Hi everyone!

I'm coding for Insert Block from file DWG to Current Drawing autocad. But error.

anyone Modify my code

Thanks

void Block()
{
ACHAR* szName = _T("luanuoc");
ACHAR *fileName = _T("C:\\procad\\dwg\\luanuoc.dwg");
AcDbDatabase *pDb = acdbHostApplicationServices()->workingDatabase();
AcDbDatabase *pBlockDb = new AcDbDatabase(false,true);
pBlockDb ->readDwgFile(fileName,_SH_DENYRW,true);
AcDbBlockTable *BlkTable;
AcDbObjectId BlkId;
//AcDbObjectIdArray Ids = new AcDbObjectIdArray();
//BlkId =pBlockDb ->blockTableId();
BlkTable ->getAt(ACDB_MODEL_SPACE,BlkId,AcDb::kForRead);
pDb->insert(BlkId,szName,pBlockDb,true);
if (BlkTable->has(BlkId))
{
ads_point p;

acedGetPoint(NULL,"Chon diem chen",p);
AcGePoint3d Inspoint(p[X],p[Y],p[Z]);
AcDbBlockReference *pBlockobj = new AcDbBlockReference;
AcDbBlockTableRecord *pBlkTablerec;
pBlockobj ->setBlockTableRecord(BlkId);
pBlockobj ->setPosition(Inspoint);
pBlockobj ->setScaleFactors(1);
BlkTable ->getAt(ACDB_MODEL_SPACE,pBlkTablerec,AcDb::kForWrite);
BlkTable ->close();
pBlkTablerec ->appendAcDbEntity(pBlockobj);
pBlkTablerec ->close();
pBlockobj ->close();


}
}

What is the error?

[#3]

Error Insert Block. Can you help me?

[#4]

Sorry, I don't understand what the problem is.

Owen asked you about error code. IMHO it is a Fatal Error because of using non-initialize variable BlkTable in line:

BlkTable ->getAt(ACDB_MODEL_SPACE,BlkId,AcDb::kForRead);

Thanks, I fixed this error.

But I have this code for create Block with two Attributes. Then Insert this Block into drawing.

But erro they missing Attributes when i insertBlock:

1. I use Function TaoBLKDCC2 for create Block and add to Database( this very good)

2. Then Use function InsertKH1 for Insert Block with name DCC21 into Drawing with two Attributes( this function error, not have attributes

Can you help me? thank very much!

You forgot after creation AcDbBlockReference add all AcDbAttribute's to it (with help of AcDbAttribute::setAttributeFromBlock method)

I Fixed this error.

Thank you very much.
