I had written an app that runs at ever login (win7). So as it is running I load 2010 Express and try to test some things, but it comes back and says "The operation could not be completed. The Process cannot access the file because it is being used by another process."How is that possible when the 2010 Express should be fully contained? I have even named it completely different from the originally application. Am I missing a setting?
View 8 RepliesSometime when I press the run (F5) Start debugging button it does nothing. Often when I have jsut run it and made a quick correction. If left for a while it will then work! Have tried it with simple and complex projects.
Using W7 x64 - never had this problem with VB 2008 express.
I'm testing my Visual Basic .net application by running it in Visual Studio express.Sometimes it runs OK, but other times I get an exception (details below, if useful). I'm not sure why I get the exception as the particular part of the application that I am testing re-uses code that works OK for other features.
What should I check, what would give me a hint as to the root cause. Things I tried so far are: Rewriting some of the code to be more robust. The outcome of this was that this approach was getting out of control - I was correcting everything. I made changes such asing alternative libraries (e.g. replacing CInt with convertTo etc). Some lazy declarations, but it occurred to me that there was no problem with these with the code before my changes. And every change I seemed to solve uncovered yet another problem, another different exception So I thought something must be fundamentally wrong with my installation, and a search found discussion group posts from people experiencing something similar. The suggested remedy would be to re-install the .net framework. So I did that and the problems still occured.
Any thoughts on approach to get to the root of the problem? I'm not asking for a solution but some fresh ideas would be very welcome.

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.
View 3 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).

If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.
View 1 Repliesthis is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

Is it ok to install my VS 2010 Ultimate even if I already have VB 2010 Express Edition? or should I uninstall the express edition first?
View 3 RepliesHere are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?

View 4 RepliesI am learning VB for the moment. I want to copy/paste code from a PDF to Visual Basic 2010 Exppress, but if i paste the (structured in PDF) code to VB, i get 1 long string of code and need to restructure it by entering after each line. Otherwise VB gives me a lot of errors. This is a time consuming work. Isn't there a way, VB puts the code in the right format?
View 4 RepliesPrior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.
Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.
Is this a bug in VS 2010, or is there a switch/option that controls this?

View 7 RepliesI 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.

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.

View 2 RepliesI'm just starting to use VS 2010 - not sure if this was available in VS 2008 - but I was reading about the Hosting Process you can start for debugging.This allows you to call methods and jump into breakpoints in them without starting the whole app running.
