Automating Word application in C#

[Noam Ben Haim]

Hi all, I am trying to write some small app that automates Word Application (mainly MailMerge, and sending word documents to the printer), and I have come to a problem. Using the Missing.Value as a missing parameter (which is a good thing to do in every other method of the word app) will not work as most of the methods need a ref object as a parameter. does anyone have a clue? thanks Noam I attach a small piece of code for example. this code does not compile, for the above reason. Word._Application word = new Word.ApplicationClass(); Word.Document doc = (Word.Document)word.Documents.Open(ref m_confirmationFile, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); Word.MailMerge mailMerge = (Word.MailMerge)doc.MailMerge; mailMerge.CreateDataSource("Data.doc", Missing.Value, Missing.Value, "CandidateID, FirstName, LastName, Address", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); Word.Document dataDoc = (Word.Document)word.Documents.Open("Data.doc", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); Word.Table tbl = (Word.Table)((Word.Tables)dataDoc.Tables).Item(1); tbl.Cell(2, 1).Range.InsertAfter(candidateId); tbl.Cell(2, 2).Range.InsertAfter(firstName); tbl.Cell(2, 3).Range.InsertAfter(lastName); tbl.Cell(2, 4).Range.InsertAfter(address); dataDoc.Save(); dataDoc.Close(Missing.Value, Missing.Value, Missing.Value); mailMerge.Destination = Word.WdMailMergeDestination.wdSendToPrinter; mailMerge.Execute(Missing.Value); doc.Close(Missing.Value, Missing.Value, Missing.Value); Noam Ben Haim Web Developer Intel noam.ben.chaim@intel.com

Try null? Might not work but it's a clue. Paul

string s = @"c:\mydoc.doc";
object so = (object) s;
object o = null;
Word.Document doc = word.Documents.Open(ref so,ref o,ref o,ref o,ref o,ref o,ref o,ref o,ref o,ref o);

(the ref stuff is because the tlbimporter is stupid, and prefers to assume nothing, even when the type-library brings everything top-to-bottom and left-to-right). Have fun!! :cool:
