Hi,

Is there a way to findout that AcDbBlockTableRecord is dynamic block except of iterating it?

thanks in advance

static bool AcDbDynBlockReference::isDynamicBlock( AcDbObjectId blockTableRecordId );

 This method help you to identify if block is dynamic or no.

Alexander,

thanx for your reply.

but that not what i'm asking, i what to know if AcDbBlockTableRecord is dynamic?

let's say i have in database some old blocks version in AcDbBlockTable and i want to upgrade them to a new

version which is dynamic. with AcDbDynBlockReference::isDynamicBlock() i have to catch one

block reference and check it...but what if there isn't any insert? should i do a dummy insert to check it?

that's sounds unlogic.

No. This method is static. That is why you can use it same way:

AcDbObjectId idBTR; // id of BlockTableRecord
if (AcDbDynBlockReference::isDynamicBlock(idBTR)) {
  acutPrintf(_T("\nBlock is dynamic"));  
} else {
  acutPrintf(_T("\nBlock is not dynamic"));  
}

i'm sorry Alex, you are right, my mistake

thank you

Alexander,

wait...

In order to be able to use ->  AcDbDynBlockReference::isDynamicBlock(AcDbObjectId blockTableRecordId);

first you need to construct AcDbDynBlockReference with AcDbBlockReference object as an argument

AcDbDynBlockReference(AcDbBlockReference* pRef);

AcDbDynBlockReference(AcDbObjectId blockRefId);

so this send me back to start, Am i right?

NO! NO! NO!

Are you know how to call static method of class? OK. Full sample:

static void CheckDynBlock(void)
{
    ACHAR blockName[512];
    if (acedGetString(TRUE,_T("\nBlock name: "), blockName) == RTNORM) {
        AcDbBlockTableRecordPointer pBTR(blockName, acdbCurDwg(), AcDb::kForRead);
        if (pBTR.openStatus() == Acad::eOk) {
            if (AcDbDynBlockReference::isDynamicBlock(pBTR->objectId())) {
                acutPrintf(_T("\nBlock <%s> is dynamic."), blockName);
            } else {
                acutPrintf(_T("\nBlock <%s> is not dynamic."), blockName);
            }
        } else {
            acutPrintf(_T("\nCan not open block <%s>. Error: <%s>"),
                blockName, acadErrorStatusText(pBTR.openStatus()));
        }
    }
}

And what about Accept solution?
