How To Handle Enter KeyPress Event
Jul 19, 2010
I am using the Event Handler below for the Enter Key Press Event, it is running when ever any of the keys is pressed. This is not so much a problem when the app. is running, unnecessary yes. It is giving me problems when ever I am Debugging using Breakpoints. How can I change the Handler so it only runs when the Enter Key is Pressed, doing away with the If statement?
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Chr(Keys.Enter) Then
'Different code blocks will run here depending on what
'TextBox or Label is selected.
End If
End Sub

I am trying to add to items to a combobox by using the "enter" key. It does work when I add the first item, but if I manually clear the box and add another items it does not get added to the list.
(1) I click in the combobox and type "hello" and press the "enter" key
(2) I click on the dropdown arrow and see that "hello" is in the list
(3) I select "hello" in the box and erase it, item is still in the list
(4) I type "goodbye" in the box and press the "enter" key
(5) "hello" is still in the list but "goodbye" is not
Here is the code:
Private Sub CopyrightCombo_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles CopyrightCombo.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
[code].....
if I comment the if/end if line and type "hello" the items added to the combobox list are: "h", "he", "hel", "hell", "hello" wich makes sens since the add items is run on every keypress? I know that my commands for adding items is good, I know that my keypress event is handled properly but not when I specify using the "enter" key.

I am trying to write a program that dims the brightness on my laptop. I have been unable to find the correct code, so I am trying to get it to press 'Fn & Down' on form load. The problem is I cannot find 'Fn' in the e.KeyPress I set up a small program that alerts me of the key pressed and pressing 'Fn' does not give and alert. Pressing 'Fn & Down' Gives a keycode of "None" Is there some way I can register the 'Fn' key in vb.net?

I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?

I'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.
In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?

move the focus to the next TextBox (don't worry about the Case 38, 58 etc too much I).
My Code:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'(Unrelated code here)
AddHandler Form1.KeyDown, AddressOf EnterkeyHandler 'Would like to understand this better

I have a Telerik Radgrid containing all the valid usernames and passwords that can be used to unlock functionnalities on my web page. The password is encrypted, so you have to click the row to decrypt and show the actual password. All usernames and passwords can be changed by an admin When the admin presses [ENTER] to submit the new username/password combination (instead of pressing the submit button), the new combination is actually submitted (which is fine).

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

I have a keyboard handler for my combobox1:
Private sub Combobox1_Keydown(....yaddda) handles combobox1.keydown
if e.keycode = keys.enter then
msgbox(combobox1.text)
end if
end sub
this always displays an empty message box,I need the value of the combo box before the enter was pressed, apparently the enter key empties the combobox1.text.

So I have a website with multiple asp controls. When I press enter inside by login form, the search function runs because it's the first thing found on the page.
How would I handle the enter button so that when the active textbox is for the login form, the loginbutton code actually runs rather than the searchbutton.
One last problem is that the login controls are inside a loginview so the hierarchy shows that the asp:textbox and asp:button for logging in are inside 3 tags like so:
<loginview>
<login>
<logintemplate>
//controls are here.
</logintemplate>
</login>
Just a note that all controls are asp and that all code is prefered in VB.

On the master-page their is a search text-box for the site so that shows up on all the pages. Their is also a login page screen to get to a members account.The issue is: When you are on a content page I would like when a user puts something in to search for and presses enter it will process the search request.But....If you are on the login page I would like to disable enter key for the search and if the user presses enter on the login page to process the login request.

I have couple of questions with datagridview 1.How to handle the Enter-Key when the user edited the columns value.?I mean, without changing the columns values we can suppress the enter-key by following. No problem. It's working Fine.
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
If e.KeyCode = Keys.Enter Then
Dim numCols As Integer = DataGridView1.ColumnCount
Dim numRows As Integer = DataGridView1.RowCount
[code]....
But after if I select any one column & changed the values then if I press <Enter> it's moving to next row. But I want to move it to next column..
2. With Datagridview - I have a column for date. and it's defaut format is mm/dd/yyyy. But Iam looking to read the date by "dd/mm/yyyy" format. Also if the user feed wrong date format then it has to display my Error message. "INVALID DATE"

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.

I'm trying to create an application that uses a PictureBox to display an image. I use the arrows keys to switch images and the space bar to rotate the current image. Since the KeyDown or KeyPress events don�t get fired when I click the arrow keys, I had to override ProcessCmdKey. It works fine, the problem is: the applications also has a few buttons and when I click an arrow key the image gets switched but the button�s focus change as well, worst yet, when I press the space bar, the image gets rotated but the button which has the focus gets pressed.
