I am writing a simulator program that gets its I/O from external sources with results displayed on a form. I heve composed a form, with graphics that look great, but when I call a loop to actually start the simulation, all my labels on the form go transparent and the 'stop' button I have created does not function.I have tried placing this continuous loop in the form code box and in a separate module but to no avail. Even just putting a clock on the form does not work - it prints to screen initially, but only refreshes when I run the cursor over the stop button.This leads me to believe (remember I am a VB novice)that a form is full of Subs that only run once on form load.So where is the main body of code placed that will run continuously; from where I can check the button status and update the form?
I have a simple project that calculates the grade avg of male, female, and both using a listbox and radio buttoms for male and female.

[code]
How would a person stop a try loop once it has started a button click on the same "Form1'? Let's say in this example p = 100. If I wanted to stop it using a button how would I, I have searched Internet and found nothing that is working.
In my application, I want to have 10 webbrowsers, which go to google like this. For i = 0 To 9 Dim Browser As New WebBrowser Browser.Name = "Browser" & [i] Browser.Navigate("[URL]") Browser.Visible = True Next
So now I will have 10 webbrowsers aimed for google, right? So how do I make a loop that clicks the search button 10 times? I know I need to use member_invoke like this Browser.Document.GetElementById("search").InvokeMember("click") But I have no clue how to code the loop.
So basically i need to make a loop that only lets the user click it ten times then gives the answer to them.i was gonna use a DO loop that looks like this so far.
Dim counter as integer counter = 0 Do until counter = 10 loop
and after that i'm kinda lost on what to do, i know that its needs to be if you click btnenter 10 times give the right answer and then your done.

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.
How can I make a program so you click a button and select a File using a OpenFileDialog and click send on your computer and it will send the file to a different computer and then a SaveFileDialog will show asking where to save the file on the other computer. Oh ya I cant use WinSock or whatever becuase im using Windows Vista 64 Bit. I need it because I for some reason cant use printer sharing. It might be because im on A 64bit Vista Machine and I want to print a file off of a 32bit XP Home Machine.
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.
I'm trying to detect if the Sub New() in my class has ended early due to missing fields. Below is a sample of my code:
Class Account
Public Sub New(ByVal Firstname As String, ByVal LastName As String, ByVal Username As String, ByVal Email As String, ByVal Password As String) ' Check For Blank Fields[code]...
How would I catch the Exit Sub from the class in the parent form to prevent the further processing of Process.OtherUse()?
1. Retrieving data from an .mdb 2. Displaying the table(s) in a datagridview 3. Populating an array of structures with the table data 4. Searching the array of structures for a member value equal to a string 5. Displaying the matching array elements in a listbox.
[code] Any suggestions? Am I missing something simple? Should I be using a Multidimensional array instead of a structure?
I have a basic window that has 20 buttons (One, Two,.....,Twenty).Currently if you click on a button its background color changes, and changes back on next click.I'm looking for a way to make it so when the mouse button is held down I can drag across the screen and it will change every button I hit.Disregard the "Shut Down", "Restart", "LogOff", "Clear", and "Invert" buttons. This idea doesn't apply to them.
I have made a program that loads all the songs on my computer into a listview and plays them at random (at least that is what I want) right now I have them moveing to another list and removeing them from the current list so that none are played twice but I can't figure out where to put the code to make it wait until one song stops before starting the next song. is there a media completed function or something that I'm missing?
I have the following code in a VB .NET application. I am trying to update columns in an Oracle table with data with SQL data. When I run the application, I get (ORA-00933: SQL command not properly ended) for the 'or_cmd_3.ExecuteNonQuery()' line.
If I strip out the code and run it in TOAD or SQL Developer, replacing the temp varialve with some bogus data it updates fine. What am I missing?
ElseIf (oracle_summary_temp = ueio_tmpALM_Summary) And (oracle_request_ID_temp = ueio_tmpALM_ID) And added_to_alm = "1" AndAlso ({"Deferred", "Rejected", "Closed"}.Contains(ueio_tmpALM_Status)) Then Dim update_oracle As String = Nothing
I'd like to detect a textbox change but only take an action after it is completed.
The problem is the number which is four digits is changes one number at a time so a normal text changed event will be forever logging a change. Ideally it would detect the change and only display a popup 5 seconds after the change is completed (ie no further changes detected!)
One the click of a button the stopwatch starts, then on the click of a second button the stopwatch stops then states either in a msgbox the time taken between the two button clicks.
We are having problems with the speed in parts of our application, Standard .NET 4 Windows forms application. We have a ListView containing some commerce items and the user can click on items to put them in a shopping cart. The problem is that when clicking 10 times fast on one item, only 4-6 items is added to the shopping cart.I get the same result when building a simple test application with only one ListView, with one item and a debug.print in the click handler.I have tried to add a Button in the same testapplication and this is fast..[code]
i just started playing with the menu toolbars in the toolbox. neat stuff. this thread is mostly for a contextmenustrip, since i'm trying to do a virtual right click on a regular click so the context menu shows..
i would like to know how to do a virtual right mouse click, so that's primary and reason for this thread, but if there is another way to have the context menu act on any other commands, then do post..
