InvokeHelper

I am trying to insert a file into an existing word document (the file to be inserted is a word document as well). I created a Range object (used msword8.olb) and after strugging with the param conversion I came up with the following:

//dispatch interface
LPDISPATCH wordDisp=pActiveItem->GetIdispatch();

_Document wordDoc(wordDisp); //valid
Range rangeDoc(wordDisp); //valid??

if (wordDisp!=NULL)
{
COleVariant covOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);
COleVariant covFalse((short)FALSE);

CString csFile="docinsert.doc";

rangeDoc.InsertFile(csFile,&covOptional,&covOptional,&covOptional,&covOptional);
}

the InsertFile fails with invalid number of parameters. The dispatch interface is valid as I am able to use the wordDoc object to save the file being edited in my application. Any help would be appreciated.

Hi!!!

I just had the same problem and searched quite a time to solve it.
The trick is, as always, pretty simple as long as you know it:

The RANGE param isnt a real Range Object. Just try this:

//Prepare an "empty" range (where range at this time is meant as "string"

VARIANT var;
VariantInit(&var);
var.vt = VT_BSTR;
var.bstrVal = BSTR("");

//the call:
Selection.InsertFile("FILE.doc", &var,
COleVariant((long) 0, VT_BOOL),
COleVariant((long) 0, VT_BOOL),
COleVariant((long) 0, VT_BOOL)
);

This works just fine.
