I am a newbie to this forum. I searched across a lot to find a way in VB.net how to capture the keyboard and mouse events scoping to the whole computer. Basically what I want to do is make a keyboard and mouse macro recorder application, so that the regular job of starting the same programs again and again everyday might be automated.
[Code]...
I'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.
I have USB RFID reader which acts like a keyboard; how can I capture the keyboard Input?
As Windows 2000 and Windows XP obtain exclusive access to Input and Output reports for keyboard/mouse devices.
I am trying to capture keyboard events in my vb.net applications. I am able to capture all the single key events. I am not able to capture (<) key which is (shift + ,) and (>) key which is (shift + .).
View 1 RepliesI 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?
I 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 10 RepliesDoes anyone know how to capture (Record) the Windows desktop and save it as a '.avi' or '.mpg' file. This functionality can be done using screen capture / presentation programs like SnagIT:[URL]..I have found many examples showing how to capture from a webcam using the 'avicap32.dll' DLL file but these dont help with this problem.
If you are asking why i dont just use SnagIT its because the interface is overly complex and building my own version would allow me to intergrate it into my existing programs.

View 2 RepliesI am creating a DIY calculator.The one in W7, I can't hardly see. Mine is much simpler and larger.I currently have buttons for numeric 0 - 9, Add, Subtract, Multiply, Divide, Clear, Enter, and Decimal Point.There is a label at the top with displays results.If I use my mouse to select the buttons, then everything works okay. However, if I use the keyboard, I get strange results.I thought it may have been my old keyboard so I changed it.No difference.If it's not in the hardware, then it's in the code.The section below is what I have for keyboard use:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Ch = e.KeyChar
Select Case Ch[code]....
For each of these, there is a corresponding Button_Click even farther down in the code. Since the mouse click on the buttons on the form works properly, the problem must be above. I can't see it.

View 3 RepliesI am kind of amazed that there is no answer to this anywhere and I mean anywhere. I am looking for a way to disable the keyboard (actually all input) on a computer. There are several threads about it but no one has ever posted any serious, working code. I know someone is going to inevitably ask "why would you want to do that"? Actually why I want to do it is immaterial but if you must know... I am playing with a "USB Keylock". When this USB Keylock is not present in the computer I want to disable the keyboard. When it is present I want to enable the keyboard.

This is for a World of Warcraft and it is legal. I thought that I would use setWindowsHookEx, but I can't figure out how to set it up that it only takes the input from one window and not globally.Can anyone recommend the best way of cloning keyboard and mouse messages ? or give me an example of how to set a windows hook for only one program ?
