[求助]：怎样设置一个图层的线型

zlbzlb

一般图层默认的线型为CONTINUOUS，如果，我想增加一个图层，并将该图层的线型设置为Dashed,线型文件为Acadiso.lin，我应该怎么做？
PS:顺便问一下各位老师，怎样将一个以打开的dwg文件设置为当前工作文件。

我这里假设 图层的名字为 "testLayer"为例子以说明:
void HYTEST()
{
        //        Note: we add the layer's name is 'TestLayer'...
        char layerName[20]="TestLayer";
        //        First ,check the drawing there is or not have the 'DASHED' linetype
        AcDbLinetypeTable *pLinetypeTable;
        acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pLinetypeTable,AcDb::kForRead);
        if(!pLinetypeTable->has("Dashed"))
        {
                acutPrintf("\n**Add linetype 'Dashed'");
                pLinetypeTable->close();
                if(acdbHostApplicationServices()->workingDatabase()->loadLineTypeFile("DASHED","ACADISO.LIN")!=Acad::eOk)
                {
                        acutPrintf("\n**Error on load linetype 'Dashed'...");
                        return;
                }
        }       
        else
                pLinetypeTable->close();
        //        Second        ,add the new layer to the drawing and set the layer linetype to 'Dashed'
        AcDbLayerTable        *pLayerTable;
        AcDbObjectId eId;
        acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pLayerTable,AcDb::kForWrite);
        acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pLinetypeTable,AcDb::kForRead);
        pLinetypeTable->getAt("Dashed",eId);
        pLinetypeTable->close();
        if(pLayerTable->has(layerName))
        {
                acutPrintf("\n**Error,the layer exist...");
                pLayerTable->close();
                return;
        }
        AcDbLayerTableRecord *pNewLayer=new AcDbLayerTableRecord();
        pNewLayer->setName(layerName);
        pNewLayer->setLinetypeObjectId(eId);
        pLayerTable->add(pNewLayer);
        pNewLayer->close();
        pLayerTable->close();
}

1楼说的对阿，怎么才能够实现呢，我编了个小程序也涉及到这方面的问题，由于没办法解决，所以没有实现这个功能
