View 3 RepliesI 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.
how I can implement my calendar with VB .net express 2008 and MSSQL 2008 Express. How do I get it to work with datasets, binding source etc.If I go to Properties>settings my connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|CalendarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
and I have a table with fields:-
CalendarID
Subject
Location
Purpose
[code]....
I can Add the event to the calendar I have the necessary items on my form linked to my table and I can save them to my table:
Me.Validate()
Me.CalendarTableBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.CalendarDatabaseDataSet)
But I cant keep the event displayed on my calendar when I close it and open it again.

View 22 RepliesI 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.
I am making an application that has a tabbed interface. Each tab uses a UserControl with the controls that I need on it. The user enters some data & clicks a button, which starts a lengthy process. I would like to run that process in a BGW, so that the user can switch to (or open) another tab & process another set of data simultaneously.

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.

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.
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?

I have a Richtextbox and I would Like the user of the program to be able to drag and drog the richtextbox in other specified places in the program.
I have this very basic
Private blnLifting As Boolean = False
Private Sub richTextBox4_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox4.MouseDown
[Code]....
Firstly its very inaccurate. I want it so the Richtextbox moves with the mouse and not after the mouse. So I want a smooth drag and drog.
So I don't know if this is the wrong code for something that I want perfect like that.
Secondly I dont know if its possible but I would like it so the box can only be dropped in certain area's in my program and if there is a box already occupying that space, It goes back to where it was before.

I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code:
''' <summary>
''' Exports data from a datatable to excel.
''' </summary>

Where in Visual Basic 2008 Express Edition Software program do you specify a specific installation directory for a program?
c:Program Filesfinished program
I want to publish my program to try it out on another system and I want to ensure its installed in the directory structure I want.
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
