child form control box

[Arg81]

Hi Guys,

Even though I have set each individual form to not show the control box (minimise, maximise, close), when it is opened as a child form in my MDI container then a control box is shown.

Is there any way to get around this, or is it a bug with the way the MDI container opens child forms?

cheers,
Luke

What code? My whole project?!?!

Basically each form is set on the properties tab to have controlbox = FALSE.

Then on my main menu, when an item is clicked it does the following;

dim frm as new frmForm1
frm.MDIParent = me
frm.show

......that's the same for every form opened on the main menu.

Well, i thought you set that programatically

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Me.ControlBox = False 

End Sub

Otherwise it is not bug at all ... actually, take a look at the attached project below

sorry, slight misunderstanding, I assumed you wanted the whole lot!!! hehe....

downloaded the zip and looking at now...cheers!!

ah ha - forgot to mention that I maximise each form within the MDI Parent , so when you're example Form 2 is maximised, it shows the control box for that form, even though it is set not to....

Just Don't touch anything within properties window but rather put this code in load event ... as it follows:

Private [/color][/size][size=2][color=#0000ff]Sub[/color][/size][size=2] Form2_Load([/size][size=2][color=#0000ff]ByVal[/color][/size][size=2] sender [/size][size=2][color=#0000ff]As[/color][/size][size=2] System.Object, [/size][size=2][color=#0000ff]ByVal[/color][/size][size=2] e [/size][size=2][color=#0000ff]As[/color][/size][size=2] System.EventArgs) [/size][size=2][color=#0000ff]Handles [/color][/size][size=2][color=#0000ff]MyBase[/color][/size][size=2].Load
 
[/size][size=2][color=#0000ff]Me[/color][/size][size=2].ControlBox = [/size][size=2][color=#0000ff]False
 
[/color][/size][size=2][color=#0000ff]Me[/color][/size][size=2].WindowState = FormWindowState.Maximized
 
[/size][size=2][color=#0000ff]End [/color][/size][size=2][color=#0000ff]Sub

Cheers

Kulrom.

Still the same, even if I put that code in!!! The control box is still there, although the close icon is now not enabled, but the minimise and restore-down buttons are still there!

Thanks

It's been a while, but I beleive you need to set the Dock property to Fill rather than maximizing the ChildForm.

 

[Arg81]

just tried

me.dock = dockstyle.fill

but that didn't do a thing.

assume I would put the above code into the child form LOAD, but still have the parent calling frmChild.MDIParent = Me ??

Thanks,
Luke

Hi Luke,
It is very strange because that same code works just fine for me ... take a look by yourself at the attached DEMO project

Sussed it - think it's a bug???

If WindowState is set to something other than Normal in properties, and having me.windowsstate=windowsstate.maximised and me.controlbox = False set on Form_Load, the form will still show the Control Box.

Resetting the property to Normal, then having Me.WindowState = WindowState.Maximised on form load (with me.ControlBox = False), the control box doesn't show.

Thanks!
Luke

It may be but as i told you: Just Don't touch anything within properties window and get accomplish it through code
However, you are working on solution rather but finding bug/s ... happy coding Luke

Cheers
