Dear Developers,

I am Facing a problem in Word.Document.SaveAs(,)
It Shows Error "No overload for method 'SaveAs' takes '11' arguments"
when I run application on OTHER MACHINE which also using Office2003.
Same Applicaiton works On My machine with 16 arguments



//Framework 2.0 With c#

//Reference Used:Interop.Microsoft.Office.Core.dll
//Interop.VBIDE.dll
//Interop.Word.dll
Word.Document aDoc = WordApp.Documents.Add(ref fileName, ref newTemplate, ref docType, ref isVisible);
object destFile = @"C:\MyDir\" + txt1.Text + ".doc";
//some code..
aDoc.SaveAs(ref destFile, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1);
