X# Runtime and VO SDK Reference

This is the generated documentation for the XSharp Runtime and VO SDK.
Please note that DotNet does not know the concept of a function. Therefore the compiler converts functions to static methods of a compiler generated functions class.
The same is true for DEFINES. These are added as constants fields in the functions class.
The XSharp runtime has a couple of these classes:
There is no need to do anything special when writing code. The compiler will automatically resolve function calls, such as: Left(cString,10) and will generate the following output XSharp.Core.Functions.Left(cString,10). The compiler will also translate a define such as FA_NORMAL to XSharp.Core.Functions.FA_NORMAL.
In fact the compiler will include the value of this DEFINE in the generated code. You will not be able to see in the generated code that the value 0x00000080 was read from the FA_NORMAL define.
The source code for the XSharp Runtime is available on GitHub.
If you find bugs with this code, please report them by sending an email to bugreports@xsharp.eu.
Or even better, locate the bug and send us a bugfix.
The best way to do that is :
  • Create a Fork of our Github repository
  • Create a unit test in the appropriate unit tests project
  • Fix the problem
  • Send us a pull request for the unit test and the bug fix
Of course you can also discuss issues you have or send us your comments on the forum on our website
Finally, if you like what you are seeing, you can help to support the X# development by subscribing to the "Friends Of XSharp" (FOX) program.
More information about that program can be found at our website as well.
Namespaces
NamespaceDescription
Advantage
This namespace contains the exposed RDDs for Advantage.
VO
The VO Namespace contains all the VO SDK Classes, such as DbServer, DataWindow, SQLSelect etc.
If you enable the compiler option to search inside "Implicit Namespaces" (/ins) then you will not have to include a USING VO statement in your code.
The compiler will then automatically find the classes.
The Runtime will also respect these implicit namespaces, so CreateInstance(#DbServer) will also be able to find the DbServer class inside the VO namespace.
