I am learning C# after tried Java. Ive tried to program a program that can detect keystrokes, however when i add onKeyDown on my form it work but only one key at a time. So ive tried to add my e.keycode detect to a timer and got error. private void key_Tick(object sender, System.EventArgs e, KeyEventArgs e)
That wont work and the timer wont run becuase i have 2 Args. Im really lost and do not really understand

View 5 RepliesWhen a user types into a VB.Net textbox, I want to detect the key press (assuming I cannot read the text from the textbox after its written). This is easy for English (by using e.KeyChar or Keys.[A, B, C, ...etc]). However, if I change my default keyboard in Windows from English to another language, say Arabic or Farsi, still the English characters are detected (although Arabic or Farsi is being typed in).

Before anyone tries to close this thread thinking this is for malicous purposes, let me tell you that it's not. What i'm working on is an application to save screenshots to files as soon as the 'Print Screen' key is pressed, as Jpegs or what ever. What i want to do is be able to minimize the application and I still want the application pick up on any 'Print Screen' presses, and save the screenshots. I've tried using the KeyPress event, but I soon realized that it only worked when the application had focus. I plan on using it to save screenshots every time I press 'Print Screen'

Reason for asking: I want to stop a user from changing tabs in a tab control.
I want to be able to detect when the user presses F10 or Ctrl+F10 outside of my program, and upon receiving the key press, it will send text to whatever they currently have selected (e.g. a text box). How can this be accomplished in the simplest way?

I am trying to modifying the "Math Quiz" tutorial to be more user friendly.
The initial tutorial does not consider the users efforts to answer the math problems as quickly as possible.
The problem is that you must use the mouse or tab key rather than the "enter" key to move to the next control after answering. I believe using the "Enter key to be much more intuitive.
Therefore, I wish to modify the program to either:
1. Check the KeyPress event of the NumberUpDown controls to watch for the "Enter" key to be pressed, and if it is, check to ensure that the current NumberUpDown control is not empty (= Nothing) and if both are True, to then TAB to the next control in the TAB order; OR
2. Uses the PreviewKeyDown event to transpose the "Enter" into a "Tab" automatically so the application will then TAB to the next control in the TAB order.
With all of the new changes to VB 2010 from the last version I actually used professionally (VB6), things are REALLY different, so I no longer know how to accomplish this same task in the new manner. especially if it contains working CODE, because I have always learned better the first time from an example. here is my version of the tutorial Code:
'--- Create a Random object to generate random numbers.
Private objRandomValue As New Random
'--- The Integers will store the numbers for the
' addition problem.

I need to find out how to detect keypress's outside of my form
View 1 RepliesI have a console application and i want to run some code but at the same time I want to have the ability at any given time to press CTRL + SHIFT + S to stop it,
Now I tried doing something basic like this which would stop if you press X at any given time:
Dim stTest as string
Do Until stTest = "X"
stTest = console.ReadLine
console.WriteLine("you didn't press X yet...")
The problem is that every time before it writes that line it will wait for the user input because i have "Console.ReadLine" on there, I don't want that to happen, I want it to keep going until a set of keys are pressed.

I couldn't manage what the matter is not even after searching. Here my question goes:I need to do a simple task (close my form on pressing escape key) and I use the following code:
Code:
Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
Select Case (e.KeyData)
'Close on Escape
Well , it works when I click escape my form closes , but.. if I have pressed by accident or some else matter any of the arrow keys (up , down , left , right) before escape and then hit escape nothing happens. I checked if any other key does that and as I see it does not.
I just want to ask why my KeyPress event is apparently not working. What I want is that when I press the letter m, the selectedindex property of my listboxes would change. Here is the code;
Select Case Asc(e.KeyChar)
Case 13
Try
tray.ListBox1.SelectedIndex = tray.ListBox1.SelectedIndex + 1
[Code]....
I also want to know what the "e.handled = true" is statement for. I set the KeyPreview property of my form to false and true but it's not working as well. the KeyPress event should be triggered regardless of the control within the form that is in focus.
Is it possible to capture a keypress with my application, even if the application isn't focused?And if it is, could someone please point me in the right direction? (I.E things to look up, tutorials)
