How Do I Keep A Window As The Top-Most Window Only In My Application?

There doesn't seem to be anything about it :S

I offer this feature in my latest app. Here's my code, verbatim:

Private Sub AlwaysOnTopToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AlwaysOnTopToolStripMenuItem.Click
 
    'Save Setting
    If SaveSettingsToolStripMenuItem.Checked Then My.Settings.setAlwaysOnTop_Checked = AlwaysOnTopToolStripMenuItem.Checked
 
    Me.TopMost = Not Me.TopMost
End Sub

AlwaysOnTopToolStripMenuItem has the property CheckOnClick = True

Thanks, but this isn't what I'm looking for. I have a Toolbox form, and it's meant to stay on top of all other windows only in my application (not a dialog). When the application loses focus, this window is no longer topmost.

if you use .showdialog instead of .show, your form will stay topmost within your application. but, it'll be displayed as a modal dialog

.ShowDialog() instead of .Show()

Edit: slower than paul.

Thanks, but I said I didn't want a dialog, just a tool window that sticks on top of all the other windows in my application while my application has focus, then when another application is selected, this topmost property turns off.

I'm not sure if there's a specific way of detecting whether the application has "lost focus" in .Net, in the good old days of VB6 and beyond you would use sub-classing. There are plenty of examples that can probably be leveraged into .Net if needed.

If you can detect when your application loses focus you could then set the TopMost property of your form to False as necessary.

An example of how to trap that in VB6 is here.

Thank you , but the msghook library appears to be VB6 only

you can use a wndProc in vb.net to trap messages
