R

While they are not shown explicitly in the block diagram, there are other files

that must be present for a Windows application to run.  Some applications reĆ

quire only the main executable (or .EXE file), but most require the .EXE, one or

more DLLs (either the type supplied with Windows or DLLs specific to the apĆ

plication), as well as data files.  If one or more required files are not present,

then Windows fails to load the application, and offers the following helpful" erĆ

ror message:

Cannot find file or one of its components.

If you see this message when you doubleĆclick on an application's filename in the

File Manager, it usually means that one or more DLLs are either not present or

not in a location on the disk drive that is accessible via the path.  Unfortunately,

Windows does not provide much assistance in helping you to determine exactly

which files are missing (the above message is an example).  Determining which

files are missing is largely a matter of trial and error, unless you are able to deĆ

termine exactly which files the application is expecting to have available on the

disk.  For assistance in determining what these files are Ċ in reference to an apĆ

plication that is documented in this programming guide Ċ see the appropriate

paragraph (for that application) in this section of the document.

The shell is the first program that Windows starts, and it is the program that

causes Windows to exit when it shuts down.  By default, Windows uses the ProĆ

gram Manager as the shell.  Ordinarily, almost any application can be desigĆ

nated as the shell, and one of the basic requirements of a shell program is the

ability to launch other applications.  Rather than require special programming

on the part of the customer to implement shellĆlike capabilities, the PEN*KEY

6000 Series Computer uses an invisible" shell program that, in turn, invokes

the main application program.  To see how the File Manager is launched from

the shell program, refer to the NORAND Windows Shell paragraph, in the SupĆ

porting Windows Applications section.

The retail Windows program comes with several fonts.  There is also a considerĆ

able aftermarket for addĆon fonts.  Fonts are usually in one of two categories:

"

BitĆmapped fonts have a filename extension of .FON.  At least one of these

fonts must be present for Windows to use in building dialog boxes and meĆ

nus.  The NORAND minimal Windows configuration includes three bitĆ

mapped fonts: VGAFIX, VGAOEM, and VGASYS.
