian byte order.
- Encoding.UTF7: Gets an encoding for the UTF-7 format.
- Encoding.UTF8: Gets an encoding for the UTF-8 format.

Introduction
Recently, I had to make a VB.NET program that reads PDF file contents and replace it with customized text. VB.NET unfortunately doesn't have a built in PDF file reader object, so I had to make use of a third party's product called iTextSharp. From the moment I started using it, I fell in love with it. With this article I will demonstrate how to use iTextSharp with VB.NET to manipulate PDF files.
PDF files
A detailed explanation of PDF files can be found here.

iTextSharp
Php Create Array From String
A detailed explanation, and download of iTextSharp can be found here. As you can see, iTextSharp is mostly for C# and Java; hence this Visual Basic.NET article.I would suggest that you go through the documentation properly before proceeding with our project. I cannot do everything for you, you need to have some input as well.
Our Project
Purpose
Our project's aim is to read from a PDF file, change some of the contents and then add a watermark to the PDF document's pages. Sound easy enough, yes, with the help of the iTextSharp library you will see how simple it is.
Design
Our project doesn't have much of a design. All we need is a progress bar and a button. Mine looks like Figure 1 :

Code
Before we can jump in and code, you need to make sure that you have downloaded the iTextSharp libraries. How to download netflix to watch on mac. Once that is done, we need to add a reference to it by clicking Project->Add Reference->iTextSharp.dll. Once we have the project reference set up, we need to reference the iTextSharp libraries in our code. Add the following Imports statements:
This imports all the needed capabilities for our little program. Now the fun starts! Add the following Sub Procedure:
Oye! What a mouthful!
Before you freak out; this code is actually not so bad. Let's have a look at it step by step:
- We create a Stamper object and a Content object. The Stamper object is to enable us to write our content onto the PDF file. The content object helps us to identify the appropriate content on the file that we need to replace.
- We determine if the PDF file exists, and read its underlying content. We also set up our ProgressBar to compensate for the amount of pages in the PDF document.
- We commence our For Loop (to loop through each page) and create a LocationTextExtractionStrategy object. This object enables us to extract our desired text. This class also forms part of the iTextSharp download. We need to add this file to our project - but we'll do that a bit later.
- Once we know what text we need, and what diameters the text use, we could continue to loop through all the pages until a match is found. We store each match and create a new layer for each match to be replaced.
- We then replace the found text with our new layer that is filled in order to highlight our change. The trick here is to replace the layer's exact dimensions. A PDF file does not work similar to a Word document where we could just find and replace text. Why? Because each little word or phrase is actually a block, or a layer; so, to replace that particular block, we need the exact dimensions. If we do not have the exact dimensions, the layered text will not appear at the exact same place.
- Lastly, we include a call to the AddPDFWatermark sub (which we will create now) to add a watermark on each page. The file that is written will be stored onto the C:.
Make sense now?
Add the next Sub procedure:

You will notice that here, we almost do the same as we did in the previous sub. The only difference here is that we added an image to the undercontent of each page, instead of replacing textlayers.
The last piece of code we need to add for this form is the call to the ReplacePDFText sub from our start button:
This calls the sub to replace PDF content, and writes the new PDF file to a location on C:. Now, we will have two files. La lumina lunii serial online. Obviously, this is just and example and it would be easy to combine all of the changes into one file.

This file forms part of the iTextSharp download I mentioned earlier. We need to add this file as is, to our project. Remember, we didn't create this file or logic, neither have I. But without this file we will not be able to identify the content strings we are looking for. This demonstrates the real power of iTextSharp, and this is why iTextSharp is my preferred choice when it comes to doing any PDF manipulation.
Add a new class and add the following to it (in case you didn't download the iTextSharp files at the location I've mentioned):
All we need to do now is to import this namespace into our form. Add the following Imports statement to your form's code:

If we run our project now, it will work as intended.
I am including my project below for you to download. Sadly, the iTextSharp.dll is quite big, and unfortunately too big to include here; so you need to download it through the steps I have outlined for you.

Conclusion
Thank you for reading my article. Obviously, I am only human (don't be so surprised!), and I can only do so much; but I couldn't have written this article if it wasn't for some help I received from a gentleman called jcis. Thank you - sometimes I bite off more than I can chew.
I hope you have enjoyed this article, and actually learned a thing or two from it. Now I'm off to see what new projects I can do and why VB.NET always seem to be second choice and C# first choice for real hardcore complicated projects.
