    Hello,

    I try to read the user data from base objects with the BrowseGetNext(..) function.
    I get back the DescID and a basecontainer with the data.
    But now i don't know how i can access to this data. Which IDs should i using?
    I get only the name of the "User Data" with following function.

    ...
    while ( pUserData->BrowseGetNext(handle, &id, &data) )
    {
      uid = id[1].id;
      uType = id[1].dtype;
      GeData att_name;

    att_name = data->GetData(1);
    }

    But i need also the value of it and some furter informations like min and max values or so.
    Has anyone an idea?

    ok, now i get the additional attibutes like min and max value with the BrowseContainer class.
    But i don't get the value of the user data. Only the information, that a DA_CUSTOMDATATYPE is delivered.

    BrowseContainer brw(data);
                  LONG lid = 0;
                  GeData *att = NULL;

    while (brw.GetNext(&lid, &att)) {...

    How can i read the data value ???

    hi,

    every type. I add the User data in the attribute manager and choosen one type from the list. (Boolean, Integer, Real...). And with a plugin i like to export this data into an external file.

    regards

    Ah, ok. That's actually quite simple.

    Here is an example how to determine the data type and value of the user data entries:

      
Bool MenuTest::Execute(BaseDocument *doc)  
{  
  BaseObject *op = doc->GetActiveObject();  
  if (!op) return FALSE;  
  
  DynamicDescription *dd = op->GetDynamicDescription();  
  if (!dd) return FALSE;  
  
  void *dhandle = dd->BrowseInit();  
  
  DescID id;  
  const BaseContainer *bc = NULL;  
  
  while (dd->BrowseGetNext(dhandle, &id, &bc))  
  {  
      GeData data;  
  
      if (op->GetParameter(id, data, 0))  
      {  
          //data contains the user data data; the data type of the user data  
          switch (data.GetType())  
          {  
              case DA_REAL:  
                  GePrint("Real: "+RealToString(data.GetReal()));  
                  break;  
              case DA_LONG:  
                  GePrint("LONG: "+LongToString(data.GetLong()));  
                  break;  
          }  
      }  
  }  
  
  dd->BrowseFree(dhandle);  
  
  return TRUE;  
}

    cheers,
    Matthias
