Why it crash?

[Anonymous]

Dear All:

The problem is:  When I  test those function singly, they all work well, but when I  combine them together code crash at "es = pOutputDb->saveAs(FileName);", please help me Why?

Thanks!

void MyTest::SerachBlockReference2(ACHAR* BlockName)
{
	CString pbkRefName;
	ACHAR* name;
	double d = 1;
	AcDbBlockTable* pbkTable;
	AcDbBlockTableRecord* pbkTableRcd, * mBK;

	pt3[X] = 10.0; pt3[Y] = 5.0; pt3[Z] = 0.0;
	pt4[X] = 5.0; pt4[Y] = pt4[Z] = 0.0;
	

	pCurDb = acdbHostApplicationServices()->workingDatabase();
	pCurDb->getBlockTable(pbkTable, AcDb::kForRead);
	
	if (pbkTable->getAt(ACDB_MODEL_SPACE, pbkTableRcd, AcDb::kForRead) == Acad::eOk)
	{
		pbkTable->close();

Your code contains terrible mixture of ANSI and UNICODE strings. Beginning with AutoCAD 2007, all strings used in ObjectARX must be UNICODE.
