How to read a file from any kind of documents and display its contents?

[CoderForEver]

Hi my friends ........ I want to do term weighting by an approach called Composite measure(Tf*idf) ... it has its own formula .... But what I want to do is to read files like(Word 2003,2007 pdf files etc.... ) then to take each word as an array .... I can read all files line by line by the following code try { // Create an instance of StreamReader to read from a file. // The using statement also closes the StreamReader. using (StreamReader sr = new StreamReader(textBox1.Text,Encoding.ASCII,true))// Where textbox1.text is a path { String line; // Read and display lines from the file until the end of // the file is reached. while ((line = sr.ReadLine()) != null) { richTextBox1.Text =richTextBox1.Text +Environment.NewLine+ line; //MessageBox.Show(line); } } } and to check the content of the file i tried to display it on a Richtextbox1 .... but it displays encrypted file ..... What I want to know is 1. How can I put each words(separated by Space and newline) in to array ... just to know each word (here displaying the content is not necessary) 2. How can I display the content of each file on Richtextbox1 ... but not in an encrypted form .... Thanks for your help

The first thing you need to know is: Word and PDF files (as well as many others) are not necesarily line based text documents. Instead they are frequently binary files - which explains why they look encrypted. The second thing you need to know is: Word and PDF files can be encrypted. So that may be why they lookm encrypted. Google for "Word File Format" and "PDF File Format" - this will provide a starting point for you to gather the information you are going to need.

So how can i decrypt them? .... or can you tell me how to work on them please? Just u can see my first question. Thank you

Or forget about the Pdf and Word ... but how do i gather the words in an array ... in just a text document ... Thank you

I couldn't open them either, using Chrome. It works in FF though :)

Each document has a specific structure. Word-documents and PDF files can't be "read", because the computer doesn't know how to read them. Those documents contain extra information like "this part text in bold formatting", and "this in red". All that information is stored in between the words that you see when you open the thing in Word.

You can't until you have something to decode the file. You can save Word-files as RTF. Take a look at the result with a text-editor, and you'll see where the extra codes are located. You can also save the file as HTML. Again, a coded form, just like the binary representation.

Use string.split with a blank space as your separator to populate an array of just each individual word. check out the documentation[^] for more basic string manipulation.

Check out the CodeProject forum Guidelines[^] The original soapbox 1.0 is back![^]

One way to do this would be to use the Index Server IFilter approach and read the words this way, outlined here[^].

So can I read this RTF file .... then display it on Richtext box ? ... or what is left? Thnk you for your help

Decrypt: First, find out the password... Because they aren't stored as straight text, you can't just read them and identify the words. The files contain heaps of other stuff: font, size, colour, location, lines, boxes, italics, bold, pictures, spreadsheets, etc. etc. etc. If all you are interested in is the text of the document and doing some textual analysis, then the best thing you can do is to throw away as much of the formatting as possible, and save the file as a straight .TXT file from Word and/or PDF. You can then read the whole thing in, and use string.Split (with space and reasonable puncuation) to break it into words.

It's a picture and a caption - nothing special, and certainly nothing exotic. If Chrome can't open something that simple, I'd certainly entertain the idea of using one of the alternative browsers for my regular web-browsing pleasures...

if you use a CRichEditCtrl, you can directly load RTF files. Sorry 'bout that.... Well, we're in the C# forum, so use the equivalent C# control, I'm certain you can so the same thing. see http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.loadfile.aspx[^] (is that correct, I'm no C# expert) Max.

Yup. The same method can be used to read plain text files. If you want to read another format, then you'll have to provide methods to read those formats. Reading Word-files directly is a fair bit more complex.

You could also entertain the idea of installing multiple browsers. It's not a marriage, and I'm not going to commit to a single system :)

Well, IE 6 and 8 show it just fine without any special compatibility tags.
