Hi,

How can I force a form to the foreground no matter what application is
in front?

Thanks!

Hi Seth,

No TopMost will not do. The form cannot be TopMost.

It's a hidden menu form and when he user presses Windows+I the menu form
must show and come to the foreground (steal the foreground) without
being topmost.

Any other idea?

Kind regards

Like the Outlook reminder window ... it steals the foreground without
being topmost.

????

Thanks!

Show quoteHide quoteSo, your trying to force a window to steal focus...  Well, in the old
days you used to do that by calling SetForegroundWindow - the problem
is that this won't always work anymore.  Microsoft "fixed" this
function in Windows98 timeframe to prevent exactly what your trying to
do - steal the focus...

Fortunately, there is a way around it.  But, it involves a little more
work - you have to couple the call with a call to AttachThreadInput.
All-in-all your looking at several api calls.  Here is an example in
classic VB, by the great Karl Peterson:

If you need help converting this to VB.NET, let us know.

Hi Tom,

It is already VB. :o)

Well When I try this...

Call ForceForegroundWindow(CLng(myWindowsForm.Handle))

....I get this exception:

"Attempted to read or write protected memory. This is often an
indication that other memory has been corrupted."


Any idea?

Thanks!

It may be VB, but it isn't VB.Net :-)

I didn't download the code, but judging by the timestamp it was last
updated while VB.NET was still pre-release. One thing you might need
to do is update the API calls to the .Net equivalents, and for that
you should see www.pinvoke.net

After the conversion, let us know if the error disappears.

Thanks,

Show quoteHide quoteSeth, you are correct - it's VB Classic.  I'm fairly sure, that I
indicated that in my post :)  If not, I apologize to the OP.

Hi MOJO,

Yes, jsut as Tom stated, calling AttachThreadInput with SetForegroundWindow
will definitely bring your window to foreground. But this is not a
recommended design on Windows, normally, you should just call
SetForegroundWindow. If the Windows finds that the end user is busy doing
operations, it will flash your window with blue colors in the taskbar. This
is a more recommended behavior than using AttachThreadInput.

Furthermore, SetForegroundWindow Win32 API is encapsulated in the .Net
Framework Form.Activate() method.
Public Sub Activate()
    IntSecurity.ModifyFocus.Demand
    If (MyBase.Visible AndAlso MyBase.IsHandleCreated) Then
        If Me.IsMdiChild Then
            Me.MdiParentInternal.MdiClient.SendMessage(&H222,
MyBase.Handle, 0)
        Else
            UnsafeNativeMethods.SetForegroundWindow(New HandleRef(Me,
MyBase.Handle))
        End If
    End If
End Sub

So you may call me.Activate() to bring the form to the foreground.

Hope this helps.

"recommended", but there times when it makes sense - like the Outlook
notification type windows as the OP mentioned.  So, could you call
AttachThreadInput and then call Form.Activate?  I might have to try
taht :)

Hi Tom,

Yes, if you really have such requirement, you may p/invoke
AttachThreadInput and then call Form.Activate.

Additionally, I am not sure if Outlook calls AttachThreadInput internally,
but I do not think so. Because while I am performing daily works, the
Outlook Reminder or New Item Alert dialogs will just flash in the task. It
seems that they will not jump to the foreground rudely. Anyway, this is my
usage experience of Outlook :-).

Thanks.

HI guys,

Do you both make anti spam software to sell as everybody is setting there
spam on top of all other applications and make with that using the computer
impossible.

Please don't support this so much?

Cor

I forgot to tell the reason not to support it to much, now this thread has
almost every search word in it to search how to do it on Internet.

Hi Tom,

I'm not talking about the Outlook new message popup - I'm talking about
the reminder popup. On my PC the reminder popup steals focus.

Show quoteHide quoteIIRC for showing an application without stealing the focus, you have
to override the sort-of "hidden" property ShowWithoutActivation to
always return True. I used this a few years ago when I wrote a
reminder program that operated like the Outlook reminder (fading in
with a message unobtrusively, and then fading out if ignored by the
user). Oh, the memories.... :-)
