Return Key

I am new to VB.Net and I am developing a stand-alone app
that will only be using a RF scanner to enter
information. I was curious if anyone knew of any articles
or source code on how I could get the text box to execute
to TAB/ENTER when a certain number of characters have been
reached within a text box.

Chris,
maybe this code will help you. Place 2 textboxes on the form and write this
code

Private Sub TextBox1_KeyPre ss(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyPressE ventArgs) Handles TextBox1.KeyPre ss
If Len(TextBox1.Te xt) >= 5 Then
e.Handled = True
Call Done()
End If
End Sub

Private Sub Done()
TextBox2.Select ()
TextBox2.Text = "No more characters. Do something else"
End Sub

You can call any sub or function instead of my DONE sub

Will this code recognize when the user presses the ENTER
key?

By doing a "Tab", i'm guessing you mean shifting the focus
to the next textbox. That would be done like this:

Private Sub txtOne_TextChan ged(ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles txtOne.TextChan ged

'where txtOne and txtTwo are two textboxes on the form
If txtOne.Text.Len gth = 5 Then
txtTwo.Focus()
End If
End Sub

By doing and enter, I presume you want some action(s) to occur
when the box is full. For this, put the action into a sub(eg. MySub)
and call the sub like this:

Private Sub txtTwo_TextChan ged(ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles txtTwo.TextChan ged

If txtOne.Text.Len gth = 5 Then
Call MySub()
End If
End Sub

Hope this helps,

I have the following sample program, which can convert function object with 1 argument into function object with 2 arguments. It can also do + between function object of the same type. The last line is very long. I'm wondering if there is any way to suppress it. I can only think of typedef. But I'm not sure whether I can use typedef for the return type. Would you please help me? Please don't be daunted by the length of the code.

I am trying to verify that I correctly understand something I saw in the DB2 Information Center. I am running DB2 Personal Edition V8.2.1 on Windows. I came across the following in the Info Center: To return a result set from a procedure to the originating application, use the WITH RETURN TO CLIENT clause. When WITH RETURN TO CLIENT is specified on a result set, no nested procedures can access the result set.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
