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.

Display BLOB by ASP

Zones: Oracle 3rd Party Tools, Oracle Database

We want to run ASP page to display some records w/ picture (BLOB) from Oracle 10g database. And just found some sample coding, that is worked for picuter display. But when I change it something like that..

Sample table
A Varchar(10)
B Varchar(20)
IMG BLOB

...
sSQL = "Select A, B, IMG from IMAGE where A = "testing"
...
oRS.Open

strtemp = oRS("IMG")
Response.BinaryWrite(strTemp)

strtemp2 = oRS("A") <---- new add
Response.Write(strTemp2) <---- new add

Response.End
....

It has an error, any wrong ? Those code is good for BLOB only ? I MUST display all (include text and picture together) from database.

Can help please ?

Thanks !
