Hello Netters!!
I'm fairly new to programming in windows, and I have two questions
that I just can't seem to get answered.
1) Is it possible to hidden page animation? I have a few programs that
I would like to write in windows that would need this feature.
If not, does anyone know of any little tricks where this could be
simulated?
2) Is it possible to write a program that can run in dos and in Windows?
What I mean is: Can my program check to see if windows is present.
If so, it will use windows. If not, it will use a less professional
looking form of interaction. If a program can't run in both dos and
Windows is possible to make windows apart of my program? I've seen
programs such as Excel and Aldus Page Maker do this.

Well, you could use CreateCompatableDC to get a device context that is in memory, not on screen, and then bitblt that onto the screen for the animation effect. Not as fast as page switching but it should do the trick (unless you have very large images to animate). > 2) Is it possible to write a program that can run in dos and in Windows? Yes. Write the Windows and the DOS versions, then use the DOS version as the stub of the Windows program. The "stub" of a windows program is usually a very short .EXE that says "This Program Requires Microsoft Windows" but it could be any program , including a full-blown text version of your program. > If a program can't run in both dos and > Windows is possible to make windows apart of my program? I've seen > programs such as Excel and Aldus Page Maker do this. Not anymore. Windows 3.0 does not have a run-time version. Joel Spolsky spolsky@cs.yale.edu

You can load bitmaps into memory, and draw to memory bitmaps so it would be possible to do hidden page animation. > > 2) Is it possible to write a program that can run in dos and in Windows? It's not really possible to do what you want in one program since a Windows program depends on the entry point being WinMain and a DOS program depends on main. There isn't a convenient (or possible) way to make a program that could support the two different styles of entry. -- "What's in a name?

You can change this to be anything you want. It might be some double work, but DOS and Windows are totally different environments.
