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].....

Event That Occurs For All Button Presses?

Feb 20, 2012

I have a system with 26 buttons but the buttons actaully run the same code; aside from the fact that the index number is used to distinguish between them (es, I know index values are out so I am using the object's name (btnKey1, btnKey2, etc).

Is there any event that occurs for all button presses or do I need to write the same line for all 26 events (actually 52 since I am using MouseDown and MouseUp - will get worse when I want to use the keypress side)?

Detect When A User Presses CTRL -ALT - DEL Or Window + L ?

Dec 2, 2010

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

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.

For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

VS 2008 Testing Key Presses In Succession

May 29, 2010

I need to determine if a set of keys have been pressed in succession. For example, if I'm looking for this combination: Up, Up, Left, Space, then any key that inteferes with the order would start it over.

I tried doing a basic test to see if it would be as straight forward as I was hoping:

VB.NET

Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.Up Then

[Code]....

For some reason, it doesn't let me continue the sequence. I put a MessageBox on the second "Up" and it triggered when I pressed it just once.
