Why not just make it ReadOnly?

I have created a Button Bar user control which consists on a Panel control.
Public Class ButtonBar<br />
<br />
Public ReadOnly Property Buttons() As ButtonCollection<br />
Get<br />
Return buttonPanel.Controls<br />
End Get<br />
End Property<br />
<br />
<br />
Private Sub ButtonBar_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
Me.Dock = DockStyle.Bottom<br />
End Sub<br />
<br />
End Class
Into the panel I wish to add a collection of Buttons, therefore I have created a ButtonCollection class which inherits from ControlCollection
Public Class ButtonCollection<br />
Inherits System.Windows.Forms.Control.ControlCollection<br />
<br />
Public Sub New(ByVal Owner As System.Windows.Forms.Control)<br />
MyBase.New(Owner)<br />
End Sub<br />
<br />
Public Shadows ReadOnly Property Count() As Integer<br />
Get<br />
Return MyBase.Count<br />
End Get<br />
End Property<br />
<br />
Public Shadows ReadOnly Property IsReadOnly() As Boolean<br />
Get<br />
Return MyBase.IsReadOnly<br />
End Get<br />
End Property<br />
<br />
Public Shadows ReadOnly Property Item(ByVal Key As String) As Infragistics.Win.Misc.UltraButton<br />
Get<br />
Return CType(MyBase.Item(Key), Infragistics.Win.Misc.UltraButton)<br />
End Get<br />
End Property<br />
<br />
Public Shadows ReadOnly Property Owner() As System.Windows.Forms.Control<br />
Get<br />
Return MyBase.Owner<br />
End Get<br />
End Property<br />
<br />
Public Shadows ReadOnly Property Item(ByVal Index As Integer) As Infragistics.Win.Misc.UltraButton<br />
Get<br />
Return CType(MyBase.Item(Index), Infragistics.Win.Misc.UltraButton)<br />
End Get<br />
End Property<br />
<br />
Public Shadows Sub Add(ByVal Button As Infragistics.Win.Misc.UltraButton)<br />
Dim x As Integer = Item(Count - 1).Location.X + Item(Count - 1).Width + 10<br />
Button.Location = New System.Drawing.Point(x, 8)<br />
MyBase.Add(Button)<br />
End Sub<br />
<br />
Public Shadows Sub AddRange(ByVal Buttons() As Infragistics.Win.Misc.UltraButton)<br />
MyBase.AddRange(Buttons)<br />
End Sub<br />
<br />
Public Shadows Sub Clear()<br />
MyBase.Clear()<br />
End Sub<br />
<br />
Public Shadows Function Contains(ByVal Button As Infragistics.Win.Misc.UltraButton) As Boolean<br />
Return MyBase.Contains(Button)<br />
End Function<br />
<br />
Public Shadows Function Contains(ByVal Key As String) As Boolean<br />
Return MyBase.ContainsKey(Key)<br />
End Function<br />
<br />
Public Shadows Function ContainsKey(ByVal Key As String) As Boolean<br />
Return MyBase.ContainsKey(Key)<br />
End Function<br />
<br />
Public Shadows Sub CopyTo(ByRef Array As System.Array, ByVal Index As Integer)<br />
MyBase.CopyTo(Array, Index)<br />
End Sub<br />
<br />
Public Shadows Function Find(ByVal Key As String, ByVal SearchAllChildren As Boolean) As Infragistics.Win.Misc.UltraButton()<br />
Return MyBase.Find(Key, SearchAllChildren)<br />
End Function<br />
<br />
Public Shadows Function IndexOf(ByVal Button As Infragistics.Win.Misc.UltraButton) As Integer<br />
MyBase.IndexOf(Button)<br />
End Function<br />
<br />
Public Shadows Function IndexOf(ByVal Key As String) As Integer<br />
MyBase.IndexOfKey(Key)<br />
End Function<br />
<br />
Public Shadows Function IndexOfKey(ByVal Key As String) As Integer<br />
MyBase.IndexOfKey(Key)<br />
End Function<br />
<br />
Public Shadows Sub Remove(ByVal Button As Infragistics.Win.Misc.UltraButton)<br />
MyBase.Remove(Button)<br />
End Sub<br />
<br />
Public Shadows Sub Remove(ByVal Index As Integer)<br />
MyBase.RemoveAt(Index)<br />
End Sub<br />
<br />
Public Shadows Sub Remove(ByVal Key As String)<br />
MyBase.RemoveByKey(Key)<br />
End Sub<br />
<br />
Public Shadows Sub RemoveAt(ByVal Index As Integer)<br />
MyBase.RemoveAt(Index)<br />
End Sub<br />
<br />
Public Shadows Sub RemoveByKey(ByVal Key As String)<br />
MyBase.RemoveByKey(Key)<br />
End Sub<br />
<br />
Public Shadows Function ToString() As String<br />
Return MyBase.ToString<br />
End Function<br />
<br />
End Class
My problem is that the property Buttons appears on the properties window in the VB.NET IDE, but :-
a) Does not show any buttons that I have added previously.
b) When a button is added, it is not displayed on the form.
Any pointers on where I should go from here would be greatly appreciated.
Thanks

