How do I create a folder as a child of a project using LAPI ?

[Tailes]

Hi All.
What I need is to create a folder inside LiveLink project using LAPI in C++. I use "LL_CreateObjectEx" function for creating project and "LL_CreateFolder" for folder. The expected result is the folder as child of project, but it is displayed as a subproject object.

Here is the source:

LL_Initialize( LL_HEADER_VERSION );
LL_SessionAllocEx( &session, m_repositoryName, m_nPort, _T("livelink"), m_userName, m_password, NULL );
LL_ValueAlloc( &objectInfo );
LL_ValueAlloc( &createInfo );
LL_ValueSetAssocInArgs( createInfo );
LL_AccessEnterpriseWS( session, objectInfo );
LL_AssocGetInteger( objectInfo, "ID", &parentID );
LL_AssocGetInteger( objectInfo, "VolumeID", &parentVol );
LL_CreateObjectEx( session, parentVol, parentID, LL_OBJECTTYPE, LL_PROJECTSUBTYPE, "Project1", createInfo, objectInfo ); //// project is created correctly
LL_AssocGetInteger( objectInfo, "ID", &parentID );
LL_CreateFolder( session, parentVol, parentID, "Folder1", objectInfo ); //This creates a subproject folder

If I create the folder manually it appears as simple subfolder. The question is what should I do to create a folder in a project that is not a subproject?

Thanks in advance,
Alexander.

I do not know perhaps yours is a customized lapi header/class but OT standard lapi libraries does not include a LL_CreateFolder signature.

However I would advise you to read this section on the lapi documentation
Appendix B: Valid Object Parentage which is in sort a disclaimer of how things you program.
In any case the CreateObjectEx call can actually be used to
create a folder in a project object subtype.The only pre-conditions are the folder's parentid is the project object's ID and its volume.There used to be a bug in the volume concept so in most cases volume of zero does not hurt so long as you get the parentid right.
So something like

LL_CreateObjectEx( session, parentVol of my project or zero, parentID of my Project Object, LL_OBJECTTYPE, LL_FOLDERSUBTYPE, "Folder1", createInfo2, objectInfo ); ////

Try to see if this fixes anything

Thank you for your reply, but unfortunately it did not help. The folder is created as a child of a project, right, but it is displayed in a list of "Sub-Projects", while I need it to appear in a list of generic sub-objects.

Actually I meant dataid of the parent object

My Bad,

LL_CreateObjectEx( session, parentVol of my project or zero, DatatID of my Project Object, LL_OBJECTTYPE, LL_FOLDERSUBTYPE, "Folder1", createInfo2, objectInfo ); ////

Since you say it is not working to spec let me try a quick sample.
You want to create a project and add a folder in it correct ? and the folder should be a regular ll folder ...

Here's what I could find you need to make the container object which is the project a negative,and make the volume 0.
Apologize for java code and a lot of debugging but towards the end you can see how I am doing this
This creates a project object and myuy next call I created a folder object.I did this on a 9.5 sp1 oracle machine using 9.5 lapi class libraries

Thenk you for your help. After several tests I have finally found out the way it has to be in my case.

LL_Initialize( LL_HEADER_VERSION );

LL_SessionAllocEx( &session, m_repositoryName, m_nPort, _T("livelink"), m_userName, m_password, NULL );

LL_ValueAlloc( &objectInfo );
LL_ValueAlloc( &createInfo );
LL_ValueSetAssocInArgs( createInfo );

LL_AccessEnterpriseWS( session, objectInfo );
LL_AssocGetInteger( objectInfo, "ID", &parentID );
LL_AssocGetInteger( objectInfo, "VolumeID", &parentVol );

LL_CreateObjectEx( session, parentVol, parentID, LL_OBJECTTYPE, LL_PROJECTSUBTYPE, "Project1", createInfo, objectInfo );

LL_AssocGetInteger( objectInfo, "ID", &projectID );
LL_AssocGetInteger( objectInfo, "VolumeID", &projectVol );

LL_CreateObjectEx( session, projectID, -projectID, LL_OBJECTTYPE, LL_FOLDERSUBTYPE, "Folder1", createInfo, objectInfo ); // this creates a generic subfolder

//LL_CreateObjectEx( session, projectVol, projectID, LL_OBJECTTYPE, LL_FOLDERSUBTYPE, "Folder1", createInfo, objectInfo ); // this created the Sub-Project item.

Now it is working the way I need. Thanks again.
