I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.

I have a modified button control with a string array in it. I am having trouble sending the string array to the form with the modified button on it. Anyone know what i can do? The form uses a arrayList to hold the buttons since they are made at runtime.

I have created a custom control that has a few labels and a button on it. In my main program i dyanmically add this control to a stackpanel. When i add the control i add a few events for it by doing th e following:
Dim newqueue As New UserControl1
AddHandler newqueue.MouseDoubleClick, AddressOf PrintMessage
How would i go about adding an event for the button.click for the button in the custom control?
I would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.

View 4 RepliesI have the following problem:
I've got 3 lines
If I click the "next" button
Line 1 shall be highlighted
Then I I click ""next" again
[Code].....
a for i = 1 to 3 to loop within the Button1_click makes i directly 3 of course so line 1 and 2 will not be highlighted.
I am not allowed to use a msgbox in between cause then it would be easy, cause I would wait until "OK" would be pressed...
How can I make this for i = 1 to 3 loop work and highlight the lines 1, 2 and 3, one by one after pressing the "Next" button?
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.

View 1 RepliesI want to do a For Each loop where i can check whether each button is enabled or disabled. If the button is enabled then i have to obtain the values in the tags for each button. I have 26 buttons each containing different values (cash prizes).*IMPORTANT: this code needs to go under the button so every sixth time its pressed it checks the buttons.
Pseudo-Code:
btncase1.tag = 5
Begin while statement to go through each button
Check each button to see if it is enabled

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?
View 9 RepliesI'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.
Attached you can find the main screen:

I am using VB 2010 , I have a loop that takes something like 5 minutes until it's finish. I want to allow the user the option to stop it in the middle or whenever they want. There's a button which starts the loop, and after I click it the loop starts running and the button is sort of "stuck".I saw something called "background work" in the VB Toolbox, can it be a solution to my problem?

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.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On
