VB 2010 Express - Randomize A Numerical Range 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)

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.

Q-I turns OFF each channel
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

Asp.net - Randomize Numbers Without Using A Range I.e. Min And Max

Jul 5, 2010

Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.

i.e. Table Data
ID | Name
4345 Mike
3456 Lee
4567 John

There will be many more names but for this example you could use 3 or 4 etc..

How To Speed Up MS VB.express

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?

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.

Variable For A Range In An Excel Chart Output

Sep 29, 2011

So I created a loop that collects data from the user that runs for a time dictated by the user. It then stores all the data in excel and outputs a graph.The problem I am having is that I cant seem to figure out a way to set the range of the graph for the points taken.since it runs on a loop i have i = i + 1.where the the output into the excel file sequentially writes to the next cell [code]which doesnt seem to work like I would have hoped.Also, there is one other thing that my program keeps doing that I cant seem to figure out.One of the outputs to the excel file is decimal number, it shows perfectly in the textbox, but when I export it to excel it rounds it to the nearest whole number.[code]

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?

Will somebody, anybody please tell me how to fix the problems.The calculator should display the distance traveled when the speed and time are entered. This is the only major requirement. However, It needs to have all info input via a list box with popup windows displayed for speed entry and then again for time entry. I would like a label outside of the list box to show "Total Distance Traveled" and I would like the list box to display the following information

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.
