Serial Port Programing For Digital I/O?
Aug 27, 2009Im an electrical engineering student, and I am trying to utilize the serial port to give me high and low digital states. What i want to do is simply turn on an LED or turn it off. the basic gist of what I have been trying currently is that on a button click, serialPort1.DTREnable = enabled or disabled, indefinitely until the next button click.
So far, I have only been able to get the LED to momentarily flash... It seems to begin in an active state flash off, then immediately, return to its active state. I am using Visual Studio 2008. Can I use DTREnable to generate on/off states by enabling or disabling the pin? Is there a tutorial somewhere for electrical engineering applications using visual studio 2008?
Object Oriented Programing, Where To Draw The Line?
Jul 10, 2011I created a project in Excel-VBA (wich I'm also new at) that connect to a SQL. It retrieves data, puts it in arrays, calculates, writes it up nicely and mails it to a mailing list before it closes itself down. This works when Excel is stable on the server, which it is not. Therefore I'm set on rewriting it to VB.NET (just have to learn it first).Project:To build this project in VB.NET I wanted to try and make it Object Oriented (OO). I have read that OO is when I create a Sub or Module for different tasks. Are there any advantages in learning/doing this from the start? I plan on creating Subs for almost everything, and then call it from a Main sub.
Too much OO?:
These are the modules I plan to create (and call)

Uses Of Arrays In Programing - Mathematical Concept Such As Fibonacci Sequences?
Feb 7, 2012I am trying to get a better understanding of the uses of arrays in programing, and have been wondering why do programmers use an array when working with mathematical concept such as Fibonacci sequences? why are arrays so prevalent in coding now a days.
View 3 RepliesASP.NET UpdatePanel Timeout And 500 Errors With Custom Errors?
Sep 23, 2011I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

Jul 3, 2011This is my first time writeing a program and i am stuck. i am just looking for were i should go next. i can't figure out how to write in code for the days in the getDay function.
Write a program that computes the cost of a long-distance call. The cost of the call is determined according to the following rate schedule:
a. Any call started between 7:00 A.M. and 9:00 P.M., Monday through Friday, is billed at a rate of $0.30 per minute.
b. Any call started before 7:00 A.M. or after 9:00 P.M., Monday through Friday, is billed at a rate of $0.15 per minute.
c. Any call started on a Saturday or Sunday is billed at a rate of $0.10 per minute.
The inputs will consist of (1) the day of the week, (2) the start/end time of the call, and (3) the length of the call in minutes. The output will be the cost of the call. Input will come from the user and outputs will be displayed via the console window.

C# Dont Reference Sqlreader In Client Portion Then Where?
Oct 30, 2009Assume I have a form that has say 5 text boxes and I need to pull some data from a database then set those 5 text boxes with that data.So assume I have 3 basic layers: the code behind for a default.aspx page a BLL class that contacts the DAL and a data access layer (DAL)But I've heard and read that the default.aspx page should not know about sqldatareader, in fact you probably dont want to add the sqlclient namesspace to the default.aspx code behind page. [code] Then the BLL would simply call the DAL to call a stored procedure in SQL Server and do a CommandObject.ExecuteReader, get the results pass it back to BLL and BLL would then send it to the code behind page of default.aspx.I can provide full source code if that doesn't make sense. My question is if its bad that default.aspx actually declares and knows about an SQL Data Reader then what is the better way to do this? What datatype should I be using to avoid having an sqldatareader in my interface code ?

View 3 RepliesOledbdata Or Table Adapters Dont Update Database?
Jun 22, 2010I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

View 2 RepliesProgram Dont Work If Not Change CPU Type To X86 In Project Properties
Dec 13, 2009Each time I create a program, if I don't change the CPU type to x86 in the Project Properties, Compile, Advanced Compile options, it doesn't work. For example, if I hit the drop down button on a combo box, there will be no data, but after switching to x86, there is data. How does changing the CPU type affect how others (such as when its being graded) view the program? If the program is not run on an x86 system, would it appear to not work then?
View 1 RepliesUnhandled Exception Trap - Dont See View Application Events Button ?
Oct 21, 2009I found some threads talking about this.. but when I follow the thread on where to do it.. it must be talking VS2005.. cause on vs2008 in project properties -> application tab-> I dont see View Application Events button. so I assume its moved in VS2008 ? I did find some code I guess to do the same thing.. but I wanted to make sure I do it correct.. since I have an app that a client is running and they keep getting framework exceptions and I have no clue where its coming from.

Visual Studio 2008 Log4net Multiple Modules, Same App.config Different Loggers, Dont Work?
Aug 20, 2009I have 2 console apps projects in the same directory but different projects. There is some common code in the App_Code directory and a common app.config which gets build into seperate .exe.config files.One module (VScanDemonStarter) starts up and writes to one logger with its own appender going to a seperate file. It uses an process.start() to execute the other module (VScanDemon) in another command prompt hidden window.When I run VScanDemon by itself it puts entries into its log file. When I run VScanDemonStarter it puts entries into its (different) log file, the VScanDemon log file gets created, but no entries. I can see it is executing because some files get moved from one directory to another. Just no Log entries.
