using PB dll in external program

[zorro11]

My problem is the following:
I built my PB application (version 8.0.1) as a dll file (that means only a small executable and a large dll). Can this dll be used by other programs (PB or something different like a self written C++ application)?
I already tried to access the dll with another PB application but got an runtime error "Bad runtime function reference"
Would be glad for any tip

Hi,

I've not tried calling a PB-generated dll from a different program but found that I would get the "Bad runtime function reference" error (and similar) for the following reasons:

1) I had spelt the function name wrong in my external function declaration
2) I had supplied the wrong number of arguments, so the signature did not match.
3) I had supplied the wrong type of arguments, also caused signature mismatch.
4) I had attempted to access a protected or private function.

You might need to make your functions use reference arguments rather than value arguments and/or check the mappings from your external program's datatypes to PB's datatypes - there is a page in the help showing C/C++ and PB datatype mappings which might be useful to you.

Cheers
