In clode i have clearly closed anf kille dthe objects

like,

myExcel.Close

set myExcel as nothing
set myWorkSheet as nothing
set myWorkBook as nothing


But in task manager i can see Excel.exe

Please reply

You can always use the FindWindow-function and the PostMessage-function to find the wanted application, and then send it a message that it has to close itself. One disadvantage: you'll need the exact caption of this application.

Try this

VB Code:

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_CLOSE = &H10
Private Sub Form_Load()
Dim winHwnd As Long
Dim RetVal As Long
winHwnd = FindWindow(vbNullString, "Calculator")
If winHwnd <> 0 Then
PostMessage winHwnd, WM_CLOSE, 0&, 0&
Else
MsgBox "The Calculator is not open."
End If
End Sub

Thanx to AllAPI

Its bad programming practice to try to terminate a running process or sending the close message to it. Its better to find the offending code and correct it. You should never need to use a workaround to close Excel when you are automating it if its done correctly. :)

Its all about disposing of the Excel objects in the proper order in order to prevent the orphaning of the object heirarchy. Also, never use the implicit Excel objects without using an object variable for them. Ex. Range object.

Any sheet or range object variables set to Nothing.
Then .Close any Workbooks.
Then set your workbook(s) = Nothing
Then .Quit your Excel.Application object variable.
Then set it equal to Nothing

Thank you very much
actually i had one more reference which is not closed...

I made it nothing....

Thanks alot for reply

It was the order and not closing of the workbook just from what I seen in your first post.

Glad to have helped. :)
