• Visual Studio Express Editions Problem with Absolute Beginner's Video Series Lesson 7 - worm?

  I have been using the Absolute Beginner's Video Series for Visual Basic Express and love it. For Lesson 7, however, it never gets past 83% downloaded. As a result the seek button doesn't work.

• .NET Development DB Changes not committed in VS/SQL Server DB

  I am brand new to vb.net and Visual Studio. I am following a series of lessons where I am supposed to be able to connect to a SQL Server Database bind the db to a form and then edit, add and delete records from within the form. When I run the project everything appears to work correctly, I can change the table data, add or delete rows but once I close the project and look at the underlying data, none of the changes are reflected. When I re-run the project, the data is just as it was before I made the changes. I can edit the data directly in the tables and it works as you would expect. I'm sure that this is something bone-headed that I'm m ...Show All

• Visual Basic Getting Underlying Data From Databound Controls

  I have a form with databound controls on it. So I am using a datasource, a tableAdapter and a BindingSource. My question is, what is the "proper" way to get underlying data from the current row through code. For example, say I want to get the ID field for the currently visible row that is being displayed in the controls on the form. Also let's say that the ID field is not represented by a control. It is in the data, but not bound to any control. The dataset is called DSEfaxCentral The table is called tblFaxes The binding source is called tblFaxesBinding Source. As of now I am using this method to get the ID field for the current ...Show All

• Visual Studio Express Editions What books to get

  I have looked at the local book store for books on programming. There seems to be a selection of books on VB6 and also on VB.Net. Which would be a better choice for me to get in order to learn the Express edition Any major differences I should know about when reading one of those that I need to keep in mind when I'm applying it to VB Express Thanks! Whatever book(s) you get, get those that cover VB2005. The other versions, won't help you with VB2005. There are a lot of new books for VB2005 and even some that include a copy of VB2005 Express Edition. I haven't used but one book on VB2005 and that was Introdu ...Show All

• Windows Forms The v2 DatePicker doesn't support null databinding (bug?)

  The following code (which is a simple test windows form - visual studio team 2005 system beta 3 refresh) demonstrates what I believe is a bug in the DatePicker control. When a datepicker is bound to a binding source set to an object, properties of type DateTime that are null are not updated when the user (at runtime) changes the date. This is a real pain; and, frankly, makes the date picker useless to bind to database-derived datatables which could contain dbnull. Thank you in advance for your help. (also: why is it called datetime picker when it does not pick the time ) Correct. The DateTime picker does not support null ...Show All

• Visual C# AccessViolationError, how to fix?

  Using C# express beta 2, I'm getting an AccessViolationError on even very simple forms. It was working fine last night, now I can't get any new form to work. IE, I go to New Project, Windows Application. Add a single Label and click debug. It builds with no problem, but when it goes to debug I instantly get the exception.
