problem in conversion of binary data to string data

karthi vimala

15y3.7k.NET

hi,

when i insert the word file to the table i convert in to the binary data and then insert it now i want to retrieve the data and convert it into a string in a readable format,

already i used coding like this :System.Text.ASCIIEncoding.ASCII.GetString(bytes) but it didn't work.

when i retrieve the binary data using filestream and display in a word file i got a correct answer in this i used word.application class.

but now i want to display in a notepad or in a noraml webpage.but it wont work can anyone tell me how can i got the result

Thanks

It is just not clear what it is that you really need to do. Sometimes developers try to solve a problem and they think they have a solution so they ask for help with the solution. That is a problem if the solution does not solve the fundamental problem.

It is not clear what you really need to do. Do you need to show only the text without the formatting or do you need to show the formatted text. There are other questions such as that that are not clear.

I am not trying to help because it is not clear what needs to be done. I think that all the other members could help if the problem was adequately explained. Instead of trying to explain it from a programmer's point of view, try to explain it in non-technical terms from the point of view of a user; what is it that a user would expect to happen?

Karthi, Try to understand the situation. You are converting a word format (.doc) into a text format (.txt). Both the format structures are different. You are converting and inserting physical .doc file into DB table, not the contents from that file. The solution for this, open and read only the data/contents from .doc file and then insert into DB table not the file. Later retrieve the data and show it in a notepad. I think the same problem occurred for another member (Kruthika) here.

Well, the problem is that the byte array contains an MS Word document and there's no easy way to convert that to plain text in .NET.

If you could save the Word Document in .RTF format instead, then it would be possible to load it into a RichTextBox and get the plain text from there.

It's also possible for Wordpad to read .RTF files directly though not, of course, Notepad.

What Vulpes said is the important part. You probably need to get the correct encoding for the data and no one can tell you what is correct; it depends on your data.

When you say "some boxes" do you mean that all the data is shown as boxes or do you mean that some text is correct but some is not?

Hi,

Can you share the code so that we can resolve your problem.

The chances are that you're using the wrong encoding to do the conversion.

If for example the binary data is encoded in UTF-8 format, you can get the string equivalent with:

using System.Text;

// ....

string text = Encoding.UTF8.GetString(byteArray);
