Hello Everyone, I really want to say a big thanks to codeproject because it has really help me big time.
------ HERE IS MY QUESTION -------
I was assign the task to design a web application that will send an AT command to a GSM/GPS modem requesting for it Location. The request is processed based on users specification like (Request Modem Location Every 30 Minutes or 1 Hour or Once a day)
So this is where i'm stock, How can i implement it. Here is an image of what the interface will look like. (Sorry i am unable to paste the image)
---Two radio button ----
--- Two Calender Control with it's Format Properties set to TIME---
--- A Text Box that will calculate the interval based on the value of the calander control ---
--- A Button Control to Request For the Modem Location based on the interval the Text Box control----

Please how can i do it.(The Problem is how to always execute an AT Command in every time interval selected)(A Friend gave an advice that i should create a .dll file for implementing the AT Command the Call it when the Button Control is click)

Any Help from you guys is welcome

Solution 1

you have to write a window service which will check the datetime and interval and hit the AT Command to your GSM/GPS Model.

You can't perform a scheduled task from a web application. Instead, you need to write a desktop app and use the Windows Scheduler to run it at the desired intervak, or you have to write a Windows service that will simply sit in memory and perform its scheduled processing on its own. I would go with the Windows service because it can run even without a user logged on.
