Differences Between QuickBasic and Visual Basic Statements

- Standard and Professional Editions of Microsoft Visual Basic for

  Windows, versions 2.0 and 3.0

SUMMARY

The following is a list of statements and functions not shared between Microsoft QuickBasic version 4.5 for MS-DOS, Microsoft Visual Basic programming system version 1.0 for Windows, and the Standard and Professional Editions of Microsoft Visual Basic version 2.0 for Windows.

MORE INFORMATION

The following table compares reserved words in QuickBasic for MS-DOS to those in Visual Basic for Windows.

NOTE: Frequently a statement or function is not supported in one language or the other because there is a different approach to achieve the same result. A good example of this is the LPRINT statement in QuickBasic. Visual Basic has a Printer object that handles the output to the system printer.

In some cases, a statement or function is not supported because it is a low level MS-DOS operation that conflicts with Windows, or it is a function that is only supported in Windows.
