VB SQL Express 2010 - Compact .sdf File
Jul 22, 2010
I created a SQL Compact Edition .sdf file in VB 2010 Express. I set the first column in the table as a Primary Key. But can I make use of it or am I limited to scrolling all the way through the file until I find the match I want? I managed to use a primary key with a SQL server .mdf file using the FindBy statement, though as a beginner, didn't really understand what I was doing so resorted to the more simple sdf file format to get me started. Goodness me there's so much to learn about data handling, it took me days to find out I didn't need a .Net provider in the connection string for Compact Edition.

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

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.

This seems really dumb but I go to this site - [URL] and click on the link for Visual Basic 2010 Express, select English as the language and I get the file vb_web.exe. The file installs Microsoft Visual Web Developer 2010 Express. All of the tools in it seem to be for web development only.Where is vb express 2010 download for creating Windows forms, console apps etc.? (or am I missing something "basic" -- sorry about that -- regarding how the 2010 version works?

Is there a limitation to the size of program that you can create in VB 2010 express? I ask because I am writing a program that asks a user for input, then checks that input to a list of possibilities in case statements.My code is a little over 5000 lines.

I have a VB 2010 Express application that uses a .mdb and a .xml file. Both files are part of the project. I am pulling my hair out to try to figure out how to make sure that these two files are deployed with the application. So far, I have only been running in Debug mode, so I'm focused on making that work.
When I click on the Application Files button on the Publish Tab of My Project, both the mdb and xml files are visible. I have tried setting both files to Data and Include. In either case, the mdb file is copied to the bin directory when I try debugging my application. However, the xml file is not copied no matter which option I select.
How can I get the xml file to be copied into the bin directory like the mdb file?

I have a single table in a SQL Compact DB (*.sdf) and a Datagridview. When I put the datagridview on the form I connected it to the table in the compact DB. I also have a few button that, Deleted and Add a entry. Delete button obtains the selected datagridview row and resolve the record ID. It then deletes the record in the database. The record gets deleted but the datagridview does not show the update unless I restart the debug session. I make teh same cal to:
Me.TblTableAdapter.Fill(Me.Database1DataSet1.tbl) which is called when the form load that fills the datgridview..

I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.

I'm sure there is an easy answer to this, and it may be "no," but is it possible to create an install file in VB Express 2010 and have that file deploy additional .exe files?
I developed a windows form program that calls fortan routines (in seperate .exe files) for different purposes. I would like to create an install file that deploys not only my VB program, but all of the supporting code.
Is this possible with VB Express 2010? I tried to search for threads about this, but didn't find any that explicitily answered this question.

Greetings, I'm a little bit confused about SQL Server Compact behavior.I have a small app that uses a small sdf file located on a network share.The problem is that while the app itself is working perfectly well using the connection string that points the location of the sdf file on a network drive, when I try to open the same sdf using the Server Explorer I get this error:
SQL Server Compact does not support opening database files on a network share.Obviously, if the app IS working it does indeed support network shares, then why Server Explorer cannot open it?
I copied the database file to a local drive but it's not very convenient. What might be the problem?

I am trying to compact a Access 97 MDB file. I have found and tried the following code
Private Sub CompactDB()
Dim jro As JRO.JetEngine
jro = New JRO.JetEngine()
jro.CompactDatabase("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>", _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>;")
MsgBox("Finished Compacting Database!")
End Sub
This codes works and seems to compact the file and it appears in the destination folder but when i try to open the new file i get an error "Unrecognized database format 'DATAPATH'"Is there something i am doing incorrect? the database file sizes range from 5Mb to 100Mb+

I need to have two pieces of software, made in vb where one encrypts the contents of a .txt file, and the other decrypts it, and then picks one word at random and displays it each time a button is pressed, but never displays the same word. Or, if there was a way to hard code it into the program as there is only 5 words that would be better.

I have been reading about ADO, SQL, datasets, data adapters etc and have gone into information overload. My next step is to create a simple data file of my own that I can manipulate, update, sort etc in VB Express. Do I need another piece of software? I read about MySQL, which I understand is primarily used to access databases on the net, but can that be used to create a simple local data file on my PC? Can you simply hard code something in VB Express?

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 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.

Initially 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).
