Summary: riched20 : CRichEditCtrl::LineFromChar does not return
                    correct value
           Product: Wine
           Version: 0.9.19.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-richedit
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I used the function CRichEditCtrl::LineFromChar in an application to get the 
line number in a rich edit control. The function does not return the correct 
value.

In the attached sample application, if the user types in some text in the rich 
edit control, and clicks on any line, a messagebox box is displayed which 
shows the line number in which the user clicked. Under Wine, the messagebox 
always shows 0.
