Receive ENTER KEY in textbox

[laroberts]

I have a form that is setup to ask for a user anme and then a password. I would like it if the user could just press enter as soon as they enter the password rather then having to push a login button. I have looked all over the net for a way to do this and have not found one yet. Any help would be great however I am very new to vb.net so please show complete code if you have the answer or I will get lost. :-)

 

Also, I will need to do a if statement in there also to validate the password.

 

Thank you!!! :D

no need to trap the keys

use DialogResult property of your buttons and form as well as Form.AcceptButton and Form.CancelButton

 

research DialogResult and Modal Forms

 

heres the gist -

(assumptions

form class is called LogonForm,

LogonForm contains text boxes, txtUser, txtPW

LogonForm has function Logon(userName, password) as boolean in its scope.

 

drop two buttons on the form, btnOk and btnCancel

set the DialogResult on the btnOk button to DialogResult.Ok

set the DialogResult on the btnCancel button to DialogResult.Cancel

 

set LogonForm.AcceptButton property to the btnOk button

set LogonForm.CancelButton property to the btnCancel button

 

in the closing event:

Private Sub Form1_Closing(ByVal sender As Object, _ 
	ByVal e As System.ComponentModel.CancelEventArgs) _ 
	 Handles MyBase.Closing
if me.DialogResult = DialogResult.Ok then
	if not Logon(txtUser, txtPW)
		 MessageBox.Show("Logon Failed")
		 e.Cancel = true
	end if
end if
End Sub

 

open the form like this -

 

with new LogonForm
if .ShowModal() = DialogResult.Cancel then
	MessageBox.Show("User Cancelled")
	End
.Dispose()
end with
' Continue with the rest of your program here

with new LogonForm
if .ShowModal() = DialogResult.Cancel then
	MessageBox.Show("User Cancelled")
	End
.Dispose()
end with
' Continue with the rest of your program here

should have read

 

with new LogonForm
if .ShowDialog() = DialogResult.Cancel then
	MessageBox.Show("User Cancelled")
	End
.Dispose()
end with
' Continue with the rest of your program here

 

My Delphi crept in there!!!
