Get A Substring Of A Datgridview Cell?
Aug 15, 2011My application is in VS2008 coded in Vb.net. I have a datagridView which is getting populated from the Database.I has RegNo,RollNo,Name etc fields.The data in the Name column of database is coming from 3 columns of a certain table from database. This is how im concatinating it and displaying in datagrid.

My issue is i want to save this data in some other table which also has Surname,FirstName,LastName columns in the database.

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event
Jul 31, 2010I'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?

View 2 RepliesOverride An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?
Jul 20, 2010I'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, 2010Eg. ""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?

View 7 RepliesMake Sure 'ProgressChanged' Event Executes Completely Before Executing 'RunWorkerCompleted' Event Of Background Worker
Sep 20, 2010Starting 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.

Dec 23, 2009As 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, 2012I 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, 2011I 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, 2009I 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. "
ALERT: Event Handling - Capture The Event For When The F1 Key Is Pressed
Feb 15, 2011I have alot of experience in working in VBA for excel, but not so much experience in creating my own structures so it's all still a bit foggy. I'm trying to capture the event for when the F1 key is pressed, not just when the form is active, but anytime the program is running. The code below expressing the handling is automatically generated for me in VB Express... But I'd like to change the situation to encompass anytime the program is open. I guess I have to reference events that happen in windows in general, but i don't know how to do it. I think i have to create the even in a class module?
