Today I face really strange issue, when I tried to download filewith extention .xlsx and browser redirect me on 404 Page not foundpage. My belief is whenever IIS (webserver) found file is not scriptfile then it will let browser to download the file but in this case ittook me to "Page Not Found" page.
I have done googling for this and Solution is really simple. We require to add Mime type 'application/octet-stream' in IIS.
I was just working around to get list zip code within 25 miles of radius for given address. I have database table for Zip Codes with below columns.
I have created MS SQL function which returns sql table object with list of all zip codes within specified radius in which you might interested.
