Molecular Weight Calculator - VB.NET DLL Version

The MwtWinDll.NET program contains utility functions for calculating the molecular weight and percent composition of chemical formulas and amino acids. It recognizes user-definable abbreviations and custom elemental isotopes. It also includes a Mole/Mass Converter, Formula Finder, Capillary Flow Modeller, Amino Acid Notation Converter, Isotopic Distribution Calculator, and Peptide Sequence Fragmentation Modeler. Although the DLL is a VB.NET application, it is C# compatible.

To use the MwtWinDll.NET program you need to include it in a .NET project. The Peptide Fragmentation Modeller program is simple VB.NET command-line an application that demonstrates the use of the MwtWinDll.NET program. Also available for download is a simple C# demo application that demonstrates the use of MwtWinDll.dll with C sharp.
