[3] again , VB.NET equivalent ?[Resolved]

[Pirate]

What's the replacement of Space function (VB6 Function) in .NET . It's used to return a string consisting of the specified number of spaces.

Private Const MAX_PATH As Short = 260
 
Dim sBuffer As String
sBuffer = [B]Space[/B](MAX_PATH * 2)

[Sheppe]

Uhm... Space.

Dim str As String
str = Space(500)

[Pirate]

No , that's imported from VisualBasic namespace . Did you actually read my post ??? . I said I don't want to continue using Space function , otherwise I want something similar to it by string or whatever obj . Pure .NET way .

try this

Imports System.Text
'/// as usual at the top.
'///////////////////////////
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim strString As New StringBuilder(256)
        strString.Append("A", strString.Capacity)
 
        MessageBox.Show(strString.ToString)
 
    End Sub

[dynamic_sysop]

here's a better example , using an api call but , showing how the stringbuilder works inplace of the Space thing from vb6 :

Private Declare Function GetClassName Lib "user32.dll" Alias "GetClassNameA" (ByVal hwnd As IntPtr, ByVal lpClassName As StringBuilder, ByVal nMaxCount As Integer) As Integer
'/// i modified it to StringBuilder ^^^
'///////////////////////////////////////////////
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim strString As New StringBuilder(256)
        GetClassName(Me.Handle, strString, strString.Capacity)
 
        MessageBox.Show(strString.ToString)
 
    End Sub

Can't this be done with string class , because I'm getting a lot of errors in the subsequent code . They're all based on string objs .

Thanks .

[dynamic_sysop]

you can make a string have a capacity by doing something like this .....

<VBFixedString(256)> Public strString As String

but it'd have to be in a public area.
however the correct .NET method is StringBuilder and it's far faster than String.

[Pirate]

I converted stringbuilder to string but this won't be converted ! How the heck can I modify this to return string ??

sBuffer = CType(sBuffer.ToString.Substring(0, lNullPos - 1), String)

[Pirate]

ToString , CType , DirectCast won't work either . . Seems I'm stuck there no other options left ?

[DevGrp]

Pirate it seems to me that you are using a conversion program. Anyway try this.

sBuffer = (string)sBuffer.ToString.Substring(0, lNullPos - 1);

[Pirate]

error :
'String' is a class type, and so is not a valid expression.

No I'm not using any program . But why you said that ?

[Pirate]

We're here talking about VB.NET code .

[DevGrp]

Nevermind what I said. I thought you wanted it converted to C#.

[Sheppe]

Sorry 'bout my first response, Pirate. Try this:

Dim str As New String(" ", 25)

That will initialize a string object with 25 spaces.

[Pirate]

It doesn't work .

[Pirate]

This works

Dim str As New String(" ", 260)

Thanks Sheppe

You can also use padleft and padright if you need to add spaces or any character to an existing string.

Const MAX_PATH As Short = 260
        Dim str As String = "Something" 'or String.empty
        str = str.PadLeft(MAX_PATH * 2, " ")
 
        MsgBox("'" & str & "'")

[Pirate]

I don't want to add spaces , I wanted to get a string consisting of the specified number of spaces (260 chars) .
