Hi Tom

Under Win2k, XP, the whole idea is that it's up to the user how they want to run their DOS app. They can choose the dimensions of the box, the number of characters, the fonts, and the number of lines.

As I see it, this is exactly as it should be.

It could be argued that if an installer changes these settings it's either a security breach or an unfriendly application.

However, a possible solution would be to distribute a shortcut with your app that starts the app in the exact way you desire. This avoids trashing their chosen user-wide setting.

Anyway, you should never try to change HKCU from an installer.

[freedos] Installing a DOS App and Having it Run Fullscreen?

OS=Win2K or WinXP
I'm aware of the Alt+Enter to toggle between full and window mode. I can also get fullscreen by choosing the option in the properties section of the icon, then right-clicking on the title bar of the DOS screen, going to Properties | Layout, and making the dimensions of the screen buffer size and window size 80x25. That works beautifully. What I am trying to do is create an install script that does this automatically. It looks like there is a registry entry created when you go through the procedure to set the screen to true full-screen. The registry entry is located here in the registry:

Basically 2 settings seem to affect the full-screen option:

ScreenBufferSize = 1638480(decimal)

WindowSize = Deleted

When I modify these entries with the install script, I don't get true fullscreen. The DOS section of the screen is full, but the data, or application only uses the top half of that screen. Is there another registry entry that needs to be modified to make my DOS application run true fullscreen?
