dos

问题 I'm taking a course on Microprocessor Programming as part of my Electronic Engineering degree. Unfortunately, in the labs, we have to work in DOS using MASM. Now, I don't really find DOS a hindrance, but I just don't have it on a computer at home (and none of the computers that I have have floppy drives), so I am unable to practice writing programs. I have tried under Windows, but it just doesn't assemble (I am guessing this is because of Protected Mode). Any advice on what should I do?

问题 code to take input string assemble using nasm on windows machine: nasm file.asm -o file.com ;read the string mov ah,0x0A ;read mov dx,buffer ;pointer to buffer int 0x21 ;newline mov ah,2 mov dl,10 int 0x21 mov dl,13 int 0x21 ;put $ sign at end of string mov bx,buffer+1 mov dx,buffer+2 add dl,byte[bx] mov bx,dx mov byte[bx],'$' ;output mov dx,buffer+2 mov ah,9 int 0x21 ;exit mov ah,0x4c int 0x21 ;buffer buffer: db 255 ;len of buffer db 0 ;num of char read db 255 ;actual string ;###############

问题 I have a simple requirement of printing text files from Windows (MS-Dos). Let's assume that my normal text file resides on "C:\Temp" folder. On the other hand, I have a EPSON TM88V receipt printer. I am able to shake hand with receipt printer connected on USB and able to print it with below command: C:\Temp> PRINT /D:\WORKSTATION\EPSONTM-T88V C:\Temp\HelloWorld.txt Though it's printing; but it's not cutting the paper. I need to insert those ESC/POS commands in my text file and pass it on to

问题 I am using Process.Start to run a console application on the ASP.NET server and the parameters of the program need a path that is formatted in the old MS-DOS 8.3 format. For example in a console name of the folders in this format can be obtained by typing "dir /X": How can I obtain Server.MapPath() formatted with the short names version(8.3 MS-DOS format) of the folder names? 回答1: This is not available as managed API... You will need to use P/Invoke and call GetShortPathName on the result of

问题 I am creating an MS DOS batch script that needs to list every .bat file in the current directory, but not show autoexec.bat or other utilities or systems .bat files that shouldn't be run by the user. I currently have DIR "*.bat" /B /P This lists all .bat files appropriately, but it shows autoexec.bat. How would I exclude that from the list? Also slightly important, how could I chop off the file extensions and show more than the 7-characters DOS limits files to? Constraints: I am not able to

问题 My question basically says it all. I am getting this: C:\DOCUME~1\frew\MYDOCU~1\Code\AIRCRA~1\lib\ACD\VALIDA~1.PM and I want this: C:\Documents and Settings\frew\My Documents\Code\aircraft_ducting\lib\ACD\Validators.pm I looked at File::Spec::Win32 but that didn't seem to have anything that would do the trick. Ideas? Thanks! 回答1: You can use Win32::GetLongPathName($path) from the Win32 module. 回答2: Win32::GetLongPathName() is all you need. 来源： https://stackoverflow.com/questions/770171/how-do

问题 I need to call some DOS interrupts (Services) from a C/C++ program, I tried the following inline asm code: (Read a character) int main() { asm( "movb $0x01, %ah;" "int $0x21" ); system("PAUSE"); } But it did not work ! I would like to know what have i done wrong here ! Also if there is another way to call dos interrupts ! Thank You ! 回答1: You can only use DOS interrupts from DOS programs, so to make this work, you'd need a really ancient C++ compiler like Visual C++ 1.0 or 1.5, or Turbo C++
