I would like to get my program to run in the background. The EXE file I have created, I want it to run in the background and yet do not want to show the user that the program is running. Like I don't want to have the minimized screen on the task bar. Can I do it in my VB.net program.

View 1 RepliesWhat's the easiest way to run a periodic task in the background in VB?
For example: Update a label every second with the current time, while still allowing the form to be available.
i want my program to understand what i push the key "+" for example and do something. i can write this "something" but i dont remember how to make it see when i push the keyboard keys (NOTICE: i want the program to see the keyboard keys even if the program is minimized and another program is maximized)

View 2 Repliesi have a win form, where i have a block of code which keeps checking for entry in database, every say 2mins, now i want to avoid using timer control, for performance reason, can the same be achieved using background worker.
View 1 RepliesI have been pulling my hair out trying to get this to work. If I step through the code in debugger it all works great. My problem is if I just run it, only the last task responds. I'm guessing I am overwriting the background working or something. I am sure I am doing a few things wrong but my code is now messy as I tried many way while searching. I know of the threadpool and .Net 4.0 tasks but having a hard time getting to do what I need.
Basicly I am writing a program (trying more likely) that takes a list of computers and pings then, then checks their uptime and reports back.This works fine in the UI thread (Obviously that locks up my screen). I can have the background worker just do this, but then it does each computer 1 by one, and while the screen is responsive it still takes a long time.
So my answer was to have a for loop for each server launching a new background worker thread. My solution does not work.I have seen other threads that I could do it, but I need to use with events to call code to update to UI when each is done.
What is the most simple way to do this?
Here is my code. Most is just copy paste + modify till I get it working right.
So In the main class I have the testworker.
(I tried using Testworker() but it said I could not do that WithEvents)
When I click the button the list loads.
Private WithEvents TestWorker As System.ComponentModel.BackgroundWorker
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click

This is what I want, I have 12 progress bars and I want to run a background task to ping IPs and if it can ping them it starts a timer is this imposable to do?
View 4 RepliesI have a lengthy XML file that I want to search based on text that a user types in. Because it's lengthy, I want to wait for the user to stop typing for 250ms or so before I actually start searching in the background. I tried to kick off my Task, having it sleep for 250ms, then check if my CancelTokenSource had canceled because another character was typed. I'm not seeing a cancellation, though, so I end up seeing my results flash several times as the queued up search tasks complete, one after the other, after I finish typing.

View 1 RepliesI wrote some code for a program I am making to take a screenshot when the program is minimized. Thing is something is wrong with the code and I am not sure what it is. Whenever I take a screenshot the program is taking the picture with the application up and not minimized.
So what I need it to do is minimize the application then take the screenshot and then reopen the program after its taken the screenshot. for the noob question but I am brand new to the VB and only been coding it in for less then a day.

Just finishing off an update to an application written in VB.NET that used to run fine under CE.NET 4.2. Deployment platform is now Windows Mobile 6.1. The application runs in full screen, however whenever a new form is opened, the task bar, i.e. the bar with the start button comes to the fore and then the new form takes over. This is particularly annoying as I have a form that has many sub forms which are 128,128 and still the task bar flashes and obscures part of the user input screen

I wrote code for checking whether a particular process (Outlook.exe, in my case) is running or not. It is working fine when the Outlook window is open or minimized. But, when the Outlook is minimized to tray (which on the right side of taskbar), my code is not identifying the process.Could anyone please suggest me a way to get the process of Outlook (or any other program) that is minimized to tray?

View 4 RepliesI wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

View 2 RepliesI was wondering how to set a task in my program, For example if the user selects to take a screenshot on a chosen date and time the program would take that screenshot at the specified date and time. I have a DateTimePicker for my users to select a specific date and time to run the task. Since the date and time includes the date i don't think i can use a timer. And FX Cop said that timer intervals shouldn't be longer then a minute.
