Is there something already done to get absolute path from relative path, and
relative path from absolute path:
Example:
BasePath="c:\a\b\c"
RelativePath="..\e\f\g\..\m"
AbsolutePath=FindAbsolutePath(BasePath, RelativePath)

and the same in other direction
 
AbsolutePath=FindAbsolutePath(BasePath, RelativePath)

AbsolutePath = Path.GetFullPath(Path.Combine(BasePath, RelativePath))

and the same in other direction

Nothing in the BCL but there's the native API PathRelativePathTo.

How do I use it from VB.NET?

....

Const FILE_ATTRIBUTE_DIRECTORY As Integer = &H10
Dim relativePath As New StringBuilder(260)
PathRelativePathTo(relativePath, "C:\Windows\System32",
FILE_ATTRIBUTE_DIRECTORY, "C:\Program Files\Microsoft Visual Studio
..NET 2003", FILE_ATTRIBUTE_DIRECTORY)
Console.WriteLine(relativePath)

' Prints ..\..\Program Files\Microsoft Visual Studio .NET 2003
