Probably because you haven't installed something. You can find it here[^].

Argument should implement 2 or more interfaces

24-Mar-07 7:24

It's System.Data.OracleClient in the list of .NET references. You do not have to add anything that's part of Oracle ( and unless it's a .NET or COM dll, you couldn't any how )

Hi,

Is it possible to specify that a sub/function argument should implement two or more interfaces?

What i mean is something like this (of course this doesnt work):

Private Sub DoSomething(ByVal x As {IFirst, ISecond})
    'Do it
End Sub

Thx,
Banjobeni

No.

If ISecond inherits IFirst then you could accept anything that Implements IFirst, which would also include anything that implements ISecond. However you would be limited to only the methods and properties found in IFirst. If you needed access to properties/methods found in ISecond you would have to test the object to see if it could be cast as ISecond and if so act accordingly. If those are completly seperate interfaces then no it's not possible.

What is the easiest way to test if an object can be cast as something?

Christian Graus24-Mar-07 7:25

24-Mar-07 7:25

if (myOb is IMyInterface)
{
}

or

IMyInterFace myInt = myOb as IMyInterface;

if (myInt != null)
{
// It worked
}

And in VB.NET?

Christian Graus24-Mar-07 7:32

Sorry, I don't know the VB.NET syntax for 'is' and 'as'. I don't use VB.NET, ever.

But you know that this is a VB.NET board, right? If I needed C# code or any of the .NET languages, i would have posted it there.

Did you know that both C# and VB.NET both target the .NET Common Language Runtime?

Did you also know that if you look on MSDN for the docs on any class, property, or method, or function, there's always an example in BOTH languages? Thousands of examples serving as Rosetta stones!

If TypeOf objectName Is interface Then

Yes, but I can answer most questions here, because they relate to the framework.

If Dave is on the job, I'll hang back, he always knows more VB than I do.

Given that I don't use VB at all, it's arguably faint praise, but it's not meant that way....

Comming from you, that says a lot! Big Grin | :-D

I know VB is kind of like a killer disease, but it's one I'm immune to! You actually CAN write good code with it, it's just rare to find a person who's been using it AND knows how to write code! Laugh | :laugh:

What do you mean - a dictionary as in a way to look up meanings of words ? I guess you can just make a table with two columns, word and definition.

print preview in vb.net 2005 Window Application

24-Mar-07 6:46

I bet you do. However, in the real world, people tend to use these forums to ask questions when they need help, not when they want the project written for them. Well, that's not true. The people who do that, tend to get help, and those who say 'I need this code' tend to end up disappointed.

It's kind of trivial, why don't you try and ask when you get stuck ?

Even if your question made sense, this is a place for people to ask for help, not for people to post their requests and have their work done for them.
