How To Modify Key Presses
Jul 31, 2010
I am trying to create an application that will enable me to type in my local language. For that I need to modify the key presses. For example when I press key A it should change it to ”. Also I would like to know how to detect double and triple key presses e.g. shift + W and ctrl + shift + J and remap them to a different character. Also I would like to know how to detect a text string like and replacing them with other string like member. I have found a code that modifies key. But when I tried to change key A to key B it produces AB. I am including the code below. Hope I have made myself clear.

I am writing a program that expands the usage of the clipboard, but I need to tell when the user has either cut, copied, or pasted something so I can write code accordingly to that. I need to know how I can check to see when the user has entered a command like this.

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 just finished building my robot and now I am trying to come up with the code that goes on the computer to control the dang thing. Right now I have a thread that constantly loops in a do until loop that will never be true. Inside that loop the program should check to see if the w,s,a, or d keys are pressed if they are then it finds out what key has been pressed and sends the appropriate value to the robot. If no key is pressed then it should send the stop value to the micro controller which halts the robot until a new key is pressed.This is the basic way that I thought the code should be constructed although this code DOES not work.

I would like my webbrowser1 to press tabs. I used this code to press tabs:
SendKeys.Send("{TAB}")But it clicks tabs, where ever there is a focus on an object. I want it to press tab inside the webbrowser1 without have to have the program focused.

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]...

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)?

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.

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

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

I have a code which registers keypresses even if it's running in the background.Is there a way I can capture the keypresses, but prevent the keypress from going to any other app? Microsoft Word and my program is running.if I press to 'Activate' button the program starts capturing all keypresses. This makes it impossible to type into Word, or any program for that matter as long as my program is activated.Once my prgram is deactivated I can type in any program normally.

I'm making a keyboard test that will test to make sure each key, in a specific keyboard layout, is working correctly.
Each key, with the exception of the first, will be disabled by default. I need to have the tester press the first key (Escape) and if it works, disable that key and move on to the next, (F1). This process will repeat until all the keys have tested.
The dilemma I have is figuring out how to test each keystroke, in order, without making a huge nested if statement.
The only method I could think of, at the moment, was to check the Enable property of the control and then check for the correct keystroke. But, again, doing this would make a huge mess.

I need to add a code to this piece of code.
Quote:
SetCursorPos(714, 813)
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)[code]......
When the cursor presses on the location, it will write in the box the word Enter. Now what I want it to do is, instead of writing the enter, it would get the word from a textbox1 and would write it in the box that the cursor pressed.

is it possible to have 2 simultaneous key presses with the keydown event. I have a keydown sub with 2 sets of keys mapped to move 2 different pictureboxes. But when I press a key for the other picturebox, the first one stops moving. How do I get both to work at the same time?
