I like to have a new Call DLL Action similar to the functionality in Installers like InstallAware.
I want to specifiy the DLL, DLL exported functions and the necessary parameters.

Thanks for the suggestion Martin.
Out of interest, what sort of things would you use this for?

For some projects I need to do some custom steps before I can run a test case. These custom steps (like installing a special driver) are already inside of my installer DLL.
Today I have to create an additional wrapper around this DLL to add this step to FB. If I can call a DLL directly I can skip those wrappers.

Tate,my Windows Installer actions use this to install a MSI file. I think all stuff is available in the current FB installation to make a custom action to execute dll functions… Let me find this out and come back to you.I might even find the time to have a look and create it…Raoul

Done a bit on this tonight. Not yet finished and I don’t know for sure if my idea is going to work…
If not I’ll send you the raw material so you can use VBScript to call functions in a dll.
