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.

Thank you!

Spying on a DLL

Asked by heathprovost in Delphi Programming

Hello all!  I have a problem.  I have a 2 DLLs for which I have no source code.  One of the DLLs does nothing but implement a dialog box that calls some functions in the other DLL.  I have heard that it is possible to write a DLL which does nothing but pass calls along to another DLL.  What I want to do is create a DLL that will spit out the bits that are getting passed to the DLL i am "spying" on and then return the results to the calling program.  The problem is since I dont have the source code, I dont have the parameters for the functions, only the names.  Is this possible and how should I approach it.

btw - the two DLLs are Windows System files which implemet the Dial-Up Server.  I am trying to develop a way to interact with it from a programic level (like you can in NT with the RasAdmin API calls).

Any help would be appreciated.  If I ever get this thing working I will make it publicly available, but need it for a project I am working on.
