ACAPI_ModulData_GetInfo returns APIERR_BADPARS [SOLVED]

ReignBough — Tue, 01 Aug 2023 12:51:40 GMT

I tried running the following code which is based on the example given at ACAPI_ModulData_Get help:

API_ModulData info;
BNZeroMemory(&info, sizeof(API_ModulData));
GSErrCode err = ACAPI_ModulData_GetInfo(&info, "MyFirstDataBlock");

It returned APIERR_BADPARS which means "info parameter is NULL".

Where did I go wrong?

Hi,

In this case APIERR_BADPARS error means the info parameter is NULL or your AddOn couldn't be loaded properly. Please check your MDID again, and check in Add-On Manager dialog if it shows any warnings/errors!

I tested this with ArchiCAD 17 INT 6540 FULL and it worked good. Soon I'll try it with your version also.

Regards,
Tibor

Thanks Tibor.

I put this code on the CheckEnvironment() function. I was hoping to get the ModulData when the add-on loads.

It works perfectly when I put it on other 'non-required' function, though.

The earliest place for that is the Initialize function; before that the API interface is not fully set up.

CheckEnvironment and RegisterInterface are both called during ArchiCAD start up.
