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 enlarge components within a PDF file with Delphi 7?

Asked by atdatadevtec in Delphi Programming, Adobe Acrobat, Delphi IDE

Tags: Delphi 7

I have to enlarge a button in a pdf file but I'm not able to set the 'rect' property of it. Its possible to read the coordinates but not to write them even though the property has read/write access.
The strange thing is that it works in VB6.
The code below raises an EOleSysError with message 'wrong parameter'.
I need to do this programmatically because there is a big amount of pdf files stored in a database and all of them have to be updatet.

   rect[0] := ...//some value of type double
   rect[1] := ...//some value of type double
   rect[2] := ...//some value of type double
   rect[3] := ...//some value of type double
 
   mField.rect := rect;//the error occurs here
