I need to write a piece of code that will decide weather the charactor of pressed key sould be entered to the textbox or not.
I've experimented on events:
KeyPress()KeyDown()PreviewKeyDOwn()
But non of them helped me to acheive my goal. is there any other events that i shoudl be aware of?
I have a code which registers keypresses even if it's running in the background.Is there a way I can capture the keypresses, but prevent the keypress from going to any other app? Microsoft Word and my program is running.if I press to 'Activate' button the program starts capturing all keypresses. This makes it impossible to type into Word, or any program for that matter as long as my program is activated.Once my prgram is deactivated I can type in any program normally.

View 1 RepliesI have a Form with a Textbox (Multilined) a Listbox and 2 buttons. You can insert things in the Textbox and press one of the buttons. That will add the lines of the Textbox to the Listbox.Then you click the last button and it will show you a msgbox for the number value of the Listbox1.Items.Count
Now what i want is that when you click the button it will show you an amount of msgboxes equal to the value of ListBox1.Items.Count.

I have Visual Basics 2008 express and I tried to make a autotyper, so this is my
Button1: Timer1.Start
Timer1: Timer2.Start
Timer2: SendKeys.Send(Textbox.text)
Button2: Timer2.Stop
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?

Why it doesn't work?

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")
