Creating/Saving MSWord documents from C# application

[Pohihihi]

Hello NG,

Never used interOps for programming so for many this might be a very small
problem. Basically I have 2 questions --

1- Code given below creates WinWord.exe instance and even after application
terminate MS-Word is left open. If I use task manager to see how many
instances are created then one instance is created and terminates but other
stays. In other words, 2 instances are created and one is left active. I
know code is buggy but I don't know why is this happening. In my
understanding all the local objects (thus instances) should terminate after
leaving function.

2- Second problem is inlined in the code.

Thank you,
Po

//Ref: Microsoft Office 11.0 Object Library
private void LoadWord(object sender, System.EventArg s e)
{
Microsoft.Offic e.Interop.Word. ApplicationClas s oApp = new
Microsoft.Offic e.Interop.Word. ApplicationClas s();
object oMissing = System.Reflecti on.Missing.Valu e;
Microsoft.Offic e.Interop.Word. _Document oDoc = oApp.Documents. Add(ref
oMissing, ref oMissing, ref oMissing, ref oMissing);
// This is where I want to load value from DB column rather open a file
oDoc.Content.Te xt = "what a file";
string sString = @"C:\\file.doc" ;
object oString = sString;

// Here I want to save it into DB after changing the format to RTF
oDoc.SaveAs(ref oString,ref oMissing,ref oMissing,ref oMissing,ref
oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref
oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref
oMissing,ref oMissing);
