Capture Keypress / Let User Pick Their Own Start/stop Key?
Oct 29, 2011
Currently I have the start-key for my vb.net application hardcoded like this:
GetAsyncKeyState(Keys.F2)
Where vb.net sais "F2 As System.Windows.Forms.Keys = 113" on mouse-over.But I want my users to be able to pick their own Key. If I make a drop-down box (combobox) and pre-define some choices in there (Like ESC or F3), all those choices are strings. How can I convert those strings to a System.Windows.Forms.Keys integer? Also, I'd like it to also be possible to "capture" a single keypress. So they'd click the "capture" button, and the next key they hit will be saved as the start/stop button. But I wouldn't even know where to begin looking for that one.

I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?

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")

i am trying my hand in visual basic 2010
it's a windows form program, what am i trying to do is, when i press ctrl+v (yes pasting) in other program, whether it be notepad or a text box, something also happens in my program.
So i need to capture the keypress event when my form does not have the focus.I would hate to create a windows service for this, but if there is no other way i might have to do it.

I created 3 timers, i want each timer to take turn start which means timer1 stop then timer2 start, once timer2 stop timer3 start. But my code seem to be running together once i click the play button.And is there any ways to easy control how my picturebox move? Because my code for controlling it movement need to keep finding the correct number for it to move.

I need to run a do while loop or some way of starting a search directory loop, then if a user presses another key, it will stop that current search, and restart with the next letter entered. I appreciate any help given and insight. I am basically trying an incremental search feature, but currently whenever a user types in one letter, it does a full search, then on next letter it searches again. I want it to stop if they are still typing in letters.
If SearchTextBox.Text <> "" Then

I am new to VB and what I would like is for the user to pick a item from the drop down box and from there; there would be a list that pops up to the side with that users pick list of attacks. I am trying to do this for every item in the drop down box. So, when the user changes character type it automatically changes the list to what the user picked. Below is two pictures one with the ?amazon? picked and the other with the ?sorceress? picked. To give you an example of what I am trying to do. My question is what the best way of doing this?

A spreadsheet formatter that I made for the department opens and closes Excel spreadsheets in the backround. If someone opens Excel while the macro is running, it stalls the entire program. I need a way to sense Excel opening, then stop it, preferably with a message box saying what just happened.

I want to create a simple form with 2 buttons, one to end the program and one to log the user off, I have done this successfully and have everything looking and working as it should. However, I want to force the user to pick one of these buttons before using the machine, my idea was to trap the mouse in the form so the only thing the user can do is select a button. My question is how can I do this?

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

what is the method to tell when a user starts or stops a process? My company makes a software package that allows a tie in from vb. I want to make a package to allow me to start and stop the software remotely and to monitor when the software is running or not.Ideally there would be some sort of event in windows when the user starts or stops the software. I imagine there is some sort of way to do this with a timer, but I am sure that windows will have some sort of event process when the program starts. I have googled this and looked through the xtremevbtalk forums for this but I am not quite sure as to what keywords to use.

I'm very new to Visual Basic, and have just installed VB Express 2008 from a Sams book titled, "Teach Yourself Visual Basic 2008 in 24 Hours", by James Foxall. I've managed to make it through most of the book, which was very helpful in getting a quick jump start, but I find that I am still "not quite getting it" yet.
I've written a program that has a "Start" and "Stop" button which are suppose to control the logging of data through a serial port. When I click the Start button, the serial port gets initialized, opened, and then I go into a Do-Loop-Until loop to process the incoming data stream, and that is suppose to stop when the Stop button is pressed. However, I haven't figured out how to implement that.

I am writing a Windows Forms Application using Visual Studio 2008 Pro .NET version 3.5 with STRICT and EXPLICIT options both ON.
I am having trouble using ".Start()" and ".Stop()" for my stopwatch method from other methods. I have tried several different methods of writing the line that calls the start and stop, but none work, and VS keeps sending me in circles with its correction suggestions.
Form Level
vb
Imports System.Diagnostics
Class Level
[Code]....
and promptly gives me the same error with no options for correcting it. The same thing happens for the stop command.
