Tab Controls as views

Environment: VC++ 4.2b, Win NT 4.0
I picked up the example of using the tab control as the view, but there is
one problem with it. The tab views are created and destroyed on the fly.
If one of the tabs has a rich edit control on it switching from one tab to
another loses the data unless it is saved off and re-initialized upon
creation, a great waste of time.
I tried to modify the example to create several views that will hang around
such as the multiple view switching examples from MS. The problem I run
into is trying to find the correct placement of the views create call.
Does anyone have any idea of how to use this with views that stay around in
an MDI environment?

Gary,
I've solved similar problems by creating multiple views and making them
visible and invisible at the appropriate times. I'm not clear as to
what your exact problem is, but I've even created separate views for
each tab control and made a view visible when it's tab was selected.
Let me know if this is what you are trying to do and I can probably dig
my old code up.

Hi, for what I've seen in your mail, it seems your are trying to work
with
a form that has a tab wich allows the user to see various information.
I have this kind of implementation in several forms and after much
digging and
example seing I've decided for the folowing approach.
Oops, I almost forgot: Environment: Windows 95, Visual C++ 4.1 and
another thing, I'm not
using Visual C++ tab control, but that's not that important.
I've created my derived class to the control and to each tab I
associate a dialog. The first time
the user selects the tab, the corresponding dialog is created and shown,
while the previous dialog is hidden. And it's all a matter of hidding
and showing dialogs accordingly with the selected tab. The dialogs are
only created if necessary ( selection of the tab) and are destroyed when
the tab is destroyed. It works
quite well, all the code for each page it's inside each dialog, I can
use the dialogs in several
places if I wish and even has "real" dialogs.
Hope this helps in anyway. Bye

Check out Objective Toolkit.
I'm 90% sure our SECTabWnd will solve your problem. It can hold CViews
and doesn't do anything wacky that could destroy the state of your
views.

I have a MDI MFC App and I'm using the Objective
Toolkit 1.2 SECWorkbook (instead of MDIFrameWnd),
SECWorksheet (instead of CMDIChildWnd), and
CFormView's for my views. The SECWorkbook and
SECWorksheet classes allow me to display my CFormView's
in a 3-D tabbed format. Cool stuff. Excellent product.
I was using them in a VC++ 4.2b environment and I'm now
using them with VC++ 5.0 (I had to download a minor patch for
the 5.0 MFC libraries). From what I'm told, there's a new 5.x version
to be released shortly.
I highly recommend the library.

Gary,
I've done this, and it's really pretty easy. My method was to derive a =
class (CtabView) from CCtrlView. I then created views as necessary. When =
the user selected a tab, I showed the view associated with the selected =
tab and hid the currently shown view.=20
I had to override OnEraseBkgnd among others. I can also recommend the =
classes from Stingray Software, you'll have everything pretty much =
pre-coded. If you want sample code from my method, e-mail me back and =
I'll send it along.

I wanted tabs as my main view. I searched the Visionx MFC PRo and went to
their MS knowledge Base page. From there I got the lead to this sample.
I am mailing you the example put up by Microsoft at their site. Its a
Winzip file 'psmain.zip'
[Moderator's note: Sorry, but I'm not mailing enclosures like this
to 3000 people. It's at Microsoft's web site.]
Hope it solves your problem.
BYe,
Regards

Are you talking about the PSView sample from microsoft? it's SDI but it
only creates dialogs once upon startup.
It's in the KB, Article ID: Q161886.

If it wouldn't be too much trouble, I would like to have an example to get
me started.
