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!

How to skip Formshow when I set a tForm Visible?

Asked by Treppenmeister in Delphi Programming

Tags: formshow

I have a Form with several controls. Because of several reasons I am rearranging all the components on the form while the program is running. Unfortunately this has the effect, that the more controls I am changing and the slower the machine is the easier I can see the 'moving' and the form is flickering. So I want to do the changes in the background.
When I had similar problems with drawing into a drawbox I just used the Visible-property.

So I tried this also here

Form.Visible := false;
RearrangingMyControls;
Form.Visible := true;

unfortunately the last one is calling the FormShow, what I cannot need.
Now I could override the Visible property and set a variable SkipFormShow : boolean to control that. But then I have to write in every Form at the beginning of every FormShow procedure a line like

if SkipFormShow then exit;

I have my own class tMyForm of tForm. But all what I tried, to control from there, whether to jump into the childs FormShow or not, failed.

What is the easiest way to have the logic in my basic class tMyForm?
