Point Import Control (PIC)
PIC is a component that is used to import points from various file formats.
It's easy to use and master, and really fun to customize. It supports delimited files, constant width fields, invarious line formats etc.
The user can export the selected points to many other formats, to Microsoft Excel, etc.
It's written entirely in .NET (Visual Basic, still can be used in C# or any other .NET language), source code is also available on demand.
