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

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?
I am getting an error when I code a Sub for btnDelete_Click...and it's coming from my FormActionHandler. Here is the code in my FormActionHandler:
Public Shared Function DeleteVendor(ByVal oldVendor As Vendor, ByVal newVendor As Vendor) As Boolean
Dim aServiceFactory As PayableAppServiceFactory = PayableAppServiceFactory.GetInstance()
Dim aVendorService As VendorService = aServiceFactory.GetServiceInstance(PayableAppServiceFactory.SERVICE_NAME.Vendor)
Return aVendorService.DeleteVendor(oldVendor, newVendor)
End Function

View 1 RepliesI'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 ...

i made a program and used a program called Advanced Installer to put all the files from the build folder into one big install exe file to send to people but one they've installed it and go to open it they get an error saying: "the application has failed to initialize properly (0xc000135). Click on OK to terminate the application" What does this mean? do i need to have the NET framework on the machine its being run on?
View 6 RepliesI 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

Ok button click is not accessing click event.
I've been going round and round with this and thought maybe someone would know.I've created a program which with process.showdialog calls up a form into which the user enters username and password then is given access to the program itself. If the username and password is incorrect, the program closes.
There is a frmMain and in the form load I've added the process to open this sort of splash login screen. It's not a splash really, it isn't timed to close down.
I fill out the login information, click the save settings checkbox which creates a settings file in MyDocuments. My problem is that in debugging, removing the click closes the login page without the click actually becoming unclicked. The Main program opens before there's been a chance to register the "unclick." Hope this makes sense.

View 2 RepliesI 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.
View 2 RepliesI 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.

View 2 RepliesI'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1? [code]
View 7 RepliesAs 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?
