- /FHQ3: What types of programs can DESQview run?/FB
-
-
-
- There are three types of DESQview programs: DESQview-oblivious programs,
- DESQview-aware programs, and DESQview-specific programs.
-
-
-
- According to the DESQview manual, DESQview-oblivious programs are those
- which are ``written without any consideration for DESQview''. These
- include standard DOS programs like word processors and spreadsheets.
-
-
-
- Some standard DOS programs have the ability to detect the presence of
- DESQview. These programs are considered DESQview-aware. The advantage
- of DESQview-aware programs is better system performance, because
- DESQview does not have to make conservative assumptions about the
- program. A DESQview-aware program gives up the CPU when it doesn't need
- it, and if it writes directly to the screen it instead writes to a
- DESQview-provided video buffer so it can run in a small window /JB(see Q23)/q23.txt/. If you'd like to make your program DESQview-aware, there is code
- provided in Appendix J of the DESQview manual.
-
-
-
- DESQview-specific programs can only be run while DESQview is active.
- These programs use the window management, interprocess communication and
- other services that are built into DESQview (called the DESQview
- Applications Program Interface (API)).
-
-
-
- DESQview will multitask all programs, regardless of type.
