Update "Prompt" tab in an existing Block Attribute.

[jlobo]

I need to update the tag, prompt, value tab in the current block attribute.

I can change the tag and the value tab but not the prompt.

 

Any help will be appreciated.

 

 

The approach am taking is;

 

AcDbDatabase *dwgDb;

AcDbBlockTable *pBlockTbl;

AcDbBlockTableRecord *pModelSpaceTblRcd;

AcDbBlockTableRecordIterator *pModelSpaceItr;

AcDbEntity *pEntity;

AcDbBlockReference *pBlockRef;

AcDbAttribute *pAttribute;

AcDbObjectIterator *pAttrItr;

AcDbObject *pObject;

 

TCHAR tagBuffer[sINGLE_LINE_INPUT_LENGTH_SHORT];

 

// Prepare attribute location measurements

 

AcDbObjectId idOfEntity;

 

 

dwgDb = NULL;

dwgDb = acdbHostApplicationServices()->workingDatabase();

if (dwgDb == NULL)

{ AfxMessageBox(_T("Internal Error !"));

return false; }

 

 

dwgDb->getSymbolTable(pBlockTbl, AcDb::kForWrite);

pBlockTbl->getAt(ACDB_MODEL_SPACE, pModelSpaceTblRcd, AcDb::kForWrite);

pBlockTbl->close();

 

 

// Get an iterator to that we can iterate / pinpoint

// the desired entity via the objectID

pModelSpaceTblRcd->newIterator(pModelSpaceItr);

 

 

// Go to the block reference / objectID

if(pModelSpaceItr->seek(thePANBLKBlockId) != Acad::eOk)

{ AfxMessageBox(_T("Internal Error !"));

delete pModelSpaceItr; pModelSpaceTblRcd->close(); return false; }

 

 

// Access the block reference

pModelSpaceItr->getEntity(pEntity, AcDb::kForWrite);

pBlockRef = AcDbBlockReference::cast(pEntity);

 

 

// Prepare iterator to move through block's attributes

pAttrItr = pBlockRef->attributeIterator();

 

 

for(pAttrItr->start();

!pAttrItr->done();

pAttrItr->step())

{

acdbOpenAcDbObject(pObject, pAttrItr->objectId(), AcDb::kForWrite);

pAttribute = AcDbAttribute::cast(pObject);

_tcscpy_s(tagBuffer, SINGLE_LINE_INPUT_LENGTH_SHORT, pAttribute->tag());

 

 

pAttribute->upgradeOpen();

 

 

// LEFTBFHGT

if(_tcscmp(tagBuffer, _T("LEFTBFHGT")) == 0 ||

_tcscmp(tagBuffer, _T("LEFTHEIGHT")) == 0 )

{

TCHAR attrText[COMMENT_LENGTH_SHORT];

_tcscpy_s(attrText, COMMENT_LENGTH_SHORT, pAttribute->textString() );

 

 

AcDbAttributeDefinition *tempAttrDefinition = new AcDbAttributeDefinition();

tempAttrDefinition->setPosition(pAttribute->position() );

tempAttrDefinition->setTag(_T("LEFTFFHGHT"));

tempAttrDefinition->setPrompt(_T("Left Front Face Height."));

tempAttrDefinition->setTextStyle(idTextStyleLeroy);

tempAttrDefinition->setHeight(.32);

tempAttrDefinition->setRotation(0);

 

 

pAttribute->setAttributeFromBlock(tempAttrDefinition, pBlockRef->blockTransform() );

pAttribute->transformBy(pBlockRef->blockTransform() );

pAttribute->downgradeOpen();

 

 

pModelSpaceTblRcd->appendAcDbEntity(pEntity);

 

 

pBlockTbl->upgradeOpen();

pModelSpaceTblRcd->upgradeOpen();

 

 

tempAttrDefinition->close();

}

pAttribute->close();

}

 

// Free the attribute iterator

delete pAttrItr;

 

 

pBlockRef->close();

delete pModelSpaceItr;

pModelSpaceTblRcd->close();
