It sounds to me like you are distributing the forms/reports/labels etc to the clients. If you build an EXE, then you shouldn't get the "path" problem as VFP will embed the resource (in this case icon) into the exe and will know how to extract it at runtime.

I think it's just as important for generated code to be readable and follow normal coding styles. At some point, someone is either going to need to debug the code or otherwise see what is happening "behind the scenes". |

See divert sockets: [Divert Sockets mini HOWTO][1].
They work by passing traffic matching a certain ipfw rule to a special raw socket that can then reinject altered traffic into the network layers.

This is one of those cases where a surrogate kay pretty much *always* makes sense.

If performance is important and most queries are read-only, I would suggest to replicate data over to another database. While this seems like unneeded duplication of data, it might help if indexes are required.

How do I edit work items in the Visual Studio 2008 xml editor? |

Check out [Implementation Patterns][1] by Kent Beck. There is a particular pattern I am thinking of that may help in this situation... it is called "Guards".

It's quite possible that somebody in the future will want to go through and see what your code does. So making it somewhat understandable is a good thing.
You also might want to include at the top of each generated file a comment saying how and why this file was generated and what it's purpose is. |
I think that depends on how the generated code will be used. If the code is not meant to be read by humans, i.e. it's regenerated whenever something changes, I don't think it has to be readable. However, if you are using code generation as an intermediate step in "normal" programming, the generated could should have th... |
Generally, if you're generating code that needs to be human-modified later, it needs to be as human-readable as possible. However, even if it's code that will be generated and never touched again, it still needs to be readable enough that you (as the developer writing the code generator) can debug the generator - if yo... |
