Detect Whether A Program Is Open?
Jan 6, 2011
Objective : Time how long a user has been on the internet. I have never delved this deep into Visual Studio. I am suing Visual Basic 2010 Express. Please move it if you need to.
I want to have a program - that will detect running processes. If Internet Explorere EXE or Chrome or FireFox exe or any other browser is installed - as soon as that process starts the timer will appear.
When those processes are closed by the user the timer stops counting. This is possible but i dont know how. But i only want it to time just one internet process because timing them all when they are openend up at different times could cause bugs. Unless on the time form you have 1 timer for IE, 1 for FFox, 1 for Chrome 1 for Opera..

Is there any way to determine if a text file is currently open in a text editor? Or better yet, is there a way to trigger an event when a text file is opened (from any program)?

I have some code that loops in the background of a form and triggers action if the form is active (this is in a mdi forms application). I use the following to check this:
vb.net
Dim frmActive As Form
frmActive = Me.MdiParent.ActiveMdiChild
If frmActive.Name = Me.Name Then
'Do work
End if
The problem comes when that form starts another form running in dialog mode i.e. form.showdialog. I need the above code not to run while this is the case, but it still returns true when the dialog form is active and the other form is in the background.
Is there any way to detect whether a dialog is open in an mdi environment?

I want to detect if a window form is open and if it is then I would like to bring it in front rather than opening it again. I know I need a form collection for this but I want to know if there is a built in form collection that holds all the forms in VB.NET or I need to implement my own.

I was investigating on Google wether there was any sort of code that would return the current state of a laptop's 'lid'. I need to be able to find the state of the lid and be able to execute code before the defined event in Windows Power Management is executed.I have come across ExCreateCallback and stuff on MSDN however I wouldn't have the faintest on how to implement it into VB.

I'm working on a web browser named Hyvar.NET and i'd like to integrate a form of shutdown detection into it.
Currently, it simply uses a tri-option setting to decide how it opens - like this
If My.Settings.LoadLastOnStart = True Then
frm.wbTab.Navigate(My.Settings.LastOpenedPage.ToString)
ElseIf My.Settings.HomeOnStart = True Then
[Code]....
Each variable is appropriately named for its job as you can see.
However, i want to change this to react to correct and incorrect shutdowns - unexpected and user instigated ones for example. I.E: if the settings variable for the detection contained 0x000000, it could indicate a clean exit and continue as normal with a new session, but 0x000001 would indicate an unclean shutdown and present the user with an option of reopening the last session or continueing as normal, like in IE 7/8
Im 100% sure this will require a windows API call

Not sure this is a VS specific question - the answer is probably more os related (xp, vista, win7...)But at any rate - how could I go about detecting all the files that are opened while a machine is up and and running??

I have Windows XP Pro, SP3 on a Dell Dimension 9150 with VB 3.0 and all other Visual Studios up to and including VS2010 Pro.I'm not exactly an expert VB programmer, but I have written several different programs.I would like to write a VB program to run in the background and detect when the program regedit.exe/regedt32.exe tries to run.Once the regedit program tries to run, I would like my background program to pop up a message with three options. Allow, Do Not Allow and Cancel.
The Allow button would allow regedit to run.The Don't Allow button will not allow regedit to run and continue to run in the background. The Cancel button would not allow regedit to run and would cancel the background program.Can this be done?I would explain why I want to do this, but it would take too much of this thread. However, if anybody really needs to know, I will accommodate their request.

I have a custom button in IE8 which starts up my program. Now what I wanted to do, was pass an arguement such as: 'myprogram.exe /ie'
From the IE8 button, and well my program will do rest from there. Now my program adds the button just fine, shows up fine, all that works. But each time i'd add an argument after my application path, IE8 would say it can't find the program. If you want to test this out, goto run, type in gpedit.msc, then 'User Configuration'->'Windows Settings'->'Internet Explorer Maintenance'->'Browser User Interface', and double click on 'Browser Toolbar Customizations'. And in the small window that pops up, is an option for adding custom buttons to IE. I was using this for testing purposes, since it was faster to edit a button here than in my program. When you add a button you choose the executable to link it to. But if you add any arguments after it, IE will simply not be able to find the program. Even if that same command works when you type it from 'run'.
So, now my question is, since apperntly you can't have any arguments in the button, is it possible to detect what executable starts your program? For instance, detect if iexplore.exe started up my program?

Is there a way to detect a Chinese character in a string which is build like this:
dim test as string = "letters 中國的"
Now I want to substring only the Chinese characters. But my code is database driven, so I can't substring it, because the length is always different. So is there a way I can split the string, from the moment I detect a Chinese character?

How would I make my VB Program detect mouse clicks? I want the code in a timer. So if I turn the timer on, my program will detect a Mouse click and then do the rest of the Timer code. And after the timer code is done, I want it to do it again until the timer is closed. So if the timer is on, every time I click the mouse, (anywhere on screen) it will do the rest of timer code.

The purpose of the code below is to scan a program of mine to detect a pixel color change. It loops through until a change is detected. It works fine for about 10-15 seconds and then I get an ArgumentException was unhandled error. So far this has happened on two different lines at separate times...
Image = New Bitmap(Rec.Right - Rec.Left, Rec.Bottom - Rec.Top)

I am trying to write a VB program to automatically detect and identify a particular device that will only communicate to my program when I have 2 or more devices plug into the USB port. One way of doing it that I can think of is to scan through the available port and do a write and read to identified the port. But that would take up a lot of time if I were to scan through say 5 available port.
