Word: Documents.Add and Arrays

Hi,

sorry if this question is a faq, but i'm in trouble with invoking the
Function Word.Documents.Add. That function takes four arguments, all of them
optional and all of them of Type Variant[]. How do i set these arguments
(important for me is only the first one, taking the document template)?

_Document oDocument;
Documents docs = app.getDocuments();

Variant[] varVorlage = new Variant[1];
varVorlage[1] = new Variant();
varVorlage[1].vt = VarTypes.VT_BSTR;
varVorlage[1].bstrVal = VORBLVORL;

Variant[] varTempl = new Variant[1];
varTempl[0] = new Variant();
varTempl[0].vt = VarTypes.VT_BOOL;
varTempl[0].boolVal = false;

Variant[] varTyp = new Variant[1];
varTyp[0] = new Variant();
varTyp[0].vt = VarTypes.VT_INT;
varTyp[0].intVal = WdNewDocumentType.wdNewBlankDocument;

Variant[] varTempl2 = new Variant[1];
varTempl2[0] = new Variant();
varTempl2[0].vt = VarTypes.VT_BOOL;
varTempl2[0].boolVal = true;

oDocument = docs.Add(varVorlage, varTempl, varTyp , varTempl2);

leads to a COMException:Unable to serialize variant.

Any hints or any working example?


Thank you
Florian
