I have written a simple utlity in VB 2010 Express that reads data from an Access database and displays statistics graphically.It work fine on my development machine running XP. But on another XP machine I get a System.InvalidOperatinException erro on program startup.

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

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've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.

I am complete newbie to VB express. I have created a simple windows form that opens programs using menus and so on.Works great using the Process.Start on windows apps (word, excel, etc.) but I have some very old programs that run in DOS I am also trying to open that do not work when using the Process.Start method.
I am able to get the command prompt box to open up and in the title bar it shows the path of the .exe program I want to open but the actual program is not opening.

I've been in VB express for about tree weeks, formerly of VB 5 for about 10 years.
I need to open a form on top of the form of another application, that is, making the other applications form its parent. The title on the applications form can change, so searching for the form by name won't work.
I'm also curious, can you start a vb express application without opening its form? Like in Vb5/6 you could start in Sub_Main?
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.
I have been using Access 200 as my database of choice with Visual Basic 2008 Express.I am trying to start usingSQL Server Express but having a difficult time with it. All of the instrctions I have tri9ed seem to be written for someone who already knows the answers. Here's my problem.I wrote a program using Access, with one table and five queries and it works fine. Using that program as a baseI created an SQL Server database within Visual basic. Naturally I changed my code to reflect SQL rather then OLEDB.When I try to run the program I get an error message telling me that the database is not registered. When I use the SQL Server Management Studio Expres, it shows my database by give a big message that the database is not registered.

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.
View 7 RepliesInitially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).
