i`m trying to use a progress bar while i click a button to start my web cam. It needs about 2-3 seconds to display the web cam capture image in my picture box. When i use the following code the progress bar starts only when the capture image is displayed in my picture box, it waits those seconds to start. What can i do about that problem?

View 4 RepliesI am looking for a method to dynamically execute blocks of code ('tasks') in a VB.Net program for a mobile robot. The bulk of the program is running in the background retrieving variables from serial ports, APIs, and the like. The user would select a task in the form of a toolbox button which pops up a dialog to enter task parameters. An accept button would add the task with the parameters to a list. The user would add more tasks to the list as necessary, and then click an 'Execute' button to start the sequence of tasks. The program would then perform the first task with the given parameters until finished, and then start the next task in the sequence and so on.
An example task would be:
GPS Navigate:
A Parameter dialog opens and a destination is entered in the form of GPS coordinates. At run-time the task compares its current GPS position with the position entered in the parameter dialog. It calculates the direction to go and drives the motors accordingly. This particular task would loop until current position = destination position. Move on to next task. The code within the tasks themselves is not the problem, just the execution of the tasks.
I am back - I have my code - it is part of another main form for a child's desktop view. I have it in a console app that works great. My new form has 3 text boxes, and a start button - txtquestions, txtUserAnswer, txtResults and cmdStart - to start the game. I made some slight changes in the numbers, because I needed it for a younger child (6-7), and removed 1 case in the case select (a square root problem too much for a little one). I click on Start button, and it freezes up. I am in Debug, but do not get any kind of problems showing me a bad line of code.
Here is my code:
Public Shared Function Parse(ByVal txtUserAnswer As String, ByVal provider As IFormatProvider) As Integer
End Function
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
Dim endprog As String = "YES" 'define the answer for not ending the game
[CODE]......................
I am not sure about the loops, but it doesn't just freeze up anymore, as in an endless loop. Now I am getting a stop at the first 'parse'. I actually followed the instructions in a VB 2008 book to do this, and in the help section of Visual Studio with the function and the parsing. But, that is where it stops - I know I had to convert the input into - at least I think I did. The text box for input is just that input. The user's answer is typically a number, except for at the end.
I want to include a functionality in my application such that when the user clicks on a button, the user should be able to record the voice, and when stopped, the sound should be saved. Here's what I wrote for the Start and Stop button.

I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?

Form 1:

If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?
We only have few meetings for Computer subject that's why time did not permit us to discuss timer codes. Anyway, my concern (I think) is just simple (though I really do not know how to start).I plan to make a countdown timer of 60 s that will start once "Start" button is clicked and will display a message box when it reaches 0. I only know the codes for message boxes.
