GetAsyncKeyState - Make A Program That Only Listens To A Few Keys That The User Presses?
Dec 15, 2009
im trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)
Option Strict On
Imports System.Runtime.InteropServices[code].....

I have an assignment from school where the program is supposed to close when the user presses Alt X.
I have done this using Java but that was a long time ago and I can't remember how I did it. How do you do it in VB?[code]...

Is it possible to make an app (with VB.NET or any other language) that actually listens to real FM? not internet radio, or XM Radio, or any of that, but actual (Signal) FM radio, the type you listen to in a car or with a radio? if it's possible, is there any special hardware that's needed? I mean, if i wanna make it will all the consumers be able to run it? or only a selected few? Im sorry if this question is too long...
And is radio dead now or is that what people say? Am i the only one that stil listens to radio?

My goal is to create a program that just listens (no locking, no blocking, just listens) to a range of UDP ports (coming in via the internet) on my local machine and copies the traffic to a richtextbox.I have various programs that say they use the ports and I simply want to listen to what the ports have going through them, I need to make sure that the messages are still processed by the applications that they are supposed to be as well.I will NOT be sending anything. Here is the code I have so far, and yes I know I only have it on one port for now. Figured get one to work then worry bout the rest!
Option Explicit On
Option Strict On
Public Class Form1[code]..........
I have recorded as using this port is running and receiving messages...

I am trying to make a application that will bind User Desired Keys to User Desired Text. This is what I have done so far, it is not very much but it keeps crashing and visual basic is not telling me anything is wrong with it. I basically just want the user to be able to select a hotkey from a combobox. [code]

I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Label1.Text = e.KeyChar
End Sub
This detects when the user presses a character key and outputs it via Label1.text, but it doesnt work on all keys?

I'm trying to find out a way to detect when ever the user presses CTRL -ALT - DEL or Window + L to lock the PC.The code I'm using is
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (GetAsyncKeyState(17) AndAlso GetAsyncKeyState(18) AndAlso GetAsyncKeyState(46)) Or ((GetAsyncKeyState(91) Or GetAsyncKeyState(92)) AndAlso GetAsyncKeyState(76)) Then[code]....
However, as soon as the user presses CTRL-ALT-DEL the Windows Security Screen comes up and it is too fast for VB to detect that the keys have been pressed.I did a little reaserch on how to work around this issue and found that a GINA stub can be written which can delay the Windows Security Screen by some time say 2 secs which would be enough for VB to detect that the keys have been pressed.Also disabling Ctrl-Alt-Del through VB does not work because it is too fast for VB and I would like not to disable CTRL-ALT-DEL

Inside a multiline Text Box I want it so that when a user presses Ctrl AND Enter then a new line is entered. But, if they press Enter on it's own, then it acts like the Accept button on the Form. I believe this is how Facebook does it.

I am doing some stuff when the user presses the arrow keys, but I fear many controls, like the TabControl, respond to such presses as well. In the case of my TabControl, the arrow presses will make it change of tab. I don't want that.. how can I disable such?
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.KeyValue = 39 Then

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.

about a week since I started. Now I'll just ask my questions straight away:I want to make a program which allows the User to create stuff, say a survey. What I want them to be able to do is,
1. Decide the headline
2. Decide the layout of the survey
3. Import pictures
4. create new pages, like a form.
And then save this survey to a file which can be opened either by itself or by using some sort of viewer program. And I want the user to be able to put in answers to questions in the survey which wont be visible when you open the file in the viewer program. Now I dont expect you to write the program for me, just give me ideas on how to solve them, where I can learn about methods to get there and so on.

Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dojob1button.Click
Dim moneyamount As Integer = moneyamount + Int(Rnd() * 10)
moneylabel.Text = "$" & moneyamount
