在我们建立标注样式或文字样式时都习惯把他们设一个名字，如setName(_T(“仿宋”))

但是取了名字之后有一个问题就是，下次再调用这个程序是，如果程序识别到已经有这个名字的存在，它就不会再对样式表进行设置了，所以我们很多时候调用了一次，下次调用发现根本就没起作用就是这个道理。（当然这也是我自己的判断）。

//隐形函数，需要自己定义

bool acedLinetypeDialog( AcDbObjectId old_linetypeId, // ObjectId for current linetype: acdbCurDwg()->celtype();

bool IncludeByBlockByLayer, // Posibility of selecting “bylayer” or “byblock”   TCHAR *&new_linetypeName, // Name of selected linetype

AcDbObjectId &new_linetypeId // ObjectId for selected linetype

);

//调用

AcDbObjectId new_linetypeId;

TCHAR * new_linetypename = NULL;

if(!acedLinetypeDialog(acdbCurDwg()->celtype(),false,new_linetypename,new_linetypeId))

{

return;

Question

How can I create xrefs using ObjectARX?

Answer

The following function have been introduced with ObjectARX 2000:

acedXrefAttach() acedXrefOverlay() acedXrefUnload() acedXrefDetach() acedXrefReload() acedXrefBind() acedXrefXBind() acedXrefCreateBlockname()

The ObjectARX Reference Manual does not document these function that has been logged as documentation defect. Here’s more information on them:

Common rules: 1. All Xref APIs operate on the current document only. 2. The APIs provide document locking internally, if the document cannot be locked they return Acad::ErrorStatus eLockViolation. 3. No input validation or range checking is done other than checking for NULL pointers or strings. Input validation is the caller’s responsibility. 4. Xref log file processing is available if option is enabled. 5. Normal AutoCAD behavior with regards to output indicators, such as, progress meters, and msgs, may be turned off when scripts enabled && cmdecho == 0, or menu macros enabled && menuecho == 0, or menu encryption set.

—– Acad::ErrorStatus acedXrefAttach(const char* XrefPathname, const char* XrefBlockname, AcDbObjectId* pXrefBTRid = NULL, AcDbObjectId*    pXrefRefid     = NULL, const AcGePoint3d* pXrefInsertPt = NULL, const AcGeScale3d*    pXrefScale = NULL, const double* pXrefRotateAngle = NULL, const Adesk::Boolean bQuiet = Adesk::kTrue);

——- Acad::ErrorStatus acedXrefOverlay(const char* XrefPathname, const char* XrefBlockname, AcDbObjectId* pXrefBTRid = NULL, AcDbObjectId*    pXrefRefid = NULL, const AcGePoint3d* pXrefInsertPt = NULL, const AcGeScale3d* pXrefScale = NULL, const double* pXrefRotateAngle = NULL, const Adesk::Boolean bQuiet = Adesk::kTrue);

—– Acad::ErrorStatus acedXrefUnload(const char* XrefBlockname, const Adesk::Boolean bQuiet = Adesk::kTrue);

Unloads the Xref block by its given block name. This assumes a valid Xref block exists in the current document.

Binds symbols from xrefs to the current drawing.

Returns: Returns Acad::eOk if operation is successful.

Parameters: const AcDbObjectIdArray [in] object ids of symbol table records to be bound const Adesk::Boolean bQuiet [in, optional] Flag to suppress output msgs

—– Acad::ErrorStatus acedXrefCreateBlockname(const char* XrefPathname, char*& XrefBlockname);

Accepts a Xref file pathname and returns an internally allocated block name symbol string buffer which follows the AutoCAD policy rules for its creation. Typically, is composed of the filename of the Xref file. A return error will occur if the block name cannot be created. The block name string’s buffer must be released via the acutDelString().

Returns: Returns Acad::eOk if operation is successful.

Parameters: const char* XrefPathname [in] pointer to a Xref file pathname char*& XrefBlockname [out] Returns a pointer to a copy of the block name symbol string
