When to release the newContentControl, DO I NEED to release it by myself, or NetOffice release it?

In the DocumentEvents2.cs
public void ContentControlOnExit([In, MarshalAs(UnmanagedType.IDispatch)] object contentControl, [In] [Out] ref object cancel)
{
Delegate[] recipients = _eventBinding.GetEventRecipients("ContentControlOnExit");
if( (true == _eventClass.IsCurrentlyDisposing) || (recipients.Length == 0) )
{
Invoker.ReleaseParamsArray(contentControl, cancel);
return;
}

NetOffice.WordApi.ContentControl newContentControl = NetOffice.Factory.CreateObjectFromComProxy(_eventClass, contentControl) as NetOffice.WordApi.ContentControl;
object[] paramsArray = new object[2];
paramsArray[0] = newContentControl;
paramsArray.SetValue(cancel, 1);
_eventBinding.RaiseCustomEvent("ContentControlOnExit", ref paramsArray);

cancel = (bool)paramsArray[1];
}
Comments: ** Comment from web user: SebastianDotNet **

the newContentControl is a child from _eventclass(may Word.Document) now in NO com proxy management.
(Dispose the document instance(_eventclass) means also to dispose all the childs *your turn.)

The common way is to dispose newContentControl at last in the event trigger to keep the memory usage low, otherwise newContentControl lives so long as the parent is alive.

If have more ContentControlOnExit event handler, dispose the contentcontrol shoud be careful!

NetOffice cached the class type, I thank it can also cache the constructor.
_wrapperTypeCache.Add(fullClassName, classType);

                COMObject newClass = Activator.CreateInstance(classType, new object[] { caller, comProxy, comProxyType }) as COMObject;
                return newClass;

private static Type[] Params = new Type[] { typeof(string), typeof(string), typeof(string), typeof(XmlDocument) };

    internal void Register(Type type,  ElementNameAttribute att) {
        SpeedQName name = new SpeedQName(att.LocalName, att.NamespaceURI);
        var ctor = type.GetConstructor(Params);
        if (ctor != null) {
            DynamicMethod method = new DynamicMethod(string.Empty, type, Params);
            ILGenerator il = method.GetILGenerator();
            il.Emit(OpCodes.Ldarg_0);
            il.Emit(OpCodes.Ldarg_1);
            il.Emit(OpCodes.Ldarg_2);
            il.Emit(OpCodes.Ldarg_3);
            il.Emit(OpCodes.Newobj, ctor);
            il.Emit(OpCodes.Ret);
            Func<string, string, string, XbrlDocument, XbrlElement> fun = method.CreateDelegate(typeof(Func<string, string, string, XmlDocument, XmlElement>)) as Func<string, string, string, XmlDocument, XmlElement>;
            _qname2ImplType[name] = fun;

I think It's most fast method to Create New Object. Activator.CreateInstance do more work at runtime.
In the Factory _globalObjectList can be ignore If user don't want it by Setting, OR it should only save (cache) the root COMObject, the child COMObject is disposed by the parent object

I think should Add a method to the NetOffice.Factory.Remove(COMObject), remove it from the COMObject List who is created and not disposed.

Hi Guys.

Running 1.6 and am trying to create a Pivot Table in Excel. I can get it to generate fine as long as the SourceData range does not go over 65536. If I go to 65537 I get:

```
{"Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))"}
```

I assume there is a ushort variable limit to blame here? Here is the code that causes the problem (abbreviated to save space):

```
var workbook = ExcelApplication.ActiveWorkbook;
if (workbook == null)
return;

var DataWorksheet = (Worksheet)workbook.Worksheets.FirstOrDefault(ws => ((Worksheet)ws).Name == "Data");
if (DataWorksheet == null)
return;

var pivotsheet = workbook.Worksheets.Add() as Worksheet;
if (pivotsheet == null)
return;

// THE EVENTUAL PROBLEM WHEN > 65536
var usedrange = DataWorksheet.Range("A1:U65537");

//THIS LINE WILL CAUSE THE EXCEPTION WHEN usedrange IS > 65536
var pivotcache = workbook.PivotCaches().Add(XlPivotTableSourceType.xlDatabase, usedrange);

var pivottables = pivotsheet.PivotTables() as PivotTables;

if (pivottables != null)
{
var pivottable = pivottables.Add(pivotcache, pivotsheet.Range("A1"), "PivotTable1");
pivottable.InGridDropZones = false;
}
```

Thanks

Hi Sebastian,

First off huge thanks for NetOffice! Extrmely good stuff!

I want to store extra data about workbooks, and select the right data when a user selects another workbook (to load into a taskpane). I have this code, but if I have two workbooks open and switch between then a couple of times, they get added to the List again every time, it seems the Wb reference points to a different object every time (some wrapper?).

Is there a way to uniquely identify a workbook after the WorkbookActivateEvent (Preferably without having to use the name as it may change) ?

XL.WorkbookActivateEvent += XL_WorkbookActivateEvent;

and handler:

List<Workbook> _workbooks = new List<Workbook>();

void XL_WorkbookActivateEvent(Workbook Wb) {
    if (!_workbooks.Contains(Wb)) { 
        // reference seem different every time event is fired
        _workbooks.Add(Wb);
        Wb.SheetChangeEvent += Wb_SheetChangeEvent;
    }
}

NO 1.7 use an option to disable the com proxy management by the way. (NetOffice.Settings)
Anyway, in fact you can't improve the method call performance in this way.(this works in .NET but not in COM. )
May its possible to improve performance in CreateProcess, (just for the second call, but most of the time you do this only at once)

Hi,

Is it possible to expand a bit more on this answer? Is it possible to learn more about what the tools namespace wrapper does?

I am trying to understand that if NetOffice doesn't support Tools namespace functionality directly, then how do I go about learning more details and do controls-related stuff without going through this wrapper.

Any relevant documentation / examples please?

Regards.
