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!

Dynamic form not displaying query

Asked by OrionPMS in Delphi Programming

Tags: delphi, dynamic, form, query

I have a dynamically created form, which displays multiple controls linked to a TQuery which is opened prior to the form being created. Everything works fine for the first time the form is displayed, but on the second or subsequent displays of the form, no data is shown! The Query is closed after each form display, and then the form is freed but then each is recreated the second time exactly as the first but without success. The form being opened has nil as the creator. The operation of the Tquery is perfect the first time, with edits being successful etc. Second time, all controls are blank!

The dynamic form shows fields which are linked to a datasource, which itself is a detail table of the main table on the static main form... eg, master record is a client record, itself the result of a Tquery, the detail table which is giving the problems contains assessment records for that client. The linking field is a simple unique serial number, from an integer field. We do not use Delphi Mastersource/Field at all.

My question is why should the dynamic form not display the Tquery results the second time?
