All there is to the 95 3D look is a new dialog style, #define'd as 
DS_3DLOOK in the Winodows 95 SDK headers.  It's value is 0x4 (which
is just a coincidence with "version 4.0").  Just add this style bit
to you dialog template and, viola!, 3D dialogs.  This works for any
dialog window, regardless of whether it was created by a Win32 or a
Win16 app.  You don't need a new compiler, just a style bit.

To use the new common controls, you will need the Windows 95 SDK.  For
this, you must either be on the 95 beta or a Level II member of the
Microsoft Developer's Network.

I've been working on this same problem myself.  I haven't had time to try it 
yet, but I had the idea of keeping two 80x25 buffers.  The first keeps an 
image of what the screen looks like, and the second is for updating.  
Periodicaly, the updated buffer would be compared to the image buffer, and 
only the differences would be repainted.  After repainting, the image buffer 
would be updated.  There would have to be some refinements -- scrolling 
should scroll the window, rather than repainting the whole thing.

I've given up on the idea of using a text control.  It's too slow and 
limited.  I'm just painting text on the window myself.

Since there doesn't seem to be any hardware scroll feature that is used by
a Window function to "scroll" an image, all "scrolling" is done via a repaint.
If there were a "scroll" function, I suspect it would just hid a repaint
from you.  The wouldn't be any real difference in you doing and the system
doing it.

Me too.  Works fine.  I'm still having problems with scrollbars , though.

In MFC I use

so in windows use WM_GETMINMAXINFO

Intercept WM_WINDOWPOSCHANGING, and change the cx/cy of the lparam to be 
what you want if they are too small/to big.

You need to process the "WM_GETMINMAXINFO" message.

I do not know if you are using  a Class library or the straight Windows
SDK. If you are using the SDK then to run the program iconsised you
need to call ShowWindow(hWnd, SW_SHOWMINIMIZED) in the WinMain after
you have created the main window and this is normally followed by a call
to UpdateWindow(hWnd);

To stop the icon being opened you need to process the WM_QUERYOPEN
message in your main window function and return 0.

I hope this helps.

I did try to mail this at first but I got an unknown user error.

I don't have a code example on me, but here is what you need to do:

    1) Process the WM_GETMINMAXINFO message in your window procedure
    2) if I remember right, lParam is the pointer to a GetMinMaxInfo
       (or something similar, check the docs under WM_GETMINMAXINFO)
       struct.  Use that pointer to modify the entries in the struct
       to the size that you want to limit your window to.
    3)  Pass the message on to DefWindowProc

        Public responses to public questions are even better!!! :)

        Set WNDCLASS.hbrBackground=NULL when you RegisterClass().
        Respond to WM_ERASEBKGND and BitBlt() your bitmap.

        Just BitBlt() it many times to the screen, with a different (x,y)
        for each one.  Try it and see. Enough questions.  Start writing
        20 lines of code and try it and see what happens.

I would create a brush with the bitmap you want to display as the background
and then use that brush as the hbrBackground of your WNDCLASS.

Example:

HBITMAP hBitmap;
HBRUSH  hBrush

//Load bitmap from a resource.
hBitmap = LoadBitmap (hInstance, IDB_YOURBACKGROUNDBITMAP);
hBrush = CreatePatternBrush (hBitmap);

//When initializing your window class (prior to registering it).
wndclass.hbrBackground = hBrush

//Delete objects
DeleteObject(hBrush);
DeleteObject(hBitmap);



This repeatedly paints the background with the bitmap you specify.
Hope this helps, it has worked for me in the past.
