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!

Thead creation in View class

Asked by mrwad99 in Windows MFC Programming

Tags: thead

Ah hello.

I am creating a thread in the view class of my MDI app.  Now this CWinThread* object is a member of the view class.  I create the thread suspended in a handler for one of my menu items, set its autodelete member to FALSE, then resume the thread.  I delete the thread in the destructor for my view.

I pass to the thread function a custom struct containing information that the thread will need.  This is created on the heap with new to avoid it going out of scope.

In the thread function, I cast the parameter back to my custom structure:

UINT CMyView::ThreadFunc(LPVOID pParam)
{      
      THREADPARAMS* pTp = (THREADPARAMS*)pParam;
                // do stuff
                delete pTp;
}

Now the problem.  I am concerned if the "do stuff" takes a long time to complete, and the user chooses to close the app before delete pTp can be called, I will suffer memory leaks.

How can I prevent this ?

TIA
