Last Key Press GetasyncKeyState?
Jun 12, 2012
My Intent:I am developing an application for myself which will take a series of keycodes pressed by me(even if my program is not in focus) and execute commands associated with it.It is basically like developing hotkeys.What I Have Tried:I have searched well and tried to implement GetasyncKeyState() in my program and it works well....but the problem is, it tells if a certain key is pressed but not which key was pressed last, which is what I want........I need to know which key was pressed so that I can make a word out of it and check if it equals my predefined names to execute the command, something like this:
Dim word = lastkey
word = word + lastkey
if (word = "startnotepad")
[code]......

I'm currently using this
Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Short
Public Function GetKeyState(ByVal Key1 As Integer, Optional ByVal Key2 As Integer = -1, Optional ByVal Key3 As Integer = -1) As Boolean[code].......
But even when I do press control, the message box doesn't pop up.

I have a really annoying problem. I use GetAsyncKeyState() to determine if a key was pressed or not.Unfortunately, that event fires as long as I hold down a key. Is there any way to check if a Key was released?

If CheckBox_StartHotkey.Checked = True Then
If Not ComboBox_StartHotkey.Text = Nothing Then
Dim StartHotKey As Boolean
StartHotKey = GetAsyncKeyState(ComboBox_StartHotkey.Text)
If StartHotKey = True Then
StartActions()
[Code]...
I am trying to input the function key that a user has selected from a ComboBox (containing the function keys F1~F12 as options) into the GetAsyncKeyState(). However, since the ComboBox_StartHotkey.Text is a string, it cannot be converted into Long data type needed for the GetAsyncKeyState() function. I have tried Conversion and Parse Methods but what I try doesn't seem to work. Anyone know how to effectively convert a String (such as F6) into a Long data type for using in the GetAsyncKeyState() function in this case?
I used the tried to use the ItemData property to hold the Key Code representing the Function Key.

This code worked fine in WinForms under .NET 3.5, but since I've started using WPF and .NET 4.0, it no longer works (although I'm not sure if this is a coincidence or not). The purpose of this is to detect if a mouse button (or multiple mouse buttons) is being pressed outside of the application.[code]...

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!)

I'm creating a shooting game for my programming class' final project and I want the user to have to press "R" on the keyboard to reset their ammo back to 12. Here is like what I have so far[code]...
I've Dimmed intAmmunition globally so that it applies to all sub procedures. When I debug the game, the ammo goes down by one for every time I shoot (click) and when intAmmunition <= 0 all targets are disabled. I press the R button and they become enabled again, but then the label continues to drop from 0 to - 1 and so on.

I have this form that has all these controls on it such as buttons, entry fields, lists, and combo boxes, and I've been looking around the net for a while now trying to find a way to track key presses on my form so that I can trigger a set of code. For example when the user presses Shift + W call code that moves picture box up. I have the KeyPreview set to True on the form and I have placed this code.
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown If e.KeyCode = Keys.Shift And e.KeyCode = Keys.W Then MovePictureUp() lblMessage.Text = "Moved" End If End Sub

I want to build in the functionality so that when eg, the Key "1" is pressed it can trigger an event like eg. set the counter to zero.
I have used the following code to test the function but it doesn't seem to work. I don't know if I have placed it in the correct area or it is doing what I want it to do as there is no message box that appears.[code]...
