Visual Basic Codes



  1. Visual Basic Sample Codes Visual Basic 6 is a third-generation event-driven programming language first released by Microsoft in 1991. In VB 6, there is no limit of what applications you could create, the sky is the limit.
  2. Visual Basic has a simple syntax much of the language is easily understandable (that’s why it’s called Basic, doh). A few points: The language is not case-sensitive (So A and a are the same) Lines do not terminate with semi-colons Code is in code blocks, but not your standard Java or C# code block.

Language support for DOS assembly,may be suitable for studying MASM/TASM in DOSBox and the course principles& peripheral technology of microprocessor.

  • (Language Support) Offer grammar,basic outline view,hover,code formate support for DOS assembly language
  • Run and debug assembly with right click on the VSCode editor panel. You can choose using MASM or TASM in the preference-settings.
  • Diagnose: process the output of ASM tools and display them in VSCode
  • (suitable for all OS) use JS-Dos to run your asm program in VSCode webview
  • For windows, also support use DOSBox and MSDOS player. All needed tools have been packaged in the extension. Just install and enjoy!
  • For other systems: also support DOSBox. You need to install DOSBox first
  • Note: this extension is built for assembly in DOS, so it not works well with assembly for win32

Demo

Now the extension supports using JSDos to run wdosbox in VSCode's Webview. Change the masmtasm.ASM.emulator in settings to jsdos to try it. And I am trying to make the extension more friendly to nice project like http://blog.swishscripts.com/2021/02/11/cloning-nes-tetris-in-x86-16-bit-assembly-part-1/

Demo 1: Run and Debug Assembly

using TASM via DOSBoxusing MASM via msdos-player

when you are editing assembly files ,you can right click at the editor panel,then you will see several choices listed below:

  1. Open Emulator: Open the dosbox, prepare the environment
  2. Run ASM code: Assemble,link and Run the program
  3. Debug ASM code: Assemble,link and Debug the program

NOTE:

  • If your files path is not workable for emulator. The extension will copy your file in active editor to a separate workspace and operate it there.
  • Default is using DOSBox and TASM,you can change them in preference->settings like the second gif(using MASM via msdos player).
  • If you use include to include another file or use extern, please use dosbox here(see demo2)

Visual Basic Programming For Beginners

Demo 2: Open dosbox and type the command you need

Single-File (command Open DOSBox)Multi-Files (command Dosbox here)
  • Editor Command 'Open Emulator':Open emulator at your file's folder. If your file's path is not readable for DOS emulator, your file will be copied as T.ASM in DOS emulator. (For DOSBox, copy your file to work space folder and mount this folder to DOSBox disk D:)
  • Command 'Doxbox here': The extension will Open DOSBox and mount your active editor file's folder directly to DOSBox 's disk D: with no path-checking.
  • some ASM commands you may need: ASM_commands.
  • Some interesting assembly codes you may need: DOSBox ASM codes

Demo 3: code Formate,Diagnose and more

Formate CodesDiagnose

The extension offer some programmatic features like 'hover','formate','jump to definition',you can close them in the preferece->settings

For other system

Visual Basic Codes

The extension is packaged with needed tools for windows inside while other OS users should make sure DOSBox can be opened by shell command. We can download DOSBox from its website:DOSBox

Visual Basic Codes For Calculator

For MacOS (Darwin),the extension will use command open -a DOSBox --args to open DOSBox. So you need to:

  1. download dmg file from DOSBox's website
  2. Double-click the .DMG file to mount it. A new Finder window showing its contents should appear.
  3. double-click the mounted volume on your desktop and drag the app icon from there to the “Applications” icon in the Finder sidebar.

For Ubuntu and other linux system user,The extension will use shell command dosbox to open DOSBox. We can use command like this:

You can also use the setting ID masmtasm.dosbox.command to set your command for the extension to open DOSBox.

Extension Settings

for more,please see the preference->settings

  • masmtasm.ASM.MASMorTASM use MASM or TASM assembler in DOS emulator to run and debug assembly
  • masmtasm.ASM.emulator choose DOS emulator
    • jsdos (recommend) run in JS-DOS in VSCode's webview
    • DOSBox (default) more stable
    • msdos playerquiet, it runs in command prompt(CMD). So it cannot support GUI like TD.exe
    • auto use DOSBox and msdos player
      1. use msdos-player to compile and link
      2. use DOSBox to run
      3. use msdos-player for MASM(debug)
      4. use DOSBox for TASM(TD)
  • masmtasm.ASM.savefirst save file first before using
  • masmtasm.dosbox.run：what to do after run your code in DOSBox
  • masmtasm.ASM.toolspath: (usually do not need it) use tools from this path, see about-tools
  • masmtasm.dosbox.config: set the DOSBox configuration. The setting will be write to a .conf file which will be used by the DOSBox launched by the extension. Set the configuration like below:

string replacer

the string replacer for settings masmtasm.dosbox.more,masmtasm.jsdos.more,masmtasm.msdos.more. How to set up gmail on iphone. Extension will replace these strings to relavant value.

stringreplace to
${fullname}the fullname of the source code file likec:asmhello.asm
${filename}the filename of the source code file like hello
${fileFolder}the folder path of the source code file like c:asm
${fileDisk}the file disk of the source code file like c
${toolpath}the folder path of the asm tools including MASM and TASM folder

About DOSBox 's disk

The extension will mount some folder to DOSBox 's disk. Please don't modify them.

in DOSBoxreal path in the computer
C:the path of tools folder
D:the path of the work space

known issues

  • lack of support of assembly in not just one file

About tools

Basic

How the extension use tools

The extension will use the tools in the extension's folder tools. If defined the setting masmtasm.ASM.toolspath, the extension will use ASM tools in this folder instead. This may cause problem

See built-in-tools

Visual Basic Codes

where-are-extensions-installed

According to VSCode-doc, the extension will be installed in following folder:

  • Windows %USERPROFILE%.vscodeextensions
  • mac-OS ~/.vscode/extensions
  • Linux ~/.vscode/extensions

use your tools

if you want to use your tools of assembler, please paste your path to the setting masmtasm.ASM.toolspath, your files should follow the structure like tools
