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.

Is there a way to catch a window focus change event?

Asked by Perkentha1 in Operating Systems Development, X-Windows Window Manager, Windows XP Operating System

Tags: , ,

Short problem expansion:
The page listing http://www.csharphelp.com/archives2/archive301.html shows that you can get the window name of the active window.  This works but the problem i need is to find the application that caused that window to become active, perhaps by watching an event.. which is similar to keylogging yes.. i know.

Problem Description:
On multiple systems at random times the user will loose focus of ALL windows, like they clicked on the desktop.  They have to then click on their app they were in but will continue to loose focus every 10-15 seconds.  The freeky part it seems totaly random.  The user could be in IE.. could be in notepad.. whatever.  It doesn't happen to all the time, so it's hard to test against because it's sparatic and seems random.

Solution Idea...:
I know that by creating a system hook you can track events systemwide,  like mouse clicks in any window.  You can then allow that event to continue down it's normal path or modify the path it takes.  What i'm asking here is... Is there a way to catch the event of a window change prior to it changing so we know where the request came from?  Consider the following super anoying popup to get a better idea.

Example:
User is in notepad typing away.. POPUP says "Application ABC wants to change the window focus to DEF window from XYZ.  Click YES to allow it or NO to abort the focus change".

OMG that would be anoying... but you get the point of what i'm trying to accomplish so we can figure out what and why they focus is being changed/lost.  Oh.. and the solution should be involving C# with dot net 2.0
