Document "xxx.dwg" has a command in progress.

Anonymous — Mon, 22 Jan 2007 23:04:26 GMT

I have a .NET app that shows a modeless dialog which is a customized print application.
It works fine except when I try to use the "qsave" command on the drawing after plotting or previewing it.
I get a message at the command line:
Document "xxx.dwg" has a command in progress.

Other commands such as Line, Copy, Move etc. work fine. Even the "Save" command works.

I've searched and read every post I could find on this subject including some in Russian (which may have lost something in the translation to English).

Is there some way to tell the Document that it doesn't have a command in progress?

Does your app lock the document during its execution? If so, how does it unlock it?

Yes I lock the document (variable named ThisDrawing) with ThisDrawing.LockDocument()

Then at the end of the function I use this:
ThisDrawing.LockDocument(DocumentLockMode.NotLocked, string.Empty, string.Empty, false);

Document ThisDrawing = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
DocumentLock dLock = ThisDrawing.LockDocument();
// modify the database here
dLock.Dispose();

Which of the two do you use? The first one is wrong. The second should work and allow you to execute commands after its completion.

What -two- do you mean?
The first part is to create the lock and the last is to dispose of the lock.

You have answered twice to my question.
The first answer:

"Yes I lock the document (variable named ThisDrawing) with ThisDrawing.LockDocument()

Then at the end of the function I use this:
ThisDrawing.LockDocument(DocumentLockMode.NotLocked, string.Empty, string.Empty, false);"

describes a wrong method.

The second answer:

" Re: Document "xxx.dwg" has a command in progress.
Document ThisDrawing = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocum ent;
DocumentLock dLock = ThisDrawing.LockDocument();
// modify the database here
dLock.Dispose();"

is correct.

In general, you should lock the document any way you want, but to unlock it, you just dispose the object you got when you locked the doc. I don't know what "NotLocked" is for, but it sure does not unlock the document.
This locks the doc (as you already know):
DocumentLock dLock = ThisDrawing.LockDocument(DocumentLockMode....., ...., ...., ....);
then you do your work...
...
and lastly you unlock the doc to allow for other commands to manipulate it:
dLock.Dispose();

Ah, I understand what you were asking now.
Yes, I was mistaken in thinking that .LockDocument(anything here) could UNLock a document.
