In your case i will use Delphi, with the Multi-Media Player component, that you can play, pause, stop, FF, FW, also in movies... And for the lyrics that you want to play(i understand this) you can use a Timer to put the in a TextBox or something else.
Hello, I'm beginning in the OS development(In Assembly, Nasm as Assembler) and i need to implement a command-line on it, but i don't know how to do this, but what i want to say as command-line is like MS-DOS or UNIX:
> ver
BerlOS v.0.0.1
> _
But i don't know how to do the input method(ver in the command). In the repetition of the > before the user input things i know, i only need to do a JMP to the section that prints the > and the input method, if it's needed, here is my code:

Hello, I'm trying to write my OS to an floppy disk, but when i try to boot up, Bochs says that i don't have any OS on that floppy, here is the command that i'm using to write:
#1 Try:
C:\Assembly> DEBUG os.asm
-w 100 0 0 1
-q
#2 Try:
C:\Assembly> DEBUG os.bin
-w 100 0 0 1

I'm using more Nasm now, because of my Operational System that i'm developing, then i need to use Bochs, as editor i use emu8086 and i use something of WinHEX to read my executables.
Hello, I'm starting on Assembly and i want to know how i can clear the screen in Assembly, because of my OS. When i run it in Bochs, that boot messages are there and i want to clear they, for a better visual of my OS.
Hello, I'm learning Assembly and i want to know the tools that the other persons use to develop, things like: Nasm, emu8086, WinHex... All the things that you use that are related with Assembly and what the do. Only for improve my tools and my learning.
Now i know, like 42, in hexamal it will be 2A and the calc is this: 42 = 16 * 2 + 10 , because 42 was divided by 16 with the quotient 2 and the remainder is 10, the it will be 2A. Thanks for Jester01 in the ##asm channel of FreeNode that helped me with this!
Hello, I'm starting in Assembly development. Then recently i buy a book of Assembly, in it i have the table with the decimal numbers to hexamals and to binarys, like this:
Dec - Hex
1 - 01
2 - 02
3 - 03
4 - 04
[...]
10 - A
11 - B
12 - C
13 - D
14 - E
15 - F
And at thee appendix of the book i have the conversions of all the numbers and ASCII to hexamal and to binary, but i want to know what is the calc to convert decimal numbers in hexamal, like 63 = 3F , what is the calc that i have to do to tranform 63 in hexamal that is 3F, this is just to learn more.
Hello, I'm learning Assembly and every time that i ask something here in this forum of Assembly the person that reply me is @wildgoose, that is a person that answer to you with respect, gently and much of learned things in Assembly, because of this things and many others i will like very much if @wildgoose be promoted to moderator of the Assembly forum.
Hello, I want to write a *.bin(Assembly compiled file) to an floppy drive, but i don't know how to do this, remember that i have to write to the cylinder 0, head 0 and sector 1, because it's an boot program, only if needed here is the code:
; directive to create BOOT file:
#make_boot#
; Boot record is loaded at 0000:7C00,
; so inform compiler to make required
; corrections:
ORG 7C00h
PUSH CS ; make sure DS=CS
POP DS
; load message address into SI register:
LEA SI, msg
; teletype function id:
MOV AH, 0Eh
print: MOV AL, [SI]
CMP AL, 0
JZ done
INT 10h ; print using teletype.
INC SI
JMP print
; wait for 'any key':
done: MOV AH, 0
INT 16h
; store magic value at 0040h:0072h:
; 0000h - cold boot.
; 1234h - warm boot.
MOV AX, 0040h
MOV DS, AX
MOV w.[0072h], 0000h ; cold boot.
JMP 0FFFFh:0000h ; reboot!
new_line EQU 13, 10
msg DB 'Hello This is My First Boot Program!'
DB new_line, 'Press any key to reboot', 0
It's only to get more answers, because if you post in more sites you have more chances to get an answer, but if you dislike i don't post more in the other sites, only here.
Hello, I'm beginning in Assembly development. When i try to print a word using the variable type DB with the name message, but when i try to execute this program, emu8086 only show me a dialog, not the message, here is an screenshot: http://xs142.xs.to/xs142/09345/imagem568.png
#make_COM#

Hello, I'm learning Assembly. I'm using DEBUG as my Assembler, but now i want to convert a simple code to really Assembly(For emu8086), here is the code as i put in DEBUG:
-E 0200 "0123456789" 24
-A 0100
0D0B:0100 MOV AH,09
0D0B:0102 MOV DX,0200
0D0B:0105 INT 21
0D0B:0107 INT 20
But when i put this code in emu8086 and i try to emulate it, the program gave me two errors. What i have to do?
Hello, I'm a Java developer, but now i'm learning PLT Scheme language and here in DaniWeb we don't have an forum for this language, then if the administrators of this very big and good community add this language to the board i will be very happy.

Hello, I'm really starting in Assembly, but i want to know if it's possible to develop for ARM devices like those who run Windows CE, because i have an Jornada 720 and i want to develop to it, i'm already a Java developer, but Assembly will be another language that i want to learn.
The application that i'm developing is a simple contact book and if you didn't understand very nice my previous post, i need to change my code, in the list registry's form an option that the user can select a contact, click in a Command and it redirect the user to another form that he can see the full details about that contact that he selected, like name, telephone and type.

Here is my code:
