Can events be hooked to MS Word?

[kobus]

Hi

I am opening a MS Word document using C# code.


Word.ApplicationClass WordApp = new Word.ApplicationClass();

// Use the open file dialog to choose a word document
if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
{
object fileName = openFileDialog1.FileName;
object readOnly = false;
object isVisible = true;

//Here is the way to handle parameters you don't care about in .NET
object missing = System.Reflection.Missing.Value;

//Make word visible, so you can see what's happening
WordApp.Visible = true;

//Open the document that was chosen by the dialog
Word.Document aDoc = WordApp.Documents.Open(ref fileName, ref missing,ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible);


//Activate the document so it shows up in front
aDoc.Activate();
}


This works fine and it opens the document in MS Word separate from the C# application. Is there a way of hooking an event to the document object (aDoc) so that when the word document is closed the C# application can react to the event?

Thanks

Hi,
Yep the events are available. Here is an example


WordApp.ApplicationEvents3_Event_DocumentBeforeClose+=new Word.ApplicationEvents3_DocumentBeforeCloseEventHandler(wd_ApplicationEvents3_Event_DocumentBeforeClose);

..............

void wd_ApplicationEvents3_Event_DocumentBeforeClose(Word.Document Doc, ref bool Cancel)
{
................
}

Hi stepi

Thanks for the post. This works well when the whole MS Word application is closed. Is there anything similar for when only a particular document in the MS Word application is closed? I cannot seem to find anything like that. If not, would a person be able to write an event for that?

Thanks.

Hi again,
There is no event on the Document class that will tell you when it is closing. You can use though this event at application level. You will need a work around to identify your document. You are opening the document so you have aDoc as reference to you word document.


Word.Document aDoc;
...............

void wd_ApplicationEvents3_Event_DocumentBeforeClose(Word.Document Doc, ref bool Cancel)
{
if(Doc == aDoc)
{
//your special routine
}
}


You can use the document name to identify your document, but i don't find this solution reliable.
