Visual Basic .Net Quiz

[Tewl]

Okay I'm bored and just wanted something to do so I thought I'd ask a few questions about vb .net an let everyone see if they could answer them. Feel free to add any questions of your own I will answer these questions when I get home from work tonight.

[General VB .Net Question]
What is the difference between referencing and importing?

[ADO .Net]
What is the new alternative to recordset. ( Hint: it is connectionless )

[IO Question]
In vb net there are now classes ( in the System.IO namespace ) for reading and writting files. Name these classes.

[Arrays of Objects]
In vb 6 objects ( buttons, classes, usercontrols ) had an index property in which you could create a control array. In vb .net this is no longer available. Explain how you would create objects dynamically an how you would reference to each one.

In VB6 u used to do

Form1.Text1.text = "TExt"
from Form2
this is the easiest question. even easier than Tewl's

How can u do this in VB.NEt
Note: u can do the same in vb.net as in vb6

have fun

[Tewl]

Well the answer to your question would be something like this.

You must either declare a global instance of form1 that form2 can get access to or pass a reference of form1 to form2 ( eg. pass form1 in the form2 constructor ). The syntax is basically the same.

In addition in vb6 you could do Text1 = "test" because the text property was the default property in visual basic .net you must specifiy the property because default properties no longer exist.

[General VB .Net Question]
Q: What is the difference between referencing and importing?

A: Referencing an allows u to have access to the libraries in the namespace but if you also import the reference you do not have to type out the full namespace ( eg. System.Windows.Forms.Textbox )

[ADO .Net]
Q: What is the new alternative to recordset. ( Hint: it is connectionless )

A: Dataset

[IO Question]
Q: In vb net there are now classes ( in the System.IO namespace ) for reading and writting files. Name these classes.

A: Stream, Streamwriter, StreamReader, BufferedReader, TextReader, TextWriter, StringReader, StringWriter, BinaryReader, BinaryWriter

[Arrays of Objects]
Q: In vb 6 objects ( buttons, classes, usercontrols ) had an index property in which you could create a control array. In vb .net this is no longer available. Explain how you would create objects dynamically an how you would reference to each one.

A: There are several ways of doing this oen of my favorites would be to create a new object ( object myobject = new myObject ), set all the paramaters, probably set the tag or text property to somethign i can use to identify it uniquely, then add it to an Vector
