Way To Connect A Database Without Changing
Aug 21, 2010
So here goes, I am a college student and well in my college our lecturer has specific standards. She wanted us to use SQL Plus in order to connect to VB.NET but the problem is I don't have that program at home (as in that i mean the SQL PLUS program, i have VB.Net already just missing the other progam) and considering i have so much coding done using the program in college i can't change it now.of me going off and change entire code each time. I know there is easier ways and less code to do things properly but i'm afraid even when i'd love other ways that save in code the lecturer won't pass me on that, i even have to present it too so i need to know to explain things clearly.

I am using VB code behind in Visual Studio 2008 to process data but can't figure out SQLConnection problems. I copied and pasted the connectionstring for my database from the explorer properties window but when I paste it inside the parenthesis of SqlConnection() it gives me an error. Also if I name a variable " dim myconnect As New SqlConnection" in does not give me all of the methods or attributes that are associated with it. Is this a Express Edition limitation or do I need to make some specific declarations to get it to work. this is what I have so far
Dim
connectString As String
Dim myconnect As New SqlConnection()
[code]....
myconnect. If I try to put open() at the end of this it says its not a member of SqlConnection. I have a dataset but no way to insert into the database

I am trying to connect to a database in VB 2008 express the book I am using is for an older model of VB. The book says to go to view and click on server explorer, and then a database wizard should open. VB 2008 express doesn't have a server explorer under the view section. I know what code I need to enter into to the two buttons I have I just do not know how to open the wizard.
