Status Bar Question

[Rat]

Status Bar Question - [RESOLVED]

I have three forms, one as a parent, and two childs.

I've placed a statusbar on the parent, how do i make the statusbar controls visible on the other forms i have in the workspace ?

- Thanks.

I would suggest creating a public method in the parent to actually set the text of its own status bar and passing a reference to the parent form to each child. If your app uses MDI then you already have a reference, otherwise I suggest passing one in each child's constructor. The child forms can then assign that reference to a class level variable and call its public methods, including the one to write to the status bar, whenever they like.

Could i get a example bro, if it ain't too much of a trouble.

Are you using MDI?

Are you using MDI?

Yeap bro, using MDI.

Something like this in the parent:

	Public Sub SetStatusBarText(ByVal text As String)
		Me.StatusBar1.Text = text
	End Sub

Something like this in the child:

	Private Sub SetStatusBarText(ByVal text As String)
		DirectCast(Me.MdiParent, Form1).SetStatusBarText(text)
	End Sub

I've used Form1 as the type of the parent but you can change that to the correct type. The MdiParent property is of type Form, so you need to cast it as the correct type to access members specific to that type. I've put the code in the child form into a procedure but you can call the parent method anywhere you like in the child.

Thanks bro, i've got it.

So bro, i guess the DirectCast method, can be used for most controls, when working with multiple forms and MDI ?
