View 4 RepliesClick Execute Button To Start Sequence Of Tasks
May 12, 2009I 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.
Converting VB6 Code - Click On Start Button, It Freezes Up ?
Apr 25, 2009I 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.

View 7 Replies.net - Why Cancelling 6 WebRequest Using Task.Start Takes Longer That Thread.Start
Jul 24, 2011I have custom asynchronous WebRequest class that I am testing to find out how fast the request will be cancelled and found some odd results, that starting 6 WebRequests with TPL and cancelling them right away takes 25 sec, but when I used just regular background threads it took only 5 sec.
Update: Running them without cancelling takes with Task.Start 9 sec and Thread.Start 3 sec accordingly.

Operation:The new thread is set equal to an existing thread, then the existing thread is started and aborted. How does one restore the old handle count? Why do the handles increase by a random number and do not revert?

I only know the codes for message boxes.
