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?
View 3 RepliesI 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

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 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

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.

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.
Is it possible to connect to a database on SQL Server R2 Express from Visual Basic Express? I am following a set of tutorial videos done in SQL Server 2005, but cannot seem to connect to create the database. I have created the database in SQL Server R2 Express, but cannot connect. Is there a work around?

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.
View 1 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Is VB Express 2010 slower to compile and run that older versions of VB Express? I've installed it this weekend and it seems a little sluggish on my quad core computer with 1 gig of RAM. I have VB Express 2005 installed for my students at school and it seems to fly just fine. Those school computers are older P4s with 512k of RAM.

It's probably just a case of me not looking in the right place or not seeing the obvious, but does anyone know if a machine with just version 2.0 of the .NET Framework should be able to run a VB.NET Express application which accesses a SQL Server Express database file? Or is there an additional requirement for a non-development machine to have some kind of SQL Server Express runtime component in addition to the 2.0 Framework?It seems to be counterintuitive to expect that a VB.NET application would be able to access any kind of SQL Server data without having some kind of SQL Server host component (Express or otherwise) installed. But then again, it seems just as counterintuitive that Microsoft would require the download and installation of the new framework as well as a separate database runtime in order for the average user to run an application with accesses a local SQL Server Express database.To me, it runs contrary to the whole concept of XCopy deployment to require more than just the application's files and .NET Framework for an application to run properly. But nothing I've read so far explicitly indicates that a user would require anything more than the app files and the framework to run an application which accesses SQL Server Express data. But...I can't get any VB Express applications which uses a SQL Server Express databases to run on any machine that doesn't have SQL Server Express installed.What am I missing?(Apologies if this isn't the right group to post this in.

currently writing a standard 3-tier (gui/business layer/data layer) winforms application in Visual Studio 2008.I have a form which has to load around 20 different sets of un-related data when it opens. My data layer returns seperate data readers to the business layer and each routine uses seperate sql connections (it opens them, gets a data reader, and then closes it).Now the problem i have is the speed the data is being retrieved. For a relativly small amount of data (around 100 rows of data combined) it's taking say 10 seconds to retrieve, parse into seperate collections and then paint to screen.My form is using controls from Infragistics and Component One and is quite heavy anyway
