This is ALL the code. A fixedtext on a datrawindow - simple right? :unsure: :unsure: :unsure:

Error is:

error XS0246: The type or namespace name 'DATAWINDOW' could not be found (are you missing a using directive or an assembly reference?) 4,1 File1.prg XSharpRuntimeApp1
error XS0246: The type or namespace name 'FIXEDTEXT' could not be found (are you missing a using directive or an assembly reference?) 5,1 File1.prg XSharpRuntimeApp1

WTH could possibly be wrong with this please?

In .Net, usually classes have a namespace and a classname, just in order to group them together and avoid name conflicts. For the VO SDK classes, we have use the namespace "VO", so the class names become "VO.DataWindow", "VO.HyperLabel" etc, this is why the compiel does not find them when you use simply "DataWindow".

One option to solve this, is to just use the new full names. Anotehr is to putt a

USING VO

on top of your .prg files.

But the best solution is to jut enable the "/ins" (use implicit namespace) compiler option (in App properties/Compiler page), which will make the compiler automatically resolve those names for you, so you will not need to change anything in your code.

Since you are porting code from VO, it is probably a good idea to enable most of the options in thsi page, at least the /vo* (and /lb for late binding) options, which make the compiler behavior compatible with that of VO.

Edit: Of course before all that, you must have added references to the VOSDK dlls!

Brilliant. Thanks very much Chris.

Actually that didn't work. I've basically added every .dll file I can find, and it's made it worse. Also I put the compiler options as you suggested, but the error still remains...
