新建图层“选址标注”；当鼠标点击屏幕位置（鼠标事件的响应？）时在点击位置标注内容：“建设项目选址意见书[5字]”
哪位高手帮忙 回个话 做不了我可就完蛋了
现在已经完成了新建图层：
void createnewlayer(const cstring layername, const int color)
{ acdblayertable *playertbl;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(playertbl, acdb::kforwrite);
//获得当前层表以便写入
if (!playertbl->has(layername)) {
acdblayertablerecord *playertblrcd
= new acdblayertablerecord;
playertblrcd->setname(layername);
playertblrcd->setisfrozen(0);// layer to thawed解冻图层
playertblrcd->setisoff(0); // layer to on 打开图层
playertblrcd->setvpdflt(0); // viewport default视口默认值
playertblrcd->setislocked(0);// un-locked 解锁图层
accmcolor color1;
color1.setcolorindex(color); // set color to color
playertblrcd->setcolor(color1);
acdblinetypetable *plinetypetbl;
acdbobjectid ltid;
acdbhostapplicationservices()->workingdatabase()
->getsymboltable(plinetypetbl, acdb::kforread);
if ((plinetypetbl->getat("continuous", ltid))
!= acad::eok)
{
acutprintf("\nunable to find continuous"
" linetype. using dashed");
plinetypetbl->getat("continuous", ltid);
}
plinetypetbl->close();//设置线型
playertblrcd->setlinetypeobjectid(ltid);
playertbl->add(playertblrcd); //将层表记录添加到层表中！
playertblrcd->close();//关闭层表记录
playertbl->close();//关闭层表
} else {
playertbl->close();
acutprintf("\n图层已经存在！");
}
/*
acdb::lineweight lw; //设置层的线宽
lw = acdb::klnwt080; //value:80
playertablerecord->setlineweight(lw);
*/
}

朋友给了段带码很管用，但是遇到两个问题：
1。文章是中文的时候出现乱码？
2。不知道如何设坐标点（下面的代码是坐标点已知的），使得在鼠标点击屏幕位置（鼠标事件的响应？）时的点击位置标注内容？
void addtext( char textstring[512])
{

acdbblocktable *pblocktablew;
acdbhostapplicationservices()->workingdatabase()->getsymboltable(pblocktablew, acdb::kforread);
acdbblocktablerecord *pblocktablerecordw;
pblocktablew->getat(acdb_model_space, pblocktablerecordw, acdb::kforwrite);
pblocktablew->close();
acgepoint3d textposition(10.0, 10.0, 0.0);
acgepoint3d atextposition(20.0, 10.0, 0.0);
//char textstring[512] = "建设项目选址意见书[5字] 号红线附图";
double textheight = 5.5296;
double textwidthfactor = 0.8000;
double textrotation = 0.0;
acdbtext *ptext=new acdbtext(textposition, textstring, acdbobjectid::knull, textheight, textrotation);
ptext->sethorizontalmode(acdb::ktextmid);
ptext->setalignmentpoint(atextposition);
acdbobjectid textid;
pblocktablerecordw->appendacdbentity(textid, ptext);
pblocktablerecordw->close();
ptext->close();
}
我也想知道，帮你顶

谢谢这位朋友的关注 问题都已解决，给出代码如下：

//准备开始文字注记
acdbblocktable *pblocktablew;
acdbhostapplicationservices()->workingdatabase()

acdbblocktablerecord *pblocktablerecordw;
pblocktablew->getat(acdb_model_space,
pblocktablerecordw, acdb::kforwrite);
acdbdatabase *pdb = acdbhostapplicationservices()->workingdatabase ();
acad::errorstatus es; //打开数据库->块表->块表记录
es = pdb->getblocktable (pblocktablew,acdb::kforread );
// error handle
es = pblocktablew->getat (acdb_model_space,pblocktablerecordw,acdb::kforwrite );
acdbtextstyletable *ptst;
acdbtextstyletablerecord *ptstr;
es = pdb->gettextstyletable (ptst,acdb::kforread );
//文字样式表-〉文字样式表记录-〉打开记录读取
acdbobjectid idtextstyle;
es = ptst->getat("standard",idtextstyle);
es = ptst->getat("standard",ptstr,acdb::kforwrite );
ptstr->setfilename("hztxt");//****
if(es != acad::eok){
acutprintf("fail to get the standard text style\n");
}
