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 RepliesIam wanting touse sendinput in a dos or background type app (can be a regular app thats hidden) that emulates mouse clicks and sends mouse moves to another multimouse application. an project that im working on for my school i work at and i need to send the input to it. The overview of the project is i need to have this code be in a service that runs in the background that when a person does a gesture with my kinect code then it clicks the left mouse or sythesis it with sendinput (need mouse up and down sent for this to work). The end programs that receive input are: a program written in the multipoint sdk and mouse mischief. I though about using the default usb mouse driver as an emulated mouse driver to handle the part about creating a usb mouse device that works
since most newer computers are using usb.
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 RepliesI have a form on a program i am working on that i need to check if all the textboxes hold a separate value when a button is clicked. I know that i can use comparative operators to check the values are different, but i am using 6 different textboxes, and don't fancy typing. [Code] 36 times over, could somebody point me in the right direction for an easy way of checking that 6 textboxes hold different values. Also, as a sidenote, i would like to know if there is a way to check if all 6 are numeric in an easier way than typing is-numeric(textbox1).

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 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?
I am adding a series of RadioButtons to a GroupBox programatically. By default they are all placed on top of each other. So I use a bit of math to position them all nicely and then resize the GroupBox.
However I notice that the GroupBox has an AutoSize property, but it doesn't seem to be resizing as controls are added.
Is there a better way to position my radio buttons than to specify each one programatically? I mean, can't this stuff be handled automatically by the framework?

want to make a custom calendar. For that I made a table of 7 cols and 6 rows and added 42 buttons in it. I added an event handler. I used this file in other form and when I click at the button the event is fired in form2. I understand this is not hte efficient way to add so many buttons. As it is a calendar, so I got to add dates to buttons based on month selected.I am finding that part difficult. For this feature, I think I should add buttons dynamically. But I can't make out how to add buttons to each cell of the table. Later on each buttons text will also change. I have added the code written so far :
Public Partial Class CalendarControl

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 4 RepliesI have to create buttons at rum time based on database records and implement their events.
View 5 RepliesI want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.:
1: A C E
2: D E
3: B A D
result: B A C D E
above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A.If there are conflicting orderings, the first ordering should be used. i.e.
1: A C E
2: B D E
3: F D B
result: A C F B D E 3 conflicts with 2 (B D vs D B), therefore requirements for 2 will be used.
If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained.
This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.
Edit: Edited to make example 2 make sense (a last minute change had made it invalid)
I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

How would i go about detecting While the user is moving the mouse and also holding down the left mouse button. like they were drawing something with a pencil in paint.
View 16 RepliesI took a VB class a couple semesters ago and I did really well. Unfortunately, it seems as though we only covered the very basics within the class, as I feel rather clueless right now.
Here's my issue. I'm trying to write a program that will encode notes (like music notes, A-G#) which are entered by the user, into digits, 0-9. Now I have the system laid out, in that 1-8 will represent A-A, while a 0 or 9 preceding a digit will represent a flat or sharp respectively.
Now my question is actually rather basic, but I just can't seem to figure out how to do this. The user will enter the note sequence by clicking on buttons (12 of them). What I'd like to do is create one sub that will handle all possible button clicks. I suppose it's possible that I could have separate subs for each and every button; but it just seems more efficient and cleaner to have one sub that manages them all.
The part I have completed and working properly will display a message (the same message) in a messagebox each time any of the buttons are clicked. So I have the "Handles" part working for all 12 buttons. But what I'd like to do is write code, perhaps "If" statements such that If "btnA" is clicked, then say "You clicked Button A," and If "btnASharp" is clicked, then "You clicked Button A Sharp," and so on. Is it possible to do this somehow by recognizing which event was actually triggered?
