What is the vbUnicode equivalent in .NET?

what is it? i am needing for this API:

VB Code:

Private Declare Function DoFileDownload Lib "shdocvw" _
    (ByVal lpszFile As String) As Long
 
Private Sub dnload()
   
   Dim sDownload As String
   
   sDownload = StrConv(Text1.Text, [b]vbUnicode[/b])
   Call DoFileDownload(sDownload)
   
End Sub

anyone could help me converting this to .NET code..?

Well, here's what I came up with after messing with it. Notice that I changed the API declaration. I'm not sure if there's an easier way, but this does work:

Code:

---

    Private Declare Function DoFileDownload Lib "shdocvw" _
    (ByVal lpszFile() As Int16) As Long

    Private Sub dnload()
        'You can change this to take from a textbox again if you want
        Dim sDownload As String = "http://www.yahoo.com"

        Dim A(sDownload.Length) As Int16
        Dim I As Integer
        For I = 0 To sDownload.Length - 1
            A(I) = AscW(sDownload.Chars(I))
        Next
        A(sDownload.Length) = 0
        DoFileDownload(A)
    End Sub

tks all check it, i saw msdn and there is no unicode in .NET :(

i am geting this error:

C:\Documents and Settings\JBRANCO\My Documents\Visual Studio Projects\dev4\main.vb(257): Value of type '1-dimensional array of Short' cannot be converted to 'String'.

I told you I changed the api declaration. You're going to have to change it in your app, too.

Judging from your error, it looks like you forgot to do that.

ah ya sorry i suck
-_-

working =)

Go read up on the String class in the MSDN help.

The ToCharArray method copies the characters in a string to a Unicode character array.

EDIT:

Oh, and you shouldn't use unmanaged code with .NET. It slows things down quite a bit. Rather than declaring your DoFileDownload procedure, you should use the System.Net.WebClient class.

Actually, Strings in VB.NET are already in unicode. And the Char datatype always specifies a unicode character. The problem is that VB automatically converts strings and characters to ANSI before passing them into an API function. This means that using ToCharArray doesn't help at all.
