Focus Problems with MDI child forms

[Trev Hunter]

Hi Folks,

Sorry if you have seen this post before - I've posted it before, but it
seems to have gotten lost in Outlook limbo - it's visible on the web
interface, but not in any news reader I've tried :S

A while ago, I came accross this post by Armin describing how to reporduce a
focus bug with MDI children. I am currently experiencing the same problem in
my application although I'm not using an ActiveX control directly on the
form as in Armin's example (my 3rd party toolbars and menus could be the
culprits though).

I'm using Visual Studio 2003 with .net 1.1 on Windows XP.

Any help would be greatly appreciated.

Trev.

Problem: A child can not be activated anymore by clicking in its
client area. It can only be activated by clicking the title bar. Also
the title bar does not always have the expected color depending on
the focus. Is this a known bug? I googled and search MSFT KB but
didn't find anything. Steps to reproduce:
1. New WindowsApplication
2. Add two new Forms (Form2 and Form3)
3. For Form1: Set IsMdiContainer=True
4. Add the following code to Form1:

Private Sub Form1_Load( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load

Dim f2 As New Form2
Dim f3 As New Form3
f2.MdiParent = Me
f2.Show()
f3.MdiParent = Me
f3.Show()
End Sub

5. On Form3, add an ActiveX control, e.g. WebBrowser (shdocvw.dll)
6. Start

Hi Trev,

Is there a reason you did not include the newsgroup

microsoft.public.dotnet.languages.vb in it,

that is the group where Armin is the most active from the international
groups, but not in the ones you have included I thought.

And as far as I have seen in the newsgroup is Armin in the newsgroups one of
the real MDI experts.

If you even want to have more success you can ask it also in the German
language in the newsgroup

microsoft.de.german.entwickler.dotnet.vb

Cor,

I didn't post it to the VB group because I thought it was a more generic
problem (hence the .windowsforms group). I added the .faq and .general
groups because I was having problems with the .windowsforms group and was
hoping for a better response. Surely someone else out there has come accross
this problem before? I'll do up a sample project and see if it is limited to
VB.

that is the group where Armin is the most active
Thanks for the tip about Armin's whereabouts ;) He's the one who posted the
original article a while back, but there was no responses to that. Next time
I see him in a group, I'll discretely OT the thread and ask him.
If you even want to have more success you
can ask it also in the German
language in the newsgroup
Unfortunately I can't speak German - only English, VB and passable C# ;)

Thanks again for the tip,

Trev.
