I was working on a large project in VBP and I realised that it was getting out of control, unmanageable and needed split up into smaller modules.

I now have my code split up into smaller more manageable units (Setup.dba, Loader.dba, Main.dba etc...) with Main.dba being the entry point. I've used the #include to link the other files on a first level basis from the Main.dba. I now intend using the #include in the lower level files (Setup.dba, Loader.dba) to link to other smaller function files. This can lead to multiple includes of the same file into a project, I know that C++ uses the (#ifndef, #define, #endif) commands to block multiple declarations.

Q1. is there support for these commands (or similar) in DBP ?


Q2. is there a way of passing a variable BYREF into a function? (see bellow)

the above code should print 10,
the above code is very simple, I don't want to return a value EndFunction rVal as the function will be adjusting several non global variables.

adding the * didn't work...

There is not native support for #ifdef and the like, but two people on the forums have implemented c-style preprocessors for dbp. One is dbpre and can be found here:

And the other is by DSG, and can be found here:

Hope that helps.

No, there isn't.

What I would suggest is to get rid of all instances of the #include command and instead use the IDE to include your sub-code. That way you will only ever have one copy of each part of your code.

Thanks MilkMan that pre-processor looks good.

@Scraggle - that is only useful for small projects, if I have modules that call modules that call modules then that method would require checking the modules to see what they require to be included (in a small project that'd be fine) in bigger projects it's not.

DBPro doesn't mind you including the same file more than once
