C++ Close command does not purge *lck file

[Anonymous]

Hi, 

I have a trouble with my current Inventor Application coded in C++.

Here what I do :

- Copy an ipt file into a temp folder

- Load the ipt file into Inventor.

- Save it as sat.

- Close the document

- Delete the temp folder

The problem I have is the following, I can't delete the temp folder because there is a lockfile.lck file, even if I wait a few seconds the file is still there and prevent my delete action.

What I notice is : 

- if I start Inventor (GUI opens), the problem happens.

- if I do not start Inventor, the problem does not happen.

Here is the code I use :

mModelDoc = application->Documents->Open(
static_cast<LPCTSTR>( filePath ),
VARIANT_FALSE
);

CString newFilePath = folderPath; ::PathAppend( newFilePath.GetBuffer( MAX_PATH ), fileName + _T( ".sat" ) ); newFilePath.ReleaseBuffer();
mModelDoc->SaveAs( static_cast<LPCTSTR>( newFilePath ), VARIANT_TRUE);
mModelDoc->Close( VARIANT_TRUE ); mModelDoc = NULL;

Can someone help me to understand the problem?

Thanks,

Hi! Could you tell me what release of Inventor you are using? I cannot seem to reproduce it on 2018.

Many thanks!

Thanks for your quick reply.

I have used 2018 and 2016 version and I got the same results. I even tried a very old version inventor 11 and I had same results.

I guess I have missed something which must be linked with the way I load the model. With the Inventor GUI case, I have noticed that when I called the load function, I see updates on the application task-bar :

1. Module loaded
2. Loading file xxx.ipt
3. Loading...

It keeps on displaying 'Loading...' and I don't see the model loaded graphically. When code reaches 'saveas' command, it does the job but the close function does not seem to have any effects.

Could you send me your test code so that I could identify what I did wrong?

Hi! I did not try the workflow programmatically. I manually delete the folder and the lck file after close doc. It seems to work fine. Could you try it manually and see if the same behavior happens?

Many thanks!

Is the inventor application correctly released?

I have tested it manually and all seems ok : I have deleted the *.lck after unloading the file.

I think so, I am able to use Inventor without any issues.

With released I mean unloaded from task manager.

I have solved my problem.

It seems Inventor needs to have full control on the folder where the model file is. I have solved my problem by copying the model into a temp folder and perform all action there.

What I don't understand is that the folder where the model initially seats, everyone - full control rights.

Thanks everyone for help.
