after being disappointed with VB2010, and with the lack of vb support for windows 7 phone, I thought I'd be happy now that vb is going to be supported after all.So, I downloaded the trial version of vs 2010, to run these new tools.Several hours later it finishes installing, and I start a new project only to run into the error: Error: this template attempted to load component assembly "Microsoft.VisualStudio .SmartDevice.ProjectSystem.Base".

View 6 RepliesI am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

Question: I created an ASP.NET web application. Now it originally was meant for deployment on a webserver.That is working, so, so far so good.My question now is: Is it possible to deploy it as a desktop-application, too? That is to say the installer installs some kind of server, plus the web application, configures the server to run this application on a localhost URL, and then creates a link in the start menu/desktop, where it opens that url (website, the application) on localhost in a web browser?
I think it should be possible, though the server wouldn't be IIS, because this is a windows component which can't be separately installed. Is there anything like this already out there The nonplusultra would be that it only starts the server when you click on the shortcut.
The system should not insert selected records from my datagridviewcheckboxcolumn if it's already existed in the database.It's like when you're registering online. If you're username/email address already registered,it would inform you that youre username/email is already registered and the site would ask you to change your username/email to new ones.The difference in my system is that i have 2 datagridviewcheckbox columns not just textboxes . Parent and Child in the datagridview. What i want to happen is that once the Code has been registered as Parent it cant be registered again as Child anymore.
