CDShell+BCDW: graphical menu with confirmation, There is a short HOW TO Options

[pavel]

Hi all,

there is a short how-to for creating graphical menu with confirmation using CDShell with BCDW module (bcdw.csm). The three files (cdshell.ini, menu.gif and confirm.gif) save to the boot folder.

Prepare graphical menu - picture 640x480, save as menu.gif (if you need, increase the picture's size). Prepare another picture, say 320x90 (or any custom size), save as confirm.gif. Prepare cdshell.ini (with menu items related to menu.gif), see my solution:

CODE

# Set graphic mode, say 640x480 or different...
# Show the main menu (picture menu.gif)

bcdw SetGraphicsVideoMode 640 480
begin:
bcdw ShowGif /boot/menu.gif center center

# The main loop waits for pressed keys (loop: ... goto loop)
# If the requested key is pressed ("small" or "capitall" letter), set the BootWhat variable (see example bellow)
# and call YesNo - the confirmation dialog (picture confirm.gif). It allows press Enter/Escape only. If Enter is pressed,
# goto "semaphor" (?) named what BootWhat variable contains ("bootA", ...). Then booting is provided by
# CDShell or BCDW command ("the classic way"). If Escape is pressed in confirm. dialog, then show the initial menu and
# return to the main loop.
#


set BootWhat = ""
loop:
getkey
if $lastKey == key[A] || $lastKey == key[a]; then set BootWhat = "bootA"; then call YesNo
if $lastKey == key[B] || $lastKey == key[b]; then set BootWhat = "bootB"; then call YesNo
if $lastKey == key[C] || $lastKey == key[c]; then set BootWhat = "bootC"; then call YesNo
if $lastKey == key[F9]; then bcdw Reboot
if $lastKey == key[F10]; then bcdw PowerOff
goto loop


# Sub-routine called from main loop with set contents of variable BootWhat. If Enter is pressed, continue booting by
# goto to semaphor (right word?) described by BootWhat. If Escape is pressed, re-draw the main menu and return. Other keys
# are ignored...

YesNo:
bcdw ShowGif /boot/confirm.gif center center
YesNoKey:
getkey
if $lastKey == key[enter]; then goto $BootWhat
if $lastKey == key[esc]; then bcdw ShowGif /boot/menu.gif center center; then return; else goto YesNoKey


bootA:
bcdw SetTextVideoMode
print "Boot from floppy A:\n"
### Enter the right command here...
goto end

bootB:
bcdw SetTextVideoMode
print "Boot BartPE Live CD\n"
### Enter the right command here...
goto end


bootC:
bcdw SetTextVideoMode
print "Boot from hdd C:\n"
### Enter the right command here...
goto end

end:

And the last idea: both pictures (menu.gif and confirm.gif) could be animated!
Hope this will be usufull for you, guys.

My multiboot CD use czech lang, so pictures are useless for you at this time. I make a picture menu.gif using mspaint (belong to WinXP), useing this way: i create the text rectangle and write menu like (A) boot floppy, © boot hdd, (G) boot Ghost and so on (so, my menu.gif is graphical but contains text only). Then i make another picture, confirm.gif using the same method, where the text is like "Are you sure? Enter confirm, Esc escape". Thats all.

Regards,
Pavel
