VS 2008 Handle Keypresses On The Form?

Feb 26, 2010

I have the following code to handle keypresses on the form:

Private Sub Form1_KeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Debug.WriteLine(e.KeyCode)

[Code].....

The first time I press any of the arrow keys the code is not executed and a NumericUpDown(NUD) on the form gets the focus. The rest of the times the arrow keys are pressed everything is fine, until I click on a button. Then the problem repeats, focus NUD, then fine.

How To Get Multiple KeyPresses At Once

Jun 20, 2008

I am currently creating a Space Invaders game. Basically what I want to do is being able to move and shoot at the same time. The problem is that whenever one button is pressed to execute an action it cancels out any other button being pressed. I don't want that to happen. Currently I am just using Key down. How I can have multiple key presses at once?

Private Sub frmain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Dim Loc As Point
Select Case e.KeyCode
Case Keys.Left
[Code] .....

That's my code. This is basically the last thing i need done in my project.

How To Simulate Keypresses And Releases

Dec 28, 2010

How can you simulate keypresses and releases? I know you can essentially hit a key with Sendkeys.SendWait, but how can your code press and hold q, for example? I essentially wish to be able to call something like press("q") and release("q"). The effect would be the same as physically holding them down.

Simulating Keypresses With Sendmessage?

Nov 30, 2009

I use keybd_event and mouse_event to simulate keypresses. I want taht to still work when the user is switch (Xp supports several users as we know).

Well, it doesn't.

I've heard sendmessage is more reliable,.

I manage to simulate click easily.

SimulateClick2 = SendMessage(hwnd, BM_CLICK, 0, 0)

Now, how to do so to simulate keypresses?

Can't Detect Keypresses When A Button Is Present

Mar 31, 2009

I've started building a small game where you move around a PictureBox control with keystrokes using the arrow keys. Everything was working fine....until I added a button.

Now the button steals the focus so that every time I hit an arrow key hoping to move my image, it just selects the button.

Is there any way to make the button selectable only by mouse click?

TopMost Form - Messages Form Would Be Hidden By The Main Form

Nov 20, 2009

I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.

What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.
