Answer 1

Hi CoolMayur,

Welcome to the MSDN forum.

Would you like to provide the code about “checking document.saved() in IF”. The document.saved method can’t be the judgment of if statement. If the method failed (your situation), the VS will stop the application and give you an exception instead of return a False value to the IF.

In my opinion, you can avoid doing this. You can force the word to save the file when you close the word in your application. Here is a sample:

ObjDoc.Close(SaveChanges:=True)

Hope this helps. If I misunderstood, please feel free to let me know.

What to do in case word process get closed from out side of application, but my application is runs word in Not-Responding mode so if i click on close
button it calls form_closing event and in that event when i check that whether document is saved or not before going to save document system throws exception.

Hi CoolMayur,

Whatever you dealing with word application after you close it, it will cause the issue. So this exception is caused by design. You need to do something to avoid this.

Here are two suggestions.

1. Force the word application can’t be closed before the application close.

2. Add a Boolean value to record whether the word application is closed. If yes, avoid all code to deal with the application. Here is a sample made for you, the close boolean will be true when you close the word application.

Imports Microsoft.Office.Interop
Imports Microsoft.Office.Interop.Word

Public Class Form2
    Dim close As Boolean = False
    Event DocumentBeforeClose As ApplicationEvents4_DocumentBeforeCloseEventHandler

    Private Sub Form2_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Dim app As Word.Application = New Word.Application()
        app.Visible = True
        Dim doc As Word.Document = app.Documents.Add
        AddHandler app.DocumentBeforeClose, AddressOf checkopen
    End Sub
    Public Sub checkopen(doc As Word.Document, ByRef cancle As Boolean)
        close = True
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        MessageBox.Show(close.ToString)
    End Sub
End Class

Hope this will make it more clearly.
