I have a textBox and a button's click event used to add the textBox.text to a listBox. Is there a way to add the textBox.text value to the listBox without having to click on the "Add" button. Such as, simply typing the text and hitting ENTER on the keyboard?

View 2 RepliesIn VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp
Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp
How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?
So I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?

How can I get the button fields and how can I invoke the button press event programmatically.
View 1 RepliesIt was pretty simple in VB6 to invoke the 'click' event of a command button (i.e.; btnNext_Click). I am having difficulty trying to do the same think in VS2008.
I am getting errors at line btnNext_Click(): Error1Argument not specified for parameter 'e' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
Error2Argument not specified for parameter 'sender' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
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!)
I have a series of radio buttons in a Group Box on my main form. When I run the program, the first step is Sub New and the InitializeComponent() procedure.
It then immediately goes to the first radio button CheckedChanged event. This even currently contains some programming to access information from a database table. However, the program hasn't even gone through the process of opening the database and logging in. This doesn't happen until after my frmMain.Load event. However, this happens after the CheckedChanged event for some reason. So now that I have included the data requirement, I am getting errors because the reader is opening before the connection opens. I know I can set up a Try....Catch....End Try to avoid a user error, but ...I thought the form would have to load before anything about the controls happens and then since I haven't clicked anything, I am not sure why the event is triggering.
I have this code to create a new button
Dim NewButton As New Button
frmDownload.Controls.Add(NewButton )
This works. But I want to change what happens upon clicking NewButton. It should start an application. I tried NewButton.Click but that event doesn't exist.
I use this code that works well.
