[求助]arx的反应器问题
<p>请教各位高手：</p><p>ARX中的反应器是否跟VBA中的事件是一个功能，其中的那个函数与VB中的BeginCommand对应？是CommandWillStart么？如果是又该怎么用呢？它与ObjectErase（）有什么区别呢？我的目的就是捕捉AutoCAD的命令，好进一步处理！</p><p>小妹刚学ARX不久，此问题已找了两天，帮助文件读了不是很懂！哪位高手指点指点！please...</p><p>先谢谢了！</p> 本帖最后由 作者 于 2008-3-17 12:16:50 编辑 <br /><br /> <p>还有MM搞CAD开发，少见~~</p><p class="signature">virtual void</p><p class="signature">commandWillStart(</p><p class="signatureInEnd">const char* cmdStr);</p><p><table class="argumentList"><tbody><tr valign="baseline"><td class="argumentName">cmdStr</td><td class="argumentDescription">Passed in string of the command being executed</td></tr></tbody></table></p><p>This callback function indicates that the command cmdStr is about to begin execution.</p><p>cmdStr may be up to 257 characters (including the string terminator).</p><p>这个反应器是指命令启动前调用的。是编辑环境里用的</p><p>和那个VBA是一样的</p><p>ObjectErase 是AcDataBase里用的</p><p></p><p><a href="javascript:toggleproc( proc0, proc0img, 'PROC0' );" style="TEXT-DECORATION: none;"><img id="proc0img" src="mk:@MSITStore:D:\Program%20Files\objectarx2002\docs\arxref.chm::/Images/ac.down.gif" border="0" alt=""/> AcEditorReactor Command-Related Functions</a><table cellpadding="6"><tbody><tr><td> </td><td class="functionLinks"><a href="mk:@MSITStore:D:\Program%20Files\objectarx2002\docs\arxref.chm::/AcEd/AcEditorReactor/commandCancelled.htm">commandCancelled</a>

谢谢！
<p>呵呵！我也没办法！不过谢谢你，可是我还想问一下AcDataBase和AcEditorReactor有什么区别？如果我是要对用户删除直线命令作出反应，应该用哪一个？我还得将用户删除的直线同步删除SQL Serve2000 中的数据，请问是否是捕捉选择集中的数据？再次感谢了！</p><p></p> <p>我想该用AcDbObjectReactor这个类的</p><p><a href="javascript:toggleproc( proc1, proc1img, 'PROC1' );" style="TEXT-DECORATION: none;"><img id="proc1img" src="mk:@MSITStore:D:\Program%20Files\objectarx2002\docs\arxref.chm::/Images/ac.down.gif" border="0" alt=""/> AcDbObjectReactor Notification Functions</a><p><table cellpadding="6"><tbody><tr><td> </td><td class="functionLinks"><a href="mk:@MSITStore:D:\Program%20Files\objectarx2002\docs\arxref.chm::/AcDb/AcDbObjectReactor/cancelled.htm">cancelled</a>
