Hi,
Hide the login form (after successful logon) and show the main form using
ShowDialog() method (assuming logon form is the startup form).
Or, show the logon and main forms indepenantly (from Sub Main()). That is,
show the logon form using ShowDialog and based on the dialog result (eg:
DialogResult.OK for successful logon), close the logon form and show the
main form using Application.Run().

Partha,
It is always difficult to see how people start there programs, so in
addition to Shiva, when I use a login form I start the login form in the
load event of my main form. (Did you already look at rollbased integrated
security by the way, than it can be that the login form is not needed).
However directly your question.
dim f as new loginform
f.showdialog
password = f.password
f.dispose.
I hope this helps?

Hello Shiva,
Thank you for your answere
But my code is shown below, which is written in the button_Click procedure
block
Dim MainFrm As New frmMain
MainFrm.Show()
Dim LoginFrm As New frmLogin
LoginFrm.Hide()
frmLogin is the StartUp object, on successfully login it opens frmMain.
If I hide frmLogin but still it is visible to the user.
If I hide the form, the form is still residing in the memory. Am I correct?
If so my application will be slower.
Regards
Partha

Hello Cor,
My Login from is my Startup Object.
So the form is just having 2 textbox control for entering username & Password and Button control to validate the username & password stored in the database.
If the user name and password is correct, I am loding the main form.
I am pasting the code (excluding the database part) which I ahve written in the Button_Click block
Dim MainFrm As New frmMain
MainFrm.Show()
Dim LoginFrm As New frmLogin
LoginFrm.Close()
Could you help me.
As SHIVA has written to hide the form. I have got a issue that comes to my mind.
If I hide the form, the form is still residing in the memory. Am I correct?
If so my application will be slower.
Could you please give some input on this issue.
Regards & Thanks

Partha,
Using the login as startup object leads always to difficult situations.
When you use it as a dialog in your mainform it is very easy.
I hope you do not mind, that I not try to make a difficult approach to work?
When you set it in your load event the main form, than that mainform will
never been shown you do it as the code bellow because at that time when you
did not forced it, the main form is not yet showed, so you get exactly the
result you want.
dim f as new loginform
if f.showdialog <> dialogresult.ok then
me.close
else
if in pseudocode password = false then
me.close
else
'do your load event stuf
end if
I hope this gives you an idea
Cor
Yes, you are right - the login form will still be in memory after calling
Hide(). But if you made login form as the startup, I believe that is the
only option.
How about calling those two forms separately from Main()?
Eg:
Dim x As New frmLogin
If (x.ShowDialog() = DialogResult.OK) Then
Application.Run (New frmMain())
End If
Of course, the above code requires that you assign DialogResult.OK to
frmLogin's DialogResult property on successful login.

Shiva,
It is not happening the way I want.
I am attaching the code, if you could help
Private Sub cmdGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGo.Click
Dim LoginFrm As New frmLogin
LoginFrm.DialogResult = DialogResult.OK ' On vaild Username & Password
If LoginFrm.ShowDialog = DialogResult.OK Then
Application.Run(New frmMain)
LoginFrm.Hide()
End If
End Sub
What is happening is multiple instance of Login from is opened when it encounters "If LoginFrm.ShowDialog = DialogResult.OK Then"

Hi,
Place LoginFrm.Hide() before Application.Run() because Run() will not return
until its associated forms is closed.

What form has the cmdGo button? It seems that would have been your
startup object....
Add a Module to your project, and in that module create a Sub Main.
Then set your project's start up object to Sub Main and use code like
this:
Sub Main()
Dim LogIn As LogIn
Dim OK As Boolean
LogIn = New LogIn
OK = (LogIn.ShowDialog = DialogResult.OK)
LogIn.Dispose()
LogIn = Nothing
If OK Then
Dim mf As MainForm
mf = New MainForm
Application.Run(mf)
mf.Dispose()
End If
End Sub
In your LogIn form, if the user passes your tests, then be sure to
call:
Me.DialogResult = DialogResult.OK
Or if not:
Me.DialogResult = DialogResult.Cancel
They both unload the form as part of the call....
