In practice (so long as the number and extent of conflicts are limited) automatic conflict resolution may be used to good effect to correct problems without undue amounts of programmer intervention.</P ><P >In order to select the conflicts to be applied, select or clear the check boxes against the resolutions for each proposed resolution. By default all resolutions are selected; you can return to the default state (in other words, cause all check boxes for each conflict to again become checked) by pressing the “Reset” button. Note that multiple selection may be used in the resolutions control to allow ranges of check boxes to be toggled in one gesture.</P ><P >When you are happy to apply the selected resolutions for each conflict displayed, click <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >Apply</I ></SPAN >; this will apply the resolutions. Alternatively you may cancel from the dialog box without any resolutions being applied.</P ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="config-tool-platform-selection.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ecos-user-guide.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="config-tool-searching.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Platform Selection</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="config-tool-updating-configuration.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Searching</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
