How to modify an application to make the windows internal procedures instead
of storing them in an external window, (.DBW), file.
We will convert the "CASHCODE" tutorial database application for use as a
common reference.
Step 1 Convert the windows to procedures.
Use the DataBoss utility "PROCWIN.EXE" that will allow you to view a ".DBW"
file and will generate the code for the windows.
Load CASHCODE.DBW then Choose "C Function" followed by "All Windows".
You are prompted for the DOS name of the file to write the code into, enter
CASHCODE.WF into the box provided. Now you are prompted for the base name
for the procedures to be written, into the bow type:-- InternalWindow
this means that you will get two functions, (as there are two windows),
called InternalWindow1 and InternalWindow2.
Now quit back to DOS.
Step 2 Create a custom skeleton.
Copy DBC.SKL to CASHCODE.SKL then make the following modifications just
before and inside the "do_menu()" Function.
#include "cashcode.wf" /* Include the code for the windows */
void do_menu(void)
{
int b; /* modified from byte to int */
uchar ctlkey;
int err;
string ts;
uchar yes[2],tpic[2];
set_addmember(ExitSet,AltX);
if (initdbm()) {
for (b = 0; b < def1.anchor; b++) swapmenu();
strcat(strcpy(uw.wfnam,applname),".DBW");
/* Generally initialize the screen and window variables */
/**/ uw.scrmode = 25;
/**/ backfillch = '░';
/**/ winscr.wincolr = 31;/* High Intensity White Forground/Blue Background */
/**/ uw.bgw = NULL; uw.bfchar = backfillch; uw.bfcolr = winscr.wincolr;
/**/ for (b = 0; b <= MaxWins; b++) uw.wa[b] = NULL;
/* Set the variables specifically for the CASHCODE example */
/**/ uw.bgw = InternalWindow1(); /* Background window */
/**/ mdate.m = 0; mdate.x = 24; mdate.y = 1; /* Date display */
/**/ mtime.m = 1; mtime.x = 68; mtime.y = 2; /* Time display */
/**/ mksta.m = 0; mksta.x = 63; mksta.y = 23; /* Key status display */
/**/ mpath.m = 0; mpath.x = 2; mpath.y = 3; /* Path display */
/**/ uw.wa[1] = InternalWindow2(); /* The first entry form */
/**/ err = 0; /* Clear "Error" flag */
/** err = initwin(&uw); **/ /* Comment out old initialization function */
if (err == 0) {
Step 3 Generate compile and run the modified application.
Just follow the usual DataBoss generation steps for CASHCODE except remember
to change the generate screen so the skeleton used is CASHCODE.SKL in place
of DBC.SKL.
