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!

Hooking WM_SYSCOMMAND in a C# winform app; not necessarily active application.

Asked by seeflat in C# Programming Language

Tags: sc_screensave, wm_syscommand

I have created a C# Winform that runs in the systray, has no task bar presence, etc. It registers a bunch of hotkeys so I can do stuff inside the app whether it is the active app or not (using user32.dll RegisterHotKey function)
The application itself runs beautifully, no problems.

However, I am now trying to detect when the user has gone idle. I know this can be accomplished by catching the WM_SYSCOMMAND message and testing for the WParam of SC_SCREENSAVE.
I've actually got this to work, but only if the application is active, and not minimized in the systray.

My question:
"Is there a function (in User32.dll?) to register my application as a listener for SC_SCREENSAVE, kind of like RegisterHotKey (User32.dll) does?"

Thanks,
seeflat
