Capture Keyboard Input With Text Boxes?
Jul 13, 2011I was a professional software designer using VB6. Now that I've converted to VB2005 years later, use, with pages of unrelated information. With VB6 I could use Left$, Mid$, etc to parse keyboard input into a string. For example in the KeyPress event of a name box I could use
Case "A" To "Z"
CFName$ = Left$(CFNameBox.Text, CFNameBox.SelStart) + Key$ + Mid$(CFNameBox.Text, CFNameBox.SelStart + CFNameBox.SelLength + 1)
When converting a program from VB6 to VB2005 the software changed the line to
CFName = VB.Left(CFNameBox.Text, CFNameBox.SelectionStart) & Key & Mid(CFNameBox.Text, CFNameBox.SelectionStart + CFNameBox.SelectionLength + 1)
When writing another program I used the VB.Left(), etc, but it gives me an error. So, the question is, what is the correct way to capture keyboard input from text boxes and construct strings?
Capture All Keyboard Events?
Aug 9, 2010I've written an app with a simple textbox which attempts to identify a user from their typing habits (interval between key presses, duration key is held, time between key strokes ie a->s is quicker than a->v for some users, shorter for others depending on typing style). It's far from perfect but it does correctly identify moderate-large differences in style.I'm hoping to use this as a form of security monitor - If the typing style of the user doesn't fit a recognised pattern, report to a central server.
Of course, the next step in testing this is to begin to capture "regular" typing habits - ie when browsing, switching between apps, etc.What I can't figure out how to do is capture keyboard input for all applications (excluding the login/welcome screen, alternate desktops, etc. - I have no reason to parse that and there's probably not enough input to analyse anyway)Disclaimer: Yes, I know this comes dangerously close to writing a keylogger which is verboten but if I wanted to do that, I'd write a keyboard driver in C++ - I'm sure it would be far more streamlined and easier to obfuscate than a hulking .Net MSIL assembly. I have no doubt I'll be fending off "That's a keylogger" comments but I've hit a wall and need to ask somewhere.

Capture Keyboard Events With The Intent Of Preventing Users From Being Able To Hit Ctrl + Alt + Del
Jun 28, 2005I am trying to find a way to capture keyboard events with the intent of preventing users from being able to hit Ctrl + Alt + Del while my application is running. I've spent several hours poking around looking for inspiration but only finding unclear and half-baked examples. As such, I was thrilled to stumble across the article: Managing Low-Level Keyboard Hooks in VB .NET written by Paul Kimmel [URL] This article is insightful, comprehensive, well-written, and I thought it was a huge help. One little problem though, the code that was provided did not work, (I knew it was too good to be true!).
Now, Mr. Kimmel seemed very knowledgable and I think that he probably tested his code, so quite likely the problem is something that I'm doing wrong seeing as I am a newbie. As the article suggests I cut and pasted his code into a module in my project (solution I guess is the proper term), and I call the HookKeyboard method from a button on a form, and Presto! Nothing happens. Stepping through this code I see that the second line in HookKeyboard:

View 6 RepliesVB Or C# - Run App In System Tray And Listen To Keyboard Input Without App In Focus
Mar 28, 2010I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key [url] but it needs a modifier also (like Ctrl or Alt etc. along with my key G).

Packet Capture And Threading, Capture Library Waits For "thread Stop"
Apr 5, 2009So 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")
