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!

Query refresh?

Zones: Delphi Database, Delphi Programming

Hi, I have this issue.

Two PCs, one acts as a server for data, the second as client.
One application that use through an alias the same data.

I use Database and Session components.
Alias and NetFileDir points to \\Server\Data.
Queries and Tables have AutoRefresh setting to TRUE.
On every AfterPost event i do this to ensure data is written to disk.
Table.UpdateCursorPos;
DbiSaveChanges(Table.Handle);
Table.CursorPosChanged;

Some changes made to the data in one PC is not refreshed to the other PC.
What is more, data is not refreshed for queries (that calculates in the moment and after the changes was posted).

If i manually refresh a TTable based on the same tablename as the query, it shows me the new data. As an example of this. Without the table refresh, the results of the query do not show the new data, dispite "there is no" relation between table cursor and query from clause.
Table1.Refresh;
Query1.SQL.Text := 'SELECT * FROM ' + Table1.TableName;
Query1.Open;

Try to add to the code above a Table.Refresh line of code, but its do nothing as it runs in the same PC that makes the changes.

Is there a way to avoid a manual refresh of every table?
