SMS Programming in C# Part 1

It's quite difficult to find resources regarding SMS programming with C#. Well, I have gathered through some other sites on how to program mobile phones (various models including Nokia N96). Before I write about C# (I'm using C# express 2008), let's have a look at the basics first. This first part will talk about connecting to your mobile phone and testing its connectivity.
  1. Be sure that you have your mobile phone driver installed.
  2. Connect your mobile phone
  3. To test the connectivity of the phone and whether it responds to our commands, let us try hyperterminal. In XP, Start->All Programs->Accessories->Communications->Hyperterminal.
  4. Specify the Name of the connection.
  5. Choose the Communications Port (Usually, the mobile phone will from Com1 to Com3. To know which port the mobile phone is assigned to, go to Control Panel->Phone and Modem Options->Modems. It will list down all the modems attached to your PC).
  6. Specify the Bits per second, Data bits, Parity, Stop bits, and Flow Control. You may leave the default values.
  7. type in "AT" (without the quotes) to test the connectivity of the device. If it responds with "OK" then you can communicate with your device. Mobile phones have built-in AT commands that we can use to manipulate different functionalities.
Various AT commands are available for testing. Google them up, and there are many sites that give info about each command.


A good phone to test will be Nokia N96. You'll be sure that it will have the minimum (well not only the minimum) requirements for your programming needs. The best Nokia N96 deals can be found over the web. Best deals are on October.

Adding a Footer to the DataGridView component

I have been searching for sites and forums that would give me a any hint on having a footer on the .net DataGridView control. It was frustrating. I found some, but not what I was looking for. I use windows forms. It would have been easier if I was into web. I decided to create one for myself. It's not complete, but it works with me. It needs improvement and I hope that some programmers who might pass through this blog will help me with it :D. Limitations: Cannot set Footer values during design time. Can sometimes hide a row when scrolled to the last item in the grid. What I did was just create a user control that inherits the DataGridView control and add a StatusStrip to act as the footer. public partial class MyDataGridView : DataGridView { public StatusStrip Footer { get { return (StatusStrip)this.Controls["Footer"]; } } private bool _footerVisible; [Browsable(false)] /// /// Sets or Gets the va...

Using Crystal Reports 10 with C#.net and Firebird

C# express doesn't include a report designer or viewer. Reports however, is very much needed when creating a business software. Since C# express doesn't include a report designer, we need to find other means. One is to use a free report such as MyNeoReport. This however may not work under many circumstances. The other alternative would be to use a proven report engine and designer-Crystal Report. Crystal Report has been used by many developers (in our city). However, using a free programming language and IDE, and a free database is very limiting. Not much information can be gathered on the net either (with regards to reporting as of this writing). Here's a way to use Crystal Reports using Firebird database and C# Express as software development IDE: Pre-requisites: C# Express 2005 EMS SQL Manager 2005 for InterBase & Firebird Lite Crystal Reports 10 Create the following database: Name: TestDB1 Tables: TESTTABLE1 Columns:  ID - PK, INTEGER,AUTOINCREMENT DES...

How to cheat blog polls

Ok, I really need to post this. Many bloggers put polls on their blog sites and rely heavily on the results that they give and some even draw conclusions based on those data. The problem is that they don't check where the data those polls are generating are stored. Many polls don't even record the voter's information. Well to those of you who want to cheat polls (I mean blog polls. Some polls are really reliable), here are some points: 1. These polls don't store your IP address nor your MAC address, how then do you think are they checking for flying voters? COOKIES! 2. Now you already have an idea. Now try to vote to a blogger's poll then clear your cookies and refresh the page. You'll be able to vote again. 3. If #2 doesn't work, there's a big chance that your voting data is stored on internet temporary files. Now you know what to do. Delete those files. 4. If #3 doesn't work, then your data might have been stored elsewhere. You might want to use a ...
