AcDbTextStyleTable *pTextTbl;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pTextTbl, AcDb::kForWrite);
AcDbObjectId recId;
pTextTbl->getAt("仿宋_GB2312",recId);
pTextTbl->close();
pText->setTextStyle(recId);
/////////////////////////////////////////////////////////////
pText->setHeight(3.0);
pText->setWidthFactor(0.7);
pText->setPosition(pt);
//pText->setHorizontalMode(AcDb::kTextMid);//设置文本对齐方式
pText->setTextString(GetWeather(sName[n]));
AcDbObjectId textId;
addToModelSpace(textId,pText);//写应力数 Acad::ErrorStatus addToModelSpace(AcDbObjectId &objId, AcDbEntity* pEntity)

AcDb::kForWrite); pSpaceRecord->appendAcDbEntity(objId, pEntity); pBlockTable->close();
pEntity->close();
pSpaceRecord->close();
return es;
}

按照楼上的指点，写出如下的代码，可屏幕输出却是??????!,我觉得可能还是没有 没有应用中文字体，那么应该如何改呢，错误在哪？请继续指点！！！！ void settextstyle(AcDbText *pText) //参数为AcDbText *&pText也一样
{
AcGePoint3d startpoint(500,500,0);
AcDbTextStyleTable *pTextTbl;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pTextTbl, AcDb::kForWrite);
AcDbObjectId recId;
pTextTbl->getAt("仿宋_GB2312",recId);
pTextTbl->close();
pText->setTextStyle(recId);
pText->setHeight(3.0);
pText->setWidthFactor(0.7);
pText->setPosition(startpoint);
pText->setHorizontalMode(AcDb::kTextMid);//设置文本对齐方式
pText->setTextString("这是一个测试!");
} void drawtext()
{
AcDbText* ptextout=new AcDbText();
settextstyle(ptextout);
AcDbBlockTable *pblocktable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pblocktable,AcDb::kForWrite);
AcDbBlockTableRecord *pblockrecord;
pblocktable->getAt(ACDB_MODEL_SPACE,pblockrecord,AcDb::kForWrite);
pblocktable->close();
AcDbObjectId id;
pblockrecord->appendAcDbEntity(id,ptextout);
pblockrecord->close();
ptextout->close();
}
