一个关于:vlax-false问题
<p><font size="4">（setq layer_ob "0"） ，我想用(vla-get-Freeze layer_ob)判断＂0＂层是否是冻结状态，如果是冻结，就将其解冻，否则就它冻结． 但是程序在运行确老是错误，我知道应该是 (if (= (vla-get-Freeze layer_ob) :vlax-false) 这句错了，但不知道怎么改？请高手指点！</font></p><p><font size="4"> (if (= (vla-get-Freeze layer_ob) :vlax-false) <br/> (vla-put-Freeze layer_ob -1)<br/> (vla-put-Freeze layer_ob 0)<br/> )</font></p> <p>Check here:<br/><a href="http://forums.augi.com/archive/index.php/t-8848.html">http://forums.augi.com/archive/index.php/t-8848.html</a></p><p><a href="http://forums.augi.com/archive/index.php/t-8848.html"></a></p> <p>Check here:<br/><a href="http://forums.augi.com/archive/index.php/t-8848.html">http://forums.augi.com/archive/index.php/t-8848.html</a></p><p><a href="http://forums.augi.com/archive/index.php/t-8848.html"></a></p> 在冻结图层时候,先判断该图层是否当前层,,,,,, <p><font>(vla-get-Freeze<br/> (vla-item<br/> (vla-get-layers<br/> (vla-get-activedocument (vlax-get-acad-object))<br/> )<br/> layer_ob<br/> )<br/>)</font></p> <p><font size="+0">我是想请教,我这段代码为什么判断不出来</font><font size="4">layer_ob图层是"冻结"还是"解冻"的状态?</font></p><p><font size="4"> (if (= (vla-get-Freeze layer_ob) :vlax-false) <br/> (vla-put-Freeze layer_ob -1)<br/> (vla-put-Freeze layer_ob 0)<br/> )</font></p> <p>你的语法不对，我5楼已经说明了</p><p><font size="4">layer_ob 不应是字符串，而是vla图层集合的索引数据</font></p> <p><strong><font face="Verdana" color="#61b713">我还是不怎么不明白,请求caoyin大哥帮忙写个完整的.</font></strong><strong><font face="Verdana" color="#61b713">我的目的是要判断"dim"尺寸层的状态.如果该层是冻结状态,就将该层解冻,如果是未冻结状态,就将该层冻结.先谢了.拜托</font></strong></p> <p>请自行判断图层状态,此段代码 Freeze "DIM"</p><p>(vla-put-freeze<br/> (vla-item (vla-get-layers<br/> (vla-get-activedocument (vlax-get-acad-object))<br/> )<br/> "Dim"<br/> )<br/> :vlax-true<br/>)<br/>;; or<br/>(vla-put-freeze<br/> (vlax-ename->vla-object (tblobjname "layer" "Dim"))<br/> :vlax-true<br/>)</p>
