Topic: Checking and loading linetypes in .Net ObjectARX

[cannorth]

Hello,

   I'd like to know how to write code that would check if a linetype exists and if it doesn't, then it will load the linetype from a .lin file.

Thanks,

no sample i have available in .net but this is what i have used in arx - hth:

Code - C++: [Select]

1. Acad::ErrorStatus loadLinetype(const ACHAR *entryName, const ACHAR *filename = _T("acad.lin"))
2. {
3.         Acad::ErrorStatus es;
4.         AcDbLinetypeTable* pTable;
5.         AcDbObjectId recordId;
6.         es = acdbCurDwg()->getLinetypeTable(pTable, AcDb::kForRead);
7.         if ((es = pTable->getAt(entryName, recordId)) != Acad::eOk);
8.         {
9.                 es = pTable->close();
10.                 es = acdbCurDwg()->loadLineTypeFile(entryName, filename);
11.         }
12.         return es;
13. }
14.  
15. // and from your entry point... load your linetypes.
16.         virtual AcRx::AppRetCode On_kLoadDwgMsg (void *pkt) {
17.                 AcRx::AppRetCode retCode =AcRxArxApp::On_kLoadDwgMsg(pkt) ;
18.                
19.                 AcApDocument* pDoc;
20.                 pDoc = acDocManager->curDocument();
21.  
22.                 pDoc->pushDbmod();
23.  
24.                 const ACHAR* items[] = { _T("BORDER"), _T("CENTER"), _T("DASHED"), _T("DASHDOT"), _T("HIDDEN"), _T("PHANTOM") };
25.                 std::vector<const ACHAR*, std::allocator<const ACHAR*>> v (items, items + sizeof items / sizeof *items);
26.                 for (int i = 0; i < v.size(); i++) loadLinetype(v.at(i)); v.clear();
27.                
28.                 pDoc->popDbmod();
29.  
30.                 return (retCode) ;
31.         }
