Failed to delete more than one layout

[chunyuran]

It's OK to delete just one layout. But when remove another layout after first delete, AutoCAD crushed.

Any ideas? Thank for your patience.

CString m_strPath = _T("c:\\ttLL.dwg");
AcDbDatabase* pDbb = acdbHostApplicationServices()->workingDatabase(); 

AcDbDatabase* pDb = new AcDbDatabase(false, true); 
if (pDb->readDwgFile(m_strPath, _SH_DENYRW) != Acad::eOk)
{
	AfxMessageBox(_T("error 1"));
	return;
}

acdbHostApplicationServices()->setWorkingDatabase(pDb);
AcDbLayoutManager* pLayoutMng = acdbHostApplicationServices()->layoutManager();

Acad::ErrorStatus es=pLayoutMng->deleteLayout(_T("Layout3"));
if(es!=Acad::eOk)
{
	AfxMessageBox(_T("error 2"));
}

es=pLayoutMng->deleteLayout(_T("Layout2")); 
if(es!=Acad::eOk) 
{
         AfxMessageBox(_T("error 3")); 
} 
acdbHostApplicationServices()->setWorkingDatabase(pDbb);

if (pDb->saveAs(m_strPath)!=Acad::eOk) 
{
         AfxMessageBox(_T("error 4"));
} 
delete pDb; 
return;

Hi,

You should only use "setWorkingDatabase" when absolutely needed. 

In this case, to delete the layouts, try this code which deletes two layouts named "MyLayout1" and "MyLayout2" :

<code>

Acad::ErrorStatus es = Acad::eOk;
AcDbDatabase *pDb = new AcDbDatabase (false, false);
pDb->readDwgFile (_T("C:\\Temp\\Test.dwg")) ;
AcApLayoutManager *pLayoutMngr =(AcApLayoutManager*)(acdbHostApplicationServices()->layoutManager());
pLayoutMngr->setCurrentLayout(ACRX_T("Model"), pDb);
pLayoutMngr->deleteLayout(ACRX_T("MyLayout1"), pDb);
pLayoutMngr->deleteLayout(ACRX_T("MyLayout2"), pDb);
pDb->saveAs(_T("C:/Temp/Test1.dwg"));
delete pDb;
