AcApDocManager::sendStringToExecute and reactor documentCreated

Anonymous — Sun, 27 Aug 2006 14:18:40 GMT

Hi Guys,
It seems the function
AcApDocManager::sendStringToExecute won't work properly within the
AcApDocManagerReactor::documentCreated
It always returns eNoDocument in that case. I tried documentActivated and
documentBecameCurrent, same disappointment.
I need to send an AutoLisp line as soon as the document gets created and I
thought it is the best place to do so.
Is there a way to achieve this (other than old "acad.lsp")?
Your help is very much appreciated.
Thanks heaps.
Charlie.

Try instead ads_queueexpr() or acedPostCommand() or use ::SetTimer() function on AcApDocManagerReactor::documentCreated() and AcApDocManager::sendStringToExecute() in timer callback function Message was edited by: Alexander Rivilis

Hi Alexander,
SetTimer fails sometimes when loading big dwgs.
The other functions are not published, what is the lib?
Thanks heaps, you help many when you help one!

🙂 What about check result of AcApDocManager::sendStringToExecute() and if it is fails - restart timer? It is easy!

Alexander,
I tried both methods and they both crashed when dwg is of a good size (like
>1.5M)...
Any ideas why?
Thanks heaps,
Charlie.

Explain more your's problem. Maybe your's code crash AutoCAD?
1) What error messge?
2) What version of AutoCAD?
3) What doing command (code) started with sendStringToExecute?
4) Are you locking document in your's code?
5) Are you remembering to destroy timer beforer sendStringToExecute? Message was edited by: Alexander Rivilis

No error message, AutoCAD just hangs there, eating memory.

2) What version of AutoCAD?
AutoCAD2007

3) What doing command (code) started with sendStringToExecute?
it is in documentCreated of a reactor.
A> USING ads_queueexpr version:
void MyDocReactor::documentCreated( AcApDocument *pDoc )

{

if (pDoc != NULL)

{

CString cmd = L"(load \"my_lisp_file.fas\")))\n";

ads_queueexpr(cmd.GetBuffer());

}

}

B> USING sendStringToExecute version using a timer:
void MyDocReactor::documentCreated( AcApDocument *pDoc )

{

if (pDoc != NULL)

{

CDocument *cDoc = pDoc->cDoc();

POSITION pos = cDoc->GetFirstViewPosition();

CWnd *view = cDoc->GetNextView(pos);

view->SetTimer(ULTRA_TIMER,10000,TimerProc); // react after 10 seconds -> it
still crashes on good size drawings

}

}

// the TimerProc function
void CALLBACK EXPORT TimerProc(

HWND hWnd, // handle of CWnd that called SetTimer

UINT nMsg, // WM_TIMER

UINT_PTR nIDEvent, // timer identification

DWORD dwTime // system time

)

{

if (nIDEvent == ULTRA_TIMER)

{

CString cmd = L"(load\"my_lisp_file.fas\")))\n";

if (SendString(cmd) != Acad::eNoDocument)

KillTimer(hWnd,nIDEvent); // once it succeeds kill timer

}

}

// In the SendString function I am doing
pDocManager->activateDocument(pDoc, true); // a must

pDocManager->lockDocument(pDoc); // maybe a must but don't play with fate

pDocManager->sendStringToExecute(pDoc, sCommandLine, true, true, false);

pDocManager->unlockDocument(pDoc); // maybe a must but don't play with fate

4) Are you locking document in your's code?
Yes.

5) Are you remembering to destroy timer beforer sendStringToExecute?
I do it just after, but note that using ads_queueexpr is causing the same
problems.

Thanks heaps.

Charlie.

Alexander,
I think there is a function in my_lisp_file.fas that is causing the huge
delay in big drawings.
Thanks so much for your help, it is very much appreciated and it was very
valuable.
I would use ads_queueexpr, it is simpler than SetTimer.

Charlie.

Hi, Charlie!

It is only if my_lisp_file.fas is autoexecution (e.g. after loading it is start)
You can easy test it. Open this "big" dwg-file and do (load "my_lisp_file.fas").
If AutoCAD hang - search for bug in my_lisp_file.fas
If AutoCAD do not hang - debug your's arx-file

c> I would use ads_queueexpr, it is simpler than SetTimer.

Yes. It is simpler but:
1) echo in command line
2) may be execute only in active document.

Best Regards,
Alexander Rivilis.

I had used sendStringToExcecute() once, but not part of a reactor, have you
tried with (vl-load-com) (vl-load-all "yourFas.fas") or what if you loaded
in your entryPoint() in the AcRx::kInitAppMsg message using the (vl-load-all
filename) function?

I didn't use vl, it needs the document to be well created for it to load any
lisp stuff, otherwise it would fail.

I did a quick test using just (load "filename.fas") and works in the
documentActivated() and documentBecameCurrent() events, cannot make it load
in the documentCreated() event.
