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.

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 [Code] .....

How do I take the input of a text box as as string and write out a procedure for a button that takes the input and outputs a variable in the list box. For example i want to assign various values to strings such as the price of a chair = $10 and price of table = $40 . How do would you write it so that when you click the button it takes the word chair in the text boxs and outputs a value in the list box.
I have a codes that calculates DownLoad speed and UpLoad speed kb/s. I would like to implement this kind. I also want to put such kind of graph. Any article or links where can I start building my own like that.
I am checking for empty string values, but how do i see for the Quantity text box if the user chose only numerical values after the empty string. For example...
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.

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?
im using a WebBrowser control to auto fill a form in a page... i can access some properties of the <INPUT> html object, but when i try to set the Value property of this object VB fails and send me an error... i tried the SAME CODE in VB 6 and functions perfectly..Im using VB NET EXPRESS 2010

I am attempting to write a speed/distance calculator using visual basic 2008 express edition. I have gotten the program to do most everything I need but am having some difficulties and have been trying to fix them for 2 or 3 days now without any success. 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
Can someone tell me if the functionallity to control a parallel port in MS VB 2010 Expess exists? I was expecting to have to add a reference such as the microsoft comm control 6.0. However this reference does not appear in the list. Everything I search for references .net 2005/2008.
controls mainly an indexed picturebox control. In VB 4, 5 and 6, I could make a picturebox(0) indexed, but in VB Express 2010 I no longer see this option in the picturebox properties window how is this accomplished in VB Express 2010.
I'm trying to make a game with a friend. We have 4 sprites (pictureboxes)and we're trying to make them change tab order based on a value assigned to their variable.
I've just rebuilt my PC and have upgraded to visual web developer express 2010. I have imported my projects which use the charting control quite a bit. Unfortunately my projects are failing to run. In design view the control is now showing as "unknown server tag asp:chart". I can see the Chart control in the data tab in the toolbox but it is greyed out.
I'm having a bit of an issue with this program I have been working on for my class. It's a future values calculator, that takes a single data type, decimal data type and a integer data type does the formula and then spits back out the Future value. What i'm having difficulty with is converting the string over.

I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. 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.
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.
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.

can i in some way change the power that the usb sends to a usb device?i want to connect a computer fan to the usb and control the speed is this posible??
How do i exactly check internet connection speed.I have searched around google and found out a method w/c will Download a file like 1mb size, then it will calculate the speed.
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.
