I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

View 10 RepliesI created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?
I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

I am writing a program to try and centralise alot of data i have on my network so i can use them as templates and guides. My intension was to have an easy to browse program with links in the program which open the particular file (eg. Word document, excel spreadsheet, pdf file etc).I have very limited programming knowledge and in my research i came across this code in VB which allows the program to open the determined file:

Dim procstart As New ProcessStartInfo("explorer")
Private Sub btnProgTemp01_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProgTemp01.Click

I upgraded a working VB.net windows application from VS2008 to VS2010 (a fairly simple form to process some data) and I get 15 warnings "Load of property 'X' failed" where 'X' refers to what looks like system variables like OutputType, StartObject, RootNamespace, AssemblyName, Option Explicit and so on. I also get two errors pointing to the Form1.Designer.vb file which I is the DesignerGenerated file saying that "My' is not a member of '<Default>'Originally I just used the upgrade wizard, resulting in these warnings. Next I tried creating a new project and adding the relevant files using the VS "Add Existing" function. I have also looked for answers in the forum and on-line but found none. This has got to be something simple I am overlooking.
