Hi,
I am a new ADX product user.
When I try to open a new word document in my addin by using AddinExpress.MSO.ADXAddinModule.CurrentInstance.HostApplication that I cast to Word._Application before, it throws a HRESULT Exception : 0x80020005 (DISP_E_TYPEMISMATCH).
The HostApplication real type is Word.ApplicationClass.
I open the document by this way: 


AddinModule addinModule = (AddinModule)AddinExpress.MSO.ADXAddinModule.CurrentInstance;
object hostApp = addinModule.HostApplication;
Word._Application wordApp = hostApp as Word._Application;
Word.Document doc = wordApp.Documents.Add(ref filename, ref missing, ref missing, ref missing);
doc.Activate();


Is there the best way to do it?
Help, please.

Hi Bakary, 


//Word._Application wordApp = hostApp as Word._Application; 
Word.Document doc = addinModule.WordApp.Documents.Add(ref filename, ref missing, ref missing, ref missing);


This is the only thing I would change in your code; it is a minor one, however.

Hi Bakary,

Try using three separate variables to pass Type.Missing to the Add method.

Hi Andrei,

Thank for your replay. 


Word.Document doc = addinModule.WordApp.Documents.Add(ref filename, ref missing, ref missing, ref missing);


Works well.
