VS 2008 Unable To Use The Keyboard Event?
Nov 10, 2009
Im trying to send keys to cod4, Jump (space) works perfectly after i added the keyup after keydown, Before i added Keyup for W (move forward) it would jsut spam and keep running forward, but after i added keyup it doesnt move forward at all, not even a little bit
note: it does send W and space to regular windows,
ElseIf command.Contains("keyboard=space") Then
Call keybd_event(System.Windows.Forms.Keys.Space, 0, 0, 0)
Call keybd_event(System.Windows.Forms.Keys.Space, 0, KEYEVENTF_KEYUP, 0)
[code]....

I have the following code which I use in another Form and it works perfectly. I copied the same code to another form, changed the controls, keys combinations, etc., but the keyboard shortcuts do nothing at runtime. None of the key combinations work, it throws no Exceptions,I put a MessageBox in the F1 KeyDown conditional, but it doesn't show. That tells me that it's not Handling the KeyDown Event.[code]

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work. Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas? I'm trying to mimic Windows calc.exe for a school project and thought I'd try throwing in a few extras such as numeric keypad functionality.

I wanted to make a calculator. Its fully made and everything but I recently wanted to add more to it. Only thing I can't figure out to do is to make keyboard functions. Like, if I want to type in the numbers instead of clicking the buttons on the calculator to input it into the calc. [code]....
It works to a certain point but i found out that the timer input multiple integers when pressing a key so I thought of about turning off the timer and then having the timer turn back on somehow but that is as close as i can get.

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown If e.Modifiers = Keys.Control AndAlso e.KeyCode = Keys.A Then
[Code]...
And whenever I click control-b (on keyboard) it inserts the bold tag twice.why does it do that? i use to have that code in a button, and the keyboard event would lead to button1.performclick but now when putting the button code in the keyboard it adds the tags twice

Private Declare Sub Keyboard_Event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) [Code] I know the KeyCode when i call this function. Example 13 is the keycode for "Enter". But it says that theres an error on syntax cause KeyCode is an integer not Byte. What kind of variable does it need there? I mean does it need the keycode (which is a number) or a character e.g. "a"? [Code]

Maybe my questin was too impossible to unerstand, so I figured out how to ask it in more simple way. I suppose it can be best done in Visual Basic simplified code.

So question is how to describe in Visual Basic [Escape_key_was_pressed] function? When user don't hit Escape key, then program must NOT STOP for asking user keypress[Escape_key_press], it must go on with clicking on desktop to the end of program. SteelAce

I've adapted the code from this link to use the WinXP on-screen keyboard (osk) for a touch-screen application written in VB.NET v3.5. The osk fills the bottom half of screen etc. and behaves fine except for one little quirk. If the user clicks or taps anywhere on the 'background' area behind/between the virtual keys (within the main osk window), the color of the area changes to that of the keys when any further key subsequently gets focus. The outline of all keys is then lost because they are visually merged into the osk window background. The osk must then be terminated and re-launched to remove the confusing appearance.
This behaviour only occurs when the osk window is set to the child style (i.e. when the menu is hidden), using the SetWindowLong P/Invoke function - e.g.
SetWindowLong(OskProcess.MainWindowHandle, GWL_STYLE, WS_CHILD)
It's as if the entire area behind the keys is being treated as another key when tapped/clicked, whereupon its color is 'restored' after losing focus.Is there any way to intercept and somehow override the focus event of this osk background area?

I've got a bug in my program that I can't work out, during a paint event. The only way I can think to solve it is to watch the screen being updated one thing at a time. Problem is, I've put a break in and then I try stepping through the program one line at a time, but when I go to look at the screen it's blank - probably because I'm in the middle of a paint event? Is there some way that I can get my screen to update after each command?

Winforms, VS2008 I have a mainform that has 2 usercontrols: UC1 and UC2.UC1 has a treeview with treenodes. UC2 has tabControl with few tabPages. Selecting different nodes displays different details view in the TabControl's TabPages. What I need is canceling the event when the user has selected a node in the treeview, then he selects another node (i want to be able to cancel this last event:selecting another node, all depending on a certain logic)I mean: When the user is working on a tabpage in the tabControl, when he clicks on a different node in treeview (different from the currently selected node), before displaying the new node's details in the TabControl, I perform some logic, then depending on that logic, I set
e.cancel = true in the UC2 Validating event handler. (Rememebr UC2 includes the TabControl and the user, supposedly, has the focus on a control somewhere in TabControl)
But mysteriously, the event gets never canceled and the user still moves to the next node, displaying its details in the TabControl, although I set e.cancel = true.

My main goal is to trigger an action in my program with a key, F6 and F7 in this case. I want this trigger to work regardless of whether or not the window is currently active. These keys are meant to stop and start the code. I've searched everywhere I can think of and can't find anything. The closest thing I found was that to simulate an F6 or F7 keystroke it's something like &HBAF6 and &HBAF7. I also found somewhere that you can make a global (something like that) hotkey, but I don't want that. I only want it to work when my program is open.

All I want to do is to stop my application at a certain point, wait until a certain key is pressed - say for example the space bar, then continue execution. How simple is that! Any other normal programming language, this would take me a few secs - but not VB2008

I have created a virtual keyboard like the "Windows onscreen keyboard". So, I have used the method sendkeys.But if I click on the button, it doesn't write nothing.
I think I have a problem with the FOCUS.As you can see, the "Windows onscreen keyboard" is always on top.This doesn't happen to my form. How can I do?

I was making a program where it takes text from a textbox on one form, and places into a textbox on another form. If the first text I am taking says "test" Then the buttons code would be:
Form2.TextBox1.Text = Me.TextBox1.Text
This works, however, if there were two textboxes in the first form, and I wanted this:
Form2.TextBox1.Text = Me.TextBox1.Text
Form2.TextBox1.Text = Me.TextBox2.Text
- this would not work because one of them will override. I wanted to know how I could send a key into the form just once. I have tried this:
Form2.TextBox1.Text = Me.TextBox1.Text & ("{ENTER}")
Form2.TextBox1.Text = Me.TextBox2.Text

Can i put my app in some kind of wait state for a certain key on the keyboard before continuing? But that key can be targeted to any window, not just my app. My app would be out of focus and i hit that key on the keyboard and it would act.
