Case Studies

VSGuard

Earth		Earth is a free program that uses the VSOP87 planetary theory to compute the heliocentric ecliptic longitude (L), latitude (B) and the distance to the sun (R) of the planet Earth over a period of several thousands of years. This case study concerns errors that were introduced when the program was converted from VB 6.0 to VB .NET.
Matrix Multiply		SimpleMatrixMult is a small Visual Basic 6 application, which performs a matrix multiplication on two supplied matrices that have user defined lower array bounds of one
DLL Uprgade		Describes the use of VSGuard in order to aid the conversion of a DLL from VB 6.0 to VB.NET
Base converter		A simple program that converts numbers from one base to another was translated from VB .NET to C# .NET. Some subtle differences in the languages caused a number of errors to occur in the upgrade.
