how to add system.barcode.reader to web.config

dear all

 

i have a MK500 device which will read barcode and display the price from SQL database using .NET windows CE mobile application

 

now one of the client need web based instead of native application.

 

i made a .aspx web site for reading barcode entered on the text box and display price. - this is also working fine from browser of MK500.

now i need to open the reader/scanner on  the device while the .aspx opens and read the barcode to aspx page from the reader/scanner

 

i copied the dll files (symbol.dll, symbol.barcode.dll,symbol.standardforms.dll) to web site bin folder.

 

now i am getting below error while running the default.aspx page (both from device and desktop)

 

Could not load file or assembly 'Microsoft.WindowsCE.Forms, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes' or one of its dependencies. The system cannot find the file specified.

please advice
