[求助]：如何将DWG中的文字批量更改

yuleyue

由于要将DWG文件中N多的文字进行翻译, 想到了先将所有的文字全部导出到一文本文件中(已实现,代码如下)

//导出DWG文件中的文字串

void CTransTextDlg::OnBtExportText()
{
// TOD Add your control notification handler code here
AcDbDatabase* pDb;
AcDbBlockTable *pBlockTable;
pDb = acdbHostApplicationServices()->workingDatabase();
pDb->getSymbolTable(pBlockTable, AcDb::kForRead);

AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForRead);
pBlockTable->close();

AcDbBlockTableRecordIterator *pBlockIterator;
pBlockTableRecord->newIterator(pBlockIterator);

//打开文件用于输出
CString szFilter=_T("Data Files (*.dat;*.txt)|*.dat; *.txt|All Files (*.*)|*.*||");
CString szDefExt(_T(".DAT"));
CAcUiFileDialog dlg(FALSE, szDefExt, NULL,
OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter);
dlg.DoModal();
CString strFileName;
strFileName = dlg.GetFileName();
ofstream out(strFileName);
if(!out)
{
MessageBox("指定导出文件无法打开!");
return;
}

//设置计数器
LONG lCounts = 0;
for (; !pBlockIterator->done(); pBlockIterator->step())
{
AcDbEntity *pEntity;
pBlockIterator->getEntity(pEntity, AcDb::kForRead);

const char *pCname = pEntity->isA()->name();

if(!strcmp(pCname, "AcDbText")) //是单行文字类
{
//获取文字内容
lCounts++;
const char *pText = ((AcDbText*)pEntity)->textString();
out<objectId()<<",\t"< }
else if(!strcmp(pCname, "AcDbMText")) //是多行文字类
{
lCounts++;
const char *pMText = ((AcDbMText*)pEntity)->contents();
out<objectId()<<",\t"< if(pMText)
pMText = NULL;
}
pEntity->close();
}
out.close();
delete pBlockIterator;
pBlockTableRecord->close();
}

翻译后欲重新导入原DWG文件中, 如下:

void CTransTextDlg::OnBtSubsTexts()
{
// TOD Add your control notification handler code here
//打开文件用于输出
AcDbDatabase* pDb;
AcDbBlockTable *pBlockTable;
pDb = acdbHostApplicationServices()->workingDatabase();
pDb->getBlockTable(pBlockTable, AcDb::kForRead);

AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForRead);
pBlockTable->close();
AcDbBlockTableRecordIterator *pBlockIterator;
pBlockTableRecord->newIterator(pBlockIterator);


CString szFilter=_T("Data Files (*.dat;*.txt)|*.dat; *.txt|All Files (*.*)|*.*||");
CString szDefExt(_T(".DAT"));
CAcUiFileDialog dlg(TRUE, szDefExt, NULL,
OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter);
dlg.DoModal();
CString strFileName;
strFileName = dlg.GetFileName();
ifstream in(strFileName);
if(!in)
{
MessageBox("指定导入文件无法打开!");
return;
}

//设置计数器
LONG lCounts = 0;
LONG lID;
for (; !pBlockIterator->done(); pBlockIterator->step())
{
AcDbEntity *pEntity;

Acad::ErrorStatus es;
es = pBlockIterator->getEntity(pEntity, AcDb::kForRead);
switch(es)
{
case Acad::eOk:
acutPrintf("Acad::eOk\n");
break;
case Acad::ePermanentlyErased:
acutPrintf("Acad::ePermanentlyErased\n");
break;
case Acad::eAtMaxReaders:
acutPrintf("Acad::eAtMaxReaders\n");
break;
case Acad::eWasOpenForNotify:
acutPrintf("Acad::eWasOpenForNotify\n");
break;
case Acad::eWasNotifying:
acutPrintf("Acad::eWasNotifying\n");
break;
case Acad::eWasOpenForUnd
acutPrintf("Acad::eWasOpenForUndo\n");
break;
case Acad::eWasOpenForWrite:
acutPrintf("Acad::eWasOpenForWrite\n");
break;
case Acad::eWasOpenForRead:
acutPrintf("Acad::eWasOpenForRead\n");
break;
default:
acutPrintf("Unknown error type.\n");
break;
}

const char *pCname = pEntity->isA()->name();

if(!strcmp(pCname, "AcDbText")) //是单行文字类
{
//获取文字内容
acutPrintf("Step -- %ld\n", 4+lCounts);
lCounts++;
char inStr[256];
in>>lID>>inStr;
((AcDbText*)pEntity)->setTextString(inStr);
}
else if(!strcmp(pCname, "AcDbMText")) //是多行文字类
{
lCounts++;
char inStr[1024];
in>>lID>>inStr;
((AcDbMText*)pEntity)->setContents(inStr);
}
pEntity->close();
}
in.close();
delete pBlockIterator;
pBlockTableRecord->close();
}

可却有错! 请教了!!!

两种方式“
1，导出实体的handle，通过handle的对应关系进行导入。
2，在实体上添加信息，可以是xdata或者xrecord，然后根据添加的信息进行对应的导入导出。

谢谢了,第一种方式中,是否如下:
void XXX
{
        char handleStr[20];                                                //句柄串
        char newText[1024];                                                //新字串
        ads_name entres;                                                //
    AcDbEntity* pEnt;                                                //
    AcDbObjectId objId;
        ifstream in("XXXX");                                        //包含编辑后内容的文本, 顺序与导出时一致
        while(!in.eof())
        {
                in>>handleStr>>newText;                                //从打开的文本文件流中导入上述二字串
                acdbHandEnt(handleStr, entres);                //找到实体名
                acdbGetObjectId(objId, entres);                //根据实体名找到ID
                acdbOpenAcDbEntity(pEnt, objId, Acad::eForWrite);                //打开ID所对应的实体用于写操作

                const char *pCname = pEnt->isA()->name();                //实体所属类名

                if(!strcmp(pCname, "AcDbText"))        //单行文字类
                {
                        ((AcDbText*)pEnt)->setTextString(newText);        //替换原有字串
                }
                if(!strcmp(pCname, "AcDbMText"))        //多行文字类
                {
                        ((AcDbMText*)pEnt)->setContents(newText);        //替换原有字串
                }
                pEnt->close();
        }
        in.close();
}

还有一种方法，用长事务类可以实现，并且留下bak文件。
