C# - Way To Implement Caliburn-like Co-routines In Since There's No Yield Keyword?

Mar 26, 2010

Note that I'm aware of other yield in vb.net questions here on SO. I'm playing around with Caliburn lately. Bunch of great stuff there, including co-routines implementation.

Most of the work I'm doing is C# based, but now I'm also creating an architecture guideline for a VB.NET only shop, based on Rob's small MVVM framework.Everything looks very well except using co-routines from VB. Since VB 10 is used, we can try something like Bill McCarthy's suggestion:

[Code]...

It definitely isn't as elegant as C# version, but it looks to be doable. We'll see if there are any problems with this. If anyone has better idea, I'm all ears.

VS 2008 Use The New Keyword To Create Object Instance

Apr 13, 2010

VB is telling me to use the "NEW" keyword to create an object instance. For example: Private Sub ScoreTotal(ByVal sender..., ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

[Code]....

When I run the "MainStudentScores" form and click on a student with three scores separated by the "|", it should give me a Score Total, Score Count, and Average. However it is giving me an error message at "Scores.Add(intPlaceHolder)" This is where VB is telling me to use the "NEW" keyword. Does this make sense?

VS 2008 How To Implement The IBindingListView

Oct 19, 2011

I have a custom object that I would like to turn into a Collection that could then be used in a BindingSource. From what I've read, I can Inherit Collection(Of T) where T is my specific object. Then I can Implement IBindingListView. This is all great, but I have no idea how to actually use the IBindingListView Interface. I know I want to be able to sort and filter my collection, so I have the following.

Imports System.ComponentModel
Public Class ChemicalCollection
Inherits Collections.ObjectModel.Collection(Of Chemical)

[code]....

As you can see, I haven't really done anything other than let Visual Studio fill in the required properties and methods when I implemented the interface.

VS 2008 - How To Implement New Encryption Algorithms

May 28, 2009

I want to try and use the new encryption algorithms provided with .NET 3.5. Any links or examples for how to use one of them to encrypt xml content?

As written on msdn site is:
The following algorithms are included:
Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits for encryption.
Secure Hash Algorithm (SHA-256 and SHA-384) for hashing.

Elliptic Curve Digital Signature Algorithm (ECDSA) using curves of 256-bit and 384-bit prime moduli for signing. This algorithm is provided by the ECDsaCng class. It allows you to sign with a private key and verify with a public key.

Elliptic Curve Diffie-Hellman (ECDH) using curves of 256 and 384-bit prime moduli for key exchange/secret agreement. This algorithm is provided by the ECDiffieHellmanCng class.

VS 2008 : Infinite Undo/redo: How To Implement It

Apr 4, 2011

basically add and remove text and selection information from a stack. Result: When using Undo/Redo the selection got messed up, the text moved, sometimes causing lag of epic proportions. I need a way of having complete and smooth undo/redo class for storing all information I would possible need.How to know whether or not to add an undo stack is easy, I just checked if the user clicked in the text or moved using the arrow keys. As soon a previous marking was given for "next text change needs to be backed up", it was backed up. At that point I stored the RTF and selection start/length. What do I have to store of a RichTextbox control to be able to restore it to a previous state, and how can I reset it back to a previous state? See it as having a "RichTextBoxState" class:

Public Class RichTextBoxState
Sub New(ByVal RTB As RichTextBox)
Me.text = RTB.RTF
Me.selectionstart = RTB.SelectionStart

[code]....

After restoring it must display the EXACT same thing as when it was saved as a state.

VS 2008 - Implement Event To Detect User Inactivity

Jul 30, 2011

PROJECT TYPE: Windows Forms Application
LANGUAGE: Visual Basic
.NET VERSION: 3.5
IDE: Visual Studio 2008
OPTION STRICT: on
OPTION EXPLICIT: ON

I am developing a parental control application containing a feature that logs a user off of the computer after an administratively set period of time. I do not however want the application to continue counting time against the time limit when the user is not active on the computer. EXAMPLE: Child logs on and is active for an hour then leaves computer for 45 minutes to get dinner. The session timer needs to ignore the 45 minutes of inactivity. I have thought of two ways to accomplish this.
1) Use a SystemEvents.SessionSwith event (to detect the Start Menu > Log Off > SwitchUser action), or
2) Use an event which would detect user inactivity in excess of a set time, e.g. 5 minutes (similar to a screensaver).

Either event would call a method which would simulate a pause feature (as StopWatch and Timer have no pause support that I know of). I believe the 2nd option would prove to be more universally affective as 1) some users do not have Fast User Switching enabled, and 2) users would be required to manually switch users in order to prevent their inactive time from counting against them. My problem arises when I attempt to implement one of these methods. According to the IntelliSense error checking engine, I have absolutely no clue how to do either of these tasks in spite of the research I have conducted on the topic. I would prefer to go with the system idle time approach.

2003 Upgrading To 2008, Implement The New Data Features In An Application?

Dec 17, 2008

I am upgrading from Visual Studio 2003 to Visual Studio 2008. ow I should upgrade my project.My project is in Visual Basic.Net, and using an Access 2003 Database. I have four datasets, MainDataSet (for the main data tables) LookupDataSet (for lookup tables States, Countries, Colors, etc) OneFormDataSet (data used on only one form) and ReportsDataSet (data used for reports).I have one form "OleDbAdpatForm.vb", that has all the OleDbDataAdpaters for my project. It also has the DataSets and the OleDbConnection.I have public functions that enable me to load the data tables.

I have a LoadTable function when I can pass a column and a value, and the SQL select command is updated with a WHERE or HAVING, so only the requested data is selected. I also can pass the whole "WHERE ..." part of the SQL select command, so I can have multiple parameters in the SELECT command.On my other forms, I have copies of the DataSets, so I can design grids/controls. In the form_Load events, I manually bind the controls to DataSets and tables in located "OleDbAdpatForm.vb", so all forms are using the same data tables, and changes made to data in one form are reflected in data in other forms.The VS 2008's DataSources, BindingSources and TableAdapters seem much easier to use. how I should implement the new data features in my application?

For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then

.net - Does C# Have A Handles Keyword

May 25, 2011

Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
End Sub

In VB.net, we have the Handles keyword, I'm wondering if C# has anything comparable. Or do you have to manually wire all the methods to each control's event (in ASP.NET especially)?

Extended With-keyword In .NET?

Oct 29, 2010

In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.

veryLongVariableName.Id = datasetVeryLongVariableName.Id
veryLongVariablename.Something = datasetVeryLongVariableName.Something
etc.

Using VB.NET's With keyword can help.

With veryLongVariableName
.Id = datasetVeryLongVariableName.Id
.Something = datasetVeryLongVariableName.Something
End With

Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:

With veryLongVariableName As a, datasetVeryLongVariableName as b
a.Id = b.Id
a.Something = b.Something
End With

I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!
