Excel template is getting opened unncecssarily--- vb.net 2008

[Pankaj Garg]

I have an excel template, from this template i copy the worksheet and save it to workbook. I initially created an excel.application instance

xlsApp1 = CreateObject("Excel.Application")

then , i open this template file

temp = xlsApp1.Workbooks.Open(ExsTemplate & "sheet.xls")

i am presently in debug mode and breakpoint is on the above line. and right after this i open an excel sheet by double clicking it which is lying in my hard drive. This opens the template file also. This is the problem. Can u tell me how should i avoid this problem.

You problem isn't clear. Are you asking for a way to stop someone from opening a file? Because I don't think you can do that. Or are you getting an error because the file has been opened by the user? In which case, what is the error?