Is the following C# code the equivalent to the VB code below:
C# code:
if (Page.Header != null)
VB.NET code:
If Not Page.Header Is Nothing Then
Thanks

Yes.

Another alternative, in VB 2005 or higher, is:
If Page.Header IsNot Nothing Then

Hi,
I am sort of new to VB.NET. Using .NET 2.0. In C# I would have static properties in my Globals class. No I am trying to implement the same feature in VB.NET, but it is not working. Here is my declaration in Globals.vb:
Private Const COMPANY_LONG_NAME As String = "My Company"
Public Shared ReadOnly Property CompanyLongName() As String
Get
Return COMPANY_LONG_NAME
End Get
End Property
But then I try to write this name in my .aspx page, but when I try Globals. then CompanyLongName does not show in the list to select from.
Also, the namespace is MyNameSpace, in this namespace the Globals class resides.
Please can someone explain why.
Regards

Sorry the server was giving problems, it kept on telling me that my psot was not added due to heavy workload on IIS.
|
|
|
|
|
is your class in app_data?
|
|
|
|
|
my idea is..
when open the exe form1 will appear onto the screen.
And then when click on form1, i wanna close form1 and form2 will appear.
pls suggest to me...

It the Form_Closed event of Form1 :-
Dim f as form2<br />
f.Show()

won't work. once the scope of the close event is done, the variable is released. you need to put the form2 in it's own message loop.
sub main
application.run(form1)
application.run(form2)
end sub

Do you use the same namespace for the aspx pages? If not, have you imported the namespace? If not, then you have to use MyNameSpace.Globals to access the class.

The easiest way is to connect over the network using SQL Server Management Studio

Look at the SqlDataAdapter and the SqlDataReader.

hi all
when i check the child node of a treeview it will automatically check the parent node of that child node.
can some one tell me how can i do that
i am trying to do that but the recursive procedure (that will check all the child nodes when the parent node is checked) is making it difficult.
thanks in advance
help everyone
|
|

I don't know exactly what you want but here are a few ideas:
when child node is checked and parent noded needs to be checked you can use the parent property of the child node wich will give you its parent node and then you can check that one
when a parent node is checked and all child nodes need to be checked you can use the nodes (I think its called like this but not shure) property of the parent wich will give you a collection of nodes, then iterate thru them and check all of them
hope this helps
If my help was helpfull let me know, if not let me know why.
The only way we learn is by making mistakes.

the problem is
1. when all child and parent nodes are unchecked, then , when child node is checked then i need to also check its parent node. thats exactly what i want to do.
what i have done
1. when a parent node is checked, all of its child nodes is checked.
2. when a parent node is unchecked, all of its child nodes is unchecked.
3. checks and unchecks all the parent nodes and child nodes with the help of buttons.
all these things are using some sort of recursive function and thats cause the problem. i use all that in aftercheck event of treeview
any help will be thankfull
help everyone
