Well, subject tells everything ...
I can't find what := does in VB.NET ...
Here's one example ...
SwitchDesktop(hDesktop:=p_lngHwnd)
Can anyone tell me ?
thanks

Are you telling me that ":=" is the same as "=" ?
But then why does it exist ?

This might be able to help you[^]. It is also possible that, that is VB6 syntax.

Sorry, couldn't find ":=" at that link. But thanks
And I don't know if it existed in VB6 ...

It's for named parameters. For example:
Sub ShowMsg(ByVal a as String, ByVal b as String, ByVal c as String)
MsgBox(a & b & c)
End Sub
Sub Main()
'Notice how a, b, and c are out of order.
ShowMsg(c := "!", b := " World", a := "Hello")
End Sub

Thank you very much, now I understand !

Unless I am mistaken, := allows you to pass variables by name vs. by position (example below is freehand).
Example sub: sub test (byval Value1 as string, byval Value2 as integer, byval Value3 as object)
Normal way to call by position: Call sub test("value1", 2, new object)
call by name: Call sub test(Value3:= New object, Value2:=2, Value3:="doh!")
Generally you see the := used in attributes.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

you can use it to assign values like you did in that function call...say some of those are optional and you want to assign directly to the variable name..

I know I should probably post this in the XML-forum, but since I code in VB.NET I posted it here. I have a problem: I am trying to save data in a XML-document, but when I try to do so, I get an error message telling me that special characters are not allowed. Since I do want to save special characters in my document, I'd like to know if there is a way around this, so that my program can input and output special characters.
Thanks in advance,

hi
I m Working on vb.net window application.
Actually I want to get the Session Data using Session id in my application.
please help me
thanks in advance

A client application doesn't use sessions, as it's a single user environment.
What is it that you are trying to accomplish?
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
I'm trying to save a dataset contents in a .csv or text file. The following code I've written.
My problem is "my.Computer.FileSystem.WriteAllText("d:\testcsv.csv", str.ToString, False)" in this line "my" is showing error always saying "my" is not declared. How to solve this problem.
Imports System.Text
Imports System.Data
Imports System.IO
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim str As New StringBuilder
SqlDataAdapter1.Fill(DataSet11)
For Each dr As DataRow In Me.DataSet11.stockm
For Each field As Object In dr.ItemArray
str.Append(field.ToString & ",")
Next
str.Replace(",", vbNewLine, str.Length - 1, 1)
Next
Try
my.Computer.FileSystem.WriteAllText("d:\testcsv.csv", str.ToString, False)
Catch ex As Exception
MessageBox.Show("Write Error")
End Try
End Sub

Which version of VIsual Studio (VB.NET) are you using?? The My namespace didn't show up until Visual Studio 2005. If you're using 2002 or 2003, this code will never work.
If you ARE using 2005, you need to import the Microsoft.VisualBasic namespace either in your code or in My Project settings, under the References tab.

What do you mean? Do you want to stop your application from showing up in the taskbar, minimize to tray or do you want to close the whole taskbar? If you want to do the last, as far as i know the only way to accomplish that is to close explorer.exe, resulting in loss of windows functions
