VB 2010 Express - Randomize A Numerical Output To RS-232 With Speed Control

Jan 17, 2012

I have a USB device that is "seen" as a COM Port. It has eight channels, each require a single character to turn ON/OFF. It's a DLP-IO8 for reference. I have the COM port part working 100%.

1-8 turns ON each channel (12345678)

Q-I turns OFF each channel (QWERTYUI)

Truth table for device:

1 = Ch1 ON | Q = Ch1 OFF
2 = Ch2 ON | W = Ch2 OFF
3 = Ch3 ON | E = Ch3 OFF

[Code].....

a loop that I can still use the functions of the form (change speed or Stop loop).
a way to utilize Q-I to turn the channels OFF in random mode

I've been searching for a few days with little luck. I've tried Do Until, Do While loops and a few others.

I've only been coding for a few days now so go easy. Learning as I go. My form for reference

Ultimately I'm trying bring my PC Interface project up to date by going from a parallel port to USB.

Sending a "124" will turn on channels 1, 2 and 4.

I want to randomize ON/OFF with "on-the-fly" speed control.
cmbSPRan.Value is my NumericUpDown starting at 1 and ending with 10
RandomNumber = RandomClass.Next(1, 87654321)
SerialPort1.Write(RandomNumber)
Timer1.Interval = (cmbSPRan.Value) * 250

How To Speed Up MS VB.express

Feb 28, 2010

Is it possible to speed up VB.express on an older laptop? For example, is it possible to disable the announcements window for speed. It appears that the announcement window is just another webpage embedded in the program that would slow it down. Any other tricks to get vb.express up to speed on an older machine?

.net - Make Randomize Function To Randomize The Timers Intervals?

Mar 30, 2011

I cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

2010 Express & WebBrowser Control

Oct 14, 2010

I have some questions about the Windows.Forms.WebBrowser control.I have added this control to my project to be able to browse websites internally.First problem is that when I come into a webpage that contains JavaScript to open a new window, the control opens a new instance of iexplore.exe, tries to load the page in which the java script popup code initiated, but then prompts for authentication for a second time.Basically, I have to sign into one page to get to a listing of applications.I click on the application which in turn is just a URL to another page.The URL to the other page contains java script to open a new window.The new window opens in an iexplore.exe process, but re-directs me to the original sign in window instead of taking me to the correct site.If I do a msgbox on the cookie that is currently loaded, it displays my authentication information.How do I tell the new iexplore.exe processes to use the cookie that was stored in the webbrowser control?

I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

VS 2010 - Randomize Text From List And Place Into Another Textbox

Jan 23, 2011

I am creating a Map Rotation Randomizer for my Call of Duty clan, and I am having an issue with understanding how to randomize the text from the list and placing it into another textbox.

Here's what it looks like right now:
All textboxes are multi-line.

When I click a button for a game (CoD4, MW2, WaW), it places the map list into the left textbox like:
mp_bloc
mp_broadcast
mp_crossfire
etc.

When I click the button with ">>>", I want it to randomize that list and place it into the right textbox like:
map mp_bloc map mp_broadcast map mp_crossfire

Or if I click it again:
map mp_crossfire map mp_bloc map mp_broadcast
And so on. I think I need to create an array, but I've never worked with those before as I'm still new to learning programming. I'm not even sure what controls I need to put on the form for that, if it even requires any.

.net Express 10 Speed In New Project Versus Old Upgraded Project?

Feb 24, 2012

If I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.

What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.

Unhandled SqlException In VB 2010 Express Thta Does Not Occur In VB 2008 Express?

Oct 16, 2010

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."

I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).

Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
