请高手指点一二！

struct point <br>
{double x,y,z;<br>
};<br>
int fk(point &amp;ptMin, point &amp;ptMax)<br>
{&nbsp;&nbsp; &nbsp;AcApDocManager *acDocManager;<br>
&nbsp;&nbsp; &nbsp;AcApDocument* pDoc = acDocManager-&gt;curDocument();<br>
&nbsp;&nbsp; &nbsp;acDocManager-&gt;lockDocument(pDoc);<br>
&nbsp;&nbsp;&nbsp; ads_point pt1,pt2;<br>
&nbsp;&nbsp; &nbsp;acedGetPoint(NULL,"Ñ¡¶¨×°ÔØ·¶Î§: ", pt1 );<br>
&nbsp;&nbsp; &nbsp;if(acedGetCorner(pt1,NULL,pt2)==RTCAN) return 0;<br>
<br>
&nbsp;&nbsp; &nbsp;if(pt1&lt;=pt2){ptMin.x=pt1;ptMax.x=pt2;}<br>
&nbsp;&nbsp; &nbsp;else{ptMin.x=pt2;pMax.x=pt1;}<br>
&nbsp;&nbsp; &nbsp;if(pt1&lt;=pt2) {ptMin.y=pt1;ptMax.y=pt2;}<br>
&nbsp;&nbsp; &nbsp;else{ptMin.y=pt2;ptMax.y=pt1;}<br>
&nbsp;&nbsp; &nbsp;acutPrintf("Ñ¡¶¨ptMin, ptMax)%f&nbsp; %f&nbsp;&nbsp;
%f&nbsp; %f&nbsp; \n",ptMin.x,ptMin.y ,ptMax.x,ptMax.y );<br>
&nbsp;&nbsp; &nbsp;acDocManager-&gt;unlockDocument(pDoc);<br>
<br>
&nbsp;&nbsp; &nbsp;return 1;<br>
<br>
}<br>
<br>
void :inifk()<br>
{<br>
&nbsp;&nbsp; &nbsp;AcApDocManager *acDocManager;<br>
&nbsp;&nbsp; &nbsp;AcApDocument* pDoc = acDocManager-&gt;curDocument();<br>
&nbsp;&nbsp; &nbsp;acDocManager-&gt;lockDocument(pDoc);<br>
&nbsp;&nbsp; &nbsp;CString tmp,strtmp;<br>
&nbsp;&nbsp; &nbsp;strtmp+="zoom ";;<br>
&nbsp;&nbsp; &nbsp;tmp.Format("%-10.4lf",pMin.x);<br>
&nbsp;&nbsp; &nbsp;strtmp+=tmp;strtmp+=",";<br>
&nbsp;&nbsp; &nbsp;tmp.Format("%-10.4lf",pMin.y);<br>
&nbsp;&nbsp; &nbsp;strtmp+=tmp;<br>
&nbsp;&nbsp; &nbsp;tmp.Format("%-10.4lf",pMax.x);<br>
&nbsp;&nbsp; &nbsp;strtmp+=tmp;strtmp+=",";<br>
&nbsp;&nbsp; &nbsp;tmp.Format("%-10.4lf",pMax.y);<br>
&nbsp;&nbsp; &nbsp;strtmp+=tmp;strtmp+=" ";<br>
//AfxMessageBox(strtmp);<br>
&nbsp;&nbsp; &nbsp;acDocManager-&gt;sendStringToExecute(pDoc,strtmp,true,false,true);<br>
&nbsp;&nbsp; &nbsp;acDocManager-&gt;unlockDocument(pDoc);<br>
<br>
<br>
}<br>
inifk();//初始化绘图范围<br>
fk();//选择小部分绘图范围<br>
两个函数连续执行有点问题<br>
单个执行都没有问题。请高手指点一二！<br>

<P>请教第一个问题：定义这个struct point有什么意义。</P>
<P>在ObjectARX中或者用ads_point，或者用AcGePoint3d类(gepnt3d.h )、AcGePoint2d类(gepnt2d.h)，有现成的东东最好拿来用，因为其比较完善。</P>
<P>而且有现成的转换函数(geassign.h )：</P>
<P>double * asDblArray(const AcGePoint3d&amp; pnt);</P>
<P>AcGePoint2d &amp; asPnt2d(const double* pnt);</P>
<P>AcGePoint3d &amp; asPnt3d(const double* pnt);</P>
<P>第二，函数 inifk()中变量pMin没有定义。<BR></P>

<P>inifk();//初始化绘图范围<BR>fk();//选择小部分绘图范围</P>
<P>这两个函数的现实意义或你的设想？</P>

问题关键不在与 STRUCT POINT 关键在于acDocManager-&gt;sendStringToExecute(pDoc,strtmp,true,false,true);执行后，再执行FK（），结果是先执行ＦＫ（），不能够按原来的设计执行。<br>
请高手联编执行一下。<br>
inifk();目的就是先将当前绘图区设置好。fk()　　当前绘图区选择部分区域。<br>
