INFO: Differences Between QuickBasic and Visual Basic StatementsID: Q87004
|
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.
WARNING: One or more of the following functions are discussed in this article; VarPtr, VarPtrArray, VarPtrStringArray, StrPtr, ObjPtr. These functions are not supported by Microsoft Technical Support. They are not documented in the Visual Basic documentation and are provided in this Knowledge Base article "as is." Microsoft does not guarantee that they will be available in future releases of Visual Basic.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.
