.net - Converting A CollectionChanged Event Handler Line From C#?

Oct 27, 2011

I've used the developerfusion C# to VB conversion tool to convert Brad Smith's ComboTreeBox project and I'm having troubles on, as is fairly normal for me and C#-to-VB conversions, an event handler.

In the interface implementation for IList(Of ComboTreeNode).Item there is this C# code:

#region IList<ComboTreeNode> Members
public ComboTreeNode this[int index] {
get {

[Code]....

I'm getting errors on the last two lines of the Set method and frankly I don't understand what's even being done, there. It appears, from my limited C# events knowledge, to be adding an event handler back onto the event itself, which leaves me completely lost.

Doing a naive conversion to AddHandler value.Nodes.CollectionChanged, AddressOf CollectionChanged just brings up a reminder that the second argument of AddHandler needs to be a method address.

How To Convert C# .NEt Custom Event

Mar 6, 2011

I am trying to develop a VB .NET Windows Form Application FTP client that uses the C# .NET FTPLibrary.dll that I obtained from The Code Project article "A Windows FTP Client". I am also converting and using significant amount of the code from the article which, for the most part, I have been able to successfully convert to VB .NET using Developer Fusion's C# to VB code converter. The dll has a new message handler (NewMessageHandler) which is used in the article's main form (frmMain). There is a C# .NET statement in the SetFtpClient() method of frmMain that I am unable to convert to VB .NET. I have boxed the statement I need help with converting to VB .NET with " ===== " statements. [code]

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

Jul 31, 2010

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

Heres the tutorial with my new code encased in asterisks ...

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?

Jul 20, 2010

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).

I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

[Timer] Trigger Event Manually - User Must Wait For A Minute Before The Event Is Triggered

Feb 12, 2010

Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True

[CODE]...

Is it possible to force this event to occur instead of waiting for it?

Make Sure 'ProgressChanged' Event Executes Completely Before Executing 'RunWorkerCompleted' Event Of Background Worker

Sep 20, 2010

Starting from my understanding about Background worker control, I understands that the background worker runs the code in its "DoWork" method in a seperate thread, while ProgressChanged and RunWorkerCompleted events are executed on the main thread.In my senerio, I report the progress and under an specail condition my application displays a message box to the user in "ProgressChanged" method using MessageBox.Show(). and in "Run Worker Completed" event the application finalize some work. There the sequence is important, suppose that the message is of Yes or No type and finalization depends on it. Now when i run my application, the background worker triggers "ProgressChanged", but as soon as backgroundWorker's cancelAsync() is called the program leaves the current "ProgressChanged" method and executes "RunWorkerCompleted" code first.How can i make sure that the "Run Worker Completed" code executes only after the completion of ProgressChanged method.

Event Argument For The Form Click Event Has The Type "TimedEventArgument"?

Dec 23, 2009

As you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

Get Information About A Processes When An System Process Event Is Raised An Event

May 17, 2012

I am making a function of an application that when a function is called the application will close all processes that are owned by the user and were started after a specific point. My thoughts on this would be to trigger an event in my application every time a process is started and ended, and only if the processes is owned by the user, the event should get information (e.g. the process ID, name, etc) about that process and add or remove that information to/from an array depending on if the process starts or ends. Then when a function is called end all the processes in that array.

LEAVE Event And LOST FOCUS Event When Entering Data

Feb 9, 2011

I have a Visual Basic Program that, when I enter data into a textbox, uses LEAVE events to update it. However, it will not update until I go to another textbox or press a button or other similar control.This also happens when using the LOST FOCUS event.How can I make the textbox update (be it doing a financial recalculation or some other custom function) happen when the user clicks/tabs out of the textbox and NOT having to click on a button or into another textbox?Do you recommend having a separate button for performing the custom functions?

ADO .NET Equivalent Event To MS ACCESS Form's OnCurrent Event

May 11, 2009

I just want to know if there any equivalent event (ADO. NET VS 2008) event as in MS ACCESS Form's OnCurrent Event.

The reason is I like to make some calculations based on some data bound controls with current datarow data when user clicked a row in DataGridView (or by using bindingNavigator). I've tried with DatagridView's RowEnter event. But some Data bound controls are not yet reflect the data of current datarow when that evet was fired.

In MSDN Help File: It says "RowEnter Event: Occurs when a row receives input focus but before it becomes the current row. "
