Get A Do While Loop To Repeat With Each Button Click
Oct 17, 2009
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. The program needs to update each time I use my btnCalculate button by adding one student and updating the avg.MY question is how to I get my do/while loop to work each time by just hitting my calc button? [code]
I have a simple program that takes the number of students and calc's the avg. It is suppose to add one student,(female, male,all) with each button click and update the avg. I have a loop set up to do this but I don't know how to get my do/while to work once, each time I press my calc button or can't it be done this way?
I'll try to past my code so far:Public Class frmMain
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?
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 am waiting for a confirmation email to arrive within the web browser I am using I do not need to click any buttons to open this mail I just need some help figuring out how I can check whether it has arrived or not I already have the code to find the link and navigate to it (I had to navigate rather then invoke due to it trying to open in a new window outside of web browser and out of my control)
How can I keep checking for my specified element and when found carry out the rest of my code or is there another way I should be doing this the code I am using to find the verification link and navigate to it is as follows

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.
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.
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]
