My requirement is as soon as my form get load it should get hidden or invisible.The user should not be able to even get the look of the form.I have tried this at load event but its not working.

 Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
me.hide
me.visible=false
End Sub

I have tried Me.Hide and Me.visible but its not working.Can i do it on load?

Is there anyother way please suggest.

This tactic sounds more like spyware/virus than any feasible reason....but hmm

For example if you had a log-in form you could do something like (untested)

Dim myForm as New frmMenu() 'go to the menu after logging in
Me.Hide() ' temporarily hide the log in form
myForm.ShowDialog()
Me.Show()  ' when user closes the menu, show the form again

Unfortunately you can't set Visible to false during the constructor or the Load() event, but you can do a couple of things:

* Create a one shot timer for 100ms - start the timer during the Load() event and have the timer make the form invisble.

* You can bash the CreateParams() method to make the form invisible by default.

* You can override the form's WndProc and prevent the form from showing during the WM_CREATE command.

There is another event that fires soon after from what I recall which you can use instead, can't remember what it is off the top of my head though and it's far too late to be digging around in VS.

A simple way is to put the code in the 'shown' event of the main form.

Example:
Private Sub Form1_Shown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Shown
Me.Visible = False
End Sub

Change the WindowState property to Minimized and ShowInTaskbar property to False.
Add Me.Hide() to the Form_Load sub.

set the location of the form so that even if it's "shown" for a second it's not in the visible area of the screen...    like  -5000,-5000     then later change the location property to a value like 200,200

just be sure to check the users desktop size and screen count info.... i hate programs that assume all new windows belong inside screen zero when i have two monitors and the app is in screen one.

if the parent app is in screen one then put new windows in that screen please !!!
