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...

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 Smile | :)

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.

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

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.

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.

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)

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.

~~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.

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.

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

How to check if particular class is user defined?

Hi All,

I am writing an application in which I need to put check if a class is user defined or built in (C# or .Net).

Can someone help me with this?

Thanks,

This might not be the ideal solution, but you can get the namespace of a type. You could check whether the class part of the "System" or "Microsoft" namespaces Smile | :)

There is no way to reliably tell. All classes in the .NET Framework are "user defined".

hi,

if you write the classes you can use Attribute elements to determinate it.

You could get the assembly attributes at runtime and check the publisher's name and or copyright notice for 'Microsoft'. Obviously this is not rock solid, but if you want that, the only verifiable way I can think of at the moment is to build a dictionary of all the .NET assemblies and their hash digests (See Assembly.Evidence), then verify the assembly against your dictionary. Not pretty.

I'm trying to get the Unique Serial Number of an SD (Secure Digital) Memory Card, I know how to get the volume information and the like. From reading the specification for the SD Card, I do know each has such an Unique ID. After doing many search here, google, and other web sites I haven't been able to find the answer.

I want the code in c#

Thanks as always for any help you can provide
