How do I remove beep sound that comes with "KeyDown" event. When I press enter after I input a employee Id in the text box, there is beep sound. Private Sub TxtEmpName_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TxtEmpName.KeyDown

View 1 RepliesI have seen similar questions which attempt to solve this issue, but none seem to work for me so far.Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown).Below is an example of my code:

View 1 RepliesI have a method in place to capture the "Enter" button when pressed and then move to the next control in the tab order. I do this to mimic Access (my users are spoiled).The problem arises when the current control is TextBox. I changed all my TextBoxes to multi-line and it got rid of the beep. However, it also added a "carriage return" and entered it as such in the DataBase.

I have this code in the onKeyDown event of the datagridview.
Private Sub DataGridView1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
Select Case e.KeyCode[code]....
This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.
I have a service application that randomly stops without any errors in my log or in the event application log. I believe that there could be an unhandled exception somewhere in the code so I set up the AppDomain.Unhandled event to catch any exceptions. While trying to induce unhandled exceptions I have found that this event is not always fired. I added the following code to my service's Shared Sub Main method (but I orginally had it in the OnStart method and was seeing mostly the same thing)
Dim currentDomain as AppDomain = AppDomain.CurrentDomain
Add Handler currentDomain.UnhandledException, Address of MyHandler
I have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay

The strange thing is that for other forms in my code it works well and starts with the form_load function.
I'm fiddling with sessions in asp.net in a http module.The problem:
session("whatever") = "something"
is set on page_load I need an event in the http-module which is executed after page_load, and in which I have access to the session in System.Web.HttpContext.Current.Session I was looking at this HTTPModule Event Execution Order? but I can only get the session in PostAcquireRequestState, which obviously comes before page_load...
Any sample code that will cause the logic coded in the clicked event of a Button to be executed, in Powerbuilder I would code it as
Button,triggerevent(Clicked!)
this code works

my child form is a game that allows user to move using keydown event (arrow key left and right). But when i import it to MDI, keydown event doesn't work anymore. Am i missing something here?
View 3 Replieshow to use the keydown event soif you press 'A' a messagebox will popup saying you pressed A else it will say This function is not reconised i am hoping to use this knowlage to start a game so that if you press W the image will go up.

View 1 RepliesThis simple code works at child form, but not at MDI form.
Is there anything should I add or change?[code]...
I have checked my code countless times, tried other computers, and yet the keydown event will not work.
My code:Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = vbKeyRight Then
imgPerson.Left = imgPerson.Left + 500
End If
End Sub
That's all there is because I was just testing it out. imgPerson does exist, so that's not a problem.
if I press F1 on another program like, internet explorer, it will open music. When I press F1 on my Windows Form(My program), It work fine and it play my music but when i'm on internet explorer or anything else it doesn't work and I am wondering if I can.
View 7 RepliesI am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.
I need to make a simple yet cool program for my professor. The program is this: To get the program to work, the user first presses a button on the form. Then, when the user presses an up arrow on the keyboard, the cursor will change to a custom cursor (a cursor with an image of car {in .ico format} for example), when the user releases the up arrow key, the cursor turns back to default cursor -- which is arrow. When the user presses an up arrow and left arrow at the same time on the keyboard, then a different custom cursor will be shown instead of the default.
[Code]...
In my program I've used a text box and KeyPreview is True.When press the Enter-key i hope go to next row but called the default key?
