试图更改CAD文件中数字标注内容时出错（附源码）
试图更改CAD文件中数字标注内容时出错,源码如下：//打开数据库
AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable,AcDb::kForWrite);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
pBlockTable->close();
AfxMessageBox("open model space");
//创建块表记录遍历器，用遍历器遍历实体，并修改标注值。
AcDbRotatedDimension *pDimention;
char* Texttemp;
ACHAR* Astr;
Astr="111";
AcDbBlockTableRecordIterator *pBlockIterator;
pBlockTableRecord->newIterator(pBlockIterator);
for(pBlockIterator->start();!pBlockIterator->done();pBlockIterator->step())
{
AcDbEntity *pEntity;
pBlockIterator->getEntity(pEntity,AcDb::kForWrite);
const char *pCname=pEntity->isA()->name();
if(strcmp(pCname,"AcDbRotatedDimension")==0)
{
pDimention=AcDbRotatedDimension::cast(pEntity);
Texttemp=pDimention->dimensionText();
if(strcmp(Texttemp,"e")==0)
{
AfxMessageBox("found linedim");
pDimention->setDimensionText(Astr);
}
}
}
delete pBlockIterator;
pBlockTableRecord->close();
出错提示：内部错误：
是不是CAD文件在打开时，不能用ARX修改实体。
期盼高手指点！！！
**** Hidden Message ***** 搞定了，实体没有关闭的缘故 thank you
