Writing a simple basic program

Share on Facebook Writing simple Visual Basic computer code is a matter of utilizing the prebuilt code pieces that come as a part of Visual Basic Express or Visual Studio.

Writing a simple basic program

This is to demonstrate the build process and to explain a few more things. Action Explanation Create a new folder in your c: This helps you organise your work.

You can put all your programming work and tools in this folder or in sub-folders if you prefer. Then using your text editor, create a new file and type these lines: RET Save this file in the prog folder calling it, say, Nothing.

COMPILE THE PROGRAM

This is the "do-nothing" program. It also tells the linker that this is where program execution should start. Now using your text editor, create a new file and type these lines: The first line runs the assembler GoAsm, giving it the Nothing.

This creates the file Nothing. GoLink is also told to create a console program - this is a program which does not make use of the Windows Graphical User Interface it does not have windows.

Go to the "start" menu, programs, and click on "MS-DOS prompt" note the position of this command may differ between computers, for example in XP this is "start", all programs, accessories, command prompt. If you are not used to DOS commands, this will be a mystery to you.

This is pushed on the stack ready to send to the API call as a parameter. Here we ask for handle which is the Standard Output Handle for the console.

The console is the interface with the user, which in this case will be the MS-DOS window also known as the "command prompt".

Using this handle we can write to the window.

It writes the string which is 11 characters long. This is required because WriteFile will report into that dword how many characters it actually writes.

Now you can assemble and link this file using the same techniques as before, but with a slight change. Your batch file will now be:Because most code is in plain text, you can write code using a basic word processor or text editor.

However, it is much more effective to use a software application that is specifically designed. You may wish to copy this program into your C++ programming editor and compile it, just for practice.
