Whenever our script fails in middle of our execution. we need to kill excel process from the task manager. So to get rid of this issue, we can use following code. The following code does all Excel operation with kill process errors.
Just copy this code and save into a vbs/qfl/dll File and add it your library Files.
Class ExcelDocument
Dim objExcel, objWorkbook, sheetcount
'--- Does necessary initialisation
Private Sub Class_Initialize
set objExcel= CreateObject("Excel.Application")
sheetcount=1
End Sub
'--- Destroys the excel object once the class is destroyed
Private Sub Class_Terminate
sheetcount=0
If Not IsEmpty(objWorkbook) Then
objExcel.Workbooks(1).Save
objWorkbook.Close
End If
objExcel.Quit
set objExcel= Nothing
End Sub
