.NET

[#1]

Hello everybody. Hope somebody could help me

In objectArx  Editor  object has  ModelessOperationWillStart . But how could I use this in my vb net ?

ObjectBrowser doesn't show it ?!!!

Janet.

I believe modelessOperationWillStart() is an ObjectRAX's AcEditorReactor class' methos, which is only available since Acad2013. It is not exposed to ObjectARX .NET API (as we all know that not everything in ObjectARX is exposed in its .NET API). thus you do not find it in the Object Browser.

Norman! This method (modelessOperationWillStart) available starting with version AutoCAD 2000 (!!!) but not yet exposed in .NET

Without ObjectARX there is no way to have modelessOperation notification.

Well, I am not very familiar with ObjectARX. But that method and/or the class (the method's owner) have been renamed in Acad2013. In this snse, one can say it is only available in Acad2013. Just like, there is a class called Person with method Run, in early version. Then in new version you rename the class Person to Human (for good or bad reasons). So, you cannot say Human.Run(0 exists since beginning in regard to programming API.

it is really a pain.

 I like to check if user change block  attributes in Properties Window (palette) . and I don't want to have an objectmodify event all the time running . that is a shame we can't do this using API.

Sorry, Norman, but you're wrong! The name of class (and base class) and name of method and parameters are the same in ObjectARX 2000 and 2013. The only difference is that this function in AutoCAD 2000 exported from acad.exe, and in 2013 from accore.dll. I skip "unicode revolution" in AutoCAD 2007.

//
// ObjectARX SDK 2000
// file aced.h
//
class AcEditorReactor: public AcRxEventReactor 
{ 
public:
//// skiped
    virtual void modelessOperationWillStart(const char* contextStr);
    virtual void modelessOperationEnded(const char* contextStr);
//// skiped
};

//
// ObjectARX SDK 2013
// file aced.h
//

class AcEditorReactor: public AcRxEventReactor 
{ 
public:
//// skiped
    virtual void modelessOperationWillStart(const ACHAR* contextStr);
    virtual void modelessOperationEnded(const ACHAR* contextStr);
//// skiped
};

 You admit your mistake?

Janet!

What about user change attribute(s) not from properties palette but (for example) with help of command _ATTEDIT  ?

[#8]

Hi again Alex and Norman.

I took care at that part (attedit) .  I  am watching  commandstart event, If it is attedit then I start  objectmodify event and if the object being modified is target block, I do necessary things I need to do . But for properties palette there is no command to catch. So basically I have to have objectmodify , on,  to watch the database all the times. there is big impact on database in my application.

Janet. Are you ready to create arx-file (ie study C++ and ObjectARX) , which help you to check object was modified from OPM or no?

If your's answer is NO, than single solution is objectmodify event, which must be simplest in order to speed up AutoCAD.

If your's answer is YES, I can help you in ObjectARX discussion group.

I've attach arx-files which exported function:

int IsOPMChangeProps();

This function can be P/Invoke from .NET (C#, VB.NET, etc.) Solution is for AutoCAD 2010...2012

[DllImport("OPMTest2010x32.arx",CallingConvention = CallingConvention.Cdecl, EntryPoint = "IsOPMChangeProps")]

private static int IsOPMChangeProps2010x32();

[DllImport("OPMTest2010x64.arx",CallingConvention = CallingConvention.Cdecl, EntryPoint = "IsOPMChangeProps")]

private static int IsOPMChangeProps2010x64();

arx-file must be loaded with help of call:

// For x86 (x32)

SystemObjects.DynamicLinker.LoadModule("OPMTest2010x32.arx", false, false);

// For x64

SystemObjects.DynamicLinker.LoadModule("OPMTest2010x64.arx", false, false);

But objectModified event must being active because this function can check status but not event (reactor).
