Make Application Respond To ANY Click Event?
Apr 17, 2010
I have a very simple application where I have 16 pictureboxes which are created at run time. I would like the user to click one and for me to know which one is clicked.
Unfortunately, I have no idea how to go about doing this in VB.NET. I am only just getting into the whole object orientated thing and this is something which is causing me to get stuck.
The code I am using in my picturebox array class is below as I thought it would be easier than me trying to explain what I am trying to do with it.
Public Class PictureArray
Inherits System.Collections.CollectionBase
Private ReadOnly HostForm As System.Windows.Forms.Form
[Code]....

I have a class, BaseSample, that uses another class, MainData, as one of its fields:
Protected _sampleData As MainData
Public Property SampleData() As MainData
Get
[code]....
MainData in turn has a collection of a class, ProcessData, as a field and ProcessData has a collection of a class, Measurement, as a field. I.e.:
MainData
|- IEnumerable (Of ProcessData)
|- IEnumerable (Of Measurement)
These classes are entities in a LINQ to SQL file. In the Measurement class, I raise the PropertyChanged event when the CrucibleOxidizedMass property changes:
Private Sub OnCrucibleOxidizedMassChanged()
RaiseEvent PropertyChanged(Me, New ComponentModel.PropertyChangedEventArgs("CrucibleOxidizedMass"))
End Sub
In the BaseSample class, I want to respond to the CrucibleOxidizedMass PropertyChanged event in any of the descendent Measurment instances. How would I do this?

I have a datagridview which is populated from a database. I have added buttons to this to edit, view, delete. For some reason using the edit button and updating the database my grid fails to respond. I have it set up to display an image based on the row I click on. Before the update this works, after is does not. After the update I run a reload() where I clear out the dataset and repopulate the datagridview. Here is the code I am using for the reload and the update.
Public Sub reloadDG()
'reloadDG is used to clean out the information currently in the datagridview and is replaced with
'current data
'calls refreshForm()

I have some code in a label's mousemove event that allows it to be dragged around my form while the left button is held down. While this is happening none of the other controls on the form respond to their own mousemove events as the mouse pointer passes over them. Is it possible to make more than one control respond to mousemove events at the same time?

How do we make a visual basic listbox to respond directly when the user clicks on the items in the textbox? (such as making a menu appear or displaying info in a label when the items are clicked)
I have used the SelectedIndexChange event but nothing happens when the listbox items are clicked. The SelectedIndexChange event only seems to work when a button is added. It seems that the button's click event gets the listbox's selectedindex change event to start working. The listbox's textchanged event doesnt seem to work also.
Is there any way to make the listbox respond directly to the user's clicks without the use of button controls?

I'd rather not go into the detail of the problem, because it's a lot of typing... but the functionality of vb.net (when making a web application) is quite annoying.
This is what it does...Page1.aspx loads, then you push a button on the page, and that button then does this: Response.redirect("Page2.aspx")
But first, it does Page1's load event, then it does the btn.Click event, THEN it does Page2.aspx's load event... Is there a way to force it to not do Page1's load event, and just make it execute the button click, and the page2's load event?

First, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then
BlockInput(True)'this disables the mouse and keyboard
Dim IE As New Object
[code].....
There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work. Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas? I'm trying to mimic Windows calc.exe for a school project and thought I'd try throwing in a few extras such as numeric keypad functionality.

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 ...
Code:
Imports System
Imports System.Windows.Forms

I'm trying to make an application which has a feature of an event calendar. I am quite familiar with the MonthCalendar tool in the toolbox, but that's not really what I'm looking for. I would like to make a calendar that somewhat resembles 'iCal' in Mac OS X. If any of you use Microsoft Groove Workspaces, the calendar in that is very close to what I'm thinking of. I want the user to be able to double click the day and add new events which will show the title of the events in that day on the calendar when the events are saved. Also i would like to have the user be able to make recurring events. Is this even possible with Visual Basic '08?

I have 4 items in a ListBox and each item does a specific thing when it gets clicked on.But I also want the double click event to do the same thing as the click event.I can copy and paste all code from click event into double click event, but then you have lots of code crowding the code page doing the same thing. So what to do about this?
Example:
Private Sub listBox1_DoubleClick(ByVal sender As Object, ByVal e As EventArgs) _
Handles listBox1.DoubleClick

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

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

Can i Know how to catch between these 2 event, Leave and Click?
I have one checking in a textbox Leave event. I will go check whether this ID is already exist in DB or not. If exist, I will prompt MSG box to user.
When I click on Close button while focus is on textbox, this textbox Leave Event will trigger first before Button Click event.
So, the form remains open without trigger Button Click event.
how to prevent this textbox leave event or how can i catch/control this situation?
