Topic: how to control when switch out to other drawing (c++ object arx)

[binh_nx]

Hi.
I'm a new member, I have a issue and need your help:
I'm working on drawing1.dwg. And I want that when user switch out to other drawing (drawing2.dwg) or create a new drawing,
application will show "yes/no" option for user.

If Yes, drawing2.dwg will be activated.

If No, keep working on drawing1.dwg.

Please tell me, how can I do?

Thank.

Changing drawings is more of an Application thing rather than a Database event as you are changing Document instances.

Have a look into the AcApDocManagerReactor Methods in the ARX reference doc's, the AcApDocManagerReactor::documentToBeActivated may be what you are looking for.

Hi MickD,
I have tried as you say, but it doesn't seems to work.
Do I have some mistake ?

This is my Code:

// show "yes/no" question to user
void AsdkDataManager::documentToBeDeactivated(AcApDocument* doc)
{
   // show message      
   m_bSwitchOutToOtherDrawing = true;
   m_sFileNameBeDeactivated = _T("\0");
   CString sMsg = _T("Do you want to switch to other drawing?");
   if(AfxMessageBox(sMsg, MB_YESNO | MB_ICONQUESTION) == IDYES)
   {
      m_bSwitchOutToOtherDrawing = true; // switch to other drawing
   }
   else
   {
      m_bSwitchOutToOtherDrawing = false; // don't switch
      m_sFileNameBeDeactivated = doc->fileName();
   }
}
// reactivate previous drawing
void AsdkDataManager::documentToBeActivated(AcApDocument* doc)
{
   if (m_bSwitchOutToOtherDrawing) // switch to other drawing
   {
   }
   else //
   {
      if (!m_sFileNameBeDeactivated.IsEmpty())
      {
         AcApDocument* pDocReActive = NULL;
         getDocFromFilename(m_sFileNameBeDeactivated, pDocReActive);
         if (pDocReActive)
         {
            Acad::ErrorStatus es;
            m_bSwitchOutToOtherDrawing = true;
            m_sFileNameBeDeactivated = _T("\0");
            es = acDocManager->activateDocument(pDocReActive); // reactivate previous drawing
         }
      }
   }
}

Have you tried any other reactors to test that your reactor is getting added to the doc manager?

I'm not really set up to do any testing, if I get time tomorrow I'll take a closer look.
Someone with more C++ experience will probably pop in before then, it's been a long while since I've used it

Also, it might be worth trying to run your code in the documentActivated method, it will achieve the same result I think.

I have tried with documentActivated method. It works when switch drawing but it still doesn't work when create new drawing.

I think documentActivated is more of a windows focus event, are you looking for documentBecameCurrent?

[binh_nx]

i have tried with documentBecameCurrent. But it is complex to control the loop.
Because documentBecameCurrent method is called in activating process. So it makes the loop between activate document and Deactivate document.
Do you have any comment to control this lop?
I think  previous document should be reactivated after current document is activated. But i don't know the way to do this. OMG !!!
