The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Converting XML and Hex..

Asked by sterankin in C# Programming Language, .NET

Tags: c#

I am writing a program to open an XML document content which is located as a field a the SQl server DB (stored as ).

I retreive the data from the DB, then convert it to a string using this line:
xmlText = System.Text.Encoding.ASCII.GetString((byte[])rdr[0]);

I then replace part of the XML text with some different text.
I then want to insert the resulting changed text back into the DB.
First I convert it to a byte array:
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
byte[] bytestxt = encoding.GetBytes(xmlText);

The convert it to HEX:
string bytesStr = "0x" + BitConverter.ToString(bytestxt).Replace("-", string.Empty);

And insert it back to the database.

PROBLEM: It works fine, except the last 6 characters on the XML are missing from the XML document, and I cant work out why.
At this point:
xmlText = System.Text.Encoding.ASCII.GetString((byte[])rdr[0]);
the text is complete as I put it in a text box to check.

So it must be somewhere between converting to a byte array and then to HEX.

Any ideas why the last 6 characters are missing?
