Keeping An Application In Background
Jul 7, 2011
I have developed a very simple application that disables system keyboard commands (ctrl+alt+del, alt+tab, etc), hides the taskbar, hides the desktop, etc.Upon entering a password the user can 'unlock' these options.This is being used with a restaurant POS system so no accidents can happen. However there seems to be one minor issue:In a separate software package (the POS software), at specific times, any application that is running (my locking application) will get focus and end up on top of the POS software.I want my locking software to remain underneath all running applications. Anyway to keep my locking application from gaining focus? I was thinking of maybe adding some line of code to send my locking application into the background whenever it gets focus..

I use to do programming in VB3.0 years ago and decided to try it out again with VB2005. Basically I made a chat application for my coworkers so they can chat at their desk. It's a shared network and the program is pretty simple. Basically the chat gets stored in a .ini file and that part works fine, but I want to be able to show the users who are currently in the chat and I am not sure how to go about doing this, when you login to the chat it takes your name which I would like displayed and when you close the application to remove the name from the list while keeping everyone elses updated.

Final step in my application. I finally got all the requirements working, but now I need to have the application run in the background.
The application was written in Visual Studio 2010 VB, Win form app.
The requirements are as follows:
1.) run the application at start up
2.) no icon
3.) always in focas
4.) always runs in the background.
Here's the full code I have right now (working! whahoooo)
Public Class Form1
Private Property count As Integer
Private s As New Stopwatch

I am trying to call a .exe from a VB.net application. I did this using:
System.Diagnostics.Process.Start(" my file name.exe"),
This works but its UI also appears in the screen .Is there a way by which I can start the process and not let the user see it ,i.e to say can we call a .exe in the background?

I have an option for the user to choose their own background for the application. How do I then make the image save in the settings for the next time the user starts the application? (This is actual pictures not solid colors).

Is it possible to run my application in the background so there is no minimised window on the bottom bar and, if possible, so an icon appears in the taskbar? If so, how would I do it?

Is it possible to start an application not being visible? This application is a batch application and my application would look way better if I could hide this batch.

I'm feeling frustrated. I have spent hours looking for a good piece of code to capture the keypress events in any windows no matter if my application is focused or not. I need to create an application to work in the background to capture the F5 key. Does anyone have any code?

how to re-write my application (http:[url]....) to be multi-threaded using the background worker. The use case is something like:
1. User opens a binary file, it can be several Gbytes in size so reading it into memory isn't practical.
2. User can then navigate through the file in 188byte chunks, data is read from disk, decoded, and displayed for each chunk in turn.
3. User may want to search for some data or build a report. This will involve repeating the read, decode, display, function multiple times. During this looping the GUI stops responding and there is no option to cancel so I want to make it multi-threaded. So, is it safe to open the file in the GUI thread and then read from the file in the background thread? I currently use something like this to open the file once:
Dim fi As New FileInfo(filepath)
fs = fi.OpenRead()
and then in a separate sub multiple calls to:[code]..........

I want to access a 3rd Party application in the background with the SendMessage method. It just needs to send a "space" to the software to trigger an action. It is important that this is done in the background because its a periodic event (ca. every 10 seconds), and it should be possible to simultaneously work on the same machine.
I tried to use the same approach which is shown in [URL]
The code I used is as follows:
Const WM_CHAR = &H102
Const BM_CLICK As Long = &HF5&
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd

I'm writing a command-line application in .Net. The app itself is fairly simple, but it has to connect synchronously to a web-service, which in turn has to connect to a Oracle database, and those pieces are fond of taking their time.
Is there a straightforward way (without dividing my app exe in two) to continue executing but nonetheless yield execution to the command prompt?
It's Windows, so no "&". Also, I cannot use cmd.exe's "start" cmdlet.

I'm using a background worker to in an Excel VSTO application to throw up a progress dialog box with a status bar and a cancel button to escape from long running calculations. It's working really well, except for one issue. I'd like to use a Modal Dialog, so that the UI behind the dialog gets locked up, instead of a Modeless Dialog. If I use .ShowDialog() instead of .Show(), everything is great until you hit the Cancel button on the form. Following things in the debugger, the cancellation happens, it just takes somewhere in range of 30 seconds. If I use .Show() on my form, then the cancellation occurs immediately as it should.

I am using query from a SQLite database as the AutocompleteCustomSource for a ComboBox. Also, I want to load data in separate thread. My LoadData method works fine when called directly, but it fails when it is called from the BackgroundWorker thread. When it is called from the background thread, it throws a Specified cast is not valid exception on the csearch.AutoCompleteCustomSource.Add(hh("Taj")) line. Below is my code:
Sub LoadData()
Dim connetionString As String
Dim cnn As SQLiteConnection

How can i get the combo box to keep the value that was partialy keyed in and completed with auto complete.Pressing enter doesn't select the value so when you tab out it keeps the entered auto completed value. The only way to keep the auto complete value is to click on the combo box with the mouse and then tab out of it. I would like some how of being able to tab out of the combo box and it keep the auto completed value that the user has entered so as to save time entering data so no mouse clicks are needed and the data grid view can be tabbed through and all data entered from keyboard.
