So im creating a mail bomber here is the code
Imports System.Net.Mail
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
[CODE]...
Pretty simble but im trying to make buttons that chage between [URL] and [URL]on the timer code
Dim MyMailMessage As New MailMessage()
MyMailMessage.From = New MailAddress(TextBox1.Text)
MyMailMessage.To.Add(TextBox3.Text)
[CODE]...
My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:
If datareader("Who_Second").ToString = lbl_Your_Position.Text Then
Dim b1 As New ImageButton
b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString
[code]....
What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:
Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
Dim MyDate As Date
Dim QCC_Q_ID, Position As String
[code]....
Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?

How can I make buttons on a form to respond to keypress, keyup and keydown event?
View 3 RepliesUsing VB 2008 Express.
Attaching code to buttons when they're clicked is easy when they're static buttons on the form; just double click the button on the form designer and add code to the event.
I have a series of buttons that are generated in a control array, so they're generated in a class, and in the form there are no buttons until runtime.
So newbie question with a probably simple answer...how do I enter code for the click event for buttons that aren't there until they're instantiated as a class at runtime?
I have a quoting system that can generate several variants of a quote. these quotes are displayed on a screen for sales staff to compare and choose which is the most suitable. Is it possible to programmatically create a button and click event for each quote that is generated?
View 1 Repliesi have created a list of buttons using the following
Dim Butt(20) As Button
Dim i As Integer = 0
While (i <= 20)
Butt(i) = New Button
Me.Controls.Add(Butt(i))
i = i + 1
End While
this means that buttons are created in the code and not on the form to begin with, so I don't know how to create an event for the click of a button in a list. Is it possible to do it with a parameter for i so that there is only 1event for all buttons in the list, and i is the button index array clicked?

View 1 RepliesI am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?

View 5 RepliesI have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
