VB.NET DivRem Example – Code Sample Syntax

VB.NET DivRem Example – Code Sample Syntax

Purpose: – Illustrates using .

Purpose:
takes an dividend, divisor, and remainder as Int32 or Int64
and returns quotient as same data type. Remainder is passed by
reference and it gets updated with the remainder when the function
executes.

Syntax:
DivRem(dividend32, divisor32, byRef remainder32)

Parameters Description
dividend32 int32
divisor32 int32
remainder32 byRef int32

Result Data Type Description
int32 quotient

Syntax2:
DivRem(dividend64, divisor64, byRef remainder64)

Parameters Description
dividend64 int64
divisor64 int64
remainder64 byRef int64

Result Data Type Description
int64 quotient

Prerequistes:

  1. Install Visual Basic (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

Notes:

  • Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
  • You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.vb
