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!

Tooltips: tracking and working for disabled controls - how?

Asked by mrwad99 in Windows MFC Programming, Windows Programming

Ah hello.

I have a very simple dialog application, and am trying to accomplish two tasks with tooltips:

1 ) Get the tooltip to track with the mouse movement,i.e. follow the mouse cursor around, as long as it remains on the same control.
2) Get the tooltip to appear on a disabled control.

I have uploaded my simple project (VS2003, for maximum compatibility :)) to http://www.yousendit.com/download/bVlBWGJDd0lCSWRFQlE9PQ, please download it and take a look.

FYI, here is the code I am using to create and display the tooltip:

BOOL CEE_Tooltip_QDlg::OnInitDialog()
{
      CDialog::OnInitDialog();

      VERIFY ( m_wndTooltip.Create ( this ) );

      VERIFY ( m_wndTooltip.AddTool ( GetDlgItem ( IDC_MYCONTROL ), LPSTR_TEXTCALLBACK ) );
      VERIFY ( m_wndTooltip.AddTool ( GetDlgItem ( IDC_EDIT1 ), LPSTR_TEXTCALLBACK ) ); // Disabled edit control

      // ...
}

void CEE_Tooltip_QDlg::OnNeedText ( NMHDR* pnmh, LRESULT* pResult )
{
      TOOLTIPTEXT* pttt = ( TOOLTIPTEXT* ) pnmh;
      // If the tooltip that this message has been sent for is our tooltip...
      if ( pttt->hdr.hwndFrom == m_wndTooltip.m_hWnd )
      {
            // Find the string that maps to the window we are displaying the tooltip for ( stored in pttt->hdr.idFrom ).
            m_strTooltipText = _T("This is a long tooltip that has come from CEE_Tooltip_QDlg::OnNeedText");
            pttt->lpszText = ( LPTSTR ) ( LPCTSTR ) m_strTooltipText;
      }
}

Can someone please tell me how to achieve these two tasks?  I simply cannot find anything on the internet about this.
